    You will choose to use a capsule to administer medicine but not compress to tablets due to :

    • The drug may irritate the esophagus and gastric mucosa
    • The medicine may have bad taste, easy to volatilize, easy to be decomposed by saliva in the mouth or easy to inhale into the trachea

    Drugs packed in capsules, not only protect its properties from damage, but also protect the digestive organs and respiratory tract.

    Besides, removing the capsule shell may cause dug loss, waste, and efficacy reduction.

    Last, some drugs need to be dissolved and absorbed in the intestine, and the capsule can protect the drugs from being damaged by gastric acid.

    Chapter 2: How many types of Capsules are there?

    Generally, there are two types of capsules: hard capsule and soft capsule.

    Hard capsule, also known as empty capsule, consists of two parts of the cap body.

    Chapter 14:Functional Principle of fully capsule filling machine & semi-auto capsule filling machine

    14.1 Fully automatic capsule filling machine working principle


    The Filling Process 

    From the above filling process, you will clearly see how capsules are made step by step.

    Below you will also learn how a fully automatic capsule filling machine work step by step:

    NJP-1200 Capsule Filling Machine Functional Principle stretch-out view 

    Step One: Capsules rectification

    As you know most empty capsules are joined capsules whose caps and bodies are joined together. For the filling process they must be rectified.

    As you can see above, capsules are randomly poured into the capsule hopper with a plurality of circular channels inside.

    These channels are suitable for a capsule to go through, and the lower part of each channel is equipped with spring pieces.

    When working, the capsule delivery plate reciprocates up and down, and makes capsules enter holes and be stuck by the spring piece. Then the capsule delivery plate moves downward to make the spring piece releases the capsules, and then capsules falls.

    capsules falls

    You may not easy to understand that capsules need further rectification as it may be body end downward or cap end downwards when falling.

    Step Two: Separating the Body from Caps

    You will see the capsule tray is transferred to the capsule separation station, and the vacuum divider raises to make its upper surface close to the lower surface of the lower segment without gap.

    The capsule will be separated by vacuum because of the difference in the diameter of capsule caps and bodies. Capsule caps will be stuck to the upper part of the capsule tray and capsule bodies will go downwards.

    1. Upper Mold 2.Lower Mold 3.Vaccum separation station 4.Separated capsule body 4. Un-separated capsule body 6. Vacuum tube

    Then after separation, you will see the upper and lower part of the capsule tray will be separated and be transferred to their respective stations.

    Step Three: Filling Medication

    You know the capsule body will be conveyed to the filling station for filling medication.

    The step is as following show:

    Filling Medication

    A-F represents each group of punches.

    During the interval time after the punches rise, the powder box rotates at an angle.

    The powder in the hole of the rotary metering disk mold is successively compacted once by each group of punching rods.

    When the filling rod is lifted from the mold hole, the powder box rotates, and the powder on the metering plate will automatically fill the remaining space in the mold hole.

    The fill and compact once, until the sixth time, punch the powder column in the mold hole out of the measuring plate, make it fall into the empty capsule below, and complete the filling work once.

    It has used the relative movement between the powder scraping block and the metering plate, the redundant powder on the surface of the metering plate is scraped off to ensure the metering requirements of the power plug.

    With this method, the dosage is relatively accurate dosage, and the error is as low as ±3%. And it is able to fine-tune the powder plug dose by adjusting the lifting height of the punch.

    Step Four: Wasted capsules rejection

    After the filling process, A few empty capsules are not separated because of some reason. There will be pins corresponding to the capsules.

    If the capsule cap is not separated from the capsule body, the pin will pull the capsule out of the mold, and the capsule will be blown to capsule collecting bags.

    The capsule caps and bodies that are separated will be transferred to the next station.

    Wasted capsules rejection

    Step Five: Capsule locking

    You can see the upper and lower capsule tray rotate to the locking station at the same time, and at this moment, the axis lines of the upper and lower capsule tray overlap.

    Then the baffle plate above the capsule tray and the pin below the tray begin to move to make capsule be locked.

    Capsule locking 

    Step Six: Filled capsuled Locking

    You can see the pin will push the locked capsule out of the capsule tray, and then compressed air blows ejected capsules into the outlet.

    Step Seven: Cleaning

    When the upper and lower modules are dragged by the main working panel and stop at the cleaning station, they are just placed at the gap of the cleaning device.

    At this time, the compressed air is opened, and the pollutants such as powder and broken bag skin in the mold hole are blown out of the mold hole from the lower direction of the lower module.

    The vacuum system above the mold hole will suck it into the vacuum cleaner to keep the mold hole clean, so as to facilitate the next cycle of operation.

    14.2 Semi automatic capsule filling machine working principle

    You will read the following steps to perfectly implement the filling process when using a semi-automatic capsule filling machine.

    Secondly, you will load the empty capsules and the filling medication into respective product hoppers.

    Thirdly, you will power on the machine by pressing the start button for the machine to operate well.

    You should also key in the major operating parameters at the PLC control system to guide the operations of the machine.

    Step Two: Separating the Body from the Caps

    Through the delivery system of the machine, the empty capsules will move from the main capsule hopper.

    The capsules align at right angles in the round capsule tray as it awaits the filling process.

    Before the machine injects the filing medication, you have to remove the caps from the body.

    The upper capsule tray holds the caps while the bottom capsule tray holds the lower body of the empty capsule.

    You will manually remove the upper tray and with it comes out the caps of the empty capsules.

    The body of the empty capsules remain intact and moves around on a conveyor belt awaiting the filling process.

    Step Three: Filling the Empty Capsules

    The machine will initiate the flow of the filling medication into the empty capsules which are at right angles.

    The filling table will position the filling nozzles strategically above the empty capsules.

    The tray will be in continuous motion as the filling medication goes through the nozzles and into the empty capsules.

    With the help of a dosing disk, the machine is capable of controlling the filling quantity and speed as accurately as possible.

    Once all the capsules are full with the filling medication, the machine will automatically retrieve the filling machine.

    Step Four: Replacing the Caps

    You will position the caps tray directly above the body tray that will push the caps onto the body of the capsules.

    Apply a little bit of pressure at the compression zone so that the caps can fit perfectly onto the body.

    Finally, you will discharge the filled capsules from the machine for further inspection and packaging.

    Chapter 15:How to use a fully & semi-automatic capsule filling machine?

     15.1 Operate steps of the fully automatic capsule filling machine 

    You will refer to below steps to operate the machine well:


    AIPAK NJP-1200D capsule filling machine

    Check whether all parts of the machine and equipment are in good condition.

    According to the process requirements, select the disc specification, powder or particle filling system.

    Installation and adjustment: the support and the material tray shall be kept parallel, and the filling rod shall be perpendicular to the support, so as to ensure that the filling rod can freely enter and leave the filling hole of the material tray.

    Loosen the set screw, turn the lock nut to the required height, then tighten the screw and nut, and adjust the height of the filling seat.

    After all the safety settings are correctly equipped and adjusted, turn the machine 1-3 times in the running direction with the handwheel without capsule and medicine.

    And then, under all normal conditions, put the capsule and medicine powder (or particles) into their respective containers respectively, with the filling height of 30mm below the edge of the container.

    Adjust the depth of the filling rod inserted into the material tray. The large filling volume of the capsule is determined by the size of the capsule, the height of the material tray and the compaction degree of the filling rod to the powder.

    Adjust the height of the filling rod.

    In the beginning, the lower end faces of six groups of filling rods shall be on the same

    horizontal plane.

    The insertion depth of the filling rod is determined by the thickness of the material tray.

    The particle filling system relies on the rotating adjusting shaft to move the adjusting parts left and right, and achieves the purpose of adjustment through the volume change. Start the machine and it will work normally.

    Protection of filling mechanism: check the metering bucket regularly and remove any sediment stuck on it.

    Apply a thin layer of grease to the track on the convex roller once a month. Gear and groove cam shall be cleaned and coated with grease once every two weeks.

    15.2 Steps to operate a semi-auto capsule filling machine

    As the above functional principle, you will easy to understand how to operate a semi-automatic capsule filling machine.

    Below is more details for your reference:

    Press the green button in the "power switch" to turn on the power.

    Slowly adjust the "vibration strength adjustment knob" and turn it clockwise.

    At this time, the finishing disk, which is connected with the "vibration support", starts to vibrate. Touch the finishing disk with your hand and adjust the vibration strength according to your feeling.

    Put the powder-filled capsule shell into the "powder-filled capsule shell finishing disk", about 300 capsules each time. Put the capsule cap into the "capsule cap finishing plate", about 300 capsules each time.

    The finishing plate is made of plexiglass plate, on which there are many circular holes with big upper and small lower funnel shapes, the diameter of which corresponds to the diameter of the capsule number.

    At this time, the capsule shell of the working platform plate moves stably and slowly, so that it can enter the hole of the platform plate one by one.

    In about 30 seconds, the powder-filled capsule shell and capsule cap fall into the round hole with the opening facing up. If the individual opening is facing down, the capsule cap can be used to press the sleeve down gently, and then the sleeve can be pulled out.

    Horizontally hold the connecting plate of powder loaded capsule shell, push it in the lower part of the finishing plate, the powder loaded capsule shell in the finishing plate will fall into the circular hole of the connecting plate.

    And then take out the connecting plate. In the same way, take out the capsule cap with the capsule cap connecting plate.

    semi-automatic capsule filling machine have any drawbacks

    A powder square plate with a bottom area of 500 × 500mm and a height of about 10 mm on four sides can be prepared in advance, which is filled with powder, and the connecting plate of powder-filled capsule shell can be placed in the powder square plate horizontally. Then cover the plexiglass frame matched randomly on the powder filling capsule connecting plate, put the powder into the frame with a small bucket shovel, and fill the powder with a scraping on the edge of the frame, and scrape off the excess powder.

    Use the capsule cap cover set plate (as shown at the end of the figure, there are round holes on the set plate), put it on the capsule cap cover joint plate, with alignment holes, easy to place.

    Turn over the capsule cap connecting plate, make the opening of the capsule face down, and cover it on the powder loaded capsule shell connecting plate, which also has a contraposition hole, so it is easy to cover.

    Put the assembled capsule plate into the cavity under the "capsule cap forming plate", pull down the "pressing rod" with your hand and put it in place, do not need to be careful of excessive force, because there is a positioning mechanism to control the pressing height.

    Take out the sheathed capsule plate, pour out the capsule, and fill it. You can cycle to the next board.

    Chapter 16:Fully vs. semi-automatic vs. manual capsule filling machine

    16.1 Fully vs. Semi-automatic capsule filling machine

    A fully automatic capsule filling machine is more faster and automatic to perform most of its functions.

    However, You will need some professional and technical personnel to assist in some activities. To some extent, the semi-automatic capsule filling equipment depends on automation and needs manpower. You will need more manpower to help operate the semi-automatic capsule filling machine to affect the speed.

    Semi-automatic capsule filling machine

    And fully automatic capsule filling machine is a fast, efficient and accurate large-scale capsule filling equipment.

    Last semi-automatic capsule filling machine can be only used to fill hard capsules. Fully automatic capsule filling machine is suitable for filling hard as well as soft capsules.

    16.2 Automatic vs. manual capsule filling machine

    manual capsule filling machine

    • The manual capsule filling machine is a device that you can use to fill empty hard capsules with drugs and nutrients.

    An Automatic capsule filling machine can fill empty hard or soft capsules.

    • With these two machines, it is easier to fill empty capsules of any size with various nutrients or drugs according to your specific requirements.
    • When using a manual capsule filler, you need to hire people to help with most activities.
    • Manual capsule filling machine is slower than an automatic capsule filling machine, which is not conducive to large-scale production.
    • The automatic capsule filling machine is faster, you will only need the least human assistance, but it can carry out large-scale capsule filling efficiently.

    Chapter 17: Capsule size chart fill weight and capacity comparison

    You may often want to know how much does a capsule hold?

    Let me tell you "000" holds about 1000 mg., "00" holds about 735 mg., "0" size holds about 500 mg., #1 holds about 400 mg., #3 about 200 mg.

    capsule hold

    One teaspoon will fill about 7 "0" capsules and about 5 "00" capsules.

    Then you may would like to know each capsule size and filling weight.

    The fill weight depends on the powder density and particle size. Some powders can be much denser than others. But it also depends on how fine the powder is. Because of this, a good way to check is to know the powders mesh size.

    Capsule Size Chart

    Chapter 18:How to maintain a fully & semi-automatic capsule filling machine?

    To increase the efficiency and durability of the capsule filling machine, you must perform proper maintenance and clean.

    18.1 Maintenance of the Fully automatic capsule filling machine

    (1) When the machine works normally for a long time, you will need to regularly clean the parts and components that are in direct contact with the medications.

    (2) You will also need to regularly and appropriately add lubricating oil (grease) to reduce the wear of moving parts to the loading mechanism under the working surface of the machine.

    (3) You need to check the oil quantity of the main drive reducer once a month. If it is insufficient, you should add oil in time and also change the lubricating oil once every half a year.

    (4) You need to check the safety clutch as it plays a protective role when the machine is overloaded. When the load is normal, the clutch should not slip, but it may also slip due to long-term use. When the slip occurs during normal use, you should tighten the round nut of the clutch to ensure the normal operation of the machine and play its protective role.

    (5) The vacuum separator of the vacuum system mainly plays the role of sucking the capsule into the upper and lower modules and separating the cap and the body during the filling of the hard capsule. If the capsule cannot be separated from the cap and the body, the subsequent filling will not be carried out. Every time the rotary table of the machine runs 1 station, the main shaft of the machine rotates 1 cycle, and the vacuum separator moves up and down once under the action of the cam.

    automatic capsule filling machine-10

    If the separation of capsule cap and body is not smooth, you need to check the gap between the upper plane of the vacuum separator and the lower plane of the lower module.

    If the gap is too large, the vacuum degree of the vacuum system will not reach the vacuum degree required by the separation of cap and body (about 0.05Mpa).

    If the gap is too small, it is easy to produce head impact and deform the lower module.

    When the position of the vacuum separator needs to be adjusted, use the handle to turn the main motor shaft to make the vacuum separator rise to the highest position.

    Then you should loosen the locknuts (one is a left-hand nut and one is a right-hand nut) at both ends of the adjusting rod under the machine table, then rotate the adjusting rod to adjust the height of the vacuum separator, then lock the nuts, and use the handle to turn the main motor shaft for a test until it is appropriate.

    The vacuum degree can be seen on the vacuum gauge on the operation panel of the machine.

    When the vacuum is too high, the vacuum degree regulating valve can be opened properly.

    When the vacuum is too low, the vacuum degree regulating valve can be closed or closed.

    So you should regularly open the filter of the vacuum system to remove the blocked dirt, so as to ensure that the vacuum system has enough vacuum.

    (6) You should check the transmission chain once a week and add a proper amount of grease.

    When the chain is too loose, you need to tight again, and you need also tighten again, and move the tensioning wheel for adjustment.

    18.2 Maintenance of the semi-automatic capsule filling machine

    A semi-automatic capsule filling machine is a vibrating machine.

    1. You need to check the fastening condition of screws at all parts frequently. If it is loose, you should tighten in time to prevent failure and damage.
    2. You should place the medicine board vertically or horizontally to avoid deformation and damage.
    3. The shell and body of the electric appliance must be grounded to ensure safety. You must cut off the power after work.
    4. At the end of each day's work, you should also remember to clean the residual drugs on the machine and in the mold hole to keep the whole machine clean and sanitary and avoid washing the machine with water.

    If the mold on the machine needs to be cleaned, the fixing screw can be loosened, and then it can be taken down, which is convenient for installation.

    18.3 How to clean the capsule filling machine?

    To meet pharmaceutical hygiene requirements and improve the filling efficiency, you must know below knowledge for cleaning capsule filling machine.

    (1) Detergents and disinfectants: drinking water, purified water, 75% ethanol.

    clean the capsule filling machine

    (4) Cleaning method: the cleaning shall be carried out in the order of first removal and then washing, first inside and then outside, then whole:

    1) The cleaning steps of producing the same type of capsules:

    First, you need to use a vacuum cleaner and then a soft brush to clean the residual powder in the powder filling device module;

    Second, you should remove the powder punching rod, measuring plate and powder hopper, take them to the cleaning room, wash them once with water, then rinse them with purified water, and dry them with a dry cloth. Wipe and disinfect with a rag dipped in 75% ethanol;

    Third, you need to wipe the part of the equipment in direct contact with the medicine with purified water, dry it with a dry rag, and then wipe and disinfect with a rag dipped in 75% ethanol;

    Forth, you need to wipe the glass protective cover and the surface of the equipment with purified water;

    Fifth, once all finished cleaning, you should hang the "cleaned" status mark after passing the inspection;

    Last, fill in the cleaning record.

    2) If you are producing different types of capsules, you shall also know below steps:

    ① You should remove the capsule barrel and capsule funnel, take them to the cleaning room, wash them with purified water, dry them with a dry rag, and then wipe them with a rag dipped with 75% ethanol for disinfection;

    ② You need to scrub the movable bearing of cam disk with a rag, then scrub them with purified water, and then dry them with a dry rag, after that use a cloth dipped in 75% ethanol to wipe and disinfect.

    Chapter 19:Capsule filling machine FAQ, common problems and solutions

     19.1 How to deal with the failure of semi-automatic capsule filling machine

    If you are failed in semi-auto capsule filling machine filling process, please check below:

    Troubleshoot capsule defects

    Troubleshoot capsule defects-Photo Credits:Vitafoods Insights

    1. The vibration is not ideal, adjust the voltage.
    2. The reed screw is loose, tighten the screw.
    3. The capsule shell is arranged in the working platform plate, and the mouth is higher or lower. Adjust the height of the dislocation plate and the guide rail.
    4. There are too many capstan (more than 3%) and the vibrator is not adjusted properly. Because the proper voltage is adjusted or the size of the capstan is not up to the specification, the qualified capstan is selected.
    5. The capsule shell is stuck on the platen and cannot fall. Replace the capsule shell or adjust the position of the dislocation plate and the hole of the platen.
    6. The mold cannot be reset in the track, the compression spring at the back end of the track is stuck or the capsule variant is stuck. Reinstall the spring or ejector rod, and push the stick to push the stuck capsule down.
    7. Wear of the guide plate in the mold will affect the low rate of capsule assembly. Replace the new mold or loosen the positioning on both sides.

    Fasten the positioning nails.

    Change the capsule shape or wet it.

    Replace the capsule shell properly. 

    19.2 What are the ways to deal with the abnormal situation of the automatic capsule filling machine?

    Yes, any machine will have abnormal situations as a capsule filling machine, then what exactly does it have?

    I.The capsule cannot be separated.

    Capsule shells showing features-Photo Credits:

    The capsule itself needs to be replaced.

    The vacuum is too small. There are many reasons why the vacuum is too small. If the cause of the vacuum pump, you need to find a mechanic to repair it or replace it.

    The air pipe separated from the vacuum pump connecting the capsule is broken. Replace the air pipe.

    The filter membrane of the vacuum pump is blocked. Clean the filter membrane.

    In addition, it may be that the water flow is too small, so you need to replace the larger water flow pipeline.

    Of course, you have to look at the situation to find out why..

    The gap between the module and the shell separator is too large, so the height of the shell separator or the module can be adjusted, or there may be a problem with the expansion rod in the module.

    Of course, it needs analysis. It is easy to have problems if the powder is too thin or too sticky.

     shell separator

    The module is not right.

    Use the debugging bar to adjust the module until it automatically falls into place.

    The powder is too sticky to block the module, and the module should be cleaned.

    II. The capsule head and tail concave.

    Sometimes there is a problem with the capsule itself. You need just replace the empty capsule.

    Then check whether the height of the thimble needs to be adjusted.

    Or you need to increase the stress area of the capsule, which is to make a thicker thimble.

    III. Capsule cleaving

    This is a very headache and is often encountered. It needs to be treated carefully. This phenomenon is generally caused by the following reasons.

    1. The difference between the capsule cap and the capsule body is too large. The capsule needs to be replaced.
    2. Too much powder remained on the module. Module cleaning required.
    3. When installing the module, the upper and lower modules are not aligned, and the module is aligned again. Until the debugging rod can automatically fall into place.
    4. In fact, it is also related to the size of powder particles.
    5. Check whether the locking position of capsule cap and thimble are too high.
    6. Shorten the distance between the upper formwork and the roof.

    Of course, the distance is too short.

    The principle is: before the wedge is inserted, it is locked. This method is really feasible.

    IV. Filling variety

    There is no fixed way to solve this problem.

    Readjust the filling rod.

    This reason is directly related to powder.

    For the sake of equipment, you need to directly refuse to fill and request the granulating post to rework.

    IX. The distance between the powder scraper and the dosing disk should be 0.4mm, as long as it does not touch the dosing disk.

    The increase or decrease of distance can directly affect the loading capacity.

    Sometimes you can try to increase the distance when the loading is too low.

    If the filling rod is not pressurized in the short distance, the loading capacity is too high, please directly request the pelletizing post to rework.

    V. The bearings at the outlet of the finished product, the locking position and the place where the waste bag is removed are blocked, basically because of the presence of the powder after entering.

    You should clean the bearings in time and close the appropriate amount of oil. It is better to add butter at these places than the machine oil.

    After cleaning, ensure that the bearing has been dried, otherwise, it will be blocked immediately.

    Each time the site is cleaned, the bearing shall be removed for cleaning and oiling.

    19.3 Which ingredients can be used to fill the capsule?

    Depending on the type of capsules, you can fill them with different ingredients. Here are the recipes you can fill with different types of capsules.

    In hard gelatin capsules, you can fill the following formula:

    • Powder formula
    • Pellet formula
    • Tablet formulation

    In soft capsules, only the following substances can be filled:

    • Liquid formula
    • Semi-solid formula
    • Suspension 

    19.4 Can a filling machine fill different types of capsules?

    Yes, you can use a capsule filling machine to fill all sizes of capsules.

    You only need to change the tool system of the capsule filling machine from time to time. The automatic capsule filling machine will automatically change the mold system according to the capsule size.

     19.5 What is the capsule filling amount?

    The capsule filling weight is the amount of filling material you will use to fill a capsule. It does not include the weight of the capsule shell.

     19.6. Can the capsule filling machine fill tablets and pills?

    Yes, you can use a capsule filling machine to fill pills and pellets

    19.7 At what speed does the capsule filling machine work?

    The capsule filling machine operates at different speeds depending on the type of machine you are using.

    The speed of the capsule filling machine is usually determined by the number of capsules that can be filled in a given time.

    In the fully automatic capsule filling machine, you will be able to maintain a speed of 60 SPM.

    It can also be lower or higher depending on your production specifications.

    You can get a machine that can fill 180000 capsules in an hour, depending on the speed.

    19.8 How to fill the capsule with essential oil?

    You will use the soft capsule packer to fill the essential oil capsule.

    The working principle of a soft capsule filling machine is the most basic principle of filling essential oils.

     19.9 How can I stop the capsule from leaking?

    You can prevent the capsule from leaking by making sure it's the right combination of ingredients.

    This will result in a strong gelatin wall that is unlikely to leak.

    19.10 What are the common capsule defects in the filling process?

    Capsules are fairly easy to fill, but sometimes things go wrong. Here are some tips on how to stop defects.

    Typical Defects

    Typical Defects-Photo Credits:Pharmaphil Inc., Windsor, ON

    First, before filling the machine's hopper with empty capsules, verify that the capsules meet your dimensional specifications by checking a representative sample.

    Even capsules from the most reputable manufacturers may differ slightly.

    The same is true of tooling supplied by different vendors, so be prepared to make some adjustments.

    Of course, verify your settings and check that routine maintenance has been performed before you start.

    And be sure you understand how the active ingredient and/or formulation can affect filling.

    Next, you should check the environmental conditions within the filling room. Ideal conditions are a temperature of 22°C ± 2° and a relative humidity of 40 to 50 percent.

    If conditions are outside these ranges, allow some time for the room and the materials within it to acclimate before you begin production.

    If defects occur, try resolving the problem using one or more of these troubleshooting tips.

    Lumpy or misshapen capsules.

    If the capsules form lumps or are otherwise misshapen, check the conditions under which they were transported or stored.

    You should maintain empty capsules at a temperature between 15° and 30°C and a relative humidity between 40 and 65 percent.

    Avoid exposing empty capsules to a direct source of light or to heat. Don't transfer capsules suddenly from a high-temperature environment to a low-temperature one.

    Improper rectification.

    If the capsules are not being oriented properly (cap up), first make sure no one is using a plastic container to transport the capsules or a plastic scoop to load the capsule filler.

    Plastic can cause an electrostatic charge to develop, hindering rectification.

    Use stainless steel containers and scoops instead.

    Also check the gate knee and adjust it as necessary.

    Verify that the stroke of the pushers, or fingers, is set properly according to the joined length of the shells.

    Also check that the raceway is in good condition.

    Failure to separate.

    If the caps and bodies fail to separate, check the vacuum.

    On most capsule fillers, the gauge should read somewhere between 15 and 18 inches mercury.

    You may also need to adjust the gap between the machine's cap segments and body segments.

    Check the timing of the solenoid valve and how well the segments' holes align with the raceway fingers.

    Check the filter bag and clean it periodically.


    Dented capsules

    Dents can form on the dome of the cap and/or body for a variety of reasons.

    One cause is improper setup that leads to the machine applying excessive pressure.

    To determine the correct setting, manually lock 20 capsules together and measure their lengths.

    Next, find the mean value and adjust the machine to that value with the help of a tie rod.

    Another reason for dented capsules is overfilling.

    To correct this, weigh 20 filled capsules. The average weight should not exceed the specified volume of the capsules you're using. If it does, consider using larger capsules.


    This defect occurs when the cap and body misalign and the capsule body splits and a portion of it covers the cap.

    To eliminate this defect, make sure all the capsules are perfectly round.

    Also check the alignment of the cap and body bushings, or segments, using a gauge designed for that purpose.

    The environmental conditions in the filling room can also contribute to this problem.

    If you must stop the machine for more than 30 minutes, protect the capsule shells from direct exposure to the environment.


    If the capsules open or elongate after filling, it's likely due to excessive locking pressure or overfilling.

    It's also possible that the locking mechanism is weak, but that's a defect rarely seen in capsules supplied by reputable manufacturers.


    Check your storage conditions. When capsules lose moisture, often due to poor storage practices, they become brittle.

    The threshold is approximately 12.5 percent moisture.

    Anything less will likely lead to brittleness. Filled capsules that include a hygroscopic active or excipient can also cause brittleness.

    Capsules made from HPMC are less likely to become brittle.

    19.11. Do you need special training to operate the capsule filling machine?

    Yes, you must have special training to operate the capsule filling machine.

    Your supplier may provide the best way to train you and other workers in handling the capsule filling machine.

    This also includes how to clean and properly maintain the machine.

    19.12. How to choose a capsule filling machine?

    capsule filling machine-12

    You can select the capsule filling device by viewing the specific specifications.

    Some technical specifications include:

    • Machine size based on machine size and weight

    The degree of automation of the machine can be manual, semi-automatic, and fully automatic.

    • Machine speed will depend to a large extent on the level of automation.
