    18.What are the Main Components of Full Automatic Capsule Filler Machine?

    There are several parts that comprise the full automatic capsule filler machine,among which the most important components you should know include:

    Capsule Filler Machine

    1.Powder Hopper

    This part is place where you can put various powder or filling materials you want to fill into the capsules.

    It is made of stainless steel that will be easy for your maintenance.

    And normally,the powder hopper locates at the same height with the capsule holder or some different design may higher than the capsule hopper and inside there is the powder sensor that regulates the amount of powder to be filled.

    Powders inside the hopper are driving by the compact feeding mechanism to move forward to the filling station.

    In fact,the powder hopper not only holds the materials but also will make homogeneous mixture of all the powders to be filled to make it move into the next filling station.

    2.Capsule Hopper

    Capsule hopper as its name is a place where all the to be filled empty capsules are stored.

    It not only holds all the empty capsules,but also controls the quantity supply of the empty capsules with the help of the sensors.

    The capsule hopper is made by stainless steel that you will find there are 3 kinds shape of capsule hopper in the market now ,they are cubic shapes of capsule hopper,cylindrical shapes of capsule hopper and conical shapes of capsule hopper.

    3.Capsule Feeding Unit

    Capsule feeding unit stands on the top of the  automatic capsule filling machine that its main function is to control the number of empty capsules running into the filling parts.

    You can adjust the capsule feeding unit as per your actual production requirements.

    Besides,capsules that have defects are not allowed to go through this area to the next feeding unit,it will be blocked here,so you will no worry about the empty capsule defects go into the filling parts.

    4.Capsule Separation Station

    The capsule separation station is as its name to separate the caps and body of the to be filled empty capsules.

    Actually,apart from that it also connect the powder feeding with the powder hopper and the capsule loading with the capsule hopper.

    5.Closed Dosage Device

    Closed Dosage Device

    The closed dosage device is a place where the precise amount of powder dosage goes into the filling hopper to be filled into the empty capsules.

    But also here there is the powder sensor that controls the flowing of the powder,drive the powder to be filled or cut down the excessive amount of powder.

    And during the capsule filling process,you will find powders on the closed dosage device will be derived to move into the filling hopper by the compressed air jet.

    6.Closed Rotary Turret

    This is the main part of the automatic capsule filling machine as it controls the whole capsule filling process.

    The closed rotary turret is a closed design that will get rid of dust,you will no need to worry that dust or particles in the air sticks to the powder due to long time operation.And frequent clean or assembling of the mold may also increase the cost for you.

    Of course,the closed rotary turret also compliant with the GMP requirements.

    7.Mechanical Drive System

    The mechanical drive system is the critical part of the automatic capsule filling machine as it starts all the process and determines all the motions  that include the main drive,motor ,hopper drive and the vacuum drive of the machine.

    It consists of the motor,gear and conveyor which unites to movitates the machine.And also completely closed to get free from dust and avoid other issues led by frequent cleanings.

    In fact,there is the PLC control system who displays the technological elements of the automatic capsule filling machine that regulate the mechanical drive system.

    8.Lubrication System

    The lubrication system of the automatic capsule filling machine is to lubricate the moving parts and the mechanical parts for long-time running then reduce the worn-out.

    At the same time,guarantees the smooth filling process.

    You will no need to use lubrication oil to lubricate the conveyor and the moving parts to decrease the friction between each components,the lubrication system will work automatically to lubricate the filling and powder dosage discs to ensure sufficient ejection.

    19.How Does Automatic Capsule Filler Machine Work?

    Working principle of automatic capsule filler can be divided into :

    .Capsule rectification

    You know that most empty capsules are joined capsules whose caps and bodies are joined together,that is,they need to be rectified before the filling process.

    Capsules are randomly poured into the capsule feeding unit then go through the capsule hopper.

    You will find at the lower part of the capsule hopper there is the spring pieces,when the automatic capsule filling machine starting to work,the capsule delivery plate will reciprocate up and down to make the capsule either enter the holes or stuck by the spring piece.

    After that the capsule delivery plate will move downwards to make the spring piece release the capsules,and the capsules will fall.

    In fact,at this step,the capsules need further rectification as it may be body end downward or cap end downwards when falling.

    Then when the capsules are allowed to fall on a horizontal fork that locates on the center of the capsule,a vertical fork will adjust the direction of these capsules.

    Now the capsule rectification is completed.

    .Separating capsule caps and bodies

    Separating capsule caps and bodies

    When the capsules are rectified,the capsule tray will move to the capsule filling station,here the vacuum divider will raise to make its upper surface near to the lower surface of the lower segment .

    Then the capsules are separated by the vacuum because of the different diameter of the capsule caps and bodies.

    After that,the capsule caps will be stuck to the upper part of the capsule tray and the capsule bodies will go downwards.

    That is when the separation is done ,the caps and bodies will be transferred to their respective stations.

    .Medications Filling

    Capsule Filler

    Here you will find the capsule body will be conveyed to the filling station for filling medication.

    Automatic capsule filling machines use vacuum filling to fill the active ingredients into the capsule.

    Vacuum filling is applicable to all kinds of medication,as there is no mechanical moving and it has little damage to the medication.

    .Waste Capsule Rejection

    During the capsule filling process,you may find some of the capsule bodies may not be separated ,they are wasted products.

    In fact,there are pins inside the automatic capsule filling machine that will pull such capsules out of the mold and blow them into a collection station.

    While the filled capsule bodies and caps are transferred to the next station for locking.

    .Capsule Locking

    The upper and lower capsule tray will rotate together to the locking station at the same time,and simultaneously,the axis line of the upper and lower capsule tray will overlap.

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

    .Capsule Ejection

    Once the filled capsule is locked in place,an ejection device,that is very similar to the capsule rejection device,will eject the locked capsules out of the capsule tray and send them to the outlet.


    When all the capsules are ejected ,the capsule tray will move back to the first station,the capsule rectification station.

    Then tray will automatically cleaned for any powder remains by the compressed air and waste capsule debris are collected at the dust collecting system.

    The above is the whole automatic capsule filler machine working process,though it seems cumbersome,each step may take very short time.

    In fact,with reasonable design of circular structure,automatic capsule filling machine can make these steps proceed simultaneously.

    That is automatic capsule filling machine can fill up to 12k-450k capsules per hour,which will be your best choice if you need large scale capsule production.

    20.What are the Main Parts of Semi-automatic Capsule Filler Machine?

    21.How Does Semi-automatic Capsule Filler Machine Work?

    Semi-automatic capsule filler machine is a combination of both automatic and manual capsule filler machine,you will find its working process can be described as below:

    Loading of Capsules:

    When the machine is in good condition,it will start to load the empty capsules and the filling medication into their respective hoppers.

    Then your operator will have to press the start button to make the machine start to work and key the operation parameters at the touchscreen panel to guide the operation of the semi-automatic capsule filler machine.

    Capsule Separating

    All the empty capsules in the capsule hopper will go through the delivery system of the machine to the round capsule tray.

    Then the upper capsule tray will hold the caps while the bottom tray hold the lower body .

    Your operator will need to manually remove the upper tray while the bottom tray will keep hold the lower body of the empty capsule.

    Then the body will stay intact and moves around the conveyor belt waiting to be filled.

    Filling Capsules

    Then the semi-automatic capsule filler machine will start to fill the medication into the empty capsule body.

    You will find the filling table will place the filling nozzles above the empty capsules and the tray will keep in continuous motion when the filling medication goes into the empty capsule body.

    And through the dosing disk,the filling quantity and speed can be controlled accurately.

    Finally,when all the capsules are filled with medication,the filling nozzle will be retrieved automatically .

    Caps And Bodies Locking

    Your operator will need to place the caps tray directly above the body tray to push the caps locked with the capsule bodies.

    Here your operator may need to apply a little pressure at the compression zone so that the capsule caps can fit onto the body perfectly.

    Then,all the semi-automatic capsule filler machine capsule filling processed completed,you can take the filled capsules out from the machine for further inspection or packaging.

    Then you can fill the medication into the capsule bodies and make them seal off,and forwardly pull the the locking level.

    At this stage,the capsule bodies are at the same level with the filling surface.

    You will have to measure the powder first to make it up to your desired filling weight.

    Of course,the machine can help compress the powder if you need to make the powder more compact.

    Then once the capsules are filled with the filling medications,it will move to the next stage to be locked.

    The part handling the bodies will be pushed back into caps all at one time thus make the capsule locked.

    Then you finished the capsule filling manually and the capsules are arranged over the tray to exit the manual capsule filler to be packed.

    24.Which Equipment Are Needed in Aiding in the Entire Capsule Making More Efficiently?

    A complete capsule filling line is not alone,along with the capsule filler,combined with other equipment that as well play an important role in aiding in the entire capsule making more efficiently.

    A cartoning machine will fully automatically put the capsules in blister into pre-prepared boxes and the instruction manual into the boxes.

    25.What Quality Standards Should the Capsule Filler Comply With?

    To regulate all behaviors, there must be some quality standards or certification documents that capsule filler must meet with.



    GMP or cGMP are two one of the most important standards that all pharmaceutical manufacturers must comply with.

    They both regulate and guarantee the safety and reliability of the capsule filling process.

    That is,they are documents in detail that remark all possible happening behaviors and its respective measurements.

    And prevents and possible contamination.



    ISO stands for International Organization for Standardization, which is an international standard for capsule filling machine.

    Comply with which means not only ensures the machine safety and quality but alos encouraging innovation in the global market.



    CE represents the capsule filler manufacturer or service provider's assurance that the capsule filler complies with the corresponding European Union directive and has completed the corresponding assessment procedure.

    26.What Should You Consider When Choosing Capsule Filler?

    There are factors you should consider when choosing capsule filler to meet your actual production requirements.

    1.Identify the right technology

    Capsule Filler

    That is ,you should not only focus on price or make that your initial consideration when purchasing capsule filler machine .

    In fact,firstly,you should consider what on earth is the best technology for your actual production.

    As in capsule filling,there are lots of technologies on the market now,and each may have various unique advantages,the reason these unique technologies exist may due to these advantages.

    So you have to consider the characteristics of the medication you are going to fill,them compare them with the equipment capabilities.

    Then before making your final purchasing determination,negotiate with your machine suppliers to do some factory tests,see which equipment run most naturally with your medications.

    2.Identify the right vendor

    The most often overlooked you need to consider is the equipment reliability and after sales support.

    For example,when your some parts of your new capsule filling machine crashes for the first time,where can you find the replacement?Or if the OEM parts can be found elsewhere near your area.

    Does the vendor have site support or other kinds of support if you have problems that is difficult for your technician to troubleshoot.

    Does the vendor have an English guide for you to solve the problem more fluently?

    If your problems can’t be solved immediately,how long will it take ?

    In fact,a good vendor should offer wonderous supports through training,after sales service and maintenance assistance.

    A good vendor should be its industry support can be easy accessible and common through the industry.

    3.Identify the right size of equipment

    Optimizing equipment uptime in manufacturing nowadays can be said to be one of the greatest challenges faced by most production leaders.

    While you may spend large efforts to optimize your uptime if the machine size is not correct at first time.

    The size of the equipment determines the production capacity,projected uptime or the changeover time,or you may have to project the appropriate space to hold the machine .

    4.Designed Downtime

    Some companies may not consider the downtime for maintenance that lead to production stagnation because of breakdown.

    In fact,neglecting the downtime may result in more cost than a machine which is regularly maintained.

    27.How to Troubleshoot Common Problems of Automatic Capsule Filler Machines?

    Capsules are easy to fill,but sometimes,things may still go wrong.

    Below you will find some tips on how to troubleshoot these problems:

    First,before filling a capsule hopper with empty capsules,you have to check if the capsules meet your dimensional specifications through checking one representative sample first.Since capsules offered by different manufacturers may vary .

    Secondly,make some adjustments first to your tooling as the tooling may also differ by different vendors.verify your setting and check that if the routine maintenance has been done before the capsule filler start to run.

    Thirdly,get some knowledge that you understand or familiar with the medication or active ingredient to see if they affect the filling.

    Fourthly,you have to check if the environmental condition in the capsule filler room is suitable for filling.The ideal temperature is 22°C ± 2° and the relative humidity is at  40 to 50 percent.

    If the temperature or humidity are beyond that range,you await for some time for the room or filling medication to self acclimate before starting your production.

    Next,you may follow below steps troubleshooting common problems that may happen during the capsule filling process:

    Lumpy or misshapen capsules

    Lumpy or misshapen capsules

    Before loading the empty capsules on the capsule hopper,if you find the capsules are lumps or misshapen,you may check the condition your capsules are transported or stored.Then next time please remain the empty capsules at a temperature between 15° and 30°C and relative humidity between 40 and 65 percent.

    And you also need to not expose the empty capsules directly to light or heat.And not move the capsules from a high-temperature to a low one suddenly.

    Improper rectification

    If your capsules are not oriented properly with cap up and body down,first,you have to verify the stroke of the pushers or fingers are set properly according to the joint length of the shells.

    Pay attention you should not use a plastic container to transport the capsules as plastic can cause an electrostatic charge to develop, hindering rectification.Use stainless steel containers and scoops instead.

    Failure to separate

    You may check the vacuum if the caps and bodies fail to separate.

    Then you may adjust the gap between the machine’s cap segments and body segments.

    Then you may also check the timing of the solenoid valve and if the segments’ hole align with the raceway fingers.

    Another way is checking the filter bag and cleaning it regularly.

    Dented capsules

    Dents of capsules may be found on the cap,body as many reasons.

    One reason may be improper setup that results in the machine applying too much pressure.

    So,to see if the setting is correct,you can do some tests by manually lock 20 capsules together to measure the capsule length.

    Then you may check out the correct parameter and adjust the machine to that parameters through the tie rod.

    In fact,another reason for the dented capsules is overfilling.

    So ,to correct this,you have to weigh 20 filled capsules,whose average weight should not exceed the specific volume of the capsules you are using.If over that ,you may consider use large capsules.



    This kind of problem happens when the cap and body misalign and the capsule split and part of the capsule covers its cap.

    To solve this problem,you have to make sure all the capsules are round.

    Or you can also use a gauge to check if the alignment of the cap and body bushing and segment.

    Besides,the environment condition may also have effect on this problem.Then you may have to stop the machine at least half an hour but protect the capsule shells from direct exposure to the environment.


    If you find your capsules open or elongate after filling,it may be excessive locking pressure or overfilling.

    It may be the locking mechanism is too weak.



    This problem,you have to check your storage conditions.Since when the capsule gets rid of moisture,due to poor storage conditions,they will become brittle.

    Apart from that,the filled capsules that have hygroscopic active or excipient may also lead to brittleness.

    However,capsules that made from HPMC will not likely become brittle easily.

    28.How to Maintain Automatic Capsule Filler Machine?

    Steps for you to maintain the automatic capsule filler machine are as follows:

    Capsule Filler

    (1)When the capsule filler works for a long time,some parts that contact directly with the drug should be cleaned regularly.

    (2)You will have to add appropriate amount of lubricating oil to the transmission mechanism under the working table of the capsule filler to reduce the worn out of the moving parts.

    (3)Add lubricating oil in the main drive drop box when the capsule filler runs for 250-300 hours and check the powder feeding mechanism and replenish lubricating oil.

    (4)The vacuum separator of the vacuum system is to inhale the capsule into the upper and lower modules and separate the cap and body in the capsule filling.

    So if the capsule cap and body can’t be separated,the later filling may be not possible.

    When you find the capsule cap and body separation is not smooth,you should check the gap between the upper plane of the vacuum separator and lower plane od the lower module.

    Then you may need to adjust the position of the vacuum separator, turn the main motor shaft by the handle, make the vacuum separator to rise to the highest position, loosen the adjustment of the machine mesa falls at the ends of the rod lock nut (a left-handed nut, a right-handed nut), and then turn adjusting screw to adjust the height of the vacuum separator, then lock nut and turn the main motor shaft test by the handle until it is right.

    For the vacuum system, you may have to change the circulating water in the circulating bucket once a week to ensure the cleaning of vacuum pump.

    Last,you have to regularly turn on the filter to remove clogged dirt.

    (5)You have to check the tightness of the transmission chain once a week,adjust and remove the grease.

    (6)Regularly check if the axial fan is well-ventilated.

    Make sure the inverter heat dissipation is good.

    If the main engine is stopped due to abnormal conditions in the working process of the frequency converter, the reason for the abnormal conditions should be found according to the display code on the frequency converter, troubleshooting, cutting off the power supply of the frequency converter. After triggering the display to go out, switch on the power supply again and restart the machine.
