    Hygienic Design

    Trouble-Free Operation

    The entire operation of effervescent press machine is controlled through display screen interface which lowers the stress on working personnel.

    4.How will you classify effervescent tablet press?

    Effervescent tablet press machine is divided into two main categories.

    Single Punch Effervescent Tablet Press

    It is known as single station effervescent tablet press, is the simplest machine for manufacturing effervescent tablets and consist of a single die, upper and lower punches.

    Compaction pressure is exerted only by the upper punch while the lower punch remains stationary.

    These machines can be operated by hand or by power. It is portable, lightweight and generally used for small scale manufacturing line like hospitals and research institutions.

    Single Punch Effervescent Tablet Press

    Muti-Punch Effervescent Press

    It is also referred as multi-station effervescent press or rotary press and has a number of tooling devices which moves to compress powder to effervescent tablets.

    It uses double-sided compression provided by accordion like movement of both punches. The output capability depends upon the speed of turret and number of toolings devices on the machine.

    This machine is extremely useful in increasing the production volume and is used in large scale production businesses.

    5.Can you tell about different parts of effervescent tablet press?

    The important components of effervescent tablet press are described below:


    This part of machine is filled with the raw material or powders either manually or automatically and then this channel passes the material to die.



    The purpose of punches is to compress powders into compact shape. There are two kinds of punches in effervescent press machine: upper and lower punch.

    In single punch effervescent press, upper punches moves vertically in and out of die bore while the lower punch remains stationary.

    In rotary press effervescent press both the punches move to compress the powders.


    Die Cavity

    Die part of machine receives the raw material from feeder; compress the powder into tablets of various shapes and sizes.

    Die Cavity

    Cam tracks

    These components direct the motion of punches at different stages of tablet compression.

    Cam tracks

    Compression Turret

    This ensures the proper alignment of upper and lower punch and the production capacity of machine can be increased by rotating turret.

    Compression Turret

    Feeding Unit

    This channel controls the movement of powder between hopper and die.

    Take-off Blade

    This is present in front of feeding unit and moves the effervescent tablets to discharge chute.

    Discharge Shaft

    This is the part where ejected tablets are collected after compression.

    6.What is the working principle of effervescent tablet press?

    The working principle of rotary effervescent tablet press machine is broadly is based on the movement of punches in the die. The high pressure or force exerted by both the punch results in the compaction of powder into effervescent tablets.

    The working of effervescent tablet press is as follows:

    1. First, the powder or raw martial goes from hopper to the die cavity.
    2. Adjustment of lower punch is done to measure the accurate volume of powder. Scrapper is used to get rid of excess material.
    3. The upper punch moves and applies the high force on powder resulting in compression.
    4. The upper punch is raised which causes removal of pressure force.
    5. The lower punch is moved upward to eject the tablet which is moved to discharge chute. The lower punch is moved downward to next cycle.

    7.What are expected failures of effervescent tablet press? How will you solve them?

    Troubleshooting is an integral part of manufacturing process. It is very essential that you know various kinds of problems that occur during production of effervescent tablet and how can you solve them.

    Some common failure and their solution are derailed below:

    Ⅰ.Non-uniform sized Tablets

    Sometimes the effervescent tablets have issues in their compactness. These tablets are of various sizes which causes the rejection of effervescent tablets and their wastage.

    Non-uniform sized Tablets


    This issue is caused by abnormal motion of punches.


    You can resolve this problem by

    Setting the punches to accurate punch depth

    Checking whether effervescent press toolings have the right size.

    Inspecting the working condition of the toolings

    Replacing the old tooling system

    Ⅱ.Reduced Material Flow

    There is low power flow in die channel which causes decrease in compaction and wastage of products.


    This problem is posed due to

    Misalignments of parts and usage of old parts.


    This problem is fixed by

    Increasing the powder flow and raising the level of feeder.

    Increasing the rate of feeder speed.

    Always use the powder that has uniform particle size.

    Ⅲ.Spilling of Powder

    Sometimes the powder falls or spill from the main body of the machine.


    This predicament is caused by different factors such as

    Rapid flow of materials inside the feeder

    Improper level of frame

    High speed of feeder unit


    This problem of spillage is solved by

    Fixing the speed of feeder

    Decreasing the rate at which material is flowed into the feeder.

    Fixing the level of frame

    Ⅳ.Freezing of Lower Punches

    Sometimes the lower punches get struck and you have to use some effort to move them.

    Freezing of Lower Punches


    Failure to properly maintain cleaning schedule causes sticking of lower punches.


    To resolve this problem

    You should thoroughly clean the tip and socket area of punches. This will remove the upsurge of material.

    You should always properly follow the cleaning schedule to ascertain that your machine is in proper working condition.

    Ⅴ.Abnormal Vibration

    Sometimes you hear abnormal ticking sounds or feel uncharacteristic vibrations coming from your machines. These abnormal sounds disrupt the manufacturing process.


    These strange noises or vibrations are because of wobbly working parts.


    This issue is fixed by

    Fastening the loose nuts and screws

    Greasing the components of machines

    Checking mis-align parts and then properly align them.


    Capping is the breakage of effervescent tablets and removal of top or bottom part. The air trapped between powder particles causes decreasing in bonding capability and tensile strength of effervescent tablets that result in capping.



    This problem arises due to

    High punch penetration

    Fast rotation of turret


    This issue is solved by

    Reducing punch penetration which allow decrease in air flow

    Decreasing turret speed

    8.What are buying considerations of effervescent tablet press?
