Considerations in Capsule Filling Process

In the process of filling empty capsules, there are factors that you need to take into consideration.

The factors that you need to consider include:

Hard gelatin capsule content

Hard gelatin capsules content

· Types of Formulations to Fill in Capsules

You can enclose different types of formulations inside an empty capsule such as granules or blends, and coated pellets.

Additionally, you may enclose other dosage forms including tablets, smaller capsules, micro-tablets, and different combinations of these forms.

Powders, non-aqueous liquids, granules, and thermosetting formulations are also suitable formulations to fill in capsules.

Apart from that, you can enclose liquids on a condition that the capsule is not soluble in the formulation liquid.

Capsules with high moisture content have a tendency of losing the water content hence becoming brittle.

You can include ingredients such as plasticizers and Hydroxypropyl methylcellulose to make the capsules resistant to dehydration.

Furthermore, you can opt for the capsules that have low moisture content.

Finally, you should not use fillers with reactive aldehydes as they will lead to cross-linking effect, especially on gelatin.

Cross-linking effect usually results in very low rates of capsule solubility.

· Sizes of Capsules and Fill Weight

You can decide on the right capsule size and fill weight depending on the formulation and the dose requirement.

With the information on the contentment formulation and dosage weight, you can easily determine the capsule size.

The density of the mixture to fill and the volume of the capsule will determine the overall weight of the capsule.

For instance, in granulate and powder mixtures, the tapped density can assist in determining the capsule size.

Bulk density of pellets and micro-pellets will also assist you in determining the respective capsule size and fill weight.

The process begins with the empty capsules moving from the capsule hopper through the vacuum system.

Step Two: Opening the Empty Capsules

The vacuum system is also responsible for separating the caps from the body of the empty capsules.

Since the empty capsules are in the right angle from the automatic orientation, it moves to the filling stage.

The caps will move to a different location where they will await completion of the filling process of the body.

Step Three: Actual Filling Process of the Empty Capsules

Once at the filling station, the dosing disc begins rotating continuously in a circular manner depending on the set speed.

The dosing plate rotates under the powder hopper and allows the powder to flow directly into every hole.

The tamping pins then compress and compacts the powder into the hole creating more space in the hole.

After that, the hole rotates and more powder flows into the hole and a second tamping pin compresses it.

The process continues with further filling and tamping until the hole reaches the last tamping number five.

The machine will then release the compact powder through the dosing plate and into the body of the empty capsule.

To ensure the filling process is consistent and smooth, the machine has to scrap off the excess powder.

After that, the body of the capsules are now full and it moves to the next stage.

Step Four: Covering or Sealing the Capsules

At this point, the rotary turret will move the full body of the capsules to the block that contains the capsule caps.

The rotary turret also ensures that the excess pellets and powders move back to the filling material hopper.

The machine employs a continuous motion in closing action of the capsules where it places the caps on the body.

Step Five: Ejecting the Full Capsules

Once the capsules are complete with the body, filling material (powder) and caps in place the machine automatically ejects.

It can either go through the capsule polishing machine with a sorter and metal detectors.

At this stage, the machine will sort the capsules out and eliminate the capsules with any form of defect.

· How to Fill Softgel Capsule with Encapsulation Machine

The soft gelatin encapsulation process follows the following steps:

Step One: Preparation of Gelatin

First, you need to have the right gelatin formulation which usually consists of gelatin, plasticizers, opacifiers and water.

The gelatin forms the main shell of the capsule and it has to be strong with the right formulations.

Mix all the ingredients in the melting tank for thorough blending, heating and stirring to form a thick syrup.

The thick syrup then flows through the spreader box, cooling drum, and die roller system.

In each of these stages, the machine will work in accordance with the programming parameters from the control unit.

Step Two: Preparation of the Filling Material

The filling material can either be in the form of a liquid, suspension or a semisolid.

It can take the form of an oil base depending on the capsule requirements.

In this process, you may need to use a hammer mill, fluid bed dryers or granulators and a processing tank.

Mix all the ingredients in the processing tank and thoroughly heat and stir to form a homogenous filling material.

The filling material will then flow to the injection wedge from the filling material hopper.

Step Three: Actual Soft Gelatin Encapsulation Process

This is the stage where the soft gelatin and the filling material come together.

The two soft gelatin ribbons move to the rotating die roller system and create a very unique capsule shape.

As that continues, the machine also feeds the gelatin ribbons with the filling material within the die rolls.

The gelatin ribbon encapsulates the filling material and forms a complete capsule.

The shape of the capsules will depend on the die roll cavities.

After that, the machine will cut the soft gelatin capsules into individual pieces.

The brush and the stripper rolls remove the capsules that may stick on the die rolls and gelatin web respectively.

The capsules will then move from the machine through the discharge chute on a conveyor belt for further processing.

Step Four: Further Processing

The Softgel capsules will go through the process of drying, cleaning, and sorting.

First, the conveyor belt moves the soft gelatin capsules to the tumble dryer.

After that, you will load the soft gelatin capsule on tumble trays and straight to the drying tunnels.

You will allow them to stay for a while depending on the drying parameters.

After which you will move the dry soft gelatin capsules to the sorting machine to check on the capsule quality.

Softgel encapsulation process

 Softgel encapsulation process

Step One: Preparation Stage

First you will collect all the ingredients for making gelatin and mix them in the gelatin melting tank.

As soon as you power the machine on, the gelatin mixing tank will heat and mix the ingredients thoroughly.

It will form a uniform mixture of molten gelatin or molten syrup.

You will then allow the syrup to flow to the spreader box which will spread the syrup on the cooling drum.

The cooling drum will cool the hot syrup and lead to the formation of a flat syrup you can refer to as a ribbon.

At the same time, you will prepare the filling material and pour the filling material into the hopper or material tank.

As soon as the gelatin and the filling materials are ready, the machine will begin the process of encapsulation.

Step Two: Actual Encapsulation Process

At this stage, the machine will push the ribbon through tooling system.

As that continues, the lubrication system will apply lubricant oil on both sides of the ribbon and tighten the ribbon.

You should note that ate very point, there will be two ribbons coming from opposite sides.

As that happens, the fill material will move from the hopper into the injection wedge.

It will go through tubes with the help of a force from the injection pump.

The two rollers will, therefore, feed the gelatin ribbons into the die system.

The ribbon from the left and the ribbon from the right will meet at the rotating die system.

The injection wedge will release the filling material at the same time and meet the ribbons at one particular place.

As the two dies rotate, it will cut and then hermetically seal the gelatin ribbons thus forming Softgel capsules.

Step Three: Further Processing

After the encapsulation process, you have to pass the soft gelatin capsules through other processes.

This includes:

i. Drying the soft gelatin capsules to remove excess moisture from the capsules.

ii. Sorting the capsules to eliminate the ones that have defects.

27. How does Dosator Capsule Filler Work?

The following is a step by step guide on how the dosator machine works.

Dosator capsule filling machine

Dosator capsule filling machine

Step One: Powering the Machine

First, you need to prepare all the ingredients that you need for the filling of the capsules.

After that, you will ensure that the machine is functioning properly before powering it on.

The dosator will automatically move to the powder bed.

It will force the powder to flow through and fill the tip of the dosator which has a cavity.

The dosator plunger will determine the size of the cavity at the tip of the dosator.

Step Two: Filling of the Dosator cavity

The powder will flow into the dosator cavity.

It has a plunger that will compress the powder in the dosator cavity and create more space for more filling material.

During the compression process the powder is locked and in the end forms a slug.

The dosator will move from the powder bed as soon as the dosator cavity is full.

Step Three: Doctoring Dosator Tip

This is the point where you will ensure that the tip of the dosator does not have any powder residues.

You can do this by doctoring the tip in an effort to remove the excess powder from the tip.

Step Four; Opening the Empty Capsules

During the filling process of the powder into the dosator, the machine loads the empty capsules in the empty trays.

The capsule trays will move the filling capsules to the filling station.

The machine will separate the caps from the bodies after which it positions it in readiness for filling purposes.

The vacuum system of the dosator filler machine assists in the process of separating the caps from the body.

Step Five: Actual Filling Process

The machine will rotate and change the position of the dosator pins.

The pin of the dosator will move to the point where the dosator pin is.

At the same time, the empty dosator will move to the side of the powder bed.

The simultaneous movement of the dosator pins plunges one side into the powder and the other close to the capsule.

The tip above the empty capsule injects the powder into the empty capsules while the other dosator collects powder.

Step Six: Automatic Closing of the Capsule

The machine will move the body with the powder to the station where the caps are waiting.

Through the movement of the turret, the machine will replace the capsule caps automatically.

It will place and lock the capsules in place as it awaits other processes such as polishing and later packaging.

28. How does Tamping Pin Capsule Filler Work?

The working principles of the tamping pin capsule filler machine will go through the following steps:

Step One: Refraction of Capsules for Proper Orientation

First, you need to load the empty capsules into the capsule hopper of the tamping pin capsule fiuller machine.

At the same time, remember to add enough amount of powder into the powder bed using the automatic powder filler.

Power on the machine after doing a thorough inspection that ensures the machine is in proper working condition.

At this point, refraction of the capsules occurs in a bid to orient them in readiness for filling purposes.

The empty capsules will move from the empty hopper straight to the vacuum system.

Step Two: Opening of Empty Capsule

The vacuum system of the machine will remove the caps of the empty capsules from the body.

The capsules will move to the filling stage because the orientation for filling them is perfect.

The machine will move the caps to a different location awaiting the completion of the filling process.

Step Three: Actual Filling Process

The dosing disc will rotate continuously depending on the rotating speed that you had set.

As it rotates over the powder bed, the powder will flow into every hole.

With the help of the tamping pin, the machine creates more space by tamping and compressing the powder.

With enough room for more powder, the dosing disc will continue rotating until it fills to capacity.

After that, the machine releases the slug into the empty capsule through the dosing plate.

It will scrap off the excess powder to ensure that the body of the empty capsule is full.

Step Four: Sealing or Covering the Capsules

The rotary turret of the tamping capsule filler moves the full body of the capsules to the next stage.

This is the point where the machine will cover the body of the capsules with the caps.

The excess powder or filling materials also move back to the hopper of the filling material.

Through continuous motion, the machine is able to cover the body with the caps before discharging it.

Step Five: Ejecting the Capsule

You will allow the capsules to move to the next stage for polishing and later packaging of the capsules.
