Pellet Compressionuses a pellet press machine to convert powders and granules into tablets by compressing them under high pressure.

This leads to the compaction of the powders and granules to make pellets.

Drug layering, on the other hand, is a process comprising of deposition of different drug entity layers.

You will make the layers from different solutions, suspensions, crystals or granules of similar materials.

Suspension or solution layering involves suspension or dissolution of drug particles in different binding liquids.

Powder drug layering involves spraying binder solutions on inert seeds thus following it with addition of powder.

Which Extrusion-Spheronization Process Variable affect Quality of Pellets?

In the process of using the extrusion spheronization machine, you have to control certain variables that affects the quality of pellets.

Here are the main variables that you should control.

· Type of Equipment

There are numerous types of equipment that you can use in the extrusion-spheronization process.

Different types of equipment will produce different results in varying time frames.

· Mixing Time

This is the time it will take the machine to uniformly mix the ingredients to form a homogenous mixture.

You will control the mixing time according to the type of ingredients you are mixing.

· Temperature

In this case, you have to consider the temperature variations in terms of the type of product you are using.

Different products require different temperature ranges which you have to take into proper consideration.

· Fluid Type

You will choose the type of fluid according to the ingredients and the final result you expect of the pellets.

· Fluid Level

You must also measure the right capacity of fluid that you will need in the pellet production process.

The capacity of fluid or the fluid level will depend on the ingredients that you intend to mix.

· Wet Mass Time

This is the time it will take for you to wet the mass ingredients of making different types of pellets.

· Die Diameter

This is the part of the machine that will determine the size of the pellets.

You can control the die diameter of the machine according to the size of the pellets you intend to make.

· Die Length

This is another factor that you need to control in order to determine the size and quantity of pellets you can produce.

· Feed Rate

You can control the speed of delivering or feeding the ingredients in the extrusion spheronization machine.

It will also determine the speed with which the machine can produce the pellets effectively.

How does Pellets Extruder and Spherionizer Work?

In order to operate the extruder-spheronizer machine, you have to have a proper grasp of the working principles.

Here is a step by step guide that you can follow to properly operate an extruder-spheronizer machine.

Extruder section

 Extruder section

Step One: Mixing or Granulation

First, you need to prepare the ingredients that you will need for the extrusion and spheronization process.

You will prepare the ingredients through two different processes known as dry mixing and wet massing.

Dry mixing involves the process of mixing all the ingredients together to form a homogenous mixture.

You will need a granulator machine to assist in the granulation and mixing of all the ingredients.

You must, however, remember to consider all the production variable and maintain them accordingly.

It will assist in doing away with any form of variation that may occur in the process of extrusion and spheronization.

It will also lead to proper and consistent pellets after completing the entire process.

Measure and carefully pour all the ingredients in a granulator machine for proper mixing and granulation.

The machine will automatically stop as soon as you achieve a homogenous mixture over a specific time frame.

After that you will perform wet massing to produce sufficient plastic masses for extrusion purposes.

Step Two: Extrusion

After that, you will obtain the mixture from the granulator and use it in the extrusion process of making the pellets.

In this case, certain factors such as diameter of the extrudate will go a long way in determining the pellet sizes.

For instance, you will need a one-millimeter diameter screen of the extruder to attain a one-millimeter diameter of the sphere.

You should, however, use larger screens that will provide enough room for shrinkage during the drying process.

You will have a machine that has a wide range of diameter of the spheronizer basically between 0.4 mm and 10 mm.

It will lead to the formation of rod-shaped particles of uniform diameters using the wet mass.

After that, the rod-shaped particles will break in similar sizes and their own weights.

The final product will then move to the spheronization phase.

Step Three: Spheronization

Pellets spherionization

Spherionization

A spheronizer machine has circular discs with revolving drive shafts that rotate at very high speeds.

Apart from that, it has a rotating frictional plate has different groove patterns at the bottom of numerous sizes.

The extrudates will fall onto the spheronizer landing on the rotating plate.

The extrudates will cut into different fragments due to interaction of the friction plate and cylindrical granules.

As this continuous, the extrudates will bump on the wall, the plate and against one another thus forming spheres.

It is a gradual process that will eventually lead to the formation of a perfect sphere.

After attaining the right shape and size, you can remove them from the spheronizer and on to the next process.

Step Four: Drying and Coating

Through centrifugal force, the machine will discharge them on to the drying and coating machine.

You will set the temperature and drying time accordingly to achieve the best results.

After that, you will pass it through a coating machine to provide it with the right coating before discharge.

What determines quality of Extrudes from Pellets Extruder and Spherionizer?

There are different factors that determine the quality of extrudes from the pellet extruder and spheronizer.

The main factors that you must pay close attention to include:

i. Ratio of Liquid to Solid Materials

This factor will determine the final mixture of the solid and liquid materials in a bid to make the best pellets.

ii. Size of the Extruder Holes

This factor will determine the final size of the pellets since it determines the diameter of the pellets.

iii. Final Drying

The final drying will determine the quality of the hardness of the pellets.

The two systems that the machines use include the shuttle system and the cascade system.

The shuttle system involves the use of two parallel spheronizers while cascade uses one or more spheronizers.

How does Batch Spheronization compare to Continuous Spheronization?

Batch Spheronization and continuous spheronization are two of the main systems developed for shaping pellets.

Batch spheronization involves a process where the sphere will come out in groups over specific production parameters.

It involves the production of the specific parameters over a particular period without end user interaction.

It delivers the extrudes at specific amounts over a specific amount of time.

Continuous spheronization involves a process where the spheronization machine produces more products continuously.

It does not stop over a particular time but will only stop after completing the entire process or due to user intervention.
