Capsule filling machine knowledge introduction

The capsule filling machine is a key equipment for drug packaging. It is mainly used to fill powder, granules or liquids into empty capsules. It is widely used in the pharmaceutical, health care and food industries.

This article will give you a comprehensive introduction to what a capsule filling machine is, what types it is divided into, how a capsule filling machine works, what the mechanical components are, and the difference between an automatic capsule filling machine and a semi-automatic capsule filling machine. If you are planning to buy a capsule filling machine, I hope this article can provide you with some help.

What is a capsule filling machine?

A capsule filling machine is actually a professional machine used to fill powder and other materials into capsules. Its task is to fill medicines, such as powders, granular pills, liquid medicines, etc., into the capsule according to the gram weight of each capsule you set. According to the degree of automation, it can be divided into three types: manual, semi-automatic and fully automatic.

Comparison of different types of capsule filling machines:

(1) Manual capsule filling machine:

Its characteristic is that it has to be operated manually, so it is more suitable for situations where the production quantity is small.

Its advantages are low cost and simple operation. Ordinary people can get started with a little learning. However, its disadvantages are also obvious. The efficiency is extremely low. Moreover, because it is operated by humans, the filling accuracy is not easy to guarantee. If people are not careful, they may put too much or too little medicine.

(2) Semi-automatic capsule filling machine:

This type of capsule filling machine has some operations completed by the machine. For example, the upper and lower parts of the capsule are separated, and the capsule is sealed at the end. These tasks can be done by the machine.

In this way, its production efficiency is much higher than that of manual operation, and the filling accuracy can be more accurate.

However, it still needs people to help do some things beside it, and it cannot run completely by itself.

(3) Fully automatic capsule filling machine:

It is fully automated. From separating the cap and body of the capsule, to filling the medicine inside, and then sealing the capsule, it is completely automated and does not rely on human participation.

The capsule filling machine has a high production efficiency and can fill tens of thousands of capsules per hour. The filling accuracy is also very high because it has a very precise metering system that can control the dosage error of each capsule to the minimum. It can adapt to several different specifications of capsules. Whether your medicine is granules, liquids, or powders, it can be automatically filled. The operation is also very convenient. The PLC control system and touch screen make it easy to set parameters, monitor operation conditions, and find faults. The entire machine is made of food-grade stainless steel, which complies with GMP specifications, is easy to clean, and can avoid cross-contamination between different medicines.

Working principle of capsule filling machine

Capsule separation:

It will use vacuum or mechanical means to separate the upper part (that is, the cap body) and the lower part (body) of the empty capsule. After separation, the capsule cap remains in the upper mold, and the capsule body is in the lower mold.

Material filling:

Depending on what is to be filled in the capsule (powder, granules, or liquid), different filling methods are used. If it is powder, use a metering disk or screw system to accurately fill it; if it is granules, use a special granule dispenser to fill it; if it is liquid, there is a special liquid filling device to operate it.

Capsule sealing:

Realign the separated capsule cap and capsule body, and then merge them together, so that a complete capsule is ready.

Capsule output:

The filled capsule will automatically come out of the equipment, and then it can enter the next process, such as quality inspection and packaging.

Composition of capsule packaging machinery

Capsule feeding system:

Its function is to continuously send empty capsules to the separation module.

Separation module:

This module is specially used to separate the capsule cap and body, using vacuum or mechanical methods.

Filling system:

Powder filling device: This device can accurately control the filling amount to ensure that the weight of powder in each capsule is the same.

Liquid filling device: It is specially used to fill liquid medicine and can prevent liquid from leaking out.

Particle filling device: It has the function of vibration and distribution, which can make the particles evenly filled into the capsule.

Sealing system:

By applying pressure or rotation, the capsule cap and body are tightly closed together.

Discharge system:

Send the filled capsule out of the equipment, and pick out the unqualified capsules at the same time.

Control system:

It has PLC control and touch screen operation interface, which can set various parameters and monitor the operation of the equipment. If there is a fault, it can be diagnosed quickly.

Application areas of capsule filling machine

Pharmaceutical industry:

It is used to fill various prescription drugs, over-the-counter drugs and dietary supplements.

Health care products industry:

Filling vitamins, minerals, plant extracts, etc. into capsules.

Food industry:

Packaging coffee powder, spice powder and other edible things.

Chemical industry:

It is used to package chemical powders and granules for specific purposes.

Advantages of capsule filling machine

Improve production efficiency: Because it is automated, the production quantity can be greatly increased.

Ensure dosage consistency: Accurate measurement can reduce the waste of drugs or other materials.

Reduce labor costs: It does not require too much manual operation, saving labor costs.

Comply with industry specifications: It complies with international standards such as GMP and can be used in both the pharmaceutical and food industries.

Capsule filling machines are indispensable industrial machinery for the modern pharmaceutical industry and health pill manufacturing. Whether it is a fully automatic capsule filling machine or a manually operated capsule filling machine, there are many options for you to choose from. Choose the machine according to your needs and budget. At the same time, by understanding its working principle and mechanical composition, you can help you choose the right equipment and optimize your production line speed to save you time and labor costs.

From separating capsules, filling drugs, to sealing, capsule filling machines provide a complete set of solutions, making production efficient, accurate, and safe, and creating more value for enterprises.
