A Comprehensive Guide To A Liquid Capsule Filling Machine

The pharmaceutical industry is growing rapidly due to the new developments in advanced medical equipment and effective medicines for diseases. With these advancements, tablets, capsules, and other medications can be manufactured quickly and delivered to patients in less time. The process has become fast and effective as efficient machines and tools perform most of the work.

Nowadays, capsules required to treat harmful diseases are manufactured through a liquid capsule-filling machine that helps in the intact sealing and strong manufacturing of the capsules. As these machines use high-tech systems and mechanisms, the production and packaging process takes little time. These machines have tremendously helped in speeding up the production process.

The working of these machines involves different types of processes and mechanisms that are performed step by step. After every completed step, the capsule moves to the next part of the machine to convert into the final product. One can understand how these machines are effective in producing a large number of capsules through the guide given below, which explains their working and the benefits:

The Machine Uses The Best Filling Techniques And PLC Control System To Ensure The Best Quality 

The working mechanism of the liquid filling machine is simple. The first step in manufacturing a capsule is filling it with a liquid with medicinal properties for curing diseases. For this purpose, the machine uses a high-accuracy injecting system that ensures that most of the space inside the capsule is filled with the required liquid.

During the filling and injecting process, the machine uses a mechanism that tests the outer cover of the capsule. This testing helps in avoiding the issue of leakage in capsules. Due to this, not a single drop of liquid gets wasted, and the fluid gets filled in the capsules. The machine has a vacuum positioning and separation mechanism that helps load 99.5 percent of the liquid inside the capsule.

The filling cabinet is fixed in place, and other parts move to complete the process of filling. The machine has a PLC control system that helps with the effective monitoring of the filling and injecting techniques. The system has alarms that give instant information about any issue in the process, like a material shortage. The insinuating and filling system fills the capsule with a precise amount of liquid in a set period without much human intervention.

The Machine Uses Advance Mechanism For Strong Sealing and Heat Preservation In The Capsule 

After filling the capsule with liquid, the next step is to seal it so that it can transform into the final product. In the sealing system, the machine is equipped with a servo motor that lifts the capsule and drives its upward and downward movements. This system provides a liquid sealing layer to the pill, making it solid and intact.

The following mechanism after sealing the capsule is the heat preservation mechanism. This is performed just after the sealing of the liquid. The system is attached to the liquid sealing tank that helps maintain the viscosity of the capsule glue. The heating and heat preservation system’s function is to provide accurate results in maintaining density.

The drying process is the next and last step in transforming the capsule into a final product. The drying mode uses the free rotation system and vertical suspension to help reduce the drying time of the capsule so that it can be packed and transferred to the appropriate locations. After the drying process, the pills become ready to be used in the pharmaceutical industry

Once these pills are ready, they are used for different purposes, such as suppositories, supplements, oils, etc. There is a wide range of pharmaceutical uses of pills, be it medical or non-medical, due to which one can easily find empty capsules in the market. One must keep in mind that the material of all these capsules has high bioavailability, meaning that they absorb better in the body than medications with lower bioavailability.

Types Of Automatic Capsule Filling Machines 

Understanding the process of capsules getting filled with liquids would have been easy for you. Here you need to know that this process is majorly based upon the use of automatic capsule-filling machines. There are two types of automatic capsule-filling machines, as mentioned below. 

  • Semi Automatic Machine 

A semi-automatic machine combines the work of manual and automatic machines for encapsulation. This type of machine can produce at least 10 to 20 thousand capsules in an hour. The only thing for which you need a person at all times is during the filling process. The filling process is not automatic here and needs to be regularly monitored by a person. 

This type of machine is preferred for granulated or pellets instead of liquids and semi-solids for mass production. But for medium-sized productions, it is a great option for both types of fillings. 

  • Fully Automatic Machine 

A fully automatic machine is one of the greatest upgrades one can have for mass production purposes. It produces anywhere from 12 to 450 thousand capsules in an hour. As it is fully automatic, it is more than twice the cost of a semi-automatic machine, that is it ranges from 30 thousand to 50 thousand dollars. It also has various safety features, such as detecting errors while filling, if the door is left open during the filling process, etc. These features improve the filling capacity, and the waste generated is low all when maintaining a high filling capacity. 


The liquid capsule-filling machine is one of the most significant developments in the pharmaceutical industry. It helps in the fast and effective production of capsules that are highly required in treating patients. It saves a lot of time as most of the processes are performed by machines that run automatically without any human intervention. 

The accuracy of the results is also high, as the system uses powerful mechanisms at every step of the process. The whole manufacturing process is monitored by robust systems that reduce the chance of inaccuracy. In a nutshell, these machines are very effective and reliable for producing capsules.
