Liquid Filled Hard Capsules

Preparation of empty capsules and liquid fills
The operator loads empty capsules and liquid fills into their hoppers. Capcn-l30 is capable of handling capsule sizes ranging from #00 to #5. Aside from liquids, the equipment can also fill many other materials, such as semi-solids, suspensions, pastes, and waxy substances.

Capsule feeding and separation
During this stage, the empty capsules are rectified and transferred to the segments in the vertical position. When each capsule is fed into the segment pore, they are ready for the next step - separation.

The vacuum system plays a key role in capsule separation. When the capsules are separated, the bodies fall into the bores of the lower segment, while the caps remain in the bores of the upper segment.

Liquid dosing and filling
After separation, the lower segment holding empty capsule bodies moves to the filling station. Liquid fills are pumped into the filling station by a peristaltic pump. The pump enables precise liquid dosing without leaking, dripping or air bubbles.

Capsule closing
Now the lower segment carrying filled capsule bodies rotates to the closing station. As with conventional capsule filling machines, the upper segment is lined up with the lower one. A row of pins pushes the bodies up from the bottom of the lower segment to close the capsules.

Filled capsule transfer
In the above four steps, any capsule that fails to separate or close is rejected by vacuum. In this stage, the closed capsules are pushed out of the segments into the holes of a rotary disc. All segments are then cleaned by vacuum and go back to the first place for the next circle.

Filled capsule sealing
The sealing mechanism is mounted under the slat conveyor. It comprises two sealing rollers, two gelatin bowls, a water tank, and a gelatin tank. By the way, two gelatin bowls and the gelatin tank are equipped with heaters to maintain the temperature of the gelatin.

Sealed capsule drying
The sealed capsules are then moved to the drying carriers from the slat conveyor and transferred into the drying box. The drying box uses filtered indoor air at a constant room temperature to dry the capsules on the carriers.

Raw material melting & coloration
The raw material that meets the acceptance test requirements is brought into the manufacturing area.

Raw material contained in the hopper is automatically weighed in the container.

Now, the weighted material will be shifted from the container to the melting tank.

 Purified water is added to the melting tank before finally starting the melting process.

After initiating the melting, the mixture gets stirred to create a uniform jelly.

In this step, the colorant can be added to the colored capsules.

Capsule molding & cutting
In the capsule production room, the capsule manufacturing machines receive the colored jelly.

The pins are then dipped into the jelly mixture. Molding pins are then shifted to the drying unit.

The drying process will be at a constant temperature and humidity. After the drying process, these are sent to the next section.

Now, the dried caps and bodies are removed from the molding pins.

The caps and bodies will be trimmed to an appropriate length and then pre-locked.

Next, an immediate visual inspection of all the capsules will be done. The light is flashed on the rotating capsules, and the digital images are captured with cameras. Besides, image processing technology is used to detect abnormal shapes.

In the last step, the conformed capsules will be packed into the containers.

Printing, inspection & packaging
Now, the printing of the capsules started for the product identification purpose.

The specified design is printed in the capsules by utilizing the ink and printing machine of the company.

An alternate option can also be used for printing without ink. In this part, you can use the laser printing machine.

Packaged capsules are stored in the product warehouse with controlled temperature and humidity.

Shipping tests & shipment
The companies can do some tests before the shipment of the right capsule products. Capsules are generally tested for dimensions, appearance, moisture content, separation, and more.

Jiangxi Linquan Capsule Co., Ltd. was founded in 1994 and has two production bases with a total area of 106,000㎡ and a building area of 49,000㎡. It is one of the main capsule manufacturers in Jiangxi and Guangxi provinces and a key national capsule production enterprise! There are more than 260 employees, over 60 professional and technical personnel, and 15 foreign trade personnel.

The production workshop follows GMP standards and is sterile, ensuring that every production process is under strict quality control. The workshop trains experienced operators and supervisors to ensure that no pollution sources can enter the workshop.
We have 36 fully automatic capsule production lines with an annual production capacity of up to 30 billion capsules.

The newly upgraded plant-based hollow capsules are made from HPMC, a derivative of plant cellulose. No preservatives are added during production, no ethylene oxide is used for sterilization, and there are no toxic or harmful substances. Gelatin capsules are made from 100% bovine bone raw materials, which have passed CEP certification.

Our products meet special religious, cultural, and dietary needs, effectively avoiding the risk of animal-borne diseases. Compared with traditional gelatin capsules, plant-based hollow capsules have unique advantages such as low water content, strong chemical stability, high toughness, no brittleness, and dissolution that is not affected by pH values.
