Liquid capsule filling are becoming more popular in the market, as they can encapsulate a wide range of liquid forms, including solutions, oils, and suspensions. This capability effectively addresses the challenge of encapsulating drugs and nutrients that are difficult to powder. So nowadays, more and more factories want to buy liquid capsule-filling machine.
However, many people are unfamiliar with liquid capsule filling machine, particularly when it comes to buy from China, such as selecting the right machine, and understanding its operation and maintenance. This article aims to provide not only a quick introduction to the knowledge of liquid capsule filling machines but also to help reduce the costs of trial and error in real-world applications
What is liquid capsule filling and sealing machine
Liquid capsule fillers are used to fill liquid or oily substances into capsule shells and seal them. They are commonly employed for encapsulating liquids, oils, suspensions, essential oils, medications, and nutritional supplements. These machines provide precise control of the liquid injected, ensuring consistent weight for each capsule. This not only enhances production efficiency but also guarantees product quality.
What is the application of liquid capsule filling machine
Pharmaceutical Industry
Liquid Medicines: Liquid capsule fillers are used to encapsulate liquid medications, such as antibiotics, oral liquids, liquid cough syrups, and other similar products.
Special Drugs: These include drugs that require special protection, such as cancer treatments or hormone medications, which are encapsulated to preserve their stability and efficacy.
Health Care Industry
Fish Oil, Vegetable Oil, Vitamins: Liquid capsules are commonly used for oil-based products, as they help maintain the stability of the oils, preventing oxidation.
CBD Oil, Essential Oils, Probiotic Liquids: Liquid capsules protect the active ingredients in these substances from external environmental factors, ensuring their effectiveness.
Cosmetic Industry
Skin Care Oils, Serums: Liquid capsules are ideal for encapsulating highly concentrated skin care products, such as anti-aging serums and other skin oils, preserving their potency and quality.
Two main differences between liquid capsule filling machine and powder capsule filling machine？
Filling material:
Liquid capsule filling machine: mainly used for filling liquid, oil, suspension or viscous substances (such as essential oil, fish oil, etc.). Powder capsule filling machine: it is used to fill solid powder, such as drug powder, nutritional powder, herbal medicine, etc.
Working principle and mechanical structure
The liquid is precisely injected into the capsule using a liquid supply system, while a sealing mechanism ensures that the liquid remains securely contained without leakage. Finally, the capsules undergo a drying process to complete the encapsulation.
Solid powders are pressed into the capsule by tamping pin and dosing disc.
What is the working process of liquid capsule filling machine
Capsule feeding and separate:
The capsule will be faded into segments from capsule hopper, then the capsule head and body will be separated by vacuum at segment.
Liquid filling system:
Use High Precision Ceramic Pumps and servo motor to fill liquid into capsule. It can ensure the filling accuracy within ±2%.
Capsule introduction mechanism
It can transfer the filled capsule into the sealing system in the same direction
Capsule sealing system
The lifting sealing glue table uses a servo motor control system to regulate the process. It also features a sealed glue storage to prevent the glue from evaporating in the air. The double-channel glue wheel and secondary gluing technology enhance the sealing effect, ensuring a more complete and reliable seal.
Finished capsule drying and output
Once sealing is complete, the capsule is transfer into a drying mold. During the air-drying process, the capsule remains in an upright position within the mold and moves in a serpentine back-and-forth motion. Additionally, the mold is designed for easy disassembly and cleaning.
How to choose the model of liquid capsule filling machine
Capacity:
Production capacity is one of the most important items, if you need lab use equipment, then small size model is ok. If for commercial production use, then large capacity models, such as FL-300 or FL-500,300-500 liquid capsule per mins.
Filling product
What will fill into the capsule? Only liquid into capsule, or liquid+tablet into capsule, or liquid+pellet into capsule, or liquid+capsule into capsule. Different products requirement different feeding parts.
Capsule size:
There are many different capsule size, from 00size to 5size, also elongated capsule and safety capsules.
Operation and cleaning
Easy and automatic operation,it can save labor cost. Batch to batch, easy cleaning is also vital important,otherwise it will take too much time for changeover and cleaning.
Cost:
You can not only consider the machine cost, also need to check the landing cost(packing,delivery tax ,customs etc), the service cost,spare parts cost. When you are waiting for long time for parts or engineer to come, it is also a waste of time and money. At Fillitechs, we provide 7*24hours online service and engineer to visit one or two times per year to support customer
10 critical parts need to be cleaned between different batch
Capsule hopper
The empty capsule are loaded into the hopper
Capsule guiding parts
Ensure the capsule guiding at the same directly automatcly.
Segments:
it is used for open the capsule before liquid filling and close the capsule after filling.
Liquid hopper:
Liquid material will transfer into the capsule from the hopper
Ceramic pumps
For fill liquid into capsule, make sure the filling weight is accuracy
Filled Capsule transfer plate
It can transfer the capsule into next step, waiting for guiding.
Capsule tubes and rollers
Ensure the filled capsule automatic guiding, and go to the sealing system.
Chain plates and guards of capsule sealing
The capsule stay in the plates and sealing safety
Capsule drying parts
It can keep the capsule stabley during drying
Finished capsule ejection hopper:
It used for keep the final capsules
