Without a reliable soft gel encapsulation machine, manufacturers would face significant challenges in producing the high-quality softgels that meet industry standards.
What is the Process of Encapsulation for Soft Gelatin Capsules?
The encapsulation process for soft gelatin capsules is a complex, multi-stage operation that requires both precision and consistency to achieve a high-quality product. The process typically starts with the preparation of the gelatin solution, where gelatin, water, glycerin, and sometimes colorants or flavorings are mixed together in specialized gelatin melting tanks. This mixture is then heated until it reaches a uniform consistency, making it suitable for the formation of the capsule shell.
Once the gelatin is ready, the soft gelatin encapsulation machine begins the actual encapsulation process. The gelatin is formed into two ribbons that feed into the machine’s die roll system. Meanwhile, the fill material (which could be an oil, liquid, or suspension) is prepared in a separate system. This fill material is injected between the two gelatin ribbons as they pass through the soft gel encapsulation machine, which then seals the ribbons around the fill to form individual softgel capsules.
After the capsules are formed, they move through a drying process, typically involving tumble dryers and drying tunnels, to remove any excess moisture. This drying step is crucial for ensuring that the capsules maintain their shape, structure, and stability over time. At the end of the process, the capsules are inspected for quality, sorted, and prepared for packaging.
The entire encapsulation process is automated in modern soft gel encapsulation machines, which improves both production speed and product quality. The machines are equipped with features such as micro-lubrication technology and servo-driven motors to ensure smooth operations, preventing problems like capsule sticking or filling inconsistencies.
What are the Differences Between Capsules and Encapsulation?
While the terms “capsules” and “encapsulation” are often used interchangeably, they refer to different aspects of the manufacturing process. A capsule is the final product that encapsulates a specific dosage of a liquid, semi-liquid, or powder form of a drug, supplement, or nutrient. Capsules can be made from gelatin, plant-based alternatives, or other materials and come in a variety of sizes, shapes, and fill types.
On the other hand, encapsulation refers to the actual process of creating these capsules. During encapsulation, the soft gelatin encapsulation machine or soft gel encapsulation machines combine the gelatin shell with the internal fill material. This process involves precision timing and pressure to ensure that the fill material is properly injected between the gelatin sheets and that the gelatin forms a complete, sealed capsule around it.
To put it simply, capsules are the product, and encapsulation is the manufacturing process used to create them. Modern soft gel encapsulation machines use advanced technologies, such as standard capsule filling machines and automated systems, to ensure that both the capsules and the encapsulation process meet strict quality control standards.
