Gelatin capsules are widely used in the pharmaceutical and nutraceutical industries as a convenient and efficient way to encapsulate various substances. These capsules are composed of two main components: the body and the cap, which are made from gelatin derived from animal sources. In this blog post, Wecaps will delve into the intricate manufacturing process of empty hard gelatin capsules.
Manufacturing Process of empty hard gelatin capsules for sale
1. Raw Material Selection:
The first step in the manufacturing process is the careful selection of high-quality raw materials. Gelatin, the primary ingredient, is sourced from bovine. The gelatin must meet strict quality standards to ensure the capsules' safety and efficacy. Other additives, such as plasticizers and colorants, are also chosen based on their compatibility with gelatin and regulatory requirements.
2. Gelatin Preparation:
Once the raw gelatin is obtained, it undergoes a series of processing steps to transform it into a suitable form for capsule production. The gelatin is first cleaned to remove impurities and then subjected to a controlled heating and cooling process known as the gelatinization process. This process ensures the gelatin's proper viscosity and gel strength.
3. Capsule Formation:
The gelatin is now ready for the capsule formation process. In this step, two gelatin ribbons are simultaneously formed by pouring the gelatin solution onto rotating drums. These drums have pin bars that create indentations on the gelatin ribbons, forming the capsule bodies and caps. The ribbons are then cooled and solidified, and excess gelatin is trimmed off to obtain uniform-sized capsules. Wecaps has adopted the latest automatic capsule production line.
4. Drying and Conditioning:
After the capsule formation, the capsules undergo a drying process to remove excess moisture. This step is crucial to prevent the capsules from sticking together and to ensure their stability during storage. The drying process involves subjecting the capsules to controlled temperature and humidity conditions until they reach the desired moisture content. Following drying, the capsules are conditioned to achieve optimal hardness and moisture equilibrium.
5. Quality Control:
Throughout the manufacturing process, rigorous quality control measures are implemented to ensure the capsules meet the required standards. Various tests, including visual inspection, weight variation, disintegration, and dissolution tests, are conducted to assess the capsules' physical and chemical properties.
Wecaps empty gelatin capsule production center has a complete quality management system and sufficient QA and QC technicians, and all capsule production is under control. The factories and workshops are designed and constructed in strict accordance with GMP standards and are equipped with fully enclosed central air-conditioning to ensure clean capsule production with constant temperature and humidity.
6. Packaging and Storage:
Once the capsules pass the quality control tests, they are ready for packaging. The capsules are typically packed in blister packs or bulk containers, depending on the intended use. Proper labeling and documentation are essential to provide information about the product, including batch numbers, expiry dates, and dosage instructions. The packaged capsules are then stored in controlled environments to maintain their quality until they reach the end-users.
Every stage of the manufacturing process of the empty hard gelatin capsules supplied by Wecaps is closely monitored and strict quality control measures are followed to ensure the production of the highest quality capsules you can trust.
