This document summarizes the production processes for soft gelatin capsules and hard capsules. For soft gelatin capsules, the key steps are: (1) gelatin preparation by melting and mixing gelatin with plasticizers, (2) encapsulation using rotary die or plate processes to fill gelatin ribbons with liquid or paste, and (3) drying the capsules to reduce moisture content. For hard capsules, the main steps are: (1) dipping pins in gelatin solution to form shells, (2) drying the shells, (3) selecting capsule size, and (4) filling shells using manual or automatic machines.
