Generally speaking, soft capsules can be divided into two methods of dropping method and molding method. For the molding method, the glue of the capsule to be prepared is mainly prepared, and then the gelatin is put into distilled water according to the formulation of the capsule material. After soaking, the gelatin will expand and wait until the gelatin expands to melt before the formal process of making the soft capsule. It is of course necessary to add other materials together for uniform mixing before production;
In the second step, the film is still made. After removing the prepared capsule glue, we apply it evenly on the surface of the flat board. The thickness should be uniform and then directly used at a temperature of about 90 °C. When heated, a soft film having a certain elasticity and toughness is formed after the moisture on the surface of the board is evaporated.
After the zui is the process of pressing the soft capsule, which can be directly pressed by the pelletizing die in small batch production; in the case of mass production, the automatic rotary rolling bag machine is usually used for production.
In the following, we will talk about the dropping method. The method of dropping the soft capsule mainly refers to the process of preparing the soft capsule by the dropping machine. At the same time of making the soft capsule, it is also necessary to pay attention to the viscosity and formula of the glue and The temperature and density of all added solutions, the subsequent steps are similar to the molding method but there are still many differences
