Example Embodiment

[0011] Example 1

[0012] A manufacturing process of enteric-coated plant hollow capsules involves more than one dipping operation in the manufacturing process of the hollow capsules.

[0013] A manufacturing process of enteric-coated plant hollow capsules, including the following steps, (1), preparing a glue solution: take 10-20 parts of cellulose ether, 0.1-0.5 parts of gellan gum, 0.05-0.2 parts of chelating agent, and add 80- Dissolve and dilute in 90 parts of hot water, add appropriate amount of sunscreen as needed, use 120 mesh gauze to filter out impurities, prepare a glue solution, and add it to the glue tank; (2) Use a mold to dip the glue, and then 20-30 Drying at a temperature of ℃ to make the water volatilize; (3), then extend the mold into the glue tank for a second dip in the glue, and then dry it again; (4) Preparation of enteric coating solution: take the enteric coating 10-20 parts of coating powder, 2-4 parts of plasticizer, add 75-85 parts of organic solvent to ...

Abstract

The invention belongs to the field of medicines, and in particular relates to a process for manufacturing an enteric plant hollow capsule. According to the process for manufacturing the enteric plant hollow capsule, more than one time of glue dipping operation is performed in the process of manufacturing a plant hollow capsule frame. The manufacturing process is a simple method, can be used for improving the baking efficiency of the plant hollow capsule frame by multiple baking operations through multiple times of glue dipping on the premise that a baking device is not lengthened, basis is laid to drying enteric coating in a subsequent process, and the production speed of the enteric plant hollow capsule can be improved.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a manufacturing process of an enteric-coated vegetable hollow capsule. Background technique [0002] Enteric-coated hollow capsule means that the capsule is insoluble in gastric juice, but can disintegrate or dissolve in intestinal juice to release the drug in the capsule. The hollow capsule is the main auxiliary material for processing drug capsule preparations. The currently used enteric-coated hollow capsule is made of gelatin. Forming and then coating the outer surface with a gastric acid-resistant coating material. However, the processing of capsules requires multi-step operations, and the operations are cumbersome. Pharmaceutical gelatin is a high-grade rubber product that is fat-free and high-protein and can be easily absorbed by the human body through complex physical and chemical treatments. It has physical characteristics such as high viscosity, high freezing force ...
