Problems solved by technology

[0004] However, the inherent disadvantages caused by the use of organic solvents or water are becoming more and more obvious, and are gradually not accepted by the pharmaceutical industry
These disadvantages include the evaporation of organic solvents or water, which is very energy-intensive
This significantly increases the cost of coating and inevitably prolongs the operation time

Abstract

The invention discloses vibration release type equipment and a method for preparing coating for powder medicaments. The vibration release type equipment comprises a forming mold. A water cooling system, a vibration system, a blowing system and a heating system are arranged inside the forming mold. The method includes operation steps of (1), preheating the forming mold; (2), spraying coating materials; (3), cooling the forming mold; (4), stripping the coating; (5), picking up the coating. The vibration release type equipment and the method have the advantages that the forming mold with the sprayed coating materials is cooled in a water cooling mode which is a mild cooling mode, and accordingly the vibration release type equipment and the method can bring convenience for stably forming the coating; formed coating films are stripped in a vibration and blowing combined mode, and the vibration release type equipment and the method are high in stripping speed and efficiency.

Description

technical field [0001] The invention relates to a preparation device and a method for coating a vibration-off type powder medicament, and belongs to the technical field of pharmaceutical coating. Background technique [0002] Powdered medicaments are easy to absorb moisture in the air, become damp and deteriorate, and are easy to splash during transportation and use. Therefore, in order to improve the use safety of powdered medicaments and ensure product quality, usually, powdered medicaments need to be coated before leaving the factory , and inject the powder medicament into the coating, the coating can prevent the powder medicament from contacting with the atmosphere, keep it dry, avoid oxidation and moisture absorption deterioration, and can also quantify the medicament according to the coating. [0003] At present, the coating technology of commercially applied solid dosage forms is liquid coating technology. Usually, the mixture of polymer materials, pigments and excip...
