Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical equipment, and particularly to a coating equipment with humidity feedback and automatic dehumidification. Background Art

[0002] In the pharmaceutical industry, drug coating is a crucial process step. Coating can not only improve the appearance and taste of drugs, but also enhance the stability of drugs, control the drug release rate, and mask the unpleasant odor of drugs. However, a key problem often encountered in the drug coating process is humidity control.

[0003] During the coating process, the surface of drug particles is prone to adsorb moisture in the air, forming a thin water film. This water film will not only affect the adhesion and uniformity of the coating material, but may also cause cracking and peeling of the coating layer, and even lead to drug deterioration. Therefore, maintaining a dry coating environment is crucial for ensuring coating quality. Traditional coating equipment usually adopts passive dehumidification methods. For example, in the invention patent document with the patent publication number CN116672262A, desiccants are used or natural ventilation is adopted to reduce the humidity inside the equipment. However, these methods have obvious limitations. The desiccants need to be replaced regularly, which not only increases the operation cost, but also the dehumidification effect is unstable. Natural ventilation is greatly affected by the external environmental humidity and cannot effectively control the humidity level inside the equipment.

[0004] In addition, traditional coating equipment often lacks a humidity feedback mechanism during the coating process. Operators cannot understand the humidity status inside the equipment in real time, so they cannot adjust the dehumidification strategy in time to meet the requirements of different drug coatings. This results in difficult stable control of coating quality and large differences between batches.

[0005] In view of the above problems, it is necessary to develop a new type of coating equipment that can automatically monitor and adjust the humidity level inside the equipment to ensure that the coating process is carried out in a dry environment. Summary of the Invention
