Description

Technical Field

[0002] At present, in the pharmaceutical production industry, most common microwave drying processes use high-voltage transformers or high-voltage power supplies to start microwave tubes, which require many microwave power supplies, generally 90-110. Ten microwave power supplies are installed side by side on each section of the microwave dryer. The microwave power supply of the microwave dryer is prone to heat up during operation. When the temperature exceeds 50 degrees Celsius, the protection program is activated, resulting in power reduction or shutdown. The microwave must be cooled before it can be put back into use. In addition, in the pharmaceutical production process, medicinal talcum powder or rework powder is added. Therefore, high temperature and dust will be generated during the drying process. In particular, the volatile matter of the extract (oil mist) during the drying process of concentrated pills enters the microwave high-voltage power supply, shortening the service life of electrical components and unstable operating power, resulting in uneven dryness and wetness of the material to be dried. In addition, the electrical components are frequently overhauled, and the maintenance cost is high, which increases the production cost. Summary of the invention

[0003] The purpose of the present invention is to provide a microwave high-voltage power supply cooling system capable of avoiding high temperature, dust and volatiles, improving the stability of the operating power of the microwave dryer, improving the quality and yield of semi-finished products, and increasing the service life of electrical components.
