For a long time, traditional heating drying and sterilization methods have been adopted in the pharmaceutical processing industry in China, such as hot air and far infrared drying, high temperature and high pressure, cobalt 60 and so on. They not only have low thermal efficiency, long heating time and large area, but also are not conducive to environmental protection. Microwave equipment in the pharmaceutical industry is mainly used in drying and sterilizing of pills, tablets, powder, granules, extracts of traditional Chinese medicine, extracts and various oral liquids, Chinese and Western medicines, and rapid extraction equipment of traditional Chinese medicine. It can be said that the use of microwave in drying equipment is a major change for the pharmaceutical industry.
Sterilization should be kept for 20-40 minutes under high pressure and 120 ~C, and the pharmacodynamics and nutritional components of drugs will be destroyed to a certain extent. The use of microwave dryer drying, sterilization can give full play to microwave drying, sterilization characteristics, can solve the drawbacks of traditional heating. With the carefully designed microwave drying equipment, the processed pills do not crack, have good consistency, maintain the original quality and prolong the shelf life. The 5KW microwave oral sterilization drying equipment manufactured by Henan Microwave Equipment Co., Ltd. can process more than 5000 oral liquid of 10mL per hour. Its sterilization temperature is only about 80 C, and the time is less than 1 minute. It not only meets the hygienic standard, but also has clear color, maintains the original nutrient composition, no precipitation and good taste of oral liquid. The equipment has passed GMP certification. In addition, microwave can make bacteria grow normally and reproduce steadily. Nucleic acid RNA and deoxyribonucleic acid DNA are relaxed, broken and recombined by several hydrogen bonds, which can induce genetic mutation or chromosome aberration or even breakage. Microwave sterilization and drying equipment also has the following two characteristics:
(1) Energy saving: conventional thermal sterilization often has heat loss in the environment and equipment, while microwave is directly used to treat food, so there is no additional heat loss. In comparison, it can generally save 30-50% of electricity.
(2) Uniform and thorough: Conventional thermal sterilization starts from the surface of the material and then transmits through heat conduction to the interior. There is a temperature difference between inside and outside. In order to maintain the flavor of food and shorten the processing time, the sterilization effect is often affected by insufficient temperature inside the food. Because microwave has penetrating effect, when food is treated as a whole, both surface and interior are affected at the same time, so sterilization is uniform and thorough.
