For a long time, China's pharmaceutical processing industry has adopted traditional heating and drying methods, such as drying with hot air and far infrared, and sterilization with high temperature and high pressure, cobalt 60. Not only are they low in thermal efficiency, long heating time, and large floor space are not conducive to environmental protection. Microwave in the pharmaceutical industry is mainly used in the drying and sterilization of pills, tablets, powders, granules, Chinese herbal extracts, extracts and various oral liquids, Chinese and Western medicines, and rapid extraction equipment for Chinese medicine. It can be said that the use of microwaves in drying equipment is a major change for the pharmaceutical industry.
Sterilization should be kept under pressure at a high temperature of 120 ° C for 20 to 40 minutes, and the efficacy and nutrients of the drug will be destroyed to some extent. The use of microwave dryer drying, sterilization can fully play the role of microwave drying, sterilization, can solve the drawbacks of traditional heating. With the well-designed pill microwave drying equipment, the processed pills are not cracked, the consistency is good, the originality is maintained, and the shelf life is extended. The 5KW microwave oral sterilization drying equipment produced by Henan Boda Microwave Equipment Co., Ltd. can process more than 5000 oral liquids of 10mL per hour. The sterilization temperature is only about 80 °C, and the time is less than 1 minute. Moreover, the color of the oral liquid is clear, the oral nutrients of the oral liquid are maintained, no precipitation, and the taste is good. The equipment has passed the pharmaceutical GMP certification.
In addition, microwaves enable normal growth and stable genetic propagation of nucleic acid RNA and deoxyribonucleic acid DNA, which are caused by several hydrogen bonds to relax, cleave and recombine, thereby inducing genetic mutations, or chromosomal aberrations or even ruptures. Microwave sterilization drying equipment also has the following two characteristics:
(1) Energy conservation: Conventional thermal sterilization often has heat loss in the environment and equipment, while microwaves directly treat the food, so there is no additional heat loss. In comparison, it can generally save 30-50%.
(2) Uniform and thorough: Conventional thermal sterilization starts from the surface of the material and is then transmitted to the inside through heat conduction. There is an internal and external temperature difference. In order to maintain the flavor of the food and shorten the processing time, the inside of the food does not reach a sufficient temperature to affect the sterilization effect. Since the microwave has a penetrating effect, when the food is processed as a whole, both the surface and the inside are simultaneously acted upon, so the sterilization is uniform and thorough.
Henan Boda Microwave Equipment Co., Ltd. specializes in the microwave drying field, and designs microwave drying equipment for the majority of enterprises.
