In drug production, in order to ensure the uniformity and good fluidity of drugs, raw materials are often made into particles using certain methods(Pills, capsules, tablets). By utilizing the thermal and non thermal effects of microwaves, low-temperature drying and sterilization treatment are carried out. Microwave energy is directly radiated into the medicine, causing the internal temperature of the medicine to rise, generating pressure and accelerating the transfer of confined water molecules. The water in the treated item gradually evaporates outward, and at this time, dehumidification is carried out in the microwave equipment to remove the evaporated water. The use of microwave drying to process drugs not only greatly improves product quality, but also greatly shortens drying time and saves a lot of energy, with significant economic benefits.
In addition, microwaves can dry, dehydrate, disinfect, sterilize, kill insects, and prevent mold on various Chinese and Western medicines and medicinal materials. It can greatly facilitate the storage and preservation of drugs and raw materials by manufacturers
