Microwave on pills, capsules, tablets described the characteristics of dry sterilization: 
 Traditional pills, capsules, tablets and dry and steam sterilization are used for the tunnel oven, which not only requires a lot of production plants, but also an expensive air-conditioning equipment, consume large amounts of energy, and very long drying time, generally take several hours or several days. Microwave equipment to pills, capsules, tablets drying and sterilization, can reduce labor intensity and improve the quality and guarantee the product of one Emotion. 
 In pharmaceutical production in order to ensure uniformity of drugs and good liquidity, often the raw material made of particles with certain methods (pills, capsules, tablets). The thermal effect of microwave and non-thermal effects, low-temperature drying and sterilization, microwave energy radiated to the drugs, making drugs the internal temperature, resulting in pressure to accelerate the transfer of water molecules are bound, is processed materials in the water gradually outside the evaporation of microwave devices at this time and then pass to the appropriate hot air out of the water will evaporate away. In order to ensure product quality, should be strictly controlled air temperature, humidity and traffic. Microwave drying of drugs not only significantly improve product quality, and will greatly reduce the drying time and save a lot of energy and economic benefits are obvious.
