Why microwave dryer can be used for insect killing and sterilizing of Chinese medicinal materials?

Currently, microwave medicinal material dryers are mainly used for the secondary drying, insect killing and sterilizing of Chinese medicinal materials, which are the most effective. To prevent mildew and decay, most farmers use sulfur soaking and drying or sulfur burning and airtight baking, which can easily lead to excessive sulfur residue. The microwave insect killing equipment for Chinese medicinal materials can kill various molds and insect eggs in the medicinal materials at low temperatures, maximize the retention of effective pharmaceutical ingredients in the Chinese medicinal materials, and prevent mold and worm damages generated during storage.
