Microwave drying and sterilization is a common disinfection method. Microwave drying uses the energy of microwave radiation to increase the internal vibration of moisture molecules, thereby evaporating the moisture in the items. This heating process can lead to the death of microorganisms, thereby achieving a sterilization effect.

Microwave drying and sterilization has the following advantages:

1. Highly efficient sterilization: Microwave radiation can heat food to high temperatures in a short period of time, thereby quickly killing microorganisms, including bacteria, viruses and fungi.

2. Uniform heating: Microwave drying can achieve uniform heating of the inside and outside of food, avoiding the problem of uneven temperature that may occur in traditional drying methods.

3. Retain nutrients: Compared with other heating methods, microwave drying can better retain the nutrients in items because it takes a shorter heating time and the energy transfer is more efficient.

4. Energy saving and environmental protection: Microwave heating is an energy-efficient heating method. Compared with traditional hot air or solar drying methods, microwave drying can save energy.
