Shiitake mushrooms and fungus are common edible fungi, which usually require sterilization during food processing to ensure food safety and shelf life. The working principle of microwave sterilization equipment is to generate microwave radiation and deliver it to edible fungus samples. Microwave radiation can quickly increase the temperature of edible fungus samples, thereby killing bacteria and other microorganisms. Microwave sterilization equipment usually has the following characteristics:

1. Rapid sterilization: Microwave sterilization equipment can heat edible fungus samples to high temperatures in a short time, thereby quickly killing the microorganisms in them.

2. Uniform heating: Microwave sterilization equipment can uniformly transmit microwave radiation to edible fungus samples, ensuring that the entire sample is heated evenly, thereby achieving better sterilization effects.

3. Retain nutrients: During the sterilization process, microwave sterilization equipment can reduce the damage to the nutritional components of edible fungi due to its short action time, thereby better retaining its nutritional value.
