Pollen microwave sterilization equipment - its sterilization principle includes not only thermal effects, but also photochemical effects, electronic conjugation effects, and magnetic conjugation effects, which have trauma and sterilization effects on bacteria, achieving the goal of complete sterilization. At the same time, it can achieve the purpose of drying, and has little damage to the effective components of pine pollen. It has the advantages of cleanliness, hygiene, safety, and speed.

Two physical methods, microwave sterilization and irradiation sterilization, were applied to study the sterilization of microorganisms in pollen. The results showed that the sterilization efficiency of Escherichia coli was greater than 90%, and it could significantly reduce the total number of bacteria and mold in pollen. The effects of two sterilization methods on the main nutrients and active ingredients in pine pollen are as follows: irradiation sterilization has a greater impact on vitamin C and catalase, while microwave sterilization has little effect.

The advantages of microwave sterilization equipment are:
1. Short time, fast speed, and even heating.
2. Thoroughly sterilized, and processes such as drying, sterilization, insecticide, and mold prevention can be carried out simultaneously.
3. The product quality is good. It can greatly maintain the nutritional content of the material, provide good sensory experience and taste, and extend the shelf life and freshness of the material.
4. The equipment is simple, the technology is advanced, it is easy to control, it saves space, saves energy, and improves working conditions.
