Introduction to Microwave Sterilization Equipment:
Microwave sterilization is an extension of the function of microwave heating technology, manifested by the interaction between microwave and the basic unit of organisms and their components - cells, resulting in changes and reactions in the physiological activities of organisms' cells. Compared with pasteurization, microwave sterilization has the following significant characteristics:

A、 Microwave sterilization is a physical sterilization method that can kill harmful microorganisms such as bacteria, mold, insect eggs, and viruses without the need for chemical preservatives. During the process of killing harmful microorganisms, it will not contaminate food residues with toxic or radioactive substances, and is safe and harmless. It will not change the color, aroma, or nutritional content of the food.

B、 At the same sterilization temperature, the required sterilization time is short and preheating is not necessary. The killing time for Escherichia coli is about 30 seconds. Under the same sterilization conditions, the lethal temperature of bacteria is relatively low, and the sterilization effect is extremely significant.

C、 It can simultaneously carry out overall sterilization on the list of sterilized materials, greatly shortening the sterilization cycle and ensuring sterilization consistency.

D、 Due to the simultaneous sterilization of various parts of the material, the sterilization time is short, which can avoid the impact of prolonged heating on food quality, especially for foods that are not suitable for sterilization at higher temperatures or longer heating times. For example, ginger powder with volatile spice components, fresh and tender jellyfish with high moisture content, etc. For materials that require both color, aroma, and taste preservation and sterilization, microwave sterilization can achieve the best results.

E、 Microwave sterilization can be divided into post packaging sterilization and pre packaging sterilization. Packaging containers should not be made of metal and should be made of dielectric materials. Generally, plastic flexible packaging or glass is used, and engineering plastic containers are preferred. To prevent bag swelling during microwave sterilization, the equipment can apply pressure in the working chamber and use reverse pressure sterilization technology to prevent bag swelling and loss.
