Microwave technology for heating cooked food, food by microwave radiation can be heated. The principle, high frequency oscillation of microwave energy is generated heat, which can penetrate the food inside the food in a short time the temperature increased, while the food can also kill harmful bacteria, keep the nutrition in food components and maintain the traditional flavor, extend the period of food preservation, improve product quality has a significant effect. Therefore, the application of microwave energy technology is more show its importance. Special features of microwave energy for heating food in a very short time, and can get the temperature of sterilization will kill E. coli in food. When the heating temperature of food by 80 - 90 ℃, a temperature of just 2 - 3 minutes, greatly reduced the total number of bacterial strains, over traditional heating methods. So that the number of fast-food enterprises in the production process or the continuous use of the tunnel microwave equipment converter quick lunch back to temperature, sterilization, has played an unprecedented effect. 
 The device for heating the cold chain fast food box, low temperature sterilization by microwave heating over the box fast food, low temperature sterilization to keep the original item to nutrients. Treated by the cold chain equipment, fast food box without any pollution, clean sanitation, disinfection and sterilization fast, uniform heating and good features, this machine also apply to drinks, tableware sterilization. 
 Most major cities in Shanghai and other catering businesses use of such equipment. Because the company's lunch, the output is relatively large, are into cold storage for preservation, to the room when they need a Microwave thawing.
