Large scale microwave drying equipment

1、 Microwave sterilization features: 1. Short time and fast speed: Conventional thermal sterilization transfers heat from the surface of food to the interior through conduction, convection, or radiation. It often takes a long time to reach the sterilization temperature. Microwave sterilization is the direct interaction between microwave energy and microorganisms such as food and bacteria, with both thermal and non thermal effects working together to achieve rapid heating and sterilization, greatly reducing processing time. The sterilization effect of various materials is generally within 3-5 minutes. Low temperature sterilization maintains nutritional content and traditional flavor. Microwave sterilization is achieved through special thermal and non thermal effects. Compared with conventional thermal sterilization, it can achieve the desired disinfection and sterilization effect at lower temperatures and in a shorter time. Practice has proven that sterilization can be achieved at temperatures between 75-80 degrees Celsius. In addition, microwave processing of food can retain more nutrients and flavors such as color, aroma, taste, and shape, and has a puffing effect. The vitamin C retained by vegetables treated with conventional heat is 46-50%, while microwave treatment is 60-90%. Vitamin A in pig liver treated with conventional heat is maintained at 58%, while microwave heating is 84%. 2. Energy saving: Conventional thermal sterilization often results in heat loss in the environment and equipment, while microwaves directly treat food without additional heat loss. By comparison, it can generally save about 30% electricity. 3. Uniform and thorough: Conventional thermal sterilization starts from the surface of the material and then transfers to the interior through heat conduction. There is a temperature difference between the inside and outside. In order to maintain the flavor of food and shorten processing time, the internal temperature of the food is often not sufficient, which affects the sterilization effect.. Due to the penetrating effect of microwaves, they have a holistic effect on food .....
