Industrial batch microwave oven is different from traditional drying method, and its heat conduction direction is the same as water diffusion direction. Compared with traditional drying methods, it has many advantages, such as high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality, so it has been paid more and more attention in various fields of drying.
Batch microwave oven is widely used in production and life. The purpose of drying is to remove water or solvents from some raw materials, semi-finished products and finished products so as to facilitate processing, use, transportation and storage.When the material is heated by microwave, the polar molecule of the heated material oscillates and rubs back and forth with the microwave frequency at billions of times per second. The heat generated is enough to make the material hot-dry in a very short time. Under this action, the material is heated both inside and outside.
Performance characteristics of industrial microwave ovens:
Industrial microwave oven heating is fast and uniform: it does not need heat conduction process, it can penetrate the heated material in an instant, penetration depth can reach several centimeters, or even more than a dozen centimeters, seconds to tens of seconds can turn microwave energy into heat energy. Microwave has selective heating to make heating more uniform. Industrial microwave oven is energy-saving and efficient: because the substance containing water is easy to absorb microwave and heat, there is almost no other loss except a small amount of transmission loss. Compared with far infrared heating, microwave heating saves 1/3 of energy.
Industrial microwave oven anti-mildew, sterilization and fresh-keeping: microwave heating has thermal and biological effects, so it can sterilize and sterilize at lower temperature; it can better preserve the activity of materials and vitamins, color and nutritional components in food. Industrial microwave ovens are advanced in technology and can be continuously produced. As long as microwave power is controlled, heating or termination can be realized. It has a perfect transmission system, which can ensure continuous production, realize computer control and save labor.
