1,The principle of microwave drying

Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field enerLD can be converted to heat enerLD in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.

2, The principle of microwave sterilization

The Microwave Sterilization is the result of the role of the microwave thermal effects and biological effects. Affect the membrane around the electron and ion concentration microwave distribution of the cross-section of potential bacterial membrane permeability of the cell membrane, thus changing the enerLD, bacteria, therefore malnutrition

can not be normal metabolism, growth and development hampered by death. From a biochemical perspective, the normal growth and reproduction of bacteria nucleic acid (RNA) and deoxyribonucleic acid (DNA) is closely connected to the curl macromolecules by the number of hydrogen bonds, microwave cause hydrogen bonds the slack, breaking and reorganization, and induce genetic gene or chromosomal aberrations, or even broken. The Microwave Sterilization is the use of the electromagnetic field effects and biological effects play a role in the killing of microorganisLD. Practice has proved that using microwave device to maintain the sterilization temperature, sterilization time, product quality, product shelf-life and enerLD-saving aspects have a clear advantage.

3, Main used area

This machine fits for drying and sterilizing powders, granular, sheet-like or gel-like food, and additive, spices, flavoring, medicine, raw material of herbal medicine, nutritional health products, agricultural & sideline products, non-fired(or oil saving)instant noodles, noodles, rice powder needles, soy products, beef jerky, preserved meat, dried fish, tea, tobacco and so on; and for drying, peeling and baking almond, peach kernel, groundnut kernels, chestnut and so on; and for puffing of leisure food, pachyrhizus chips, potato chips, dried shrimps, fish maw and so on; and for thawing the frozen fish, poultry; and for drying beans; and for drying and desulfurating and deoxidizing the metallurgical chemical products; and for drying printing and dyeing products, ceramics, glass, chemical fiber, cotton yarn, wood, leather, bamboo products, insulation materials, building materials, wood , cork, alveolate, cardboard,corrugated cardboard, and so on.
