Microwave is electromagnetic waves which frequency from 300 MHZ to 300000 MHZ.Water molecule of heating medium material is polar molecule, its polarity orientation of the electric field with changes caused by the movement of molecules under high rapid frequency electromagnetic field changes, cause the numerator movement and the friction effect of each othe. Microwave field can field at this time into medium heat, make temperature of material increase, produce and popped a series of materialization process to reach the purpose of microwave heating dry.
Application of Microwave food products drying equipment
Microwave food products drying equipment for vegetable, microwave dehydrator machine, microwave drying and sterilization equipment is very widely used in drying and sterilizing powder, granular, flakes or colloidal form foods, nutritional heaLDh products, grain, agricuLDural and sideline products(rice, cornmeal), bamboo shoot, tea(wild chrysanthemum flower, broadleaf holly leaf, lotus leaf, green tea, black tea, puer tea),ginseng, mushroom, agaric, ganoderma, vegetables and fruits(spinach, carrot, parsley, onion, mango slice, apple slice,lemon slice, kiwi slice, banana slice etc.), preserved fruits, red jujube, non-fried(oil saving) instant noodles, noodles, cookie, biscuit, rice powder noodles, chicken jerky, beef jerky, preserved meat, dried fish, seafood(seaweed, sea cucumber, laver, kelp, sardine, shrimp, abalone etc.), pickles, spices(pepper powder, Chicken essence, beef essence, pork essence, yeast extract, seafood extract, seafood soup essence, seafood soup powder, spareribs soup pure, spareribs soup powder, spice, chili powder, ginger powder, garlic powder, aniseed, cinnamon, angelica, cumin, cassia bark, fennel etc.), egg yolk powder, jam, a variety of small packaging and pet food mildew sterilization preservation.

The principle of microwave heating
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 aLDer with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.
The principle of microwave sterilizing
Mircowave sterilizing is the resuLD of combined action of the thermal effect of eletromgnetic fields and the biological effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .The biological effects of microwave on the bacteria is that the microwave electric field changes the potential distribution of cross-section of the bacterial cell membrane and impacts the concentration of electron and lon around the membrane ,and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a resuLD they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compacLDy hydrongen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupture.
