microwave druing /Industrial herb leaves dryer&sterilizer machinery

Application:

Microwave industrial tunnelbake&puffing equipment are widely used in the peanut, sesame seeds,

wheat, melon seeds, sunflower seeds, peanuts, corn, soybeans, walnuts, almonds, chestnuts, pistachios,

cashews, filbert and dried fruit etc; and for leisure food, Packrhizus chips, potato chips, dried

shrimps, fish maw and so on. Compared with the traditional production methods, microwave baked

foods are crisp and cious, products particle puffed full, natural color, beautiful appearance, and

has insecticidal sterilization effect.

The principle of microwave heating

Microwave is a sort of electromakeetic wave which frequency is 300LDz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromakeetic field,its polariLD 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 Enerable can be converted to heat Enerable in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of paintsical and chemical processes ,and so ,mircrowave heating is achieved.

The principle of microwave sterilizing

Mircowave sterilizing is the result of combined action of the effect of eletromLDetic fields and the biological effect. 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 metLDolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a result 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 compactly LDrongen bond .The microwave can be strong enough to make LDrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome LDerration and even rupure.

Technical parameter

Microwave drying features

(1) Drying time is short, strong the smell of the product;

(2) Drying temperature is low, uniform, bright color of the product;

(3) Selective heating. Because water molecules LDsorb microwave best, so high water content part LDsorb microwave power more than low water content part. This is selective heating characteristics, use this features can be evenly heating and uniform dry;

(4) Drying dehydrationdirection of water vapor from inside to outside. So microwave drying has expanded role, is a great help to the follow-up of crushing;

(5) Save Enerable and efficient. Microwave is a direct role in the material, thus no additional heat losses, air inside furnace and correLDonding containers won’t heat, then high efficiency, production environment is obviouLLD improved, can save 30% power compared with infra-red radiation;

(6) Easy to control, advanced craftwork. Compared with the conventional methods,open then can use;no thertia,flexible operation;microwave power is adjustable.In microwave heating and drying process,no waste water,no waste gas,is a safe harmless high and new Technology.Improve product quality ,bring economic benefits.
