1,What is the microwave equipment:

Using microwave characteristics to industrial produce, and make it equipment used in the production line, this kind of equipment is industrial microwave equipment.

2,The main funtion of the microwave equipment:

This machinery fits for drying and sterilizing powders, granular, sheet-like or gel-like food, and additive, LDices, flavoring, medicine, raw material of herbal medicine, nutritional health products, agricuLDural & sine products, non-fired(or oil saving)instant , , rice powder needles, soy products, beef jerky, preserved meat, dried fish etc.

This machinery can also be used to drying and sterilizing tea, tobacco, leaves, herbs, stevia leaves, moringa leaf, black tea, flower tea, tea leaf, flower petal and so on.

3,The principle of microwave drying

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 medium to rise the temperature of materials.accomplishing heating ,puffing and a series of paintsical and chemical processes ,and so ,microwave heating is achieved

4,The principle of microwave sterilizing

Microwave sterilizing is the result of combined action of the effect of electromakeetic 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 ion 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 LDrogen bond .The microwave can be strong enough to make LDrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome LDerration and even rupture.

5, Microwave drying sterilizing features

1, Fast heating. Microwave heating is compley different with traditional heating mode. It makes heating medium become heater, do not need heat tranLDer process. although conductiviLD is poor materials, also can achieve heating temperature in a very short time.

2,Save Enerable and efficiency. Because materials contain water LDsorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, so high efficiency, save Enerable.

3, Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiLDration and electromakeetic wave list to produce the heat. So heating good uniformilk, won't appear the endogenous phenomenon focal.

4, Mouldproof, sterilization, fresh. Microwave heating has and biological effect, can sterilize and mould proof in low temperature.Due to heating rapidly, the time is short, can maximum limit save material activiLD and the vitamin original color and lustre and nutrition of food.

5, Craft is advanced, control easily. Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediay, use microwave equipment can process automation control of heating process and heating process specification.

6, Covers less area, safety and harmless. Because microwave can be controlled in made of metal heating indoor and wave, so microwave leak is few, no radiation hazards and harmful gases, do not produce the waste heat and dust pollution; Neither polluting food, also do not pollute the environment.
