cashews, filbert and dried fruit etc; and for leisure food, pachyrhizus chips, potato chips, dried
shrimps, fish maw and so on. Compared with the traditional production methods, microwave baked
foods are crispy and delicious, products particle puffed full, natural color, beautiful appearance, and
has insecticidal sterilization effect.
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 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 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 result 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 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 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 rupure.
6. Function: drying herbs, also can sterilze herbs at the same time
Main application features
Comparing to ordinary equipment, efficiency can be increased 80%,speed is eight times.
This machine is used to dry and sterilize the green leaves, herbs, herbs leaves, medicinal crops medicinal herb, moringa leaves, stevia leaves, and other herbs and leaves.
Because these leaves have many nutrition that are good for our body.So in the drying process,we must keep the original nutrition,and color.
Also after the microwave drying sterilization processing, the bacterium in the leaves have been killed.It can longthen the quality guarantee period

Microwave drying features
1, Fast heating. Microwave heating is completely different with traditional heating mode. It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.
2,Save energy and efficiency. Because materials contain water absorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, so high thermal efficiency, save energy.
3, Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat. So heating good uniformity, won't appear the endogenous phenomenon focal.
4, Mouldproof, sterilization, fresh. Microwave heating has thermal and biological effect, can sterilize and mould proof in low temperature.Due to heating rapidly, the time is short, can maximum limit save material activity 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 immediately, 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.
Introduction of microwave machine
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.
The Microwave Sterilization is the use of the electromagnetic field effects and biological effects play a role in the killing of microorganisms. Practice has proved that using microwave device to maintain the sterilization temperature, sterilization time, product quality, product shelf-life and energy-saving aspects have a clear advantage.
