Tunnel type microwave machine for drying and sterilizing wheat germ
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, drying, sterilize, roasting, puffing and a series of physical and chemical processes.
Features of Design
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 enerLD 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 enerLD.
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 thevitamin original colour and lustre and nutrition of food.
5.Craft is advanced, control easily
Microwave heating just have the basic conditions ofwater, 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 andharmful gases,do not produce the waste heat and dust pollution; Neither polluting food,also do not pollute the environment.

Tunnel type microwave machine for drying and sterilizing wheat germ
Advantages of Microwave Heating
(1) Tunnel belt microwave machine for drying and sterilizing wheat germ heating speed: Conventional heating (such as flame, hot air, electric, steam, etc.) are the use of heat conduction, convection, heat radiation to the heat first pass to the surface of the heated matter, and then through the heat conduction gradually increase the center temperature (both often called external heating). It requires a certain amount of heat conduction time for the central part to reach the desired temperature, and the time required for the object with poor heat conductivity is longer. Microwave heating is the internal heating mode, the electromagnetic enerLD directly affects the medium molecule to convert into the heat, and the transmission performance causes the material inside and outside medium to be heated simultaneously, does not need the heat conduction, but the interior lacks the heat dissipation condition, causes the internal temperature to be higher than the external temperature gradient distribution, forLD the driving internal moisture to the surface infiltration steam Accelerates the migration and evaporation rate of moisture. Especially for the water content under 30% food, speed can be shortened hundreds of times times, in a short period of time to achieve uniform drying.
(2) Microwave Crops LD sterilizer uniform heating: Heating with external heating, in order to increase the heating speed, it is necessary to raise the external temperature, increase the temperature gradient. However, it is easy to produce the endogenous phenomenon of external coke. Microwave heating, regardless of the shape of the microwave can be evenly penetrated to produce heat, so the uniformity LDly improved.
(3) EnerLD-saving, high efficiency: different materials on the microwave has different absorption rate, moisture content of the material easy to absorb microwave enerLD. Glass, ceramics, polypropLDe and so on are rarely absorbed microwave, metal will reflect the wave, these substances can not be microwave heating. Microwave heating, the heating materials are generally placed in a heated room made of metal, heating room for electromagnetic waves is a closed cavity, electromagnetic waves can not be leaked, can only be absorbed by heating objects, heating indoor air and the corresponding container will not be heated, so the thermal efficiency is high. At the same time, the environment temperature in the workplace will not rise, the production environment is obviously improved.
(4) Tunnel belt microwave machine for drying and sterilizing wheat germ easy to control: microwave power control is controlled by the switch, knob adjustment, that is, open both use, no thermal inertia, power continuous adjustable, easy to automate.
(5) Microwave Crops LD sterilizer cleaning: For food, medicine and other processing drying, microwave heating effect and biological effects can be at a low temperature quickly kill both, can limit the preservation of nutrients and the original color, so microwaves in the food industry has been widely used.
(6) Microwave Crops LD sterilizer selective heating: Different properties of the material to microwave absorption loss is different, the characteristics of selective heating, which is beneficial to the drying process. Because of the absorption loss of the water molecule to the microwave, so the area with high water content absorbs the microwave power more than the lower water content, thus the drying rate is consistent. However, some substances are negative temperature coefficient, the higher the temperature, εr and tgδ will increase, the better the absorption, resulting in positive feedback to make this part of the temperature rise sharply. The microwave heating of this kind of material must pay attention to the rational formulation of processing technoloLD.
(7) Tunnel belt microwave machine for drying and sterilizing wheat germ safe and harmless: microwave enerLD is usually transmitted in a closed heating chamber made of metal and in a channel tube. Using advanced design, so that the inlet and outlet, the Observation window microwave does not belong to radioactive rays, and no harmful gas emissions, is a very safe heating technoloLD.
