1,The principle of microwave drying--the material itself heated, no need heat transfer:
Microwave is a kind of electromagnetic wave with the frequency 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 medium and then to rise the temperature of materials. So that accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating/drying is achieved.
2, the structure of the microwave drying equipment:
1, SS mcirowave heating cabinet with check window.
2, TEFL conveyor belt, and driving motors.
3, Microwave source parts: Magnetron, capacitor, cillicon, transformer, cooling fans.
4, Ehaust fan.
5, Support frame.
6, Loading and unloading parts.
3, Main parts of the mcirowave source(producer):
The producer of hte mcirowave--magnetron.
Cooling fan for the magnetron and the transformer.
The transformer, capacitance, cilicon.
3 The advantage of the microwave equipment for drying:
1) Fast drying: According the the moisture container level, 5-30 mins is enougth.
2) Clean drying: This is electricity dryer, no need coal/gas/wood etc as the heating source,
so that no air pollution.
3) Drying from inside to outside of the wood. So that will no outside dried and inside still not.
And prvent the situation of
4) Kill the worm eggs in the bamboo.
5) Heating in the same time for the shape fixation.
4, welcome to visit our factory, and take the sample to have a test.
5, The customers who use the microwave equipment to dry/heat/sterilize the bamboo products:

The working attitude of the company and the continuous improvement of the innovation concept will lead Tuo Bo and you to step into the brilliant future hand in hand and create a better future.
Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, No microwave heat transfer microwave dryer power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.
microwave dryer is a new type of environmental protection drying method. When dry, No microwave heat transfer microwave dryer directly to the medium molecules converted into heat, because the No microwave heat transfer microwave dryer penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.
microwave dryer advantages of equipment
1, microwave dryer, short, fast
Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The No microwave heat transfer microwave dryer is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.
2, No microwave heat transfer microwave dryer low temperature sterilization keep the nutrition and traditional flavor The No microwave heat transfer microwave dryer is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
3 microwave dryer and No microwave heat transfer microwave dryer save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
