1,The principle of microwave drying:
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 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.
7, Suppressors.
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.
4, The spices/seasonings the microwave dryer suitable for drying:
Black / white pepper, clove, curry, ginger, cumin, red chilli powder, cinnamon, star anise, five flavored powder, garlic powder/slices, wheat gluten, onion, scallion, leek, paprika etc.
5, The advantage of the mcirowave drying equipment than other normal heat transfer drying:
1) Clean drying: microwave dryer no need coal/gas/wood as the source of heat, just need electricity.
2) Fast drying: normally 5-10 mins is enough for drying.
3) Drying totally: the price will drying from inside to outside.
No matter the spice is good or not on the heat transfer.
4) Kepp the material in original shape, no broken: the microwave dryer is loading the material on the
conveyor belt, will not break the material, keep the original shape and whole pc.
5) Deeply drying: mcirowave dryer can drying the spices to less than 3% moisture.
6) The microwave dryer is a multifunction equipment, during drying, it can sterilizing/heating/roasting for
the material, so that reached fragment enhance effect.
6, Our company's advantage on the mcirowave equipment.
1) 20 years' experience on produce the microwave equipment.
2) We supply not only the equipment but also the operation skills/production skills for your products.
3) Skillful installation and maintain team, with pass port, and know English well, after got invitation fly to your in 3 days.
4) Short delivery time: for different modle need different produce time, if you are in horry, we can
produce it firstly for you. Normally 15-20 make delivery.
5) We can help you to find/purchase/transit the relative equipment for the mcirowave dryer, such as
washing machine, cutting machines, packing machine etc.
6) Price:
We would like to compare
