China new type effective customized microwave fish drying equipment for flounder fish
The advanage of the microwave dryer for the fish and fish products:
Compare with the traditional drying methods (air, steam, electric heating, etc.), microwave drying has the following significant "high quality, high efficiency, enerLD saving, environmental protection" features:
(1) to implement material non-polluting and uniform drying, at the same time, can greatly reduce the drying temperature;
(2) the drying speed is usually increased by more than several times, improve the production efficiency;
(3) drying enerLD consumption usually reduce more than 50%;
(4) realized safe and clean production.

Microwave drying principle:
Microwave drying is a new type of drying method. When drying, microwave converted into heat enerLD that can be applied directly to medium, because the microwave has penetrating performance inside and outside the media, heating at the same time, do not need to heat conduction, so very fast heating, the water content below 30% of food, can shorten the drying speed hundreds of times. Regardless of any shape objects, because the object of dielectric heating at the same time, both inside and outside material of inside and outside temperature difference is small, uniform heating, the drying quality greatly improved.
The main structure of the microwave equipment
1. Microwave production parts, the main parts of microwave equipment-- Magnetron.
2. The cabinet of the microwave equipment, material will be treated in it.
3. The microwave guide, microwave after produce by maganetron via wave guide’s
incent to worked on the material
4. The suppressor, because the industrial microwave equipment is a tunnel type
cabinet with the conveyor belt, so that it need suppressor in the head and end of the
tunnel to suppress the microwave running out.
5. The sealing door parts, for check the material in the cabinet;
6. The exhaust system, which use for exhaust the wet/hot air in the cabinet and
electric parts box.
7. Conveyor belt transit system, including belt/motor/speed reducer etc.
8. Operation control part includes safety interlocks, speed controller, switch on/off
bottom, temperature controller.
