NEW technology curry leaves drying equipment
1, The working principle of microwave drying equipment:
Microwave is a kind of high frequency wave, transform at a speed of 2.4 billion times per second, cause high speed wheel pendulum motion of water molecules, they mutual friction produces a great quantity of heat, easy to dry materials.
After object absorbing microwave energy and converted into heat, temperature of object rise up, containing moisture evaporation, dehydration, drying; If properly control the dehydration rate, when to dry material can make the material inside structure hydrophobic, puffing. In the process, also can control the higher heating temperature, make the object in a state of baking.
2, Application of the mcirowave drying equipment:
Microwave drying technology has been used in food industry in China, material chemical industry, pharmaceutical industry, mineral industry, ceramic industry, laboratory analysis, wet natural rubber processing, etc.
The mcirowave dryer for vegetables drying, such as: Onion slice/powder, all kinds of leaves of vegetables, Ginger slice, Garlic slice, Red chilli/ Red chilli powder, Potato slice, Sweet potato slice, Carrot slice, spices leaves, Green onion, Shallot, Scallion, Spinach, Day lily, Lettuce slices, Green onion, Ginger slice, Cabbage, Eggplant, Lotus root slices, Bitter melon, Pumpkin Grain, Long beans etc.
3, The advantage of the mcirowave drying equipment:
Compare with the traditional drying methods (air, steam, electric heating, etc.), microwave drying has the following significant "high quality, high efficiency, energy 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 energy consumption usually reduce more than 50%;
(4) realized safe and clean production.

4, The main parts of the microwave equipment:
Microwave heating sterilization device includes the following parts:
1. Produce microwave parts, mainly by the microwave generator, microwave tube;
2. The furnace and furnace cavity, with reflective microwave materials, can produce a microwave
resonance;
3. The furnace and microwave agitation or dispersion device;
4. The sealing door parts, to prevent microwave leak;
5. Operation control part includes safety interlocks.
Now mass produced microwave equipment mainly is tunnel type with the conveyor belt.
