big capacity good effect microwave heating roasting equipment for peanuts and sunflower seeds
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 roasting.
Advantage and principle of the microwave equipment on roasting the nuts products:
Microwave roaster use the heating effect of the microwave equipment to work on the sunflower seeds, peanuts, sesame seeds, almonds, cashews, filbert etc nust.
This microwave roaster apply to the end of the nuts produce line, for last drying and roasting. The nuts processed via the microwave equipment, because more crispy, and fragrant enhenced, the moisture drop down to 3-5%. At the same time, the nuts have a puffing effect.
Why the nuts will have this effect after treated by the microwave equipment, just becaue the microwave heating meth. The microwave heating, is microwave penetrit from the meterial, the microwave take the water melcules running and friction, so that produce heat, that is to say, the material itself produce heat, and heat is from inside of the material. So that, drying fast, roasting with puffing effect.
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.
