Air channel, the described end is communicated to microwave cavity inside from an end of microwave cavity, between air channel, the end and the microwave cavity volume adjusting apparatus is installed, and the dehumidifier assembling is at the opposite side of microwave cavity.
Carrying roller is installed below the described carrier bar.
The base plate of described microwave cavity is provided with the circular hole that diameter is 6mm.
The beneficial effects of the utility model are:
1, heated air circulation device; The air inlet of electric component cavity is installed air filter, makes the air of access arrangement electrical box without impurity such as bulky grain, dusts, avoids electrical equipment is damaged; Take away most of heat that electrical equipment produces during cold air process electric component cavity, thereby to the electric components effective cooling, reduced Special cooling device and power consumption expense thereof;
2, the hot-air that produces in the electric component cavity enters in the microwave casing by circulating fan and air channel, the end, utilizes the hot-air heat that material is carried out drying, can under the prerequisite that does not increase equipment microwave transmitting power, improve effect, the increase output of equipment;
3, owing to Air Quantity Required in the dry materials process of different humidity, different densities is different, between air channel, the end and the microwave casing volume adjusting apparatus is installed, can under the prerequisite that does not change the parts such as air channel, be regulated intake, improve drying effect.
