Described feed pipe is obliquely installed.
Described blower fan is centrifugal fan.
The quantity of described rotation roller is 3.
The beneficial effects of the utility model are:
1, after this utility model adds crops, with opening lid sealed feed inlet, opening blower fan, under the drive of blower fan, the steam discharged from discharging opening can reenter casing internal along return duct, makes the energy in steam reuse, and the utilization rate of the energy is higher；
2, the first vibrosieve, the second vibrosieve, the screen surface of the 3rd vibrosieve have all been additionally arranged electrothermal tube, electrothermal tube is utilized directly to contact with crops, accelerate crops rate of drying, the inner upper end of casing fixes infrared heater, crops are dried by the infra-red radiation effect utilizing infrared heater, compared with traditional structure, crops rate of drying is faster；
3, being connected by spiral helicine feed pipe between the top of charging aperture, casing, spiral helicine feed pipe is compared with straight type pipe, and crops charging stroke is long, and the collision in crops fill process and between feed pipe is more violent, is conducive to fully breaing up caking crops；
4, rotate roller quick rotation under the drive of the second motor, play secondary and break up the effect of caking crops, it is simple to crops are dried；
5, this utility model utilizes auger carry material, simple in construction, practical.
6, feed pipe is obliquely installed, and fully breaks up caking crops.
