DEVICE FOR DRYING AGRICULTURAL FEED Russian patent published in 2014 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: device for drying the agricultural feed comprises a ventilator frame connected to the ventilator having a delivery pipe branch provided with a nozzle with curved grooves, the feed polymer coating having a gap in which the suction pipe of the ventilator is placed. The nozzle body is made of bimetal, and the curved grooves have a profile in the form of a "dovetail" and turn into a circumferential groove located on the inner surface of the nozzle behind the inlet opening. The ventilator is provided with a drive with the speed regulator and the temperature regulator. The temperature sensor is located in the ventilation duct. The delivery pipe branch of the ventilator is equipped with thermoelectric generator, which comprises housing with a passage channel and a set of differential thermocouples. In the passage channel of the housing the "hot" ends of the set of differential thermocouples are mounted, and the "cold" ends are located on the outer surface of the housing. The inlet of the passage channel through the nozzle is connected to the delivery pipe branch of the ventilator and its output is connected to the ventilation duct.

EFFECT: possibility of obtaining additional electrical energy to power the electronic control system of the ventilator in the field.
