Novel grain drying device

Abstract

The invention discloses a novel grain drying device. The device comprises a drying tower (1), a heat pump used for providing hot air for the drying tower (1) and a dust collection chamber (4) which is communicated with the drying tower (1) through a dust discharging pipe (2) and used for collecting grain dust. A blower (3) is arranged between the inlet end of the dust discharging pipe (2) and the drying tower (1), and a condenser (5) of the heat pump is arranged in a hot air inlet cavity (1-2) of the drying tower (1). Through the novel grain drying device, the drying efficiency of the drying tower (1) can be improved, the energy is saved, and the floor space of equipment can also be saved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a novel grain drying device. Background technique [0002] The process of grains from harvesting to storage requires drying of grains for subsequent processing or long-term storage of grains. The heat pump type grain dryer has the advantages of less pollution, low energy consumption and low cost than the traditional dryer by burning fuel. Therefore, there are more and more heat pump type grain dryers in the prior art. Dryers used to replace the traditional way of burning fuel. [0003] The grain dryer in the prior art mainly includes a heat pump and a drying tower. The heat pump compresses a gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant through a compressor, and then sends it to a condenser for heat dissipation to become a normal temperature and high-pressure liquid refrigerant. In this process, the heat emitted by the condenser is t...

Problems solved by technology

[0004] The heat pump generates hot air and enters the hot air inlet chamber of the drying tower. The hot air enters the grain placement layer through the air inlet holes on both sides of the hot air inlet chamber to dry the grain, and then the air flows through the exhaust duct outside the grain placement layer through The dust exhaust pipe is discharged into the dust collection chamber. In actual use, the temperature of the hot air will drop after entering the hot air inlet chamber, and the temperature of the hot air often cannot meet the needs of grain drying.
