Problems solved by technology

That is, the high-temperature and high-pressure refrigerant flows into the evaporator to achieve the defrosting effect, but due to the conversion of the heat exchange effect between the condenser and the evaporator, the condenser that originally supplied the dry hot air in the barn is converted to provide cold air. The cold wind pours into the barn, destroying the original dry environment in the barn

Abstract

The invention relates to the field of cereal drying, and in particular relates to a cereal drying machine. The cereal drying machine comprises a drying tower (1) and a heat pump (2) which is communicated with the drying tower (1) and is used for providing hot air for the drying tower, wherein the heat pump (2) comprises a pump shell (3) and an evaporator (4) arranged in the pump shell; the cereal drying machine is characterized by further comprising a dust collection room (5) which is communicated with the drying tower (1) and is used for collecting waste air discharged by the drying tower; and a defrosting heating device is arranged on the evaporator (4). The cereal drying machine can efficiently filter the discharged waste air, and the phenomenon that cold air is generated at an air outlet where the evaporator is positioned during defrosting of the evaporator is avoided.

Description

technical field [0001] The invention relates to the field of grain drying, in particular to a grain drying machine. Background technique [0002] The process of grain from harvesting to storage requires drying of the grain to facilitate subsequent processing or long-term storage of the grain. The heat pump grain dryer has the advantages of less pollution, low energy consumption and low cost compared with the traditional dryer by burning fuel. Therefore, there are more and more heat pump grain dryers in the prior art. Dryers used to replace traditional fuel-burning methods. [0003] The grain dryer in the prior art mainly includes a heat pump and a drying tower, and it mainly has the following disadvantages: [0004] 1. The hot air supplied by the heat pump passes through the drying layer to dry the grain, and the exhaust gas discharged carries a large amount of dust particles such as chaff. Direct discharge will cause air pollution, which will not only affect the personal ...
