A grain dryer with automatic moisture monitoring

Abstract

The invention belongs to the technical field of grain dryers, and discloses a grain dryer with an automatic moisture monitoring function. The grain dryer includes a dryer body, an air inlet, a draughtfan, a burner and a grain feeding elevator, and the dryer body comprises a feeding port, a first drying box, a second drying box, a third drying box, a fourth drying box, a buffer box and a dischargeport; and the exhaust end of the grain feeding elevator is arranged above the feeding port, the lower end of the first drying box is provided with a first exhaust valve, the lower end of the second drying box is provided with a second exhaust valve, the lower end of the third drying box is provided with a third exhaust valve, and the lower end of the fourth drying box is provided with a fourth exhaust valve. The grain dryer with the automatic moisture monitoring function has simple structure, high energy utilization efficiency, automatic moisture monitoring function, sufficient grain drying,and wide application prospects.

Description

Technical field [0001] The invention relates to the technical field of grain dryers, in particular to a grain dryer with automatic moisture monitoring. Background technique [0002] All kinds of grains harvested in agriculture are subjected to dehumidification and drying treatment, and the purpose of dehumidification and drying treatment is to reduce the internal water content and the water content in the grain. On the one hand, reducing the water content can reduce the self-respiration of the grain and consume energy; On the other hand, avoid too high moisture content to cause grain germination and mildew. The large-scale grain drying in the prior art mainly uses grain dryers, which have the advantages of short dehydration time and high drying efficiency, which effectively guarantees the quality of grain storage, reduces the chance of grain mildew and germination, and is important for ensuring food safety Played a vital role. In recent years, grain dryers have developed rapidly...

Problems solved by technology

[0003] However, there is still room for improvement in the grain dryers in the prior art; for example, the existing grain dryers have the disadvantage of being unable to monitor the moisture in the grains in real time. The grains are discharged from the discharge port, which cannot ensure that the grains are fully dried. On the other hand, in the prior art, the dryer usually only has a drying box. In the actual drying process, the hot air blows through the grains and is directly discharged, and the temperature of the discharged air is still low. Relatively high, a lot of energy is wasted virtually, which increases the drying cost
