Hot air circulation grain drying device

Abstract

The invention discloses a hot gas circulation grain drying equipment, which comprises a dehumidifier and a drying box; a dust removal channel is arranged above the drying box, and a winnowing device is arranged on the right side of the dust removal channel; the dust removal channel is connected with a cyclone dust collector A drying box is connected under the dust removal channel; a drying plate is arranged in the drying box; a first hot air blower, a second hot air blower and a third hot air blower are arranged between the drying plates. The present invention realizes the full utilization of the hot air and separate drying of the grains with different drying degrees by providing a circulating hot air drying device and hot air blowers with different powers, reducing heat loss and saving energy; the present invention is provided with staggered distribution The drying plate improves the drying efficiency and the drying effect; the invention is equipped with a high-school dust removal device to remove dust and shriveled grains in the grain, improves the quality of the grain, and saves storage space.

Description

technical field [0001] The invention relates to the field of grain drying, in particular to a hot gas circulation grain drying equipment. Background technique [0002] The grain needs to be dried before it is harvested and stored in the warehouse. The limitations of the traditional drying method are getting bigger and bigger. Firstly, a large area of ​​drying field meets the needs of drying, and secondly, it is impossible to dry the grain due to weather changes during the harvest season. The efficiency of drying is low, and it takes a lot of labor costs to spread the grain and collect it. With the improvement of grain varieties, the increase of per unit yield and the increase of the country's investment in grain drying equipment, more and more large, medium and small grain drying facilities are being built. [0003] The traditional drying device consumes a lot of energy. When using hot air to dry, the humid hot air generated is directly discharged into the air, which not on...

AI Technical Summary

Problems solved by technology

[0003] The traditional drying device has high energy consumption. When using hot air to dry, the humid hot air generated is directly discharged into the air, which not only pollutes the environment, but also causes a large amount of heat loss. The drying efficiency is not high, resulting in huge energy consumption and waste of resources. At the same time, the grain itself contains a lot of dust and flat grains, and there is a lack of devices to deal with dust and flat grains
