Hot air circulation drying equipment for grain

Abstract

The invention relates to a drying device, in particular to hot air circulation drying equipment for grain. The invention provides the hot air circulation drying equipment, which is simple in structure, rapid in temperature rise, small in temperature difference and easy in moisture removal, can be used for drying materials in a circulating way and generates circulating hot air, for grain. The equipment comprises a hot air box body, a material box body and a lifting device, and is characterized in that the hot air box body is formed by assembling movable plates, the material box body comprises agrain cabinet, a feeding device, a material conveying device, a discharge device, a polygonal box, a blanking adjustment device and a support, and the lifting device comprises a material adding box,a material collecting box, a material adding device, a circulating material lifting device, a material conveying main pipeline and a material push packing auger; the material box body is arranged in the hot air box body. The hot air circulation drying equipment for the grain is low in manufacturing cost, simple to operate, convenient to use and easy to popularize.

Description

technical field [0001] The invention relates to a drying device, in particular to a grain hot air circulation drying equipment. Background technique [0002] After the grain is harvested, the new grain contains a lot of water and cannot be put into the granary. It must be dried to reach a certain amount of water before entering the granary. At present, the grain drying equipment varies greatly, each is different, and the effect is not the same. The commonly used equipment for hot air drying of hot air stoves is generally that the hot air stove supplies hot air to the box of the drying material through the pipeline. The disadvantages are: The equipment is huge, the cost is high, the floor area is large, and the utilization rate of heat energy is low. The disadvantage of this technology is that the temperature difference is large, the heat flow rate is slow, the phenomenon that the material in the middle is cooked, the drying speed is slow, the drying cycle is long, the quali...

Problems solved by technology

At present, the grain drying equipment varies greatly, each is different, and the effect is not the same. The commonly used equipment for hot air drying of hot air stoves is generally that the hot air stove supplies hot air to the box of the drying material through the pipeline. The disadvantages are: The equipment is huge, the cost is high, the floor area is large, and the utilization rate of heat energy is low

The disadvantage of this technology is that the temperature difference is large, the heat flow rate is slow, the phenomenon that the material in the middle is cooked, the drying speed is slow, the drying cycle is long, the quality of the dried material is poor, and the energy consumption is high.
