Embodiment Construction

[0023] according to Figure 1-7 The specific structure and working process of the present invention will be described in detail. The device adopts a combined structure, including an upper grain storage bin 19, a lower grain row bin 5, and various sections of the body 27 with polygonal boxes assembled therebetween and a control device composed of a conventional heating device, a detection device, and a control circuit. The conventional heating device includes general equipment such as hot blast pipelines, heat exchangers, and hot blast stoves. High, medium and low temperature hot air inlets 6, 7, 8 enter the body 27 to provide high temperature hot air, medium temperature hot air and low temperature hot air to complete the drying of grain. The detection device includes the high and low material level devices that are commonly used in the upper grain storage bin 19 for automatic control of feeding, which are commonly used in general grain dryers. Signals are sent through the pos...

Abstract

The raw state grain drying apparatus includes storing barn, discharging barn and machine and controller in between. The machine includes wind guiding no-bottom boxes in sandwich or single wall structure and slowly dewatering cavities crossly arranged inside the machine body, at least one heat-controlling slow dewatering part and one cooling and slow dewatering part, a hot blast port, a moisture discharging port and a cold blast distributor. The present invention is superior to available technology, and has high grain stoving quality, reasonable dewatering process, easy operation, high control precision, low power consumption, low running cost, great once dewatering rate and other advantages.

Description

technical field [0001] The invention relates to a thermal drying process of grain, in particular to a grain original ecological dehydration drying device using heat and humidity inertia as power, mainly suitable for dehydration and drying of corn, and also suitable for seed grain, rice, wheat, rapeseed Dehydration and drying of grains such as , sorghum and soybeans. Background technique [0002] With the rapid development of science and technology in our country, the output of grain in the agricultural system has doubled year by year, new varieties of grain have emerged continuously, and the water content of grain has also increased year by year. Therefore, in order to return the grain particles to the warehouse, it is necessary to increase the intensity of drying and precipitation for the freshly harvested grain, so as to achieve the purpose of safe storage. Taking corn in Northeast China as an example, the general moisture content is 25-28%, sometimes as high as 28-35%. ...
