Raw state grain drying apparatus

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%. ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an original ecological dehydration and drying device for grain, which can effectively overcome the problems of small precipitation, high energy consumption, high operating cost, poor quality of baked grain, baked grains, sticky grains and grains existing in the prior art. Problems such as excessive raw grains, paste grains and fire, etc., have reasonable dehydration process, easy operation, high control precision, low investment, energy saving, low operating cost, large precipitation at one time, uniform dehydration, and maintain the original ecological quality of baked grains. Bright color as natural drying, high yield and other advantages
