Description

Grain drying tower

Technical Field

The utility model relates to a grain processing technology field, in particular to grain drying tower.

Background

After being harvested, the grains need to be dried, so that the aims of reducing the moisture in the grains, killing worm eggs and improving the storage quality of the grains are fulfilled. At present, a drying tower for drying grains by hot air is mainly adopted, a large amount of hot air can be generated in a short time by adopting a rotary heating device, the hot air is fully contacted with the grains from top to bottom of the drying tower, the moisture of the grains is evaporated, and the uniformity of grain drying is ensured. Because above-mentioned grain is at the transfer and transportation in-process, can adsorb and be infected with the various dusts in the operational environment, lead to drying to produce a large amount of raise dusts and pollute the granary etc. when finishing the ejection of compact, in order to solve this problem, generally adopt external dust collecting equipment, utilize the hot-blast in filter sieve and the guide tower, with the dust granule suction in the grain, nevertheless grain falling speed is very fast, the dust removal is thorough inadequately, large-scale dust collecting equipment energy resource consumption is big simultaneously, lead to dust collecting equipment inefficiency.

SUMMERY OF THE UTILITY MODEL
