All-weather fluidized bed method grain drier

Abstract

The invention provides an all-weather fluidized bed method grain drier. The all-weather fluidized bed method grain drier is characterized by comprising a bracket, a feed hopper, an outlet hopper, a transportation mechanism, at least one dehumidification segment, an air-drawing dust removing segment and a protective hood, wherein the feed hopper and the outlet hopper are arranged at the two ends of the bracket, the transportation mechanism is arranged between the feed hopper and the outlet hopper, the dehumidification segment and the air-drawing dust removing segment span over the transportation mechanism and are sequentially arranged, and the protective hood wraps outsides the dehumidification segment and the air-drawing dust removing segment. The all-weather fluidized bed method grain drier has the beneficial effects that standard unit module combination with one dehumidification segment as a unit is adopted, the amount of the dehumidification segment can be increased or reduced according to different actual processing capacities of users or different matters to be processed, and the length of the transportation mechanism as well as the sizes of the bracket and the protective hood are correspondingly increased or reduced, so that the drying needs of various users for different processing capacities and different matters to be processed are satisfied.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to an all-weather fluidized bed grain dryer. Background technique [0002] In my country, after the grain is harvested, its moisture content needs to be reduced to below 14.5% to meet the national storage standard, and the grain station can purchase it. Generally speaking, the vast rural areas are accustomed to using the method of drying in the open air to remove water, but this method is greatly affected by environmental conditions. If the grains are not dried after harvesting in cloudy and rainy days, it will cause great losses. , so the demand for artificial drying by mechanical methods is increasing. [0003] Existing mechanical grain drying methods usually use hot air to blow off the moisture on the surface and between the crumbs. Most of the heat sources use diesel combustion and bellflower combustion to heat the air. This method will pollute the grains and increase envi...

AI Technical Summary

Problems solved by technology

[0005] The moisture in the grain includes the surface water covered on the outer surface, the interlayer water contained between the grains and the crystallization water contained inside the grain. It is easy to be removed, while the crystallization water is located inside the grain and is closely combined with the internal substance of the grain through crystallization. It is usually difficult to be removed. Therefore, it is necessary to provide a large amount of heat and wind energy to remove the crystallization water in the mechanical grain drying method. The heat loss of the heat energy from the heating mechanism to the grain through the air duct is not large, but the wind energy often results in a large amount of wind energy loss due to the unreasonable structure of the air duct
