Conveyor Belt Grain Dryer

Abstract

A belt-based grain dryer is used to solve the problems of large volume, inconvenient movement and high investment cost of grain crop drying equipment. The structure of the present invention consists of two stages of dry layers with the same structure. The grain is transported through the conveyor belt in the drying layer, and the moving speed of the conveyor belt is adjusted according to the humidity of the grain, which can be used to solve the problem that the drying time of the current drying equipment cannot be adjusted. In the drying process, the invention utilizes the grain scraper to evenly spread the grains with equal thickness. When working, the hot air blown from the hot blast stove enters from the lower side of the equipment, and the upper side uses a suction fan to suck out the moisture. The smoke from the hot blast stove also enters the drying layer, which greatly reduces energy consumption. The invention has good drying effect, simple structure, convenient movement, high efficiency and low investment.

Description

technical field [0001] The invention relates to an automatic device for rapidly drying grain, belonging to the technical field of grain drying. Background technique [0002] my country's grain drying also mainly relies on the sun to dry, and the grain is placed on the ground and dried in the sun. In case of cloudy and rainy weather, the loss of grain mildew will be great, which will cause huge losses to the country's grain production and processing. become unrealistic. The drying of mechanical dryers is not restricted by weather conditions, but the equipment currently used for drying grains is bulky, difficult to assemble and move, and the cost of equipment is high; grains need to be dried by falling by their own weight, although hot air is used The principle of bottom-up countercurrent heat exchange is adopted, but the energy is not well utilized; the drying time of the grain is uncontrollable, resulting in a great waste of resources and even damage to the nutritional con...
