Grain drying equipment with high drying efficiency

Abstract

The invention provides grain drying equipment with high drying efficiency. The grain drying equipment comprises a support frame, a drying channel, an elevator and a drying furnace assembly, wherein the drying channel is installed in the inner side of the support frame; the elevator is installed at one side of the support frame, and the top end of the elevator is connected with an inlet of the drying channel; and the drying oven assembly is installed at the other side of the support frame. According to the grain drying equipment, the zigzag drying channel is adopted, so that the drying time of grains in the drying equipment is prolonged; a preheating section, a heating section and a discharging section are arranged in the drying channel, the grains are dried, the grains in the preheating section are evenly spread through a scraper which moves repeatedly in the preheating section, and the grains evenly flow into the heating section, so that the drying effect of the drying equipment is improved; and moreover, the temperature of hot air is increased through an auxiliary heating device arranged at the bent position of the drying channel, so that the drying efficiency of the drying equipment is greatly improved, and the circulating frequency of grain drying is reduced.

Description

technical field [0001] The invention belongs to the field of grain drying equipment, in particular to a grain drying equipment with high drying efficiency. Background technique [0002] Grain is an important special commodity, an important strategic material related to the national economy and people's livelihood, and the most basic means of subsistence for the survival and development of human society. It occupies an important position and role in the national economy. Grain drying is an important part of post-production of grain and an important means of guaranteeing the return of grain grains to the warehouse. However, after my country's grain is harvested, mildew, germination and deterioration in storage, transportation, processing and other links due to humid climate, too late to dry or fail to achieve safe storage of water, as well as the loss of throwing during the drying process, the total can reach my country's 5% of the total grain output is more than 70 billion ca...

AI Technical Summary

Problems solved by technology

[0003] The existing drying equipment lifts the grain to the top of the drying equipment through the elevator, and then scatter the grain down. Under the action of gravity, the drying equipment dries the grain during the falling process. The time is relatively short, and there is a problem that the drying efficiency of the drying equipment is low, and the hoist needs to repeatedly lift the grain for drying.
