Multi-layer flat rotating circulating type grain drying machine

Abstract

The invention discloses a multi-layer flat rotating circulating type grain drying machine. A body is rectangular, and an air inlet channel and an air outlet channel are arranged inside. A grain inlet and a grain outlet are formed in the outer portion. Multiple layers of parallel conveying belts are arranged inside from top to bottom. Each layer of conveying belt is of a closed-loop structure, and every two up-and-down adjacent conveying belts are opposite in rotation direction. Grain enters the conveying belts from the grain inlet and falls onto the next layers of conveying belts after rotating along with the conveying belts by a circle, the process is repeated in a similar way, and the grain is dried on each layer of conveying belt in sequence and is finally output from the grain outlet in the bottom. Air enters a box body through the air inlet channel and is blown out from an air outlet. The multi-layer flat rotating circulating type grain drying machine is high in adaptability, good in use effect, low in machining cost and small in occupied area; and the technical problems that in the prior art, drying efficiency is low, machining cost is high, grain is damaged seriously, cost and power are wasted during mounting, and movement cannot be achieved are solved.

Description

technical field [0001] The invention relates to a grain dryer, in particular to a multi-layer horizontal rotation circulation type grain dryer. Background technique [0002] Food is the most important thing for the people, and grain drying is a necessary part of food safety. By drying, the moisture content of the grain can be reduced below the safe moisture level to prevent the grain from going moldy. [0003] At present, grain drying is divided into four methods according to the direction of hot air blowing in the world: 1. Downstream method, 2. Countercurrent method, 3. Mixed flow method, 4. Cross flow method. These four methods can only stand up the drying tower, load the grain from the upper part of the drying tower, gradually sink the grain by gravity, and discharge it from the bottom. Although the above drying methods have been improved and perfected for more than 30 years, the purpose of drying grain has been realized, but there are many disadvantages. The main dis...

AI Technical Summary

Problems solved by technology

Inside the air inlet channel and the air outlet channel, there are multiple layers of conveyor belts parallel to each other from top to bottom. Each layer of conveyor belts has a closed-loop structure and the upper and lower adjacent conveyor belts present opposite rotation directions. Grain enters from the grain inlet to the conveyor belt. After the conveyor belt rotates a circle, it will be blocked by the grain distribution plate and transferred to the next layer of conveyor belt, and so on, drying on each layer of conveyor belt in turn, and finally from the bottom of the grain outlet Output; the above-mentioned structure on the box body also solves the technical problems existing in the prior art, such as low drying efficiency, high processing cost, serious grain damage and laborious installation costs that cannot be moved
