Multi-layer horizontal rotation circulation grain dryer

Abstract

The utility model relates to a multi-layer horizontal rotation circulation type grain dryer, the main body is in the shape of a rectangle, and an air inlet channel and an air outlet channel are arranged inside. The grain inlet and the grain outlet are arranged on the outside. Inside, there are multiple layers of conveyor belts parallel to each other from top to bottom. Each layer of conveyor belt is a closed-loop structure and the upper and lower adjacent conveyor belts present opposite rotation directions. Grain enters the conveyor belt from the grain inlet and rotates along with the conveyor belt. After the circle, it lands on the conveyor belt of the next layer, and so on, it is dried on each layer of conveyor belt in turn, and finally output from the grain outlet at the bottom; the air enters the inside of the box through the air inlet channel, and the blow out. The invention provides a multi-layer horizontal rotation circulation grain dryer with strong applicability, good use effect, low processing cost and small footprint, which solves the problems in the prior art, such as low drying efficiency and low processing efficiency. The technical problems of high cost, serious food damage and laborious installation cost cannot be moved.

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
