Multilayer grain drying device

Abstract

The invention discloses a multilayer grain drying device. The grain drying device comprises a shell, an impurity removal structure and a drying structure; the impurity removal structure and the dryingstructure are located in the shell; the impurity removal structure comprises a conveyor belt, a color sorter and a plurality of electric push rods; the color sorter is connected with the electric push rods electrically; and the electric push rods are located above the conveyor belt. According to the grain drying device, uniform drying of grains can be ensured furthest, and the drying degree is easy to control; and the breakage rate of the grains can be reduced greatly.

Description

technical field [0001] The invention belongs to the field of grain processing equipment, in particular to a multi-layer grain drying device. Background technique [0002] my country is a big grain country, and grain production and storage are related to people's livelihood. Grain drying is a necessary part of food safety. Through drying, the moisture content of the grain can be reduced to below the safe moisture level to prevent the grain from going moldy. The demand for grain drying equipment in our country is very huge. [0003] Especially for the preservation of a large number of grain seeds, higher requirements are put forward for the drying device. The slow dehydration process must be completed within the specified temperature range in order to maintain the activity of grain seeds to the greatest extent. Although the traditional drying process can There is a high probability of maintaining the activity of grain seeds, but the weather factors have too much influence on ...

Problems solved by technology

[0003] Especially for the preservation of a large number of grain seeds, higher requirements are put forward for the drying device. The slow dehydration process must be completed within the specified temperature range in order to maintain the activity of grain seeds to the greatest extent. Although the traditional drying process can There is a high probability of maintaining the activity of grain seeds, but the weather factors have too much influence on the construction. When the weather is bad, the drying cannot be completed in time

Today's dryers generally use coal to generate a large amount of heat to dry grain seeds, but the temperature control of this drying method is not very precise, and it is easy to cause the grain seeds to lose water quickly in a short period of time, resulting in the loss of activity of the grain seeds; On the other hand, in order to keep the drying evenly, it is necessary to use the auger to continuously stir the grain seeds. During the mechanical stirring process, the damage rate of the grain seeds will inevitably increase. Therefore, there is an urgent need for a drying machine that can simulate the traditional drying process to the greatest extent. dry grain drying equipment
