Grain drying and air drying integrated drying process

Abstract

The invention provides a drying and air-drying integrated drying process of cereals. The drying and air-drying integrated drying process comprises the following steps that firstly, grains are uniformly conveyed in a drying mechanism at a uniform speed through a constant-speed feeding mechanism; secondly, the drying mechanism blows hot air from bottom to top to enable the grains to be suspended androlled and to move upwards slowly, and in the process, the grains are subjected to comprehensive drying treatment, and then hot air flow and the grains enter the air drying mechanism together; then,the air drying mechanism separates the grains from the hot air flow at the bottom of the air drying mechanism and converts the hot air flow into normal-temperature air flow; then, the grains and the normal-temperature air flow from bottom to top are converged in an air drying tank, and the normal-temperature air flow enables the grains to be suspended and rolled and move upwards slowly, and in theprocess, the grains are subjected to the comprehensive air drying treatment, and the normal-temperature air flow and the grains enter a cooling and discharging mechanism together; and finally, the cooling and discharging mechanism cools the grains with cold air and outputs the grains to a stacking point.

Description

technical field [0001] The invention relates to a grain dryer, in particular to an integrated drying process of grain drying and air drying. Background technique [0002] Grain needs to be dried before storage to reduce the moisture content of grain particles and avoid heating, mildew, and deterioration of grain during long-term accumulation and storage. The drying process of grain will directly determine the period and quality of grain storage. Therefore, no matter for For national grain depots, local grain stations and farmers, the drying of grain is very important. At this stage, national grain depots and local grain stations all use large-scale drying equipment to dry grain. The general structure of this drying equipment The principle is complicated, the production cost is high, the maintenance is difficult, and it is difficult to popularize it. Farmers still use natural drying to dry the grain, which is not only labor-intensive, time-consuming and labor-intensive, but a...

[0002] Grain needs to be dried before storage to reduce the moisture content of grain particles and avoid heating, mildew, and deterioration of grain during long-term accumulation and storage. The drying process of grain will directly determine the period and quality of grain storage. Therefore, no matter for For national grain depots, local grain stations and farmers, the drying of grain is very important. At this stage, national grain depots and local grain stations all use large-scale drying equipment to dry grain. The general structure of this drying equipment The principle is complicated, the production cost is high, the maintenance is difficult, and it is difficult to popularize it. Farmers still use natural drying to dry the grain, which is not only labor-intensive, time-consuming and labor-intensive, but also has low drying efficiency. In order to solve the problem of drying grain for farmers, the inventor designed an integrated drying method for grain drying and air drying that is ingenious in structure, simple in principle, low in cost, and easy to popularize and use.
