Device for reducing water of high moisture granular mixture material in cabin in balanced mode

Abstract

The invention discloses a device for reducing water of a high moisture granular mixture material in a cabin in a balanced mode. The device comprises an exploring tube and a core column, wherein two ends of the exploring tube penetrate, and a plurality of pores are formed in the side wall of the exploring tube; and one end of the core column stretches into the exploring tube and can slide up and down in the exploring tube. According to the device disclosed by the invention, the exploring tube is inserted into the cabin to guide air, and the core column moves up and down in the exploring tube tocontrol the height of an air guiding section of the exploring tube to guide a dry medium (air) into a high moisture material gathering region in the cabin in a fixed direction and in a positioned mode for reducing water and drying the material, so that moisture and moisture gradient in a material pile meet the demand. Therefore, the ventilating and drying uniformity and the drying efficiency of cereals in the cabin are improved, and the problem that in the prior art, the cereals are not uniformly dried in a drying mode of straight air can be solved.

Description

technical field [0001] The invention relates to the technical field of barn precipitation and dehumidification equipment, in particular to a device for balanced precipitation of high-water dispersed granular materials in a barn. Background technique [0002] Drying in the warehouse is to dry the high-water dispersion granular materials (such as rice, wheat, corn, soybeans, miscellaneous grains, seeds, etc.) in the warehouse at low temperature by means of mechanical ventilation and heating. Technology. Upward ventilation is often used in the drying process of materials in the warehouse. The so-called upward ventilation means that the outside air passes through the air distribution chamber at the bottom of the warehouse and the orifice plate at the bottom of the warehouse, and is discharged out of the warehouse through the material layer from bottom to top, so as to decompose the material. The water is evaporated and taken away to achieve the purpose of low-temperature drying...

AI Technical Summary

Problems solved by technology

However, practice has proved that during the upward ventilation and drying process of materials, the precipitation rate in the lower layer is fast, and the precipitation rate in the upper layer is slow, resulting in serious moisture stratification of the upper and lower layers.

At the same time, affected by physical factors such as the accumulation of impurities in the material and the anisotropy of the stockpile, the drying medium (air) flows unevenly in the stockpile, resulting in uneven precipitation of the material. Some areas have high moisture and some areas have low moisture.

However, moisture stratification and uneven precipitation make it easy to generate condensation, microbial growth and material mildew in the warehouse.
