Problems solved by technology

Although the powder and granular materials are divided into several groups, which can promote the uniform drying of the materials, the bonding between the material particles and the uniform drying of the interior and surface of the materials cannot be avoided.

Abstract

The invention discloses a drying tower with positive-negative shunt structures and a drying method thereof. The drying tower comprises a shell, a rotary shaft, a feed port, a discharge port, a shunt material channel and a rotational wind generation device, wherein the rotary shaft is arranged in the center of the shell and is provided with a shaft shell, a shaft cavity encircled by the shaft shell and a group of one-way holes arranged on the shaft shell; the shunt material channel is formed by a group of shunt structures which rotate around the rotary shaft serving as the shaft center, and the shunt structures are divided into the positive shunt structures and the negative shunt structures, which are alternately arranged; and the shunt structures are formed by a group of shunt gates comprising 4 to 32 shunt gates, and each shunt gate is an axon structure taking the rotary shaft as the shaft center and extending outward along the radial direction of the axon structure.

Description

technical field [0001] The invention relates to a drying tower, in particular to a drying tower with a forward and reverse split flow structure. [0002] The invention also relates to a drying method using a drying tower with a forward-backward split structure for drying. Background technique [0003] During the processing of reconstituted rice, it is necessary to dry and cool the reconstituted rice particles after extrusion and cutting. However, the reconstituted rice granules after extrusion and cutting have higher water content and higher temperature, and the starch component therein will undergo gelatinization under the conditions of high temperature and high humidity, so that the outer surface of the reconstituted rice granules has a higher viscosity. This also resulted in a greater degree of sticking between the reconstituted rice grains. [0004] For the drying of solid granular materials, tower dryers, drum dryers, etc. are often used to take away the moisture of s...
