Cross-flow type layered drying machine

Abstract

The invention discloses a cross-flow type layered drying machine, relates to an agricultural product processing machine and belongs to the technical field of agricultural product processing. The cross-flow type layered drying machine aims at solving the problems that when a drying machine is used for drying materials, uneven drying and damage of the cuticles of the materials are easy to occur, the cuticles of the materials are burst when drying temperature is high and the like. The materials enter into the drying machine are separated into material layers with the same thickness due to the fact that baffles with holes are mounted in an intersect-arrayed mode and an inclined mode, self-flow and slow rolling of the materials are achieved by using the self-weight of the materials when hot wind crosses the layered material layer transversely, the cross section position of a moisture-exhaust adjusting plate relative to a moisture-exhaust channel is controlled, drying speed of the materials is controlled, the burst of the material when in a drying process can be avoided. The cross-flow type layered drying machine is simple in structure, high in work efficiency and good in evenness of material drying and can achieve continuous drying operation of the materials. The cross-flow type layered drying machine is suitable for drying operation of granular agricultural products such as dates and walnuts.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a cross-flow layered dryer. Background technique [0002] Drying is an extremely important link in the deep processing of agricultural products such as jujubes and walnuts, which determines the quality and grade of agricultural products. The drying of red dates, walnuts, etc. is mainly done by traditional drying methods, and the degree of factory processing is low. When the traditional drying method is used for drying, it takes a long time, the sanitary conditions are poor, the labor load of manual drying is large, and the process is cumbersome. To solve problems such as skin bursting, a cross-flow layered dryer was proposed, which is of great significance for improving the drying uniformity and quality of red dates and walnuts, and reducing the processing loss rate of red dates.

Problems solved by technology

[0003] Aiming at the traditional drying method, it takes a long time to dry, the sanitary conditions are poor, the labor load of manual drying is large, the process is cumbersome, the material is not dried evenly when drying with a dryer, and the push is easy to cause skin damage, and when the drying temperature is high, the skin of red dates bursts, etc. Problem, designed a cross-flow layered dryer that uses the weight of the material to realize the self-flowing and tumbling process of the drying process
