Drying machine

Abstract

The invention provides a drying machine. The drying machine comprises a feeding device, a drying device and a cooling device which communicate with one another in sequence; the feeding device comprises a feeding hopper and a plurality of nozzles, wherein the nozzles are formed in the bottom of the feeding hopper; the drying device comprises a first inner sleeve and a first coating layer, wherein the first inner sleeve is coated with the first coating layer, an inlet and an outlet are formed in the first coating layer, a plurality of guiding parts extending inwards in the radial direction is arranged on the first coating layer, and a plurality of holes are formed in each guiding part; and the cooling device comprises a second inner sleeve and a second coating layer, and the second inner sleeve is coated with the second coating layer. By sequentially arranging the feeding device, the drying device and the cooling device which communicate with one another, the first inner sleeve is coated with the first coating layer which is provided with the multiple guiding parts, the guiding parts extend inwards in the radial direction, and the second inner sleeve is coated with the second coating layer, so that heating area of materials is increased, the drying process of the materials is quickened, the water content of the materials is reduced, the structure of the drying machine is simplified, and drying cost is reduced.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a drying machine. Background technique [0002] Drying is the process of removing moisture from various materials. Various materials can be solid, liquid or gas, and solid can be divided into bulk material, fiber material, granular material, etc. The wetness in the material generally refers to water, and it can also be other solvents. Drying methods usually include mechanical dehydration, heat drying and chemical dehumidification. Chinese patent CN101456829B introduces a drying process of sodium lauryl sulfate, which includes a spray drying part and a vacuum scraper drying part, but through the drying device of this kind of structure, the drying effect of chemical materials is relatively poor, and the drying device The structure is complicated, and the drying cost is high; moreover, the chemical materials after drying cannot be cooled. [0003] In view of this, it is necessary ...
