A centrifugal destoned grain microwave drying device

Abstract

The invention discloses a microwave drying device for centrifugal destonerified grain, which belongs to the technical field of grain drying. plate, a feeding hopper located above the middle of the fine stone sieve plate, a microwave generator uniformly fixed on the outer surface of the fixed cylinder, and a grain channel spirally wound from top to bottom and fixed on the outer surface of the outer rotating cylinder. The stone removal channel, the first-level grain channel, the second-level grain channel and the third-level grain channel are arranged in sequence from top to bottom. The half part of the rotating drum facing the outside is all distributed with corresponding openings just for the grain to pass through. The invention has compact structure and ingenious design, can classify and remove stones with different particle sizes contained in the grain, and can ensure that the grain is heated evenly and the drying quality of the grain is ensured.

Description

technical field [0001] The invention relates to the technical field of grain drying, in particular to a microwave drying device for centrifugal destoned grain. Background technique [0002] Dryer refers to a mechanical device that uses thermal energy to reduce the moisture content of materials, and is used to dry objects. The dryer vaporizes and escapes the moisture in the material by heating, generally referring to moisture or other volatile liquid components, in order to obtain a solid material with a specified moisture content. Microwave drying is different from traditional drying methods, and its heat conduction direction is the same as that of moisture diffusion. Compared with the traditional drying method, it has the advantages of high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy automatic control and improved product quality, so it has been paid more and more attention in various fields of drying. The purpose of dryi...

AI Technical Summary

Problems solved by technology

It has the following disadvantages: the drying module is separated from the stone removal module, and the structure is not compact enough; only based on the quality difference between the dried grain and the stone particles, if you want to remove the stone particles uniformly, the removal effect is poor; the drying module structure is simple, The drying quality of the grain cannot be guaranteed. In order to ensure that the grain is evenly heated, it is necessary to use external force to realize the turning operation of the grain.
