Internal and external rotary type grain damage-free dryer

Abstract

The invention discloses non-damage dryer suitable for grains with different grain diameters. A hollow cylindrical rotary drum is arranged, a first gear and a second speed reducer are arranged at the left end of the outer side face of the hollow cylindrical rotary drum, a second gear meshing with the first gear is arranged on an output shaft of the second speed reducer, a second motor is arranged at the end, close to the second speed reducer, of the upper surface of a second supporting plate, and an input shaft of the second speed reducer is connected with the output end of the second motor. The internal and external rotary type grain damage-free dryer is compact in structure, convenient to operate, small in occupied space in the using process, capable of rapidly conducting drying treatmenton the various types of grains, arrangement of an air suction nozzle facilitates collection of dust, arrangement of a vacuum material suction pump facilitates feeding of the grains, arrangement of locking universal wheels combined with a collecting box facilitates collection and transportation of the dried grains, and the drying time is controlled through the relative rotating speed of a screw rod and a hollow cylindrical rotating cylinder.

Description

[0001] This application is a divisional application of the Chinese patent application 201810397878.1 filed on April 28, 2018, entitled "A Non-Injury Dryer Applicable to Grain with Different Particle Sizes". technical field [0002] The invention relates to the technical field of grain dryers, in particular to an inner and outer rotary grain dryer without damage. Background technique [0003] As we all know, when the temperature and humidity conditions in the environment where the food is located meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of microorganisms such as mold in grains. Usually, controlling the moisture content of grains below the safe moisture level can effectively prevent grains from going moldy. At present, the method for reducing grain moisture is the natural drying method. In the main grain producing areas, due to the large output and insufficien...

AI Technical Summary

Problems solved by technology

In the main grain producing areas, due to the large output and insufficient drying space, the moisture of the grain purchased by the grain depot often exceeds the safe moisture content. Regular drying can ensure that the grain does not go moldy. Due to the limitation of the drying place of the grain depot, the grains stored in the warehouse are often not able to be dried on time, resulting in mildew of the grain in the grain depot. Although the existing dryer can dry the grain, but The following problems still exist: (1) The types of grains that can be dried by the same type of dryer are limited. When drying different types of grains, it is often necessary to adjust the internal structure of the dryer, which increases the labor in the drying process. (2) The existing dryer cannot continuously dry the grain, and the drying efficiency is not very high
