Internal circulation dryer applied to drying and dehumidifying rice and other grains

Abstract

The invention provides an internal circulation dryer applied to drying and dehumidification rice and other grains. The internal circulation dryer comprises a mounting frame body, wherein an overturning and drying device, a feeding mechanism, an air blowing mechanism and a circulating discharging mechanism are mounted on the mounting frame body; the feeding mechanism is used for conveying grains into the overturning and drying device; the air blowing mechanism is used for providing air flow for overturning and drying, the overturning and drying device is used for heating air and conducting hotair overturning and drying treatment on grains with the air as a drying source, and the circulating discharging mechanism is used for receiving the dried grains and conveying the dried grains back tothe overturning and drying device or conveying the dried grains away. The grains are conveyed into a drying tank; hot air is blown into the drying tank in a uniform dispersing and rotating mode through cooperation of a flow stabilizing body and an air direction changing piece, so that grains are dried in the drying tank in a suspension overturning mode, the drying efficiency and effect are better,and the dried grains can be cooled by the first discharging mechanism through the circulating discharging mechanism.

Description

technical field [0001] The invention relates to the field of grain processing, in particular to a grain dryer. Background technique [0002] Grain, such as rice or wheat, needs to be dried before being stored after being harvested. In the prior art, the grain is generally placed on the flat ground to dry, but this will have certain shortcomings. Due to the rainy situation, the grain cannot be dried in time and the germination will occur, which will affect the harvest and cause losses. China is the world's largest grain producer and consumer. According to statistics, due to climate reasons, the grain is too late to be dried or not reached Safe water storage standards cause moldy and germinated grains up to about 5%. Therefore, the inventor has designed a grain dryer, which uses rotating hot air as the drying source and suspending and turning as the drying method to dry the grains. Drying, better drying efficiency and effect, and can effectively ensure that the grains stored ...
