Spiral type grain circulating electrothermal wind drying device

Abstract

The invention provides a spiral type grain circulating electric hot air drying device, which is characterized in that it includes a bracket on which a drying buffer bin, a discharge bin and an auger conveyor are erected, and the drying buffer bin, discharge bin The bin and the auger conveyor are arranged side by side, and a feed bin is arranged on the dry buffer bin, and a hollow air guide cylinder is arranged in the center of the dry buffer bin, and the hollow air guide column is perpendicular to the bottom of the dry buffer bin And the bottom of the feeding bin, the outer wall of the hollow air guide cylinder is provided with a spiral conveying pipe, and the spiral conveying pipe is a square pipe with a hollow structure. The invention has a simple structure, makes full use of the spiral mode, allows the grain to roll freely on the conveying surface, uses electric hot air to dry each surface of each grain in the rolling, fully dries the moisture in the grain, and improves the drying efficiency of the grain. Increase the shelf life of grain.

Description

technical field [0001] The invention relates to the technical field of crops, in particular to a spiral type grain circulation electric hot air drying device. Background technique [0002] Moisture is an important chemical component in grains. Moisture in grains not only has a great influence on the physiology of seeds, but also has a great influence on the processing and storage of grains and the value of grains. If the harvested grains are not dried in a timely manner, the grains tend to become soft and have a slight musty smell, and then the chaff is wet and grayed, turning white, and aflatoxin is produced, which can be poisonous or even fatal to people after eating. The existing grain drying devices dry the grains by free-falling and stacking them at the bottom of the drying bin. This drying method has a small area of ​​contact with each grain, and there is no way to fully dry each grain, and the drying efficiency is not high enough. In addition, there is also a device ...

Problems solved by technology

If the harvested grains are not dried in time, the grains tend to become soft and have a slight musty smell, and then the chaff is wet and dusty, turning white, producing aflatoxin, which will be poisoned and even fatal after human consumption

The existing grain drying devices dry the grains by free-falling and accumulating on the bottom of the drying bin. This drying method has a small area of ​​contact with each grain, and there is no way to fully dry each grain, and the drying efficiency is not high enough.

In addition, there is also a device for heating and drying on the transmission surface, which is only provided with a heating plate on the transmission surface, so that the rice can only be heated on one side, not only the heating effect is poor, but also the moisture emitted by the heating cannot be volatilized in time If it is drained away, it will seriously affect the efficiency
