Using method of spiral type crop circulation electric hot air drying device

Abstract

The invention relates to a using method of a spiral type crop circulation electric hot air drying device. The using method is characterized by comprising the steps that S01, a fan, an electric heating wire and an exhaust fan are started, hot air is conveyed into a drying temporary storage bin through air holes in the conveying face of a spiral conveying pipe, and normal-temperature air in the drying temporary storage bin is exhausted out through the exhaust fan so that the drying temporary storage bin can be filled with the hot air; S02, a first batch of crops are poured into a feeding hopper, an auger conveyer is started, the crops are conveyed into a feeding bin through the auger conveyer and freely fall on the conveying face of the spiral conveying pipe, and the crops freely fall on the conveying face from top to bottom under the action of gravity; and S03, a vibrator is started and drives the spiral conveying pipe to vibrate, the crops can be prevented from being stuck on the conveying face, and the falling speed of the crops can be increased. The method fully utilizes the spiral mode, all faces of all the rolling crops are dried through the electric hot air, the crops are fully dried, and the crop drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crops, in particular to a method for using a spiral 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 method is to 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 side of the grains, and the drying efficiency is low. In addition, ther...

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 method is to dry the grain 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 side of the grain, and the drying efficiency is low.

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
