Description

Drum-type grain drying device

Technical Field

The utility model belongs to the technical field of the grain is dried, especially, relate to a drum-type grain drying device.

Background

China is always a big agricultural country, and agricultural production is a main source of income of farmers. Most grain crops have no post-mature period, are already physiologically mature at the time of harvesting and have the germination capacity. Meanwhile, the water absorption required by the grain crops for sprouting is low. Therefore, when the grain crops are harvested, if the grain crops are not harvested, threshed and completely dried in the sun in time even in rainy days, the grain crops can germinate in the field and the field. The grain crop in storage is easy to sprout even if it is condensed, rewet or rained. The grain crops are not threshed and completely dried in the sun in time, and the grass is stacked and easy to rett to yellow. The quality and the storage stability of the sprouting and retting grain crops are greatly reduced. The grain crops are not resistant to high temperature, the grain crops which are over summer are easy to age, and the phenomenon of 'waist burst' is easy to occur in the grain crops which are exposed to the sun in burning sun or the grain crops which are suddenly cooled after being exposed to the sun. When the temperature drops soon after the new grain crops are put into a warehouse, the moisture on the surface of a grain pile is often condensed to increase the moisture of the grain on the surface layer, so that the grain is not stored, and the moisture of the grain stored on the surface layer is timely reduced. Ensuring the quality of grain crops in storage: grain crops with large water content, more impurities and more imperfect grains are easy to generate heat and mildew and are not stored durably. Therefore, the improvement of the quality of the grain crops in storage is the key of the safe storage of the grain crops. The new grain crop has vigorous respiration, mild grain and high water content, and should be ventilated, cooled and dewatered at proper time. The traditional method is mainly used for dehumidifying grains by paving the grains on the ground and utilizing the sun, and the method is time-consuming, labor-consuming and low in efficiency.
