Description

A grain drying device for agricultural production

technical field

The invention relates to the technical field of grain drying, in particular to a grain drying device for agricultural production.

Background technique

Food security is not only a major issue related to the national economy and people's livelihood, but also a prerequisite for ensuring the steady growth of the national economy and building a harmonious society. Grain, as the most important type of grain, is an important strategic material reserve. The stored grain needs to be dried before it can be put into storage. The drying process can effectively prevent rice mildew. In recent years, the grain output has been increasing continuously, and the degree of agricultural automation is getting higher and higher, but the efficiency, mechanization and automation of grain drying equipment are not high. Increasing grain production involves not only planting and harvesting, but also drying and storage. However, grains such as rice will cause losses in the drying, drying, threshing, storage, transportation, processing, consumption and other links after harvest. Every year, rice mildew, germination and other losses caused by failure to dry in time after harvesting are relatively large. During the grain harvest season, large quantities of grain after harvest must be dried in a timely manner. In recent years, with the development of the grain industry, research on grain drying has also made a lot of progress. Compared with traditional natural drying, mechanized grain drying can meet the requirements of mass production to a greater extent, and reduce grain loss through process parameter settings to ensure the quality of grain drying.

Hot air drying equipment is the most widely used mechanical drying equipment for grain drying technology. This equipment generally uses a certain amount of hot air to take away moisture from the surface of the material to achieve the purpose of drying. When stacking, it is difficult to fully dry the grains, and the drying efficiency is low, which needs further improvement.
