Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, in particular to a grain dryer. Background Art

[0002] In agricultural production, grain drying is a key link to ensure the quality of grain storage. Traditional natural air drying methods are greatly restricted by weather conditions, have a long drying cycle, and are prone to causing grain mildew and quality degradation. Mechanical drying technology has gradually become the main means of grain drying due to its advantages such as high efficiency and strong controllability. However, existing grain dryers have problems such as high energy consumption, uneven drying, and complex operation, which affect their promotion and application.

[0003] In recent years, with the development of agricultural science and technology, new technologies such as low-temperature circulation drying and heat pump drying have emerged, providing new ideas for the improvement of grain dryers. These new technologies can not only effectively reduce energy consumption, but also better protect the quality of grain and reduce cracking and breakage. At the same time, the application of intelligent control technology has further improved the convenience of operation and drying accuracy of grain dryers. Utility Model Content
