Research Progress on Large and Medium-sized Grain Drying Equipment

Grain drying equipment is an important equipment in Chinese agricultural production process, which can significantly improve the quality of grain processing after harvest and reduce the loss rate of mildew and germination during grain storage. At present, the mechanical drying rate of grain in China was only about 30%, and its overall penetration rate still had a great opportunity to improve. The market for grain dryers has great potential for development, and under the encouragement of national policies, the research on the technology, technology and applicability of dryers has been also constantly improved. In recent years, most research on grain drying has focused on process optimization, while there has been less research on grain drying equipment, which has made it difficult to apply excellent process technology and restricted the progress of grain drying equipment. This paper summarized the latest large and medium-sized grain drying equipment and the existing main problems, and put forward some suggestions, which could provide a reference for the research and development of grain drying technology and equipment.
