Research Status and Prospect on Green and Low-Carbon Technology of Grain Drying

Grain drying is a critical element in the production chain and plays a key role in ensuring national food security. However, the progress of the drying industry toward high-quality development is hampered by outdated dying techniques that lack effective measures for carbon reduction and emissions. This study began by examining the current technological landscape of mechanized grain drying. It systematically analyzed the main factors contributing to high energy consumption and grain losses during drying, including the heating mode of the drying system, the design of the drying process, and the control technology used, and provided a comparative evaluation of mechanized drying processes and methods for energy-saving improvements. In addition, this study reviewed the development of drying theory and intelligent control, and explored the characteristics and progress of intelligent grain drying technology. Notable issues in grain drying intelligence were identified, including challenges related to information perception, imprecise algorithms, and reliance on singular control strategies. To address these challenges, the study proposed suggestions for the future development of the industry, including paradigm-shifting innovations in grain drying theoretical research, optimization of drying equipment design and processes, and the establishment of a system of intelligent control methods for drying. These suggestions aim to guide technological innovation towards energy-efficient and emission-reduced grain drying, and provide valuable insights for the high-quality development of the industry.
