摘　　要：为提高干燥品质、减轻劳动强度和实现干燥过程自动化 ,研制了基于单片机控制的气流换向干燥系统。采用“小参数热风渗流、间接加热、气流换向深层干燥”的干燥工艺 ,对系统的性能进行了试验研究和分析 ,同时 ,对气流换向及气流内循环在干燥中的作用和效果进行了讨论。结果表明 ,气流换向干燥系统和所采用的干燥工艺能有效地保证干燥物料 。In order to improve drying quality, reduce manpower intensity and realize automatic drying, a reversible airflow drying system based on single chip computer control was developed. Utilizing the technological process, 'reversible airflow and deep bed drying indirectly', the performance experiments and analyses of the system were carried out. The function and effect of the inverse air current and the inner outer air current cycle in the drying process were discussed. By using the system and the technological process, the qualities of the dried materials, seeds especially, can be ensured effectively.
