摘要
在对大豆进行冬季通风作业时,采用正压上行压入式、负压下行吸出式和先负压后正压三种作业方式分阶段进行通风,充分的利用自然冷源,达到降温目的,通过对比三种作业方式的降温效果、水分损耗、降温能耗、人工投入等,并根据粮情,找出最合适的通风方式。
This paper is based on experiments in soybean ventilation in winter, ventilation is operated in three ways： upward positive pressure type, downward negative pressure type, and positive pressure after negative pressure type. Through the comparison of three kinds of operation modes in cooling effect, moisture loss, energy consumption, labor input and according to the grain condition, find out the most appropriate ventilation operation mode.
