摘　　要：研究横向谷冷通风技术在平房仓小麦储藏中的应用。实验结果表明:平房仓采用横向谷冷通风技术后,通风路径较传统通风系统增加3倍以上,热交换效率明显提高,冷风量基本不浪费,且谷冷通风降温耗能低,降温后粮堆温度均匀性好。粮堆高度方向粮温基本一致,沿谷冷通风的气流前进方向温度梯度差平均不大于0.5℃/m。在平房仓小麦储藏中应用横向谷冷通风技术可实现与传统竖向谷冷通风相同的降温效果,而且其冷却效率和降温均匀性更好。The application of the technology of transverse ventilation for cooling wheat in warehouse was studied. The result showed that the ventilation path of transverse ventilation was more than treble that of tradition ventilation; heat exchange efficiency was significantly improved; the amount of cold air was not wasted; the energy consumption was decreased; the temperature uniformity inside of the heap was much better. The temperature in the height direction of wheat pile was consistent. The average difference of temperature gradient along the cool air direction was less than 0.5℃/m. The application effect of trans- verse ventilation technology for cooling grain in the warehouse was similar to the traditional vertical cooling ventilation, and the cooling efficiency was higher and the temperature uniformity was much better.
