地下通风槽需要在建仓时就一并设计好 ,但不少粮仓因建仓时间较早 ,没有设计地下通风槽而普遍采用地上笼或地面堆码通风道 ,在储粮通风、降温去湿时效果不太理想 ,特别是在高温、高湿气候条件下对新入仓或表层结露的储粮进行降温、降湿 ,就更难达到理想效果。针对上述情况 ,如 Underground ventilation slots need to be designed together when the Jiancang, but many warehouses because Jiancang time earlier, there is no design of underground ventilation slots and the ground cage or ground stacking ventilation, ventilation in the grain storage, cooling effect when wet Not ideal, especially in high temperature, high humidity conditions on the new warehouse or surface condensation of grain storage for cooling, dehumidification, even more difficult to achieve the desired effect. For the above situation, such as
