离心风机通风技术,因其具有通风时间短,降温、散湿速度快等特点,在我国南方粮食储藏和处理高水分粮中被广泛采用。但该技术也存在着能耗高,安装繁琐,水分减量大等缺点,增加了储粮的水分损耗。我库通过对山墙轴流风机的改造,采用高压低功率的轴流风机,于2005年10月至2006年1月进 Centrifugal fan ventilation technology, because of its short ventilation time, cooling, fast wet and other characteristics, in southern China’s grain storage and processing of high moisture food is widely used. However, the technology also has the disadvantages of high energy consumption, cumbersome installation, large water reduction and the like, and increases the moisture loss of grain storage. Through the renovation of the gable axial fan, our warehouse adopted the high-pressure and low-power axial fan, from October 2005 to January 2006
