Study on the Effect of Low Power Axial Flow Machine in Winter Cooling and Ventilation of Room Type Rice Barn in Southern Henan
In the process of using room style storage for storing mid to late season indica rice in the southern region of Henan,a low-power axial flow fan phased slow-release cold storage ventilation technology was applied.Eight axial flow fans installed in the bottom air duct of the warehouse were combined with four axial flow fans installed above the eaves wall of the warehouse in a suction ventilation manner.A comparative experiment was conducted to compare the changes in grain temperature and moisture with warehouses using centrifugal fan pressure ventilation.The results show that the cooling effect of axial flow fans is not significantly different from that of centrifugal fans,and the cooling uniformity is better.Using axial flow fans reduces water loss by about 0.11 percentage points compared to using high-power centrifugal fans for ventilation and cold storage.Combined with electricity consumption,water loss,and labor costs,the total loss is reduced by about 16 000 yuan.This study provides new ideas and methods for the renovation of grain storage facilities,and also provides certain data and theoretical support for green technology grain storage.
