利用冬季低温进行机械通风来降低粮堆温度是粮食储藏的重要技术,但选择适当的通风时机和适宜的通风方式,可以降低通风能耗,减少通风水分损失。试验表明:智能通风能够及时准确地把握有利的通风时机,自动控制通风设备的启停,提高通风效率,降低通风能耗和减少粮食水分损失。 It is an important technology to reduce the temperature of grain piles by using mechanical ventilation at low temperature in winter. However, proper ventilation timing and suitable ventilation mode can reduce the energy consumption of ventilation and reduce the loss of ventilation and moisture. Experiments show that intelligent ventilation can timely and accurately grasp the favorable ventilation timing, automatically control the start and stop of ventilation equipment, improve ventilation efficiency, reduce ventilation energy consumption and reduce grain moisture loss.
