根据拟通风降温的散装粮储量、粮堆平均温度、风网总通风量及通风期间的大气温度条件、对通过地槽或地上通风笼进行降温通风时,达到预定通风目的所需的通风时间进行了定量的理论分析,推导出通风所需时间的计算公式,供降温通风时参考。
According to the amount of bulk grain storage to be ventilated and cooled, the average temperature of the grain pens, the total amount of ventilation in the wind net and the atmospheric temperature during the ventilation, the ventilation time required for the purpose of ventilating for the purpose of ventilation for ventilation through the ground trough or above-ground ventilation cage The quantitative theoretical analysis deduces the formula for the time required for ventilation, for reference when cooling ventilation.
