| 为探索降温减损、提质增效的储粮新技术，采用设计仓容10 000 t浅圆仓，研究浅圆仓中心管径向通风对进口大豆的应用效果，并与常规通风（地槽吸出式下行通风和压入式上行通风）进行对比，综合分析通风方式对同一产地进口大豆的通风作业效果、水分损耗、作业能耗等的影响，验证中心管径向通风的可行性和实用性。结果表明：中心管径向通风对粮堆中圈区域降温效果不明显，在通风作业136 h后关闭径向风机，仅通过地槽风机进行吸出式通风，降温效果得到改善；中心管径向通风时间为272~403 h，平均粮温降幅为1.9~4.0 ℃，平均水分降幅约0.2百分点，常规通风通风时间为151~189 h，平均粮温降幅为1.0~2.7 ℃，压入式上行通风平均水分降幅为0.05百分点，吸出式下行通风平均水分降幅为0.10百分点；中心管径向通风能耗为5 062.5~6 615 kW·h，仅1个仓产生人工费用；常规通风能耗为2 265~2 835.0 kW·h ，人工费用为 1 250~1 500元。综上，与常规通风相比，中心管径向通风解决了中心杂质聚集区通风效果不佳的问题，且节省人工费用，但对粮堆中圈区域降温效果不明显，另外中心管径向通风通风时间相对较长，能耗较高。 |

| To explore new grain storage technologies for cooling, reducing losses, improving quality, and increasing efficiency，using the squat silos with designed capacity of 10 000 t, the application effect of radial ventilation with central pipe on imported soybean was studied, and it was compared with the conventional ventilation(suction downward ventilation and press-in upward ventilation).The effect of ventilation methods on the ventilation operation effects, moisture loss, and work energy consumption of imported soybeans from the same origin was comprehensively analyzed, and the feasibility and practicality of radial ventilation with central pipe were verified.The results showed that the radial ventilation with central pipe had no significant cooling effect on the central area of the grain pile. After 136 h of ventilation operation, the radial fan was turned off and only the suction ventilation through ground gutter was carried out, which improved the cooling effect.The ventilation time, average decrease in grain temperature and average decrease in moisture content of radial ventilation with central pipe were 272-403 h, 1.9-4.0 ℃ and about 0.2 percentage points,respectively, while those of conventional ventilation were 151-189 h, 1.0-2.7 ℃ and 0.05 percentage points(press-in upward ventilation) and 0.10 percentage points(suction downward ventilation), respectively. The energy consumption of radial ventilation with central pipe was 5 062.5-6 615 kW·h, and only one silo incurred labor costs, while the energy consumption of conventional ventilation was 2 265-2 835.0 kW·h, and the labor cost was 1 250-1 500 yuan. In conclusion, compared with the conventional ventilation, the radial ventilation with central pipe solves the problem of poor ventilation effect in the central impurity accumulation area and saves labor costs, but the cooling effect on the circular area of the grain pile is not significant. In addition, the radial ventilation time with central pipe is relatively long and the energy consumption is high. |
