粮食安全看山东”之临清：“轴流风机压入式通风”助“粮安

Core Viewpoint - The introduction of the "axial flow fan pressurized ventilation" technology in Linqing City significantly enhances grain storage safety and quality while reducing energy consumption and storage losses [1][2] Group 1: Technology Overview - The traditional method of using large fans (7.5 kW) for ventilation in grain storage is inefficient due to high electricity consumption and significant moisture loss [1] - The new technology employs a 1.5 kW axial flow fan to pressurize cool air into the grain pile, effectively lowering temperature and balancing humidity [1] Group 2: Benefits of the New Technology - Energy savings are substantial, with the axial flow fan consuming only 1.5 kW, leading to a significant reduction in electricity usage [1] - The gentle airflow minimizes moisture loss and reduces storage damage, thereby preserving grain quality [1] - The operational process is simplified, saving labor and time costs, which provides an efficient solution for local grain storage [1]
