多次试验证明,采用自制富氮储粮机生产的氮气充入粮堆,经膜下循环回风网络,使粮堆氮气浓度达到 95％以上,保持16—20天,可以有效杀死粮堆害虫。并能降低粮堆上层温度,保持储粮品质,可以实现绿色储粮,提高产品附加值。一机两廒氮气防治储粮害虫技术可减少设备用电量,提高经济效益。
Several tests have proved that nitrogen produced by home-made nitrogen-enriched grain storage machines is fed into the grain piles and recycled to the wind network through the membrane to make the nitrogen concentration in the grain piles reach more than 95% for 16-20 days, which can effectively kill the grain piles Pests. And can reduce the temperature of the upper layer of grain piles to maintain the quality of grain storage, which can realize green grain storage and increase the added value of the products. A machine two 廒 nitrogen prevention and control of stored grain pests can reduce equipment power consumption and improve economic efficiency.
