全国粮食系统劳动模范,浙江省兰溪县永昌粮管所长俞长庚同志,最近改制成功一种灵巧轻便的电动吸粉螨器,经现场操作使用,效果良好.这种电动吸粉螨器,使用时只要打开电源开关,将吸粉螨管插粮堆表层扒动,就能很快将粉螨吸进管内消灭. National food system model workers, comrade Yu Changgeng, director of Yongchang, Lanxi County, Zhejiang Province, recently succeeded in reshaping a kind of dexterous and portable electric dust-absorbing mite by operating on the spot, which worked well. As long as the power switch is turned on, the suction mite pipe piles into the surface of the pile grilled, you can quickly powder mites sucked into the tube to eliminate.
