[0019] Instructions for use: When the raw materials and finished products of grains, agricultural and sideline products, and roasted nuts fall on the screen surface 15 for impurity removal, the generated floating particles such as dust are sucked into the impurity removal chamber 13 from the feed pipe 7.
