ABSTRACT:
Small batches of grain for household use are vacuum cleaned in a portable apparatus which can receive vacuum power from the hose of a household vacuum cleaner. Grain requiring cleaning is introduced into the device through a transparent top door and gravitates into a hopper within the apparatus having a restricted grain outlet. When suction is applied through the housing of the apparatus which is vented to atmosphere, air and uncleaned grain are propelled continuously on a circuitous path until the desired clean state of the grain can be observed through the transparent door, at which time another door of the device is opened to permit clean grain to pass into a holding chamber. A waste chamber is also provided in the apparatus and is separated by a screen from the main treatment chamber.
