Product, such as grain, is cleansed of particulate, such as dust, as it is being conveyed in the normal receiving, storage, and shipping processes. The particulate is sucked from the product by large volumes of low velocity air. The particulate is sucked from the product at a time that the product is near a port in the side of a discharge transition of the conveyor. It is sucked at the discharge transition because at that point, the grain is in motion and agitated, as well as being near the walls of the conveyor. Furthermore, the conveying of product will create a wind or movement of air which airs the sucking of the particlate from the product. The fan causing the suction is placed as near as possible to the conveyor so that the air and particulate, once removed, is moved through the particulate pipes under pressure rather than under suction. Also, all of the particulate pipes carrying the particulate and air are at an angle greater than 55.degree. to horizontal, the angle of repose for dust in the particulate pipes. The particulate is separated from the air in a large diameter bin which is also used to store the particulate until its removal from the particulate bin.
The method of cleaning particulate from grain as the grain is being conveyed in closed conveyors having existing air therein and suspended flow at a location, comprising the steps of:
