Abstract
A product on demand delivery system directs product from a main hopper to an application unit. An air pump directs pressurized air to a plurality of air supply hoses. The air supply hoses are coupled to air inlets located on the nozzle assembly of the main hopper. Opposite the air inlets are corresponding product outlets for receiving the air streams and product entrained in the air stream. The product outlets are coupled to product supply hoses that are in turn coupled to auxiliary hoppers located on the application units. The corresponding air inlets and product outlets have baffles extending above the air inlet and outlets. Gaps are formed between adjacent baffles. An agitator assembly having radially extending fingers is located above the baffles. The radially extending fingers extend into the gaps formed by the adjacent baffles.
