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 air inlet is downwardly angled relative to the bottom and the product outlet is upwardly angled relative to the bottom. Peaked baffles are located above corresponding air inlet and outlets so that product puddles form beneath the baffles. Gaps are formed between adjacent baffles so that product from the main hopper can flow into the product puddles.
