Additionally, the venturi port has a product inlet coupled to the air passage. The distrib ution manifold also has a bypass port which has a top surface, a bottom surface, a front bypass surface, and a rear bypass surface. The bypass port has a product throughway connecting the front bypass surface and the rear bypass surface. A wall of the bypass port define s a passage from the top surface to the bottom surface for insulating the passage from f luidcommunication with the product throughway.</p> |
