Abstract: An apparatus for applying icing to baked goods of any shape, such as cakes, at a flow rate of icing of about 1 gallon per minute (US). The apparatus includes a positive displacement sanitary design gear pump which meets 3A sanitary standards, the pump having symmetrical displacement rotors; an icing reservoir mounted closely adjacent an intake port of the pump, structure for forcing the icing from the reservoir into the intake pump, and tubular discharge pathway extending from the pump to an icing dispensing nozzle assembly. The pathway includes a vertical rigid tubular portion, a relatively short flexible horizontal portion, and a fast-acting positive shut-off valve between the rigid and flexible portions. The icing dispensing nozzle is further provided with an icing flow on-off switch integrating high pressure pumping and the fast acting high pressure positive shut-off valve with the low pressure nozzle valve.
