A dispensing system and method for moving a confectionery mixture having a predetermined ratio of air to fluid to a freezing cylinder comprises a multiple portion tube containing the confectionery mixture, an air meter for controlling the ratio of air to fluid in the mixture, and a peristaltic pump for pumping the confectionery mixture through the tube. The peristaltic pump is positioned between a reservoir and the freezing cylinder and the tube is routed through the pump to form a generally U-shaped trough. When the pump is idle, some of the confectionery mixture settles in the generally U-shaped tube to form a liquid which prevents air from back flowing from a pressure side to a suction side of the pump. Accordingly, the consistency of the confectionery product is maintained when the pump is idle. The peristaltic pump also includes a proximity switch which prevents the pump from operating until all of its movable parts are properly secured.
A confectionery dispensing system for moving a confectionery mixture having a predetermined ratio of air to fluid to a freezing cylinder, comprising:
A method for use in a confectionery dispensing system for moving a confectionery mixture having a predetermined milo of air-to-fluid and for maintaining said predetermined ratio of air-to-fluid in said confectionery fluid, said confectionery dispensing system having a reservoir containing a confectionery fluid, a freezing cylinder for dispensing said confectionery mixture, a tube connecting said reservoir to said freezing cylinder, an air metering means connected to said tube and a peristaltic pump having an operating mode and an idle mode and being connected to said tube so that there is a suction side of said pump and a pressure side of said pump, said method comprising the steps of:
