ABSTRACT:
A dispenser for frozen soft serve confections comprises a refrigerated dispensing cabinet. One or more rigid cartridges containing frozen soft serve confection are releasably mounted within the interior of the dispensing cabinet. Each cartridge uses compressed air to urge the frozen confection from the cartridge through a valve assembly. A valve assembly comprises a valve body that defines a passageway that connects an inlet opening at the cartridge with an outlet opening outside the dispensing cabinet. A valve for alternatively blocking or permitting flow of frozen confection through the passageway is provided at the outlet opening. The valve can include a piston that is moved between the opened and closed positions by a lever. The valve can also include an inflatable bladder that is alternatively inflated or deflated by compressed air that flows through a push button switch. When inflated, the flow of frozen confection is prevented and when deflated, flow is permitted. If a bladder valve is used, a leak detection system senses any leak in the compressed air system and operates a pressure switch to simultaneously block further flow of compressed air to the cartridge and depressurized the cartridge to prevent the contents of the cartridge from spilling.
