Abstract: A sealed pressurized food dispensing system with self-cleaning features that can include a freezing barrel, a faceplate defining a dispense bore and a cleaning bypass passage passing through the faceplate and having an open end, where the dispenser can also include a valve stem that may be moved between a dispensing position and a non-dispensing position where the cleaning bypass passage is positioned such that, when the valve stem is in its non-dispensing position, no fluid path exists between the interior of the freezing barrel and the open end of the cleaning bypass passage within the faceplate.

Abstract: A food product dispenser including a cabinet; a freezing cylinder for freezing a food product located within the cabinet; an evaporator including a fluid path that generally encircles the freezing cylinder and that has an evaporator inlet and an evaporator outlet; a compressor located within the cabinet at a location below the freezing cylinder and having an inlet being fluidly coupled to the evaporator outlet; a condenser at least partially positioned between the compressor and the evaporator, where the condenser has an inlet is fluidly coupled to the compressor outlet; a variable flow expansion valve located within the cabinet and having a first inlet fluidly coupled to the condenser outlet and a first outlet fluidly coupled to the evaporator inlet and a second expansion valve located within the cabinet having a second inlet fluidly coupled to the condenser outlet and a second fluid outlet coupled to the compressor inlet, where the second variable flow expansion valve being located within the cabinet at a l

Abstract: A sealed pressurized food dispensing system with self-cleaning features that can include a food processing apparatus that includes a cylinder having an inlet for receiving a food ingredient; a faceplate coupled to the cylinder, that defines a dispense bore and a bypass passage having a first open end; a blocking cap coupled to the faceplate to block the dispensing of product from within the cylinder; and a pump having an inlet fluidly coupled to a connection element and an outlet fluidly coupled to the inlet of the cylinder, where connection of the connection element to the source of cleaning fluid will result in the pumping of cleaning fluid into the food dispensing cylinder, though the cylinder into the blocking cap, and through the blocking cap into the bypass passage.

Abstract: The present disclosure provides an improved system and method that includes a food dispensing machine for dispensing a base food product through a dispensing valve and adding ingredients and other additives, such as flavors and the like, to the base food product when the product is dispensed from a product chamber. Apparatuses and methods for maintaining a consistent mix of the base product in the freezing chamber are disclosed as are processes for calibrating desired proportions of ingredients.

Abstract: An improved beverage dispensing system includes a main system structure and an improved dispensing structure. The main system structure includes a freezing chamber for freezing a food item to be dispensed by the system and elements for conveying the unfrozen food item into the freezing chamber, for freezing the food item within the chamber and maintaining the overall proper operation of the system. The food item to be dispensed by the main system structure may be a frozen carbonated beverage. The improved dispensing structure that operates such that the venturi effect will create a pressure differential across a venturi insert tending to pull (or push) dispensed product through a venturi insert and out of the dispensing portion of a faceplate.
