THEORY OF OPERATION

(see Figure 2)

A CO2 cylinder delivers carbon dioxide (CO2) gas to an adjustable primary CO2 regulator assembly which is attached to the cylinder. The primary CO2 regulator assembly in turn delivers CO2 gas to adjustable secondary CO2 regulators inside the Unit and also to two soft drink tanks. CO2 is delivered from the adjustable secondary CO2 regulators to the carbonator tank and also to product-blender tanks inside the Unit. CO2 gas pressure pushes syrup out of the soft drink tanks through the syrup sold-out switches, through adjustable syrup flow regulators, through electrically oper- ated syrup solenoid valves, and on to the product blender tanks. At the same time, plain water passes through the water pressure regulator and is pumped into the carbonated water tank by the water pump and is carbonated by CO2 gas pressure also entering the tank. Carbonated water is pushed by CO2 gas pressure from the carbonated water tank, through adjustable carbonated water flow regulators, through electrically operated carbonated water solenoid valves, and on to the product blender tanks. Carbonated water and syrup enter the tanks properly proportioned (blended) for desired BRIX of dispensed product by adjustment of the syrup flow regulators.

From product blender tanks, product is pushed by the CO2 gas into the freeze cylinders. The beater in each freeze cylinder is driven by an electric motor. Scraper blades, attached to the beaters, scrape product from the cylinder walls as product enters the freeze cylinders and is frozen.
