THEORY OF OPERATION

(see Figure 2)
A CO cylinder delivers carbon dioxide (CO
2
to the cylinder. The primary CO
inside the Unit and also to two soft drink tanks. CO
carbonator tank and also to product-blender tanks inside the Unit. CO
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 CO
gas pressure also entering the tank. Carbonated water is pushed by CO
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 CO
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.
