A softserve product refrigeration and dispensing machine (1) having numerous novel features to make the machine and the operation thereof more efficient; a novel supply method and apparatus provides raw product mix and gaseous matter at the proper ratios to the freezing cylinder (17) of the machine. Additionally, and also in conjunction with a novel door and product dispensing apparatus (40, 40a), the special design features enable the maintenance of a dispenser (60), beater (110), freezing chamber and other parts of the machine capable of easy flushing with a cleaning and/or sanitizing solution via the supply method and apparatus without requiring machine disassembly with no retention of the food stuffs and the like.

1. A soft serve product refrigeration and product dispensing machine comprising a refrigeration cycle including, in a closed refrigerant path, a serially connected evaporator including a freezing chamber for product mix, a refrigeration compressor, condenser and expansion valve; a container capable of pressurization, and means configured to deliver, at different times, one of a product mix and cleaning and/or sanitizing solution to the freezing chamber at a rate dependant upon the pressure applied to said container; said freezing chamber including a product mix or cleaning and/or sanitizing solution entry and product mix and cleaning and/or sanitizing solution dispensing valve forming an exit therefor, and a dasher assembly in said freezing chamber for mixing the product mix or agitating the cleaning and/or sanitizing solution while effecting movement thereof from the inlet to said dispensing valve;a control system for controlling the operation of at least the refrigeration cycle, and the pressurization of said container whereby, upon command, said control system causes supplying, from the container, said cleaning and/or sanitizing solution thereby permitting cleaning in place of said freezing chamber, dispensing valve and said dasher assembly.
