Abstract A method for producing frozen confections such as ice cream, or the like, wherein liquid mix is delivered from a storage tank through a freezing chamber to a draw-off valve from which the frozen mix is dispensed to cones or cups. The method is characterized by a mix tank arrangement which utilizes disposable flexible bags removably confined within a rigid container which arrangement eliminates the necessity of returning mix tanks to the dairy for sterilization and refill. The method is further characterized by a mix tank arrangement which utilizes a gaseous propellant to agitate the mix as well as to propel the mix through the machine thereby achieving homeogeneity of mix without the need for special shaking machines.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
125 words
The steps in the method of dispensing soft ice cream or the like, said method comprising, positioning a refrigerated sanitized flexible bag of mix in a rigid tank means, said tank means including walls for confining said flexible bag thereby preventing rupture thereof during subsequent pressurization; delivering pressurized gas through an inlet having at least one opening communicating with said bag to pressurize the mix therein; releasing said pressurized mix from said bag to the inlet of a heat exchanger means to chill the mix and thereby stiffen its state; sequentially releasing portions of said chilled mix from said heat exchanger means; and replacing said flexible sanitized bag of mix with another filled flexible sanitized bag when the supply in said first bag is exhausted.
Claim 2
Dependent Claim
125 words
The steps in the method of dispensing soft ice cream or the like, said method comprising, positioning a refrigerated sanitized flexible bag of mix in a rigid tank means, said tank means including walls for confining said flexible bag thereby preventing rupture thereof during subsequent pressurization; delivering pressurized gas through an inlet having at least one opening communicating with said bag to pressurize the mix therein; releasing said pressurized mix from said bag to the inlet of a heat exchanger means to chill the mix and thereby stiffen its state; sequentially releasing portions of said chilled mix from said heat exchanger means; and replacing said flexible sanitized bag of mix with another filled flexible sanitized bag when the supply in said first bag is exhausted.
Claim 3
Dependent Claim
24 words
The method according to claim 1 wherein the flexible bag includes an inlet provided with orifice means which release mixing gas within the mix.
