Abstract: Systems and methods of producing a frozen food product include mixing ingredients with a liquefied gas, e.g. liquid nitrogen. The texture and quality of the food product may be determined by sensing temperature or viscosity, and controlling the rate at which the liquefied gas flows into the mixture, i.e. dosing. This functionality may be achieved using one or more scoops, the position of which may be controlled by actuators. The dosing may be controlled by a program that receives input from one or more sensors, and the program may be responsive to input of the type or amount of ingredients being mixed. In addition, the dosing may be controlled by a human being through a user interface, e.g. by pushing a ‘dose’ button.

Abstract: Systems and methods of producing a frozen food product include dosing ingredients with a liquefied gas while mixing the ingredients using self-cleaning interlocking beaters. The beaters are optionally also disposed to clean a container in which the ingredients are frozen. The rate and amount of cooling is controlled by measuring the quantity of liquid nitrogen, measuring viscosity of the frozen food product, measuring temperature, and/or the like.
