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.
