Device and method for dosing cryogenic liquid

A method of making a frozen confection during a mixing process controlled by a controller configured to separately control the direction of rotation, and the duration of rotation, of (a) a container mount coupled to a container and (b) at least one beater extending into the container, the method comprising:

• placing ingredients for the frozen confection in the container;
• rotating the container via rotation of the container mount in a first direction, and rotating the at least one beater in a second direction for a first period of the mixing process to mix ingredients in the container to form a mixture, wherein the first direction and the second direction are opposite directions, and wherein the duration of the first period is controlled by the controller;
• dosing the ingredients with a controlled amount of coolant from a coolant dosing system intermittently to cool the mixture within the container;
• once a predetermined viscosity is reached to form a frozen or semi-frozen mixture of the ingredients, changing the direction of the container mount or the at least one beater to rotate both the container mount and the at least one beater in the same direction momentarily to cause pillars of the ingredient mixture, that have risen up inside portions of the container due in part to interactions of the mixture with the sides of the container and the at least one beater, to be pulled back down into the container to aid in the formation of a smooth and consistent frozen confection;
• rotating the container mount and/or the at least one beater, whichever has switched direction, in its original rotation direction;
• and
• this counter-to-uniform rotation cycle is continued throughout the mixing process to avoid re-emergence of the pillars and to create a seamlessly frozen confection automatically without the need for human intervention.
