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. A system can include a container mount rotatable in a clockwise and counterclockwise direction, a coolant dosing system configured to provide coolant to ingredients in a container coupled to the container mount, at least one beater to mix ingredients in the container, and a controller to control the rotation of the container mount and the beaters, the controller performing a mixing process that includes rotating the beaters and the container mount in opposite directions for a first time period, rotating the beaters and the container mount in the same directions for a second time period, and rotating the beaters and the container mount in opposite directions for a third time period.
