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.
