System for making frozen food article comprises a refrigeration source of high capacity, a food-freezing chamber normally maintained at ambient temperature and of low thermal capacity, a source of food or vegetable juice or puree for freezing, and a controller. The controller controls the refrigeration source to maintain an adequate supply of chilled coolant, controls the discharge of the coolant liquid to a coolant jacket around the frozen food chamber for rapid chilling, controls the discharge of food material to the chamber, controls the beating of the food material while it is freezing, and finally controls the discharge of the resultant beaten frozen food article into a receiving cup.

A system for making a frozen food article, said system comprising: a cooler for providing a quantity of chilled liquid coolant and for circulating the coolant; a freezer having a freezing chamber and a liquid coolant jacket extending around at least part of said freezing chamber, said coolant jacket

A system for making a frozen food article, said system comprising: a cooler for providing a quantity of chilled liquid coolant and for circulating the coolant; a freezer having a freezing chamber and a liquid coolant jacket extending around at least part of said freezing chamber, said coolant jacket being positioned above said cooler; the thermal capacity of said cooler being larger than the thermal capacity of said freezer; means for selectively directing liquid coolant from said cooler into said cooling jacket on said freezer; said cooler having a closed coolant tank; an airbleed line connected from adjacent the top of said jacket to bleed air from said jacket during filling of said jacket with liquid coolant so that said jacket quickly fills with liquid coolant, said bleed line being connected to discharge air from said jacket to said coolant tank; and means for introducing liquid food product into said chamber for freezing in said chamber and means for beating said food material in said freezing chamber so that a beaten frozen food article is formed in said chamber.
