摘要:
An apparatus for producing and dispensing an aerated frozen confection in which a pump is mounted in the liquid ingredients reservoir of th e apparatus and operates to pump a mixture of air and liquid ingredients, in selected proportions, to the freezer compartment of the apparatus. The pump itself is responsive to pressure within the freezer compartment to regulate the volume of mixture supplied to the freezer compartment by the pump for enabling automatic replenishment of the aerated mix in the freezer compartment. The pump includes a plunger projecting into the freezer compartment and driven by a cam which rotates with an agitator in the freezer compartment to move the plunger against the bias fo a spring in the pump so as to reciprocate the plunger until the pressure within the compartment is great enough to move the plunger away from the cam, against the bias of the spring, thereby discontinuing the supply of mix to the freezer compartment.
摘要:
A process for making a protein stabilizer for an edible, frozen foamed emulsion in which proteins are modified by co-drying the protein with a selected emulsifier.
摘要:
frozen aerated gelatin mix is prepared by dissolving a gelatin mix in water, cooling the dissolved mix while agitating and aerating the mix, shaping, then freezing the mix to a core temperature less than 10°F (-10°C). This frozen aerated composition is ready-to-eat at freezer temperatures, while providing a smooth and creamy texture, but without excessive gummy or icy characteristics.
摘要:
An ice-cream making machine, comprises a receptacle (16) for receiving the liquid ingredients to be used for making the ice-cream. A cooling duct (8) conveying the ingredients from the receptacle (16) to an ice-cream outlet (28) of the machine, and a rotor including a plurality of blades (24) rotatably driven within the cooling duct (8) and effective to atomize the liquid ingredients as particles mixed in in air and to direct them against the wall of the cooling duct (8) for instant freezing. The cooling duct (8) also cools the receptacle (16) to a temperature below ambient but above 0°C to prevent spoilage of the ingredients and also to pre-cool the ingredients before being frozen in the cooling duct (8).
