APPARATUS AND PROCESS FOR PRODUCING ICE CREAM OR SIMILAR FOOD PRODUCTS

摘要

A process for producing ice cream and other similar food products is described, comprising the steps of: a) providing a base preparation for ice cream or dessert or similar; b) nebulizing the base preparation through at least one first nozzle, and c) intercepting the jet of the base preparation with at least one jet of preferably cryogenic expanding coolant to obtain the ice cream. It is further described an apparatus for the production of ice cream or similar food products, comprising: - at least one first nozzle; - means for feeding said at least one first nozzle with a base preparation for ice cream or dessert or similar, at a first nebulization pressure; - means for intercepting the jet of base preparation exiting from said at least one first nozzle with an expanding coolant. Preferably the nebulization of the base preparation is obtained using compressed air as propellant gas and the aerosol cooling is carried out with expanding CO2. More preferably the CO2 expansion is isentropic and supersonic or transonic and it happens through convergent-divergent nozzles.
