Abstract
An apparatus (1) for treating food products, comprising a heat exchanger (2) with cylindrical geometry, having a stator (3) and a rotor (4) internal to the stator (3), defining a passage (5) between the stator and the rotor and comprising cooling means (7) active on the outer surface of the stator (3), pumping means (6), for thrusting the food products through said passage (5), means (10) for injecting a fluid inside said passage (5) and means for moving the food products, to cause the emulsion of the fluid with the products by means of a substantially turbulent motion of the products inside said passage (5), together with scraping elements (12) active on the surface of the passage (5).

An apparatus (1) for treating food products, having:
- a heat exchanger (2) with cylindrical geometry, having a stator (3) and a rotor (4) internal to the stator (3), defining a passage (5) between the stator and the rotor and comprising cooling means (7) operatively active on the outer surface of the stator (3);
- pumping means (6), for thrusting the food products through said passage (5);
- characterised in that the apparatus (1) comprises:
- means (10) for injecting a fluid into said passage (5);
- means for handling food products, to produce the emulsion of the fluid with the products by means of a substantially turbulent motion of said products within said passage (5).
Method for cooling and aerating substantially fluid or viscous food products, which provides for the use of a heat exchanger (2) with cylindrical geometry, having a stator (3) and a rotor (4) within the stator and defining a passage (5) between the stator and the rotor, characterised in that it comprises the following steps:
- pumping the food products through said passage;
- injecting air into said passage;
- moving the food products inside said passage, in such a way as to cause a turbulent motion and the emulsion of the air with the products.
