The invention relates to an apparatus for aerating a pasty product. The apparatus comprises a housing (1) with an inlet (4) for the pasty product to be aerated and an outlet (5) for the aerated product.

The apparatus comprises at least a first set of a rotor and a stator (21) and a second set of a rotor and a stator (22). The apparatus further comprises a gas injector (6) for injecting, upstream of the first set of a rotor and a stator (21), a gas into the pasty product to be aerated.

The apparatus further comprises an intermediate mixing chamber (7) provided in the housing between the first and the second sets of a rotor and a stator (21,22). A secondary product introduction means protrudes into the intermediate mixing chamber (7) so as to issue into said intermediate mixing chamber (7).

A method for aerating a pasty product is also provided.

A method for extruding a confectionery is provided including supplying a plurality of ingredients to a mixer. The ingredients are mixed to form a confectionery composition in said mixer. Crystals are formed in the confectionery composition while the confectionery composition is in said mixer and the confectionery composition is output from said mixer.

A system for creating an aerated food product, whereby a decreased electrical and thermal load may be obtained is disclosed. Furthermore, a method of producing an aerated food product comprising the steps of separately preparing a first food product portion and a second food product portion, transferring the first food product portion to a first aseptic surge tank, transferring the second food product portion to a second aseptic surge tank, mixing a combination of the first food product portion and the second food product portion to create a mixed food product, aerating the mixed food product to create the aerated food product, and dispensing the aerated food product from a filling apparatus into a container is also disclosed. An aerated food product is also disclosed.

An extrusion device for an ice cream or yogurt machine includes an air delivery channel and a material delivery channel individually extended along a tube body, wherein the air delivery channel and the material delivery channel are arranged for concurrently delivering a flow of air and a flow of raw material. A diameter size of the air delivery channel is smaller than that of the material delivery to match with viscosities of air and raw material.

An apparatus (300) for aerating a food product, (200, 300) comprising a housing (10) with an inlet (100) for the food product and an outlet for the aerated food product, and, within the housing (10), first and second pairs (210, 220, 240) of a rotor and a stator each having complementary toothed rims orientated in opposition in the axial direction, and a gas injector (1) for injecting, at an upstream position relative to the first pair (210, 220) of a rotor and a stator, a gas in the food product to be aerated, wherein a further inlet (310) is provided for injecting, at a position between a pair (210, 220) and an adjacent pair (240) of a rotor and a stator, an additional composition to be mixed with the food product.
