Abstract: An apparatus for mixing a liquid or pasty product. The apparatus comprises a first housing part (11) and a second housing part (12) assembled together. The assembly of the first housing part (11) and the second housing (12) part forms•—a housing inner space (17) between an inlet (4) and an outlet (5), •—a cooling jacket (7) for circulation of a coolant fluid around the housing inner space (17), and•—a buffer jacket (9) for circulation of a clean fluid, the buffer jacket (9) being formed between the cooling jacket (7) and the housing inner space (17). The buffer jacket protects the mixed product from contamination by the coolant fluid. It also facilitates detection of leakage between the housing inner space and the buffer jacket. The invention also relates to a corresponding method.

Abstract: 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.

Abstract: The invention relates to aerated food products. The aerated food products comprise between 40 wt % and 95 wt % of at least one edible plant paste, especially at least one vegetable paste, and have an overrun ranging from 7% to 150%. The edible plant paste is not a dry particulate or powder composition. The invention also relates to processes for preparing such aerated food products.

Abstract: 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.
