Process for the manufacturing of frozen aerated products

摘要

Frozen aerated products are produced by i) providing two separate forming elements, ii) providing at least one open cavity on a surface each forming element, iii) providing filling devices for filling said cavities with a frozen aerated material, iv) filling two cavities, one on each moulding surface, with a frozen aerated material, wherein at least one of the cavities is filled with a frozen aerated product having an overrun of between 30% and 130%, this product is then allowed to expand outside its cavity, the two cavities are then moved opposite one another and the frozen aerated product in each cavity is pressed against the frozen aerated product in the other cavity.

1. Process for the manufacturing of frozen aerated products comprising:
providing two separate forming elements which are a pair of parallel rollers each having internally a roller cavity, providing at least one open mould cavity on a surface of each forming element, providing filling devices for filling said mould cavities with a frozen aerated material, and a. cooling said surface of each forming element to a temperature below −80° C. by introducing a refrigerating medium into the roller cavity, b. filling two open mould cavities one on each forming element with a frozen aerated product having an overrun of between 30% and 130%, c. then allowing each product to expand outside its open cavity, d. then moving the two open mould cavities opposite one another so that the expanded frozen aerated product in each cavity is pressed against the expanded frozen aerated product in the other cavity, expansion of the frozen aerated product in said filled cavities being uninhibited after the filling devices to where the expanded frozen aerated product in each cavity is pressed against the expanded frozen aerated product in the other cavity.
