Patent ID: 8495892

Claim:
Process for the manufacturing of frozen aerated products comprising; (a) providing two forming elements, which are a pair of rollers with parallel axis, (b) providing a multiplicity of cavities on a surface of each roller, (c) providing a filler for filling said cavities with a frozen aerated material at a temperature higher than the temperature of the forming elements, (d) filling two cavities, one on each forming element, with a frozen aerated material having an overrun of between 10% and 130%, (e) allowing the frozen aerated material to expand outside of the cavities, (f) counter-rotating the rollers so that respective cavities in the two forming elements lie opposite one another and the frozen aerated material in a cavity of a first roller is pressed against the frozen aerated material in an opposite cavity of a second roller, (g) wherein each cavity of the respective cavities is lined to an edge of the roller on which the cavity is located through a groove which is adapted to face the groove of the respective cavities during step (f) a closer closes the groove when the filler fills the respective cavities, the closer comprising a lip on the side of the filler which blocks an end of the groove at the roller edge when the filler face a cavity and fills one of the respective cavities, and a stick is placed between the two filled respective cavities after step (d) and before step (f), within a space limited by the respective grooves of the respective cavities during step (f).
