摘要:
A mould assembly for moulding ice sculpture having (i) complementary mould members (1, 2) of low thermal conductivity material, the complementary mould members being releasably mated together via complementary peripheral flanges (3, 4) having fixing means (8, 9, 10, 11, 12, 13, 14) therethrough, defining an open topped mould cavity; (ii) a water impervious flexible mould liner (18) conforming to the interior of the cavity and comprising a split region (19) around at least part of its periphery, having mating portions, each of the mating portions having extended (20, 21) lips adapted to be sealingly clamped together between adjacent mould members; (iii) a thermally insulating cover adapted to close the open top of the mould cavity, wherein the improvement lies in the provision of; (a) perforations (15) through the mould members at regions corresponding to protuberant parts of the ice sculpture to increase the rate of freezing of the protuberant parts and (b) providing thermal insulation (16) to the mould assembly at regions corresponding to narrow parts of the ice sculpture to decrease the rate of freezing of the narrow parts.
摘要:
The cooling system ( 10', 10", 10 III ) according to the invention, for a machine for processing a mixture comprises A) a central body ( 1', 1", 1 III ); B) at least three Peltier cells ( 2 ) each of which resting on said external flanks of the central body; C) one or more heat sinks ( 3 ); D) an assembling system ( 5' ) in turn comprising a belt element ( 51 ) and a tensioner ( 55 ). The tensioner ( 55 ) tensions the belt element ( 51 ) by tightening the three Peltier cells ( 2 ) against the external flanks of the central body ( 1', 1", 1 III ) and fixing the at least three Peltier cells ( 2 ) to such flanks. The invention also relates to a machine for producing ice creams provided with such cooling system.
