Abstract
Abstract A method for preparing a shaped ice confection product wherein a mixture of ice particles and a liquid, which mixture is pumpable under pressure but maintains its shape if unsupported, is introduced under pressure into a mould which is closed apart from venting openings. An apparatus for manufacturing shaped ice confection products comprising means for manufacturing an ice confection mixture comprising ice cristals and a liquid phase, a chamber (1) with pressurizing means (2) and a devisible mould (7) having heating means (15) and being closed, apart from venting openings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
In a method of preparing a shaped ice confection product comprising introducing a deformable partly frozen ice mixture composition into a cavity of a mold to form a shaped ice confection product, demolding the shaped ice confection product in a solid state and thereafter cooling the shaped ice confection product to harden it, the improvement comprising the step of introducing the partly frozen ice mixture composition into the cavity while under pressure and while it comprises separate ice crystals and a continuous liquid phase in relative amounts sufficient to maintain the shape of the ice mixture composition if unsupported, said mold being closed except for venting openings.
Claim 2
Dependent Claim
107 words
In a method of preparing a shaped ice confection product comprising introducing a deformable partly frozen ice mixture composition into a cavity of a mold to form a shaped ice confection product, demolding the shaped ice confection product in a solid state and thereafter cooling the shaped ice confection product to harden it, the improvement comprising the step of introducing the partly frozen ice mixture composition into the cavity while under pressure and while it comprises separate ice crystals and a continuous liquid phase in relative amounts sufficient to maintain the shape of the ice mixture composition if unsupported, said mold being closed except for venting openings.
Claim 3
Dependent Claim
21 words
Method according to claim 1 further comprising releasing the pressure from the mold and removing the shaped ice confection product therefrom.
Claim 4
Dependent Claim
27 words
Method according to claim 1 in which the partly frozen ice mixture composition is a water-ice mixture containing from 45 to 75% by weight of ice crystals.
Claim 5
Dependent Claim
23 words
Method according to claim 3 in which the partly frozen ice mixture composition contains from 50 to 60% by weight of ice crystals.
Claim 6
Dependent Claim
32 words
Method according to claim 1 in which the partly frozen ice mixture composition contains from 3 to 18% by weight of fat and from 30 to 45% by weight of ice crystals.
Claim 7
Dependent Claim
13 words
Method according to claim 1 in which the mold has a bulbous cavity.
Claim 8
Dependent Claim
34 words
Method according to claim 1 further comprising heating the mold to a temperature higher than that of the ice mixture composition during the demolding step to facilitate removal of the shaped ice confection product.
Claim 9
Dependent Claim
22 words
Method according to claim 1 wherein the mold has sintered microporous cavity walls to facilitate removal of the shaped ice confection product.
Claim 10
Dependent Claim
52 words
Method according to claim 1 further comprising partially inserting at least one ice confection support chosen from the group consisting of sticks and string into the cavity of the mold prior to introducing the ice mixture composition, such that the shaped ice confection product will have at least one support inserted therein.
Claim 11
Dependent Claim
34 words
Method according to claim 9 wherein the support is inserted into the mold cavity in such a way to allow for both extremities of the support to extend from either side of the cavity.
Claim 12
Dependent Claim
21 words
Method according to claim 9 wherein a plurality of sticks is inserted into the cavity of the mold at different positions.
