Abstract

Chocolate sweets (1) with a marbled effect are formed using a nozzle having an inner nozzle part (2) for a first tempered chocolate (10) and an outer nozzle part (3) for a second tempered chocolate (11). The inner nozzle part (2) is spaced radially inwardly of the outer (3). Bridging elements comprising wires (6,7) extend across the nozzle outlet (5) in a cruciform shape to interrupt the outlet and divide the flow path. The injection of dark chocolate (10) through the inner nozzle part (2) and the injection of the white chocolate (11) into a gap (12) between the inner and outer nozzle parts (2,3) coupled with the bridging wire elements at the nozzle outlet results in the simultaneous deposition of white and dark chocolate (10,11) to produce a marbled effect. The amount of white to dark chocolate dispensed can be varied by setting the injection pressures. The weight ratio of the white to dark chocolate injected into a chocolate-forming recess (20) of a mould (25) may be from 1:10 to 1:15 to produce a quality marbling effect. <Figure 6>

Description

The invention relates to a method for manufacturing chocolate sweets of the type having a marbled effect formed by patterns of differently coloured chocolate such as a dark chocolate with a white chocolate marbled effect or vice-versa.

Chocolates of this type are known. Generally the marbling effect is produced by first forming a sweet for chocolate of one colour and then applying a different coloured chocolate over the first chocolate. A stream of air is typically blown onto the second chocolate to produce the marbling effect. However, this is time consuming and inefficient. In addition, the marbling effect is produced generally only on the surface of the chocolate.

There is therefore a need for a process for producing such marbled effect chocolates more efficiently.

Statements of Invention According to the invention there is provided a method for manufacturing chocolate sweets having a marbled effect formed by inclusion of surface patterns of differently coloured chocolate comprising the steps of:providing a one shot chocolate forming machine having inlet hoppers, a plurality of outlet nozzles, and a delivery pump for delivery of material from the hoppers into recesses of a chocolate sweet-forming mould, each nozzle having an outer nozzle part and a concentric inner nozzle part, the inner nozzle part being spaced radially inwardly of the outer nozzle part; 1ST CL -7 ,. ft £3 Ψο ifc ¢030974 - 2 - . tempering a first chocolate; delivering the tempered first chocolate to a first inlet hopper of the one shot chocolate forming machine; tempering a second chocolate; delivering the tempered second chocolate to a second inlet hopper of the one shot chocolate forming machine; injecting the first tempered chocolate into the space between the inner and outer nozzles; injecting the second tempered chocolate into the inner nozzle; and 15 interrupting the flow of chocolate at the outlet of the nozzle to produce a marbling effect on injection into the mould recess.

In one embodiment the flow of chocolate at the outlet of the nozzle is interrupted by 20 dividing the flow path. The flow path is preferably divided by at least one bridging element extending across the nozzle outlet. There are preferably at least two intersecting bridging elements. Ideally there are two bridging elements which are preferably arranged in a cruciform shape. The or each bridging element may be of wire.

In one embodiment the weight ratio of the first and second tempered chocolates injected into a chocolate-forming recess is from 1:7 to 1:20, preferably from 1:10 to 1:15.

In one embodiment the first tempered chocolate is a white chocolate and the second chocolate is a dark chocolate. ¢03067 4 - 3 The invention also provides marbled chocolate sweets whenever manufactured by a method of the invention.

In another aspect the invention provides a nozzle for forming marbled chocolate sweets comprising an inner nozzle part for a first tempered chocolate and on outer nozzle part for a second tempered chocolate, the inner nozzle part being spaced radially inwardly of the outer nozzle part, and at least one bridging element extending across the nozzle outlet. Preferably there are at least two intersecting bridging elements, most preferably there are two bridging elements which are preferably arranged in a cruciform shape.

The or each bridging element may be of wire.

Detailed Description Referring to the drawings there is illustrated an apparatus and a method for forming chocolate sweets 1 with a marbled effect. The apparatus comprises a nozzle having an inner nozzle part 2 for a first tempered chocolate 10 and an outer nozzle part 3 for a second tempered chocolate 11. In this case the first chocolate 10 is of dark colour and «030874 - 5 the second 11 is white. The inner nozzle part 2 is spaced radially inwardly of the outer nozzle part 3. Bridging elements extend across the nozzle outlet 5 to interrupt the outlet and divide the flow path. In this case the bridging elements comprise two wires 6, 7 which are arranged in a cruciform shape. The injection of dark chocolate 10 through the inner nozzle part 2 and the injection of the white chocolate 11 into a gap 12 between the inner and outer nozzle parts 2, 3 coupled with the bridging wire elements at the nozzle outlet results in the simultaneous deposition of white and dark chocolate 10,11 to produce a marbled effect as illustrated particularly in Figs. 2 and 3. The amount of white to dark chocolate dispensed can be varied by setting the injection pressures. The weight ratio of the white to dark chocolate injected into a chocolateforming recess 20 of a mould 25 may be from 1:7 to 1:20 and preferably 1:10 to 1:15 to produce a quality marbling effect.

The invention provides a method for manufacturing chocolate sweets having a marbled effect formed by inclusion of surface patterns of differently coloured chocolate. The method comprises providing a one shot chocolate forming machine having a pair of inlet hoppers, a plurality of outlet nozzles 23, and a delivery pump for delivery of material from the hoppers into recesses 25 of a chocolate sweet-forming mould 20. Each nozzle having an outer nozzle part 3 and a concentric inner nozzle part 2, the inner nozzle part 2 being spaced radially inwardly of the outer nozzle part 3.

A first chocolate is tempered and delivered to a first inlet hopper of the one shot chocolate forming machine. A second chocolate is tempered and delivered to a second inlet hopper of the one shot chocolate forming machine.

The first tempered chocolate is injected into the space between the inner and outer nozzles 2, 3 and the second tempered chocolate is injected into the inner nozzle 2. The flow of chocolate at the outlet of the nozzle is interrupted to produce a marbling effect on injection into the mould recess 25. «03067 4 - 6 The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
