Abstract
ABSTRACT
A method and an apparatus for producing articles made of moulded chocolate, employ an injection tool and a multipartite hollow mould enclosed on all sides except for the injection opening. Before the mould is closed, a retaining and transporting element is placed therein, this element being adapted to fit the lower mould in the areas where it comes into contact with the chocolate compound. Liquid chocolate is then injected through an injection nozzle at a high pressure into the cavity thus formed. The mould is cooled during and after the injection operation. Thereafter, the mould is opened and the retaining and transporting element, with the moulded-chocolate article adhering thereto, is removed and passed on for final cooling. As compared with known methods, the invention substantially accelerates the production method, since cooling the mould produces a considerable reduction in the overall cooling time. In addition to this, the number of relatively expensive moulds required is reduced, since each mould may be opened shortly after the injection operation, the moulded article may be removed by means of the retaining and transporting element, and the mould is then ready for the next injection operation.

Description
llZ8~313 The invention relates to a method and apparatus for producing articles of moulded chocolate, in which a multipartite mould is closed on all sides, except for a filling aperture, to form a cavity corresponding to the moulded-chocolate article, whereupon heated chocolate is introduced into the said cavity under pressure until it is completely full, solidification of the chocolate compound being achieved by cooling.
It is known from German Patent 462 968 to unite two shell-like mould-parts to form a closed cavity, e~cept for a filling aperture, and to force chocolate, in the form of a semi-paste, into that cavity under pressure.
After the mould had been filled, the pressure is still maintained for a cer-tain length of time, in order to increase the density of the chocolate in the mould-cavity. The mould is then moved away from the filling station and, after a handle has been inserted into the chocolate compound through the fil-ling aperture, is passed through a cooling chamber. At the outlet from the cooling chamber, the mould is opened and the moulded article is taken out.
This method, however, has not been found satisfactory in practice.
For one thing the cycle is too slow, i.e. the number of filling operations per unit of time is too small as compared with competing methods, since, in the case of shell-like mould-parts, the applicable pressure is limited for me-chanical reasons, and the filling operation itself therefore takes too long.
Purthermore, for quantity production, a large number of expensive dies must be available since the moulded article cannot be taken from the mould until it has passed through the cooling chamber and each mould is therefore in use for a very considerable period of time.
The invention provides a method for producing articles of moulded chocolate, in which a multipartite mould is closed on all sides, except for a filling aperture, to form a cavity corresponding to the moulded-chocolate - article, whereupon heated chocolate is introduced into said cavity under pres-.
88~3 sure until it is completely full, solidification of the chocolate compound be-ing achieved by cooling, said method comprising:
a) placing in the mould before it is closed, a retaining and transport-ing element, said element being adapted to the shape of the moulded-chocolate article in the areas coming into contact with the chocolate compound;
b) injecting molten chocolate under pressure into the cavity;
c) precooling the mould, by means of a fluid, during and after the in-jection operation; and d) opening the mould and removing the retaining and transporting ele-ment, with the moulded-chocolate article adhering thereto, from the mould and passing it on for final cooling.
The invention also provides an apparatus for producing articles of moulded chocolate comprising: an injection tool; a multipartite mould co-operating therewith and adapted to be united to form a hollow mould; and a sub-sequent final cooling means, wherein:
a) said forming tool is solid and contains cooling ducts;
b) a retaining and transporting plate is adapted to be clamped between the two parts of the mould, said plate in conjunction the parts of the mould forming a mould cavity, and c) injection ducts in the mould parts which terminate, in the area of said cavity, in the form of a nozzle which is adapted to be closed off.
Above all, the procedure according to the invention allows the mould to be opened shortly after the injection process, since by then the chocolate compound has become adequately solidified, at least as far as the surface is concerned,as a result of the pre-cooling. Removal of the article from the mould, which follows immediately, is made possible by the retaining and transporting element in which the moulded-chocolate parts rest, and which compensates for the fact that, at this stage, the overall strength of the chocolate compound is 88~3 not yet adequate. The time required for final cooling is shortened, not only by the aforesaid preliminary cooling, but also by the fact that cooling air has immediate access to the surface of the moulded article, except in the area covered by the retaining and transporting element. The element may also be used for packing the moulded-chocolate articles.
The invention is explained hereinafter in greater detail, by way of example only, in conjunction with the a~tached drawing wherein:
Figure 1 is a cross section of a two-piece closing mould, having an inserted retaining and transporting plate, for the production of cup-like or 1~ trough-like hollow chocolate articles;
Figure 2 is a cross section of a mould, having a grid-like retaining and transporting plate, for the production of solid chocolate articles;
Figure 3 is a cross section of the injection nozzle at the end of the injection duct.
The mould according to Figure 1 consists essentially of an upper part 1 and a lower part 2. The latter has cup- or trough-like depressions 3 and is fitted with a retaining and transporting plate 4. The upper part l has projections 5 which fit into the depressions 3 in such a manner that, when the mould is closed, and plate 4 is held between mould-parts 1 and 2, cup- or 2a trough-like cavities 6 are produced, into which the molten chocolate compound is injected. To this end, injection-ducts 7, 8 are arranged in upper part 1.
At the lower ends of projections 5 in the cavities 6, these ducts terminate in fine nozzles 9 (Figure 3) which can be closed off. The nozzles are fitted with heating cartridges 1~ (Figure 3) embedded in a shut-off needle 13. Nozzles 9 and ducts 8 are also lined with a layer of insulating material 14.
Parts 1 and 2 of the mould have ducts 11 through which a liquid coolant, for example ammonia, may be passed. The upper part 1 is also equipped with rod-like stripper or ejectors 12 which are axially movable and have their ~L~Z88~3 lowers ends adjacent cavities 6. All surfaces in cavities 6 are coated with a release agent, e.g. polytetrafluoroethylene.
After the retaining and transporting plate 4 has been inserted, and mould 1, 2 has been closed, molten chocolate is injected at high pressure (up to 30 bars), by an injection-tool (indicated by head 18), into the duct 7, whence it is distributed to the ducts 8. The compound enters the cavities 6 through the nozzles 9 and completely fills the cavities. The parting surfaces of the mould are sufficiently rough to allow the escape of air expelled from the mould cavities. During and after this operation, the mould is cooled by means of a liquid passing through ducts 11, the lower part 2 being held at about 20C and upper part 1 to about -5C.
Ater the surface of the moulded article adjacent upper part 1 has solidified, the mould 1, 2 is opened, the ejectors 12 remaining initially in contact with the moulded articles. As soon as the ejectors have been with-drawn, the plate 4 with the moulded articles lying therein may be removed and taken away for final cooling. Prior to the next injection cycle, the nozzles 9, and all injec~ion ducts 7, 8, if necessary, are heated, in order to liquefy the solidified compound therein. Plate 4 may be stamped out of dimensionally stable metal oil or plastic and may remain with the moulded articles as a packing material.
Figure 2 shows an apparatus similar to that in Figure 1, but which is used to produce solid moulded-chocolate articles. Elements performing the same functions as those in Figure 1 bear the same reference numerals.
In this embodiment, the retaining and transporting element 4 is per-forated or is in the form of a grid, webs 15 thereof being clamped between parts 1 and 2 of the mould. The edges 16 defining the holes are flush with the de-pressions 3 and thus complete them. Moreover, these edges are conical in relation to parting surface 17 of the mould, so that the moulded-chocolate :
`
~LZ88~3 parts produced in the cavities 6 cannot fall out of element 4 upon being re-moved from the mould, or during further transportation.
