(54) Method of decorating ice = sticks and apparatus for troughing in the practice of the method.

The invention relates to a method for decorating ice sticks.

For the decoration of ice sticks, it is known to mix the cream to be frozen to make the ice stick, brightening additives, e.g. coarsely divided, differently colored fruits.

Furthermore, it is known to obtain a decorative mark by filling the freezer compartments.

pockets in which the ice pegs are manufactured, several times with different CM colored liquids, and furthermore, the ice pegs can be provided with several coatings, which only partially overlap, so as to produce a ring'd or belt effect where the various rings or belts have different color.

Actual staining of the ice sticks has so far only been possible in the said case, where the freezer pockets are filled several times with different colored liquids, and the decorative effect which can be obtained is very limited, since only a belt effect can be obtained. . The decoration, which is obtained by supplying the ice cream sticks with several coats, disappears as the ice cream is consumed, and the mixing of colored fruits can only give the ice cream stick a very random decoration which further changes as the consumer consumes the ice cream stick.

It is the object of the present invention to provide a method by which ice sticks can be provided with patterns extending into the ice sticks so that the pattern is retained even after the consumer has begun to consume the ice stick, and this is achieved by the invention by a material which contrasts with the material of the ice pegs by means of high pressure nozzles and in the form of a beam forming a pattern is pushed into the ice pegs. Hereby, a pattern is obtained which, instead of being superficial, as would be the case if applied by ordinary low-pressure spraying technique, is profound, so that the pattern retains its character even after the consumer has begun to lick the stick, and furthermore, an appealing and "clean" pattern is obtained without any gap between the material of the ice pegs and the material constituting the pattern, since it has been shown in experiments that the inserted pattern-giving material immediately after the insertion is solidified due to the large heat conduction that occurs. from the injected material to the ice stick material which has a low temperature in advance. This approximately instantaneous freezing of the injected material simultaneously causes the injected material to not drift out of the holes formed by the jets and damage the outside of the ice pegs. The process of the invention is at the same time easy to carry out and hygienic, in contrast to the conceivable case where such a pattern forming material would be introduced by injection, i.e. by inserting needles into the ice stick material and withdrawing the needles while simultaneously dispensing pattern forming material into those of the needles or the needles created holes. Thus, a new and distinctive as well as appealing decoration is obtained for ice sticks, which is based on the recognition of the high penetration effect of high-pressure rays in the frozen material, which consists of the ice sticks.

This patterning by means of high-pressure jets can be done unilaterally by directing the high-pressure jets to one side of the ice pegs while simultaneously applying a stop at the side facing away from the jets, but according to the present invention it is preferred that the patterning is done by two high-pressure jets simultaneously. is pushed into the ice stick in mutually opposite directions to provide the ice stick with patterns on both sides and to obtain a symmetrical load of the ice stick during patterning. Such a two-sided high-pressure jet insert is also advantageous in that such a strong one-sided jet insertion that the jets pass through the ice stick may cause distortion of the pattern at the side of the ice stick that faces away from the side in which the insertion takes place.

A rational method is achieved according to the invention if the jet insertion is made immediately after picking up the ice stick from an ice stick freezer.

The invention also relates to an apparatus for use in the method, which apparatus according to the invention is characterized by high-pressure nozzle means which are arranged in a pattern and which are connected by means of conduction means to a source for delivery of a material under high pressure, which material contrasts with the material of which the ice pegs consist, as well as transport means designed for placing the ice pegs in the path of movement of the high-pressure jets delivered by the nozzle organ and for removing the ice pegs from this web.

In order to achieve the two-sided pattern mentioned above, the apparatus according to the invention may have two sets of facing nozzles and the transport means may be arranged to place the ice pins between the two sets of nozzles.

For use in using the apparatus of the invention in conjunction with an ice-stick freezer, the conveying means of the invention may be constituted by a pick-up and dispatch mechanism for a rotating ice-stick freezer, the pick-up and delivery mechanism having vertically movable support members for series ice pods, arranged in a vertical and horizontal direction. arranged in two rows parallel to one row of ice pegs carried by the recording and depositing mechanism in one of the transport positions of the recording and depositing mechanism, in which the respective supporting means of the recording and depositing mechanism are movable in a vertical direction.

The invention will now be explained in more detail with reference to the drawing, in which fig. 1 is a diagrammatic side view of a rotary ice-stick freezer machine and an embodiment of the apparatus according to the invention; 2, 3 and 4, the beam insertion apparatus of the embodiment of FIG. 1, together with a series of ice sticks, seen from the end, shown in three working positions to illustrate an embodiment of the method according to the invention, and FIG. 5 is a side view of an ice stick, provided with a pattern made using the beam insertion apparatus.

In the drawing, 1 denotes a freezer table, of which only one portion is shown, which can be intermittently rotated about a vertical axis 2. In the freezer table there are recessed freezer pockets 3 with upwardly slightly extending cross-sectional area to allow the uptake of frozen ice pegs there. The freezer pockets 3 are arranged in concentric rows around the axis 2, in the present case seven such concentric rows, and the freezer pockets 3 are further arranged in radially radiating rows from the axis 2. The freezer table 1 includes a fixed lower part 5, which is known per se and is therefore not shown in more detail for rinsing the freezer pockets 3 with refrigerant and, along a part of the circumference, with a thawing medium for loosening the pockets 3 frozen ice pegs.

Included in the ice-stick freezer shown is a pick-up and dispensing mechanism, which is generally designated by 7. Its upper part 8, in the embodiment shown in the drawing, carries support means in the form of a radially extending arm 9 which carries a series of clamps 10, namely one for each of the concentric rows of freezer pockets 3, which clamps 10 serve for engaging with pins 11 which are frozen to this during freezing of the ice stick material in pockets 3.

For the ice stick freezer in FIG. 1, there is also a dispensing station, which as a whole is indicated by 12. This consists of a support 13 over which a conveyor belt 14 is slidably mounted.

For the ice stick freezer in FIG. 1, there are high pressure nozzle means 15 which are connected by means of high pressure conducting conduit 16 and above a high pressure pump 17 to a reservoir 18 intended for receiving a material which contrasts with the material from which the ice pins 4 are made. The material in reservoir 18 can e.g. have a different color or texture other than the ice stick material.

There are two sets of high pressure nozzle means 15 and these are arranged parallel to each other and parallel to the arm 9, namely in a position thereof, where it holds a series of ice pins 4 above the nozzle means 15.

The FIG. 1, the ice stick freezer operates as follows:

The freezer pockets 3 are filled by means of a feed device not shown sequentially, namely one radial row of freezer pockets at a time, while the table 1 is stationary. After filling a row of pockets, the table 1 is moved one step in the circumferential direction, which step corresponds to the angle of the stand between two consecutive radial rows of freezer pockets, and then the next row is filled. When the material placed in the freezer pockets achieves such consistency that sticks can be placed therein and retain their position, such sticks are placed by means of a sticksetter of a kind not known per se, and the intermittent movement continues until the ice stick material is frozen. , at least to such an extent that the sticks are stuck and the ice sticks can be picked up by the recorder. The uptake takes place after a brief loosening of the frozen ice pegs in relation to the freezer pockets has taken place and the upper part 8 with the arm 9 standing in the position shown in FIG. 1 in fully drawn lines and lying in the plane of the drawing are lowered by open clamps 10. When the clamps 10 have reached the height of the pins 11, the clamps 10 are closed and the arm 9 is moved upwards, in fig. 1, the arm 9 is shown on the way up, it will be seen that the ice sticks 4 have left the bottoms of the freezer pockets 3.

When the arm 9 is raised so high that the undersides of the ice sticks 4 are clear from the upper side of the freezer table 1, the upper part 8 with the arm 9 is rotated a quarter turn so that the arm 9 is perpendicular to the drawing plane in fig. 1 and protrudes from this. This position is indicated in FIG. 1 at 91. In this position, the row of ice pegs 4 carried by the arm 9 resides over the two rows of high-pressure nozzle means 15, and then the upper part and the supporting means, shown symbolically in FIG. 2,3 and 4 by the reference numerals 9 and 11, namely that the ice pegs 4 are moved to a position; 3, where they are located between the high pressure nozzle means 15. In this position, a valve mechanism for flowing high pressure material to the nozzle means 15 is opened by means of a valve mechanism (not shown), by which beams of beams which are indicated in the drawing by lines 20.20. The pressure used is very large, namely between 50 and 500 ato. This, combined with the design of the nozzle means 15 * as high pressure nozzles known per se, gives the jets great impact on the ice pegs 4 arranged between the nozzles. namely, that the projected rays penetrate deep into the ice stick on both sides thereof, as indicated by short lines 22 in FIG. 4. After this spraying operation is completed, namely by closing the valve means not shown, the arm 9 is lifted to the position shown in FIG. 4 and the patterned ice pegs are now pivoted by turning the upper part 8 to a position diametrically opposite to the take-up position of FIG. 1, namely to a position shown in dotted line in FIG. 1, above the deposition station 12, where deposition of the patterned ice sticks takes place in a manner known per se and therefore not explained in more detail.

In experiments, it has been found that by appropriate selection of the pressure used in the pattern, the appropriate choice of the high pressure nozzle means and the viscosity of the pattern medium used, and the time during which the spraying takes place, which parameters can be determined empirically, clean and deeply penetrating patterns emerge. , without the deposited material running down the sides of the ice pegs. This is because, by virtue of their prior freezing, the ice sticks have great heat-absorbing capacity, namely, so that heat is supplied to the surrounding ice stick material approximately instantaneously, so that the deposited material solidifies very rapidly, and thus, after the spraying has ceased, have the opportunity to drive out of the holes formed by the rays.

In the embodiment shown in the drawing, there is shown a recording and depositing mechanism 7 of very simple construction, namely with only one support arm 9. It will be understood, however, that the present invention is not limited to recording and depositing mechanisms of this kind, but also can be used in connection with pick-up and delivery mechanisms, in which supporting means in the form of rods with clamps or similar gripping means are moved parallel to each other during passage from the freezer table 1 to the dispensing station, and between these two places, up and down between the high-pressure nozzle means 15.

Furthermore, two sets of high pressure nozzle members are shown in the drawing. However, if one wishes to provide only the ice sticks with patterning on one side, it will be appreciated that one set of high pressure nozzle means 15 can be used, in that case the other set is replaced by a suitable restraint which can provide a basis for the series of ice sticks 4 while pushing high-pressure jets from the side facing away from the restraint.

In FIG. 5 there is shown one side of an ice stick 4, provided with a decoration provided by the apparatus according to the invention in the form of an A, whose dash, dash and dash all consist of two rows of very small spots. However, these are not stains, but rather strings of material which contrast with the other material of the ice stick and which extend deep into the ice stick and which are inserted into the ice stick by a set of very fine high pressure nozzles. However, it will be appreciated that many other types of patterns can be used, e.g. forms symbols, letters, numbers or similar characteristics. Furthermore, the pattern on the two sides of the ice stick, if both are decorated, need not be the same, but may e.g. be mutually flipped.
