Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for decorating ice candy and an apparatus for carrying out this method.

In order to decorate ice cream cakes, it is known to add strongly colored ingredients, such as crushed fruits of various colors, to the cream from which ice cream cakes are made. It is also possible to achieve a decorative effect by separately filling liquids of different colors into the freezer pocket in which the ice cream candy is made, and also to create different coatings on the ice cream candy that partially overlap each other. It is also known that they can sometimes produce annular areas of different colors.

Traditionally, colored ice cream candy was only possible if the freezer pockets were filled one after the other with liquids of different colors, and the decorative effect produced in this way was achieved by filling several strips of different colors. It is quite limited by the fact that it can only be decorated. Decorations created by creating multiple coatings on an ice cream candy disappear when the consumer licks them, and haphazard decorations created by adding colored fruit to the cream disappear when the consumer licks them. It changes when you lick it.

It is an object of the present invention to provide a method for making an ice cream candy with a pattern extending into the ice cream candy so that the pattern is maintained even after the consumer starts licking it; According to the invention, a material forming a contrast with the material of the ice candy is injected into the ice candy by high pressure nozzle means and in the form of a bundle of jets forming a pattern. It is achieved by doing so. By means of this method, a pattern is created that extends deep into the ice scanday, rather than being shallow as is done by conventional low-pressure fogging techniques. The feature is that the eye-catching and clear pattern is maintained even after the consumer starts licking the ice cream candy, and there is no gap between the material of the ice cream candy itself and the pattern forming material. It will be done. Experiments have shown that the pattern-forming material can freeze in the cold ice-candy material immediately after being injected into the ice-candy material due to a high degree of heat transfer from the pattern-forming material. Proven. This almost instantaneous freezing of the patterning material also has the effect that the patterning material does not flow out of the holes formed by the jet and therefore does not deform the outer surface of the ice candy. are doing. Moreover, the method according to the invention is easy and hygienic to carry out, and if the patterning material is introduced into the ice candy by injection, i.e. by inserting a hollow needle into the ice candy and then If this is done by withdrawing the needle while feeding the patterning material into the hole formed by the needle,
It's not hygienic. Moreover, the new, distinctive and eye-catching decoration of the ice cream cake is based on the realization of a high-pressure jet with a high capacity for deep injection into the frozen material from which the ice cream cake is made.

Decoration by high pressure jet means can be carried out by directing the high pressure nozzle towards one side of the ice candy and supported by a support device on the other side of the ice candy, but according to the invention For example, two bundles of high-pressure jets may be simultaneously injected into the ice candy in opposite directions to create decorations on both sides of the ice candy and to apply symmetrical loads to both sides of the ice candy during pattern application. Therefore, it is preferable to carry out this method. Such double-sided injection of high pressure into the ice candy is also advantageous. This is because injection from one side causes the jet to penetrate deeply into the ice scanner, resulting in deformation of the pattern on the side of the ice scanner that is far from the side where the pattern forming material is injected. .

According to the invention, a rational method is carried out by jet injection immediately after the ice candy is removed from the ice candy refrigerator.

The invention also relates to a device for carrying out the above method. The apparatus according to the invention comprises: a high pressure nozzle arrangement arranged to form a pattern; a conduit arrangement connected to a source for supplying a material at high pressure as opposed to the material making up the ice candy; The ice candy is configured to be placed in a movement path of a high-pressure jet discharged from the ice candy and includes a moving device for moving the ice candy from said path.

To create the pattern on both sides as shown above,
The device according to the invention consists of two sets of nozzle devices facing each other and a transfer device that can be arranged to place the ice candy between said two sets of nozzle devices.

In order to be able to use the device according to the invention in conjunction with an ice candy refrigerator,
The transfer device can, according to the invention, be constituted by a picking and unloading device of a rotary ice candy refrigerator, said picking and unloading device being arranged in rows and movable vertically and horizontally. an ice candy support device, by means of which the nozzle device can be moved vertically in one position of the pick-up and removal device, in a row fed by the pick-up and removal device; The ice candy is arranged in two rows extending parallel to each other.

Other advantageous features of the invention will become clearer in the following description of a preferred embodiment of the decorative device according to the invention with reference to the drawings.

The ice candy refrigerator shown in Figure 1 is
It consists of a freezing table 1, only a part of which is shown, which can be rotated in steps around a vertical axis 2. On the frozen table, freeze pocket 3
are arranged so as to have a cross section that slightly expands in the upward direction, so that the ice candy 4 frozen in the freezer pocket can be removed from the freezer pocket. The freezer pockets 3 are arranged along concentric circles around the axis 2, and in this embodiment:
Arranged along seven concentric circles, the freezer pockets are further arranged in rows extending radially with respect to the axis 2. The refrigerator also comprises a base 5, along a part of which a device for supplying a freezing medium to the outer surface of the freezer pocket 3;
It includes a device for supplying a thawing medium to the outer surface of the freezer pocket 3 along the other portion of the platform to warm and loosen the ice candy frozen within the freezer pocket and for removing the ice candy. These devices are not shown as they are known per se.

The ice candy refrigerator shown also comprises a pick-up and removal device 7, consisting of a superstructure 8 which can be raised and lowered and which can be rotated about a vertical axis; Not shown. According to this embodiment, the superstructure 8 carries a support device in the form of radially extending arms 9 to which are attached a row of clamps 10, i.e. one for each concentric row of freezer pockets 3. Two clamps are installed. The clamp 10 serves to engage the stake 11 to be frozen on the ice candy during freezing of the ice candy material in the freezer pocket 3.

Furthermore, the ice-candy refrigerator shown in FIG. 1 includes a removal station 12 having a support 13 over which a conveyor band 14 extends.

The ice candy refrigerator shown in FIG. 1 of the embodiment of the device according to the invention also comprises a high-pressure nozzle arrangement 15, which is connected to a storage tank 18 via a high-pressure introduction conduit arrangement 16 and a high-pressure pump 17. ,
This reservoir contains materials that are in contrast to those from which the ice cream candy is made. The material in reservoir 18 may have a different color or a different consistency than the ice candy material, for example.

These two sets of high-pressure nozzle devices 15 are arranged parallel to each other and parallel to the arm 9 above the nozzle device 15 at the position of the arm 9 that supports one row of ice candy 4.

The ice candy refrigerator shown in Figure 1 is
It works as follows.

The freezer pockets 3 are attached to the table 1 one row at a time, i.e. one radial row of freezer pockets at a time.
While the is stationary, it is filled with material by means of a filling device. Since the filling device itself is well known,
Not shown. After filling one row of freezer pockets, the Cheeble 1 is rotated by one step corresponding to the angle between two adjacent radial rows of freezer pockets, and then the next row of freezer pockets is filled. A stake insertion device places a take into the freezer pocket when the material in the freezer pocket is at a concentration that will allow the stake to be placed therein and maintain its position. This stake insertion device itself is well known and is therefore not shown. The stepwise movement is continued until the ice candy material is frozen, at least until the stake is fixed, after which the stake is gripped by the pick-up arm 9. The pick-up operation is
After the frozen ice cream candy has been warmed up a little and loosened from the freezer pocket, the removal is carried out by lowering the support structure 8 with the arm 9 placed in the position shown in solid lines in FIG. Arm 9
is placed on the plane of the drawing and the clamp 10 is in the open position. When the clamp 10 is lowered to the level of the stake 11, the clamp 10 is closed;
Arm 9 is then raised. In FIG. 1, the arm 9 is shown pointing upwards, and the ice candy 4 is shown away from the bottom of the freezer pocket 3.

When the arm 9 is raised to a height where the lower surface of the ice candy 4 separates from the upper surface of the freezing table 1, the support structure 8 with the arm 9
is rotated one quarter turn to a position where it extends perpendicularly to the plane of the drawing and projects outwardly from the plane of the drawing in FIG. This position is designated 9' in FIG. In this position, one row of ice candies 4 suspended on arm 9 extends above two rows of high-pressure nozzle devices 15, and then the support structure 8 together with arm 9, clamp 10 and ice candy 4, as shown in FIG. was lowered to the position of
Here, the ice candy uses high pressure nozzle device 1.
It is placed between 5. In FIGS. 2-4, the arms, clamps and stakes are shown schematically and designated 9,11. In the position of FIG. 3, valve arrangement 19 is opened to flow high pressure material from pump 17 to nozzle arrangement 15 to inject a jet bundle, as indicated by lines 20,20. The pressure used is quite high, i.e. 50
~500 atmospheres, combined with the fact that the nozzle arrangement 15 is configured as a high-pressure nozzle, results in a jet of high penetration capacity, such that the jet ejected from the nozzle arrangement is as indicated by the short line 22 in FIG. It was shot deep into both sides of Ice Candy 4. The structure of the high pressure nozzle itself is known. After the injection operation is completed, the valve device 19 is closed and the arm 9 is raised to the position shown in FIG. , or the dotted line position above the removal station 12, to which position the decorated ice candy is then released onto the conveyor band 14. Its operation is well known and is therefore not shown.

According to the experiments of the present invention, parameters that can be easily determined empirically, namely the pressure used during decoration;
By appropriate selection of the high-pressure nozzle equipment, the viscosity of the pattern material, and the time of injection, a sharp, deep pattern can be created on both sides of the ice candy, regardless of any apparent properties of the pattern material. It has been proven that it can be done.
This is because the ice cream candy has a high heat absorption ability due to being pre-frozen, and the heat from the material injected into the ice cream candy spreads almost instantaneously to the surrounding ice cream cakes. The material that is conducted and injected into the ice candy freezes rapidly,
Therefore, after the injection work is completed, the jet does not flow out of the hole formed by the jet.

In the drawing, a very simple embodiment is shown for a pick-up and removal device 7 with only one arm 9. However, the invention is not limited to such pick-up and unloading devices, but does not imply that a bar-shaped support device with a clamp or similar gripping device is used between these two positions during the movement from the freezing table to the unloading station. It can also be used in conjunction with pick-up and removal devices, which are moved parallel to each other and raised and lowered between high-pressure nozzle devices.

Additionally, two sets of high pressure nozzle devices are shown in the drawing. However, it will be appreciated that if only one patterned ice candy is required to be made, one set of high pressure nozzle devices 15 can be used. In such a case, the other set of high-pressure nozzle devices should be placed on the side of the ice scanner that is not injected with a jet by a suitable support that can support the ice scanner during injection of the high-pressure jet. will be replaced.

In Figure 5, one side of the ice cream candy 4 is shown having an A-shaped decoration applied by the device, and all of the upper, lower and horizontal lines of the A-shape are formed by two rows of small dots. Become. However, in reality, these points are injected into the ice candy by a set of very narrow, high-pressure nozzles and extend deep into the ice candy to form a contrasting material to the ice candy material. represents a continuous line.
However, there are many other patterns, such as symbols,
It will be understood that patterns such as letters and figures can be used. Furthermore, if both sides of the ice cream candy are decorated, the patterns on both sides need not be the same, one may be symmetrical to the other.
