Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an apparatus for producing frozen confectionery containing solid fruits.

[Conventional technology]

BACKGROUND ART In recent years, consumer tastes have diversified, competition in all industries has become increasingly intense, and a variety of products have become popular in the market. The food industry is no exception, and there are many products on the market that not only vary in color and shape, but also consist of combinations (compounds) of different materials. For example, whether Japanese or Western sweets, chestnuts, nuts, melons, strawberries, and other fruits (hereinafter referred to as fruits) are often enclosed in a castella-like, jelly-like, chiyocolate-like, or agar-like base material. be.

When embedding fruits, etc. inside a base material in this way, if the base material is transparent or translucent, the presence of the fruits, etc. can be easily confirmed from the outside, but this is not possible with the base material of castella. Since then, a method has been adopted in which the portion where the fruits are present is cut and the cut surface is exposed on the surface of the base material.
This is true not only for hot and frozen desserts, but also for frozen desserts (ice cream, ice candy, sherbet, etc.), and it is by no means easy to expose a cut of any size in any position. isn't it. Therefore, when producing frozen confectionery, a method has been adopted in which fruits are inserted into the inner surface of an ice tube filled with ice cream so that the cut surface is in contact with the inner surface of the ice tube. It was almost impossible to securely fix it in position.

Therefore, the applicant of this invention filed the patent application No. 62-25166.
In this issue, fruits cut into appropriate sizes are placed at any position on the inner surface of a metal plate that can be in close contact with at least one surface of the inner surface of an ice tube (generally called a mold, ice mold, etc.). Place the cut surfaces so that they are in contact with each other and freeze together with the metal plate.The metal plate with the fruits frozen and fixed thereon is inserted so as to be in contact with the inner surface of the ice tube, and the mixture is poured into the ice tube.The frozen product is then frozen in accordance with a conventional method and solidified. The present invention discloses a method for manufacturing frozen confectionery containing solid fruits, characterized in that the metal plate is removed from the surface of the frozen confectionery to expose a cut surface of the fruit on the surface. With this method, it is possible to clearly and clearly expose the cut surface of the fruit embedded in the frozen confection at the desired position of the frozen confection, and it is relatively easy to operate and can be used for mass production. It has become possible to obtain effects that were not seen with conventional technology. However, even though the method of using such a metal plate is easy to operate, it cannot afford to overlook the trouble of installing and removing it in the ice tube, and a method with better workability is desired.

[Problem that the invention seeks to solve]

As described above, the problem with the conventional technology is that no method or device has yet been found that is simple and has excellent workability for exposing the surface of embedded fruits, etc., at any desired location on the surface of frozen confectionery. It was hot.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a part that inserts solid fruits into the inner wall of the ice tube, makes them stick to the inner wall of the ice tube, freezes the fruit on the inner wall of the ice tube, a part that fills the ice tube with raw material mix, and a part that fills the ice tube with the frozen confectionery. This device adopts means for producing frozen confectionery containing solid fruits using an endless conveyance method, which consists of a portion for extracting solid fruits from the frozen confectionery.

[Effect]

This invention makes it possible to make the solid fruits adhere to any arbitrary position on the inner wall of the ice tube at the part where the solid fruits to be frozen are inserted and brought into close contact with the inner wall of the ice tube built into the endless conveyance type ice candy manufacturing device. This shows the effect of improving workability and facilitating mass production.

〔Example〕

FIG. 1 schematically shows one embodiment of the present invention. In this figure, the ice tube 1 may be one or a plurality of ice tubes connected in a row, but the latter is of course preferable for mass production. The ice tubes 1 connected to the endless conveyance system 2, ie, the endless conveyor system, are conveyed in the direction shown by the arrow. Therefore, while the ice tube 1 goes around the endless conveyance system, it is inverted, turned sideways, suspended, and turned sideways, and then returns to the inverted state again. Normally, the ice tube 1 in a suspended state is placed in a filling hopper 4 in a freezing tank 3 filled with a refrigerant such as brine.
The ice tube 1 is transferred while freezing the raw material mixture received from the freezing tank 3. Although not shown in the drawings, once the mixture has been frozen, the ice tube 1 comes out of the freezing tank 3 and is placed on its side. Near this point, the outer surface of the ice tube 1 is momentarily warmed with water, etc., and after the frozen confectionery inside is removed and emptied,
Return to the original inverted position. Here, in this invention, there is a part where solid fruits are inserted into and brought into close contact with the inner wall surface of the ice tube 1 before the installation location of the filling hopper 4 of the ordinary endless conveyance system as described above. . Therefore, in the example of FIG. 1, the ice tube 1 that has transitioned from an inverted state to a sideways state is further tilted and becomes a suspended state in area A, or the ice tube 1 that has once been in a suspended state is guided to the freezing tank 3. Inserting solid fruits into the inner wall surface of the ice tube 1 into at least one of the areas B up to just below the filling hopper 4,
It is desirable to provide a device for close contact.

Now, a specific example of a device for inserting solid fruits into the inner wall surface of the ice tube 1 is shown in FIG.
The result will be as shown in Fig. 3 or 4.

First, the example shown in FIG. 2 is composed of a frame 6 to which inserting hands 5 corresponding to a plurality of ice tubes 1 are fixed, and an air cylinder 7 for moving the frame up and down.For example, the example shown in FIG. All you have to do is put the fruit pieces 9 into the ice tube 1 lying on its side from the workbench 8, and when the ice tube 1 is slightly inclined, operate the insertion hand 5 with the air cylinder 7 to push it into the desired depth. . It is also possible to cool the ice tube 1 from the outside by spraying a refrigerant such as liquid nitrogen from a nozzle 10 to prevent the fruit pieces 9 from slipping off, thereby freezing the fruit pieces 9 on the inner wall surface.

Next, in the example shown in FIG. 3, a blowing hole 11 is provided around the tip of the inserting hand 5, and the fruit supplied from the fixed tray 12 is attached to the periphery of the blowing hole 11, and then the inserting hand 5 is inserted into an ice pipe. 1 to a desired depth, and at that position pressurized air from the blow-off hole 11 presses the fruit against the inner wall. If such a device is installed in area B of FIG. 1, the fruit pressed against the inner wall of the ice tube 1, which has been immersed in the freezing tank 3 and cooled in advance, will immediately freeze and become fixed.

Furthermore, in the example shown in FIG. 4, the insertion hand 5 has a suction cup 13.
It has been established. The insertion arm 5 in FIG. 2 has a simple curved shape, and in FIG. Since it is tubular, there are few restrictions on the shape of the ice tube 1. The number of suction cups 13 is not limited to two at the top and two at the bottom, but it is very preferable if they can be connected to the compressed air hose 14 or the vacuum hose 15 to arbitrarily adjust the adsorption and desorption of fruit.

〔effect〕

According to the manufacturing apparatus of the present invention, it is possible to easily expose the surface of the embedded fruit or the like at any location on the surface of the frozen confectionery with a simple operation. Therefore, since it is easy to mass-produce such frozen confections containing solid fruits, the significance of this invention is extremely great.
