Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing stretched rice cakes, and is particularly designed to automatically form stretched rice cakes with excellent square shape precision, and to obtain a large number of cut rice cakes with no loss and high commercial value from the stretched rice cakes. This has been improved so that it can be used.

Generally, stretched mochi is formed from a freshly pounded mochi block into a flat plate of a certain thickness, which is dried and solidified and then cut into a large number of rectangular cut mochis, which are then sold as products. It is customary. In order to manufacture stretched rice cakes, it does not matter when mass production is done using various machines such as extrusion screws and rolls, but when producing small to medium quantities by relatively small-scale companies, conventional push rods are used. The actual situation is that the mochi mass is shaped and dried manually by applying pressure to the mochi mass, stretching it, and placing it in a rectangular saucer-shaped molding container.

However, such a manufacturing method is inferior in work efficiency and not only results in high costs for the product (kirimochi), but also has the following serious defects in terms of commercial value.

That is, since freshly pounded rice cake lumps have restoring elasticity, it is difficult to form them into stretched rice cakes and reliably fit them all the way to the corners of a rectangular container. Even if it can be fitted once, it will be restored and deformed as if it were contracted afterwards, and a gap s will be created between the periphery of the rice cake mass a and the four corners of the molded container b, as shown in Fig. 5. I will do it. In other words, the periphery of the stretched mochi becomes rounded, and when the stretched mochi is cut into square-shaped mochi and divided into smaller pieces, the four corners become wasted. Or, the cut rice cake made up of its four corners gives the impression of being a scrap piece, so to speak.
This will reduce the product value.

The purpose of the present invention is to solve these problems, and its details will be explained based on the drawings. The container is shaped like a rectangular saucer with an opening 11 at the top. 12 is a general term for the rotational drive mechanism of the container 10, which includes a rotating shaft 13 hanging from the bottom of the container 10, a driving motor 14, a transmission body 15 such as a belt, chain, or gear, and a pulley 16.
17, etc., and are transmission-connected. Of course, the transmission body 15 may be omitted and the output shaft of the motor 14 may be directly connected to the rotating shaft 13.

Further, 18 is a press plate correspondingly installed so as to face the upper opening 11 of the molded container 10, and 19 is a reciprocating mechanism thereof, which is composed of, for example, a fluid pressure cylinder 20, and the press plate 18 is suspended from a piston rod 21 thereof. connected to the expression. 22 is a bearing, which supports the pressing plate 18 with respect to the piston rod 21 so that it can rotate freely. In this case, the size of the pressing plate 18 is determined to be smaller than the upper opening 11 of the container 10 so that it can move into the container 10, so to speak.

In this regard, in the illustrated example, the pressing plate 18 is moved linearly, but as long as it can press the rice cake mass A put into the container 10, it may be moved in an arc or some other method. It's okay. Further, since the movement of the pressing plate 18 is relative to the container 10, it is also possible to set the pressing plate 18 in a fixed state and to move the container 10 side. Furthermore, as shown in the modified example of FIG. 2, the reciprocating mechanism 19 is replaced with a coil spring 23,
It is also conceivable to materialize the telescopic guide rod 24 and apply back pressure to the press plate 18 by the spring. In that case, by replacing the pin 25 to the guide rod 24, the coil spring 2
It is preferable to set the back pressure by 3 so that it can be adjusted to be strong or weak. The pressure plate 18 is moved to the guide rod 2.
Needless to say, it should be connected so that it can freely rotate with respect to 4.

Using the above device, freshly pounded mochi mass A
In manufacturing the stretched mochi M, as shown in FIG. 3, first a freshly pounded mochi mass A is put into the molding container 10 as shown in the same figure, and then the mochi mass A is pressed from above. The upper opening 11 of the container 10 is pressed by the pressing plate 1 as shown in the figure.
8, and while applying the pressing force, the container 10 is closed.
It rotates.

By doing so, the mochi mass A will be evenly stretched and moved from the center position in the container 10 to the peripheral position under the synergistic effect of the pressing force and the rotating centrifugal force, and the overall It is formed into a stretched rice cake M with a uniform predetermined thickness T. After the molding is completed,
When the rotation of the container 10 is stopped, the press plate 18 is moved back to open the container 10, and the stretched mochi M is taken out from the container 10 and dried and hardened. It is also possible to dry the product while it is stored in the container 10. For example, as shown in FIG. 1, the container 10 is removably attached and fixed to a table 26 that rotates integrally with the rotating shaft 13 via a clamp 27, and the stretched mochi M is taken out together with the container 10. Because you will get it.
Note that the press plate 18 can be rotated together with the container 10.

As described above, the present invention provides a method for producing stretched mochi M, in which a freshly pounded mochi mass A is placed in a molded container 1 with an open top.
0, the press plate 18 is placed so as to close the container 10, and the press plate 18 presses the mochi mass A while rotating it, and the synergistic effect of the press force and rotational centrifugal force. Since the rice cake mass A is automatically stretch-molded under the same conditions, it has the effect of solving all the conventional problems mentioned at the beginning.

In other words, in the conventional manufacturing method where only pressing force is applied using a push rod or the like, the rice cake mass a is pushed downward, and as a result, it only stretches horizontally passively, so that the pressing force is released. When the rice cake mass a shrinks and restores itself due to its restoring elasticity, in the present invention, the pressing plate 18
While pressing down and restraining the upper surface of the mochi mass A, a rotating centrifugal force is also applied under this condition, so that the mochi mass A is moved laterally from the center to the periphery of the container 10 and actively As shown in Fig. 4, the stretched mochi M has excellent angular precision and is firmly attached to the four corners of the container 10.
It is automatically molded as

Furthermore, if we assume that the pressing plate 18 is omitted and the rice cake mass A is molded by simply rotating it in the container 10, in that case, the rice cake mass A will be thick at the periphery of the container 10 due to the rotating centrifugal force. It will be excessively stretched and moved so that it will bulge in the flesh, and conversely, the center will become thinner and the upper surface will become depressed. In this respect, in the present invention, the mochi mass A
Pressing plate 1 that closes the container 10 during the rotation action of
8 restricts the pressure on the top surface of the rice cake mass A, so that the thickness of the stretched rice cake M does not change at all, and not only the square shape accuracy at the four corner positions is accurate, but also
The thickness T can also be made uniform overall,
As a result, as cut mochi obtained from stretch mochi M,
The product value can be significantly increased.

Furthermore, the manufacturing apparatus as shown in the illustrated embodiment allows automatic and efficient molding, which is of great benefit.
