Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an automatic rice cake pounding machine used in food processing industries such as confectionery, rice cake, etc.

(Prior art) There are various types of mochi pounding machines, but the present invention is disclosed in Japanese Patent Publication No. 49-27349, Japanese Utility Model Publication No. 155300-1977, and Japanese Utility Model Publication No. 51-
It belongs to the type such as No. 110091 in which a rotating body is provided at the inner bottom of the mortar body. Those with a rotating body at the inner bottom of the mortar use the rotary body to roll the mochi inside the mortar, eliminating the need for turning and pounding the mochi evenly with the pestle. It is.

However, a rotating body is required to perform two contradictory functions. That is, during the mochi pounding process, the mochi is properly bonded to the mochi so that the rotational force of the rotating body is effectively transmitted to the mochi inside the mortar, and when the mochi pounding is finished, the mochi is not glued to the mochi so that it can be easily removed from the mortar. It's better to have one.

Therefore, the inventor of the present invention previously proposed coating the surface of the rotating body with a fluororesin coating and forming grooves on the outer periphery of the surface (Utility Model Application No. 62-94794).

(Problem to be solved by the invention) As a conventional technique, the surface of the rotating body is treated with fluorine resin to prevent rice cakes from adhering to it, and radial grooves are formed so that the rice cakes can be caught and rotated through the grooves. I have to. However, when the rotational force of the rotating body is transmitted to the rice cake, centrifugal force naturally acts on the rice cake, and there is a risk that the rice cake will deviate from the center of the rotating body, where the pestle falls, so that effective punching may not be possible. Also, the finished state of mochi differs depending on its intended use; for example, if the mochi is to be used for a large skin, the mochi is pounded many times with a pestle, resulting in a so-called firm mochi. However, when the mochi loses its elasticity and becomes very elongated, it tends to stick to the rotating body, which makes it inconvenient to take out the mochi, and it ends up wrapping around the outer peripheral side of the rotating body that protrudes from the bottom of the mortar body. There are cases. Even if the rotating body is treated with fluorine resin to prevent the mochi from sticking, if the adhesion of the mochi is weak, the rotational force of the rotating body will not be transmitted to the mochi, and as the number of punches increases, the mochi will stick to the mochi. If the adhesion force increases, the mochi may adhere to the rotating body, resulting in a problem.

(Means for solving the problem) This proposal proposes further improvements in view of the above-mentioned problems.

The automatic mochi pounding machine according to the present invention has a rotary body at the center bottom of the mortar body, and the pestle moves up and down toward the rotary body within the mortar body. A suitable number of concave grooves are formed radially on the outer periphery of the upper surface of the rotating body whose surface is made of fluororesin, and an uneven strip is provided on the upper surface of the rotating body to resist the centrifugal force of the rotating body. That is.

Further, the rotating body is characterized in that an uneven strip is provided on the outer peripheral side surface of the surface protruding from the bottom of the mortar main body.

(Function) When the adhesion force of the mochi is weak, even if centrifugal force is generated on the mochi due to the rotation of the rotating body, the uneven stripes prevent the mochi from transferring to the inner wall surface of the mortar due to the centrifugal force, and the mochi becomes sticky. Since the rice cake is caught in the groove and rotated well, a part of the rice cake is always located at the part where the pestle falls, and the rice cake is rotated along the wall surface of the mortar and is turned back. Further, even if the adhesion of the rice cake increases as the punching progresses, the unevenness on the surface of the rotating body, particularly the unevenness on the outer peripheral side surface, prevents the attachment of the rice cake (rolling of the rice cake).

(Example) Next, an embodiment of the present invention will be described based on the drawings.

The automatic mochi pounding machine according to the present invention is composed of a mortar mechanism and a pestle mechanism. A rotary body 4 connected to a rotary shaft 3 is positioned, and a mortar body 6 having a bowl shape and provided with a through hole 5 that matches the outer diameter of the rotary body 4 is placed on the mortar base 1. The punch mechanism uses a crank (not shown) or the like to move the punch body 7 up and down above the rotating body 4. In particular, the surface of the rotating body 4 is coated with fluorine resin or a fluorine resin coated plate. The surface is formed of fluororesin as shown in FIG.
2.

Then, put the steamed sticky rice into the rotary body 6, and turn the rotary body 4.
When rotated, the sticky rice lumps stick to the inner surface of the mortar body 6, and a part of the sticky rice lumps enters and gets caught in the concave groove 41 of the rotating body 4, and also gets caught on the uneven strips 42, so that the sticky rice becomes sticky. The rotational force of the rotating body 4 is sufficiently transmitted to the mass,
Since the rice cake rotates while repeatedly coming into contact with the inner wall surface of the mortar body 6 and peeling off the adhesive, the sticky rice mass moves within the mortar body 1 as if being kneaded, and a part of the rice cake is struck by the pestle body 3. The rice cakes are then gradually formed into rice cakes.

Note that a mortar body drive mechanism for rotating the mortar body 6 in a direction opposite to that of the rotating body 4 may be attached as necessary. Furthermore, the uneven strips 42 are not necessarily formed in concentric circles, but even if the sticky rice mass is subjected to centrifugal force acting outward from the mill due to the rotation of the rotating body 4, the unevenness strips 42 are not necessarily formed in concentric circles, but are designed to prevent the mochi from moving due to the centrifugal force. It is sufficient if it is provided in the direction in which the blocking action is performed.

FIG. 3 shows another embodiment of the present invention, in which a rotary body 8 whose surface is made of fluororesin is provided with uneven strips 81 on the outer peripheral side. When attached to a machine, it becomes a mochi pounding machine that is especially suitable for manufacturing soft mochi with elasticity by making many punches. In other words, if a block of mochi rice is pounded with a pestle for a long time, the mochi will become soft and elongated, making it suitable for use as daifuku wrappers, etc. However, the adhesive strength of the mochi will become stronger, especially at the bottom of the mortar body. becomes wrapped around the outer peripheral side surface of the rotating body 8 which protrudes further. However, the uneven strips 81 reduce the adhesion force of the rice cake to the rotating body 8, and prevent the rice cake from being wrapped around the rotating body 8.

Furthermore, as shown in FIG. 4, the present invention provides a rotary body 9 whose surface is made of fluororesin, a groove 91 is provided on the outer periphery of the upper surface, and an uneven strip 92 is provided on the upper surface.
It is also possible to provide uneven strips 93 on the outer circumferential side surface, and in this case, it is possible to handle rice cakes ranging from glutinous rice lumps with weak adhesion to soft rice cakes with strong adhesion.

(Effects of the invention) As described above, this invention has a rotary body inside the mortar, and in an automatic mochi pounding machine that uses the rotary body to turn the mochi at the same time as the mochi pounding operation, the rotary body surface is made of a soft material that is difficult for mochi to adhere to. It is made of resin and has radial grooves on the outer periphery of the top surface, as well as uneven stripes on the top surface to ensure that the action of the rotating body is transmitted to the rice cake during the mochi pounding operation.
This improves the efficiency of rice cake making work.
In addition, uneven stripes are provided on the outer circumferential surface of the rotating body to prevent mochi, which is soft and has a strong adhesive force, from wrapping around the rotating body. This problem was solved.
