Description

[Detailed description of the invention] This invention relates to a rice cake pounding mortar in which a fixed pestle receiver is installed at the center of the bottom of the mortar body, and a rotating cylinder is arranged around the outer periphery of the fixed pestle receiver.

A mochi pounding mortar is known in which a rotatable pestle receiver is fitted into the center of the bottom of the mortar body (Patent No. 766948).
Since the punch receiver is configured to rotate, there is a risk that the impact vibration of the punch will be directly transmitted to the rotational transmission member, which is not only undesirable, but also due to the relationship between the diameter of the punch receiver and the amount of rice cake. In this connection, there was a problem that the reshaping effect was likely to be insufficient.

However, in this invention, the punch receiving body is fixed and a rotating cylinder is fitted to the outside of the punch receiving body, so that the impact force of the punch is received by the fixed punch receiving body, so that the rotation transmission member of the rotating cylinder is not affected by the impact. There is no risk of any adverse effects. On the other hand, since the pestle receiver has a relatively small diameter (for example, about 1/3 of the outer diameter of the rotating cylinder), regardless of the amount of rice cake, the rice cake will be placed on the end surface of the pestle receiver and the rotating cylinder (or on the end surface of the pestle receiver, the rotating cylinder). (tube and side wall of the mortar bottom) and receives sufficient reshaping action. When the mochi is placed on the pestle receiver, rotary cylinder, and side wall of the mortar bottom, the mochi mass is kneaded by shearing and twisting action in three different directions, or is kneaded in a complicated manner. For example, when an external force is applied to the product, it undergoes an even kneading action.
This is an improved version of the conventional mortar. Incidentally, if the mortar is rotated appropriately, rotational force can be positively applied to the above action.

Next, an example of this invention will be described.

1/2 of the diameter of the arm-shaped mortar 1 at the bottom center part of the arm-shaped mortar 1
A through hole 2 with a slightly smaller diameter is provided vertically, and a punch receiver 4 having a diameter approximately 1/3 of the inner diameter of the through hole 2 is installed upright in the center of the through hole 2. A rotary cylinder 5 is rotatably fitted tightly onto the outside of the punch receiver 4, and the upper end of a support cylinder 7 fitted to the punch receiver 4 via bearings 6, 6a is connected to the lower surface of the rotary cylinder 5. A gear 8 is fitted and fixed to the lower side wall of the support tube 7, and a gear 9 meshing with the gear 8 is fixed to the shaft of a motor 10. A water supply hole 3 is bored in the center of the punch receiver 4, and the lower end of the punch receiver 4 is fitted into the bottomed support tube 11 so as to be movable up and down. In the figure, reference numeral 12 denotes an adjustment bolt vertically screwed into the bottom plate of the bottomed support cylinder 11, and the punch receiver 4 has a key 13.
Rotation is restrained by the bottomed support cylinder. The outside of the mortar body 1 is composed of inner and outer double walls 1a and 1b, and cooling water is placed between the double walls. Also, a gear 14 is fixed to the outside of the lower part of the mortar body 1, and the gear 1
A gear 15 meshing with the motor 4 is fixed to the shaft of the motor 16. In the above embodiment, when the bolt 12 is rotated, the punch receiver 4 moves up and down as the bolt 12 moves up and down.
can be raised and lowered to adjust the position of its upper end surface. Next, when the motor 10 is started, the support tube 7 is rotated via the gears 9 and 8, so the rotary tube 5 is also rotated. Further, when the motor 16 is started, the mortar body 1 is rotated via the gears 14 and 15. The rotating directions of the mortar body 1 and the rotary cylinder 5 are the same or opposite directions, and when rotating in the same direction, it is necessary to appropriately determine the difference in rotation. However, the mortar body is sometimes used while stopped, and a mortar without a rotating mechanism is sometimes used.

In the above embodiment, if the mortar body 1 is rotated in the direction of arrow 17 and the rotary cylinder 5 is rotated in the direction of arrow 18 (in Fig. 2), external rotational forces in opposite directions are applied to the rice cake 19. At the same time, the center part is stopped on the pestle receiver, so the mochi mass is kneaded by shearing force and twisting force from the center part to the outer part. In this case, automatic (or manual) water supply is possible through the water supply hole 3 formed in the pestle receiver 4, and it is possible to prevent the rice cake from adhering to the rice cake and reliably perform the reshaping operation.

That is, according to this invention, a through hole of a predetermined size is provided vertically in the center of the bottom of the arm-shaped mortar body, a punch receiving body is fixed to the center of the through hole, and a rotary cylinder is freely attached to the punch receiving body. Since it is fitted, the impact force of the pestle is received by the fixed pestle receiver, and the mochi mass receives shearing force and twisting force by the fixed part and the rotating part (rotating cylinder), and has the effect of being sufficiently kneaded. In addition, since a water supply hole is provided in the center of the pestle receiver, water can be supplied to the rice cake mass, which has the effect of preventing the rice cake from sticking and making it possible to reliably reshape the rice cake.
