Description

[Detailed description of the invention] The present invention relates to a rice cake pounding machine.

A mochi pounding machine generally requires a large force for the impacting force of its pestle, but when the pestle is in a rotating form, it is difficult to obtain a large impact force.

The present invention is intended to eliminate such defects, and for this purpose, the following technical measures have been taken.

That is, a mochi pounding chamber 11 located above a spiral chamber equipped with a spiral 2 that collects mochi and pushes it upwards through rotation is used to press mochi that is pushed up from the lower spiral chamber through rotation.
The rice cake pounding machine is provided with a bendable mallet 3 so as to be able to escape from the restoring position against the spring 8 due to the resistance at the time of striking.

With this configuration, the present invention has the following technical effects.

That is, by the 20 rotations of the spiral, the mochi in the spiral chamber is collected and pushed up into the range of rotation of the pestle 3 in the mochi pounding chamber 11 above the spiral chamber, and is pressed by the rotation of the pestle 3. However, since the pestle 3 has a spring 8, when pounding the mochi, the rotational force of the pestle 3 and the restoring force of the spring 8 are used to effectively apply the pounding pressure, and the mochi can be pounded more effectively. Immediately after pressing the rice cake, the rod 3 escapes against the spring 8 due to this pressing resistance, so that the pestle 3 shreds the rice cake at the time of pressing and scrapes it away in the direction of rotation. In addition, the 30 rotation range of the punch can be brought as close as possible to the spiral chamber side to enhance the mochi pounding action.

If a discharge port 16 that can be opened and closed is provided at the bottom of the spiral chamber, by opening this discharge port 16 every time the mochi pounding operation is completed, the mochi inside will be removed from the machine through the bottom discharge port 16. After taking out the rice cake, the discharge port 16 is closed again and new rice cake is supplied, so that the rice cake can be pounded continuously and efficiently.

Further, at the mochi supply port 12 of the mochi pounding chamber 11, there is a mochi kneading machine which has a rotatable spiral 6 in the cylinder and pushes out the mochi supplied from the omper 1 at the top of one end while kneading it from the discharge port at the other end. When looking through the outlet, the mochi, which has been kneaded by the 60 rotations of the spiral, is supplied to the mochi pounding chamber 11 and the spiral chamber below this for pounding, so that the mochi pounding can be completed more quickly. Even if the mochi contains small air bubbles when being kneaded with the spiral 6, it will be subjected to the pounding pressure of the pestle 3 in the mochi pounding chamber 11.
The air bubbles are expelled and a so-called chewy mochi is obtained.

In addition, if a guide bank 9 is provided in the rotating gap between the spiral 2 and the pestle 3 on the side wall of the mochi pounding chamber 11, which protrudes inward in a wave-like manner and guides the mochi inward from the side wall surface, the spiral 20 turns. The rice cakes being transferred toward the left and right side walls are fed into the area of the pestle 3 on the mochi pounding chamber 11 side along the guide bank 9 that protrudes from the spiral chamber in a wave-like manner, and the rice cakes are pounded by the pestle 3. can be carried out effectively.

Moreover, since the mochi is pushed toward the center of the mochi pounding chamber 11, a large portion of the mochi pounded by the mallet 3 also moves toward the center, and therefore the circulation in the spiral chamber and the mochi pounding chamber 11 is reduced. It's smooth.

Moreover, in the upper part of the spiral chamber 11, between the mochi supplying bottom surface which slopes downwardly toward the top of the spiral 2 from the upper mochi supply port 12 and the inside of the spiral chamber, mochi is supplied and guided to the central part of the spiral 2. When the guide groove 5 is provided, the rice cake supplied from the upper supply port 12 is completely guided through the guide groove 5 on the supply bottom and is supplied to the center of the spiral chamber, and the rice cake is fed from the guide groove 5 to the left-right spiral. 2
Since it is transferred to both the left and right sides by zero rotation, the transfer within the spiral chamber is ensured.

Moreover, the return of the rice cake from the rice cake pounding chamber 11 to the central part of the spiral chamber is also carried out smoothly.

In addition, if a discharge port 16 that can be opened and closed is provided at the center of the bottom of the spiral chamber, and the spiral 2 is provided so that the forward and reverse rotation directions can be switched,
When pounding the mochi, the discharge port 16 is closed and the spiral 2 is rotated in the forward direction to perform the normal mochi pounding action, but once the mochi has been pounded, the spiral 2 is rotated in the opposite direction to rotate the mochi from side to side. Since the transfer can be completed from both sides toward the center, the discharge port 1
By opening 6, the pounded rice cake is discharged from this outlet 16.
The mochi inside the spiral chamber can be smoothly discharged.

In addition, if a water supply port 10 is provided in the spiral chamber or the mochi pounding chamber 11, the mochi being pounded is appropriately injected with water, and the mochi is poured onto the wall surface of the mochi pounding chamber 118, the spiral 20 phase, and the spiral chamber. Men or pestle 3
By making it difficult to adhere to the surrounding surface, a clean mochi pounding action can be maintained.

In the illustrated example, the spiral 2 has a left-handed spiral and a right-handed spiral symmetrically on both left and right sides from the central part, and a punch 3 is provided near both left and right ends of the shaft 14 in close proximity to this spiral 2. The shaft of the punch 3 and the shaft 14 of the punch 3 are mounted on the left and right sides of the machine body 13, and both are linked to the deceleration motor 4 by a belt 15 or the like.

Inside the fuselage 13, a mochi pounding chamber 11 is provided at the top in which the pestle 3 is housed, and a spiral chamber in which the spiral 2 is housed is provided at the bottom of this mochi pounding chamber 11, which communicates with the mochi pounding chamber 11 on the upper side of the spiral 2 chamber side. A supply port 12 is provided in the chamber 11, and a mochi pounding chamber 11 is provided below the supply port 12.
A downwardly sloping supply bottom surface is formed in the interior of the spiral chamber so that the lower end thereof can be seen above the spiral 2, and an overhanging passage is provided on this supply bottom surface in order to provide a guide groove 5 that directly shorts into the spiral chamber at the left and right center position. It is recessed.

A lid 17 is provided over the discharge port 16 in the center of the spiral chamber.

The pestle 3 has a chamfered portion 7 on its rotation side, and is configured to be bent by a spring 8 and by resistance to striking force, and to be able to return to its original state after the force is applied when the resistance disappears.

Wave-shaped guide banks 9 are protruded on both left and right walls between the spiral chamber and the mochi pounding chamber 11, and the side walls facing the rotating part of the pestle 2 and the side walls near the shaft 14 of the spiral 2 A water supply port 10 for supplying water in the form of a spray is provided in the hole.

The cylinder body housing the spiral 6 has a pumper 1 connected to the top of one end thereof, and a discharge port is provided at the other end, and the discharge port is exposed above the supply port 12.

When steamed glutinous rice is supplied to the hopper 1, it is compressed while being conveyed through the cylindrical body through 60 spiral rotations, and is passed from the discharge port through the supply port 12 to the guide groove 5 on the supply bottom of the mochi pounding chamber 11. In the spiral chamber, the mochi is fed to the central part of the spiral chamber, and by the forward rotation of the spiral 2, the mochi is transferred to both left and right sides, reaching both side walls 9, and along the wave-shaped guide bank 9 to the upper mochi pounding chamber 11. The mochi is pushed up into the range of 30 rotations of the pestle inside, and is pressed by the 30 rotations of the pestle, and the pressed mochi is drawn into the range of 20 rotations of the spiral and returns to the range of 30 rotations of the pestle in the upper mochi pounding chamber 11. The punch 2 is pushed up and subjected to repeated striking pressure, and the punch 2 at this time of striking pressure is able to escape by the spring 8 due to the striking resistance, and the punch 2
When the punch 3 rotates further and is located outside the range of resistance exerted by the rice cake, the pestle 3, which has no longer any resistance to pounding the rice cake, is restored by the spring 8 and once again hits the rice cake pushed up from the spiral chamber.

In this way, the mochi is transferred from the center of the spiral chamber to both left and right sides, and during this time, the mochi kneading action is also performed, and from both ends, the mochi is passed through the mochi pounding chamber 11 within the range of 30 revolutions of the pestle, and then to the lower spiral chamber. The rice cake goes through a cycle that returns to the center, and during this time, the rice cake becomes a firm, high-quality rice cake with few air bubbles inside.

By pounding the rice cakes, the lid 17 of the discharge port 16 is opened, and the spiral port 2 is rotated in the opposite direction, whereby the rice cakes collected in the spiral chamber are taken out from the central discharge port 16.
