Description

  The present invention relates to a rice ball molding machine and a method for forming a rice ball, in which rice grains are difficult to adhere to a container when the rice ball is molded, and the molded rice ball can be quickly taken out from the container.

The rice ball molding machine is composed of a cylindrical guide part for containing rice and a pair of pressing parts for intruding into the inside through the openings on both sides of the guide part and pressing the rice. A rice ball is formed by forming a concave / convex pattern for preventing rice grain adhesion on the inner surface of the guide part and the inner surface of the stamp part, and pressing and hardening the rice with a pair of stamp parts. (For example, refer to Patent Document 1).
JP 2002-112901 A (see FIGS. 1 to 3)

In the rice ball molding machine of Patent Document 1, the inner surface of the guide part and the inner surface of the guide part are compared with the rice ball molding machine without the uneven pattern by forming the uneven pattern for preventing rice grain adhesion on the inner surface of the guide part and the inner surface of the stamping part. Although it is possible to avoid the rice grains from adhering to the inner surface of the mold part, in the method of forming rice balls while pressing rice against the inner surface of the guide part and the inner surface of the mold part, the difference in pressing force of the mold part and rice Depending on the cooked state of the rice, the rice grains adhere to the inner surface of the guide part and the inner surface of the stamping part, and each time the rice balls are formed, the attached rice grains must be removed, and the rice ball forming operation is troublesome. In addition to such annoying thing, when the molded rice ball is removed from the container, a part of the rice ball may be lost. Further, in the configuration in which rice is formed while pressing rice against the inner surface of the guide portion and the inner surface of the die portion as described above, the formed rice ball is in close contact with the inner surface of the guide portion. By simply removing it, the rice ball will not fall off the guide part due to its own weight, you will have to push the rice ball inside the guide part with your fingers, and from this point, the rice ball will only be cumbersome and cumbersome In this case as well, part of the onigiri is caught on the inner surface of the guide part, and part of the formed onigiri may be lost.
Also, because it consists of three members, a guide part and a pair of stamping parts, in order to take out the molded rice ball, it is disassembled from the combined state in order of one stamping part, the guide part, and the other stamping part. In other words, the rice ball molding operation has become more troublesome and cumbersome.
Furthermore, it takes a lot of time to wash the three members with rice grains after the molding is completed, and there is room for improvement.

  In view of the above-mentioned situation, the present invention intends to solve the problem that not only can the rice balls be molded in a state where some of them are not chipped, but also the molding operations can be performed quickly and easily. Furthermore, the present invention is to provide a rice ball molding machine and a rice ball molding method that can quickly perform a cleaning operation after a rice ball molding operation.

In order to solve the above-mentioned problems, the present invention has a cylindrical shape in which openings for filling rice are formed at both ends, and has three corners when viewed in the opening direction, and each plate portion connecting the corners It is possible to make the plate part of the container inwardly deformable by filling the container with rice and squeezing the container with both hands wrapped. The container is made of a synthetic resin material having flexibility. Moreover, the opening for stuffing rice has a cylindrical shape formed at both ends, and has three corners when viewed in the opening direction, and is curved so that each plate portion connecting between the corners protrudes outward. While using a flexible synthetic resin container that has a triangular shape, the plate portion of the container that is pressed by stuffing rice into the container and wrapping the container with both hands is deformed inward It may be a rice ball forming method in which a rice ball is formed by pressing.
As described above, after the rice is packed into the container through one opening and then the container is wrapped with both hands, a part or all of the pressed plate portion of the container is deformed inward, so that the container The rice stuffed on the inner surface is pressed to the center of the rice to form a rice ball. In this way, the rice is pressed to the center side of the rice on the inner side of the container and molded into a rice ball, so the rice grains are pressed against the inner surface of the container when the rice ball is formed by pressing against the inner surface of the container. This prevents the rice grains from sticking to the inner surface of the container. Moreover, after the rice ball is formed, the cleaning operation can be completed by cleaning only the container made of one member.

  A tapered surface in which the inner and outer surfaces extending from the opening at the other end of the container to the opening at the one end are expanded outwardly toward the opening at the one end so that the opening at one end of the openings at both ends is larger than the opening at the other end. You may comprise.

  The corner portion may be formed thicker than the three plate portions.

  You may give the identification means for making it distinguishable from another site | part on the outer surface of the large opening side near site | part of the outer surface of the said container.

  Just hold the container filled with rice with both hands, and the curved plate part that protrudes outward will be deformed inward to push the rice packed inside the container against the center of the rice. In addition to ensuring that rice grains adhere to the inner surface of the container and a portion of the formed rice ball is missing, it is possible not only to reliably prevent the rice ball from sticking to the inner surface of the container. It is possible to provide a rice ball molding machine and a method for forming a rice ball that can be quickly and easily removed and can easily and quickly form a rice ball that does not partially lose. Moreover, the washing operation of the rice ball molding machine can be completed by washing only the container made of one member, and the washing operation can be speeded up.

  The inner and outer surfaces from the opening at the other end of the container to the opening at the one end are tapered so that the opening at one end of the container is larger than the opening at the other end. By removing the molded rice ball from the container, the rice ball can be removed from the container by its own weight just by lightly applying it to the mounting place with the large open end side down. Rice balls can be taken out of the container.

  By forming the corner portion thicker than the three plate portions, it is possible to easily deform each plate portion while suppressing the deformation of the corner portion at the time of forming the rice ball, and there is almost no shape loss. Shaped rice balls can be easily formed with a small gripping force.

  By applying identification means on the outer surface near the large opening side of the outer surface of the container so that it can be distinguished from other parts, the molded rice ball is placed with the large opening side down as described above. When taking out from a large opening side, the large opening side can be immediately identified by simply viewing the identification means.

  1-4 shows a rice ball molding machine 1 for stuffing rice to mold rice balls. This rice ball forming machine 1 is a cylinder in which openings 2 and 3 for filling rice are formed at both ends, and has three corners 4, 5, and 6 when viewed from the opening direction, and connects the corners. Each plate portion 7, 8, 9 is composed of a container 10 having a substantially triangular shape curved outward, and the plate portion 7 of the container 10 is stuffed with rice in a state where the container 10 is packed with rice and wrapped in both hands. The said container 10 is comprised with the synthetic resin material which has the flexibility which 8 and 9 can deform | transform inside.

The container 10 is made of polypropylene. However, polyethylene or other soft synthetic resin is preferable, and any material can be used as long as the plate portions 7, 8, and 9 are deformed simply by lightly grasping the container 10. Any synthetic resin material may be used.
Further, as shown in FIG. 5, the thickness of the container 10 is such that the corners 4, 5, and 6 are thicker than the plate parts 7, 8, and 9, and when the rice balls are molded, While suppressing deformation, each plate part can be easily deformed, and there is an advantage that an almost triangular rice ball without deformation can be easily formed with a small gripping force. Thickness may be sufficient. Specifically, the corners 4, 5, and 6 have a thickness of 1.2 mm, and the plate parts 7, 8, and 9 have a thickness of 1.0 mm, but the corners 4, 5, and 6 have a thickness of 1.0 mm. It is preferable that the thickness of the plate portions 7, 8, and 9 is set in a range of 0.8 mm to 2.3 mm in terms of shape retention strength and flexibility.

  Also, as shown in FIG. 4, the opening 2 at the other end of the container 10 is such that one of the openings 2 and 3 formed at both ends of the container 10 has a size larger than that of the other opening 2. When the molded rice balls are taken out from the container 10 by forming the inner and outer surfaces 10A, 10B extending from one end to the other at the one end opening 3 into a tapered surface that expands toward the one end opening 3 side, for example, as shown in FIG. The rice ball is removed from the container 10 by its own weight on the packaging sheet S just by lightly applying it to the packaging sheet S for packaging the rice balls with the large opening 3 facing down. Although it can be taken out from the container, the inner and outer surfaces 10A and 10B may be formed as straight surfaces having the same diameter from one end to the other without forming tapered surfaces.

  Further, as shown in FIGS. 1 and 9, the outer surface 10B of the container 10 is subjected to a texture 13 as an identification means for making it distinguishable from other regions on the outer surface of the large opening 3 side. Thus, as described above, when the molded rice ball M is taken out from the container 10 with the large opening 3 side down, the large opening 3 side can be immediately identified simply by looking at the identification means 13. Yes, but no. The embossing 13 is composed of a band-shaped portion 11 formed in a specific range of the outer periphery and an arrow portion 12 formed immediately above one specific position of the band-shaped portion 11. Also good. Moreover, although the discriminating means is constituted by the embossing process 13, there is an advantage that the frictional force with the finger can be increased and the container 10 can be prevented from sliding off from the hand. It can also be configured by pasting.

  Further, the width dimension of the container 10, that is, the width dimension of the corner portions 4, 5, 6 and the plate portions 7, 8, 9 is set to be the same in the circumferential direction. It is also possible to set and implement.

  In addition, each of the plate portions 7, 8, and 9 has an arc shape that is curved with substantially the same radius of curvature so that the center portion protrudes to the outermost side in the circumferential direction. The shape may be other than the shape shown in the figure.

  Moreover, although the corners 4, 5, and 6 are formed in a curved arc shape so as to protrude outward, a straight corner portion without a curved portion (R) may be used.

  If the method of shape | molding rice ball M in the said rice ball shaping | molding machine 1 is demonstrated, first, the rice M will be packed in the container 10 through the opening 2 or 3. FIG. Thereafter, as shown in FIG. 7, the container 10 packed with the rice M is placed on one hand (left hand in the figure), and then the other hand (right hand) is moved upward as shown in FIG. 8 (a). 6, the container 10 is wrapped with both hands, and by gripping from this state, as shown in FIG. 6, some or all of the plate portions 7, 8, 9 of the container 10 are deformed inward to form a substantially straight line. By making it into a shape, the rice M is pressed against the center side of the rice M to be compacted so that a rice ball can be formed. When grasping the container 10, as described above, that is, as shown in FIG. 8 (a), as shown in FIG. As shown in FIG. 8 (b), the rice balls are pressed into a substantially triangular shape by clamping in a standing posture where the opening direction of the openings 2 and 3 is substantially perpendicular to the line connecting both palms. I am trying to do it. And the rice ball is quickly taken out from the container 10 only by lightly touching the container 10 in which the formed rice ball is stored on the packaging sheet S placed on a table not shown in FIG. Be able to. At this time, the rice grains do not adhere to the inner surface 10 </ b> A of the container 10, and a part of the rice ball is not lost. The rice balls taken out in this way are packaged in the packaging sheet S, but may not be packaged in the packaging sheet S. The packaging sheet may have any configuration such as an existing configuration, and a specific description thereof will be omitted.
