Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pressing die in a cooked rice forming apparatus.
[0002]
[Prior art]
Conventionally, a turntable provided with a plurality of molds penetrating in a vertical direction with a certain interval in the circumferential direction is pivotally supported on the machine base, and as a push mold on both upper and lower sides of the mold of the turntable, 2. Description of the Related Art A cooked rice molding apparatus is known in which an upper mold and a lower mold for pressing and molding cooked rice filled in the mold are arranged so as to be movable up and down.
[0003]
However, according to the above-described conventional cooked rice forming apparatus, since both the upper mold and the lower mold of the pressing mold are made of metal or hard plastic, each pressing surface is formed entirely smoothly, The surface of the shaped cooked rice looks like a press-molded product manufactured by a machine, and the texture and taste of the cooked rice deteriorates because the entire cooked rice is over-pressed and hardened more than necessary. Of course, a decline in product value was inevitable.
[0004]
The present invention has been made in view of the above-described problems of the prior art described above. By providing a large number of concave and convex portions on the pressing surface of the pressing die, the surface of the shaped cooked rice has a small hand grip. An object of the present invention is to provide a stamping die in a cooked rice molding apparatus that can form irregularities and is soft, excellent in texture and taste, and having a high commercial value.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the pressing die in the cooked rice forming apparatus according to the present invention includes an upper die and a lower die that press and mold the cooked rice filled in a forming die having a predetermined planar shape from above and below. The cooked rice molding apparatus is characterized in that a large number of concave and convex molded portions with respect to the surface of the shaped cooked rice are formed on the pressing surfaces of the upper mold and / or the lower mold.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a partially sectional front view showing an embodiment of a cooked rice forming apparatus equipped with a pressing die according to the present invention, and FIG. 2 is a partially sectional front view of the same pressing die when pressing rice. FIG. 3 is a bottom view of the upper mold in the upper push mold, FIG. 4 is a partial sectional view taken along line AA in FIG. 3, and FIG. 5 is a bottom view of the lower mold in the upper push mold. 6 is a partial cross-sectional view taken along the line B-B in FIG. 5, FIG. 7 is a front view of the formed cooked rice, and FIG. 8 is a front view of the formed cooked rice with laver sheets pasted on both upper and lower surfaces. .
[0007]
1 and 2, reference numeral 1 denotes a support plate arranged horizontally on a machine base (not shown), and 2 denotes a disc-shaped turntable that is rotatably supported on the upper surface of the support plate 1 in a horizontal state. The turntable 2 is formed with a plurality of molding dies 3 penetrating in the vertical direction at regular intervals in the circumferential direction.
[0008]
In the present embodiment, the planar shape of the mold 3 is substantially triangular as illustrated in FIG. 3 and the following figures, but is not limited thereto, and may be formed in a circular shape, a rectangular shape, or the like.
[0009]
When the mold 3 of the turntable 2 stops at a predetermined position, a predetermined amount of cooked rice a placed on the upper surface of the conveyor 4 is pushed by the pusher 5 and charged into the molding method 3 for filling.
[0010]
As a means for supplying the cooked rice a to the mold 3 of the turntable 2, the cooked rice is compressed and transferred from the upper cooked rice hopper to the vertically arranged feed rollers in addition to the conveyor 4 and the pusher 5 described above. It is also possible to employ a roller-type cooked rice supply mechanism (not shown) that is cut into a predetermined amount.
[0011]
When the mold 3 of the turntable 2 stops at a predetermined position, the upper mold is used as a mold that presses and molds the cooked rice a filled in the mold 3 to a predetermined thickness and hardness from both upper and lower surfaces. 6 and a lower die 7 are supported on the upper and lower sides of the forming die 3 of the turntable 2 by arms 8 and 9 interlockingly connected to an elevation drive mechanism (not shown) and arranged to be movable up and down.
[0012]
As shown in FIGS. 3 to 6, each of the pressing surfaces of the upper die 6 and the lower die 7 facing each other is provided with concave portions 10 and 11 having a slow arc shape, and the concave portions 10. , 11 is formed with a large number of concavo-convex molded portions 12..., 13.
[0013]
In the illustrated example, each of the concave and convex portions 12..., 13... Is formed with arcuate concave surfaces 12 a, 13 a..., And various long and short oval grooves 12 b. However, it is not limited to such a shape, and for example, it may be formed in a circular shape, a triangular shape, a square shape, or other polygonal shapes.
[0014]
As described above, the planar form, the arrangement form, the depth (height), etc. of the concavo-convex molded parts 12... 13 are not limited, but the total area on the concave side and the total area on the convex side are as equal as possible. It is desirable to consider so that the uneven portion c is evenly obtained on the surface of the shaped cooked rice b as shown in FIG.
[0015]
In the illustrated example showing the present embodiment, a large number of concave and convex portions 12... 13 are formed on both pressing surfaces of the upper die 6 and the lower die 7, and this is desirable, but the upper die 6 or the lower die 7. The concave / convex molded portion may be formed on only one of the two.
[0016]
In such a configuration, the cooked rice a filled in the mold 3 is pressed from above and below by the upper mold 6 and the lower mold 7 to be formed as the molded cooked rice b. As shown in FIG. 4, the upper and lower surfaces of the upper and lower molds 6 and 7 are respectively provided in a convex manner in the form of a slow arc upward and downward by the concave surface portions 10 and 11, and the concave and convex portions 12. As a result, a large number of uneven portions c are formed.
[0017]
The molded boiled rice b molded in this way has not only a hand-grip-like appearance and soft feeling on the surface, but also a laver sheet d on both upper and lower sides of the shaped boiled rice b as shown in FIG. When d is pasted, since the contact area with the shaped cooked rice b is small, stickiness due to moisture absorption of the laver sheets d and d can be reduced.
[0018]
【The invention's effect】
The present invention has the above-described configuration, and includes an upper mold and a lower mold that press and mold the cooked rice filled in the mold from above and below, and these upper mold, lower mold, both pressing surfaces, or one pressing surface. In addition, since a large number of concavo-convex molded portions are formed on the surface of the molded cooked rice, the molded cooked rice pressed and molded by this concavo-convex molded portion can form a large number of hand-held concavo-convex portions on the surface. It is possible to perform mechanically efficient finishes and not harden more than necessary due to excessive compression, so it is possible to automatically mold high quality cooked rice that is soft, textured and excellent in taste, etc. It is what has.
