Is described.
JP-A-7-155146 Japanese Utility Model Publication No.5-2695

  In the case of foods such as dumplings and small rice cakes, the inner material is hand-wrapped with a sheet-like outer shell material, so when gathering the peripheral portion of the outer shell material so as to squeeze it together, the peripheral portion overlaps in a bowl shape And sealed. It is widely recognized by consumers that the appearance formed in such a bowl shape is characteristic of these foods.

  Therefore, also in the above-mentioned prior art, brazing is performed using a mold at the time of molding. However, when brazing is performed using a mold, the shape of the heel becomes a constant shape, resulting in a poor hand-wrapping shape. In addition, there is a problem that a complicated mold for forming the brazing is required, and a precise mechanism for accurately setting the outer skin material on the mold is required.

  Then, an object of this invention is to provide the food shaping | molding apparatus which can shape | mold the food with the characteristic in a simple structure in the shape which has a hand-wrapping feeling.

  The food molding apparatus according to the present invention has an opening and a receiving member on which a sheet-like skin material is placed, and a skin formed by moving a central portion of the skin material downward from the opening to form a bowl shape A material forming means, a sealing means arranged above the receiving member and arranged to gather and seal the peripheral edge portion of the outer skin material formed by a plurality of shutter pieces, and arranged below the receiving member And an embossing means for embossing and shaping the sealed upper part. Further, the outer skin material includes a streaking means for forming a plurality of thin-walled thin portions at least at a peripheral portion of the outer skin material, and the outer skin material forming means includes It is characterized by being brazed so as to be bent. Furthermore, the outer skin material forming means includes a pushing means for pushing the outer skin material into the opening. Further, the pushing means includes an inner material supplying means for supplying an inner material. Furthermore, the mold pressing means includes a pair of mold pressing members that linearly press from both sides of the sealed upper portion. Furthermore, a support means for supporting the outer skin material is provided below the embossing means.

  By having the configuration as described above, the outer skin material placed on the receiving member is formed into a bowl shape, and the peripheral edge portion is gathered and sealed, and the sealed upper part is formed by embossing, It can be molded into a shape with a feeling of hand-wrapping while suppressing damage to the outer skin material. In other words, the upper part where the peripheral parts are gathered and sealed is stamped and shaped so that the lower part of the molded food is finished in a natural rounded shape that encloses the inner material, and the upper part is finished by stamping. It can be finished in a shape that characterizes food. In particular, in the case of food that finishes in a shape close to an ellipse when viewed from above, it becomes a shape that is close to a circle when the peripheral edges are gathered together and sealed, but by shaping the upper part by embossing, it becomes a shape that is close to an ellipse It can be finished.

  For example, when handmade dumplings, the periphery of the dumpling skin is overlapped and sealed, so the whole is elongated along the sealed part, and the inner material is wrapped around the sealed part except for the sealed part. The sealing portion has a characteristic outer shape that is in close contact so that the outer skin material can be held together. In that case, the sealed upper part can be shaped by embossing to form a characteristic outer shape that is elongated along the sealed part.

  And it is provided with the creasing means which forms a plurality of thin line-like thin parts in at least a part in the peripheral part of the outer skin material, and the outer skin material forming means is bent at the thin wall part in the peripheral part when forming the hook-like shape If it is brazed, it can be brazed in the sealing part of a dumpling. At that time, the bent shape at the thin wall portion slightly changes, so that the brazing is not finished in the same shape and can be formed into a shape with a feeling of hand-wrapping.

Yes. A plurality of blow holes 24b are formed in the central portion of the recess 24a. After punching, air is blown from the blow holes 24b to smoothly separate the outer skin material from the upper mold 24. Yes. An air supply device (not shown) is connected to the blow hole 24b via an attachment member of the upper mold 24, and is controlled so as to eject air at an appropriate timing during the stamping operation. In addition, an extruding piece having an extruding surface along the mold surface on the lower surface may be provided so as to be movable up and down, and the extruding piece may be operated to separate the outer skin material during the stamping operation.

  FIG. 5 is a plan view (FIG. 5A) and a BB cross-sectional view (FIG. 5B) regarding a pair of mold pieces 29 constituting a horizontal mold. The mold pieces 29 each have a concave surface 29a having a semicircular shape in plan view and are formed sideways. When the pair of mold pieces 29 are abutted so that the concave surfaces 29a face each other, the concave surfaces 29a are connected to each other to form the upper mold. A circular space substantially corresponding to the outer shape of 24 is formed.

  6-10 is explanatory drawing regarding the stamping process by the stamping mechanism 2. FIG. First, as shown in FIG. 6, the upper die 24 is raised and the pair of horizontal die pieces 29 are opened and raised. Then, the sheet-like outer skin material F <b> 1 is conveyed by the belt conveyor, positioned below the upper mold 24, and stopped.

Therefore, the outer skin material F2 is pushed into the opening 41 to be bent in a bowl shape. At that time, the pressed outer skin material F2 is supported by the support member 70, and the peripheral edge portion of the outer skin material F2 protrudes above the opening 41. FIG. 32 is a perspective view showing a state in which the peripheral edge portion of the outer skin material F <b> 2 protrudes from the opening 41. Since the outer skin material F2 is in a squeezed state when it is pushed in, the outer skin material F2 is bent and folded so as to be bent at the thin-walled portion S, and the hooked portion W is formed. After the discharge nozzle 5 is lowered, the valve 50 that closes the discharge hole is raised and the inner material G can be discharged from the discharge hole.

  In FIG. 28, the valve 50 is raised while raising the pushed discharge nozzle 5, and the inner material G is discharged from the nozzle 5 toward the outer skin material F2. The discharged inner material G in a predetermined amount is held in the outer skin material F2 formed in a bowl shape.
