CONSTITUTION:The objective skin for 'gyoza' can be obtained by making a thin circular plate form with its peripheral thickness smaller than that of the other part.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a dumpling wrapper and an apparatus for producing the same.
In particular, the present invention relates to the gyoza skin that is made with a thinner wall near the surrounding moat, and to an apparatus for producing the same.

(Conventional technology) Generally, gyoza wrappers are made from flour kneaded.
- It is made in the shape of a disc with similar wall thickness. To make gyoza, place the filling in the center of the skin, fold it back on the center line, and press the overlapping edges firmly (to make them sticky) to form gyoza.

Conventionally, gyoza wrappers are manufactured by kneading flour as the main ingredient, rolling it into a thin plate, and punching it into a disk shape using a circular die.

[Problem to be solved by the invention]

However, the gyoza wrappers made in this way are
If the meat is too thick, when it is made into gyoza, the skin becomes double at the edges where there are no fillings, reducing the deliciousness. Making the skin thinner would solve this problem, but on the other hand, if the skin is too thin, the part that wraps the gyoza filling will tear and the contents will spill out. Therefore, it is preferable to set the thickness of the gyoza skin to the minimum thickness that maintains the necessary strength in the area where the filling goes, but the strength may vary depending on the dryness of the flour used to make the skin and the amount of moisture added to it. It was difficult to set the thickness of the skin because it changed.

Further, even if such skins with different thicknesses and different amounts of squeezing are to be used, there is no conventional equipment for making them.

[Means to solve the problem]

The purpose of this invention is to solve the above-mentioned problems, and to obtain a reduction amount that is easy to manufacture and has a pleasant taste, and a manufacturing apparatus therefor. It is characterized by being formed into a thin disk shape with a thin wall.
It consists of a female mold having a circular cavity with a bottom, and a male mold consisting of a cone having a conical surface of the same length as the radius of the circular cavity, and the generating line of the male cone. is arranged in the radial direction of the cavity and rotatably supported by a support shaft, and the distance between the circular bottom of the female mold and the generatrix of the male cone is made larger than the center of the circular bottom to make the gap at the peripheral edge larger. There is a characteristic in the set point.

[Effect]

When making the amount of squeezing, the ingredients are placed in the center of the skin, folded in half, the periphery overlaps, and the overlapped area is pressed to make it stick.However, the periphery is made thin in advance, and the overall amount of yam is equal to the amount of the skin. The thickness becomes nearly uniform.

In addition, the manufacturing device puts material between the female mold and the male mold, and by rotating the cone forming the male mold around the top of the female mold, the material for the skin is squeezed in the female mold in the circumferential direction. Expand to. At this time, since the gap between the female mold and the male mold is small near the periphery, a skin with a thin drawing amount at the periphery is formed.

[Example] Hereinafter, the present invention will be explained with reference to the illustrated example. In FIG.
The wall thickness of the central portion 1b is made thinner than that of the central portion 1b. Therefore, the thickness of the skin at both the peripheral edge and the remaining portion becomes uniform depending on the amount of reduction of the molded product. In addition, in this embodiment, the peripheral edge of the squeezed skin itself has a low conical shape with the thickness gradually decreasing toward the outside, as well as a thin annular shape in which the entire peripheral edge is shaped as shown in Fig. 4. It may be formed in a so-called stepped shape.

Reference numeral 5 denotes a squeezing skin manufacturing device, in which a mold A, material supply means B, conveyance means C, etc. are supported by a frame 6.

The mold A has a female mold 7 supported downwardly on a frame 6,
It consists of a pair with a male mold 8 provided opposite to it. That is, the female mold 7 has a circular cavity 7a with a bottom.
, and can be freely raised and lowered relative to the male mold 8. The depth of the bottom surface of the cavity 7a is changed according to the cross-sectional shape of the skin to be squeezed. The male mold 8, on the other hand, consists of a pair of at least two steel cones 8a, 8a, which are placed so that their tops abut, as shown in FIG.

These cones 8a, 8a are arranged so that the generatrix of the upper surface is on the same plane, and the size is such that the generatrix is equal to the radius of the circular cavity 7a, and the generatrix is the same as the radius of the circular cavity 7a. The rotating frame 11 is supported by a support shaft 10.

The rotating frame 11 is connected to an electric motor 12 via a gear train 13, so that the support shaft 1 of the rotating frame 11
Rotate 0.

Note that 7b is an auxiliary heddle made of gauze-like thin cloth provided on the side of the female mold 7, which is slightly tensioned by rollers 7c and 7c, and is transferred in the direction of the arrow by an electric motor (not shown).

The conveying means C is made of steel and includes a large number of idle rollers 14 supported by a frame 6, one driving roller 15, and a conveyor belt 9 wound around them. It goes through between 7 and male type 8. The drive roller 15 is driven by an electric motor 16 via an intermittent drive mechanism 17 such as a Geneva mechanism, and rotates the conveyor belt 9 counterclockwise in the drawing.

The material supply means B is installed on the conveyor belt 9 and located on the upstream side of the mold A, and reduces the amount of material M for the squeezed skin to only the amount equivalent to one squeezed skin. It is weighed and dropped onto the con hair belt 9. The material M supplied onto the conveyor belt 9 is transferred onto the male die 8 by the conveyor belt 9 when the gap between the female die 7 and the male die 8 is open.

17 is a scatterer for dropping flour onto the surface of the skin material M to prevent it from sticking to the mold 7.8.

Next, the operation of this device will be explained. When the electric motor 16 is rotated, the conhair hold 9 is interlocked with the opening and closing of the mold A, and is moved counterclockwise by a predetermined amount during the open period.

Therefore, first, the material supplying means B measures an amount of material M equivalent to one piece of squeezed skin, and drops and supplies the material M onto the container held 9.
will be transferred between. As described above, during this movement, flour is sprinkled on the upper surface of the material M using the flour sprinkler 18 installed above to ensure good separation from the female mold 7.

The material M transferred between the female die 7 and the male die 8 is compressed and expanded by them when the conhair hold 9 stops. That is, the female mold 7 descends and presses the material M between it and the male mold 8. At the same time, a pair of conical bodies 8a constituting the male mold 8 rotate, and the material M is expanded in the circumferential direction within the cavity 7a. After the rotating frame 11 is rotated two to three times and the cone 8a is fully expanded, the rotation of the cone 8a is stopped and the female mold 7 is raised. At the same time, an upper auxiliary heel provided on the female mold 7 side)
By moving 7b, the finished skin 1 due to its tension falls from the cavity 7a onto the conveyor bell 1-7b and is conveyed to the next process.

In addition to the above-mentioned method of locally changing the thickness of the skin 1 with the amount of squeezing, this device can of course also be used to display a trade name or trademark using the unevenness of the surface. It is.

〔Effect of the invention〕

As described above, the skin for the squeeze amount according to the present invention is formed into a thin disc shape with the peripheral edge being thinner than other parts. Since it is made from a thin layer, the thickness of the overlapping part at the periphery can be maintained at an appropriate level, and the overall thickness of the skin can be adjusted to k=.

According to another invention, an apparatus for producing squeezed skin is formed by a female mold having a circular cavity with a bottom, and a conical body having a conical surface having the same length as the radius of the circular cavity. The male cone is arranged radially so that its generating line extends radially from the center of the cavity, and is rotatably supported by a support shaft, and the female cone is rotatably supported by a support shaft. The distance between the circular base of the circular base and the generatrix of the male cone is set to be larger than the center of the circular base, so material is placed between the female mold and the male cone, and the male By rotating the cone-shaped body around the top of the female mold, the material of the squeezed skin is spread in the circumferential direction inside the female mold. At this time, since the gap between the female mold and the male mold is small near the periphery, it is possible to easily produce a thin skin at the periphery.
