Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is a method of preliminarily shaping dumpling dough that is continuously extruded with a predetermined width and thickness by an extrusion device and cutting it into dumpling blocks. This invention relates to a preforming device for a dumpling making machine.

[Conventional technology]

Conventionally, as a dumpling manufacturing machine, a preforming device with two forming rolls arranged side by side is placed below an extrusion device that continuously extrudes the dough for dumplings to a predetermined width and thickness. A skewering device for skewering the dough being preformed is installed next to the device, and below the preforming device, the dumpling mass sent from the preforming device is formed on the arc-shaped surface of the finishing table. A finishing device is installed between the finishing groove formed on the circumference of the finishing roll and the finishing groove formed on the circumferential surface of the finishing roll, and finishes the finishing roll into a spherical shape by rotating the finishing roll relative to the finishing table. There is a known method in which forming rolls are intermittently rotated in opposite directions, and a skewering device is operated while the forming rolls are stopped to pierce the dough being preformed with a skewer (Japanese Patent Publication No. 56-42247 Publication No.).

[Problem that the invention seeks to solve]

However, as mentioned above, in the conventional dumpling making machine, the two forming rolls of the preforming device are
It rotates intermittently and while it stops, insert a skewer into the dough.
In addition, because the dough is divided into lumps using two forming rolls and sent to the finishing device, the production efficiency is low and only about 40 balls can be produced per minute at most, and the dough cutting function is poor. There was a problem in that it was not possible to accurately divide highly viscous dough or dough that was continuously fed quickly.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides grooves formed by flanges around a forming roll having a large number of recesses lined up in the circumferential direction and width direction on the outer peripheral surface of the forming roll. The fabric, which is provided corresponding to the rows of recesses in the circumferential direction and is continuously extruded from the extrusion device to a predetermined width and thickness, is rotated in the opposite direction to the forming roll to preliminarily extrude it in cooperation with the forming roll. A blade is cut into the outer circumferential side of the presser roll that is to be formed, and the outer circumferential side of the preformed dough that rotates in the same direction as the presser roll and is continuously fed out from between the forming roll and the presser roll to cut approximately the outer half. a first cutting member that rotates in the opposite direction to the first cutting member and cuts the preformed dough fed from between the forming roll and the first cutting member into dumpling lumps together with the first cutting member; The first cutting member and the second cutting member each include a plurality of blades that rotate about an axis, and the rotation locus of these blades are arranged so that they are in contact with each other, and a plurality of blades provided on the first cutting member are arranged along the rotation direction at mutual intervals that are approximately equal to the length of the dumpling in the feeding direction, and the second cutting member A plurality of cutters provided on the member are arranged along the rotation direction at intervals sufficiently larger than the length of the dumpling in the feeding direction.

[Effect]

The dough that is continuously extruded from the extrusion device to a predetermined width and thickness enters between a forming roll and a presser roll, and is preliminarily formed by these rolls. At this time, the inner half of the dough that has entered between the forming roll and the presser roll enters the recess formed on the outer circumferential surface of the forming roll, and the outer half enters the groove of the presser roll and feeds the dough using the flange. You can make cuts in the direction. The dough preformed by the forming roll and presser roll in this way is fed between the forming roll and the first cutting member, and its outer half is cut by the blade of the first cutting member,
Furthermore, it enters between the first cutting member and the second cutting member and is divided into lumps by their cooperative action. Further, the plurality of blades constituting the first cutting member, together with the forming roll, divide the dumpling dough into pieces of approximately the same size as the size to be formed, and the plurality of blades constituting the second cutting member divide the dumpling dough into pieces that are approximately equal to the size to be formed. Since the spacing is sufficiently large, the dango can be separated reliably against the adhesive force of the dango dough.

Next, the operation of the preforming apparatus according to the present invention configured as described above will be explained together with the operation of the dumpling making machine.

Start the drive device F and move the extrusion rolls 2 and 3.
When the forming roll 23, finishing roll 119, etc. are rotated and the dumpling dough is put into the hopper 1 of the extrusion device A, the dough is transferred from between the extrusion rolls 2 and 3 to the bottom plate by the rotation of the extrusion rolls 2 and 3. 5 through the through hole 4. At this time, the thickness of the fabric is regulated by the thickness adjustment plate 6, and the width of the fabric is regulated by the width adjustment plates 7 and 8.
The fabric is continuously extruded downward to a certain thickness and width, and is prevented from shifting in the width direction by guide rolls 9 and 10, and then transferred to sizing rolls 21 and 2.

From 1 and 22, the dough is fed between the forming roll 23 and the uppermost presser roll 24, and then transferred to the cutting mechanism 2.
After that, the pressing member 85 gradually retreats to pull out the push rod 81 from the holding groove 77, returning to the initial state. After the push rod 81 is retracted, a skewer k is supplied to the holding groove 77 from a skewer supply device E in a well-known manner.

The dough pierced with the skewer k in this way reaches the cutting mechanism 25, where its outer half is first cut by the blade 28a of the cutting member 28 rotating in the same direction as the presser roll 24, and then the forming roll 23 The dumplings are divided into lumps by the joint action of the blade 29a of the other cutting member 29 rotating in the same direction as the cutting member 28, and the blade 28a of the cutting member 28. This dumpling mass is guided to the finishing device D by a scraping roll 123, and is then guided to a finishing table 118.
By rotating the finishing roll 119 against the ball, the dumplings are finished in a well-known manner.

In order to reduce the amount of stabbing of the skewer k into the fabric in the above, operate the handle 91 to move the skewer roll 79 backward along with the movable shaft 73 and the support member 74 in the axial direction of the movable shaft 73. Forming roll 2

A blade is bitten into the outer periphery of a presser roll that jointly performs preliminary forming, and the preformed dough that rotates in the same direction as the presser roll and is continuously fed out from between the forming roll and the presser roll. A first cutting member that cuts the outer half of the warp, and a preformed dough that rotates in the opposite direction to the first cutting member and is sent out from between the forming roll and the first cutting member, together with the first cutting member. A second cutting member that cuts the dough into dumplings is provided, and first, the outer half of the dough is cut by the blade of the first cutting member rotating in the same direction as the presser roll, and then the inner half of the dough is cut. Since the blade of the first cutting member and the blade of the second cutting member are configured to cut and forcibly divide the dough into lumps, the viscosity of the dough may be high, and the dough may Even when the dough is fed out so quickly and continuously, it can always accurately divide the dough into lumps. Therefore, the dough can be preformed by continuously rotating the forming rolls, and the efficiency of producing dumplings can be increased. In addition, since the first cutting member is provided with a plurality of blades spaced apart from each other at approximately the same distance as the dumplings to be produced, it is possible to reliably form the dough into a predetermined shape in cooperation with the forming rolls. In addition, since the second cutting member is provided with a plurality of blades at intervals sufficiently larger than the length of the dumplings to be produced,
It is less likely that the dumpling dough will stick between the blades, resulting in poor cutting, and therefore the dumpling dough can be reliably divided even during high-speed operation.
