Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a molding machine for molding surimi raw materials into a fixed shape in the process of manufacturing paste products such as chikuwa and kamaboko, and particularly to a technique for pumping surimi raw materials. (Prior Art) As a conventional pastry product forming machine, one using a gear pump or a vane pump as a pump for pumping the surimi raw material to a molding die for extrusion molding the paste product is known. (Problems to be Solved by the Invention) However, when a gear pump or a vane pump is used as a pressure pump, there are problems as described below. In other words, with gear pumps and vane pumps, the surimi raw material is crushed in the pumping chamber due to its structure, which tends to cause flesh burns, and the surimi raw material being pumped creates pulsating currents, which can lead to poor molding and product failure. There was a problem that non-uniformity was likely to occur. Furthermore, since the gear pump cannot transfer solids, there is also the problem that it is limited to the use of surimi raw materials that do not contain solids. (Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and as a means for achieving this purpose, in the present invention, a pasted product is extruded and molded. In a pasted product forming machine equipped with a molding nozzle for molding, and a pump for pumping the surimi raw material to the nozzle, the pump is a pump that continues in a substantially sine curve along the outer circumferential surface of the rotor shaft. A housing including a rotor with hanging blades, an annular pumping chamber surrounded by the rotation locus of the pumping blades, and a slit that can slide closely against the outer peripheral surface of the pumping blades and provided in the pumping chamber. A sine pump was used that was equipped with a scraper gate slidably provided in the axial direction so as to partition the inside of the pumping chamber between the suction port and the discharge port. (Function) As described above, in the paste molding machine of the present invention, the pumping blades, which are continuous in a substantially sine curve along the outer circumferential surface of the rotor shaft, are used as pumps for pumping the surimi raw material to the die. A housing having a vertically installed rotor, an annular pumping chamber surrounded by the rotation locus of the pumping blades, and a slit that can slide closely against the outer peripheral surface of the pumping blades and provided in close proximity to each other in the pumping chamber. By using a sine pump equipped with a scraper gate that is slidable in the axial direction in the pumping chamber so as to partition between the suction port and the discharge port, the raw material for surimi is suctioned. After it is sucked into the pumping chamber through the mouth, it is simply pushed out from the discharge port by the scraper gate, which makes it possible to pressurize and mold the surimi raw material mixed with solids, and to prevent the surimi raw material from being ground and crushed. Since it does not get wet, there is almost no chance of flesh burns. In addition, with a sine pump, suction and extrusion are performed simultaneously on both sides of the pumping blade, and the total extrusion amount of both is always constant, so it has excellent quantitative properties and does not cause pulsation, making the product uniform. It becomes possible. (Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Note that the rotation of the cutting wire 40b is linked so that it rotates once (cuts once) with respect to the feeding of one skewer 5. Further, the pressure feeding device P is installed separately and independently from the mouthpiece 41, and a pipe 4 is connected between the discharge port 61 of the sine pump 6 and the mouthpiece 41.
3, and a hopper 42 is connected to the suction port 61. Further, a transmission 45 is interposed between the sine pump 6 and the motor 44, so that the amount of pumping of the surfacing material can be adjusted. Further, as shown in FIGS. 5 to 7, the sine pump 6 includes a rotor 62 and a housing 63.
and a scraper gate 64. The rotor 62 has two continuous pumping blades 62b extending vertically along the outer peripheral surface of the rotor shaft 62a, drawing two complete sine curves. Further, the housing 63 is arranged so that the pumping blade 6

It is provided so as to be slidable in the axial direction. Next, the operation of this embodiment will be explained. First, the operation of the sine pump 6 will be explained with reference to FIGS. 5 to 7. Since the sine pump 6 of this embodiment has the above-mentioned configuration, the annular pumping chamber 65 is divided into four independent symmetrical pumping chambers 65a by the continuous pumping vanes 62b drawing two complete sine curves. The area will be divided into sections. Therefore, the rotor 6 is rotated so that the pumping blade 62b rotates from the suction port 60 side to the discharge port 61 side.

While the surimi raw material G is vacuum-suctioned, the discharge port 61
On the side, it is compressed by a scraper gate 64 and is discharged from the discharge port 61. In this case, the scraper gate 6
4 slides in the axial direction along the sine curve of the pumping blade 62b, and the inside of the pumping chamber 65 between the suction port 60 and the discharge port 61 is always partitioned off. Further, since the sum of the cross-sectional areas of both the pumping chambers 65a, 65a divided in the axial direction by the pumping blades 62b is always uniform at any point, the discharge amount is stable and does not cause pulsation. Next, the overall operation of the chikuwa mold forming machine A will be explained. Since the bamboo ring molding machine A of this embodiment has the above-mentioned configuration, as shown in FIGS. The skewer 5 contacts the lower surface side of the belt 33 in the skewer rotating belt device 3 that moves in the opposite direction to the direction in which the locking claws 23 are transported, and is transferred while being rotated in the opposite direction to the forming drum 1.

It is fed falling into the groove 10. Then, the plate-shaped surimi raw material G that has been dropped and supplied into the forming groove 10 is guided by the forming drum 1 whose circumferential speed is faster than that of the skewer feeder, and is bitten into the lower surface of the forward groove 5 and crushed. , by rotating skewer 5
At the same time, the cylindrical outer surface of the bamboo ring T is formed by the band-shaped forming groove 10 of the forming drum 1.

A housing 6 includes a rotor 62 with pumping blades 62b vertically extending in a perfect sine curve along the outer peripheral surface of the rotor 62, and an annular pumping chamber 65 surrounded by the rotation locus of the pumping blades 62b.
3 and a slit 64a that can slide closely against the outer circumferential surface of the pumping blade 62b, and partitions between the suction port 60 and the discharge port 61, which are provided in close proximity to each other in the pumping chamber 65. By using the sine pump 6 equipped with a scraper gate 64 which is provided to be slidable in the axial direction within the pumping chamber 65, the surimi raw material G is sucked into the pumping chamber 65 from the suction port 60. After that, it is simply pushed out from the discharge port 61 by the scraper gate 64, so that the surimi raw material G mixed with solids can be pumped and molded, and the surimi raw material G is not crushed. Since there is no skin irritation, there is almost no chance of flesh burns. In addition, in the sine pump 6, the pumping blade 62
Since suction and extrusion are performed simultaneously on both sides of b, and the total extrusion amount of both is always constant, it has excellent quantitative properties and does not cause pulsation.
It becomes possible to make products uniform. Test data comparing the effects of using a sine pump and other pumps (gear pump, vane pump) is shown below.

an extrusion molding die 41 having a
Since the pressure feeding device P is equipped with a sine pump 6 that continuously supplies the surimi raw material to the hopper 42, the amount of extrusion from the molding die 41 varies depending on the amount of the surimi raw material in the hopper 42, etc. Quantitativeness can be ensured. Furthermore, by separating the pressure feeding device P from the molding nozzle 41 and placing it separately, there is no restriction on the hopper capacity, and the frequency of replenishment of the surimi raw material can be significantly reduced, and cleaning of the pressure feeding device P is possible. This makes it easier to replenish the surimi raw material into the hopper 42, thereby greatly improving work efficiency. Further, by arranging the pressure feeding device P separately, various inconveniences caused by splashing of washing water to other devices can be solved. In addition, by placing the pressure feeding device P separately, it is possible to increase the diameter of the molding drum 1 side and increase the molding distance, which increases the molding speed and increases the molding speed. It becomes possible to increase the ability of Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included. For example, in the sine pump of the embodiment, a case is shown in which the pumping vanes 62b draw two complete sine curves and are continuous, but they do not need to be complete sine curves, and the number can be arbitrary. It is. (Effects of the Invention) As explained above, in the pasted product forming machine of the present invention, as a pump for pressure-feeding the surimi raw material to the mouthpiece, a substantially sine curve is drawn along the outer peripheral surface of the rotor shaft. The housing includes a rotor with continuous pumping blades vertically disposed thereon, a housing with an annular pumping chamber surrounded by the rotation locus of the pumping blades, and a slit that can slide closely against the outer circumferential surface of the pumping blade.

After the surimi raw material is sucked into the pumping chamber from the suction port, it is simply pushed out from the discharge port by the scraper gate, so it becomes possible to perform pressure feeding and molding of the surimi raw material mixed with solids. Since the surimi raw material is not crushed, meat burn hardly occurs. In addition, with a sine pump, suction and extrusion are performed simultaneously on both sides of the pumping blade, and the total extrusion amount of both is always constant, so it has excellent quantitative properties and does not cause pulsation, making the product uniform. Effects such as being made possible can be obtained.
