Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an improvement in a method for manufacturing a die for extrusion manufacturing spaghetti.

(Conventional technology) To make spaghetti, raw materials such as flour are made sticky with water and extruded through a die. For example, if the die is made only of metal, the sticky raw material will stick to the extrusion hole of the die and become difficult to separate. Due to the fact that it is difficult to obtain a smooth gloss, etc.
A spaghetti extrusion die is used in which a chip of polytetrafluoroethylene (commonly known as Teflon) is arranged in the spaghetti extrusion hole of the die.

This spaghetti extrusion die has a chip 2 with a spaghetti extrusion hole 1 pre-drilled in the center as shown in FIG. The chip holder 7, which has an introduction hole 5 and a tapered guide hole 6, is pressed into the chip holder.

(Problems to be Solved by the Invention) However, in the above manufacturing method, when the chip 2 having the spaghetti extrusion hole 1 is pushed into the chip insertion hole 4 of the die body 3, the chip 2 becomes as shown in FIG. Since compressive force is applied from above and below and the outer circumferential surface is restrained by the chip insertion hole 4, the inner circumferential surface of the spaghetti extrusion hole 1 bulges inward and deforms.

Therefore, the present invention aims to provide a method for manufacturing a spaghetti extrusion die in which the spaghetti extrusion hole is not deformed.

(Means for Solving the Problems) In order to solve the above problems, the method for manufacturing a spaghetti extrusion die of the present invention uses chips of polytetrafluoroethylene,
The chip is set in a holder that holds at least its outer circumferential surface, and then a spaghetti extrusion hole is drilled through the center of the chip, and then the chip having the spaghetti extrusion hole is inserted into the die body with the holder, which is pre-drilled. It is characterized by being pushed into the hole together with a chip holder.

(Function) As described above, in the method of manufacturing the spaghetti extrusion die of the present invention, the polytetrafluoroethylene chips are inserted together with the holder into the chip insertion hole of the die body by pushing them together with the chip holder, so the chips are inserted from the top and bottom. There is no compressive force, and therefore the inner circumferential surface of the spaghetti extrusion hole of the chip does not bulge inward.

(Example) An example of the method for manufacturing a spaghetti extrusion die according to the present invention will be described with reference to the drawings. As shown in FIG. As shown in Figure 1, which holds the peripheral edge and outer circumferential surface spanning one width on both edges (outer diameter 5 m, inner diameter 2.5 m, thickness 4.
Then, as shown in FIG. 10 with holder 11,
As shown in FIG. 1d, the die body 13 made of brass with a thickness of 3011 mm has 800 chip insertion holes 14 with a diameter of 5 mm drilled in advance, and an introduction hole 15 with an inner diameter of 2 mm and a taper angle of 6 mm.
Chip holder 1 made of brass and having a 0 degree guide hole 16
7 and insert it together with spaghetti extrusion die 1.
8 was manufactured.

On the other hand, as shown in Fig. 2a, a spaghetti extrusion hole 1 with a diameter of 5 mm and a thickness of 2 mm was pre-drilled in the center using a conventional method.
Chips 2 made of Tsuru's polytetrafluoroethylene were inserted into 800 chip insertion holes 4 with a diameter of 5I11 pre-drilled in a die body 3 made of brass with a thickness of 3 and Q mm, as shown in Fig. 2. Then, a die 8 for extruding spaghetti was manufactured by pressing and mounting together with a chip holder 7 made of brass having an introduction hole 5 with an inner diameter of 2 fins and a guide hole 6 with a 60 degree angle.

However, when the dimensions of the spaghetti extrusion holes 12.1 of the spaghetti extrusion dies 18.8 of the embodiment and the conventional example manufactured as described above were measured, the results were obtained as shown in the table below.

As is clear from the table above, the extrusion holes 1 of the spaghetti extrusion die 8 of the conventional example have a large number of hole deformations, and the hole diameters vary widely and are small, whereas the spaghetti extrusion die 18 of the embodiment The number of holes deformed in the extruded holes 12 was small, and the pore diameters had very little variation (and none were extremely small).

In the above embodiment, the polytetrafluoroethylene chip is placed in a holder that holds the peripheral edges and outer peripheral surface of both the upper and lower surfaces, but the present invention is not limited to this, and only the outer peripheral surface of the chip is inserted. A holder that holds the holder may also be used.

(Effects of the Invention) As can be seen from the above explanation, according to the method for manufacturing spaghetti extrusion dies of the present invention, polytetrafluoroethylene chips are inserted together with the holder by pushing them into the chip insertion hole of the die body together with the chip holder. Therefore, the chips are not subjected to compressive force from the vertical direction, and the inner peripheral surface of the extrusion hole for spaghetti in the chips does not bulge inward. Therefore, it is possible to extrude spaghetti with stable dimensions and shape. There is an effect that it can be done.
