Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a cutting blade roll for noodle making which cuts a sheet made of udon powder into an elongated shape in order to produce noodles such as udon and ramen.

[Conventional technology]

Conventionally, in order to mass-produce so-called noodles such as udon and ramen, a sheet made of udon powder is passed between two rotating cutting blade rolls as shown in FIG. 0.5 to 8 mm) is cut and manufactured. In this case, the positional relationship between the two cutting blade rolls is such that the annular protrusions (blade members) formed on the outer peripheral portion of each cutting blade roll partially intervene in the annular groove of the other cutting blade roll. By rotating the noodle-making sheet made of udon powder, the noodle-making sheet is sequentially cut.

[Problems of conventional technology]

However, as described above, since the cutting blade roll provided with the annular protruding portion and the annular groove alternately is generally made of iron, the cutting blade formed on the annular protruding portion is easily corroded by salt, and is easily worn and cut. Since the characteristics deteriorate after being used for about one week, it is necessary to replace it with a new one or polish it. Not only the labor and cost required for the work, but also the productivity due to the noodle making device being stopped. Was causing a decline.

For this reason, there is a stainless steel cutting blade roll in order to eliminate the generation of rust that deteriorates the cutting characteristics, but it cannot be said that it has good sharpness, and since the hardness is low, the degree of wear is large and the life is even shorter.

Furthermore, with the iron or stainless steel cutting blade roll, it is difficult to polish the annular protruding portion surface or annular groove surface on which the blade is formed into a mirror surface, even if it has been subjected to polishing finish. Also, because it has good wettability with water, noodle sheets made by kneading udon powder or noodles or powders obtained by cutting the sheet easily adhere to the noodle sheet, which often deteriorates the cutting characteristics and hinders the noodle making process. It was

[Means for solving problems]

In view of the above, the cutting blade roll and the spacer ring are made of a ceramic material such as alumina, zirconia, silicon carbide, and silicon nitride, which has excellent corrosion resistance and wear resistance.

〔Example〕

FIG. 1 shows a plan view in which cutting blade rolls 1 and 1 according to an embodiment of the present invention are combined in a mounted state. In this cutting blade roll 1, a plurality of annular protrusions 2 are arranged via annular grooves 3. Cage,
In FIG. 2, as shown in an enlarged partial view of the portion A in FIG. 1, both cutting blade rolls 1 and 1 are combined so that they rotate with the annular projection 2 slightly entering the mating annular groove 3. Has been used. That is, by rotating the pair of cutting blade rolls 1 and 1, the noodle-making sheet S can be cut by the shearing force caused by the sliding of the side surfaces of the opposed annular protrusions 2. The cutting blade roll 1 used in this way has a metallic shaft 4 as shown in the exploded view of FIG.
A fixed flange 4a is provided at one end of the
A plurality of ceramic discs 2a forming an annular protrusion 2 and a plurality of spacer rings 6 made of ceramic having a smaller diameter than the discs 2a are alternately laminated and fastened with a nut 7 at the other end. In this case, in order to absorb the thermal expansion of the shaft 4, it is advisable to interpose a elastic member such as a washer or a rubber plate between the nut 7 and the spacer 6.

A blade 2b is formed on the edge portion of the annular protrusion 2 which is the outer peripheral portion of the ceramic disc 2a shown in FIG. 2, and the blade angle θ ₁ is about 90 degrees or slightly smaller. The noodle making sheet S shown by the dotted line in the figure has a long shape in an angled state by combining the blades having such a blade angle as shown in FIG. It is cut into pieces and made into udon, xymen, etc.

Further, in order to construct a cutting blade roll for making noodles such as noodles having a polygonal cross-section as noodles, dried noodles, etc., as shown in FIG.
3 as peak angle theta ₂ to the annular protrusion 20 located at the outer peripheral portion of the
Noodle making sheet S shown by a dotted line in the figure by forming blades of 0 to 70 degrees and arranging blades having such angles to rotate so that their blade surfaces face each other. Noodles such as somen with a polygonal cross-sectional shape are produced.

By the way, the ceramic disk 2 that constitutes the cutting edge as described above
Ceramic materials such as alumina, zirconia, silicon carbide, and silicon nitride, which have high hardness, high wear resistance, and high corrosion resistance, are suitable materials for the a and 20a and the spacer ring 6.

〔The invention's effect〕

As described above, the cutting blade roll for noodle making of the present invention is such that a ceramic disk provided with a blade and a ceramic spacer ring for setting the ceramic disk at a predetermined interval are alternately inserted on the outer periphery of the shaft. However, since it is integrated by tightening with a nut, the blade of the disc and the outer peripheral surface of the spacer ring do not rust or corrode, and since it has excellent wear resistance, the disc is a conventional iron cutting blade roll. The life is 20 times longer than that of the above, and the noodle making machine will not be stopped more than necessary for replacing the disc or the spacer ring. In addition, since there is no adhesion of noodles or powder to the disk or spacer ring, there is no risk of forming irregularly shaped noodles, and further, the disk is subject to blade cutting or blade spillage, or the outer peripheral surface of the spacer ring is roughened. Even if occurs, remove the tightening nut, it is possible to maintain good cutting characteristics for a long period of time by replacing only the defective disk or spacer ring, such as the noodle cutting blade roll of the present invention According to the above, it is possible to provide an excellent noodle making machine, and thus an excellent quality noodle product.
