Description

  The present invention relates to a noodle making apparatus, and more particularly to a noodle making apparatus in which kneaded raw materials are extruded from a nozzle having a through-hole using a screw to obtain noodles.

  Soba noodles and udon noodle foods are obtained by adding water and binders to the ingredients such as buckwheat flour and wheat flour and kneading them, and then forming them into a slender string shape. In recent years, a gourmet boom and a return to slow food have been proposed, and so-called “hand-made” noodles are considered valuable.

  The “hand-made” noodles are made by manually kneading the material powder and extending it to the required thickness, for example, “Tenobebe noodles”, or extending it thinly like a buckwheat noodle and cutting it into thin pieces using a knife. Is.

  On the other hand, various apparatuses have been put into practical use for the purpose of providing noodles at low cost by mass-producing them. In this case, a general mixing and kneading apparatus is used for kneading, and for noodle making, a roll extruder or the like is used to extend thinly, and it is cut into thin pieces with a comb-tooth cutter or the like. For example, a method of extruding from a nozzle to make noodles is used.

  However, in the noodle making process using an extruder, starch contained in the raw material may become α without being able to control the temperature rise caused by the friction with the apparatus when extruding the raw material and the shearing force applied to the raw material. The problem is unavoidable. Also, the extruder is usually made of metal, and in some cases, the friction between the screw and the inner wall of the casing in which the screw is housed may cause the metal constituting the device to be scraped and mixed into the noodles. Absent.

  When metal pieces are mixed into noodles, they may damage the oral cavity and the like, and may be ionized and absorbed in the digestive tract and act as a chronic poison on the human body. This can be dealt with to a considerable extent by increasing the gap between the screw and the casing. However, in this case, the amount of extrusion per unit time decreases, which hinders productivity. Arise.

  On the other hand, polymer materials are generally not digested even when ingested with food, and have little effect on the human body. Therefore, the surface of the screw and the inner wall of the casing are made like Teflon (registered trademark). It may be dealt with by coating with a fluorine-based polymer material.

  Various types of noodle making apparatuses to which an extruder is applied have been put to practical use. For example, Patent Document 1 and Patent Document 2 disclose noodle making apparatuses and noodle making machines that can easily clean each part of the apparatus. Has been. However, what is disclosed in these is related to the improvement of maintenance workability as described above, and it is the actual situation that no problem has been found in dealing with the problems caused by the metal constituting the apparatus.

  Accordingly, an object of the present invention is to make it possible to control the temperature rise during extrusion in a noodle making apparatus using an extruder, and to solve the problem due to metal wear.

  In the present invention, the polymer material is flexible compared to metal, deforms due to the load of external force, has low frictional resistance and little heat generation, and has little influence on the human body even if ingested. This has been made as a result of studying a structure in which the casing for housing the screw is made of a polymer material and the casing is not broken even by a high pressure applied in the extrusion process.

  That is, the present invention includes an extrusion screw, a casing having a tubular space for accommodating the extrusion screw, and an opening for supplying material formed on a side surface, and a casing covering at least a part of the casing. An adapter, a disk-shaped nozzle provided on the opening side of the front end side of the extrusion screw in the casing and having a plurality of through holes, and a screwing means for the casing adapter, the nozzle being the casing adapter In the noodle making apparatus having a nut fixed to the noodle making apparatus, the casing is made of a polymer material, and the casing adapter is made of a metal material.

  In the noodle making apparatus according to the present invention, the portion of the casing in which the screw is accommodated is made of a polymer material, so that there is little increase in temperature due to friction, and there is no metal piece generated by abrasion. It does not mix with noodles. Therefore, the change in the texture of the noodles due to the temperature rise and the influence on the human body can be eliminated.

  The polymer material that can be used in the present invention is not particularly limited as long as it has a certain level of mechanical strength, and includes so-called engineer plastics. Specific examples include polyacetal, MC nylon, and ultrahigh molecular weight polyethylene.

  Next, the form for implementing this invention is demonstrated. FIG. 1 is a perspective view showing an example of a noodle making apparatus according to an embodiment of the present invention. Moreover, FIG. 2 is sectional drawing of the part of the casing in the noodle making apparatus which concerns on embodiment of this invention.

  1 and 2, 1 is a housing, 2 is an octagon nut, 3 is a casing, 4 is a raw material charging adapter, 5 is a coupling, 6 is a casing adapter, 7 is a nozzle, 8 is a screw, 9 is a bearing, 10 Is a washer, 11 is a thrust bearing, 12 is a screw guide, and 13 is a C-type retaining ring.

  The screw 8 in this example has a flight outer diameter of 60 mm and is made of stainless steel. The casing 3 is manufactured by cutting polyacetal, and the casing adapter 6 is made of stainless steel.

  The nozzle 7 is a stainless steel disc having a thickness of about 12 mm, and is provided with a plurality of through holes having a diameter of 1 to 5 mm according to the required thickness of the noodles to be produced. The nozzle 7 is fixed by a female screw provided on the octagon nut 2 and a male screw provided on the casing adapter 6.

  Then, the raw materials separately kneaded are supplied from the charging adapter 4, and the drive motor (not shown) connected to the screw 8 through the coupling 5 is moved so that the raw materials are provided from the nozzle 7 to the nozzle 7. The noodles are obtained by extruding at approximately the same thickness as the inner diameter of the through-holes.

  Moreover, FIG. 3 is a figure which shows the state of the temperature rise of the raw material extruded by the noodle making apparatus of this Embodiment. In FIG. 3, the plots indicated by ◯ are for the noodle making apparatus of the present embodiment, and the plots for Δ are for the separately prepared metal casing noodle making apparatus.

  As apparent from FIG. 3, the noodle making apparatus according to the present invention generates less heat when extruding the raw material, and can reduce the influence on the taste and texture of the resulting noodles. As described above, according to the present invention, it is possible to provide a noodle making apparatus capable of producing noodles free from the influence of metal contamination and heat history in the production process.

  The present invention is not limited to the above-described embodiment, and can be conceived by those who have ordinary knowledge in the field of the present invention. For example, various types of materials such as a material other than polyacetal are adopted for the casing. Needless to say, even if there is a design change within a scope that does not depart from the gist including deformation and modification, it is included in the present invention.
