Abstract

PURPOSE:To prepare bread crumb directly from the raw material with remarkably simplified procedure, by bundling a number of expanded strings made of specific material such as wheat flour, stretching the bundle to obtain a fibrous material having longitudinal slits, and drying and cutting the material. CONSTITUTION:The material made of wheat flour etc. kneaded with the screw 2 in the cylinder 1 of an extruder is extruded through the perforated plate 4 attached to the extruding end 3 and having a number of perforations 4a with the total area of A1, and then expanded by extruding through the die 5 having a contracted opening area A2 with a draw ratio (A1/A2) of >=1. A number of expanded strings having a number of small cavities generated by the expansion process are bundled, pressed and drawn by stretching with the first roller 6a having longitudinal slits at a rate higher than the delivered speed of the expanded material, dried by the drier 8, stretched with the second roller 6b in a manner similar to the above, pressed to obtain a fibrous material having longitudinal slits, dried by the drier 9, and cut with the cutter 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and apparatus for directly producing bread crumbs from raw materials such as wheat flour.

(Prior art) Conventionally, when producing bread crumbs, fibrous bread is first baked, then this bread is sliced along the fiber direction, and then the sliced bread is heated by 10+W in the direction perpendicular to the fiber direction. It was manufactured by cutting it to certain lengths.

[Problems to be solved]

In the past, bread was made once and then cut into small pieces to produce bread crumbs, which had the problem of requiring numerous steps and time to produce bread crumbs from raw materials such as wheat flour. Was.

[Means for solving problems]

The present invention was made in view of the above-mentioned drawbacks, and is made by extruding a material such as wheat flour into a large number of strings and swelling them, and then bundling and stretching the swollen large number of string-shaped materials to create a vertical grain as a whole. Bread crumbs are produced by drying this fibrous material and then cutting the fibrous material into predetermined lengths. Further, an apparatus for carrying out this method for producing bread crumbs includes an extrusion section comprising a perforated plate having a large number of small holes and a die that expands the string-like material extruded from the perforated plate;
A roller device that bundles and stretches the string-like material extruded from this extrusion section to make a fibrous material with vertical grain as a whole, and a cutter that cuts the fibrous material to a predetermined length to make bread crumbs. It is composed. As a result, bread crumbs can be directly produced from raw materials such as wheat flour, and the bread crumb manufacturing process can be significantly simplified compared to conventional means.

(Example〕 Next, examples of the present invention will be described.

First, an embodiment of a bread crumb manufacturing apparatus will be described based on the drawings. In these figures, 1 is the cylinder of the extruder and 2 is the screw. The cylinder 1 and the screw 2 knead flour, which is a material for bread crumbs. Reference numeral 3 denotes an extrusion unit attached to the tip of the cylinder 1, which has a large number of small holes 4a, and includes a perforated plate 4 through which the material is extruded in the form of a string, and a large number of materials extruded from the perforated plate 4. and a die 5 for bundling and expanding the string-like material. In this case, the extrusion side cross-sectional area A2 of the die 5 is equal to or smaller than the total cross-sectional area AI of the small holes 4a in the perforated plate 4. In other words, the drawing ratio of die 5 (AI/A,
) is 1 or more, preferably L5 or more, to promote swelling of the material.

Reference numeral 6 denotes a roller device, which includes a 10th roller 6a that bundles and presses a large number of expanded materials extruded from the extrusion section 3 of the extruder and stretches them, and a 10th roller 6a that stretches the materials stretched by the first roller 6a. It consists of a 20th roller 6b for stretching.

Therefore, the 10th roller 6a pulls the material at a faster rate than the flow rate of the material extruded from the extrusion section 3, and the 10th
The respective rotational speeds of the 0-ra 6b are selected to pull the material at a faster rate than the 1-T:1-ra 6a.

In addition, the shapes of the first roller 6a and the second CI roller 6b include those with blades as shown in FIGS. 3a and 3b in order to make slits in the vertical direction of the material, or those with blades in the horizontal direction of the material. A blade as shown in FIG. 3C may be provided to make the slit. Furthermore, it is also possible to use these in combination.

Note that the roller in the roller device 6 is the first roller 6a.
The present invention is not limited to a two-stage type consisting of a 20th-ra and a 20th-ra 6b, but may be a multi-stage type with a 30th-ra, a 40th-ra, etc. attached thereto.

Reference numeral 7 denotes a cutter provided after the roller device 6, which moves up and down and cuts the material sent from the 20th roller 6b to form bread crumbs. As the cutter 7, various types can be used, such as a guillotine cutter and a rotary cutter. 8 and 9
is a drying device, and the first drying device 8 includes the first CI-968 and M
2a-'yeb.

The second drying device 9Fi and the second CI-26 are placed in between.
It is placed between the cutter 7 and the cutter 7. Normally, the l/C1 drying device 8 dries the material to a degree suitable for stretching the material and in preparation for drying in the next step. Further, in the second drying device 9, the material is dried to the extent that the cutter 7 can cut the material into bread crumbs.

The location and number of drying devices are not limited to those in the embodiments, and can be changed as appropriate depending on manufacturing conditions.

In addition to forced drying using a drying device, it is also possible to perform natural drying depending on the case.

Next, a method for producing bread crumbs using the apparatus of the above embodiment will be explained.

A material made of wheat flour or the like kneaded in an extruder is extruded as a large number of string-like materials from a perforated plate 4 of an extrusion section 3, and these many string-like materials are extruded through a die 5 with a narrowed opening cross section and expanded. This swelling creates many small cavities within the material. The expanded material is then pulled by the first roller 6a of the roller arrangement 6. Therefore, a large number of swollen string-like materials are bundled and pressed and stretched at this point, so that the hollow portions generated in the materials are also stretched thinly in the longitudinal direction to form vertical grains. Furthermore, the material from the 10th layer 6a is stretched and pressed by the 20th layer 6b to form a fibrous material with elongated longitudinal grains. Then, this fibrous material is dried and cut with a cutter 7 to produce bread crumbs.

Note that when the material is stretched by the roller device 6 to form an Al or string-like material, if a slit is made in the material, it can be dried quickly and the material can be easily cut with a cutter.

〔Effect of the invention〕

According to the present invention as described above, when producing bread crumbs,
Since bread crumbs can be produced directly from the ingredients without having to make bread once, the process for producing bread crumbs can be significantly simplified.
