Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a surface having various mouth-

More particularly, the present invention relates to a method of manufacturing a noodle, and more particularly, to a method of manufacturing a noodle, which can feel various mouthfeel by a single process and at the same time, To a molded surface and to a molded injection surface.

Noodles are one of the most popular foods in Korea. According to the food category classification of noodles in Korea, noodles are divided into noodles, cold noodles, and noodles according to the raw materials. When the noodles are fried, pasta such as hot noodles, macaroni, spaghetti, Respectively.

On the other hand, in the case of the noodle, a surface cut by using a cutter after rolling the grain dough into rollers according to a manufacturing method is referred to as a cut surface, and a surface formed by passing through an extruder such as a screw and barrel is called an injection surface. Since the cut surface in which the kneaded material or the like is moved horizontally while being conveyed with the conveyor belt forms a wave in a zigzag manner in the traveling direction of the surface for compact packaging, it is difficult to form a wider surface over a certain level. On the other hand, the dried injection surface dried by the surface line passed through the high-temperature injection machine has a denser structure and a higher density than the porous liquid side. Particularly, since the injection surface adopts the nip surface method of pushing in the vertical direction by using the pressure of the screw, the width of the surface can be variously widened. For example, lasagna among the commonly consumed pastas in the West often exceeds 100 mm in width.

However, when the width of the surface line is widened, there arises a problem that the surface line sticks due to the contact between the injection lines formed in the adjacent injection die. As a result, inconvenience may arise in that the surface of the cooked meat must be constantly passed through during cooking. In particular, the noodles produced so far have to have the same thickness in the same process. Depending on the taste of the person who nourishes the noodles, there may be cases where a chewy texture is preferred or a soft texture is preferred. Also, when preparing the same noodles, a variety of mouthfeel may be desired. However, the noodles produced so far have been limited in meeting these demands.

Korean Patent Publication No. 10-2015-0059670

It is another object of the present invention to provide a method of manufacturing a surface which can facilitate convenience in cooking by preventing adhesion between adjacent surface lines and a molded injection surface.

Other objects and advantages of the present invention will become more apparent through the following detailed description of the invention and the appended claims.

The present invention having the above-mentioned object is directed to a molded exit surface having different thicknesses according to the area of the same surface line and, if necessary, a wave is formed in at least a part of the area, and a method of manufacturing such an exit surface.

That is, according to one aspect of the present invention, there is provided a method for producing a kneaded product, comprising the steps of: kneading and aging a blend of blended water to a prepared face material in a first extruder; A step of forming the surface of the kneaded product by passing the kneaded product through a second extruder, wherein when the kneaded product is molded in the second extruder, the product of the die hole Molding the surface so that the thickness of the surface line formed through the first region and the thickness of the surface line formed through the second region of the die hole are different from each other; And drying the molded surface.

In an exemplary embodiment, the penetrating portion that communicates the region into which the enriched kneaded matter of the second extruder is introduced and the region into which the molded surface of the second extruder is injected is formed to have an inclined portion .

Further, in one exemplary embodiment, a surface formed through the first area of the die holes may be shaped to have a continuous wave shape (wrinkle shape) along the emission direction.

For example, the overall width of the surface line formed through the second extruder may range from 5 to 20 mm.

The step of obtaining the enriched kneaded product may include kneading and enriching 100 parts by weight of the face material and 33 to 37 parts by weight of the compounding agent in the first extruder.

The inventors of the present invention have completed the present invention in view of the fact that a surface capable of realizing various mouth-feel can be manufactured through a simple process in an injection process. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings where necessary.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view of a process for producing a surface enabling various mouthfeelings, in accordance with an exemplary embodiment of the present invention. Fig. As shown in Fig. 1, the surface to be molded according to the present invention includes a step of mixing a compounding ingredient, which is a surface material, into the compounding water; Kneading / mixing the mixed compound in a first extruder (100) to obtain a kneaded product; A step of forming a face line having a different thickness (thickness) by passing the kneaded water through the second injector (200); For example, the drying process may be divided into a pre-drying process 300 and a main drying process 400, and the packaging process 500. This will be described in more detail.

[Cotton material mixing process]

First, prepare the prepared cotton material. The face produced according to the present invention may be an instant dry noodle such as a cold face, a slippery face, a facial face or the like as an injection face. In the exemplary embodiment, wheat flour, starch (e.g., sweet potato starch, potato starch and / or tapioca starch) and buckwheat flour are used as a cotton material when the noodle to be produced is a cold noodle, And starch in the case of the immediate face, respectively, as main ingredients of the cotton material.

For example, the face material may be in the form of a blend containing flour as a main ingredient and, if necessary, other ingredients. In one exemplary and alternative embodiment, the cotton material is selected from the group consisting of rice flour, wheat flour, barley flour, buckwheat flour, corn flour, millet flour, coarse meal, oat flour, mung bean flour, millet flour, And the like.

In another alternative embodiment, the face material may be a blend of blend of a plurality of materials. For example, the cotton material may comprise 70 to 90 parts by weight of rice flour; 5 to 20 parts by weight of potato starch; 5-25 parts by weight of buckwheat flour, barley flour or acorn powder; And 0.2 to 3 parts by weight of powdered fibrin. The term " part by weight " as used herein is understood to mean the relative weight ratio between the components making up any mixture or composition, unless otherwise stated. Basically, since elasticity is imparted to the surface line through an injection process to be described later, a unique chewy texture can be imparted, and at the same time, a smooth texture can be imparted through the surface lines having different thicknesses.

[Dough and Grading Process by First Injector]

The compounding of the mixture of the cotton material and the compounding water described above is applied to a first injector 100 capable of functioning as a kneading machine, and a dough and a glazing process are carried out.

0.5 to 5 parts by weight of purified salt, 0.5 to 2 parts by weight of seaweed extract, 0.5 to 5 parts by weight of a rice bran flavor and about 21 to 35.5 parts by weight of a rice bran flavor are mixed with 100 parts by weight of a cotton material By weight of purified water.

Using kelp extract, starch elution can be controlled appropriately when cotton materials with a high starch elution, such as rice flour, are used. If the content of the sea tangle extract constituting the compounding water is less than 0.5 part by weight with respect to 100 parts by weight of the cotton material, the effect of controlling the starch elution of the finally produced injection surface may be insufficient. If the content is more than 2 parts by weight, The texture of the food is too hard and the surface is smooth, so that there is a fear that the texture is lowered.

It is preferable that the total number of components is 20 to 50 parts by weight, preferably 33 to 37 parts by weight based on 100 parts by weight of the cotton material. If the content of the blended water is less than 33 parts by weight with respect to 100 parts by weight of the cotton material, the finally prepared injection face may be excessively expanded and the starch elution may become worse. If the content of the blended water exceeds 37 parts by weight, 100 and / or inside the second injector 200, it may become difficult to transfer the dough mass.

In one exemplary embodiment, when performing a dough and a glazing process in the first injector 100, the dough may be glazed by applying heat at 60 to 120 캜, preferably 100 to 120 캜, simultaneously with the dough . In general, the time during which the dough and the gelatinization are performed through the first injector 100 may take place in a short time of 20 to 40 seconds. The degree of liquefaction can be enhanced to 70 to 95% by the dough and the liquefaction process in the first injector 100.

In one exemplary embodiment, when the kneading of the flour and the compounding water is enhanced, the water content in the kneaded kneaded water is 27 to 33%, and the transferability and processability in the later-described second extruder 200 and the like are good . Further, in the exemplary embodiment of the present invention, the kneading and sizing of the blend can be carried out simultaneously in the first injector 100, and the degree of gelatinization of the dough is 70 to 95%, so that the glazed flakes do not stick to each other.

[Step of forming surface line by the second injector]

The kneading mass obtained by the kneading and glazing process in the first injector 100 is formed with a surface line having an appropriate size of the face width and the face thickness through the injection process in the second injector 200. According to the present invention, the thickness of one face line varies according to the region according to the injection process in the second injector 200, so that a chewy texture and a soft texture can be felt at the same time, and the width of the face line is relatively wide, It is possible to prevent the attachment of the adjacent surfaces to each other, and to form a surface line that can provide convenience during cooking. This will be described with reference to the accompanying drawings.

2 is a perspective view schematically showing an injection die constituting a second injector in which a glazed surface is injected according to an exemplary embodiment of the present invention. 3 is a cross-sectional view taken along the line III-III 'of FIG. 4A and 4B are schematic views showing a die hole of an entrance portion and a die hole of an exit portion of the injection die, respectively. As shown in the drawing, the injection die 210 constituting the second injector 200 (see FIG. 1) includes an entrance 220 into which the kneaded mass formed by the first injector 100 (see FIG. 1) enters, A discharge part 230 formed in an area opposite to the part 220 and formed in the form of a surface line having a predetermined thickness and width and a discharge part 210 through a supply part 221 of the entrance part 220, And a penetration part 240 communicating the entrance part 220 and the discharge part 230 so that the lump of the dough that has flowed into the inside of the cavity 220 can be formed through the discharge part 230.

When the shape of the die passes through the area from the entry area of the kneaded product to the exit area, when the powdered granular material is kneaded and kneaded and then passed through the die of the second injection machine, So that they have different thicknesses. For example, a pair of supply parts 221 for supplying the kneaded and agglomerated dough masses to the injection die 210 through the first injector 100 are formed in the entrance part 220, A pair of die holes 231 for forming a dough mass introduced into the injection die 210 into a predetermined thickness and width are formed. However, the number of the supply part 221 and the die hole 231 formed in the entrance part 220 and the discharge part 230, respectively, may be adjusted as necessary.

The supply part 221 formed in the entrance part 221 is provided to be able to supply the dough mass into the injection die 210 constituting the second injector 200, 230). In one exemplary embodiment, the supply portion 221 formed in the entry portion 220 may be formed wider than the die hole 231 formed in the discharge portion 230.

For example, in the drawing, the supply unit 221 includes a first region supply unit 222 having a generally long rod-shaped planar shape, a second region supply unit 222 having a second planar shape having a larger area than the first region supply unit 222, And a region supply unit 224. The shape of the supply part 221 shown in the drawing is exemplary and may be any shape as long as it has a wider shape than the die hole 231 described later. In an alternative embodiment, the first region supply section 222 may have a relatively large circular shape, and the second region supply section 224 may have a rod shape smaller than this. Alternatively, the first region supply unit 222 and the second region supply unit 224 may both have a rod shape or a circular shape.

The die hole 231 of the discharge part 230 communicated with the supply part 221 formed in the entrance part 220 and the penetration part 240 may be composed of two areas having different thicknesses . For example, the die hole 231 of the discharge portion 230 communicated with the supply portion 231 of the entry portion 220 includes a first area die hole 232 having a first thickness T1, And a second area die hole 234 having a thickness T2.

In one exemplary embodiment, the first thickness T1 may be greater than the second thickness T2. For example, the first thickness T1 of the first area die hole 232 may be in the range of 1.5 to 3.0 mm, and the second thickness T2 of the second area die hole 234 may be in the range of 0.5 to 1.0 mm Lt; / RTI > In another alternative embodiment, the first thickness T1 may be smaller than the second thickness T2.

The surfaces formed through the die holes 231 constituting the discharge portion 230 of the injection die 210 constituting the second injector 200 are not the same in thickness And have different thicknesses. That is, the thickness of the surface line passing through the first area die hole 232 in the die hole 231 of the discharging portion 230 becomes larger than the thickness of the surface line passing through the second area die hole 234. Is shown in Figure 5, which is a perspective view schematically illustrating a molded surface line 600 in accordance with an exemplary embodiment of the present invention. The thickness T1 of the surface line 610 that has passed through the relatively thick first area 231 of the die hole 231 constituting the discharge portion 230 and the thickness T1 of the die hole 232 of the discharge portion 230 The thickness T2 of the surface line 620 passing through the thin second region 232 is different.

As described above, according to the present invention, the thickness of the surface line formed through the first area die hole 232 and the second area die hole 234 in the die hole 231 of the discharge part 230 is different from each other. Therefore, in the case of cooking using the finally produced surface according to the present invention, a soft texture (a surface having passed through a thin thickness region) and a chewy texture (a surface having passed a wide thickness region) are simultaneously felt through the same cooking time .

On the other hand, according to the present invention, the overall width W of the die holes 231 and 232, in which a surface is relatively formed as compared with a conventional injection surface, can be increased to provide a sufficient texture have. In one exemplary embodiment, the width W of the die hole 231 may range from 5 to 20 mm. As a result, the width W of the surface line passing through the die hole 231 becomes relatively wider. The surface area due to the increased width W of the surface line formed in the second injector 200 increases, so that the adjacent surface lines can be attached to each other. Adherence to adjacent lines can cause discomfort because they must be whipped constantly during the cooking process.

In order to prevent this, the surface to be injected may be guided so as to have a wave shape (wrinkle shape). As one exemplary method for forming wrinkles on the exit surface, a method may be considered to reduce the rate at which the dough is molded and injected relative to the rate at which the dough is introduced into the injection die 210. The area of the supply part 221 constituting the entrance part 220 into which the kneaded product flows may be formed larger than the area of the die hole 231 constituting the discharge part 230 have.

Further, in one exemplary embodiment, the penetration portion 240 communicating between the entry portion 220 where the kneaded product enters the injection die 210 and the discharge portion 230 formed by the kneaded product is formed into a shape There may be a way to change at least a portion of its shape, rather than a full cylindrical shape. For example, the shape of the penetrating portion 240 allows a large amount of the kneaded water to flow into the relatively large area of the entering portion 220, and the relatively small area of the discharging portion 230 So that a relatively small amount of surface line can be injected. For this, an inclined portion 242 is formed in the region of the penetration portion 240 near the discharge portion 230 in the figure.

In one exemplary embodiment, the slope portion 242 includes a second region supply portion 224 having a relatively large area among the supply portions 221 constituting the entrance portion 220, Holes 234 in the vicinity of the second area die holes 234 constituting the discharging part 230 among the penetrating parts 240 communicating with the second area die holes 234 having a relatively small thickness T2 in the die holes 231 Respectively. The first area supply part 222 having a relatively small area in the supply part 221 and the first area die hole 232 having a relatively large thickness T1 among the die holes 231, (240) may not form such an inclined portion.

In the drawing, for example, a second region supply portion 224 having a relatively large area in the supply portion 221 and a second region die hole 234 having a relatively small thickness T2 among the die holes 231 The inclined portion 242 is formed only in the region adjacent to the discharge portion 230 of the penetrating portion 240 which is formed in the through hole 240. Alternatively, for example, a first area supply part 222 having a relatively small area in the supply part 221 and a first area die hole 232 having a relatively large thickness T1 in the die hole 231 The inclined portion may be formed only in a region adjacent to the discharge portion 230 of the penetrating portion 240 communicating therewith.

The inclined portion of the penetrating portion 240 is formed to have a relatively large thickness T1 between the first region supply portion 222 and the die hole 231 having a relatively small area among the supply portions 221. In other embodiments, A second region supply portion 224 having a relatively large area of the supply portion 221 and a die hole 231 having a relatively small thickness T2 between the die hole 231 and the first region die hole 232, Both of the through holes communicating with the two-region die holes 234 may be formed in a region adjacent to the discharge portion.

A case where the inclined portion 242 is formed in the region of the discharging portion 230 of the penetrating portion 240 that communicates the second region supply hole 224 and the second area die hole 234 Explain. In this case, the amount of the dough to be introduced from the first region supply unit 222 having a relatively narrow area in the supply unit 221 and the amount of the dough to be introduced into the first area die hole 232 The amount of the kneaded water discharged is not greatly different. In other words, the inflow amount and the discharge amount of the kneaded product in the first area die hole 232 are not greatly different from each other. Therefore, the inflow pressure and the discharge pressure of the kneaded product in the first area die hole 232 having a relatively large thickness T1 in the die hole 231 in which the surface is formed are substantially the same.

On the other hand, a large amount of the kneading water is introduced through the second region supply unit 224 having a relatively large area in the supply unit 221. Since the inclined portion 242 is formed before the kneaded product is injected through the die hole second region 234 having the relatively small thickness T2 in the die hole 231 constituting the discharge portion 230, Area is smaller than that of the second region supply unit 224. [ In the die hole second region 234 where the passage area of the kneaded product becomes narrow due to the inclined portion 242 compared to the relatively wide kneaded water passage area of the second region supply portion 224 into which a large amount of kneading water is introduced In order to discharge the relatively large amount of the kneaded water, the discharge pressure is inevitably increased. In other words, in the second area die hole 234 having a relatively small thickness T2 in the die hole 231, the discharge pressure of the paste is considerably larger than the inflow pressure of the paste.

As a result, the discharge pressure in the die-hole first region 232 having a relatively large thickness T1 does not have a large difference from the inflow pressure, whereas the die-hole second region 234 having a relatively small thickness T2 ) Are different from the inflow pressure. The pressure in the die hole second region 234 having a relatively small thickness T2 is much larger than the pressure in the die hole first region 232 having a relatively large thickness T1. When a difference in discharge pressure occurs between the first region 232 and the second region 234 constituting one die hole 231, the pressure is dispersed in the first region 232 having a low discharge pressure, In this process, a continuous wave shape (wrinkle shape) can be formed in the longitudinal direction of the surface line passing through the die-hole first region 232 having a low discharge pressure.

As described above, when the inclined portion 242 is formed in the vicinity of the die-hole second region 234 in accordance with the exemplary embodiment of the present invention, an excessive discharge pressure is applied to the die-hole second region 234, Hole first region 232 having a relatively small discharge pressure. Therefore, of the formed surface line 600 (see FIG. 5) according to the exemplary embodiment of the present invention, the surface line 610 passing through the first region 232 having a relatively thick thickness T1 in the die hole 231, A continuous wave shape 612 is formed along the longitudinal direction of the surface line and the surface line 620 passing through the second region 234 having a relatively thin thickness T2 in the die hole 231 is substantially a wave shape And is ejected in a flat shape without a gap.

In the drawing, a dotted line is formed in which a wave shape is formed on the surface line of the area passing through the second area die hole 234 having the second thickness T2 in the die hole 231 as an example. However, depending on the configuration of the inclined portion, a wave shape may be formed on the surface line corresponding to the area passing through the first area die hole 232 having the first thickness T1 in the die hole 231, A wave shape may be formed on the surface line corresponding to all the areas passing through the hole 232 and the second area die hole 234. [

According to the exemplary embodiment of the present invention, when a continuous wave shape is formed along the emission direction, the attachment area of adjacent surface lines is greatly reduced. Therefore, according to the present invention, it is possible to form a surface line which can provide convenience in cooking while preventing the adhesion of adjacent surface lines while allowing the surface line to have a relatively wide width, thereby enabling a sufficient texture.

In one exemplary embodiment, the process of forming a face line by the second injector 200 can be performed for a short time of several seconds, for example, 2 to 10 seconds. Therefore, even if the operating temperature of the second injector 200 is set to be in the range of 30 to 50 ° C, it is possible to control the temperature of the first extruder 100 at a relatively high temperature condition (for example, 60 to 120 ° C) The temperature is not cooled to the set temperature of the second extruder.

Particularly, according to the present invention, since the width W of the die hole 231 constituting the injection die 210 of the second injector 200 is relatively large, the surface area of the formed surface line is large, And some regions have continuous wave shapes 622 along the injection direction. As described above, the surface area of the surface line irradiated from the second injector 200 still operating at a high temperature condition is wide, and a wave for preventing the adhesion of the adjacent surface lines is formed, so that the amount of moisture separated from the surface line decreases. Therefore, during the transfer to the drying step described later, the step of drying the surface of the surface line is not necessary in order to eliminate the phenomenon of sticking to each other as in the conventional art.

[Cutting and Forming Process]

Although not shown separately in the drawings, the thickness of the second injection machine 200 is different according to the area of the same surface line, and the surface line formed in the longitudinal direction of the surface line in at least a part of the surface line is cut Can be carried out. Illustratively, the surface line formed through the second injector 200 is provided with an air knife on the front and rear sides so as to suppress the adhesion of the cut surface, spraying hot air, and cutting the surface line into a predetermined size in the longitudinal direction . In one exemplary embodiment, the entire length of the face line can be cut and shaped to a size of approximately 200 to 600 mm, preferably 200 to 400 mm.

In one exemplary embodiment, the lower end Air injection may be performed two times over the dry seated faces in individualized weight units. It is possible to adjust the shape of the surface to be rounded by distributing the surface line gathered at the center of the dried pellet through the instantaneous air injection and to maximize the gap between the surface lines through the second rotary air injection. If necessary, primary air injection may be omitted.

[Drying step]

According to an exemplary embodiment of the present invention, a process of drying a surface line having a different thickness in the second injector 200 and having a continuous wave shape in at least a part of the region includes a preliminary drying process 300 and a main drying process 400, .

For example, the preliminary drying step 300 may be performed at a temperature of 65 to 75 ° C so as to prevent the molded surfaces from being clumped by adjusting the air injection pressure so that the injection surfaces formed through the second injector 200 are evenly dispersed, And a relative humidity of 10 to 30% for 3 to 5 minutes. If the drying temperature is less than 65 ° C in the preliminary drying process, the drying may not be carried out to cause lumps of the surface during the preservation period. If the drying temperature exceeds 75 ° C, cracks may occur in the surface line,

Meanwhile, the present drying step 400 is performed, for example, by drying at a temperature of 40 to 60 DEG C and a relative humidity of 30 to 40% for 40 to 80 minutes and cooling to room temperature by a cold wind. If the drying temperature is less than 45 ° C in this drying step (400), drying is not performed and molds are generated on the injection surface during the preservation period. If the drying temperature exceeds 60 ° C, color change of the emission surface, that is, browning occurs.

According to the exemplary embodiment of the present invention, the following advantages can be obtained when the relative humidity is controlled in the drying process and the preliminary drying process is relatively high temperature and the main drying process is relatively low temperature. If the drying on the molded surface is too fast, the surface that comes into contact with the wind is first dried and hardened, so that the internal drying is delayed, the shape is bent, the internal stress is twisted and broken during drying, To control the rate of drying in order to prevent them.

Particularly, when the surface of the surface line is dried, a moisture difference with the inside is generated, and then the inside water moves to the surface. If the movement of the inside water to the surface is slower than the surface drying, Lt; / RTI > Therefore, it is important to reduce the evaporation from the surface and to achieve the diffusion effect from the inside.

Therefore, if the drying is performed at a relatively high temperature and a relatively high temperature, as described above, the inner moisture can be moved to the surface first and the shape of the surface can be maintained while maximizing the pore space. In addition, by lowering the temperature and increasing the relative humidity, the drying speed at the surface of the surface is minimized by secondary drying, thereby maintaining the internal moisture diffusion and the speed, thereby making it possible to produce a dense and transparent injection-molded surface.

Hereinafter, the present invention will be described in detail with reference to exemplary embodiments. However, the present invention is not limited to the invention described in the following examples.

100 parts by weight of a blend containing flour such as rice flour as a cotton material was added to a first extruder corresponding to a kneader, and 35 parts by weight of blended water was added to 100 parts by weight of the blend. To the mixture water, 1 part by weight of purified salt, 1.2 parts by weight of seaweed extract, 3 parts by weight of rice bran flavor and a residual amount of water were mixed with 100 parts by weight of cotton material. The compounding ingredients as the cotton material and the compounding water were put into a kneader and kneaded and gelled at 110 DEG C for 30 seconds. The mass of the kneaded dough was cut to a predetermined weight and transferred to a second extruder by air shift. The width of the die hole constituting the second injection machine for molding was set to 7 mm and the thickness of the die hole of the cut surface was 0.7 mm on one side and 1.8 mm on the other side. An inclined part was formed in the die hole, injection molded at 50 ° C, and the length of the surface line was cut to about 250 mm. The preform was preliminarily dried at a temperature of 70 ° C and a relative humidity of 20% for 3 to 5 minutes so that the molded surface was not clumped by controlling the air jet pressure so that the cut surfaces were dispersed evenly and the pores were maximized. In this drying, an injection surface was prepared by drying at a temperature of 53 ° C. and a relative humidity of 40% for 60 minutes and cooling to room temperature with cold air. The shape of the surface line formed through the second injector according to the present embodiment is shown in Fig. 6A, and the shape of the surface line after the drying process is completed is shown in Fig. 6B. 7 shows a part of the surface line on which the drying process is completed. As shown in the figure, it is confirmed that the thickness is different according to the die hole passing area on the same surface line (refer to FIG. 7), and the continuous wave in the longitudinal direction is formed in the surface line area passing through the relatively thick 1.8 mm die hole in the surface line (See Figs. 6A and 6B).
