Abstract

PURPOSE:To make it possible to obtain continuously noodles having uniform qualities, by increasing the extrusion speed of a dough sheet through an extruder more than the cutting speed of the noodle strips by a cutter for the noodle strips, sensing the sags of the noodle strips between the cutter and the extruder, and adjusting the extrusion of the dough sheet. CONSTITUTION:A dough sheet 1 is extruded through an extrusion die 3 of a screw extruder 2 and subsequently cut into noodle strips 5 by a cutter 4 for the noodle strips 5. In the process, the extrusion speed of the dough sheet through the extruder 2 is increased more than the cutting speed of the noodle strips 5 by the cutter 4 to cause sags of the dough sheet 1 between the cutter 4 and the extruder 2. The sags are then sensed by a sensor 7 to adjust the dough extrusion according to the sags. As a result, the aimed noodles having uniform qualities can be prepared rapidly and continuously by the method.

Description

[Detailed Description of the Invention] Noodles whose main ingredient is wheat flour are produced by mixing a certain amount of salt water with wheat flour and mixing for 10 to 20 minutes to produce noodle dough, which is then rolled. Rolls are used to roll the noodles thickly at first and then thinly in order to determine the final thickness of the noodle strips according to the size of the lines on the cutting blades, after which noodle strips of various sizes are made using the cutting blades. For example, the number 12 is divided into 12 axes between about 3Q mm, and is referred to as 8-12 for ``udon'', 15-18 for ``chilled wheat'', 20-28 for ``somen'', and so on. This roll-rolled noodle is made by adding flour to cold water (usually salted).
A common manufacturing method is to add water, knead the mixture at room temperature, roll it at room temperature, and cut it into linear shapes with a cutting blade. With this method, it is easy to manufacture a series of noodle strips, and all you have to do is cut them out in a line with a cutting blade. Since the flow line of the noodle strings is cut out at a constant speed, a fixed amount of noodle strings can be easily manufactured using a cutting cutter with a constant rotation speed.

On the other hand, when producing noodle strings by extruding a set of screws, a head is attached to the tip of the screw, and a die is attached to the tip of the screw.
The starch of the wheat flour is gelatinized by the heat generated by the strong pressing force of about 100 kids by the screw, and the axis is extruded through the many small holes of the die, thereby making it possible to produce various pasta foods such as spaghetti and macaroons.

Currently in use: Special public service (1973-5019), public public service (45)
In the case of 5-24558%, kneading for producing noodles is only carried out by screw extrusion, and then rolling is performed sequentially using several stages of rolls, so roll rolling cannot be omitted. However, the above pasta food manufacturing machine (Pasta!!A
), all the processes are completed by the pressure of the screw, and the noodle strips are finished to the point where they just need to be made into a linear shape.

However, in this pasta machine, the pressing force from the screw is applied to the die through the head, so even if a large number of small holes are evenly placed in the round die, the noodle strings that are extruded from the small holes will not be able to fit into the die. The center part becomes longer and the outer part becomes longer, so it does not always come out uniformly (Figure 3,
(See Figure 4).

In order to make this kind of thing as accurate as possible, elongated harmonica-shaped dies are also used instead of round dies, and these can also be made long or short, as shown in Figures 3 and 4. Currently, when producing dried spaghetti, mackerel, etc., the extruded axis is placed on a hanging rod and the lower end is immediately trimmed to make the length even.

The present invention extrudes a noodle strip from an extrusion die of a screw extruder, and then cuts the noodle strip into noodle strings using an axial cutter,
The noodle strip extrusion speed by the extruder is made faster than the noodle strip cutting speed by the cutting machine, and the slackness of the noodle strip between the cutting machine and the extruder is detected, and the The present invention relates to an extruded noodle manufacturing method and an apparatus thereof characterized in that the extrusion of the noodle strips is adjusted to maintain the above-mentioned noodle string cutting speed. A water/flour mixer 9 is installed in the mixer 9, and the mixer 9 is sealed with an opening/closing lid 10, internal air is sucked to the outside and maintained in a vacuum state, and a stirring rotary blade 11 is pivotally supported inside. The bottom of one end of the mixer 9 communicates 13 with the starting end of a screw extrusion cylinder 12 disposed at the bottom of the mixer 9, and an extrusion screw 14 is pivotally supported within the extrusion cylinder 12. Further, the tip head 15 of the cylinder 12 is provided with a circular noodle strip extrusion die 3 shown in FIG. 2, and a notch is formed in the circular extruded noodle strip 1.

The extrusion screw 140 rotation shaft 16 is a reduction gear 171.1

is formed. A noodle string cutting machine 4 is arranged on the floor surface 26 at a position close to the manufacturing machine 6. A noodle strip vinci roll 27, 27 is provided on the upper part of this cutting machine 4, and the roll 2
7. A constant speed rotating noodle string cutting blade roll 28.28 is provided below 27, and a noodle Is size cutter 29 is provided below it,
Further below, there is a noodle string constant speed conveyor 30 or a boiling tank (
(not shown) Intermittent constant speed moving boiling soil bucket) 3
1 is provided. , a noodle band 1 slackness sensing device 7 is provided between the noodle string cutting machine 4 and the extrusion noodle manufacturing machine 6,
The device 7 may be a phototube, an IJ switch, or the like. The extrusion screw 14 is rotated at a reduced speed by the electric motor 25, and the speed at which the noodle strip is extruded from the die 3 due to the rotation is variable and set to be faster or slower than the constant circumferential speed of the cutter roll 28, 28. A variable speed motor is used for the electric motor 25, or a switch or a resistor is used, which is set slightly faster than the constant circumferential speed of the cutting blade roll 28, and changes the speed of the electric motor 25 or turns it on or off according to the sensing operation of the slack sensing device 7. A rotation control device for the screw extruder 2 is formed.

In the present invention, the noodle strips 1 are extruded from the extrusion die 3 of the screw extruder 2, and then the noodle strips 1 are passed through the noodle strip cutting rolls 27 and 27 of the noodle strip cutting machine 4 to the noodle strip cutting rolls 2B.
, 28 to cut out the noodle strips 5 at a constant speed. Extruded noodle band 1 located between 4 and extruded joint 2 marked -
causes downward slack. This slack can be sensed by the sensing device 7 described above. For example, the light weight below,
Shut off the pipe to the loose noodle strip 1 or open the limit switch 7 on the F side of the loosened noodle strip 1, and the electric motor 25 is activated by the signal.
The noodle strip extrusion speed is reduced or stopped by slowing down or stopping. In this way, the extruded noodle strip 1 rises due to the traction force of the cutting blade rollers 28, 28 having a constant circumferential speed, and the upper phototube or limit switch 7'' is cut off or closed, and the speed of the electric motor 25 is increased or started. The extrusion speed is increased, the extruded noodle strip 1 is loosened downward, and the same operation as described above is repeated.

Conventionally, it has been difficult to match the extrusion speed and cutting speed, and the flow of the extruded noodle strip 1 between the screw extruder 2 and the cutter 4 is not always uniform, so the flow from the extruded noodle strip 1 to It was extremely difficult to continuously cut out the noodle strings 5 using the constant speed cutting rolls 28, 28. In addition, a method can be considered in which the extrusion speed r9 of the screw extruder 2 is adapted to the noodle string cutting by the cutting machine 4, but in this method, the noodle string cutting speed fluctuates I- or the cutting stops. When producing boiled spaghetti at a constant speed of t[1], the movement of the boiling packet must be varied or stopped depending on the cutting of the noodle strings. When boiling, the speed at which the same packet is boiled in water is not constant, and as a result, the resulting spaghetti takes different amounts of time, making it difficult to obtain one of constant quality.

Since the present invention is based on the above-mentioned method and N, the noodle strip 1 can be produced very quickly using a pasta machine, and the same noodle strip 1 can be produced very quickly.
Not only can the noodle strings 5 be continuously cut out, but the cut noodle strings 5 can also be cut out at a constant speed and connected to subsequent processing steps such as a boiling machine or a frying machine, resulting in uniform quality. There is an effect that noodles can be obtained.
