Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used for the initial drying of dried noodles, and specifically, the present invention is directed to dry noodles that can provide dried noodles with a delicious texture. This invention relates to an initial drying device.

[Conventional technology]

The more water added to noodles during manufacturing, the more delicious the texture will be; in general, hand-made noodles, which have a delicious texture, have a water content of 50-55%.
Manufactured with an added amount of water.

However, when making noodles using a machine, if the amount of water added is 50 to 55% as in hand-made noodles, in the drying process after cutting into M-line, there is a lot of elongation and sag, and it is difficult to make the product of the specified size. Therefore, the amount of water added in machine noodle making is 4
The limit was about 0%, and the texture was significantly inferior to hand-made noodles.

The problem is that the drying process after cutting into noodle strings takes a surprisingly long time. This is caused by the noodle strings becoming long and sagging.

Therefore, we dried the noodle strings using a drying heater.
By drying by irradiating far infrared rays as shown in Publications No. 0-172265 and No. 61-111662, the time required for the drying process is significantly shortened and the noodle strings are prevented from stretching and sagging. 5. Adjust the amount of water added to the noodles for the most delicious texture.
It was considered to set it to 0-55%.

[Problem that the invention seeks to solve]

However, the method of drying noodle strings in a short time using a drying heater has the problem that only the surface of the noodle strings is dried due to high heat, resulting in surface deterioration of the product and poor texture.

In addition, the method of drying by irradiating far-infrared rays can dry the noodle strings as desired in a short time, and because the far-infrared rays heat the noodles from the center, the inside and surface of the noodles do not change in quality. While this method has the advantage of being able to remove moisture from the noodles at the same time and producing noodles with a delicious texture, it is difficult to irradiate far-infrared rays evenly and evenly to all the noodle strands that are cut out from the noodle strip. There are problems such as uneven irradiation and uneven drying, resulting in the production of noodle strings with an uneven amount of water added, and uneven elongation rate, resulting in the production of noodle strings with different lengths. there were.

Therefore, the technical problem of the present invention is that when noodle strings cut out from a noodle making machine are irradiated with far infrared rays for initial drying,
To provide dried noodles that do not stretch and sag despite the amount of added water and have a delicious texture by uniformly irradiating all the noodle strings with far infrared rays.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) Noodle strings immediately after being made can be freely conveyed by hanging them on a noodle stick that is conveyed at a constant speed by a conveying device.

(2) On both sides of this conveyance path, the suspended noodle strings are irradiated with far infrared rays using gas as a heat source for 0.5 to 10 minutes to remove 5 to 20% of the water content of the noodle strings. An infrared generator shall be provided.

However, in this case, a far-infrared generator that uses gas as a heat source and emits far-infrared rays is a device that completely burns the fire injected from a gas burner in a combustion chamber, adjusts this combustion gas to a constant temperature, and sends it to a radiation tube. It means something that heats the radiation tube and emits far infrared rays.

[Effect]

The above means works as follows.

■The element of (1) above is that the #1 wire immediately after being made by the noodle making machine is lined up and hung on the 11 wire rod, and the conveying device transports it at a constant speed (for example, about 10 m/min) to the next drying device. Transport towards.

■The factor (2) above is that far infrared rays are irradiated from the far infrared generators installed on both sides of the conveyance path to the noodle strings hung on the rolling pin, so far infrared rays are applied to every single strand. can be irradiated uniformly, thus providing dried noodles with a constant degree of dryness and a delicious texture.

In addition, by irradiating the noodle strings with far infrared rays for 0.5 to 10 minutes, 5 to 20% of not only the surface moisture but also the internal moisture can be removed without deteriorating the JL.
The noodle strings become porous due to the movement path created when the moisture inside quickly escapes to the outside, so when boiling the noodle strings, the permeability of hot water is good and the boiling time is shortened, and the surface of the noodle does not melt when boiled, making it elastic. It is possible to provide noodles with a chewy texture and good taste after boiling.

Furthermore, drying using far infrared rays can remove water from the noodle strings in a short time, and the length of the highly hydrated noodles hanging on the noodle strings is shortened by drying, which has an extremely significant effect in preventing the noodles from stretching. do.

As described above, the above-mentioned technical problem aa can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
