Description

  The present invention relates to a method for dyeing licorice used for tatami mats and cocoons, which are licorice products, and a method for producing the cinnamon products.

  Conventionally, the production of licorice products has been carried out by using a) a sorting process for sorting mud-dyed licorice, b) a humidifying process for humidifying the mulberry sorted by this sorting process, and c) a loom for the humidified licorice by this humidifying process. And a weaving process for weaving. Prior to the sorting step, usually, a step of immersing the cut grass into muddy water and mud-dying, and then a drying step of drying with thermal power are performed. By passing through such a process, the unique green color inherent in Reeds is maintained.

On the other hand, in response to demands from the market, in recent years, antibacterial treatments have been provided for cocoon products such as tatami mats. The present applicant has soaked and dyed coconut grass in tea juice and dyed it in a subdued color suitable for tatami mats and koji. (See Patent Document 1).
JP-A-11-303367

  However, although the licorice product described in Patent Document 1 certainly has an antibacterial effect and is finished in a calm color, it is inevitable that it is slightly different from the original color of licorice. In addition, the so-called “nejiro”, which was originally a problem with licorice products, could not be resolved.

  Here, “root white” means that the root portion is whiter than the center portion in the length direction of the weeds, and the root portion of the weeds growing in the field is in the field. Because it is covered with skin (the skin is peeled off to make it into a product), white skin is inevitably produced.

  If many of these roots appear on tatami mats and folds, it will appear to be inferior in quality, so the roots of the roots that are the roots may be cut and used. turn into. In the first place, it is extremely uneconomical to discard any functionally unaffected parts as a grass.

  The present invention has been made in order to solve such problems, and provides a method for dyeing licorice and a method for producing the licorice product, which can extremely easily reduce the occurrence of root whiteness from licorice products as much as possible. The purpose is to do.

  (1) In the environment where the tea extract was atomized, a method for dyeing camellia by exposing the camellia for a predetermined time to dye.

  (2) In the method for dyeing licorice of (1) above, an antioxidant is added to the tea extract.

  (3) It has a sorting process for sorting mud-dyed weeds, a humidifying process for humidifying the weeds sorted by this sorting process, and a weaving process for weaving the weeds humidified by this humidifying process with a loom. In the method for producing a licorice product, a humidifying solution used in the humidifying step was used as a tea extract, and the method for producing a licorice product for dyeing the licorice by the humidifying step was used.

  (4) In the method for producing a licorice product of (3) above, an antioxidant is added to the tea extract.

  According to the present invention, the original color of the licorice can be dyed firmly and extremely easily up to the root part of the licorice, and the whitening appearing in the licorice product can be prevented as much as possible. Moreover, the antibacterial effect is caused by the catechin contained in the tea component.

  The method for dyeing licorice according to the present embodiment is by exposing the licorice for a predetermined time in an environment in which the tea extract is atomized.

  That is, the grass is stored in a predetermined casing, and the tea extract is misted and drawn into the casing. The means for making mist is not limited, and the means for drawing mist into the housing is not limited. Preferably, the misted tea extract is circulated to fill the housing.

  Then, for example, if the licorice is exposed for about 4 to 6 hours, the licorice can be dyed in the original green color of the licorice, and even the fundamental part that is originally whitish can be dyed. Therefore, the so-called “nekaku” becomes inconspicuous and can contribute to quality improvement in the woven table products such as tatami mats and cocoons obtained after weaving. In addition, in this embodiment, the time which exposes a camellia grass in the environment which atomized the tea extract is 5 hours.

  It has been confirmed experimentally that even if the tea extract is simply sprayed on, for example, by spraying it, the dyeing result is not green but rather close to yellow. Although it is known that it does not stain green, it can be dyed to the original green color of licorice according to the dyeing method described above.

  In addition, the antibacterial effect of catechin contained in tea can be a hygienic licorice product with an antibacterial effect.

  In the above-described method for dyeing licorice, it is preferable to add an antioxidant to the tea extract in advance. By adding an antioxidant, it is possible to prevent the tea extract from being altered or discolored.

  By the way, as the tea extract, it is preferable to use an extract having a concentration of 4 to 5% from the viewpoint of the degree of dyeing. In order to produce an extract from tea, it is impossible to extract it as much as 5%, and if the concentration is less than 4%, the dyeing effect does not occur sufficiently and the original green This is because it becomes thinner. In addition, it was found from the experimental results that in the case of 4% extract, the staining effect is produced, but the degree of staining is slightly lower than in the case of staining with 5% extract. Yes.

  The method for dyeing licorice according to the present embodiment can be applied to a humidification step in the production process of licorice products such as tatami mats.

  That is, as a method for producing a licorice product, there are a sorting process for sorting dyed licorice, a humidifying process for humidifying the cocoon grass sorted by this sorting process, and a weaving machine for weaving the licorice humidified by this humidifying process. Forming process. In such a method for producing a licorice product, the humor is dyed by the humidification step using the above-described moisturizing solution as the tea extract.

  FIG. 1 is an explanatory diagram showing steps of a method for manufacturing a licorice product in the present embodiment.

  As shown in the drawing, first, in the harvesting process 1, the soy grass is cut, and then in the mud dyeing process 2, the cut grass is soaked in muddy water made by mixing dredged soil with water so-called mud dyeing. After muddy dyeing, the grass is dried by heating and stored.

  Next, in the sorting step 3, the licorice is sorted by a length suitable for the final product, and the head and the base are aligned.

  Then, in the humidifying step 4, the original suppleness is returned to the grass and the subsequent weaving step 5 is smoothly performed, and humidification is performed with an appropriate amount of water in order to improve the finish. In the present embodiment, in the humidifying step 4, the above-described tea extract is used as a humidifying liquid used for humidification, and the licorice is dyed while being humidified in the humidifying step 4. That is, the humidifying step 4 includes a dyeing step.

  Thereafter, in the weaving step 5, the humidified and dyed licorice is processed into, for example, a tatami mat using a loom.

  Then, in the finishing step 6, the woven product is finished and thermally dried. Soybean products are made and shipped in this way.

  FIG. 2 is a schematic explanatory view showing the humidification step 4 and the weaving step 5 described above. As shown in the drawing, the humidification device 10 described later is used in the humidification step 4 (see FIG. 3).

  In this embodiment, a tea extract is used as the humidifying liquid used in the humidifier 10, but the tea extract can be generated using, for example, autumn / winter bancha.

  For example, a case where 20 liters of tea extract having a tea concentration of 5% is prepared will be described.

  1.25 kg of bancha is placed in an exposed bag 20 made of cotton or the like, and 25 liters of water is put into a can 30 that has been boiled with a heating device such as a gas stove. During the course, the tea bag 20 is shaken so that the tea is uniformly extracted throughout the hot water, and is left for about 6 minutes after the fire is extinguished.

  And it cools, applying water to the outer side of the can body 30, and when it cools, the exposed bag 20 which accommodated the tea is taken out from the can body 30. FIG.

  Next, 48 g of ascorbic acid is added as an antioxidant 40. Then, for example, the tea extract is forcibly cooled using the refrigerator 50 or the like. This cooling is for suppressing the progress of oxidation of the extract.

  FIG. 3 is a schematic explanatory view of the humidifier. The tea extract obtained as described above is stored in the tank 11 of the humidifier 10 shown in FIG.

  The humidifying device 10 is sometimes called a “scraper” and has a well-known structure. As shown in the drawing, a humidifying space 12 that can accommodate a bundle of cigarettes is formed. The tank 11 provided, a water supply path 16 for pumping the tea extract in the tank 11 to a tray 15 formed on the ceiling of the housing 13 by a pump (not shown), and a plurality of channels formed on the bottom surface of the tray 15 A filter housing portion 17a that houses a multi-layered filter 17 made of a fine mesh wire net that receives tea extract dripping from the through-hole, and the filter housing portion 17a can be blown longitudinally, and the tip of the filter housing portion 17a can be blown. A circulation air passage 18 having a base end connected to the other end plate of the humidification space 12 and a blower fan 19 disposed on the base end side of the circulation air passage 18. And be prepared To have. Reference numeral 14 denotes a jacket portion formed so as to cover one end plate of the housing 13, and the upper end is connected to the filter housing portion 17 a and the lower end is connected to the tank 11 via the bottom of the housing 13. ing. That is, the jacket portion 14 forms a part of the circulation air passage 18.

  The humidifying process 4 using the humidifying device 10 will be described. A bundle of cigarettes is stored in the humidifying space 12, and the tea extract stored in the tank 11 is pumped up and sent to the tray 15; The blower fan 19 is driven.

  The tea extract is dripped from the through-hole of the tray 15 and cut like a fine particle by the wind sent by the blower fan 19 while passing through the fine filter 17 to be misted. It is sent into the humidification space 12. That is, moist air containing a mist of tea extract is sent into the humidification space 12. Since the moist air circulates in the circulation air passage 18 and the tea extract liquid is constantly dripping on the filter 17 from the tray 15, the humidified space 12 is always in an environment of high humidity.

  In this way, the bundle of licorice is exposed for about 5 hours in the humidified humid space 12 where the tea extract is present as a mist.

  As a result, moisture suitable for the weaving process 5 in the subsequent process is given to the cocoon grass, and the entire cocoon grass is dyed in a color as close as possible to the original green color of the cocoon grass. Although the tea extract is a color close to brown, the dyed camellia has a color that approximates the original green color of camellia. And since the root part is dyed firmly to such a root part, in the subsequent weaving process 5, the root white which appears in the camellia product obtained by weaving using a loom is reduced as much as possible. Can greatly contribute to quality improvement.

  In addition, the amount of catechin contained in the tea extract in the present embodiment is 0.4%, and the obtained licorice products such as tatami mats have antibacterial and deodorizing effects, and thus are highly hygienic consumers in recent years. It will be widely accepted.

  In the present embodiment, as specifically described in the humidification step 4 in the production process of the licorice product, the dyeing (humidification) time of the licorice is set to about 5 hours.

  Usually, when producing licorice products, the humidification time is about 6 hours. If the cutting time is greatly cut for 6 hours, it is not necessary for weaving, and there is a risk that the weeds will be cut during weaving. This is because the moisture content of the water becomes higher than necessary, and it may be difficult to weave. In addition, if the humidification time is long, the original color of the grass may drop and discolor.

  However, according to the present embodiment, even in 5 hours or 4 and a half hours, the same amount of moisture as that of 6 hours, which is a humidifying time in the normal step of manufacturing the grass, could be given to the grass. Therefore, in this embodiment, it can be shortened by 1 hour to 1 hour 30 minutes from the normal humidification time, so that the manufacturing efficiency can be improved and the cost can be reduced.

  As mentioned above, although this invention has been demonstrated through embodiment, this invention is not limited to the above-mentioned embodiment.

  The concentration of the tea extract can be appropriately changed. Also, tea is not limited to autumn / winter bancha. In addition, the humidifier 10 can be suitably used alone as a device for dyeing licorice.

It is explanatory drawing which shows the manufacturing process of a licorice product. It is not the typical description which shows a humidification process and a weaving process. It is a typical explanatory view of a humidifier.
