Description

DETAILED DESCRIPTION OF THE INVENTION The present invention removes stains such as soy sauce oil, lacquer, and squeezed lees that adhere to soy sauce moromi press cloth and cause clogging.
The present invention relates to a method and apparatus for reproducing.

The conventional method for recycling the ash cloth used for pressing soy sauce moromi is to put the dirty ash cloth into a rotating drum, refrain from using detergents such as soap for food hygiene reasons, and recycle it with water or water. Using only warm water, the cloth is brought into intense frictional contact with each other,
This is then carried out by rinsing with a large amount of water or warm water and dehydrating.

However, if the sarufu obtained in this way is stacked thickly and left for a long time, the sarufu will generate heat and emit a bad odor, so when it is used to press moromi, the bad odor will be mixed into the moromi liquid (raw soy sauce). There is a risk that the moromi liquid will migrate and deteriorate the flavor of the moromi soup.

In addition, since the regeneration method uses only water or hot water,
Among the dirt that adheres to the sarufu, that is, soy sauce oil, lacquer, squeezed lees, etc., the soy sauce oil is not separated and removed sufficiently, and the soy sauce that remains without being removed makes the sarufu easy to slide, causing the hazakufu to become slippery. It has the disadvantage of being prone to clogging. Therefore, if moromi is filled and packaged in such monkey cloth and stacked one after another in multiple tiers, it will not be possible to meet the demand for shortening the natural pressing time, which is the biggest problem during the moromi pressing process, and the planned time will not be met. The squeeze operation cannot be completed within the scheduled time. Furthermore, if you attempt to press moromi-filled sarufu stacked in multiple tiers from the top and bottom or from the left and right, the sakufu will tend to slide against each other and collapse during the compression process, and the zasuku will also tend to burst. This method requires a high level of skill to operate, and also requires a great deal of effort to interrupt the pressurizing operation midway through and reload the sape cloth that has slipped back to its original position. An object of the present invention is to provide a method and apparatus for regenerating soy sauce moromi pressing cloth, which eliminates the above-mentioned drawbacks and problems in the regenerating method for soy sauce moromi pressing cloth. Hereinafter, the method and apparatus of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic vertical cross-sectional view showing a specific example of an apparatus for carrying out the method of the present invention. 1 is introduced into a brushing chamber 2, through a guide loaf 3 provided in the chamber, and introduced into the contact portion of a pair of brush rollers 4 and 5 that rotate in contact with each other, where the monkey cloth The coarse lees adhering to the surface is brushed off.

In addition, 7 is a squeezed lees storage box. Next, the paper cloth is introduced into a rough washing liquid chamber 8 via a guide roller 6, and two sets of spray nozzles 12, 13 that project water toward each other via guide loaves 9, 10, and 11 provided in the chamber. and 14
, 15, to easily remove dirt adhering to both the left and right sides of the monkey cloth.

Reference numeral 16 is a drain pipe for vertical washing and drainage. Next, the cloth is passed through the guide rollers 7, 18 and 19 to the cloth feeding device A.
will be introduced in

This device may have any configuration as long as it is a device that can feed the alkaline solution storage tank 23 of caustic soda, potassium carbonate, soda carbonate, etc., which will be described later.
For example, as shown in FIG. 1, there are drive rollers 20 and 21 that rotate in contact with each other. The cloth is introduced into the contact area of the drive rollers 20 and 21, and is thrown into the alkaline solution storage tank 23 containing the alkaline solution 22 by these dry rolls. The condensing device 24, which has a stick for cleaning, allows the cloth to come into sufficient contact with the alkaline solution 22.The cloth is made to have enough contact with the alkaline solution 22 in the alkaline solution for a predetermined period of time. It is preferable to use it loosely.

In addition, the most preferable method for contacting the sarufu with the alkaline solution is to immerse the sarufu in the alkaline solution as described above, but it may also be a method of spraying or coating.

The concentration of the alkaline solution varies depending on the material of the monkey cloth, the degree of dirt attached to the cloth, etc., but it is preferable to set the concentration to be enough to thoroughly wash the dirty cloth. The pH of the alkaline solution when in contact is 7.
．． It is preferably 0 or more, particularly 7.5 to 11.0. That is, the stains on the cloth are mainly caused by soy sauce, lacquer, and squeezed lees, all of which are substances that exhibit acidity when dissolved in water. Therefore, as the amount of contact between the alkaline solution and the dirty monkey cloth increases, the alkali in the solution disappears and shifts to the acidic side, so the alkali equivalent to the amount lost is replenished into the solution. Then, the pH of the solution is adjusted to 7.0 or more, particularly 7.5 to 11.0. In addition, the contact time between the sand cloth and the alkaline solution should be such that the dirty sand cloth is brought into contact with the alkaline solution of the above concentration, and the stain on the sand cloth is almost completely eluted and separated into the alkaline solution. is preferred, and usually 1 minute or more, particularly 5 to 30 minutes.

In addition, the temperature of the alkaline solution is preferably higher as long as it does not damage the material of the monkey cloth, but for example, when using ordinary nylon monkey cloth, it is more than 4000, especially 60 to 65
o○ is preferable.

Particularly when processing the 桨 cloth within the preferred temperature of the latter,
Harmful bacteria adhering to the cloth can be killed.
Next, the washed bell cloth is passed through the guide rollers 25 and 26 provided near the bottom of the alkaline solution storage tank 23 to the cloth placed near the storage tank 23. It is introduced into take-out device B. This take-out device B may have any configuration as long as it is a device that can take out the alkaline solution storage tank 23, for example, the first
As shown in the figure, there are drive rollers 27 and 28 that rotate in contact with each other. The paper cloth is introduced into the contact portion of the drive rollers 27 and 28, and is taken out from the alkaline solution storage tank 23 by these drive rollers. Next, the taken out hakufu is introduced into the dewatering and washing room 29,
It is introduced into the washing machine C for rinsing the paper cloth provided in the vertical dehydration washing chamber, and by this machine, the alkaline solution adhering to the paper cloth and the remaining dirt that was not washed in the alkaline solution storage chamber 23 are rinsed away. Wash.

This device includes a decompression pipe 31 having many water absorption holes 30 on the surface that comes into contact with the cloth, and six water absorption holes 30' facing each other.
The spray nozzle 32 is configured to spray hot water of 0 to 6,500°C, and the pressure reduction pipe is constantly maintained in a reduced pressure state by a vacuum pump (not shown). When the cloth passes through the water absorption hole 30 in a manner that closes it, the water projected from the spray nozzle 32 passes through the eyes of the monkey cloth and closes the water absorption hole 30.
The alkaline solution and dirt adhering to the cloth at that time are absorbed into the vacuum pipe 31 through the projection. In this way,
The cloth is washed and washed. Next, the rinsed moat cloth passes through guide loaves 33, 34 and 35,
Two sets of opposing spray nozzles 36, 37 and 38
, 39, where again between 60 and 6
It is thoroughly contacted with 5q○ of hot water to be rinsed, and then introduced again through guide rollers 40 and 41 between two sets of opposing spray nozzles 42, 43 and 44, 45, where it is further brought into sufficient contact with water. After being washed with water, it is introduced to the outside of the dehydration and washing liquid chamber 29 via the guide roller 46. In addition, 47 is a drainage pipe for washing and vertical drainage. In this way, the completely washed hakufu is introduced into a dewatering device D, where most of the water contained in the sarufu is removed by dehydration.

This dewatering device is composed of a decompression pipe 49 having many water suction holes 48 on the surface in contact with the paper cloth, and the decompression pipe is constantly maintained in a depressurized state by being conveyed to a vacuum pump (not shown) or the like. When the cotton cloth passes through the water absorption hole of the dewatering device so as to close it, the water adhering to the water absorption hole is absorbed into the depressurizing pipe 49. In this way, a monkey cloth whose function as a monkey cloth has been restored to the same extent as the new cloth can be obtained. Note that the recycled sarufu may have a slight alkaline odor, but in such cases, an acid solution* solution may be applied to the sarufu before or after the dehydration operation. preferable.

Examples of the acid solution include organic and inorganic acid solutions such as lactic acid, succinic acid, citric acid, fumaric acid, hydrochloric acid, and sulfuric acid, but lactic acid is preferred because it causes the least deterioration of the flavor of soy sauce. Next, the monkey cloth obtained in this manner is folded using a thin cloth folding machine (not shown) or the like, and is stored in a monkey cloth storage tank (not shown) in preparation for reuse.

Hereinafter, the effects of the present invention will be explained in detail by showing experimental examples. Example 1 Prepare 7 buckets containing 5 sheets of soy sauce moromi press cloth with a large amount of soy sauce oil, lacquer, lees, etc. and 20 pieces of water overflowing with 4,000 ml of water. Wash for 10 minutes while adding additives like the one listed above, and then wash the final product.
Adjust H as in the first notation, visually inspect the color of the cloth after washing, and collect 100 pieces of the 9E solution in the bucket into a graduated cylinder with a capacity of 2.
As a result of a 4-hour clarification test, the results shown in Table 1 were obtained.

Table 1 From the results, it is found that when the soy sauce moromi pressing cloth is brought into contact with an alkaline solution, the dirt adhering to the cloth can be eluted and separated into the solution, and the pH of the alkaline solution is adjusted to 7.0.
From the above, it can be seen that by keeping the value of 7.5 or higher, a sarufu with very good gloss can be obtained.

Example 2 Prepare four sections of soy sauce moromi pressing cloth with a large amount of soy sauce oil, coating, squeezed lees, etc. The first section was rinsed thoroughly with 4,000 ml of warm water as usual, and then washed with a large amount of water. After rinsing and dehydrating, the second section was made by spraying lactic acid solution (pH 3.2) uniformly on the fins of the dehydrated cloth obtained in the first section. W/V)% sodium carbonate solution for 15 minutes, washed by hand, rinsed with a large amount of water, and dehydrated. In the fourth section, the dehydrated monkey cloth obtained in the third section was soaked in a lactic acid solution ( pH 3.2) was evenly sprayed onto the cloth to obtain four types of recycled monkey cloth.

Next, the thus obtained hazafu was stacked to a thickness of 30 mm and left in a constant temperature room at 20 mm, and as a result of observing changes in texture, temperature, and odor over time, it was found that The results shown in the table were obtained. Table 2 (Note) The cloth temperature in Table 2 above is the average temperature at two points near the center of the cloth.

(Note 2) Each symbol in the "Change in odor" column in Table 2 above means the following. ×: Very poor (has a strong odor) ○: Poor (has a strong odor).

)○: Good (There is no bad odor, but there is a slight alkaline odor.)

) ◎: Very good (no bad odor or alkaline odor can be sensed at all.) From this result, we can see that after fully contacting the hazaku cloth with an alkaline solution, rinsing it and dehydrating it, the hazaku cloth obtained can be stacked thickly. It can be seen that even when left alone, it does not generate heat or become sticky to the touch, nor does its odor change. It has also been found that when an acid solution is added to the monkey cloth obtained in this manner, a sarufu that has no bad odor or alkaline odor can be obtained. Example 3 Recycled oak cloth of Category 1 obtained in Experimental Example 2 above (hot water treatment)
Using ``Category 3'' recycled ``Azaburi'' (treated with soda soda solution) and ``new ``Azaburi'' cloth, we separately filled and packaged ordinary soy sauce brewing moromi, and stacked each layer in 100 layers.Filling and packaging work at the 100th layer was completed. The height of the moromi was investigated, and the height of the recycled sarufu and Nitofu of category 3 was 94 and 92, respectively, with the case of recycled zarufu of category 1 being 100.

These results show that the recycled moat cloth treated with an alkaline solution according to the present invention has extremely good natural sagging compared to the recycled moat cloth treated with warm water according to the conventional method, and is almost the same as the new cloth.

As is clear from the above description, the present invention makes it possible to very easily remove and regenerate the soy sauce oil, lacquer, and lees adhering to the soy sauce moromi press cloth, which has been extremely difficult to remove in the past.

In addition, it retains almost the same functionality as Nitofu, which does not generate heat, emit a bad odor, or become sticky to the touch even if it is stacked thickly and left for a long time. Therefore, it is possible to obtain recycled cloth that is extremely easy to store and manage. In addition, since the recycled Azafu fabric obtained by the method of the present invention does not contain any soy sauce oil, the recycled Azafu fabric that contains soy sauce oil in the conventional method has a thin fabric that is piled up in many tiers during pressure pressing. The danger of the middle part protruding from the row and bending or the monkey cloth bursting is eliminated, so the level of skill required in the pressing operation is reduced.

In addition, one of the biggest problems in the soy sauce moromi pressing process, the natural pressing time due to stacking moromi-filled kakucloth, has been shortened, allowing the specified amount of moromi to be efficiently produced within the specified time. It can be filled and packaged in a predetermined amount of paper cloth.

In addition, since recycled sarufu is free of clogging to the same extent as new zarufu, it does not place any extra burden on the pressurizing machine. This can reduce the risk of bending or bursting the monkey cloth.

In addition, since Hazafu does not have any bad odor and is sterilized, unlike the recycled sarufu in the conventional method, the bad odor and bacteria that adhere to the sarufu are transferred to the moromi liquid when the moromi is pressed, resulting in flavor and flavor. , quality deterioration is almost completely eliminated. In addition, the alkalis used for preparing the alkaline solution of the present invention include caustic soda, potassium carbonate, and soda carbonate.
All of these are permitted as food additives.
Further, since the alkaline solution adhering to the monkey cloth can be completely removed by the washing liquid in the rinsing process of the present invention, no problem arises in terms of food hygiene.

Further, according to the apparatus of the present invention, even extremely large long monkey cloths can be regenerated extremely easily and continuously.

Hereinafter, the present invention will be explained in further detail by showing examples.

The apparatus of the present invention is set as shown in Fig. 1, and the largest size monkey cloth 1 of 2.0 cm and 100 mm length is passed through the contact surfaces of the brush rollers 4 and 5 and attached to the surface of the cloth. After separating and removing the coarse lees adhering to the surface of the saru cloth, the saru cloth was then passed between two sets of spray nozzles 12, 13 and 14, 15 for rough polishing.

Then, 4000
It is poured into the alkaline solution storage tank 23 containing the sodium carbonate solution (PHIO. After washing, the monkey cloth is taken out from the storage tank 23 by drive rollers 27 and 28, and then the soda cloth attached to the surface of the cloth is removed by a rinsing device C and the alkaline solution storage tank 23.
Spray nozzle 3 to remove the remaining dirt that could not be completely washed away.
2, the water is sucked and removed from the water absorption hole 30 into the vacuum pipe 31 for rinsing, and then passed between the two sets of spray nozzles 36, 37 and 38, 39 to spray 6,000 ml of warm water onto the cloth. Then, the cold water is passed between the two sets of spray nozzles 42, 43 and 44, 45 again and is sprayed onto the sand cloth to completely wash off the soda carbonate solution and dirt adhering to the sand cloth, and then the dewatering device In step D, moisture adhering to the surface of the monkey cloth was removed by dehydration through the water absorption holes 48, and a recycled long cloth was obtained. Example 2 A rectangular cloth with one side lw was immersed in 40q0 of 1% soda carbonate solution and washed with a sanding rod. , the state of colorless and transparent water suddenly changed to a dark brown emulsion.

After soaking in the trench, after 1 minute had elapsed with occasional bowing, the cloth was taken out, rinsed with a large amount of 4,000 ml of warm water, and then placed in a centrifugal dehydrator to obtain recycled monkey cloth.
Example 3 A 1 (W no V) % lactic acid solution was uniformly sprayed on the recycled paper cloth obtained in Example 2 above to obtain a recycled paper cloth from which the slight alkaline odor had been completely removed. Ta.
