Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for raising brewing strains such as soy sauce strains, and particularly relates to a method for raising seeds of brewing strains such as soy sauce strains. The surface is evenly wrapped in a filter cloth with the thickness of 5 sheets, and the filter cloth is evenly wrapped even during low-pressure and high-pressure squeezing processes.
The present invention also relates to a molding and packaging method for brewing strains that can be pressurized and squeezed well.

Hereinafter, details of the method of the present invention as well as the conventional method will be shown using various soy sauce strains as examples.

For various soy sauce strains, which are known to be liquids that are difficult to separate from solid and liquid, it has long been considered best to wrap them in a filter cloth, undergo a long period of natural drip filtration, and then gradually increase the external pressure to squeeze them.

The operation of wrapping soy sauce in a filter cloth and stacking it one after another in a frying frame is called "agetane," but the traditional method of operating the hot water tank is as shown in Figures 1 to 3. Using a rectangular cylindrical lift frame 1 of about 70 cm, a filter cloth 2 with a side length of approximately 100 cm + n is spread on the top surface of the frame 1, and various plants 3 are placed on the top surface of the filter cloth 2 located inside the lift frame 1. Usually 10 to 13jl! Fill it evenly, fold the edges of the filter cloth 2 outside the lifting frame 1 inward, and place a 45 to 50 square filter cloth lid 4 on the top surface.
Cover it with ~ to finish working on one piece.

Next, the bottom plate (not shown) associated with the lifting frame is lowered by one layer of the filter cloth wrapped plants, and the same operation as described above is repeated in sequence, until the lifting frame 1 reaches full capacity and the bath operation is completed. After passing through the natural sag of gravity filtration, the squeezing process is completed by performing low-pressure and high-pressure squeezing using a hydraulic press.

In this way, since the conventional method of packaging soy sauce products using filter cloth is a parallel type, each corner of the soy sauce is wrapped with four pieces of filter cloth, while most of the other parts are wrapped with four pieces of filter cloth. will be wrapped in two filter cloths.

These parts with different numbers of filter cloths still contain a large amount of soy sauce and are fluid during the process of bath operation and natural dripping, so no local moisture deviation due to self-weight pressure is observed. However, as the process moves to low-pressure and high-pressure squeezing, the strain layer becomes hard, and the thickness of the lees and moisture content become uneven due to local differences in the thickness of the filter cloth. In other words, despite strong pressure, the moisture content of the lees is the lowest at each corner where the four filter cloths are wrapped and molded, and the other two filter cloths are wrapped and molded to be the lowest. It is relatively expensive. In order to eliminate such unevenness in the moisture content of the lees, a so-called folding bag has traditionally been inserted when reloading during the pressing process, but this method requires a lot of effort and expense. The effect of reducing lees moisture did not increase.

The purpose of the present invention is to eliminate the disadvantages of the conventional method described above, and to cover the surface of the strain layer filled in the rectangular filter cloth spread over the top surface of the filter cloth with a thickness of five filter cloths. It is an object of the present invention to provide a molding and packaging method for various brewing methods, which can be wrapped uniformly and pressed evenly and well even during low-pressure and high-pressure crushing processes.

For this purpose, the method of the present invention is configured as follows.

In other words, the method for molding and packaging brewing strains of the present invention involves stacking the filter cloth wrapped around the brewing strains one after another in a rectangular cylindrical lifting frame. Spread the filter cloth on the upper surface of the lifting frame, fill the upper surface of the filter cloth located inside the lifting frame with various strains, and make sure that two corresponding sides of the four sides of the filter cloth outside the lifting frame are opposite sides of each of the lifting frames. The first operation is to wrap the surface of the plants with two layers of filter cloth by folding them alternately so that they reach the inside of the filter cloth, and the remaining two corresponding sides are moved toward the opposite sides of the lifting frame so that they do not touch each other. A second operation of folding the filter cloth as shown in FIG. Moreover, it consists of a third operation of covering the filter cloth lid with a thickness equivalent to three times the thickness of the filter cloth, among which,
The filter cloth and the filter cloth lid are used repeatedly to provide a small gap between the end of the folded margin folded in the second operation and the end of the filter cloth lid covered in the third operation. It is characterized in that the elongation that occurs is pre-shrinked.

In the first operation, the filter cloth 1o used in the method of the present invention is
Out of the four sides of the filter cloth outside the lifting frame, two corresponding sides are folded alternately so that they reach the inside of each opposite side of the lifting frame, and the surface of each strain is wrapped in two layers of □filter cloth. Therefore, its length in the vertical direction needs to be approximately three times the vertical length of the lifting frame used, and in the second operation, the remaining two corresponding sides are moved in the direction of each opposite side of the lifting frame. Since it is folded so that it does not touch, it is necessary to have a horizontal length that is larger than the horizontal length of the lifting frame, and a width that is smaller than twice the horizontal length of the lifting frame. Figure 4).

The filter cloth lid 11 is formed when the entire filter cloth lid 11 is packaged and formed into a square or rectangular shape by the first operation and the second operation.
It has almost the same shape as the recessed part 13 created by the thickness difference between the overlapping folding allowances 12 of 0, and has a thickness equivalent to three times the thickness of the filter cloth 10. That is,
As shown in FIGS. 4 to 9, the filter cloth 10 is spread on the upper surface of the lifting frame, and the upper surface of the filter cloth 10 located in the lifting frame is filled with a predetermined amount of seeds 14 and evenly leveled. Filter cloth 1 outside the lifting frame
By folding alternately so that two corresponding sides of the four sides of 0 reach the inside of each opposite side of the lifting frame, the surface of the stocks 14 is wrapped in two layers of filter cloth. Then, when the remaining left and right corresponding sides are folded so that they do not touch each other in the direction of the opposite sides of the lifting frame, both the left and right ends of the stocks 14 are covered with a total of five filter cloths, and the ends of the stocks 14 are A recessed portion 13 with a height equivalent to three filter cloths is formed in the center, and by covering this recessed portion 13 with a filter cloth lid 11 having a thickness equivalent to three times the thickness of the filter cloth 1o. The entire surface of the plants 14 is uniformly wrapped with a filter cloth having a thickness of five sheets.

The filter cloth lid 11 may be a single piece with a thickness three times that of the filter cloth 1o, or it may be formed by stacking three filter cloths 1o.
It may be made to have a thickness three times that of the one shown in FIG.

In addition, in order to prevent the filter cloth and filter cloth lid from overlapping each other due to the elongation of the fibers during squeezing, the folding margin 12 is
It is necessary to create a slight gap between the end of the filter cloth lid 11 and the end of the filter cloth lid 11.

In other words, to ensure that the vertical and horizontal lengths of the filter cloth and filter cloth lid remain constant even after repeated use, it is necessary to shrink the filter cloth and filter cloth lid in advance by the amount of elongation. is important. Therefore, under various conditions such as the pressure method (70 kg/crl), the size of the filter cloth and filter cloth lid, the filling amount by various methods, the fiber material (nylon), and the count, the shrinkage factor is set to 1 to 4. I lost it in an experiment.

This is shown in Table 1.

Table 1 Also, the horizontal folding allowance of the filter cloth was determined as shown in Table 2.

Table 2 Therefore, if the horizontal length of the lifting frame is a, the vertical length is b, the thickness of the packed layer of stocks is t, and the horizontal folding allowance is C, the dimensions of the filter cloth and filter cloth lid are The results are as follows.

The vertical dimension L1 of the filter cloth: (3b+2t) Kl ≦Ll <3b+2 is the horizontal dimension L2 of the filter cloth: (a +2t+2c) K2 ≦L2 <a +2t+
2c Vertical dimension L3 of the filter cloth lid: b-3≦L3<b 8 dimension L4 of the filter cloth lid (a-2c) K4≦L4kua-2c According to the method of the present invention, the top surface of the plants is 5 It will be wrapped evenly with layers of filter cloth, and the thickness of the filter cloth will be uniform throughout, so
Even in the case of high-pressure squeezing, all of the plants wrapped in filter cloth are pressed with uniform pressure, and the moisture content of the lees is almost evened out over the entire surface of the lees. In addition, since the soy sauce is squeezed using five layers of filter cloth, the recovery rate of soy sauce is higher than before. Furthermore, the S-bending phenomenon of the filter cloth-wrapped stocks, which conventionally occurred during the squeezing process, has been extremely reduced, making it possible to continue operation smoothly, and the curved deformation of the filter cloth-wrapped stocks has been reduced compared to the conventional method. The amount has been reduced significantly and uniform compression has become possible.

In addition, the gap d between the edge of the horizontal folding allowance of the filter cloth and the edge of the filter cloth lid.
was found to be within a small range of 1 to 1.5% per meter of length of the filter cloth bag.

Example (method of the present invention) A filter cloth with a vertical length of 3.03 m and a horizontal length of 1.22 m and a filter cloth lid with a vertical length of 0.97 m and a horizontal length of 0.75 m were used for frying. Seed manipulation was performed.

The packaging process involves spreading the filter cloth over the top of a 1m square lifting frame so that the center lines of the lifting frame and the filter cloth are aligned, and placing the seeds on the top of the filter cloth located inside the lifting frame. Fill the filter cloth uniformly with 30Il, and perform the first and second operations of folding the four sides of the filter cloth outside the lifting frame, and make sure that the recess formed by the overlapping thickness of the folding allowance is the same shape as the filter cloth, and A third operation was performed manually to cover the recess with a thicker filter cloth lid three times as thick as the filter cloth lid.

The subsequent operations were carried out in the same manner as before, with 350 sheets per tank, and after completing the processes of 24 hours of natural dripping, 24 hours of low pressure pressing, and 24 hours of high pressure pressing, the moisture content of the lees was measured.

(Conventional method) Using a 1.35m square filter cloth in a 1m square lifting frame, 307 plants were collected. The filter cloth was filled evenly, the four sides of the filter cloth were folded in a grid pattern, and a 0.93 m square filter cloth lid was placed on the top surface, and this operation was repeated to process 350 filter cloths.

Then, the pressing steps of 24 hours of natural dripping, 24 hours of low pressure pressing, and 24 hours of high pressure pressing were completed, and the moisture content of the lees was measured.

The moisture content of both lees was measured by heating in a dryer at 105°C for 6 hours. The results are shown in Table 3.

Table 3 As is clear from this table, the average lees moisture content of the lees processed according to the method of the present invention is much lower than that of the conventional method (indicating that good squeezing was performed).
