Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a filter cloth used in a tank for mashing miso such as soy sauce and sake. Although soy sauce moromi is mainly described here, the present invention can be widely applied to brewing moromi.

(Prior Art) Conventionally, soy sauce moromi is filtered and squeezed by laying a filter cloth of about 1 m square on a lifting frame of about 70 cm square, placing the inside and outside of moromi 10 and folding the filter cloth in the shape of a cross. Place a 40 cm square lid filter cloth. (Refer to Fig. 9 to Fig. 12) This is called a lifting tank, which is repeated, stacked, and first filtered by its own weight, that is, naturally dripping, and then low pressure pressurization and high pressure pressurization are performed by a hydraulic machine to finish the compression. To do.

In the conventional lifting tank, the folding of the filter cloth 1 is shown in Figs.
11 is in the shape of a cross, and the lid filter cloth 4 is placed as shown in the explanatory view of FIG. 12, so the meal after pressing is shown in FIG.
There are two pieces of filter cloth 1 in the portions a and c, and four pieces in the portion b.
Immediately after the frying tank is formed, the thickness of the moromi 2 layer is much larger than the thickness of the filter cloth 1, so there is almost no partial bias in pressurization. Since the ratio of the thickness of the cloth 1 becomes large, as shown in FIG. 14 which is a sectional view of the folded portion, the portion b has a large proportion of the filter cloth 1 and is sufficiently pressed to reduce the cake residue. In the portion (including the portion c), the proportion of the filter cloth 1 is small and the cake 5 becomes thick, so that it is not sufficiently pressed. Therefore, the dregs in the b portion have a small amount of water, and the dregs in the a (c) portion have a large amount of water, which results in an increase in the moisture content as a whole. In order to prevent uneven pressure from being applied to the parts in this way, conventionally, re-loading is performed in the middle of the pressurizing process, the filter cloth wrapping is folded in half, and the a (c) part is covered about 10 times. The number of sheets was about%. This was called a folded bag, but the pressure was not completely uniform even if the folded bag was put in, the water content of the whole meal was still high, and the recovery rate of soy sauce was low. For this reason, a large amount of drying energy is required when the lees 5 are dried and used as feed or the like.

Further, if the frying frame is enlarged and a large amount of moromi 2 is fried at one time, re-loading becomes substantially impossible, folding bags cannot be put, and the lees moisture increases.

Further, since the automatic lifting tank that does not use humans does not reload the sheets, folding bags cannot be put into the bag, so that the water content of the lees is uneven and the water content of lees as a whole is increased.

Therefore, in order to reduce as much as possible the water content of the lees as described above, the applicant of the present invention proposed "Japanese Patent Publication No. 55-46146" to put a taste on a square or rectangular filter cloth, and to put the filter cloth against each other. By the first step of folding so that both ends of one of the two sides of the two pairs contact each other, and by the second step of folding so that the other two sides do not touch each other. , The lid filter cloth having the same shape and twice the thickness of the filter cloth is placed in the concave portion caused by the difference in the number of stacked filter cloths by folding the filter cloth folded in a square or rectangular shape by enclosing Moromi as a whole. We proposed a moromi fried tank method consisting of the third step, and made it possible to reduce the water content of the lees by making the pressing uniform.

The figure showing this method is an explanatory view of the folding of the filter cloth of FIGS. 15 to 17, an explanatory view of the lid filter cloth placement of FIG. 18, a sectional view of the lees of FIG. 19, and FIG. It is sectional drawing of a folding part. A lifting frame is placed on the filter cloth 1 shown in the fifteenth section, and the placing range 3 of the moromi 2 is restricted. Next, as shown in FIG. 16, two opposite sides of the filter cloth 1 are bent to bring the ends into contact with each other. Next, the other two opposite sides are bent so that their ends do not come into contact with each other to form a shape as shown in FIG. As shown in FIG. 18, a lid filter cloth 8 having the same shape as the filter cloth portion bent the first time but having a thickness twice that of the filter cloth 1 except the second bent portion of the filter cloth 1 in such a state is shown in FIG. Avoid the bent part of the second time and place it. In the lees classification diagram of FIG. 19, the filter cloth 1 has two pieces in the d portion and four pieces in the e portion. Therefore, as shown in FIG. 20, which is a cross-sectional view of the folded portion, the upper surface side shows a state in which the filter cloth 1 is three times as thick as the filter cloth 1. When this is squeezed as described above, every portion of the lees 5 has the same thickness and sufficient squeezing is possible, so that the moisture content of the lees 5 is the same in each portion, the recovery rate of soy sauce increases, and the lees 5 It requires less drying energy.

(Problems to be solved by the invention) As described above, it is possible to reduce the water content of the lees 5, but since the filter cloth on the upper surface of the frying tank has three layers, the thickness of the lid filter cloth 8 Requires a thickness twice that of the filter cloth, and the soy sauce content impregnated in the filter cloth 1 and the lid filter cloth 8 cannot be recovered, and there is still a problem for improving the recovery rate.

Further, there is a problem that it is difficult to wash the thick lid filter cloth in the step of washing the filter cloth and the lid filter cloth after the pressing.

(Means for Solving the Problem) A moromi 2 is placed on a square or rectangular filter cloth 1, and this filter cloth 1
The first step of folding so that both ends of one of the two sides of the two opposite sides of the pair overlap each other, and the second step of folding so that the other two sides of the pair do not contact each other In the filter cloth 1 used in the mashing tank comprising the step of, the thickness of the filter cloth 1 in the folding portion in the second step is set to 1/2 of the thickness of the filter cloth 1 in the other portion, and Of the overlapped portion in the first step, the thickness of the portion which is not folded in the second step is set to 1/2 of the other portion, and the thickness of the portion which is folded is 1/4, or One side is 1/2 and the other side is notched.

(Operation) According to the present invention, the total number of the filter cloths 1 in the upper and lower tanks is two, so two filter cloths, that is, the total number of filter cloths is twice as many as the number of tanks in the tank. The soy sauce recovery rate can be improved accordingly.

(Embodiment) The present invention is a method of folding the filter cloth 1 of the lifting tank, which is almost the same as the improved conventional method, but the filter cloth itself is improved.

In the first embodiment, as shown in the development view of the filter cloth 1 in FIG. 1, a portion where the moromi 2 is not placed, a portion where this portion is folded and overlapped, and another portion where two sides are opposite are overlapped. The thickness of the portion is set to 1/2 of the other portion d (the portion indicated by e), and among the portions that overlap when folded on the opposite two sides, the portion on which the moromi 2 is not placed and this portion are folded. The thickness of the portion that folds and overlaps is 1/4 of the other portion (the portion indicated by f). FIG. 2 is a state diagram in which the filter cloth 1 is folded (the left side of the figure shows a state in the middle of folding), and the portions where the thickness of the two opposite sides is halved are overlapped. The folded part is 1 / thick in thickness
The filter cloth part e of 2 overlaps. 3 is a sectional view taken along line AA in FIG. 2, FIG. 4 is a sectional view taken along BB, and FIG. 5 is a sectional view taken along CC. As is clear from these figures, the overlapping parts of the filter cloth 1 are all 1/2 or 1/4 in thickness,
The total thickness of the upper and lower surfaces of the filter cloth 1 is two.

In the second embodiment, as shown in the development view of FIG. 6, in the development view (FIG. 1) of the first embodiment, the 1/4 thickness portion of one end of the overlapping portion is 1 / thickness. The thickness is 2 and the 1/4 thickness of the other end is a notch. FIG. 7 is a folded state diagram (the left side is a state in the middle of folding), and FIG. 8 is a DD sectional view of FIG. 7. In this case, there is no 1/4 thick portion on the upper surface, but since the number of layers in the 1/2 thick portion is 3, the total number of filter cloths 1 is two.

(Effects of the Invention) Since the total thickness of the double thickness is smaller than the total thickness of the double thickness of the conventional example improved as described above, the following effects are obtained.

1) It is possible to increase the number of tanks for one cage.

2) The number of devices may be small in relation to the above item.

3) The recovery efficiency of soy sauce is improved.

4) Since the lid filter cloth is omitted, the burden of wastewater treatment after washing the filter cloth and the lid filter cloth is reduced.

5) Since the filter cloth and the lid filter cloth are expensive, the cost can be reduced.
