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. 10-Fig. 13) This is called a lifting tank, and this is repeated, and stacking is carried out. First, filtration by self-weight, that is, natural dripping, is carried out, and then low-pressure pressurization and high-pressure pressurization are carried out by a hydraulic machine and the compression is completed To do.

In the conventional frying tank, the folding of the filter cloth 1 is shown in Figs.
12 is in the shape of a cross, and the lid filter cloth 4 is placed as shown in the explanatory view of FIG. 13, 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 thickness ratio of the cloth 1 becomes large, the ratio of the filter cloth 1 is large in the portion b as shown in FIG. 15 which is a cross-sectional view of the folded portion, and it 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.

Figures showing this method are explanatory views of folding of the filter cloth in FIGS. 16 to 18, explanatory views of lid filter cloth placement in FIG. 19, sectional view of lees in FIG. 20, and FIG. 21. It is sectional drawing of a folding part. A lifting frame is placed on the filter cloth 1 shown in FIG. 16 to restrict the mounting range 3 of the moromi 2. Next, as shown in FIG. 17, two opposite sides of the filter cloth 1 are bent to bring the ends into contact with each other. Next, the other two sides facing each other are bent so that their ends do not come into contact with each other to form a shape shown in FIG. As shown in FIG. 19, a lid filter cloth 8 having the same shape as that of the filter cloth portion bent for the first time and having a thickness twice that of the filter cloth 1 for 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. 20, the filter cloth 1 has two pieces in the d portion and four pieces in the e portion. Therefore, as shown in FIG. 21, which is a cross-sectional view of the folded portion, the upper surface side shows a state in which the filter cloth 1 has a thickness three times that of the filter cloth 1. If this is squeezed as described above, the lees 5 will have the same thickness in any part and sufficient squeezing will be possible, so that the water content of the lees 5 will be the same in each part, the recovery rate of soy sauce will increase, 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 contact or overlap each other, and the other step of folding so that the other two sides of the pair do not contact each other. Used in a mash flavor tank comprising a third step of wrapping the moromi flavor 2 as a whole by the step 2 and placing a lid filter cloth 6 or 7 on the upper surface of the filter fabric 1 folded as a square or a rectangle if necessary. In the filter cloth 1, 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 portions.

In addition, of the filter cloth 1 of the portion that is folded in the second step, the thickness of only the filter cloth portion of the outer portion on which the moromi 2 is not placed is set to 1/2 of the thickness of the other portion, and the moromi 2 There is a case where the thickness of the outer portion which is not placed and the portion where the outer portion is overlapped among the portions where the moromi 2 is placed is made 1/2 of the thickness of other portions.

(Operation) According to the present invention, since the filter cloth on the upper side of the tank is double,
Since one filter cloth, that is, the total number of filter cloths in the lifting tank can be saved, 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 in the developed view of the filter cloth shown in the first embodiment, the thickness of the outer portion to be bent, that is, the portion e on which the moromi 2 is not placed is half the thickness of the other portion d. The state in which the filter cloth 1 is folded is as shown in FIG. 2, and the filter cloth 1 is bent so that two facing sides of the non-thinned portion are butted against each other. (The left half of the figure shows the state in the middle of folding.) FIG. 3 is a sectional view of the folded portion, where d is the original thickness of the filter cloth 1 and e is the thickness. The part that was halved,
6 is a lid filter cloth having the same thickness as the filter cloth 1 (d).

In such a filter cloth, the total thickness of the filter cloth 1 and the lid filter cloth 6 on the upper surface of the frying tank is twice that of the filter cloth 1 and may be smaller than the conventional three times by one filter cloth.

In the second embodiment, as shown in the developed view of the filter cloth 1 in FIG. 4, the thickness of the portion e on which the moromi 2 is not placed and the overlapping portion f when the portion e is folded are set to 1 / th of the other portion d. It is supposed to be 2. FIG. 5 is a diagram showing a state in which the filter cloth 1 is folded (the left side of the diagram shows a state in the middle of folding). As in the case of FIG. The two folded sides are folded so that they are butted against each other, and the folded portion is such that filter cloth portions e and f having a thickness of 1/2 overlap.
FIG. 6 is a cross-sectional view of the folded portion, where the thickness of the filter cloth 1 other than the folded portion is 1 and the lower surface portion f is the folded portion.
Is 1/2, the f portion is 1/2 on the upper surface portion, and the e portion is 1/2 on the upper surface portion, which is twice the thickness of the filter cloth 1 as a whole. Since the thickness of the filter cloth 1 in the d portion other than the overlapping portion is doubled in total in the upper and lower portions, it becomes the same as the folded portion. A lid filter cloth 7 having the same thickness as the filter cloth 1 is placed on the entire surface of the frying tank to prevent the moromi 2 from protruding. In such a state, the thickness of the lees 5 is the same in each part as in the first embodiment, and the total thickness of the filter cloth 1 and the lid filter cloth 7 is also three times as thick as in the first embodiment. Same as the example.

The third embodiment is the same as the second embodiment except that the filter cloth portion having a thickness of 1/2 is the same as that of the second embodiment, as shown in the developed view of the filter cloth 1 shown in FIG. The cloth 1 is folded in a different manner, and the filter cloth 1 in the folded portion is folded so as to completely overlap as shown in FIG.

(The left side of the figure shows the state in the middle of folding.) In this way, the lid filter cloth can be omitted, and it becomes like the sectional view of the folded part in FIG. In the folded portion in the figure, the filter cloth portions e and f each having a thickness of 1/2 are tripled, and the total thickness is three times the thickness of the filter cloth 1, which is the same as the total thickness of the other portion (d portion). Therefore, it is the same as in each of the above embodiments.

(Effect of the Invention) Since the total thickness of 3 times is required as compared with the total thickness of 4 times as in 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 has a half thickness or 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.
