Description

[Detailed Description of the Invention] The present invention relates to a filter cloth used in the process of pressing various soy sauce strains.

The method of pressing various soy sauce strains has been improved and automated in recent years, but the main process is the soybean process.

In this seeding process, conventionally, the various methods are injected into the filter cloth, the edges are folded up, the various methods are wrapped, a lid filter cloth is placed on top of the filter cloth, and the seeding process is repeated. After that, pressure was applied to squeeze out the liquid, that is, raw soy sauce.

The role of the lid filter cloth in this strain pressing process is to prevent the various seeds from leaking out, to prevent the filter cloth wrappers from adhering to each other after pressing, and to serve as a passage for the filtered sap. By increasing filtration and squeezing efficiency, and by using different materials for the filter cloth and lid filter cloth, the stacked filter cloth wrappers (filter cloth wrapped with various methods) can be prevented from bending during pressurization. An even more important role was to increase the recovery rate of raw soy sauce through uniform pressurization.

Figures 1 to 5 show such a conventional squeezing method. First, a filter cloth 1 is spread and various methods 2 are injected (Figure 1).
Fold the two opposite sides of the filter cloth (Figure 2), then fold the other two opposite sides (Figure 3), and cover it with the lid filter cloth (3 or 4) to cover the exposed areas. (Figures 4 and 5),
This was piled up, repeatedly pumped, and further pressurized by a water pressure machine using its own weight to collect the liquid (raw soy sauce).

In the filter cloth packets stacked in this way, the fourth
The number of filter cloths and lid filter cloths in each part of A, B, and C in the figure is 2. 4. In Figure 5, which uses a large lid filter cloth, there are 2 pieces each. 5. There will be 3 pieces.

Therefore, as the compression progresses and the whole becomes thinner, there is an imbalance in which the filter cloth remains thick in area A and is not squeezed to a certain extent, while in area B, the filter cloth is sufficiently compressed due to the thickness of the filter cloth. will occur.

In order to eliminate this imbalance, in the conventional manual method, when reloading filter cloth wrappers, the filter cloth wrappers are folded in two at appropriate intervals between the filter cloth wrappers 5, as shown in Figure 6. was placed so that the filter cloth had the same thickness as the whole in parts A and C in Figs. 4 and 5, and was pressurized uniformly.

Automatic seeding equipment does not allow filter cloth wrappers to be reloaded, so folding bags cannot be inserted, making uniform pressurization difficult.

For this reason, attempts have been made to insert spacers such as rubber plates or plywood plates during the raising of seeds, but they require time and effort to insert spacers every few pieces, have poor elasticity, and tend to damage the filter cloth that comes in contact with the plates. There are many disadvantages, such as the troublesome springing of the spacer when peeling the lees after finishing.

Another attempt has been made to use a thick lid filter cloth, but this has the disadvantage that it takes more time than conventional manual seeding because it increases the number of errors in removing the lid filter cloth.

In addition, in an automatic seed raising device, it takes about 30 seconds for one cycle of frying seeds, including placing on a filter cloth, injecting moromi, folding a lid, and placing on a filter cloth, of which approximately 5 seconds are required for placing the lid on the filter cloth.

If there is a mistake in removing the lid filter cloth, the proportion of the lid filter cloth placement process will increase as corrections are made.

Furthermore, mechanisms for detecting, holding, and transporting the lid filter cloth are required, resulting in a complex and expensive machine as a whole.

The present invention provides a filter cloth that eliminates the above-mentioned drawbacks, and streamlines the soy sauce pressing process and wraps the soy sauce in the filter cloth. This shortens the term.

Furthermore, in detail, by attaching the thickness-adjusting filter cloth integrally to the center of the filter cloth and raising the seed, the thickness of the filter cloth can be made uniform, and the work of placing the filter cloth on the lid can be omitted. It shortens the time required for raising seeds, and the effect is particularly great when raising seeds using an automatic seed raising device.

Embodiments of the present invention will be described below with reference to FIGS. 7 to 10.

In FIG. 7, a thickness-adjusting filter cloth 7 having the same shape as the exposed portion of FIG. 3 is attached to the center of the filter cloth 1.

In FIG. 8, a thickness-adjusting filter cloth 8 having the same shape as the lid filter cloth 4 shown in FIG. 5 is attached to the center of the filter cloth 1.

Note that the broken line in the figure indicates a fold line. The thickness-adjusting filter cloth can be attached to the filter cloth integrally by sewing, gluing, lining, or various other known methods.

The thickness-adjusting filter cloth may be made of the same material as the filter cloth, or may be made of a different material and weave.

Further, the number of thickness-adjusting filter cloths to be attached may be one or more.

The thickness-adjusting filter cloth may have any shape as long as it fulfills the role of the thickness-adjusting filter cloth.

Since the present invention has such a configuration, when the filter cloth is used, the thickness of the filter cloth becomes uniform, and the wrapped liquid juices can be passed through the filter cloth through the same route as in the conventional filter cloth, and the thickness can be adjusted. It completely flows out through the filter cloth, and the flow rate remains unchanged from that of the conventional filter.

Since the filter cloth to which this thickness-adjusted filter cloth is attached has the same function on both sides, the function and effect will not change even if it is used inside out.

As described above, when the filter cloth to which the thickness-adjusting filter cloth of the present invention is attached is used, the seeding operation becomes a cycle of placing the filter cloth, injecting moromi, and folding the cloth, and the operation of placing the filter cloth on the lid is omitted.

Therefore, mistakes in removing the lid filter cloth are eliminated, and the time required for the seeding cycle is reduced by more than 20% compared to the conventional method, so that a large amount of seeds can be seeded in the same amount of time.

Furthermore, since the automatic seed lifting device does not require a lid filter cloth mounting mechanism, the mechanism of the machine becomes simple, inexpensive, requires less installation space, and has the effect of reducing failures.

Furthermore, when cleaning the filter cloth, the thickness-adjusting filter cloth is also cleaned at the same time.
The cleaning efficiency is greatly improved, and there is no need to remove the lid filter cloth when removing the lees (separating the lees from the filter cloth wrapper that has been squeezed).

Further, the filter cloth to which the thickness-adjustable filter cloth of the present invention is attached can be used in the conventional seeding process as well as in the automatic seeding process.

Next, in the present invention, since the thickness-adjusting filter cloth is attached to the filter cloth in advance, it is possible to use a thickness-adjusting filter cloth of a complicated shape or a thickness-adjusting filter cloth of an appropriate thickness.

Figures 9 and 10 show another embodiment of the present invention, which includes a cross-shaped thickness-adjusting filter cloth 9 that is slightly thicker than the filter cloth as shown in Figure 9, or a rectangular filter cloth 9 as shown in Figure 10. When two filter cloths are combined to form a thickness-adjusted filter cloth 10,
By injecting the various methods into the filter cloth and folding it, the thickness of the filter cloth becomes more uniform over the entire surface, so even pressure is applied evenly without the need for spacers or folding bags, improving the recovery rate of raw soy sauce. .

This will be explained below by giving examples.

Example A filter cloth with a thickness-adjustable filter cloth sewn on, which is slightly thicker than the filter cloth shown in FIG. 10 (the present invention), a combination of filter cloth and lid filter cloth (conventional method 1) shown in FIG. Automatic seed raising is carried out using a combination of cloth and a thickness-adjusting filter cloth with the shape shown in Figure 10 and a lid filter cloth with the same shape (two pieces sewn together in a cross shape) (conventional method 2). went.

A 1m square filter cloth was injected with 121 Methods for Aging Soy Sauce, folded into a 70 cm square, and 200 filter cloths were made.

By the next morning, it was allowed to sag naturally due to its own weight, and then low pressure pressurization (equivalent to a 12-inch water pressure machine) was applied for one day, and high pressure pressurization (equivalent to a 16-inch water pressure machine) was applied for two days.

No reloading or folding was performed.

The results are shown in Table 1.

As is clear from this table, with the filter cloth according to the present invention, the seeding time was short, there were few mistakes in picking, and the moisture content of the lees was relatively uniform throughout, and the average moisture content was low.

In Conventional Method 1, the raising time was a little long, there were a few mistakes in picking, the moisture content of the lees was very uneven, and the moisture content of the lees was high.

In Conventional Method 2, the shape of the lid filter cloth was complicated and heavy, so there were many mistakes in picking and the time for raising the seeds was long, but the moisture content of the lees was relatively uniform throughout and the average moisture content was low.
