[Industrial applications]

 The present invention relates to an improvement of a filtration structure in a squeezing press of a mash.

[0002]

[Prior Art]

 A large number of squeezing plates and filter plates are hung vertically side by side on the machine body, and the mash filled between the plates is squeezed by a pressurizing means to extract and collect the liquid. Filtration structures in the field are generally known. (For example, see Japanese Utility Model Publication No. 50-23398, Japanese Utility Model Publication No. 52-54851, and Japanese Utility Model Publication No. 54-1626).

[Problems to be solved by the device]

 Conventionally, as shown in FIG. 9, the mash inlet of this type of filtration structure is such that the inlet 2 of the squeeze plate 1 and the inlet 4 of the filter plate 3 corresponding to the inlet 2 are opened to the same size. It was In this case, the injected mash is injected from the injection ports 2 and 4 through the small gap between the compression plate 1 and the filter plate 3 into the entire mash chamber 5 formed between the plates 1 and 3. In this case, the interval between the mash injections could only be less than half the thickness of the filter frame (not shown) attached to the peripheral edge of the pressing plate 1.

Therefore, in the case of high-grade sake such as Ginjo sake, or when squeezing mash with a large proportion of lees, it is not always possible to ensure a sufficient opening width. For this reason, when a lump of mash enters the mash chamber 5 between the pressing plate and the filter plate, this narrow space portion is blocked, and as a result, the mash chamber 5 into which no mash is poured may be formed. .. Therefore, since a mash chamber 5 into which mash is injected and a mash chamber 5 in which no mash is injected are formed, a pressure difference of, for example, 2 kg / cm ² , which is the mash injection pressure, is generated between the two mash chambers 5. This causes the squeeze plate 1 or the filter plate 3 to be broken, resulting in a large loss.

An object of the present invention is to make the size of the squeeze plate and the sill inlet of the filter plate constituting the filtration structure different from each other, and to increase the actual volume of the sill chamber inlet due to the difference in size. The purpose is to allow smooth injection of mash without clogging.

A filtration structure in a squeezing squeezing and squeezing device for extracting and recovering mash, in which the size of the smelt injection port formed in the compression plate and the size of the injection port of the filtration plate corresponding to the injection port are different from each other. Is.

【Example】

 Next, details of the embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a pressing plate, FIG. 2 is a front view of a filtration plate, FIG. 3 is a vertical end view of a filtration structure, FIG. 4 is a vertical end view of the same injection port, and FIG. 5 is an injection port of another embodiment. FIG. 6 is an explanatory view showing the positional relationship between the inlets of the compression plate and the filter plate in FIG. 4, FIG. 7 is an explanatory view showing the positional relationship of both inlets in FIG. 5, and FIG. It is explanatory drawing which shows the arrangement | positioning relationship of both injection ports of an Example.

FIG. 1 shows a squeezing plate 11 constituting the filtering structure of the present invention. As is clear from FIG. 3, the squeezing plate 11 is provided with a diaphragm membrane 12 made of an elastic material on both sides. Further, a filter cloth 13 made of a stretchable material is attached to the surface of the diaphragm membrane 12 so as to wrap the pressing plate 11. A syrup injection port 14 is formed in the lower center of the compression plate 11, the diaphragm film 12, and the filter cloth 13, and the diaphragm film 12 facing the injection port 14 is formed by the diaphragm film pressing ring 15. The filter cloth 13 is fixed on the diaphragm pressing ring 15 by the filter cloth pressing ring 15a. In the figure, 16 is a hanger, 17 is a residual air vent hole, 18 is a filter frame for fixing the diaphragm membrane 12 to the peripheral edges of both sides of the pressing plate 11, 19 is an air injection port, and 20 is a guide for a filter cloth mounting bar. , 21 are filtrate collection ports.

FIG. 2 shows a filter plate 22 that constitutes a filter structure, and as is apparent from FIG. 3, the filter plate 22 is covered with filter cloths 23 on both entire surfaces. At the center of the lower part of the filter plate 22 and the filter cloth 23, there is provided an inlet 24 of a mash that corresponds to the inlet 14 of the pressing plate 11, and the filter cloth 23 facing the inlet 24 part. The peripheral portion is fixed to the filter plate 22 by a filter cloth pressing ring 25. Then, as shown in FIGS. 3 to 8, the inlet 24 of the filter plate 22 is formed larger than the inlet 14 of the compression plate 11. In the figure, 26 is a hanger, 27 is a residual air vent hole, 28 is a filtrate recovery port, 29 is a bias pressure prevention pillow, 30 is a filtrate guide recovery groove, and 31 is a filter cloth mounting pin.

The pressing plates 11 and the filtering plates 22 are alternately arranged as shown in FIG. Further, between the compression plate 11 and the filtration plate 22, a mortar chamber 32 corresponding to the thickness of the filter frame 18 is formed, and at the lower portion of the mortar chamber 32, the size of the injection ports 14 and 24 is set. A large interval 33 corresponding to the difference of (3) is formed, and the lump of mash can be freely supplied from this interval 33 into the mash chamber 32.

As shown in FIGS. 3 and 4, the central axes of the inlets 14 and 24 of the squeeze plate 11 and the filter plate 22 coincide with each other. As is clear from the relationship diagram of FIG. 6, the lower part of the injection port 24 having a large diameter is located below the lower side of the injection port 14. Therefore, the moromi that has intervened in this lower step remains as it is until the end and is washed out without being filtered, and the residual amount is proportional to the number of filter plates 22 and cannot be ignored.

As a means for solving this, as shown in FIGS. 5 and 7, the lower sides of both the injection ports 14 and 24 are located on the same plane, so that the mash remaining at the injection port 24 of the filter plate 22 remains. The amount of water is greatly reduced to improve the filtration yield of mash. Further, in FIG. 8, the inlet 24 of the filter plate 22 is formed to be long in the vertical direction for the same purpose.

Further, in the above embodiment, the injection port 14 of the compression plate 11 is made small and the injection port 24 of the filter plate 22 is made large, but conversely, even if the injection port 14 is made large and the injection port 24 is made small, it is the same. Therefore, it is not limited to the illustrated embodiment that the sizes of the injection ports 14 and 24 are different from each other.

Further, in the above embodiment, the injection ports 14 and 24 of the mash are formed in the lower center of the pressing plate 11 and the filtering plate 22, but these injection ports 14 and 24 are respectively formed in the pressing plate 11 and the filtering plate 22. Since the same effect can be obtained even if it is provided at an appropriate place on the upper part, it is not specified in particular in the illustrated embodiment.

[Effect of the device]

 As described above, according to the configuration of the present invention, the following effects can be obtained. (a) By making the size of the inlet of the press plate different from that of the filter plate, it is possible to reasonably increase the interval for communicating with the mash chamber by an amount corresponding to the difference in size. When injecting high-quality sake such as liquor or mash with a high percentage of lees, even if there is a lump of mash, it can be easily injected into the mash. Therefore, unlike the prior art, it is possible to rationally prevent the squeeze plate and the filter plate from being broken due to the pressure difference of the mash injection pressure without the mash being injected and supplied into the mash chamber. (b) According to the experiment, when injecting Daiginjo mash with a 50% rice cake ratio, it took 5 hours to inject it into a conventional press-pressing machine, whereas in the case of the present invention, it took 3 hours. As is clear from the completion of the mashing in time, we were able to improve operating efficiency by drastically shortening the time.
