Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for peeling off sake lees adhering to the surfaces of a filter plate and a press plate in a sake brewing press.

Conventionally, in a sake brewing press, filter plates and press plates, each with the same type of filter cloth wrapped around both sides, are alternately stacked and pressed together in a row in the left and right direction, and air pressure is injected into the press plates. The moromi was squeezed between the filter cloths.

However, as for the lees peeling work after the completion of pressing,
This is done by separating the filter plate and press plate one by one, but since the same type of filter cloth is used, lees mainly adhere to the filter plate side due to the structure, but this is not definitive. Sometimes, due to slight changes in conditions, it would stick to the pressing plate side, or it would break off and stick to both sides.

Therefore, if you want to efficiently peel off the lees using an automatic machine or the like, it is recommended to use a peeling machine equipped with two rows of scrapers that can simultaneously remove the lees from both facing sides of the opened pressing plate and the remaining filter plate. It shall be a device. Furthermore, it was necessary to position and fix each filter plate or pressing plate at a constant distance from the remaining plate after separation.

In view of the above-mentioned circumstances, the present invention aims to provide a method that can perform peeling using a peeling device with a simpler configuration and further reducing time.
In other words, filter plates and pressing plates, each having a filter cloth pasted on both sides, are alternately stacked and pressed together in a row in the left and right direction, and after pressing, the filter plates and pressing plates are separated one by one. In the machine, the filter cloth is made of a material that allows the lees to be easily peeled off from one of the left and right sides of each filter plate and the pressing plate, so that the lees adhere to only one side when the filter cloth is opened. This invention relates to a lees peeling method in a sake brewing mortar press, which is characterized in that the lees are peeled off only on one side.

To explain in detail based on the example shown in the figure, 1 is a mortar press;
A fixed pressure plate 1a is provided at the left end in a frame formed in a frame shape, and a movable pressure plate 1 is provided at the inner end on the right side.
b constitutes a pressurizing device including a hydraulic cylinder 1c which can move toward the left, and both pressure plates 1
A large number of filter plates 4 and compression plates 5 with filter cloths 2 and 3 pasted between them a and 1b are held in parallel in a stacked manner alternately, so that they can be brought into pressure contact by the operation of the cylinder 1c, and the return of the cylinder 1c The filter plate 4 and the pressing plate 5 can be separated by operation.

Reference numeral 6 denotes a traveling frame that can be run by straddling the guide rails 1d provided in parallel at the front and rear of the upper part of the mortar 1, and filters the water by means of holding members suspended from the front and rear, respectively. A separating device (not shown) for separating the plate 4 or pressing plate 5 and a peeling device (not shown) equipped with a scraper for peeling off the adhering lees are provided.

The filter cloths 2 and 3 are made to have different weaving methods, coarseness of weave, fiber thickness, etc. so that the filter cloth 2 side is easier to remove dregs than the filter cloth 3 side. A filter cloth 2 is placed on the left side of the plate 5, and a filter cloth 3 is placed on the right side of the plate 5.
are arranged so that the lees always adhere to the right side when opening.

The pressing plate 5 has rubber diaphragms 5b superimposed on both sides of the core plate 5a and sandwiched between the frame plates 5c, and when the filter plate 4 and the pressing plate 5 are mounted on the mortar press 1 and in a pressed state, there is no internal space. is maintained in a liquid-tight manner.

Therefore, each filter cloth 2, 3 is
In the meantime, moromi is injected, the liquid inlet is closed, and compressed air is injected from the air inlet (not shown) of the pressing plate 5 to expand the diaphragm 5b and press the moromi (the state shown in Fig. 2). After the pressure is released, the movable pressure plate 1b is moved backward, and when the first filter plate 4 is opened to the right by a separating device, the lees P will not adhere to the left side of the filter plate because the filter cloth 2 is attached thereto. , the lees P is attached to the right side of the first pressing plate 5 on the residual side.

Therefore, as shown in FIG. 3, the dregs P are peeled off using only one row of scrapers S provided in the peeling device. When the peeling is completed, the peeling device is again used to open the peeled pressing plate 5. In this case as well, since the easily peelable filter cloth 2 is attached to the left side, the lees P is removed.
is attached to the right side of the next leading filter plate 4 on the residual side. The lees P may be peeled off using the scraper S as before (FIG. 4).

In this way, due to separation, the lees P adheres only to the right side of the filter plate 4 or pressing plate 5 on the residual side.
Peeling work only needs to be performed on the first one on the remaining side.

Assuming that the filter cloth is a single piece made by connecting 2 and 3,
Similarly to the conventional method, it can be similarly implemented by winding it around a filter plate or a pressing plate.

As detailed above, when using the method of the present invention, two types of filter cloths are used so that the lees adhere only to specific surfaces of the filter plate and pressing plate, so only one row of scrapers is provided as a peeling device. In addition, since there is no need to position and fix the separated filter plate and pressing plate to predetermined positions one by one during peeling, the device as a whole can have a simple configuration.

Therefore, not only can the equipment cost be drastically reduced, but also the working time can be shortened, which brings about great effects.

In the figure, 1 is a mortar press, 2 and 3 are filter cloths, 4 is a filter plate, 5 is a pressing plate, P is a lees, and S is a scraper.

Claims (1)

[Scope of Claims] 1. Filter plates and compression plates, each having a filter cloth pasted on both sides, are alternately superimposed and pressed together in many columns in the left and right direction, and after compression, the filter plates and compression plates are separated one by one.
