Conventionally, as shown in FIG. 9, a mash inlet of a filter structure of this kind is an inlet 2 of a pressing plate 1 and an inlet of a filter plate 3 corresponding to the inlet 2 as shown in FIG. 4 were opened to the same size. In this case, the mash to be injected is injected from the injection ports 2 and 4 to the entire area of the mash room 5 formed between the plates 1 and 3 through a slight gap between the pressing plate 1 and the filter plate 3. In this case, the width of the moromi injection could be as small as half or less the thickness of a filter frame (not shown) attached to the periphery of the pressing plate 1.

For this reason, in the case of fine sake such as ginjo sake,
In the case of squeezing the mash with a large amount of lees, it was not always possible to secure a sufficient opening width. For this reason, when the moromi lump enters the morm chamber 5 between the pressing plate and the filter plate, the narrow space is closed, and as a result, the morm chamber 5 into which the morm is not injected at all may be formed. Therefore, the mash room 5 into which the moromi was injected,
Since there is a moromi chamber 5 in which no moromi is injected, a pressure difference between the two moromi chambers 5 of, for example, 2 kg / cm ² is generated. This means that the pressing plate 1 or the filtering plate 3
There is a problem that it leads to the destruction and suffers a great loss.

It is an object of the present invention to make the size of the moromi inlet of the squeezing plate and the filter plate constituting the filter structure different from each other in size, and to set the inlet orifice on the side close to the upper or lower peripheral edge of each plate. The same volume on the same horizontal plane, increase the actual volume at the entrance of the mash room due to the difference in the size of the injection port, and perform filtration with low residual mash and good yield, and smooth mash injection without clogging. It is in.

Means for Solving the Problems The filtration structure in the mash press and squeezing device of the present invention which solves the problems of the prior art is as follows:
The following measures are adopted.

[0007] The above object is achieved by alternately laterally providing a large number of squeezed plates provided with a moromi inlet near the periphery and a filter plate provided with a moromi inlet corresponding to the above inlet. The moromi formed in the squeezed plate is squeezed in the squeezed mash formed by pressing the moromi filled in between the two plates with a pressurizing means and extracting and collecting the liquid. When,
The inlet of the size of the filtration plate corresponding to the infusion inlet causes each Ira, under side of both inlet side close to the lower peripheral edge of the pressing plate and the filter plate, is positioned on the same plane, both Injection
A large portion that communicates with the mash room by the amount corresponding to the difference in mouth size
This is achieved by forming the interval .

[0008] The above object is achieved by making the two inlets circular in diameter in the filtering structure of the mash press and squeezing device according to claim 1.

[0009] The above object is achieved by forming one of the inlets in the filter structure of the mash press and squeezing device according to the first aspect of the present invention to be longer in the vertical direction.
