2 The filtering device according to claim 1, is characterized in that the plurality of porous ceramic plates each comprise a filtering distribution defined between the first side and the second side of the porous ceramic filters, wherein at least two of the plurality of porous ceramic plates have significantly different filtration distribution.

3 The filtering device according to claim 1, is characterized in that at least one of the plurality of ceramic foundry filter comprises a first layer defining the first side of the porous ceramic filters and a second layer defining the second side of the porous ceramic plate, wherein the first layer and the second layer have a significantly different filtration distribution defined between the first side and the second side of the porous ceramic filters.

4 The filtering device according to claim 1, is characterized in that at least one of the plurality of porous ceramic filters has a filtering distribution limited between the first side and the second side of the porous ceramic plate, and the filtering distribution changes significantly in the radial direction of the porous ceramic filter.

5 The filtering device according to claim 1, is characterized in that each of the plurality of porous ceramic plates comprises an inner periphery defining the corresponding central hole, and the plurality of radial grooves have a first number of openings at the outer periphery. The first number of openings is more than the number of openings at the inner periphery of at least one of the plurality of porous ceramic filters.
