Since the filtration resistance depends upon the porosity, the resistnace steadily increases as the liquid passes through the cake if the solids are compressible. In order to treat quantitatively the filtration problem in addition to the various parameters, it is necessary to know the relationships among the rate of flow, pressure on the liquid, and the porosity. Tiller calculated the P_x-distribution curve within filter-cakes in constant pressure filtration, ad determined the relationships between the solid pressure and porosity based upon the Kozeny's permeability law. So we made compression experiments, using the Shoyu and Sake mashes, and applied the experimental data to the plotting the P_x-distribution curve. After this we calculated the equiblium porosity and obtained the following experimental equations ;for Shoyu mash ; ε=0.81 P_s^-0.086 for Sake mash ; ε=0.74 P_s^0.011 The relationships between the porosity and x/L for fermentation mashes were in agreement with the results obtained by Tiller, using compressible slurries, e.g. kaoline.
