There are few studies on dehydration by compression. In our previous reports, we established the theory of compression dehydration by adding compressibility to Ruth's theory which was developed for the non-compressible cake layer.In this paper, we deduced the method of computation for dehydration mass during the compression process from this theory, i.e. we obtained an experimental equation (14) by plotting the specific flow rate (Δυ/Δθ)/(υ_T-υ)[1/(sec)]vs. time θ [sec] on logarithmic paper. In the case of this analysis simiilar to previous paper, the compression process was recognized to be divided into two step, the first characterized by transfer of the free liquid and the second characterized by transfer of the residual liquid. (Δυ/Δθ)/(υ_T-υ)z^2=β_2(θ/(z^2))^<-β1>…(14)where z is the initial mass of slurry. The experimental equation (eq. 15) of yield (υ/υ_T) was derived from eq. 14 and made it possible to analize the compression process during long periods. In this equation we learn that yield during the complete process is indicated as the function of (θ/z^2). υ/(υ_T)=1-exp{-(β_2)/(1-β_1)(θ/z^2)^<1-β_1>}…(15)The following slurries were used in this experiment : 1. Fermentaiton mashes prepared from soy-beans. 2. Broth of Endomyces. 3. Residue of raw sweet potato starch.
