This paper deals with the design of a practical continuous heat sterilizer without perfect piston flow profile.If the turbulent diffusion model is applied to the holding tube of a sterilizer and the rat eequation of the first order reaction is assumed on the thermal death process of bacteria, bacterial concentration at the outlet of the sterilizer can be stated as follows, as a function of P_eB and N_r.C=N/(No)=4β exp((P_eB)/2)/((1+β)^2 exp(β(P_eB)/2)-(1-β)^2 exp(-β(P_eB)/2))β=√<1+(4N_r)/(P_eB)>This equation has a great number of combinations of P_eB and N_r, in other words.L/D and θ, and does not have any definite solution. But this can be solved by stating the minimum cost of the apparatus, which turns out to be the optimal design.
