PROBLEM TO BE SOLVED: To provide the subject sterilizer simple in structure and capable of conducting low-temperature sterilization in high energy efficiency even in the case of high-flow sterilization operation on an industrial production scale through clarifying the requirements for the dimension of a sterilization vessel section. SOLUTION: This sterilizer has such a design that the pulse width τof pulse voltage Vp to be applied from a pulse source 20 onto a sterilization vessel section 10 is set at <100 ns, and the space (d) [m] between two electrodes 12 and 14 in the sterilization vessel section 10 is set so as to satisfy the relationship, d>√(LGN)/(0.3τρf)} (wherein, L is the inductance [H] of the circuit connecting the pulse source 20 and the sterilization vessel section 10, G is the flow [m<3> /s] of a liquid material 2, N is the total pulse frequency [times] applied onto the sterilization vessel section 10, τ is a pulse width [s], (f) is the pulse repeating rate [Hz] of pulse voltage Vp, and ρ is the resistivity [νm] of a liquid material 2). |
