PROBLEM TO BE SOLVED: To provide the subject sterilizing device increasing a pulse-electric field treatment in a state at a high temperature, improving the sterilization effect, suppressing the temperature after the treatment as low for preventing the quality reduction by making a distance between electrodes at a sterilization treatment part as gradually larger from the entrance part of a liquid state material over to its exist. SOLUTION: This sterilizing packaging device for a liquid state material is provided with a sterilization treatment part 4a having two electrodes 6, 8 arranged by taking a distance (d) with each other and flowing the liquid state material 2 such as a food, cosmetic material, etc. between both electrodes 6, 8, and a pulse electric source 14 for impressing a pulse voltage between the two electrodes 6, 8 of the sterilization treatment part 4a, and making the distance between the two electrodes 6, 8 of the sterilization treatment part 4a as gradually larger from the entrance part of the liquid state material over to its exit. Further, at the entrance part 10 where the electrode distance (d) is small, a relatively high pulse electric field is impressed on the liquid state material 2, and on the other hand, at the exit part 12, a relatively lower pulse electric field is impressed for capable of obtaining the liquid state material having a low temperature elevation to prevent the quality reduction. |
