<P>PROBLEM TO BE SOLVED: To improve the efficiency of sterilization by low-energy electronic beam. <P>SOLUTION: This sterilizer is composed of a duct 2 passing a liquid current and an electronic beam generator 3 introducing the electronic beam stream in the liquid current in the duct 2 through an electronic beam transmission window 5. The electronic beam stream intersects substantially perpendicularly to the flow direction of the liquid current, and the orthogonal width intersecting perpendicularly to the flow direction of the liquid current is smaller than the double of the effective flight distance of the electronic beam stream. The sterilization efficiency can be improved by low energy electron beam. The width in the orthogonal direction is approximately equal to the effective flight distance of the electronic beam stream, and the utilization efficiency of the low energy electronic beam is higher. It is important that the width in the orthogonal direction is equal to or less than 0.5 mm. Thus, the width of the liquid current is set smaller and the low energy electronic beam is effectively used. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
