<p>PROBLEM TO BE SOLVED: To provide a material treatment device which can cope with a problem of closure of a through-hole in the material treatment device or a change of treatment conditions due to the closure.SOLUTION: A material treatment device 30 includes first and second channels 41, 42 through which fluid can flow and a boring member 50 which can rotate around a center shaft. The boring member 50 includes a lateral circumferential surface 52, a space 54 formed on an inner part of the boring member 50 and a plurality of through-holes 59 extended from the lateral circumferential surface 52 to the space 54. A part 55 of the lateral circumferential surface 52 is exposed to the first channel 41, the other part 56 of the lateral circumferential surface is exposed to the second channel, the boring member 50 is rotated and, thereby, positions of the part 55 and the other part 56 on the lateral circumferential surface 52 are changed.</p> |
