PROBLEM TO BE SOLVED: To suppress a temperature rise in the inside of a centrifugal filter during continuous running.SOLUTION: A centrifugal filter 2 has a filter body 15 equipped with a rotary part 14 and a chamber 16 which houses the filter body 15. The rotary part 14 has a liquid chamber 27, a membrane filter 26 detachably provided in the liquid chamber 27, and a drainage part 42 that discharges a filtrate produced by the membrane filter 26. The centrifugal filter 2 further has a liquid cooling mechanism 44 in the rotary part 14 before filtration by the membrane filter 26. The cooling mechanism 44 preferably has a first external communication hole 39 located above the rotary part 14 to communicate with the outside of the chamber 16 and a second external communication hole 40 located below the rotary part 14 outside the first external communication hole 39 in a radial direction of the rotary part 14 to communicate with the outside of the chamber 16.SELECTED DRAWING: Figure 2 【課題】連続運転の際に遠心ろ過器の内部の温度上昇を抑える。【解決手段】遠心ろ過器２は、回転部１４を備えたろ過器本体１５と、ろ過器本体１５を収容するチャンバ１６と、を有している。回転部１６は、液室２７と、液室２７に取り外し可能に設けられたろ過膜２６と、ろ過膜２６でろ過されたろ過液を排出する排水部４２と、を有している。遠心ろ過器２はろ過膜２６でろ過される前の回転部１４内の液体冷却機構４４をさらに有している。冷却機構４４は好ましくは、回転部１４より上方に位置しチャンバ１６の外部と連通する第１の外部連通孔３９と、回転部１４より下方かつ第１の外部連通孔３９より回転部１４の半径方向外側に位置しチャンバ１６の外部と連通する第２の外部連通孔４０と、を有している。【選択図】図２
