PROBLEM TO BE SOLVED: To provide a scum crusher that can prevent foreign substances, such as a screen residue, from twisting around a blade when the scum crusher is not operated and used.SOLUTION: A scum crusher 3 comprises: at least one belt-like or string-like blade 11 that is rotated in the vicinity of a liquid surface in a digestion tank body 1 (in a digestion tank 100) or at a position between the liquid surface in the digestion tank body 1 (in the digestion tank 100) and its ceiling part; an electric motor 12; and torque transmission means 13 that transmits the rotation of the electric motor 12. When the scum crusher 3 is not used, the blade 11 is stored inside a cylinder 18 disposed in a gas phase in the digestion tank body 1 (in the digestion tank 100) or evacuated to the outside the digestion tank body 1 (the digestion tank 100). 【課題】装置を動かさない未使用時に、し渣などの夾雑物が羽根に絡みつくことを防止することができるスカム破砕機を提供すること。【解決手段】消化槽本体１内（消化槽１００内）の液面付近または、消化槽本体１内（消化槽１００内）の液面とその天井部との間の位置で回転させられる帯状または紐状の少なくとも１枚の羽根１１と、電動機１２と、電動機１２の回転を羽根１１に伝達する回転力伝達手段１３と、を備えるスカム破砕機３である。未使用時に、消化槽本体１内（消化槽１００内）の気相部に配置された筒１８の中に羽根１１が収容される、または消化槽本体１（消化槽１００）外へ羽根１１が退避される。【選択図】図２Ａ
