A pump, for example, is conceivable as a means for transferring the collected oil and scum to a waste container or the like, but this pump can suck high-viscosity fluid and air, and may be installed in the kitchen. Easy waterproofing is required. Screw pumps, tubing pumps (peristaltic pumps), and the like are known as pumps that satisfy such requirements. However, the screw pump has a problem that it is apt to be clogged when solid matter is mixed in, and the tubing pump can pump up a high-viscosity fluid or a fluid containing a solid matter, but a large solid matter or There is a problem that troubles are likely to occur when pointed materials, cloth, paper, etc. are mixed. On the other hand, large solids, sharp objects, cloth, paper, etc. are not mixed in the oil and scum collected by the oil and scum collecting device described above. Therefore, by combining the oil and scum recovery device and the tubing pump that transfers the recovered oil and scum to the disposal container, etc., the recovery of the oil and scum and the transfer of the recovered oil and scum can be performed manually. It can be automatically performed without any operation, and the collection work and the transfer work can be significantly reduced. The tube pump has a problem that the tube life is short because the tube is crushed and sucked, but the collected oil and scum is transferred to a waste container, etc. It may be performed when the inside of the recovery tank of the device is full. Therefore, when the inside of the recovery tank is full, for example, a predetermined time, the tubing pump is driven for a predetermined time. The life of the pump tube can be extended.
