SOLUTION: With regard to a feeder which kneads the raw material ground fish by a pump having screw shafts and pressurizes and delivers the ground fish as the pump, a pair of the screw shafts 14 and 14' which are different in pitch between raw material suction sides 15 and 15' and discharge sides 16 and 16'. Deaeration nozzles 17 and 17' are installed in a casing 11 of a pressure increasing place in the vicinity of the boundary between the suction side and the discharge side of each screw shaft 14 or 14', and the pump 20 for collecting bubbles and the raw material extracted together with the bubbles is installed outside a nozzle opening. A collecting course for returning the raw material collected by the deaeration nozzles 17 and 17' to the pump is provided. COPYRIGHT: (C)2006,JPO&NCIPI |
