PROBLEM TO BE SOLVED: To obtain a screw type squeezing device capable of operating for a long time by shutting out the invasion of the outside air and moreover easily disassembling and washing without generating steam. SOLUTION: In the screw type squeezing device 21 provided with the tank 23 storing a solid and liquid mixing material, the natural filtering part 27 filtering and separating the liquid from the solid and liquid mixing material fed from the tank 23 integrated a rotatable and cylindrical filtering screen within a casing 39, and the dehydrating part 29 further separating the solid and liquid mixing material fed from the natural filtering part 27 into the squeezed and filtered liquid and solid using a spiral screw, the feeding nozzle discharging the solid and liquid mixing material fed from the tank 23 from the tip end is pierced into the casing 39 of the natural filtering part 27 and fixed. The filtering screw is rotatably supported by also using this feeding nozzle as the rotating shaft. |
