ABSTRACT:
A juice extractor device comprises a juice extractor body having a horizontally disposed slightly conical internal bore and a rotary body mounted in said bore. The juice extractor body includes a material inlet port on the upper side of the base end of the extractor body, a juice discharge port along the lower side of the extractor body, and a residuum discharge port on the upper side of the outer end of the body, and each port communicates with the bore. The juice discharge port includes a filter whose inner surface has a curvature equal to that of the bore surface. The rotary body is disposed adjacent all the ports and comprises an outer circumferential surface which has a spiral compressing portion confronting the two discharge ports and a spiral blade confronting the inlet port. The spiral compressing portion comprises a spiral wing and a valley therealong. The spiral blade, which is continuous with the spiral wing, also comprises a valley therealong. The gap between the valley of the spiral compressing portion and the surfaces of the bore and the filter is not more than 6 mm along a major portion of the spiral compressing portion. The gap between the spiral wing and the aforementioned surfaces is not more than 2 mm. These gaps each decrease in size in the direction preceding from the material inlet port toward the residuum discharge port.
