Abstract: Juice extractor comprising a rotary body having a rotary shaft supported therein in such a manner that the shaft can be rotated and axially moved, and a cover adapted to be screwed to a juice extractor body, the shaft being rotatable with the cover screwed to the juice extractor body, the shaft and cover being combined and rotated together when the latter is loosened, the rotary body being able to be drawn out easily from the juice extractor body.

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.

Abstract: Apparatus for separating the juice and pulp or residual matter of fruit or vegetable material comprises a case having a substantially conical bore. The case has a material inlet opening on the top which communicates with the wide end of the bore; a juice outlet opening (with a filter therein) on the bottom which communicates with the bore; and a residual matter outlet opening on one side which communicates with the narrow end of the bore. A motor-driven rotary member is rotatably mounted in the bore. The rotary member has a spiral cutting blade portion for cutting the material into pieces and a spiral pressing portion connected to the spiral cutting blade portion for pressing and squeezing the cut pieces to extract the juice therefrom. The rotary member cuts material entering through the inlet opening into pieces, and feeds the pieces toward the narrow end of the bore while squeezing the pieces to separate the juice and the pulp or residual matter.
