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: Apparatus for separating the juice and pulp of fruit or vegetable material comprises a base incorporating a drive mechanism, a case attached to the base and having a conical bore with the axis thereof extending horizontally between end walls of the case, a rotary member rotatably mounted in the case and driven by the drive member, the rotary member comprising a cutting blade portion and a pressing portion. The case is provided on its upper side near the wide end of the bore with a material inlet opening, on its lower side with a liquid outlet opening having a filter therein, and on a lateral side near the narrow end of the bore with a residual solids outlet opening. The cutting blade portion is spiral and has portion disposed near and confronting the material inlet opening. The pressing portion is conical (but oppositely disposed to the conical bore) and has portions disposed near and confronting both the liquid outlet opening and the residual solids discharge opening.

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.
