Abstract

A multi-food processor and juice extractor is provided that includes a container which houses a filter assembly. The assembly is operatively connected to a shaft for rotating the assembly within the container. The food is milled within the filter assembly by a plurality of cutters integral with the assembly, and after filtering, juice and/or particulate food matter is received from a juice outlet. Food dregs collecting along an inside wall of the filter assembly is removed by a stopper. A rotary control knob is provided to place the stopper into either an engaged or disengaged position. The stopper expels the dregs by utilizing centrifugal force created by the spinning filter assembly. A spring attached to the control knob automatically returns the stopper to the disengaged position upon releasing the control knob.

Claims

1. A multi-food processor and juice extractor for preparing processed food comprising:

a container having a removable cover for receiving food to be processed;

a filter assembly having an outer cylindrical wall and a bottom end, said assembly insertable within said container, said assembly including a milling means integral with said bottom end for reducing the food into smaller particulate food pieces and juice, and a filter element disposed around said outer wall for filtering the milled particulate food pieces and juice;

a rotation means connected to said filter assembly for rotating said assembly within said container;

a catch means in communication with said filter assembly for catching the particulate food pieces and juice filtered from said filter element;

a dregs removal means in operative engagement with said filter assembly for removing food dregs from said filter element after the particulate food pieces and juice have been filtered, said dregs removal means including a stopper means disposed within said assembly and movable along a radial direction from a disengaged position to an engaged position, and a rotatable control means attached to said stopper means for selectively moving said stopper to the engaged or disengaged position; and

an outlet port connected to said catch means for removal of the filtered particulate food pieces and juice.

2. An apparatus, as claimed in claim 1, wherein said dregs removal means further includes:

a plurality of dregs removal extensions protruding from said filter assembly and arranged in spaced relation thereto, said rotation means causing said dregs to be collected between said extensions when said stopper is in the engaged position

3. An apparatus, as claimed in claim 1, wherein said stopper includes:

an upper end and a lower end, said lower end being disposed at a vertical angle from said upper end in order to force dregs to be vertically raised along said cylindrical wall and to be collected between said extensions when said rotation means rotates said filter assembly.

4. An apparatus, as claimed in claim 1, further including:

a control switch operatively coupled with said rotation means for adjusting the speed of rotation of said rotation means.

5. An apparatus, as claimed in claim 1, wherein said catch means includes:

a sloping surface in communication with said outlet port such that particulate food pieces and juice flow by gravity force to said outlet port for removal.

6. An apparatus, as claimed in claim 1, wherein said milling means includes:

a support surface attached to said bottom end of said filter assembly; and

a plurality of cutting members protruding from said surface.

7. An apparatus, as claimed in claim 2, further including:

a dregs outlet in communication with said extensions along a portion of the path of rotation of said filter assembly such that when said dregs collect therebetween, the rotational force created by the rotation of said filter assembly causes the dregs to be forced radially away from said filter assembly into said dregs outlet.

8. Apparatus, as claimed in claim 1, wherein said rotatable control means includes:

a rotatable control knob; and

a biasing means operatively attached to said knob such that said biasing means provides a resisting moment against said knob when said knob is operated to move said stopper means to the engaged position, said biasing means causing said stopper means to return to the disengaged position when said knob is released.

9. A multi-food processor and juice extractor for preparing processed food comprising:

a container for receiving food to be processed;

a pusher connected to said container for pressing the food into said container;

a filter assembly disposed within said container, said assembly having an upper end, a lower end, and a cylindrical side wall, said upper end aligned to receive food to be processed, said cylindrical side wall having a filter element positioned therearound, said lower end having a milling means for reducing the food into smaller particulate food pieces and juice, said filter element filtering juice and passable particulate food pieces milled by said milling means;

a rotation means connected to said filter assembly for rotating said filter assembly within said container;

a catch means in communication with said filter assembly for catching the particulate food pieces and juice filtering through said filter element;

a dregs removal means in operative engagement with said filter assembly for removing food dregs from said assembly after the particulate food pieces and juice have been filtered, said dregs removal means including a stopper disposed within said assembly and movable along a radial direction from a disengaged position to an engaged position, a stopper support attached to said stopper for stabilizing said stopper within said assembly, and a rotatable control means attached to said stopper support for selectively moving said stopper to the engaged or disengaged position; and

an outlet port connected to said catch means for removal of the filtered particulate food pieces and juice.

10. Apparatus, as claimed in claim 9, wherein said rotatable control means includes:

a rotatable control knob; and

a biasing means operatively attached to said knob such that said biasing means provides a resisting moment against said knob when said knob is operated to move said stopper means to the engaged position, said biasing means causing said stopper means to return to the disengaged position when said knob is released.

11. A multi-food processor and juice extractor for preparing processed food comprising:

a container for receiving food to be processed;

a removable container cover having an upper and lower surface, said cover attachable to said container;

a pusher receivable over said cover for pressing food into said container;

a milling means in operative communication with said pusher for reducing said food into smaller particulate pieces and for extracting juice contained within the food;

a filter assembly attached to said milling means, said assembly and said milling means insertable within said container, said assembly having a cylindrical wall and a filter element disposed therearound for filtering the particulate food pieces and juice milled by said milling means;

a catch means in communication with said filter assembly for catching the filtered food and juice filtering through said filter element;

a rotation means coupled with said filter assembly and said milling means for rotation of said filter assembly and said milling means within said container;

dregs removal means in operative engagement with said filter assembly for removing food dregs from said filter element after said particulate food pieces and juice have been filtered, said dregs removal means including a stopper disposed within said filter assembly and movable along a radial direction from a disengaged position to an engaged position in near contact with said filter element, a stopper support attached to said stopper for stabilizing said stopper within said filter assembly, a stopper guide positioned on said bottom surface of said cover and in contact with said stopper support for channeling movement of said stopper in the radial direction, and a rotatable control means attached to said stopper support for selectively moving said stopper to the engaged or disengaged position; and

an outlet port connected to said catch means for removal of the filtered particulate food and juice.

12. Apparatus, as claimed in claim 11, wherein said rotatable control means includes:

a rotatable control knob; and

a biasing means operatively attached to said knob such that said biasing means provides a resisting moment against said knob when said knob is operated to move said stopper means to the engaged position, said biasing means causing said stopper means to return to the disengaged position when said knob is released.
