Partial or whole food hopper, grinder and cold press counter-top juicing machine, system and method

1. A method of cold press juicing comprising:

providing a pressing chamber configured to be removably attached to a frame of a juicing machine, the pressing chamber comprising a first pressing wall and a second pressing wall;

placing a disposable filter into the pressing chamber between the first and second pressing walls;

moving a lid unit to an open position, the lid unit comprising a collar and a pusher;

engaging the pusher with a lock on a chute, wherein the engagement between the pusher and the lock maintains the lid in the open position;

delivering food pieces into the chute attached to a grinder;

operating the grinder to reduce the food pieces into a reduced food mass;

directing the reduced food mass into the disposable filter in the pressing chamber; and

causing one or both of the first and second pressing walls to move toward each other and thereby press juice from the reduced food mass in the disposable filter.

2. The method of claim 1 , wherein engaging the pusher with the lock on the chute comprises placing a head of the pusher in a notch on an upper edge of the chute.

3. The method of claim 1 , wherein the engagement between the pusher and the lock maintains the pusher in a position above the chute.

4. The method of claim 1 , further comprising automatically directing, when the pusher is engaged with the lock on the chute, drips of liquid on a head of the pusher into the chute.

5. The method of claim 1 , further comprising:

disengaging the pusher from the lock;

moving the lid unit to a closed position; and

pushing, with the pusher, the food pieces in the chute toward the grinder.

6. The method of claim 5 , wherein disengaging the pusher from the lock comprises lifting the pusher out of the lock.

7. The method of claim 1 , wherein the lock comprises a notch on an upper edge of the chute.

8. The method of claim 1 , further comprising supporting with the pressing chamber, while the first pressing wall is in a retracted position, the disposable filter on all sides except a top, wherein in the retracted position an outlet of a grinder housing of the grinder is unobstructed by the first pressing wall.

9. The method of claim 1 , further comprising:

moving the grinder and the chute to an upper position before placing the disposable filter into the pressing chamber; and

moving the grinder and the chute to a lower position before operating the grinder, wherein in the lower position the chute is in communication with an inside of the disposable filter.

10. A method of cold press juicing comprising:

providing a juicing machine comprising a pressing chamber, frame, grinder, and a chute, the pressing chamber configured to be removably attached to the frame of the juicing machine, the pressing chamber comprising a first pressing wall and a second pressing wall;

moving, relative to the first pressing wall, the grinder and the chute from a lower position to an upper position;

placing a disposable filter into the pressing chamber between the first and second pressing walls;

moving, relative to the first pressing wall, the grinder and the chute from the upper position to the lower position;

delivering food pieces into the chute attached to the grinder;

operating the grinder to reduce the food pieces into a reduced food mass;

directing the reduced food mass into the disposable filter in the pressing chamber; and

causing one or both of the first and second pressing walls to move toward each other and thereby press juice from the reduced food mass in the disposable filter.

11. The method of claim 10 , further comprising supporting with the pressing chamber, while the first pressing wall is in a retracted position, the disposable filter on all sides except a top, wherein in the retracted position an outlet of a grinder housing of the grinder is unobstructed by the first pressing wall.

12. The method of claim 10 , further comprising removing the removable pressing chamber from the frame.

13. The method of claim 10 , further comprising automatically stopping operation of the grinder in response to detecting, with a sensor, that a lid unit attached to the chute is in an open position.

14. The method of claim 10 , wherein operating the grinder comprises:

rotating a plate relative to a cutter ring about an axis of rotation, the plate and cutter ring positioned in a housing; and

ejecting a portion of the food pieces radially outward, relative to the axis of rotation, and toward a side wall of the housing.

15. The method of claim 10 , further comprising passing the juice through a plurality of fluid passages in at least one of the first and second pressing walls.

16. The method of claim 10 , further comprising:

moving a lid unit to an open position, the lid unit comprising a collar and a pusher; and

engaging the pusher with a lock on the chute, wherein the engagement between the pusher and the lock maintains the lid in the open position.

17. The method of claim 10 , wherein the pressing chamber is configured to be positioned in the frame of the juicing machine.

18. The method of claim 10 , wherein the pressing chamber is configured to be removably attached to the frame with handles that sit upon opposite side plates of the frame.

19. The method of claim 10 , further comprising supporting the pressing chamber above a surface upon which legs of the frame are placed.

20. The method of claim 10 , wherein the pressing chamber further comprises opposite side walls, a bottom wall, and an open top located opposite bottom wall, and wherein the method further comprises fitting the pressing chamber together as a stand-alone unit.
