Juicing apparatus and juicing method

1. A juicer, comprising:

an inlet for receiving food items to be juiced;

a juice extracting arrangement for providing extracted juice;

a pulp collection area to collect pulp of the extracted juice;

a centrifuge unit for receiving the extracted juice and performing centrifuging to separate a juice component of the extracted juice from a foam component of the extracted juice, wherein the centrifuge unit comprises a chamber and an output gate for allowing the passage of the juice component, wherein the output gate comprises a blocking element that covers a chamber outlet of the chamber and defines a gap between an outer edge of the blocking element and an outer wall of the chamber to allow the juice component to pass through the gap before reaching the chamber outlet; and

an outlet for delivering the juice component.

2. The juicer as claimed in claim 1 , wherein the juice extracting arrangement comprises:

a centrifugal juicer;

a masticating juicer;

a triturating juicer; or

a blender.

3. The juicer as claimed in claim 1 , wherein the chamber receives the extracted juice, wherein the chamber further comprises a chamber inlet and the chamber outlet, and wherein the chamber outlet is set back from an outer portion of the chamber.

4. The juicer as claimed in claim 1 , wherein the juice extracting arrangement comprises a rotary juice extracting member, and a motor for driving the rotary juice extracting member.

5. The juicer as claimed in claim 4 , wherein the chamber is driven to rotate by the same motor.

6. The juicer as claimed in claim 5 , further comprising a gearing arrangement to drive the chamber and the rotary juice extracting member at different rotational speeds.

7. The juicer as claimed in claim 4 , wherein the chamber is driven to rotate by another motor.

8. The juicer as claimed in claim 1 , wherein the centrifuge unit is:

formed within a housing of the juicer; or

formed as a detachable attachment to the housing of the juicer.

9. The juicer as claimed in claim 8 and in which the centrifuge unit is formed within the housing of the juicer, wherein the juice extracting arrangement and the centrifuge unit share a common juice extraction chamber.

10. The juicer as claimed in claim 1 , wherein a centrifugal acceleration is at least 50 m/s 2 .

11. The juicer as claimed in claim 1 , wherein a centrifugal acceleration is in the range 200 to 900 m/s 2 .

12. The juicer as claimed in claim 1 , wherein the centrifuge unit comprises stirring blades.

13. The juicer as claimed in claim 1 , wherein the centrifuge unit comprises one or more modes of operation, and wherein the one or more modes of operations is selectable by adjusting the rotational speed of the chamber of the centrifuge unit.

14. A juicing method, comprising:

receiving food items to be juiced;

in a first stage of the juicing method:

providing extracted juice;

collecting pulp of the extracted juice in a pulp collection area;

in a second stage of the juicing method, performing centrifuging, in a centrifuge unit, to the extracted juice to separate a juice component of the extracted juice from a foam component of the extracted juice, wherein the centrifuge unit comprises a chamber and an output gate, wherein the output gate comprises a blocking element that covers a chamber outlet of the chamber and defines a gap between an outer edge of the blocking element and an outer wall of the chamber to allow the juice component to pass through the gap before reaching the chamber outlet; and

passing the juice component through an output gate to an outlet from which the juice component is delivered.

15. The method as claimed in claim 14 , comprising providing a centrifugal acceleration of at least 50 m/s 2 .
