Abstract

A food recycler can include a housing defining an interior and an access opening to the interior. A mixing bin can be located within the interior and can have an inlet and an outlet. The food recycler can further include an output bin, the output bin having an inlet. The outlet of the mixing bin can couple or connect to the inlet of the output bin.

First claim

What is claimed is:

1. A food recycler comprising:
a housing defining an interior and an access opening to the interior;
a mixing bin located within the interior and defining a mixing chamber having a first inlet accessible via the access opening and a first outlet;
an output bin defining an output chamber having a second inlet and a second outlet; and
a transfer assembly for transferring food waste from the mixing bin to the output bin comprising:
a mechanical vibrator configured to rotate and comprising a plurality of teeth and a side surface positioned orthogonal to the plurality of teeth;
a chute closed by a sidewall along at least a portion of its length and operably coupling the first outlet of the mixing bin to the second inlet of the output bin; the chute comprising a protruding element positioned on the sidewall of the chute and extending outwardly therefrom and resiliently bearing against the side surface of the mechanical vibrator;
wherein rotation of the mechanical vibrator causes the chute to vibrate in an up and down matter when the protruding element alternately engages and disengages with the side surface of the plurality of teeth.

2. The food recycler of claim 1 wherein at least a portion of the output chamber is directly below a portion of the mixing chamber.

3. The food recycler of claim 2 wherein the mixing bin comprises a cylinder with an open top defining the first inlet.

4. The food recycler of claim 2 wherein the first outlet is located in a side of the mixing bin and the second inlet is located in a top of the output bin.

5. The food recycler of claim 1 wherein the chute comprises a funnel portion and an open slide portion.

6. The food recycler of claim 5 wherein the funnel portion is proximate one of the first outlet or the second inlet and the open slide portion is proximate the other of the first outlet or second inlet.

7. The food recycler of claim 6 wherein the funnel portion is proximate the first outlet and the open slide portion is proximate the second inlet.

8. The food recycler of claim 7 wherein the first outlet is in one of a side or bottom of the mixing bin.

9. The food recycler of claim 8 wherein the second inlet is in one of the top or side of the output bin.

10. The food recycler of claim 9 wherein the second outlet is in a side of the output bin.

11. The food recycler of claim 1 further comprising an outlet door selectively closing the first outlet.

12. The food recycler of claim 11 wherein the outlet door is located between the chute and the first outlet.

13. The food recycler of claim 12 wherein the outlet door overlies a portion of the chute when the first outlet is open.

14. The food recycler of claim 1 further comprising a scraper operably coupled to the chute.

15. The food recycler of claim 14 wherein the scraper moves along at least a portion of the chute.

16. The food recycler of claim 14 further comprising an outlet door selectively opening/closing the first outlet by moving between opened/closed positions and the scraper is mounted to the outlet door such that the scraper moves along the chute toward the outlet door as the outlet door moves between the closed and opened positions.

17. The food recycler of claim 1 wherein the mixing bin further comprises a stirrer located within the mixing bin.

18. The food recycler of claim 1 wherein the chute is partially enclosed.

19. The food recycler of claim 1 wherein the plurality of teeth comprises alternating gaps between each tooth in the plurality of teeth.

20. The food recycler of claim 19 further comprising a compression spring for biasing the protruding element against the plurality of teeth.

21. The food recycler of claim 20 wherein upon rotation of the mechanical vibrator the compression spring biases the protruding element against the plurality of teeth and causes the chute to alternate between rising when the protruding element engages each tooth in the plurality of teeth and falling when the protruding element falls into the gap between each tooth.

22. The food recycler of claim 1 further comprising a mounting plate within the housing for mounting the chute.

23. The food recycler of claim 22 further comprising at least one vibration damper positioned between the mounting plate and the chute for allowing flexibility of the chute relative to the mounting plate.
