Abstract

An under-sink waste processing appliance includes a waste separator which extracts liquid from organic waste and passes such extracted liquid to a residential drain line. The remaining solid, in the form of organic pulp, is dried in a dryer and deposited in a removable collection receptacle.

Claims (30)

1. An apparatus for processing organic waste from a sink positioned in a countertop, comprising:

a waste separator comprising (i) a first waste inlet coupled to a drain of the sink, (ii) a second waste inlet coupled to a waste-receiving slot located in the countertop, (iii) a motor-driven cutter operable to cut organic waste received through the first waste inlet and the second waste inlet, (iv) a liquid outlet for dispelling liquid extracted from organic waste during operation of the motor-driven cutter, and (v) a pulp outlet for dispelling pulp extracted from organic waste during operation of the motor-driven cutter, the pulp outlet being fluidly isolated from the liquid outlet,

a dryer comprising (i) a pulp inlet coupled to the pulp outlet of the waste separator, (ii) a drying chamber positioned to receive pulp advanced through the pulp inlet, (iii) a heating element operable to heat and dehydrate pulp positioned in the drying chamber to generate dried solid waste, and (iv) a dried waste outlet for dispelling dried solid waste from the drying chamber, and

a removable collection receptacle positioned to receive dried solid waste expelled from the dried waste outlet of the dryer.

2. The apparatus of claim 1 , wherein the motor-driven cutter comprises an augur.

3. The apparatus of claim 1 , wherein the motor-driven cutter comprises one or more centrifugal cutting disks.

4. The apparatus of claim 1 , wherein the dryer is operable to generate powder waste.

5. The apparatus of claim 1 , wherein the liquid outlet of the waste separator is configured to be coupled to a residential drain.

6. The apparatus of claim 1 , wherein the waste separator further comprises a filter to prevent pulp from escaping the waste separator through the liquid outlet during operation of the motor-driven cutter.

7. A domestic kitchen assembly, comprising:

a kitchen sink positioned in a countertop, the kitchen sink having a drain,

a faucet operable to fill the kitchen sink with water,

a waste separator comprising (i) a first waste inlet coupled to the drain of the kitchen sink, (ii) a second waste inlet coupled to a waste-receiving slot located in the countertop, (iii) a motor-driven cutter operable to cut organic waste received through the first waste inlet and the second waste inlet, (iv) a liquid outlet for dispelling water from the kitchen sink and liquid extracted from organic waste during operation of the motor-driven cutter, the liquid outlet being configured to be coupled to a drain, and (v) a pulp outlet for dispelling pulp extracted from organic waste during operation of the motor-driven cutter, the pulp outlet being fluidly isolated from the liquid outlet, and

a dryer comprising (i) a pulp inlet coupled to the pulp outlet of the waste separator, (ii) a drying chamber positioned to receive pulp advanced through the pulp inlet, (iii) a heating element operable to heat and dehydrate pulp positioned in the drying chamber to generate dried solid waste, and (iv) a dried waste outlet for dispelling dried solid waste from the drying chamber.

8. The kitchen assembly of claim 7 , further comprising a removable collection receptacle positioned to receive dried solid waste expelled from the dried waste outlet of the dryer.

9. The kitchen assembly of claim 7 , wherein the motor-driven cutter comprises an augur.

10. The kitchen assembly of claim 7 , wherein the motor-driven cutter comprises one or more centrifugal cutting disks.

11. The kitchen assembly of claim 7 , wherein the dryer is operable to generate powder waste.

12. The kitchen assembly of claim 7 , wherein the waste separator further comprises a filter to prevent pulp from escaping the waste separator through the liquid outlet during operation of the motor-driven cutter.

13. A method for processing organic waste from a kitchen sink positioned in a countertop, comprising:

advancing organic waste through a drain of the kitchen sink and into a waste separator positioned below the kitchen sink,

advancing organic waste through a waste receiving slot located in the countertop and into the waste separator,

operating a motor-driven cutter positioned in the waste separator to generate pulp and a separated liquid from the organic waste,

advancing the pulp from the waste separator to a dryer,

draining the separated liquid from the waste separator to a drain via a fluid path which bypasses the dryer, and

heating the pulp in the dryer to form a dried solid waste.

14. The method of claim 13 , further comprising advancing the dried solid waste into a removable collection receptacle positioned below the dryer.

15. The method of claim 13 , wherein heating the pulp comprises heating the pulp in the dryer to form solid waste powder.

16. The method of claim 13 , wherein operating the motor-driven cutter comprises operating an augur to cut and squeeze organic waste to separate liquid therefrom and generate the pulp.

17. The method of claim 13 , wherein operating the motor-driven cutter comprises operating one or more centrifugal cutting disks to cut and squeeze organic waste to separate liquid therefrom and generate the pulp.
