Multi-functional fecal waste and garbage processor and associated methods

1. A dryer assembly for drying material, the dryer assembly comprising:

first and second tubular shells respectively containing first and second hollow carriers that each defines a bore, each of the hollow carriers receiving a hollow auger in the bore thereof, the hollow augers being drivingly coupled to be driven in rotation by one or more drive motors;each of the first and second tubular shells comprising a steam inlet in fluid communication with an interior of the hollow carriers and an interior area of the hollow auger;a first transfer housing connecting the hollow carriers of the first and second tubular shells at first ends of the first and second hollow carriers and a second transfer housing connecting the hollow carriers of the first and second tubular shells at second ends of the first and second hollow carriers;an inlet open to the bore of the first hollow carrier near the first end of the first hollow carrier;one or more outlets formed in a side of the second hollow carrier,wherein the one or more drive motors are connected to drive the hollow auger of the first hollow carrier to convey material in a direction from the inlet toward the second end of the first hollow carrier and to drive the first and second hollow augers to carry material in the first and second hollow carriers in opposing directions.

2. The dryer assembly of claim 1 , wherein the material being dried is waste that comprises a mixture of water and solid waste material, and the first tubular shell has a first material path to carry the waste therethrough, and has a first steam path coupled to the steam inlet of the first hollow carrier and isolated from the first material path, wherein the first steam path is configured to use heat from steam in the first steam path to thermally separate at least a portion of the water of the waste in the form of waste steam from the solid waste material.

3. The dryer assembly of claim 2 , wherein the second tubular shell has a second material path and a second steam path, the second material path configured to receive partially dried waste from the first waste path of the first tubular shell, and the second steam path is adjacent to and isolated from the second material path, the second steam path receives at the steam inlet of the second tubular shell steam from the first hollow carrier, wherein heat from the steam received from the first hollow carrier thermally separates the water from the solid waste material of the waste in the second material path.

4. The dryer assembly of claim 1 wherein the hollow auger in each of the first and second tubular shells carry steam that is isolated from the material in the bore therein, wherein heat from the steam in the auger dries the material by thermally separating water from material being moved by the hollow auger in each of the first and second tubular shells.

5. The dryer assembly of claim 1 wherein the one or more outlets communicates with the internal area of the second hollow carrier and receives dried material that the second hollow auger conveys through the second tubular shell after water has been thermally separated from solids of the material conveyed through the first and second hollow carriers.

6. The dryer assembly of claim 1 wherein the first transfer housing is coupled to a waste infeed assembly configured to deliver waste material comprising a mixture of solid waste and water.

7. A dryer assembly for drying waste material having water and solid fuel material therein, the dryer assembly comprising:

first and second tubular shells respectively containing first and second hollow carriers that each defines a bore, each of the hollow carriers receiving a conveyance assembly in the bore thereof, the conveyance assemblies being drivingly coupled to be driven in rotation by one or more drive motors and configured to advance the waste material through the first and second tubular shells;each of the first and second tubular shells comprising a waste path and a steam path therein, each steam path having a steam inlet, and the steam path in each of the first and second tubular shells being isolated from the waste path therein and being in thermal communication with an interior of the tubular shell to heat the waste and thermally separate the water from the solid fuel material as the waste moves through the interior of first and second hollow carriers, and the steam path being in communication with an interior area of a hollow auger to heat the hollow auger in the respective first and second hollow carriers;a first transfer housing connecting the hollow carriers of the first and second tubular shells at first ends of the first and second hollow carriers and a second transfer housing connecting the hollow carriers of the first and second tubular shells at second ends of the first and second hollow carriers;an inlet open to the bore of the first hollow carrier near the first end of the first hollow carrier;one or more outlets formed in the second hollow carrier and positioned to receive dried solid fuel material after the water has been thermally separated therefrom,wherein the one or more drive motors are connected to drive the hollow auger of the first hollow carrier to convey material in a first direction from the inlet toward the second end of the first hollow carrier and to drive the first and second hollow augers to carry material in the first and second hollow carriers in different directions.

8. The dryer assembly of claim 7 , wherein heat from steam in the first steam path thermally separates the water from the solid fuel material of the waste material being conveyed through the first waste path, wherein the thermally separated water is waste steam, wherein the waste steam is directed into the second hollow carrier adjacent to the second waste path, wherein heat from the waste steam thermally separates the water from the solid fuel material of the waste material being conveyed through the second hollow carrier.
