Abstract

Embodiments of the invention provide a portable charcoal system and method of operating thereof, wherein the portable charcoal system comprises a first compartment adapted to burn a material, a second compartment connected to the first compartment and adapted to receive the material from the first compartment, and a third compartment adapted to receive the material from the second compartment, the third compartment comprising an auger adapted to move the material from a back end to a front end, and out of the third compartment. The portable charcoal system further includes a source of air.

First claim

We claim:

1. A method of continuously producing charcoal from a portable burn system, the method comprising the steps of:
initiating a combustion process of biomass within a burn compartment;
directing a stream of air from a source of air to at least one compartment of the portable burn system;
burning the biomass inside the burn compartment to produce an amount of charcoal;
transferring the amount of charcoal from the burn compartment to an extruding compartment through a collection compartment, wherein at least a portion of the charcoal is transferred through a portion of a bottom of the burn compartment to the collection compartment in which the bottom of the burn compartment is perforated; and
quenching and extruding the charcoal in the extruding compartment.

2. The method of claim 1 , wherein the method further comprises the step of cutting the charcoal into a pellet.

3. The method of claim 1 , wherein the charcoal is quenched with a heat conductive medium.

4. The method of claim 3 , wherein the heat conductive medium is water.

5. The method of claim 3 , wherein the heat conductive medium comprises at least one additive.

6. The method of claim 5 , wherein the at least one additive is selected from the group consisting of a fertilizer and a binder.

7. The method of claim 1 , wherein the method further comprises the step of drying the charcoal.

8. The method of claim 7 , wherein the charcoal is dried using heat generated in the step of burning the biomass inside the burn compartment.

9. The method of claim 1 , wherein the method further comprises the step of packaging the charcoal.

10. The method of claim 1 , wherein the biomass is selected from the group consisting of wood, slash, or chips.

11. The method of claim 1 , further comprising agitating at least a portion of the bottom of the burn compartment and transferring at least a portion of the charcoal through the agitated portion of the bottom of the burn compartment to the collection compartment.

12. The method of claim 11 , further comprising controlling the amount of charcoal transferred to the collection compartment by varying the amount of agitation applied to the bottom of the burn compartment.
