Rocc Biochar Kiln

Basics

• An Abbreviation for ROtatable Covered Cavity
• A Design for a Charcoal Kiln that run in a Semi-Batch Manner that bridges the gap between smaller Charcoal Kilns and LARGE Rotary Kiln based plants
• 1 Ton - 10 Tons Biomass In Per 10 Hour Workday as per the video
• Made from a Steel Drum or a large Corrugated Steel Pipe (depending on desired scale)

Potential Improvements/Aspects to Explore

• Integration with a Narrow Gauge Railroad and/or Conveyor Belt + Loading Dock for Dump Trailers etc
• Improvements in "rollability" for lack of a better word, either Rack+Pinion, or even just Ball Bearing based Rollers such as those ripped off a Drum Dolly or Hand Cart
• Insulation/Refractory Coating?
• Design for Lifting ; add a bracket for a Crane Shackle on there
  • Could also integrate with an Overhead Crane this way
• An integrated trailer with the fuel in and fuel out ramps
• Motorization?
