The continuous biochar kiln makes biochar from biomass. The continuous biochar kiln is continuously operated by using an updraft fire through a vertical rotating fire tube. The rotary fire tube is attached to a blade that acts as a conveyor or mixer. The blade conveys the biomass from the inlet to the outlet of the cylinder shape and air-tight kiln. As the biomass is conveyed it receives the heat transfer from the vertical rotating fire tube wherein the biomass transforms into biochar at the outlet valve through the process of pyrolysis. The pyrolysis combustible gas may be generated during the process and that gas becomes the thermal energy to continue fueling the kiln.
