Developed by Beau Dobson, the Dartmoor Dragon is a compact retort that can produce between 18 and 25kg of high quality charcoal per cycle depending of the feedstock used. Two cycles a day is typical with three possible. Ideally suited to smaller feedstock such as hedge laying arisings and smaller diameter branchwood, this machine can turn waste into income. It uses and oil barrel as a retort chamber—these barrels last around 30 cycles as they live in a fairly oxygen free environment when the machine is running. Hot barrels are removed safely and quickly with the lifting arm supplied and when placed in a sandpit or similar to cool, can be opened after a few hours. This machine is fairly light and easy to move.
