rotary kiln biochar

Mini-kilns, such as those made by Wilson Biochar Associates (www.wilsonbio-char.com) are ideal for small landowners interested in conservation stewardship or soil enhancement projects. These small kilns can be operated by one or two peo-ple. Depending on the type and size of kiln, processing can take hours to days to complete. Newer rotary kilns

Traditional kiln technology has been used to produce charcoal since ancient times. Numerous designs including traditional earth-mound kilns and brick-made kilns have provided charcoal for cooking, smelting and metalworking for millennia. That said in the context of making biochar kilns are usually open top to allow for more feedstock to be added

In an auger kiln, residence time can be controlled, but temperature is kept quite high to prevent tar build up within the auger. In a rotary kiln, temperature can sometimes be kept in a lower range, but residence time cannot be controlled. Hence both are unsuitable to produce a biochar with optimal soil fertility characteristics

This separates the biogas compounds from the biomass, leaving behind carbon-rich biochar. To accomplish this process, we decided to use a rotary kiln reactor sourced from Beston Machinery.Their clean and safe process will produce roughly a 33% yield of biochar with a capability of processing up to 3
