As above mentioned, because of small granularity and low water content (below 15%), you can feed rice hull into continuous biochar making furnace directly. Our industrial charcoal kiln uses Q245 R steel and 310S stainless steel as materials, which make the temperature inside the body reach 650℃. Under the action of high temperature, rice husk materials will convert to charcoal quickly, within 30 min. In addition, with double-layer design, it can make carbonized rice hull for you for 24 hours. Because it can carbonize rice husk and discharge finished charcoal simultaneously.
