This system adopts internal heat type pyrolysis technology. The main body of the carbonization machine is a horizontal rotary kiln. The countercurrent process is adopted. The temperature of the carbonization zone is controlled at around 900°C. The company's patented technology is built in to ensure carbonization thermal efficiency and at the same time to ensure the quality of carbonization. Equipped with a wireless temperature sensing device to reflect the temperature of each point in the furnace in time to facilitate timely adjustment of the heat supply.
