PROBLEM TO BE SOLVED: To provide a device and a process for carbonizing biomass, which are carbonization technics for combustible wastes, particularly for biomass, generated in quantities on a small scale but irregularly, prevent or control the discharge of injurious materials such as dioxins on a small scale, and can produce a vegetable coal useful as fuel, a water cleaner and a soil conditioner that can be stored safely. SOLUTION: In the device for carbonizing biomass, a batch carbonization chamber 10, that carbonizes biomass by the heat generated in the chamber, is arranged in the lower part, and a gas combustion chamber 20, that causes to self-burn the gas stream containing volatile components discharged from the carbonization chamber 10, is arranged in the upper part, a temperature- sensing means 22, that detects the gas combustion temperature, being arranged in the gas combustion chamber 20, combustion air supply means comprising blowers 13 and 23 being respectively arranged in the carbonization chamber 10 and the gas combustion chamber 20, and a damper mechanism 31, that can isolate the carbonization chamber 10 from the gas combustion chamber 20, is arranged between the both chambers, the damper mechanism 31 being controlled by the power output of the temperature-sensing means 22.
