NOVELTY - A machine made charcoal manufacturing method comprises: (a) sieving raw material; (b) sending the wood dust; (c) manufacturing the wood dust; (d) stacking the semi product obtained in (c); and (e) carbonization.    USE - The process is useful for manufacturing machine made charcoal (claimed).    DETAILED DESCRIPTION - A machine made charcoal manufacturing method comprises: (a) sieving raw material, taking deep processed wood dust, saw dust as raw material, centrifugally sieving to get rid of tree bark, branch and other rough impurity; (b) sending the wood dust, saw dust sieved in (a) in drying system, drying at 250 degrees C, the water content of the wood dust and saw dust should not surpass 10% in order to manufacture and form in the next process; (c) manufacturing the wood dust, saw dust obtained in (b) to be semi product by bar forming machine, before manufacturing and forming bar, heating temperature in the bar forming machine should be lower than 180 degrees C so as to ensure qualified product bar; (d) stacking the semi product obtained in (c), drying and waiting for charging and charring; and (e) carbonization, putting the dried semi product obtained in (d) in gasification decomposing furnace, igniting lower layer of gasification decomposing furnace filled with fuel bar, closing the ignition hole after it is ignited and sealed tightly, opening the air inlet, starting draught fan, after the fuel in the gasification decomposing furnace is burned sufficiently, blocking the gland bus, meanwhile opening the gasification furnace until carbonization furnace dissolves air transmission valve, igniting lower layer gas of the carbonization furnace, after the lower layer of the carbonization furnace burns sufficiently, starting carbonization furnace draught fan to discharge water contained in the saw dust bar, when the temperature of the furnace raises to 200 degrees C, after the burning time reaches 5 hours, water discharging is finished, starting carbonization furnace discharge air valve, carbonization furnace heats up gradually, the decomposed methane and carbon monoxide can be discharged, after igniting, the produced combustion and heat energy are sufficiently burned, they can be used in drying raw material, when the temperature in the carbonization furnace raises to 400 degrees C, close the gas discharge valve, form machine bar in the furnace enters in carbonization dry distillation state, when the temperature raises to 500 degrees C, restart the discharging air valve, after the gas (methane and carbon monoxide) in the carbonization furnace is released completely, close the valve, the carbonization is finished, naturally coo to obtain the charcoal.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the machine made charcoal manufacturing method (Drawing includes non-English language text).
