CARBONIZED WOOD MANUFACTURING APPARATUS USING A DOUBLE HEATING METHOD WHICH INCLUDES PROCESSES OF HEATING AIR FIRSTLY FROM AN INNER CASE, AND SECONDLY IN BETWEEN THE INNER CASE AND AN OUTER CASE
PURPOSE: A carbonized wood manufacturing apparatus using a double heating method is provided to increase the temperature of air with the small amount of heat by expanding a contact time and a contact area of the air heated from the double heating method with an inner case.;CONSTITUTION: A carbonized wood manufacturing apparatus comprises the following: a furnace(10) heating air in the inside of a main body using a burner(12); a cylindrical inner case(14) in which the internal space is heated by the burner; a cylindrical outer case(11) sealed with an outlet in one end and separately located with the outside of the inner case while including the inner case in the inside; a screw(13) located in between the outside of the inner case and the inside of the outer case, in which one end is combined to the outside of the inner case; and a heat-gathering case(20) collecting the air heated from the inside of the inner case and returning the air to the inside of the outer case.;COPYRIGHT KIPO 2010
