WIPO Patent Application WO/2015/046072
Kind Code:
A1
Abstract:
When a kneaded mixture, in which a binder-containing additive and water have been added to carbon powder and kneaded, is formed into a rod-shaped carbon heat source (HS) and the carbon heat source (HS) is subsequently dried to manufacture the finished product, the drying method according to the present invention: generates a dry atmosphere in which the evaporation rate (Vo) at which water evaporates from the outer surface of the carbon heat source (HS) is made to approach the velocity (Vs) of the water inside the carbon heat source (HS) moving toward the outer surface while the weight absolute humidity (AH) is decreased in a step-wise fashion; and dries the carbon heat source (HS) in the dry atmosphere.
