Technical Field

[0001] The utility model relates to the field of drying furnaces, in particular to an energy-saving blue charcoal drying furnace. Background Art

[0002] Lignite is a new type of carbon material made from high-quality Jura clean coal blocks that are abundant in the Shenfu coalfield. Due to the unique physical and chemical properties of lignite itself, there are lignite dryers on the market that are specifically used for drying lignite. This type of lignite dryer mainly uses a rotating tank body with a built-in heating element to turn and dry the lignite in the tank body.
