Abstract

The present disclosure relates to a drying apparatus for a powder raw material for manufacturing a secondary cell with an electric heater. In an embodiment of the present disclosure, a plurality of independently controlled heaters are mounted on a main body of an apparatus in which a plurality of heating regions are defined, and the temperature deviation of the internal chamber can reduce by providing the amount of heat supplied to each heating region through the control of the plurality of heaters. The main body of the apparatus includes a cylindrical portion in which the powder raw material is accommodated and sidewalls on both sides of the cylindrical portion, and by installing heaters on the cylindrical portion and the sidewalls, respectively, the entire region defining the main body of the apparatus can be evenly heated.

• F26B 9/08 - Machines or apparatus for drying solid materials or objects at rest or with only local agitationDomestic airing cupboards in stationary drums or chambers including agitating devices
• F26B 3/20 - Drying solid materials or objects by processes involving the application of heat by conduction, i.e. the heat is conveyed from the heat source, e.g. gas flame, to the materials or objects to be dried by direct contact the heat source being a heated surface
• F26B 3/24 - Drying solid materials or objects by processes involving the application of heat by conduction, i.e. the heat is conveyed from the heat source, e.g. gas flame, to the materials or objects to be dried by direct contact the heat source and the materials or objects to be dried being in relative motion, e.g. of vibration the movement being rotation
• F26B 9/06 - Machines or apparatus for drying solid materials or objects at rest or with only local agitationDomestic airing cupboards in stationary drums or chambers
