Summary:The present invention relates to a secondary battery manufacturing powder raw material drying apparatus having an electric heater. According to an embodiment of the present invention, a plurality of independently controlled heaters are mounted at an apparatus main body in which a plurality of heating areas are defined, and an amount of heat supplied for each heating area is provided through control of the plurality of heaters. Therefore, temperature deviation of an interior chamber can be reduced. The apparatus main body includes: a cylindrical unit in which a powder raw material is accommodated; and side walls of cylindrical unit both sides. The heaters are installed on each of the cylindrical unit and the side walls. Thus, an entire area defining the apparatus main body can be evenly heated. 본 발명은 전기히터를 구비한, 이차전지 제조용 분말원료 건조장치에 관한 것이다. 본 발명의 실시예는, 다수의 가열영역이 정의되는 장치 본체에 독립적으로 제어되는 다수의 히터를 장착하고, 상기 다수의 히터의 제어를 통하여 가열영역별로 공급되는 열량을 제공함으로써 내부 챔버의 온도 편차를 줄일 수 있다. 상기 장치 본체는 분말원료가 수용되는 원통부 및 상기 원통부 양측의 측벽을 포함하고, 상기 원통부 및 측벽에 각각 히터를 설치함으로써 장치 본체를 정의하는 전체 영역을 고르게 가열할 수 있다.
