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.

A liquid removal device is for removing a liquid from a surface. The liquid removal device includes a chassis comprising a handle and an absorber drum and an extractor drum both rotationally coupled with the chassis. The absorber drum includes a cylinder, where an absorbent layer is positioned on an outer drum surface of the absorber drum. The extractor drum includes a reservoir configured to retain the liquid absorbed from the surface, an outer extractor surface, and a plurality of apertures defined by the outer extractor surface in fluid communication with the reservoir. The extractor drum is movable between a first position and a second position. In the first position, at least a first portion of the plurality of apertures are in contact with the absorbent layer. In the second position, the first portion of the plurality of apertures are not in contact with the absorbent layer.

An electrostatic spray drying system comprising an electrostatic spray nozzle for directing electrically charged liquid into a drying chamber, a drying gas inlet from which drying gas is simultaneously directed, and a conical powder direction plenum for receiving drying gas and entrained dried powder for direction to a filter containing powder separation plenum via a connecting conduit. The powder direction plenum and connecting conduit each have a surrounding water jacket heat exchanger through which cooling water is directed for cooling the drying gas and powder below damaging temperatures prior to entry into the powder separation plenum. The powder separation plenum has a return line for redirecting separated drying gas to the drying chamber through a condenser, blower, and heater for reuse in the system, with condensed water being selectively redirected to the inlet of the powder direction plenum heat exchanger and/or to the cooling water supply.
