Abstract
Disclosed are an apparatus for preparing a polymer latex resin powder in which an efficiency of mixing of steam, a latex, and a coagulant is increased by introducing a non-continuous screw into a reactor that performs coagulation and aging and thus a moisture content of a slurry is decreased and, accordingly, drying efficiency may be enhanced, and a polymer latex resin powder with excellent color and powder characteristics may be prepared using a decreased amount of coagulant and a method of preparing a polymer latex resin powder by using the same.
