Abstract
A solvent removing apparatus includes a container containing an emulsion comprising a first raw material of a continuous phase and a second raw material of a dispersed phase, an impeller rotating in the container to stir the emulsion, and a foam breaker spaced apart from the impeller on an upper portion of the impeller, positioned below a surface of the emulsion to be submerged in the emulsion when the emulsion is calm, and rotating to reduce foam generated during stirring of the emulsion.
