Abstract
A continuous emulsion aggregation process for the production of particles is presented including a plurality of continuous stirred-tank reactors (CSTR). The plurality of continuous stirred-tank reactors includes a first reactor and a second reactor for facilitating an aggregation process; a third reactor for facilitating a shell addition process; a fourth reactor for facilitating a freeze process; a fifth reactor for facilitating a chelating process; a sixth reactor for facilitating a ramp-up process; and a seventh reactor for facilitating a coalescence process. The reactors are sequentially assembled in a series configuration, each of the reactors cooperating with an overhead stirrer. In other embodiments, a CSTR system of the present disclosure possesses five reactors sequentially assembled in a series configuration to form toner particles.
