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 at least one feed tank of raw materials, at least one reactor for facilitating cold addition, at least two reactors for facilitating an aggregation process, at least one reactor for facilitating a shell addition process; at least one reactor for facilitating a freeze process, at least one reactor for facilitating a chelating process, at least one reactor for facilitating a ramp-up process and at least one reactor for facilitating a coalescence process, wherein the reactors are sequentially assembled in a series configuration and separated by short conduits to produce toner particles that are narrowly distributed.
