The present invention relates to methods of drying and recovering toner
particles from a liquid carrier. The methods are very effective to
generate discrete, substantially non-agglomerated dry toner particles in
a manner that preserves the particle size and particle distribution of
the wet particles. The resultant dried toner particles free-flowing with
a relatively narrow particle size distribution. The present invention
uses extrusion techniques to coat wet toner particles onto a substrate
surface. Because the resultant coating has a relatively large drying
surface area per gram of particle incorporated into the coating, drying
may occur relatively quickly under moderate temperature and pressure
conditions. After drying, the dried toner particles are readily recovered
and may then be used in dry or even wet toners for electrophotographic
applications.
