Abstract: The method of manufacturing toners disclosed herein includes a continuous temperature ramp and coalescence process that involves continuously passing toner slurry, such as an aggregated toner slurry, through at least one heat exchanger before being subjected to a cooling step. The heat exchanger is pressurized, so the temperature of the slurry may be increased above the atmospheric boiling point of water without boiling the water component of the slurry. Because of these higher temperatures, the coalescence step can be completed more quickly than in conventional batch processes. More than two heat exchangers may be connected in the coalescence step, yielding multiple ramping/cooling temperature steps, ability to inject components, or recycling heat from the process to reduce energy consumption.
