  • Patent number: 10989472
    Abstract: Disclosed is a method, apparatus and system of drying wet toner particles which includes the use of cooling fluid. The method also includes introducing a heated drying gas into a toner drying chamber to create a circulating flow of drying gas.
    Type: Grant

  • Patent number: 9329508
    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.

  • Patent number: 9182691
    Abstract: Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. An aggregated particle slurry is further heated in a first heat exchanger, and the heated slurry then flows through a residence time reactor. The slurry, now containing coalesced particles, then flows through a second heat exchanger and is quenched. The recovered coalesced particle slurry is then suitable for washing and drying. No moving parts are needed in this system.
