Film Process Head Patents (Class 399/141)
  • Patent number: 11022913
    Abstract: Aspects presented herein are directed towards a carrier evaporator for a Liquid Electrophotography Printing (LEP) system. In an example, the carrier evaporator provides a hot air supply to absorb an evaporated carrier liquid resulting in first air flow comprising a carrier vapour, an evacuator to evacuate at least a portion of the carrier vapour, a heat exchanger to decrease a temperature of the remaining carrier vapour thereby transforming the first air flow to a second airflow comprising carrier particles, and a filter to remove the carrier particles from the second air flow.
