This process combines the two aforementioned processes.



  • Two different qualities of oil: 60% from cold pressing and 40% from hot pressing
  • Residual Oil content in the meal around 8%
  • Recycling of press sediments possible by progressively placing them into the cooker.



  • Higher investment (boiler
  • Energy consumption
  • Requires double filtration if there is a need for two different qualities of oil
  • Oil extracted from hot pressing: requires additional treatment (refinement or esterification)


As for the hot installation, the process is expensive and is not economically viable below a certain tonnage depending on the production site and the type of seeds treated.
