Multipurpose solid-liquid extraction process

Experimentation of different processes used in industries

Aroma extraction

This Solid-Liquid Extraction unit enables the solid-liquid extraction process to be implemented by simple contact in discontinuous mode. A certain quantity of solid matter (the load) containing the solute to be extracted is put in contact with the solvent (hot or cold). The unit is used in a batch process for small-scale operations in particular in the laboratory and for the extraction of cheap products of vegetal origin (extraction of chlorophyll, and caffeine, etc.) using aqueous or alcoholic solvents.

Study of different extraction processes:

  • In fixed bed or in suspension (infusion, percolation, decoction)
  • With solvent: liquid phase or steam

Extraction process:

  • Batch or semi continuous mode
  • Selection of the operating temperature and pressure
  • Extract and solvent phases recycling by forced or gravity flow

Evaporation process:

  • Batch or continuous mode
  • Selection of the operating temperature and pressure
  • Stripping with steam

Process Follow-up:

  • Mass and heat balances, process output
