PIGNAT Solid Liquid Extraction – ESL1000


SKU: ESL1000 Category: Tags: ,


Study of discontinuous solid liquid extraction process.

This unit operation is used to extract a compound (solute) included in a solid phase using a liquid phase (solvent). The aim is to get a solid phase less concentrated in solute (residue) and an enriched liquid phase (extract).

Study solid-liquid extraction processes:

  • Percolation, decoction, infusion, maceration, digestion and elution
  • Steam extraction

Concentrate the extract by evaporation or distillation:

  • At atmospheric pressure
  • At reduced pressure

Proposed experiments:

Extraction from solid phases :

  • extraction of chlorophyll, caffeine
  • steam extraction
  • mass balance of the solute and the extract by sampling and analysis.
  • yield calculation and comparison depending on the operation parameters.
