Solid-Liquid Extraction Pilot Plant Teaching Equipment

SL Solid-Liquid Extraction Pilot Plant Teaching Equipment

This unit enables to study countercurrent solid-liquid extractions in a continuous extractor with Archimedean screw.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Calculation of the number of theoretical stages
• Study of the extraction performance versus the nature and flow rate of the solid, and the type, flow rate and temperature of the solvent
• Extraction of oil from soybean laminate with hexane
• Extraction of chorophyl from spinach with ethanol
• Extraction of oil from olive husk with hexane
• Extraction of starch from potatoes with water
