Lesson 1.5.1
Cold Ethanol Extraction: Full Procedure
Estimated time: 90 minutes
Learning Objectives
- ✓Execute a complete cold ethanol extraction from material preparation through crude oil collection
- ✓Know critical process parameters: solvent temperature (-40C target), contact time (under 20 minutes for selectivity), solvent-to-biomass ratio (typically 5:1 to 10:1 by weight)
- ✓Perform solvent recovery with a rotary evaporator or falling film evaporator
- ✓Identify and troubleshoot common problems: emulsions, excessive chlorophyll extraction, slow filtration, poor yields
- ✓Document the extraction in a proper batch record
