Figure 5.65: Rotary evaporator, water aspirator, condenser, and ice water circulator. Removal of solvent by a rotary evaporator is superior to evaporation under atmospheric pressure for many reasons. The process is much quicker (often takes less than 5 minutes), uses lower temperatures (so decomposition is unlikely), and uses less energy than boiling with a heat source.

For this example, a rotary evaporator is probably the most cost-effective choice. A large rotary evaporator capable of handling 16 liters/hour would recover the ethanol in about five and a half hours, which means that there would still be room for additional throughput on the extraction side; roughly, 17 pounds of additional feed material ...
