Falling Film Evaporators

A 6-inch falling film evaporator listed at 60 L/hr for continuous solvent recovery, offered as Standalone, Pump Integration or Turnkey. Falling-film geometry spreads feed as a thin film down a heated body under vacuum, stripping solvent at a lower bulk temperature and shorter residence time than a batch still. Standalone is the column and frame, Pump Integration adds the process pumps, and Turnkey adds matched heating and cooling utilities. Pump models and a full packing list are not documented in the source data for this listing.

Two mirrored 6″ falling film evaporator columns on a single mobile frame, rated 79 to 158 L/hr on ethanol (20.8 to 41.6 GPH). Solvent evaporation efficiency runs 98% at 79 L/hr down to 85% at 158 L/hr. The turnkey scope includes a C1D1 crude feed pump at 60 L/hr and a C1D1 solvent recovery pump at 150 L/hr, with a CRH-300L heater and a 5x5H multi-stage chiller as the specified utility pairing. Jacketed lines, integrated cold traps and right-angle glassware keep tubing runs short in a compact footprint.

A 4″ falling film evaporator for continuous ethanol recovery, rated 12 to 25 L/hr (3.2 to 6.6 GPH). Solvent evaporation efficiency trades against rate: 98% at 12 L/hr, 95% at 14, 90% at 18 and 85% at 25 L/hr. Feed is spread as a thin film down a jacketed heated body under vacuum with VFD-controlled feed rate. Three configurations are listed: Standalone (evaporator body and frame), Pump Integration (adds a 60 L/hr crude feed pump, a 75-100 L/hr solvent recovery pump and a 21 CFM two-stage vacuum pump) and Turnkey (adds a CLC-50/40 chiller and CRH-50L heater).
