Falling Film Evaporators concentrate liquids by spreading the feed as a thin film down the inside of heated tubes, where gravity carries the film and the solvent boils off in seconds. Running under vacuum lowers the boiling point, and the short contact time protects heat-sensitive products such as fruit juices, dairy, herbal extracts and APIs from colour change or degradation. Evaporation capacity runs from 15 to 700 L per hour with continuous feeding and discharge, in glass for visibility and chemical resistance or in SS304 and SS316L for pilot and production work. Typical uses include solvent recovery, juice and sweetener concentration, extract processing and crystallisation.
