Selection logic, retrofit economics and mother-liquor yield — articles from three lines: technology deep-dives on evaporator and crystallizer selection, application solutions for specific wastewaters and process duties, and anonymized project case studies. New articles are published continuously.

Plate evaporator selection across seven parameters: capacity sizing with margin, falling-film vs forced-circulation plates, 316L/duplex/titanium corrosion grades, 30-65C vacuum window for actives, 1.8-2.5 m/s
Representative configuration of a complete tomato paste evaporation line in Northwest China (Xinjiang): four 1,500 t/d lines plus one 750 t/d line in triple-effect
Lecithin concentration and drying solutions from degumming to thin-film vacuum drying – capacities 3-150 t/d, four product grades, food-grade specs and the viscosity challenges
How industrial evaporation works: single-effect vs multiple-effect vs MVR energy performance, vacuum boiling, evaporator types by material behavior, and the concentration endpoint that hands
Representative configuration of a 4 t/h MVR rising film evaporator concentrating ejiao (donkey-hide gelatin) liquor in China, handling high-viscosity collagen solutions at low temperature
Crystallizing vitamin C (ascorbic acid) from concentrated fermentation-purification liquor is a crystal-size and stability problem: the product oxidizes in the presence of heat, air
