As evaporation is an energy-intensive process, it is important that evaporators operate efficiently at their maximum capacity. The aim of this study was to compare the effectiveness of a pilot-scale, single-stage falling-film evaporator in the evaporation of water and skim milk. The solutions were fed at a boiling temperature of 60 °C, and a mass flow rate of 50.0 ± 0.7 kg·h−1. There was no significant variatio...
