Single effect evaporator contained a single vertical cylinder. In the centre of the cylinder there is a steam heating section, with pipes passing through it in which the evaporating liquors rise. At the top of the cylinder, there are baffles, which allow the vapours to escape but check liquid droplets that may accompany the vapours from the liquid surface.
Short tube (batch) evaporator used for final concentration of syrup. In glucose making companies carbon treated & pre-concentrated glucose syrup is passed through single effect evaporator to obtain 85~86% solids glucose syrup. This happens under vacuum and vapor is extracted and condensed in a barometric condenser. This range of evaporator is tailor-made to fit the plant capacity.
