A Simple and Inexpensive Evaporator Entrainment Separator

Use of angle iron separators in two evaporator vessels at Darnall resulted in a marked reduction in entrainment rates. Efficiencies in excess of 90% were observed with negligible pressure differential across the separator. Separator efficiency can be evaluated rapidly by using a centrally based Auto-Analyser. Introduction To avoid sugar losses by entrainment, all evaporator vessels are fitted w...
