TASTE evaporators were invented in the 1960’s in order to improve the flavor of concentrated orange juice. Most of the evaporators in service at this time were of the forced re-circulation type and the concentrated product was of inferior quality and had burned or cooked flavors. TASTE is an acronym for Temperature Accelerated Short Time Evaporator and its innovation was to reduce the temperature and amount of contact time that the juice spent in this thermally abusive environment.

In this paper, the authors would like to explore two different but complementary issues concerning evaporators. One discussion concerns streamlining the process and operation of evaporators in order to gain multiple benefits in a plant environment. The other is to discuss new control technologies, specifically “Advanced” or Model Predictive Control and its application to automated °Brix control.
