The TASTE evaporator is a single pass with multiple effects and stages. The number of effects ... evaporator each effect will do approximately 20% of the total water removal. When the juice is ... the caustic solutions. On citrus juice, evaporators need to be cleaned when small flakes of hesperidin start to ...
mistake conceptual problem with the design of the evaporator. The conceptual flaw is the assumption that the compressors, with an increase of the mass. flow rate to each stage tube bundle, the total energy of the stage will increase with the mass flow. rate to each stage tube bundle.
Evaporation is the removal of solvent as vapor from a solution. It is the operation which is used for concentration of solution. There could be single effect evaporator or multiple effect evaporators. With addition of each effect steam economy of the system also increases.
Plate Stripping and Evaporation Systems; Caustic and Other Specialized Concentration Systems; Distillation Equipment; ... A number of high efficiency configurations including multiple effect, thermal vapor recompression, and mechanical vapor recompression systems are employed and explained below: ...

If a single evaporator is used for the concentration of any solution, it is called a single effect evaporator system and if more than one evaporator is used in series for the concentration of any solution, it is called a multiple effect evaporator system.
Caustic Recovery for Mercerizing Units; ... Use of falling film evaporator with multiple effects ensures high energy efficiency is ideal for concentration of heat sensitive products, with low scaling tendency. ... with higher solids. This is also used as evaporative crystallizer. Sometimes these are used in series with falling film evaporator ...
Multiple effect Evaporator capacity and steam economy. ... When the solution being evaporated has a significant boilingpoint rise, the capacity obtained is very much reduced, for the boilingpoint rise reduces the ∆t in each effect. Calculations for multiple effect evaporators.
Superficially, the design of multieffect evaporators appears deceptively straightforward. Consider the most common situation in which water is the very volatile component and the other component is a solid (or has a very high boiling point).
FR MULTIPLE EFFECT EVAPORATION. Demand for soda ash increased and the supply of sodium sulfate had to increase in line. Therefore, in the nineteenth century, the large scale Leblanc process, producing synthetic sodium sulfate as a key intermediate, .
