Which is the most suitable for the concentration of foamy & frothy liquors ?
Correct answer: D. Long tube vertical evaporator
- A. Agitated film evaporator
- B. None of these
- C. Open pan evaporator
- D. Long tube vertical evaporator
Explanation
A long-tube vertical evaporator is commonly used for foaming or frothy liquors because the rising vapor helps carry the liquid upward and provides effective vapor-liquid separation. Open pans give poor control and agitated-film units are mainly chosen for viscous or heat-sensitive liquids.
