Apr 07, 2022 A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus (Figure 5.66a), and rotated while the system is partially evacuated (by a water aspirator or vacuum pump). The reduced pressure in the apparatus causes the solvent to boil at a lower temperature ...

5 Innovative Applications of Industrial Rotary Evaporators

Mar 26, 2021 They are typically used to remove solvents from a sample of a mixture of chemical compounds. Industrial rotary evaporators use a vacuum to lower a compounds boiling point whilst the sample is heated. This allows the solvent to be vaporized at a lower temperature than the standard boiling point. Industrial rotary evaporators have many uses and ...

Boiling Point And Surface Area: Detailed Facts

Boiling Point And Surface Area: Detailed Facts

The boiling point increases as the surface area of the molecular compound increases. This means that when the number of carbon increase in a linear chain the boiling point also increases with it. When branching takes place in the compound, it is then the boiling point reduces. The increase in boiling point due to surface area happens due to ...

Evaporators Dairy Processing Handbook

The circulation evaporation process line is shown in Figure 6.5.3. The milk is heated to 90 C and enters the vacuum chamber tangentially at a high velocity and forms a thin, rotating layer on the wall surface (Figure 6.5.2). As it swirls around the wall, some of the water is evaporated and the vapour is drawn off to a condenser.

This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process much more efficient.
