Jumbo Rotary Film Evaporator

Jumbo Rotary Film Evaporator

The Jumbo Rotary Film Evaporator is an industrial-scale vacuum evaporation system developed to overcome the size, stability, and handling limitations of conventional spherical-flask rotary evaporators. Unlike traditional designs, this system uses a cylindrical borosilicate glass evaporation flask, enabling higher volumes, improved mechanical stability, and superior evaporation efficiency.

This innovation allows rotary evaporation to be scaled beyond 100 liters and up to 400 liters (extendable up to 800 liters) while maintaining safe operation, uniform thin-film formation, and efficient solvent recovery. It is ideally suited for pharmaceutical manufacturing, specialty chemicals, pilot plants, and high-value product processing.

Why Cylindrical Rotary Film Evaporator? (Design Innovation)

Traditional rotary evaporators rely on large spherical flasks, which become mechanically unstable, difficult to clean, and unsafe beyond 50 L capacities. The cylindrical evaporation flask solves these issues:

• Higher surface area compared to spherical flasks
• Lower diameter for the same volume → better pressure safety
• Horizontal drive → eliminates cantilever loading
• Axial support along flask length → reduced neck stress
• Easier product discharge and cleaning
• Safer handling for large glass volumesResult:
• Up to 20% higher evaporation rate
• Significantly improved mechanical stability
•  Enables true industrial-scale rotary evaporation

Working Principle

The Jumbo Rotary Film Evaporator works on the same vacuum evaporation principle as standard rotary evaporators, enhanced for scale:

• Product enters the rotating cylindrical glass flask
• Rotation creates a uniform thin film along the internal surface
• Vacuum lowers the boiling point of the solvent
• Controlled heating from a high-power SS heating bath
• Solvent vapors pass through high-efficiency glass heat exchangers
• Condensed solvent is collected in receiver flasks
• Concentrated product remains inside the cylindrical flask for easy discharge
