Jumbo Rotary Film Evaporator

Rotary Film Evaporator is a very regular usage product in the R & D of chemical & Pharmaceutical industry. It is also being used nowadays for manufacturing purpose for high value pharmaceutical & specialty chemical products. The existing rotary film evaporators, which are used are with spherical evaporating flasks. What happens is when the requirement of volume for process it is practically very difficult to handle the size beyond 50 liters.
Chemical reactors are cylindrical in shape with a perticular LD ratio in general, which are given for a particular reaction surface area. The cylindrical vessel has a higher surface area spherical vessel. This prompted us to think in the direction; why only spherical vessel is used when we can exploit the advantage of cylindrical shape evaporation flask in a rotary film evaporator.
