Abstract
A vacuum evaporator is provided with an integral cyclonic-type entrainment separator at the top of the evaporator vapor body which comprises a helical spin plate for imparting a centrifugal action to the vapor and entrained liquid rising from the boiling liquid in the flash chamber. Liquid entrainment is deposited on the vertical wall of the evaporator and flows downward countercurrent to vapor flow into a collecting trough, from which it is discharged into a pipe that returns it to the boiling liquid.
