Rising Falling Film Evaporators
The Buflovak Rising Falling Evaporator or Concentrator (RFC) delivers high tube velocities which assures uniform product distribution and high coefficients of heat transfer. These concentrators are suitable for evaporating liquids that are heat sensitive and require minimum process time, pure or non-crystal forming, low to medium viscosities, foamy, and those containing fine suspended solids.
Product Details
The rising falling film evaporator (RFC), or recirculating version (RRFC), works on uniform metered flow entering the bottom of the steam chest and rises through the first pass with rapidly increasing velocity. After leaving the first pass the flow of the vapor liquid mixture is reversed and directed downward through the second pass at extremely high velocity. The mixture then enters the separator where the vapor and liquid are separated.
When not designed as a circulation unit, the rising falling film evaporator provides once through evaporation of heat sensitive materials, requiring minimum retention time. It is particularly adaptable to multiple effect systems but provides a lesser turn-down capability than the RRFC configuration.
