Rising Film Evaporator

The Rising Film Evaporator, to study the operating processes of a rising film evaporator. It allows the monitoring of all the variables for a complete study of the process according to the working conditions and to investigate the effects of the variation of process parameters such as: vacuum, temperature, flow, etc. in the rising film evaporation.

A single tube-in-jacket evaporator that replicates industrial units which often contain scores of much longer tubes within the steam space. The component parts of the industrial process have been scaled down, feed tank, vapour/liquid separator, condenser, concentrate tank, condensate tank, CIP pump and vacuum pump, all manufactured from hygienic materials such as stainless steel, PTFE and glass.
