Evaporator

Evaporator

The liquid to be treated is sucked in to the boiling chamber D01 as a result of the vacuum created inside it by the vacuum system. The feed is controlled by the level sensor LS01 which controls the pneumatic valve VP01. The bottom of evaporation chamber consists of a heating jacket heat exchanger E01. Inside the boiling chamber there is the scraper, driven by an electric motor-reducer M01.
The scraper shape assures a good cleaning of the heat exchanger E01 walls and an efficient stirring. The refrigerating fluid, coming from the heat pump circuit, flows in to the heat exchanger E01. The contact between the process liquid and the walls of the heating jacket leads to the boiling of the liquid it self. The vapor rises through the demister in order to damp the droplets.Vapor is condensed against the coil heat exchanger E03.

The vacuum system extracts the condensed distillate together with any incondensable gases and sends them to the storage tank D02. The distillate is discharged by overflow, then on-condensing gas are vented with the liquid. The concentrate is discharged through the valve V04 and by running of the membrane pump G02.
