Vacuum evaporator with scraper system

Vacuum evaporator with scraper system

Overview

A thickening vessel fitted with a scraper is used to increase the concentration of extracted solutions by means of evaporation under vacuum. Extremely precise level measurement is required in this process because the concentration is determined by the filling height. The evaporation system operates according to meeting specified levels. As soon as they reach the correct value, the evaporation process is stopped and the concentrated solution is discharged out of the tank.
