The Scraper series of vacuum evaporators have vertical development with the boiling chamber in the lower part with outer shell, while the condensation chamber is positioned laterally with an internal heat exchanger. The vacuum system guarantees minimum energy expenditure. The presence of an internal scraper allows constant cleaning of the internal walls and amalgamation of the treated product. The distance between the free surface of the effluent being treated and the collection plate guarantees the absence of drag out. and therefore a higher purity in the distillate.
