Vacuum Evaporator

Vacuum concentration of food and biological products: apple juice concentration, sweetened condensed milk production, tomato sauce concentration, fermentation broth concentration. Pedagogical Objectives: Establish a mass balance on the evaporator. Establish a heat balance on the condenser. Learn about Vacuum Evaporator suppliers for optimal educational outcomes.. Study the influence of pressure and agitation speed on evaporation time. Study the influence of pressure on product boiling point. Learn about Vacuum Evaporator specifications for optimal educational outcomes.. Calculate heat transfer coefficients for conduction in an agitated tank.

Technical Description: The laboratory unit is presented on a wheeled platform. It consists of:
