Product Details

This apparatus is designed to study the operation and behavior of a climbing film evaporator, a critical device used in process and food engineering to concentrate temperature-sensitive solutions like milk by partially removing the solvent through evaporation. It allows students to investigate how heat transfer, steam pressure, and flow rates affect the concentration process, providing hands-on insight into industrial evaporation techniques. The system features a double-pipe heat exchanger evaporator heated by steam, with the steam pressure precisely regulated by a PID controller. The untreated solution is fed from a tank into the evaporator, where it forms a thin film and undergoes partial vaporization. The vapor-concentrate mixture then enters a cyclone for separation; the vapor is condensed in a water-cooled condenser and collected, while the concentrated solution can be either collected or recirculated for further concentration. The unit includes a 7-inch touch LCD and data acquisition software for real-time monitoring, control, and analysis of process parameters. Its primary applications are in chemical and food engineering education, where it demonstrates principles of heat transfer, mass balance, and evaporation dynamics. The key benefits are its ability to simulate real industrial processes safely, enabling students to optimize operational variables, understand energy efficiency, and analyze the impact of control parameters on product concentration, thereby bridging theoretical knowledge with practical skills essential for industries like dairy, pharmaceuticals, and chemicals.
