Rising Film Evaporation Pilot Plant Teaching Equipment

RFE Rising Film Evaporation Pilot Plant Teaching Equipment

Rising film evaporators can ensure a high heat-transfer coefficient and short residence time to the solution having to be concentrated.
They are used especially to concentrate thermosensitive products such as antibiotics, fruit juices, milk, etc…
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Mass balances
• Energy balances
• Evaporation operations on food liquids, organic solutions,
etc...
• How the following parameters affect the process:
- feeding flow rate
- vacuum degree
- recycling of the product
- flow rate/pressure of steam
• Overall heat transfer coefficient
• CIP (clean in place) procedures
