Rising film evaporator for concentration of viscous liquids
When dealing with the concentration of low-to-medium fouling or highly viscous liquids in various industries, a significant challenge arises in maintaining efficiency without compromising product quality or space requirements.
Concentrate process liquids with minimal space requirements
The Alfa Laval AlfaVap is a rising film evaporator designed to handle low-to-medium fouling and highly viscous liquids across numerous applications and industries. This system requires 50-70% less height compared to conventional shell-and-tube evaporators, making it easier to install in existing facilities. The AlfaVap offers fast start-up and shut-down times, high heat transfer efficiency, and a short residence time, which is crucial for heat-sensitive products. It achieves high energy efficiency by using multiple effects and thermal or mechanical vapour recompression units, resulting in lower steam usage. Maintenance is minimized thanks to its self-cleaning effect, driven by high turbulence and shear rates. Typical applications include sugar refinery, sweeteners, protein processing, bioethanol, and caustic evaporation tasks. The AlfaVap system includes all necessary components, from pumps and piping to control panels, and can be pre-assembled in Alfa Laval’s workshop to cut down on installation time.
Benefits
- Reduced installation height saves space
- High thermal efficiency reduces energy costs
- Fast start-up and shut-down times improve product quality
- Versatility across various industries and applications
- Lower maintenance requirements due to self-cleaning effect
