AlfaFlash evaporation systems are designed for optimal fouling resistance. With numerous plants around the world, AlfaFlash is the well-proven reliable solution for concentrating stillage, corn steep liquor, salty effluents, fish and meat stick water and spent wash. The considerably higher shear rate (already at quite moderate flows) leads to substantially higher heat transfer efficiency, significantly lower pump costs and a more compact installation.
Space Savings
The AlfaFlash system is compact, featuring low height and low weight. The compact dimensions of the AlfaFlash plate evaporator allow for neat installation and low installation costs. A wide range of AlfaFlash evaporators is available to suit different liquids and capacity requirements.
High Heat Transfer Efficiency
Our reliable AlfaFlash evaporators provide very high thermal efficiency. The significantly higher shear rate in AlfaFlash evaporators—even with moderate flow—leads to very high heat transfer efficiency, especially for shear-thinning liquids.
High Viscosity Liquids
AlfaFlash is advantageous for evaporating high-viscosity liquids. The AlfaFlash evaporator is designed with high wall shear to minimize viscosity in the case of shear-thinning liquids (where viscosity decreases as the shear rate increases). In multi-effect evaporation systems, AlfaFlash is often used for the final concentration step. Using AlfaFlash in one or more effects of an evaporation system makes it possible to achieve very high final concentrations, even for high-viscosity liquids.
Optimized Uptime Between Cleanings
The AlfaFlash system is designed to handle fouling-prone liquids. The AlfaFlash plate evaporator in forced circulation mode generates high turbulence and high shear rates on the plate surface—providing an effective self-cleaning effect. This reduces fouling and increases system uptime. The heat transfer surfaces in the AlfaFlash plate evaporator are easily accessible for inspection or mechanical cleaning. It is more economical because the AlfaFlash system requires less CIP (Cleaning-in-Place) chemicals and discharges less water due to the low system volume.
