Continuous final concentration of viscous products without fouling, where tubular evaporators fail The Alfa Flash Evaporator is a plate‑type evaporation system specifically engineered to operate as a final concentrator ("finisher") for products with high solids content, elevated viscosity, or scaling tendency, such as whey concentrates, dairy proteins, fruit extracts, and heat‑sensitive food ingredients. The system applies the flash evaporation principle combined with extremely high turbulence, preventing boiling directly on the heat‑transfer surface. This design creates a permanent self‑cleaning effect, eliminating fouling‑related shutdowns and enabling stable, continuous operation in applications where conventional tubular evaporators clog. Main features Self‑cleaning effect by high shear The evaporator operates with liquid circulation rates 10 to 100 times higher than traditional systems, generating intense turbulence and shear stress at the plate surface. Benefit: Continuous mechanical scrubbing prevents fouling and significantly improves clean‑in‑place (CIP) efficiency. High efficiency with variable‑viscosity fluids For pseudoplastic products whose apparent viscosity decreases under shear, the high turbulence reduces viscosity during operation. Benefit: Improved heat‑transfer efficiency, lower pumping power requirements, and reduced electrical consumption. Ideal as a final concentrator (finisher) The Alfa Flash Evaporator tolerates suspended solids and early crystallization phenomena that typically cause plugging in other evaporator designs. Benefit: Reliable final‑stage concentration at high solids levels without unplanned stoppages. Preservation of product thermal integrity By avoiding direct boiling on metallic surfaces, the risk of burn‑on is eliminated. Benefit: Protection of organoleptic and functional properties in concentrates of whey, proteins, fruits, and other heat‑sensitive products. The Alfa Flash Evaporator delivers robust final concentration, superior product quality, and maximum plant availability, making it the preferred solution for demanding dairy and whey applications.
