Alfa Flash Evaporator

• •Self-Cleaning Effect by High Shear: The system operates with liquid circulation rates 10 to 100 times greater than other systems, generating extreme turbulence and high shear stress at plate walls. This creates a continuous scrubbing effect that prevents fouling and improves CIP cleaning efficiency.
• •Efficiency with Variable-Viscosity Fluids (Shear-Thinning): For pseudoplastic products whose viscosity decreases under agitation, the high shear design reduces apparent viscosity during processing. This increases heat-transfer efficiency and allows the use of smaller, lower-power pumps, reducing initial investment and electrical consumption.
• •Ideal as Final Concentrator (Finisher): Its ability to handle suspended solids and incipient crystallization makes it the ideal solution for the final evaporation stage, where solids levels are critical and other evaporators fail due to clogging.
• •Product Thermal Integrity: By avoiding direct boiling on the metallic surface, the risk of product burn-on is eliminated. This is vital for maintaining organoleptic quality in fruit concentrates, proteins, or heat-sensitive extracts.

How it works

The AlfaFlash is a plate evaporator that operates as a forced-circulation flash evaporator. This forced circulation means a pump recirculates the liquid between the cyclonic separator vessel and the plate evaporator itself, creating a highly turbulent flow inside the equipment. In this process, boiling does not occur in the plate heat exchanger; instead, the liquid to be concentrated is simply heated under pressure. Actual evaporation takes place when the heated liquid is discharged into the separator vessel, where pressure is released and **the liquid vaporizes instantaneously** (flash evaporation). Vacuum is applied to the system to lower the boiling temperature, created by condensing the vapor from the last effect in a highly efficient and compact condenser. In combination with multiple effects, steam consumption is reduced: vapor produced in one effect is used as the heating medium for the next. Combined with thermal vapor recompression (TVR) and/or mechanical vapor recompression (MVR), steam consumption can be reduced to a fraction of the evaporation capacity. A complete installation includes plate evaporators, preheaters, separator vessels, TVR or MVR, recirculation pumps, instruments, valves, ducts, piping, and a control panel.
