How The Squeegee Evaporator Works

The working principle of the scraper evaporator:

The material continuously enters the horizontal evaporator from the large diameter end, and the scratched diaphragm accelerates the distribution, immediately forming a flowing film on the heated surface. The tapered thin film evaporator relies on the centrifugal force exerted by the rotor on the material. The centrifugal force has two effective forces, one perpendicular to the heated surface and the other toward the large diameter end body (note: the same result also appears in the vertical cone thin film evaporator).

It relies on these forces to create material acceleration, and the incoming material ensures that the heated surface is sufficiently moist and does not rely on steam. Hair ratio or feed rate. Therefore, local material overheating and thermal degradation are completely reduced or eliminated. During this process, the downstream light components (low boiling point materials) and the liquid film in the same direction enter the vapor-liquid separator through the horizontal membrane evaporator.

The droplets and foam generated by the separation of steam and liquid are decomposed into a liquid phase (high-boiling substance), the separated steam enters the external condenser or the next process; the recombined component (high-boiling substance) rises along the heating wall to the small end Export.
