Scraper thin film evaporators works

The material liquid preheated to a certain temperature enters the evaporator from the upper inlet of the thin film evaporator, and is divided into multiple streams into the inner wall of the cylinder by the rotating liquid distributor. Each strand of material forms a uniform liquid film on the heated inner wall. The liquid film absorbs the heat transferred from the heating medium to the evaporation surface, and rapidly evaporates the substance on the surface. Repeated evaporation, the material liquid is gradually concentrated. The secondary steam evaporated in the thin film evaporator passes through the secondary steam outlet to the external condenser for condensation. The cooling medium of the condenser is generally water at room temperature. Because evaporation is often a boiling evaporation process with bubbles and liquid splashes, before the secondary steam is condensed, it needs to pass through a mist separator to remove the entrained liquid droplets. The thin-film evaporator is a new type of high-efficiency evaporator, with high heat transfer coefficient, high evaporation intensity, strong adaptability to heat-sensitive materials, and good adaptability to viscous, fouling and crystalline materials. The concentration of the finished product of the thin film evaporator can be adjusted widely.
