Fundamental

       The rotary film evaporator is a new type of high-efficiency evaporator that continuously and evenly forms a film on the heating surface by rotating the scraping film device in the cylinder to carry out falling film evaporation under high vacuum conditions. The use of a rotating thin film evaporator for evaporation, concentration, degassing, desolvation, and distillation of a material containing a heat sensitive substance can effectively prevent the heat sensitive substance from being decomposed by heat for a long time, thereby affecting product quality and improving evaporation efficiency.

       The material first enters the rotating distribution tray, and the distribution tray is continuously and evenly distributed to the vertical heating surface of the cylinder. While the material is lowered by gravity, the rotating wiper device forcibly forms a very thin turbulent liquid film on the heating surface. The light component vapor evaporated by heat is condensed from the upper outlet into the external condenser, while the unreacted fraction is discharged from the bottom of the rotating membrane evaporator.

Performance characteristics

◆Open wiper system with small pressure drop

◆High heat transfer coefficient and high evaporation efficiency

◆ Short heating time and low evaporation temperature

◆Adaptability and flexibility

Structural features

◆High-precision transmission and mechanical seal design ensure long-term smooth operation of equipment

◆Evaporation cylinder is integrally formed without intermediate flange connection

◆The surface of the cylinder has high surface finish and is not easy to stick: the finish surface finish can reach Ra0.8μm, and the special polishing finish can reach Ra0.2μm.

◆Unique defoamer structure can effectively prevent steam entrainment

◆Bottom scraper structure, which helps the discharge of high viscosity reconstituted parts

Scope of application and typical applications:

       High-efficiency thin film evaporators are now widely used in medicine, pesticides, oleochemicals, petrochemicals, fine chemicals, household chemicals, bio-chemicals, etc., mainly for the evaporation, concentration, desolvation, stripping, heat-sensitive and oxidizable materials. Reaction, degassing, deodorization (gas) taste, and the like.

       It can replace the conventional falling film evaporator for the distillation, purification, concentration and decolorization of petrochemical and chemical products;
