Product Description

Centrifugal scraper film evaporator is a kind of high efficient evaporation equipment utilize high speed rotary agitator make the liquid uniformly distributed as membrane when evaporation, it also process for deodorization, deaeration and heating, cooling unit operation, it is widely use in the industry of pharmacy, food, light industry, petroleum, chemical, environmental protection.


It adopts advanced foreign technology and has an international level in the field of domestic wiped film evaporators. This equipment has been used as the main engine of the "scraper type vacuum smelting unit".


Working Principle 

The material enters the evaporator radially from above the heating zone; the distributor distributes to the evaporator to heat the wall surface, and then the rotating wiper scrapes the material onto the continuous uniform heating surface to form a thick and uniform liquid film, and spirally Push forward. In this process, the rotating wiper ensures high-speed turbulence of the continuous and uniform liquid film, and prevents the liquid film from coking and fouling on the heating surface, thereby increasing the total coefficient. The light component is vaporized to form a vapor stream which rises through the vapor-liquid separator to an external condenser directly connected to the evaporator; the recombination fraction is discharged from the cone at the bottom of the evaporator. A unique distributor not only has the material evenly poured onto the inner wall of the evaporator, prevents the material from splashing into the vapor stream inside the evaporator, but also prevents the material that has just entered from flashing here, which is beneficial to the elimination of the foam. It can only evaporate along the heating surface. At the top of the scraper evaporator is equipped a centrifugal separator designed according to the material characteristics to separate the droplets in the rising steam stream and return to the distributor.



As a kind of high efficient evaporation equipment, it utilize high speed rotary agitator make the liquid uniformly distributed as membrane when evaporation, it also process for deodorization, deaeration and heating, cooling unit operation, it is widely use in the industry of pharmacy, food, light industry, petroleum, chemical, environmental protection.
