Film evaporator is through rotating film scraper device forced into a film, high speed flow, high heat transmission efficiency, short duration of stay time (about 10~50s).
This type film evaporator is a new and high efficiency evaporator which could do falling film evaporation under vacuum conditions.Film evaporator consists of one or more cylinder body with jacket heating and film scraper device which is rotating in the cylinder body. Use film scraper device to let feedstock material into uniform liquid film at heating surface and move down, during this process, the low-boiling component is evaporating, and the residue is discharged through the evaporator bottom.
