Hinge-bladed wiped film evaporator is a type of wiped film evaporator, and its structural characteristics include:
Hinge-bladed wiped film evaporator, each blade has a central rotating shaft, which drives the blade through a connecting rod mechanism. The hinged blade is tightly attached to the heating wall surface by centrifugal force and slides at a certain angle to wipe the raw material into the required liquid film and prevent scaling and coking on the heating surface. This type of design allows the blade to provide effective pressure on the liquid film, improve the high evaporation ratio of the material, also it can help to reduce the residue of the material. It is suitable for materials that are prone to scaling on the heating surface, contain solid particles, or have a tendency to crystallize during the evaporation process, and require concentration into dry materials, with a processing viscosity of 35000 mpas.
This type of rotor is widely used by changing the frequency and mass of the scraper and adjusting the centrifugal force.
The blade material is usually the same metal material as the evaporator cylinder, and PTFE material can also be used.
