Centrifugal Thin Film Evaporator (Rotary Scraper Type)
The rotary scraper type thin film evaporator is a high-efficiency evaporation and distillation system that produce a thin film using centrifugal force under high-speed rotation. It can also undertake operations like defoaming reactions, deodorization, heating and cooling, widely applicable to industries including pharmaceuticals, food, chemical, petroleum, and more.
The scraper is driven by rotor through scraper guide grooves to achieve circular motion under the effect of centrifugal force. With this advanced structure, this thin film evaporator can form thin film even in the case of low flow rate, which enables the evaporation rate to be increased by 40%-69%.
