Overview of centrifugal scraped film evaporator
       The scraper thin film evaporator is a type of evaporation and distillation equipment that uses high-speed rotation to distribute liquid into a uniform thin film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reactions, heating, and cooling. It is suitable for Chinese and Western pharmaceuticals, food, light industry, petroleum, chemical industry, environmental protection and other industries.

Performance and features
       This equipment adopts a centrifugal sliding groove rotor, which can form a thin film even when the flow rate is very small. The sludge in the treatment liquid attached to the inner wall surface of the cylinder evaporation section can be quickly removed by the movable scraper. Compared with the scraper evaporator with a fixed gap, the evaporation capacity can be increased.40-69%, it has the following performance and features:
       1, high heat transfer coefficient value, large evaporation capacity, evaporation intensity can reach200kg/m²·hr, high thermal efficiency.
       2, the material heating time is short, about5seconds to10seconds, and works under vacuum conditions, which is more beneficial to heat-sensitive materials and keeps various components without any decomposition.
       3, adapts to a wide range of viscosity changes, can handle both high and low viscosity materials, and the material viscosity can reach1010,000 centipoise (CP).
       4. Changing the rotation direction of the scraper groove can adjust the processing time of the material in the evaporator.
       5, The inner wall of the evaporation section cylinder has been precision bored and polished, and the surface is not prone to coking and scaling.
       6, easy to operate, easy to adjust product indicators, and can be automatically controlled for continuous production under closed conditions.
       7, The equipment occupies a small area, has a simple structure, is easy to maintain and clean.
