Scraper type thin film evaporator is an efficient 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 deodorization, defoaming reactions, heating, cooling and other unit operations, and can be widely used in industries such as pharmaceuticals, food, light industry, petroleum, chemical industry, and environmental protection in China and the West.
The centrifugal scraper film evaporator adopts foreign technology and has a technological level in the field of scraper film evaporators in China. This equipment was once used as the main unit of the "scraper type vacuum honey refining unit" and won the third prize of scientific and technological progress from the Medical Administration Bureau.
This equipment adopts a centrifugal sliding groove rotor, which is a new structure evaporator in foreign countries. It can form a thin film even at low flow rates. The sediment in the treatment liquid attached to the inner wall surface of the evaporation section of the cylinder can be quickly removed by a movable scraper. Compared with a fixed gap scraper evaporator, the evaporation capacity can be increased by 40% -69%
1, the heat transfer coefficient K value is high, the evaporation capacity is large, the evaporation intensity can reach 200Kg/m2.hr, high thermal efficiency.
2, the material heating time is short, about 5 seconds to 10 seconds, and working under vacuum conditions, more favorable to heat-sensitive materials, keep various components do not produce any decomposition, to ensure product quality.
3, adapt to a wide range of viscosity changes, high and low viscosity can be processed, the material viscosity can be up to 100,000 centipores (CP).
4, change the direction of the scraper groove rotation, you can adjust the material in the evaporator play time.
5, evaporation section cylinder inner wall after precision boring and polishing treatment, the surface is not easy to produce coking, scaling.
6, easy to operate, easy to adjust product indicators, under closed conditions, can be controlled for continuous production.
7, the equipment covers a small area, simple structure, easy maintenance, easy cleaning.
