Scraper type thin film evaporator is a high-efficiency evaporation and distillation equipment that uses high-speed rotation to distribute liquid into a uniform thin film for evaporation or distillation. It can also be used for deodorization, defoaming reactions, heating, cooling and other unit operations, and is widely applicable in industries such as pharmaceuticals, food, light industry, petroleum, chemical industry, and environmental protection.
This equipment adopts a centrifugal sliding groove rotor, which 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% to 69%.

Has the following performance and characteristics:
① The heat transfer coefficient value is high, the evaporation capacity is large, the evaporation intensity can reach 100kg/m² · hr, and the heat transfer efficiency is high.
② The heating time of the material is short, between about 5 seconds and 10 seconds, and it works under vacuum conditions, which is more advantageous for thermosensitive materials, keeping various components from decomposing and ensuring product quality.
③ It can adapt to a wide range of viscosity changes and handle both high and low viscosity materials, with material viscosity up to 100000 centipoise (CP).
④ Changing the rotation direction of the scraper groove can adjust the maintenance time of the material in the evaporator.
⑤ The inner wall of the evaporation section cylinder is precision bored and polished, making the surface less prone to coking and scaling.
⑥ Easy to operate, easy to adjust product indicators, and capable of continuous production under closed conditions with self-control.
⑦ The equipment has a small footprint, simple structure, easy maintenance, and easy cleaning.
