Scraper type thin film evaporator is a type of evaporation and distillation equipment that uses high-speed rotation to evenly distribute liquid into a thin film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reactions, heating, and cooling, and is widely applicable in industries such as pharmaceuticals, food, light industry, petroleum, chemical, and environmental protection in China and the West.

This equipment adopts a centrifugal sliding groove rotor, which is a new type of evaporator structure in foreign countries. It can form a thin film even at very 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%. It has the following performance and characteristics:
The heat transfer coefficient value is high, the evaporation capacity is large, the evaporation intensity can reach 200kg/m2 · hr, and the thermal efficiency is high.
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.
Adapting to a wide range of viscosity changes, it can handle both high and low viscosity materials, with an annual material yield of up to tens of thousands of centipedes (CP).
Changing the rotation direction of the scraper groove can adjust the maintenance practice of materials in the evaporator.
The inner wall of the evaporation section cylinder is precision bored and polished, making the surface less prone to coking and scaling.
Easy to operate, easy to adjust product indicators, and capable of continuous production under closed conditions with self-control.
The equipment has a small footprint, simple structure, easy maintenance, and easy cleaning.
