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 unit operations such as deodorization, defoaming reactions, heating, cooling, etc. It can be widely used in industries such as Chinese and Western pharmaceuticals, food, light industry, petroleum, chemical, and environmental protection.
The centrifugal scraper thin film evaporator adopts advanced foreign technology and has a leading position in the field of scraper thin film evaporators at the international level in China. This device was once used as the main unit of the scraper type vacuum mixing unit and won the third prize for scientific and technological progress from the National Medical Administration.
Performance and Characteristics
This equipment adopts a centrifugal sliding groove rotor, which is currently the latest structure evaporator abroad. 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 cylinder evaporation section 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:
Characteristic 1
The heat transfer coefficient is high, the evaporation capacity is large, the evaporation intensity can reach 200kg/m2 · hr, and the thermal efficiency is high.
Characteristic 2
The heating time of the material is short, about 5 to 10 seconds, and working under vacuum conditions is more beneficial for thermosensitive materials, maintaining that various components do not decompose and ensuring product quality.
Characteristic 3
Adapted to a wide range of viscosity changes, it can handle both high and low viscosity substances, and the material viscosity can reach up to 100000 CP.
Characteristic 4
Changing the rotation direction of the scraper groove can adjust the material's processing time in the evaporator.
Characteristic 5
The inner wall of the evaporation section cylinder has undergone precision boring and polishing treatment, making the surface less prone to coking and scaling.
Characteristic 6
Easy to operate, product indicators can be easily adjusted, and continuous production can be controlled under closed conditions.
Characteristic 7
The equipment has a small footprint, simple structure, convenient maintenance, and easy cleaning.

Frequently Asked Questions
What is a scraper type thin film evaporator?
It is a highly efficient evaporation and distillation device that utilizes high-speed rotation to distribute processing liquid into a uniform, thin film. This design enables fast evaporation or distillation, and can also perform unit operations like heating, cooling, deodorization, and defoaming.
What industries is this equipment suitable for?
This evaporator is widely used across multiple sectors, including Chinese and Western pharmaceuticals, food processing, light industry, petroleum, chemical engineering, and environmental protection.
Why is it highly effective for thermosensitive materials?
The heating time for materials is extremely short, taking only about 5 to 10 seconds. When combined with vacuum operation, it prevents thermal decomposition of components and ensures the high quality of the final product.
How does the centrifugal sliding groove rotor improve performance?
It allows the formation of a uniform thin film even under low flow rates. The movable scraper quickly removes sediment from the inner cylinder wall, boosting the evaporation capacity by 40-69% compared to fixed gap scraper evaporators.
What range of viscosity can this evaporator handle?
It is highly adaptable to viscosity changes and can process both high and low viscosity substances, accommodating material viscosities up to 100,000 CP.
Is the equipment prone to coking or scaling?
No. The inner wall of the evaporation section cylinder undergoes precision boring and polishing treatments, making the surface highly resistant to coking and scaling.
