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:
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.
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.
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 100,000 CP.
Changing the rotation direction of the scraper groove can adjust the material's processing time in the evaporator.
The inner wall of the evaporation section cylinder has undergone precision boring and polishing treatment, making the surface less prone to coking and scaling.
Easy to operate, product indicators can be easily adjusted, and continuous production can be controlled under closed conditions.
The equipment has a small footprint, simple structure, convenient maintenance, and easy cleaning.

Frequently Asked Questions
Q:What is a scraper type thin film evaporator and how does it work?
A: It is a highly efficient evaporation and distillation device that uses a high-speed rotating rotor to spread liquid into a uniform thin film on the inner wall. This thin film allows for rapid evaporation or distillation, and the system can also perform cooling, heating, deodorization, and defoaming.
Q:What are the key advantages of a centrifugal sliding groove rotor?
A: This advanced structure allows the machine to form a thin film even at very low flow rates. The movable scraper quickly clears any sediment attached to the inner wall, which increases the overall evaporation capacity by 40-69% compared to fixed gap scraper evaporators.
Q:Is this equipment suitable for heat-sensitive materials?
A: Yes. The material heating time is extremely short (about 5 to 10 seconds), and the system operates under vacuum conditions. This ensures that heat-sensitive components do not decompose, thereby maintaining high product quality.
Q:What is the maximum material viscosity this evaporator can handle?
A: The evaporator is highly adaptable to viscosity changes and can process both low and high-viscosity substances, handling material viscosities up to 100,000 CP.
Q:How is scaling and coking prevented during operation?
A: The inner wall of the cylinder evaporation section undergoes precision boring and polishing treatments. This smooth surface, combined with the continuous action of the scraper, makes it highly resistant to coking and scaling.
Q:Which industries commonly use this evaporator?
A: It is widely used in Chinese and Western pharmaceuticals, food processing, light industry, petroleum, chemical processing, and environmental protection industries.
