I. Overview:

      The scraped film evaporator is a high-efficiency evaporation and distillation equipment that uses high-speed rotation to distribute the liquid evenly into a thin film to evaporate or distill. It can also perform deodorization, defoaming reactions, and heating and cooling unit operations. It can be widely used in medium and Western pharmaceutical, food, light industry, petroleum, chemical, environmental protection and other industries.

   The centrifugal scraper thin film evaporator adopts foreign advanced technology, and has a leading position in the international level in the domestic scraper thin film evaporator field. This equipment was once used as the main engine of the Scraper Vacuum Mixing Unit and won the third prize of Science and Technology Progress Award of the State Pharmaceutical Administration.

2. Performance and characteristics:

      This equipment uses a centrifugal sliding grooved rotor, which is the latest foreign evaporator. It can form a thin film even at a small flow rate. The sludge in the treatment liquid attached to the inner wall of the evaporation section of the cylinder can be quickly moved by the movable scraper. Removed, compared with the fixed gap scraper evaporator, the evaporation can be increased by 40%-69%. It has the following performance and characteristics :

1. High heat transfer coefficient value, large evaporation capacity, evaporation intensity up to 200kg/m2·hr, high thermal efficiency.

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 beneficial to heat-sensitive materials, keeping various components without any decomposition, and ensuring product quality.

3. It adapts to a wide range of viscosity changes, both high and low viscosity materials can be processed, and the annual material can be as high as 100,000 centipoise (CP)

4. Changing the rotation direction of the scraper groove can adjust the handling of materials in the evaporator.

5. The inner wall of the evaporation section cylinder is precisely bored and polished, so the surface is not easy to cause coking and scaling.

6. Convenient operation, easy adjustment of product indicators, continuous production can be controlled automatically under airtight conditions.

7. The equipment has a small footprint, simple structure, convenient maintenance and easy cleaning.
