Overview

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

The centrifugal scraper film evaporator adopts foreign technology and has an international status in the domestic scraper film evaporator field. This equipment was once used as the main engine of the "scraper vacuum mixing unit" and won the third prize of scientific and technological progress from the Medical Administration.

Performance and features

This equipment uses a centrifugal sliding grooved rotor. It is an evaporator with a foreign structure. 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 Compared with the scraper evaporator with fixed gap, the evaporation can be increased by 40-69%. It has the following performance and characteristics:

1. High heat transfer coefficient, large evaporation capacity, evaporation intensity can reach 200kg/m2·hr, and high thermal efficiency.

2. The material heating time is short, about 5 seconds to 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 material viscosity can be as high as 100,000 centipoise (CP)

4. Changing the rotation direction of the scraper groove can adjust the time of the material in the evaporator.

5. The inner wall of the evaporation section cylinder is precisely bored and polished, and 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.
