1、 Overview:

1、 Overview:

Scraper type thin film evaporator is an efficient 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 deodorization, defoaming reactions, heating, cooling and other unit operations, and can be widely used in industries such as pharmaceuticals, food, light industry, petroleum, chemical, and environmental protection in China and the West.

The centrifugal scraping plate thin film evaporator adopts advanced foreign technology and has an internationally leading position in the field of scraper thin film evaporators in China. This equipment 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 Pharmaceutical Administration.

2、 Performance and Features:

This equipment adopts a centrifugal sliding groove rotor, which is currently the latest structure evaporator abroad. 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 advantages:Performance and Features：

1. 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.

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 advantageous for thermosensitive materials, keeping various components from decomposing and ensuring product quality.

3. 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 100000 centipoise (CP)

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

5. The inner wall of the evaporation section cylinder is precision bored and polished, making the surface less prone to coking and scaling.

6. Easy to operate, easy to adjust product indicators, and capable of continuous production under closed conditions with self-control.

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