Experimental thin film evaporator manufacturer

Vacuum Scraper Film Concentration Equipment

Scope of Application:

Scraper typeThin film evaporatorIt is an efficient evaporation and distillation equipment that uses high-speed rotation to forcibly distribute liquid into a uniform 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 industry, environmental protection in China and the West.

Main Features:

This equipment adopts a centrifugal sliding groove rotor, which is a new structure evaporator in foreign countries. 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 the movable scraper. Compared with the fixed gap scraper evaporator, the evaporation capacity can be increased by 40% -69%. It has the following performance and characteristics:

The heat transfer coefficient value is high, the evaporation capacity is large, the evaporation intensity can reach 200kg/m2hr, and the thermal efficiency is high.

The heating time of the material is short, between about 5 seconds and 10 seconds, and working under vacuum conditions is more advantageous for thermosensitive materials, keeping various components from decomposing and ensuring product quality.

L can adapt to a wide range of viscosity changes, and can handle both high and low viscosity materials. The material viscosity can reach up to 100000 centipoise (CP).

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

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

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

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

Application Area:

In heat exchange engineering, scraper typeThin film evaporatorWidely applied. Especially for the heat exchange of thermosensitive materials (with short time), the scraper film evaporator is conducive to the heat exchange process, and through different scraper designs, complex product distillation can be carried out.

Scraper evaporators have been used in the following fields for the purpose of evaporation concentration, desolvation, stripping, reaction, degassing, deodorization, etc., and have achieved good results;
