LG series centrifugal scraper blade film evaporator

Overview: The scraper thin-film evaporator is an efficient evaporation and distillation equipment. It forms a uniform liquid film by high-speed rotation for evaporation or distillation.

It can also perform unit operations such as deodorization, defoaming reaction, heating and cooling. It is widely applied in Chinese & Western pharmaceutical, food, light industry, petroleum, chemical, environmental protection and other industries.
The centrifugal scraper thin-film evaporator adopts imported technology and reaches international advanced level among domestic scraper thin-film evaporators. This equipment has been used as the main unit of the "scraper type vacuum honey refining unit" and won the Third Prize of Science and Technology Progress Award of the State Pharmaceutical Administration.
Performance & Features
This equipment adopts centrifugal sliding groove rotor, which is an advanced structure evaporator overseas. A liquid film can be formed even under very low flow rate. Deposits on the inner wall of the cylinder evaporation section can be quickly removed by movable scrapers. Compared with fixed-gap scraper evaporators, its evaporation capacity can be increased by 40-69%. It has the following performances and features:
1. High heat transfer coefficient, large evaporation capacity, evaporation intensity up to 200kg/m²·hr, high thermal efficiency.
2. Short material heating time, about 5 to 10 seconds. It operates under vacuum, which is more favorable for heat-sensitive materials. It keeps all components from decomposition and guarantees product quality.
3. Wide adaptability to viscosity variation, capable of treating both high and low viscosity materials. Material viscosity up to 100,000 centipoise (CP).
4. The material residence time inside the evaporator can be adjusted by changing the rotation direction of scraper grooves.
5. The inner wall of evaporation cylinder is precisely bored and polished, hardly causing coking and scaling.
6. Easy operation and convenient adjustment of product indicators. Continuous automatic production can be realized under sealed conditions.
7. Small floor space, simple structure, convenient maintenance and easy cleaning.
