What are the characteristics of centrifugal scraper film evaporator
source：www.sjbyj.com Release time：2026-10-26
The centrifugal scraper film evaporator relies on the centrifugal force of the rotor to make the scraper tightly adhere to the heating cylinder wall, scraping the material into a flowing thin liquid film, and rapidly evaporating in a vacuum environment. Compared with the fixed gap scraper evaporator and the falling film evaporator, the characteristics are as follows:
1. High heat transfer efficiency and high evaporation intensity
The liquid film is thin and continuously renewed, with sufficient heat transfer and significantly better thermal efficiency than traditional evaporators. Even if the feed flow rate is relatively small, a continuous liquid film can be stably formed, and the evaporation capacity is stronger under the same heat transfer area.
2. The material has a short heating time and is suitable for thermosensitive materials
The residence time of the material on the heating wall is generally only a few seconds. Combined with vacuum low-temperature evaporation, it is not easy to cause overheating decomposition, discoloration, or deterioration. It is suitable for materials such as medicine, natural extracts, and spices that are sensitive to high temperatures.
3. Wide range of viscosity adaptability, capable of handling viscous materials
Both high and low viscosity materials can be processed, capable of handling high viscosity, slightly solid particles, and easily gelatinous liquids; The scraper continuously scrapes the inner wall, making it less likely to adhere and accumulate, greatly reducing the risk of coking and scaling. The inner wall of the cylinder is precision polished to further reduce material adhesion.
4. Adjustable dwell time and high process flexibility
The scraper has a groove structure. By adjusting the rotor speed and groove direction, the downward flow speed of the material can be changed, and the residence time can be flexibly controlled to meet the different process requirements of concentration, desolvation, and distillation; Supports continuous production and can also operate intermittently.
5. Closed vacuum operation, controllable material quality
The whole machine is sealed and equipped with a vacuum system. Low boiling point solvents can evaporate at lower temperatures; Built in foam capture structure reduces the carryover of the feed liquid by secondary steam, ensuring stable product purity and facilitating solvent recovery.
6. Compact structure, small footprint, easy cleaning and maintenance
Vertical layout, occupying less space in the factory building; Easy disassembly and assembly, with mostly stainless steel parts in contact, capable of online cleaning, low difficulty in replacing scrapers, and minimal daily maintenance workload.
