Scraped Surface Evaporation System
Description
Technical Parameters
KMK ASME Standard Wiped film evaporator (WFE) distillation is a high-efficiency thin-film evaporation system designed for precise separation, concentration, and solvent removal, especially suitable for high-viscosity, heat-sensitive, fouling, or foaming materials.
Scraped surface evaporators (also known as wiped film evaporators) are highly efficient evaporation and concentration equipment specifically designed for high-viscosity, heat-sensitive, or fouling materials. They are widely used in various industries, including petroleum, chemical, pharmaceutical, food, and environmental protection. Their core advantage lies in the high-speed rotating scraper that forms and continuously renews an extremely thin turbulent liquid film on the heating surface, achieving a low-temperature, rapid, and uniform evaporation process.
Products Description
The scraper forces film formation, resulting in a liquid film thickness of only 0.1–2 mm. This leads to a high heat transfer coefficient and an evaporation intensity of up to 200 kg/m²·h, significantly higher than traditional evaporators.
1. Short Material Residence Time, Suitable for Heat-Sensitive Materials
The material residence time in the evaporator is only 5–50 seconds. Combined with vacuum low-temperature operation (as low as 28℃), it effectively prevents the decomposition, polymerization, or deterioration of heat-sensitive components, making it particularly suitable for concentrating products such as fruit juices, traditional Chinese medicine extracts, and vitamins.
2. Adaptable to High-Viscosity and Complex Materials
It can handle materials with viscosities up to 100,000 centipoise, such as resins, honey, tannins, and polymer solutions. It is less prone to coking and scaling, ensuring stable operation.
3. Flexible Operation and Convenient Maintenance
It can operate continuously, with adjustable scraper angle and rotation speed to meet different process requirements. The compact structure and top quick-opening design facilitate cleaning and maintenance, making it suitable for pharmaceutical and food production in GMP environments.
4. Energy Saving, Environmentally Friendly, and Intelligent Upgrades
The new electromagnetic heating scraped surface evaporator has a thermal efficiency exceeding 90%, saving more than 30% energy compared to traditional steam heating. Precise temperature control (±1℃) and no risk of steam pipe leakage make it suitable for green factories and intelligent manufacturing scenarios.
What are the wide-ranging applications of Industrial Evaporation Systems?
- Chemical Industry: High-salt wastewater concentration, organic solvent recovery (such as DMF, ethanol), polymer devolatilization;
- Pharmaceutical Industry: Concentration of traditional Chinese medicine extracts, antibiotic solution recovery, purification of fat-soluble vitamins;
- Food Industry: Low-temperature concentration of fruit juice, honey degassing, chocolate slurry processing;
- Environmental Protection: Lithium battery waste liquid treatment, reduction of salt-containing hazardous waste, pretreatment of high-COD wastewater;
- Emerging Applications: Lithium battery electrolyte recovery, purification of high-value natural products, etc.
With its high efficiency, low temperature operation, and strong adaptability, the scraped surface evaporator has become the preferred equipment for processing difficult-to-evaporate materials, and is one of the key pieces of equipment for achieving high-quality, high-efficiency, and green production.
