Product Description

Vacuum Scraper Concentrator is an advanced industrial evaporation system designed for continuous concentration of heat-sensitive, viscous, or fouling-prone materials (e.g., pharmaceuticals, polymers, food extracts, resins). Utilizing a rotating scraper mechanism and thin-film evaporation principle under controlled vacuum, it achieves rapid solvent removal at low temperatures (≤60°C), preserving product integrity while preventing scaling.

Key Features:

• High-Efficiency Heat Transfer: Creates turbulent flow via agitated scraping, enhancing evaporation rates by 40-60% vs. static evaporators.

• Zero-Fouling Operation: Self-cleaning scrapers eliminate residue buildup, ensuring uninterrupted 24/7 production.

• Modular Design: Customizable evaporation area (0.1-50 m²), material options (316L SS, Hastelloy), and vacuum stages.

• Energy-Saving: Low-temperature operation reduces steam consumption by 30% compared to atmospheric systems.

• Automated Control: Integrated PLC with sensors for vacuum/pressure/temperature regulation and CIP/SIP compatibility.

Applications:

• Chemical: Polymer concentration, solvent recovery (DMF, THF)

• Pharma: API crystallization, herbal extract purification

• Food: Fruit puree thickening, natural flavor concentration

• Environment: Waste liquid volume reduction
