Answer: The Vacuum Scraper Concentrator is specifically engineered to process thick, sticky, or high-viscosity liquids that would otherwise stick to heating surfaces. The unit features an internal agitator equipped with PTFE (Teflon) scrapers that constantly wipe the interior wall of the heating jacket. This continuous mechanical action prevents the formation of a “material film” or crust, ensuring that heat transfer remains efficient throughout the entire cycle. By keeping the product in constant motion, the scraper ensures a successful and uniform concentration of syrups, pastes, and herbal extracts without any localized burning.

Answer: By utilizing a high-performance vacuum system, this SS304/316L Low-Temperature Vacuum Scraper Concentrator significantly reduces the internal pressure, allowing the liquid to boil at temperatures as low as 45°C to 55°C. This low-heat environment is perfect for protecting delicate active ingredients, vitamins, and natural pigments that would be destroyed by standard atmospheric boiling. This elite thermal management prevents caramelization and oxidation, ensuring that the final concentrate retains its biological activity and original aromatic profile, which is an absolute requirement for premium pharmaceutical and food products.

Answer: We offer this Scraper Concentrator in both SS304 and SS316L to match the chemical nature of your specific material. While SS304 is excellent for general food-grade applications, SS316L is recommended for pharmaceutical products or highly acidic botanical extracts due to its molybdenum content, which provides superior resistance to pitting and chemical corrosion. Using these high-grade materials ensures that your equipment remains sturdy and non-reactive, preventing metal leaching and ensuring your facility meets the most rigorous GMP and global sanitary standards.

Answer: The integrated scraper system significantly increases the evaporation rate by maintaining a high “heat transfer coefficient.” Because the scrapers prevent the product from insulating the heating wall, the thermal energy from the steam or oil jacket is transferred directly into the liquid with minimal waste. This advanced design allows the Vacuum Scraper Concentrator to achieve a much faster concentration cycle than traditional stagnant evaporators. This efficiency is ideal for industrial plants looking to increase their hourly output while maintaining extraordinary consistency in product density.

Answer: Absolutely. Despite handling high-viscosity liquids, the Scraper Concentrator is designed for easy maintenance. The interior surfaces are mirror-polished to Ra < 0.4μm, and the scraper blades are easily removable for inspection. The unit is equipped with CIP (Clean-In-Place) spray balls that allow for a thorough and effortless cleaning cycle without disassembling the entire tank. This expert sanitary design minimizes downtime between batches and ensures a professional, contamination-free environment for your next production run.
