Answer: The Spherical Vacuum Concentrator utilizes a rounded vessel design to optimize heat distribution and structural integrity under high vacuum. Unlike flat-bottomed tanks, the spherical shape allows the liquid to form a larger surface area relative to its volume, which significantly accelerates the evaporation rate. Furthermore, the curved walls facilitate a natural convective flow during heating, ensuring that the material is processed uniformly without “cold spots.” This excellent geometry is perfect for maintaining a stable concentration environment while maximizing your hourly output of medicinal or food-grade extracts.
Answer: Our integrated Alcohol Recovery Unit is engineered to capture volatile solvent vapors with extreme precision. As the alcohol evaporates from the mixture under vacuum, it is drawn through a high-efficiency shell-and-tube condenser. This cooling system rapidly liquifies the vapor, achieving a recovery rate of over 95%. This high level of efficiency is extraordinary for reducing the cost of raw materials and preventing the release of flammable vapors into the workspace. It ensures a successful closed-loop operation that is both environmentally compliant and highly cost-effective for industrial manufacturers.
Answer: By utilizing a high-performance vacuum pump, the Spherical Vacuum Concentrator lowers the internal pressure, which effectively reduces the boiling point of the solvent. This allows for concentration to occur at temperatures as low as 45°C to 55°C, which is ideal for protecting delicate botanical enzymes, pigments, and active pharmaceutical ingredients. This elite thermal management prevents the oxidation and thermal degradation that occur at standard boiling temperatures, ensuring your final concentrate retains its absolute potency and natural aromatic profile.
Answer: We manufacture all contact parts from high-grade 304SS or 316L stainless steel to provide a non-reactive environment for solvents and acidic plant extracts. Alcohol-based extraction involves consistent exposure to volatile organic compounds, which can cause corrosion in lower-grade metals. Our sturdy stainless steel construction, combined with a mirror-polished interior (Ra < 0.4μm), ensures that the equipment remains reliable and easy to clean. This expert sanitary design prevents metal leaching and ensures your facility meets the most rigorous GMP and food safety standards.
Answer: Absolutely. While the spherical design is primarily focused on efficient evaporation and solvent recovery, it can be equipped with an internal agitator to handle thickening materials. The vacuum pressure helps pull the viscous liquid through the discharge valve, making the final collection process effortless. Our pioneering engineering ensures that even as the density of the product increases during the concentration phase, the heat transfer remains consistent, allowing you to master the production of high-quality, high-viscosity herbal pastes and chemical concentrates.
