Answer: The Liquid Extraction & Vacuum Evaporator is specifically engineered as a bridge between laboratory testing and industrial-scale manufacturing. By utilizing a pilot-scale footprint, PCM allows engineers to accurately calculate thermal transfer coefficients, solvent recovery rates, and residence times under real-world vacuum conditions. This data is critical for scaling up processes without risking batch failure. The system’s geometry and heating efficiency mimic our large-capacity units, ensuring that the chemical profiles developed in the pilot phase remain consistent when moved to a full production line.

Answer: Our Double-effect Vacuum Evaporator utilizes a sophisticated thermal recycling process to significantly reduce operational costs. In this system, the secondary steam generated from the first effect is used as the heating source for the second effect. Because the second vessel operates at a higher vacuum (and thus a lower boiling point), the waste heat from the first stage is sufficient to drive evaporation in the second. This method can reduce steam consumption by nearly 40% to 50% compared to single-effect units, making it the most sustainable choice for high-volume liquid processing.

Answer: The Liquid Vacuum Evaporator creates a low-pressure environment that effectively lowers the boiling point of the liquid medium. By operating at high vacuum levels, we can achieve rapid evaporation at temperatures as low as 45°C to 50°C. This is essential for botanical extractions and pharmaceutical ingredients where high heat would cause thermal degradation, oxidation, or the loss of volatile aromatic compounds. Maintaining these low temperatures ensures the final concentrate retains its “fresh” biological activity and natural color, which are key quality indicators for premium market products.

Answer: We construct our pilot-scale units using 316L stainless steel to provide maximum chemical resistance against a broad spectrum of organic solvents and corrosive botanical acids. Unlike standard 304SS, the addition of molybdenum in 316L provides superior protection against pitting and stress-corrosion cracking. This is particularly important in a multi-function unit that may handle different chemical profiles in a single week. The mirror-polished interior surfaces (Ra < 0.4μm) also prevent material adhesion, ensuring that cross-contamination is eliminated between different research batches.

Answer: The Liquid Vacuum Evaporator system is equipped with a high-efficiency vertical shell-and-tube condenser designed for rapid heat exchange. As the vaporized solvent enters the cooling zone, it is instantly condensed into a liquid state and directed into a specialized recovery tank. This closed-loop design typically achieves a solvent recovery rate of over 95%. For laboratories and pilot plants, this high efficiency significantly lowers the cost of raw materials and prevents the release of volatile organic compounds (VOCs) into the workspace, ensuring a safer and more environmentally compliant production environment.
