Yiwu Weihao Machinery Equipment Company designs and produces CBD-specific ethanol recovery falling film evaporators, the core equipment for hemp and cannabis processing industry. This equipment is specially developed to solve the pain points of traditional ethanol recovery, realizing gentle, efficient and safe solvent recycling while protecting heat-sensitive CBD, terpenes and other cannabinoids.
Pre-filter and preheat the ethanol-CBD extract mixture to 35–45°C for smooth feeding.
The mixture forms a uniform thin film on the inner wall of vertical heated tubes by gravity and precision distribution technology.
Operate under vacuum (–0.08 to –0.095 MPa) to lower ethanol boiling point to 40–60°C, with 2–5 seconds short residence time to avoid CBD degradation.
Ethanol vapor is condensed into pure liquid for direct reuse, with 90–95% single-pass recovery rate.
Concentrated CBD oil is discharged continuously, with adjustable concentration to meet subsequent processing needs.
Gentle Processing: Low-temperature vacuum operation protects CBD activity and purity.
High Recovery Efficiency: 90–95% single-pass ethanol recovery, 99%+ with multi-stage option.
Industrial Scalability: 100–1500 L/h customizable capacity, modular design for expansion.
Compliant & Sanitary: 316L stainless steel, meets GMP, FDA, CE standards.
Safe & Energy-Saving: Explosion-proof design, compatible with MVR technology for 30–40% energy saving.
Automatic Control: PLC + touch screen, real-time monitoring and unmanned operation.
