System, Method and Apparatus for Cannabinoid Tincture Separation and Solvent Recovery

摘要

A system for processing cannabinoids and recovering solvent has a vessel for a mixture of cannabinoids and solvent. A pump forms a vacuum in the system to draw the mixture into a first heat exchanger to pre-heat the mixture. A falling film evaporator receives the mixture from the first heat exchanger, and boils the mixture to form a solvent vapor. The falling film evaporator collects the cannabinoids from the mixture as a crude oil. The first heat exchanger receives the solvent vapor. Heat is transferred to incoming mixture of the system, and cools and condenses the solvent vapor to form solvent condensate and vapor. A second heat exchanger receives and further cools the solvent condensate and vapor to form further condensed solvent and some solvent vapor. The pump receives the further condensed solvent and some solvent vapor and increases pressure to form solvent liquid and recovers solvent liquid for reuse.
