  • Patent number: 9950976
    Abstract: A cannabidiol extraction and conversion process includes an extraction process including a sizing unit wherein raw Cannabis plant material is reduced to a uniform size, a blending unit wherein an extraction solvent is blended together with the Cannabis plant material to form an initial extract, and a primary solvent exchange rotary evaporator unit wherein an exchange solvent is added to the initial extract, and a processed extract rich in cannabidiol is obtained. A conversion process includes a conversion rotary reflux unit wherein the processed extract is combined and processed with an acidic component, a separator unit wherein a solvent is added and a separator organic effluent is obtained, a secondary solvent exchange rotary evaporator unit wherein a further solvent is added, and a fractionation unit wherein the tetrahydrocannabinol obtained is separated into a plurality of functional fractions for selective blending.
