Patent ID: 10787429

Abstract:
A method for manufacturing high-purity tetrahydrocannabinolic acid. The method includes providing Cannabis sativa l. biomass, mechanically separating trichomes into phytochemical mixture including tetrahydrocannabinolic acid, drying the phytochemical mixture, creating a first press product by pressing the dried phytochemical mixture through a mesh screen with a pressure within the range of 5-120 psi and at a first temperature between 90-120° F. The first press product is aged to naturally release acid form cannabinoids from terpenes, undesirable lipids, and chlorophyll. Second pressing the aged first press product at gradually increasing temperatures to release the undesirable lipids and chlorophyll to create a second press product. In a third press increasing the temperature to beyond the melting point, and below the boiling point of tetrahydrocannabinolic acid to yield high-purity tetrahydrocannabinolic acid having a 90-99.99% purity.
