EXTRACTING SUBSTANCES FROM BOTANICAL MATTER

A useful substance is extracted from botanical feedstock by mechanically compressing the feedstock and pumping a solvent through the compressed feedstock at high pressure while applying compressive mechanical force against the feedstock. Movement of pressurized solvent through the compressed feedsto...

More Information
Summary:A useful substance is extracted from botanical feedstock by mechanically compressing the feedstock and pumping a solvent through the compressed feedstock at high pressure while applying compressive mechanical force against the feedstock. Movement of pressurized solvent through the compressed feedstock may increase the volume of solvent in contact with the feedstock. Flow of solvent under pressure may also present a shearing force that facilitates dissociation of the useful substance from the feedstock. L'invention concerne une substance utile qui est extraite d'une matière première botanique par compression mécanique de la matière première et pompage d'un solvant à travers la matière première comprimée à haute pression, tout en appliquant une force mécanique de compression contre la matière première. Un mouvement du solvant mis sous pression à travers la matière première comprimée peut augmenter le volume du solvant en contact avec la matière première. Un écoulement du solvant sous pression peut également présenter une force de cisaillement qui facilite la dissociation de la substance utile et de la matière première.
