(FR) PROCESSUS ET APPAREIL D'EXTRACTION
Abstract
(EN) Disclosed are methods of extracting products from cannabis. One method includes placing the cannabis in a container and extracting two or more different products using different solvents in at least two separate steps. The method may use steam as one of the solvents and may also involve the subsequent drying of the extracted cannabis. The method can be used with freshly harvested or dried cannabis. The feedstock cannabis is maintained in the container throughout the multiple extraction steps. Apparatus is also disclosed for use in performing the methods described.
(FR) L'invention concerne des procédés d'extraction de produits à partir de cannabis. Un procédé comprend le placement du cannabis dans un récipient et l'extraction de deux produits différents ou plus à l'aide de différents solvants dans au moins deux étapes séparées. Le procédé peut utiliser de la vapeur comme un des solvants et peut également impliquer le séchage ultérieur du cannabis extrait. Le procédé peut être utilisé avec du cannabis fraîchement récolté ou séché. La charge de départ de cannabis est maintenue dans le récipient pendant toute la pluralité d'étapes d'extraction. L'invention concerne également un appareil destiné à être utilisé dans la mise en œuvre des procédés décrits.
