Title (EN) METHOD AND APPARATUS FOR PASTEURIZING AND DEHYDRATING MARIJUANA
(FR) PROCÉDÉ ET APPAREIL DE PASTEURISATION ET DE DÉSHYDRATATION DE MARIJUANA
Abstract:
(EN) A method and apparatus for pasteurizing and drying marijuana plant materials using a microwave-vacuum chamber. The pasteurizing and drying are carried out with no use of ionizing radiation and with rapid drying. Pasteurization is done at a temperature and for a time period that are sufficient to reduce microorganisms to an acceptably low level, while not significantly reducing the psychoactive compounds in the material. In the process, the pressure inside a vacuum chamber is reduced to a first pressure less than atmospheric. The material is maintained in the vacuum chamber at the first pressure at a pasteurizing temperature while irradiating the material with microwave radiation. The pressure is then reduced to a second pressure lower than the first pressure and the material is maintained in the vacuum chamber at the second pressure for a time period at a dehydrating temperature lower than the pasteurizing temperature while irradiating the material with microwave radiation. The pasteurizing and dehydrating steps can be done in the reverse order.
(FR) L'invention concerne un procédé et un appareil pour pasteuriser et sécher des matériaux végétaux de marijuana à l'aide d'une chambre à micro-ondes sous vide. La pasteurisation et le séchage sont effectués sans recours à un rayonnement ionisant et avec un séchage rapide. La pasteurisation est effectuée à une température et pendant une période de temps qui sont suffisantes pour réduire les micro-organismes à un niveau bas acceptable, tout en ne réduisant pas significativement les composés psychoactifs dans la matière. Dans le procédé, la pression à l'intérieur d'une chambre à vide est réduite à une première pression inférieure à la pression atmosphérique. La matière est maintenue dans la chambre à vide à la première pression à une température de pasteurisation tout en irradiant la matière avec un rayonnement de micro-ondes. La pression est ensuite réduite à une deuxième pression inférieure à la première pression et la matière est maintenue dans la chambre à vide à la deuxième pression pendant une période de temps à une température de déshydratation inférieure à la température de pasteurisation tout en irradiant la matière avec un rayonnement de micro-ondes. Les étapes de pasteurisation et de déshydratation peuvent être réalisées dans l'ordre inverse.
