Abstract

Cannabis material is frozen within an inner chamber and agitated, such as by rotating the inner chamber within an outer chamber. Filters limit the passage of cannabis material from the inner to the outer chamber to primarily allow the passage of cannabis trichomes through the filters. Air flows through the outer chamber from an air inlet to an air outlet and entrains the filtered material within an air stream. The entrained material is separated and collected, such as by one or more cyclone separators.

Claim(s)

1 . An apparatus for separating trichome containing cannabis material from cannabis plant material, the apparatus comprising: a first chamber comprising an interior and an exterior and a first chamber access opening communicating from the exterior to the interior of the first chamber; a second chamber comprising an interior and an exterior and a second chamber access opening, the second chamber being supported for rotation within the first chamber, wherein cannabis plant material is loadable through the first chamber access opening and through the second chamber access opening into the interior of the second chamber; the second chamber comprising a plurality of filter receiving openings communicating between the interior and exterior of the second chamber; a filter covering each of the filter receiving openings and sized to allow the passage of trichome sized plant material from cannabis plant material within the second chamber; a cooling source inlet through which a cooling material that freezes cannabis material in the second chamber is delivered; a motor coupled to the second chamber and operable to rotate the second chamber within the first chamber; a first chamber outlet opening communicating from the interior to the exterior of the first chamber; a fan comprising a fan inlet and a fan outlet, the fan outlet being coupled to the first chamber for directing air through the first chamber and outwardly through the at least one first chamber outlet opening; and a cyclone separator comprising a separator inlet coupled to the first chamber outlet opening, the cyclone separator receiving air from the first chamber and collecting material, including trichomes, exiting from the second chamber through the filters, the cyclone separator comprising a separator outlet coupled to the fan inlet.;
17 . A method of separating cannabis material containing trichomes from cannabis material comprising: placing trichome containing cannabis material within a chamber: freezing the trichome containing cannabis material; flowing air past the chamber; agitating the frozen trichome containing cannabis material; filtering the agitated frozen trichome containing cannabis material to allow trichome sized filtered cannabis material, including trichomes, to enter the flowing air; and separating the filtered material from the flowing air.;
23 . An apparatus for separating trichomes containing cannabis material from cannabis plant material, the apparatus comprising: a first chamber comprising an interior and an exterior and a first chamber access opening communicating from the exterior to the interior of the first chamber; a second chamber comprising an interior and an exterior and a second chamber access opening, the second chamber being supported for rotation within the first chamber, wherein cannabis plant material is loadable through the first chamber access opening and through the second chamber access opening into the interior of the second chamber; the second chamber comprising a plurality of filter receiving openings communicating between the interior and exterior of the second chamber; a filter sized in the range of from 60 microns to 135 microns covering each of the filter receiving openings; a cooling source inlet for receiving cooling material through the inlet that freezes cannabis material in the second chamber; a motor coupled to the second chamber and operable to rotate the second chamber within the first chamber; a plurality of first chamber outlet openings communicating from the interior to the exterior of the first chamber; a fan comprising a fan inlet and a fan outlet, the fan outlet being coupled to the first chamber for directing air downwardly through the first chamber and outwardly through the plurality of first chamber outlet openings; and a plurality of cyclone separators each comprising a separator inlet coupled to a first chamber outlet opening that receives air from the first chamber, the cyclone separators collecting material, including trichomes, exiting from the second chamber through the filters, the cyclone separators also each comprising a separator outlet coupled to the fan inlet; an air flow manifold comprising an air flow manifold inlet coupled to the fan outlet, the air flow manifold having at least one air flow manifold outlet coupled to the first chamber through which air from the fan is directed downwardly into the first chamber. wherein the second chamber has a second chamber longitudinal axis and a length direction along the second chamber longitudinal axis, the apparatus comprising a cooling fluid delivery conduit coupled to the cooling source inlet and extending along at least a majority of the length of the second chamber, the cooling fluid delivery conduit comprising a plurality of cooling fluid outlets along the length of the cooling fluid delivery conduit through which cooling fluid is delivered to the interior of the second chamber; and a motor control that is operated to rotate the second chamber after the cannabis material within the second chamber is frozen and wherein the motor control is operated to rotate the second chamber at a rate of from 5 to 60 rpm to agitate the cannabis material in the second chamber.
