Abstract: A system (10) and method (30) for cryogenic separation of plant material are provided. A vessel (15) is filled with cryogenic fluid having a temperature at or less than -150 degrees Celsius. Plant material is placed into the vessel (15) via a basket (17) and agitation is provided to the plant material in the vessel (15) for a predetermined time period. Upon completion of the time period, the basket (17) having at least a portion of the plant material is removed from the vessel (15). Plant particulates separated from the plant material during the agitation settle to the bottom of the vessel (15). The vessel (15) is drained of the cryogenic fluid, including plant particulates separated from the plant material.
