Abstract: A method of separating trichomes from cannabis plant flowers that begins with delivering the cannabis plant material to a hopper and continuously moving the cannabis material from the hopper to a porous container in a bath of cold water, at a controllable rate, and moving the cannabis material contained in the porous container, through the cold bath from an entrance end, to an exit end, thereby removing trichomes, which exit the porous container into the cold water. The remaining cannabis plant material is moved out of the exit end of the bath, at substantially the same rate as the cannabis plant material enters the bath. Finally, the water from the bath is substantially continuously filtered thereby separating the trichomes from the cold water.

Abstract: A method of delivering a set of nonuniform cannabis inflorescences (“buds”) that fit within a target weight range. The method includes iteratively weighing a bud and automatically placing the weighed bud into one holding bin, out of a set of holding bins and automatically determining if the weight of any combination of the contents of the set of holding bins fits within the target weight range. When a combination of the contents of the holding bins fits within the target weight range, combining these holding bin contents together.
