ABSTRACT:
A device for cleaning or refining herbage or herbal substances which operates to separate out twigs, seeds or other roughage by an agitating and straining process. The device includes a cylindrical main body internally divided into a pair of chambers by a fixed strainer or wire screen with a pair of removable end caps enclosing the chambers at each end of the cylinder. A plurality of metallic balls, preferably four, are loosely confined within one of the chambers within which the herbage to be refined is introduced. Vigorous shaking of the device will cause refined herbage to pass from the chamber containing the balls, through the strainer or screen and into the other chamber where the refined herbage may be collected in one of the end caps.
