Plant product extraction apparatus
A plant product extraction apparatus or extractor is provided for separating or grading fine particles from a larger portion of material, such as separating trichomes from a stalk or flower of a plant. The apparatus imparts a plurality modes or patterns of oscillations and vibrations to a particle separator or sieve that holds the plant matter. A motor drives a back and forth motion to a support platform supporting a sieve. The sieve is constrained by a retention tray that is supported by the support platform. One or more vibratory motors provide rapid shaking vibration through the retention tray to the sieve. A haptic transducer or mechanical agitators may be provided to increase throughput of the apparatus. The various motors and locomotion patterns facilitate the separation of finer plant materials from a larger portion of a plant.
