Abstract: A plant stem separating apparatus for separating a stem from plant portions extending from the stem is provided. The plant stem separating apparatus includes a cutter, and first and second rollers. The cutter includes a blocking member and apertures defined therein. The apertures are sized for receiving the stem therethrough and the blocking member is positioned and configured for blocking a passage of the plant portions through one of the apertures. The first and second rollers define an engagement region therebetween downstream of the aperture for receiving the stem, and are drivable to rotate in opposite directions in a forward feeding mode to grab the stem at the engagement region and pull the stem through the aperture, such that the plant portions are retained upstream of the blocking member while the stem is pulled through the aperture, thereby causing disengagement of the plant portions from the stem.
