Stem Die Type Patents (Class 131/323)
  • Patent number: 11986833
    Abstract: A hemp flower, bud, and leaf material stripping machine having a housing, a motor and gearbox that drive a pair of rollers inside the housing, an adjustable locking shaft that adjusts and maintains a space and pressure between the rollers, and a series of feed holes of different diameters on a front side of the housing. Each feed hole is constructed to strip flowers, buds, and leaves from a hemp stem as the stem is inserted into a feed hole and is pulled through the feed hole by the rollers. The flowers, buds, and leaves are severed from the stem at an exterior of the front side of the housing, without damage to the flowers, buds, and leaves. The feed hole is constructed with close tolerance so that the stem can pass through the feed hole but the flowers, buds, and leaves cannot. Hemp stems are stripped in seconds. The flowers, buds, and leaves are not crushed, cut, torn, or compressed as they are severed and fall into a container.
