  • Patent number: 9999892
    Abstract: A method and apparatus are provided for processing whole tobacco plants. The method includes cutting the whole tobacco plants into segments in a segmenter assembly, classifying the segments by leaf characteristics, separating leaf material from a waste material stream of undesirable stalk and shatter material for each class of leaf characteristics and reclaiming portions of leaf material trapped in the waste material and recycling the reclaimed portions of leaf material to the segmenter assembly. The apparatus includes a stalk segmenter assembly, a processor assembly, a plurality of cleaning conveyor modules and a cyclonic separator system to reclaim small bits of leaf from the waste stream and return them through a rotary airlock to the segmenter assembly for reprocessing.

  • Patent number: 7980048
    Abstract: A mechanism for harvesting tobacco plants includes a magazine of rails. Each rail is elongated and hollow, with a slot along a bottom portion of each rail. Two opposing dispensing conveyors each engage opposing ends of each rails for advancing an empty rail to a filling position. Two opposing notching conveyors grasps the plants and cuts notches into the plants on opposing sides of the plant. A single roller chain stepping conveyor moves the plants from the opposing notching conveyors into a rail in the filling position. The two opposing dispensing conveyors advance the rail filled with plants. An unloading conveyor having opposing roller chains receives the rails filled with plants, collects a group of filled rails, and unloads the group of filled rails on a ground level at a linear speed equal to a forward speed of the harvesting mechanism.
