A method of reducing the amount of matrix-bound NNK in cured tobacco plant material is provided comprising reducing the amount of lignin in the cured tobacco plant material. A further method of reducing the formation of matrix-bound NNK during the curing of tobacco plant material is described comprising reducing the amount of lignin therein prior to curing.

A system for removing biomass from a stem includes a frame, a conveyor mechanism which moves the stem in a horizontal conveying direction, a pair of rollers which exert a rubbing force between each other for removing the biomass from the stem, and a tensioning system arranged to exert a force which holds the stem to the conveyor mechanism. A first axial end of each roller is connected to an inlet end side of the conveyor mechanism, and a second axial end of each roller is connected to a transmission such that the rollers are angled downward from the first axial ends to the second axial ends. The conveyor mechanism moves the stem so as to pass between the rollers such that the rubbing force removes the biomass from the stem, and such that the rubbing force moves downward along the stem as the stem moves in the conveying direction.

A method of treating tobacco leaves for separating the lamina from rib, includes: collecting the leaves in mannochi, and subjecting them to a shredder, where portions of the lamina of each leaf are torn from the remaining part of the leaf, separating portions of lamina from the remaining part of the leaf, by air, in at least one classification chamber, directly transferring portions of torn lamina to subsequent drying and packaging processes, passing the remaining parts of the leaf through a multi-stage beating line, in each of which progressive separation of portions of the lamina from the remaining part of the leaf is caused or to obtain at the exit of said beating line, an almost total separation of the lamina from the rib, transferring the separated portions of lamina to subsequent drying and packaging processes, transferring the pieces of rib exiting the beating line to the packaging.

The invention relates to a method for stripping leaves and/or flowers from a stalk (1), in particular for stripping cannabis leaves and/or cannabis flowers from a stalk (1). Thereby, a loop (2) is formed around the stalk (1) to be stripped, which is formed at least in a partial area from flexurally elastic or flexurally slack loop means (3, 3a, 3b) which have tensile strength in the direction of the loop. The stalk (1) is then pulled through the loop (2) in the longitudinal direction of the stalk, with the leaves and/or flowers being stripped from the stalk (1). The invention makes it possible to strip the leaves or flowers, respectively, more easily and directly from the surface of the stalk (1), such that they can be substantially harvested better, faster and with less damage. Less preparatory work is also required.

One embodiment of the present invention relates to a system for cannabis stem harvesting configured to specifically separate the leaves and buds from the stem. The system includes a frame member, die member, first rotating cylindrical member, second rotating cylindrical member, and a rotation system. The die member is coupled to the frame member and includes a plurality of orifices disposed within a plate. The first and second rotating cylindrical members are coupled to the frame member in a vertical configuration and oriented substantially adjacent to the die member. The vertical configuration of the first and second rotating cylindrical members defines a pinch region therebetween as a region across which a first and second circumferential surface of the first and second rotating cylindrical members are closest in proximity. The rotation system is coupled to the frame member and at least one of the first and second rotating members.

A leaf removal assembly including a frame comprising a front plate having a feed opening, a leaf stripping assembly mounted on said front plate in front of said feed opening and an upper sprocket wheel comprising a plurality of upper socket grippers extending radially outward of the upper sprocket wheel and being disposed behind the front plate. The leaf removal assembly further includes a lower sprocket wheel comprising a plurality of lower sprocket grippers extending radially outwardly of the lower sprocket wheel and being disposed behind the front plate. At least one of the upper sprocket wheel and the lower sprocket wheel may be adjustably attached to the frame. A process for separating a leaf from a stalk comprising at least one leaf is also included.
