A method of treating tobacco material including combining pre-cut and/or pre-expanded stem with lamina to form an initial combination of stem and lamina; cutting the initial combination of stem and lamina; expanding the combination of stem and lamina; and intermittently contacting the expanded combination of stem and lamina with a heated surface to produce a treated tobacco material. An apparatus is also provided for treating tobacco material. Also provided is a treated tobacco material, as well as products including the same.

A cigar tobacco strips and a method for rolling and packaging the same is provided. The cigar tobacco strip is rolled into cylindrical shape and placed within an enveloping means. The tobacco strip is wrapped into cylindrical form causing the cigar tobacco paper to form a plurality of layers, wherein said layer comprises a double strip section. The rolled tobacco strip is then placed inside an enveloping means. The encased tobacco strip within the enveloping means allows for the tobacco strip to keep a cylindrical shape until delivered and used by a consumer. The enveloping means may maintain the moisture for longer time due to the rolling method prior to delivery to a consumer.

A stem screening and conditioning device includes a roller, a thermal insulation cover, a spiral feeding device, a compressed-air cleaning device, a steam tube, a discharge hole, and a waste hole. A stem screening and conditioning method for the stem screening and conditioning device is also provided. The present disclosure realizes the complete separation of normal-size and undersized stems under the premise of full moisture absorption, thereby improving the refinement and homogenization level of stem conditioning.

A method for producing reconstituted tobacco includes comminuting the solid components of tobacco to a particle size of about 20-220 μm; mixing the comminuted tobacco product with water, at least one binding agent and at least one material to form an aerosol until a mixture with a liquid content of about 30-50% is obtained; subjecting that mixture to a first lamination to obtain a strip of continuous thickness of about 1-20 mm; subjecting the strip to additional rolling passages to obtain a strip having a substantially constant thickness of approximately 90-280 μm; and drying the strip to bring its liquid content to about 8-15%.
