Latest Patents
One of Rittershaus's latest patents is the coaxial cigarette. This invention features a coaxial tobacco rod composed of a core and a rod periphery that contain different mixtures. The sheaths of the rod core and the rod periphery are made of combustible material, and a filter mouthpiece is provided at one end. The invention specifies that the ratio of the draw resistance of the core per unit length to the packing density lies between approximately 0.13 to 0.27 mm WC cm²/mg, while the rod periphery's draw resistance per unit length to packing density ratio is between about 0.07 to 0.11 mm WC cm²/mg. The filter mouthpiece is preferably a conventional ventilated filter.
Another significant patent involves a drying process aimed at increasing the filling power of tobacco material. In this process, cut and moistened tobacco is conveyed in a drying gas flow, dried within a tubular section, and then separated from the drying gas. The drying gas enters the section at a temperature of at least 200°C and a flow velocity of at least 30 m/sec. The process carefully reduces the flow velocity of the drying gas and the tobacco material to optimize drying efficiency.
