A method and a device for distributing cut tobacco for feeding cigarette-making machines. The distributing device is equipped with a distribution chamber having a bottom, with a feeding channel for feeding the cut tobacco to the distribution chamber, the channel being connected to the chamber from above, with at least one receiving channel for receiving the cut tobacco from the distribution chamber, the receiving channel being connected to the chamber at side walls thereof. A rotary element for changing local bulk density and disturbing the flow of the cut tobacco fed to the distribution chamber is eccentrically mounted to a stationary bottom of the distribution chamber.

Method and device for distributing cut tobacco for feeding cigarette-making machines

A system is used for removal of impurities from shredded tobacco recovered from defective cigarettes, especially activated carbon particles, as used in a machine for recovering tobacco and having separating sieves and suction devices, where in a transport zone for a mixture of shredded tobacco, paper and impurities, positioned directly downstream the device for final tearing of the cigarette paper, with the zone defining a turbulent flow zone for the mixture of shredded tobacco, paper and impurities, a separating device is installed which defines a first purification zone. The device has a grid, a vacuum system for maintaining turbulent flow of the mixture of shredded tobacco, paper and lightweight impurities, positioned above the grid having a mesh size larger than the size of heavy impurities, and a vacuum system for receiving heavy impurities. Then a second purification zone includes a vibrating sieve with a mesh size larger than the size of heavy and lightweight impurities. A vacuum dust removing device, defining a third purification zone, has a transport pipe with flow disturbing elements, a rotational sieve having a grid of a mesh size suitable for suction of volatile impurities, a flow guide means adjacent the sieve and defining at the same time a flow disturbing element, and a rotary chamber valve positioned under the sieve.
