Definitions
- This invention relates to a separator for shredded tobacco according to the preamble of claim 1.
- a separator of this kind is already known from FR-A- 2543 456.
- the processing of shredded tobacco comprises a separation stage in which the shredded tobacco is treated both to separate it from the air and to separate foreign bodies from it such as stones, tobacco agglomerations etc.
- This stage is currently carried out using a separator consisting of a casing provided at its bottom with a rotary valve for discharging the tobacco and at its centre with a rotating mesh cylinder or other system for withdrawing the air to be fed to the filter.
- the object of the invention is to eliminate these drawbacks by providing a device which enables the separation to be effected in a simple, comfortable and reliable manner, without the product undergoing "manipulation".
- the separator of the invention comprises substantially a vertical column 2 of rectangular cross-section provided with a connector for an entry duct 4 for the shredded tobacco and a perforated plate 6 inclined towards a duct 8 for discharging waste such as stones, tobacco agglomerations, etc.
- the column is connected at its bottom to a pipe 10 for feeding compressed air originating from a centrifugal blower 12.
- a dome 14 housing a mesh conveyor 18 extending about drive and deviation rollers 20, a horizontal portion 22 of the conveyor 18 being positioned substantially to close the mouth of the column 2.
- An air withdrawal hood 16 is present above the horizontal portion 22 of the conveyor 18.
- the dome 14 presents an inclined lower part 24, the upper side of which can be adjusted so that it lies substantially in contact with the conveyor, its lower side being substantially in contact with a discharge belt 26.
- a compressed air diffuser pipe 30 is provided facing that portion of the conveyor 18 downstream of the portion 22 which closes the mouth.
- the separator of the invention operates in the following manner: the shredded tobacco fed by the conveyor belt 34 is transferred through the duct 4 to the interior of the column 2, where the suitably regulated compressed air flow feeds the tobacco particles towards the conveyor 18 while allowing the foreign bodies such as stones and tobacco agglomerations to deposit by gravity onto the perforated plate 6 and then descend towards the discharge duct 8.

Claims (3)
- A separator for shredded tobacco comprising a column (2) provided at its bottom with a perforated plate (6) inclined towards a discharge duct (8), and further provided with an entry duct (4) for the shredded tobacco and a feed pipe 10 for air which propels the shredded tobacco upwards, characterised in that the upper mouth of the column faces a mesh conveyor (18) movable substantially transversely to the vertical axis of the column, said conveyor forming an element by which the upward rise of the shredded tobacco is halted and is conveyed towards a member (30) for removing and conveying the tobacco.
- A separator as claimed in claim 1, characterised by comprising a suction system (16) situated in a position overlying the conveyor belt.
- A separator as claimed in claim 1, characterised by comprising a compressed air diffuser pipe (30).
