Description
Apparatus and Method for Drying Tobacco Material The invention concerns an apparatus for drying tobacco material according to the preamble of claim 1, and a corresponding drying method.
Such a drymg apparatus is known from EP 0 528 227 Al. Here, the tobacco leaving the separator is discharged via a starwheel airlock. Behind the drier can be mounted a separate cooling apparatus for reducing losses of flavour by cooling the tobacco, avoiding collapse of expanded tobacco and fixing the filling capacity achieved in the flash drier.
It is known from EP 0 895 721 Bl and from DE 100 38 114 Al to form, before the tobacco inlet into the conveying pipe through which the hot gas stream flows, a substantially closed processing chamber by a conveying pipe section defined by two starwheel airlocks arranged one behind the other. In the processing chamber the tobacco condition can be influenced selectively. However, it is desirable to provide further facilities for influencing the tobacco condition.
It is the object of the present condition to provide an apparatus and a method for drying a tobacco material with improved facilities for influencing the tobacco condition.
The invention achieves this object with the features of claims 1 and 9. By the starwheel airlocks arranged one behind the other in the direction of conveying in a conveying pipe section behind the separator, a substantially closed processing chamber is formed behind the separator, making it possible to influence the tobacco condition selectively even behind the flash drier.
This is effected preferably by means of a conditioning medium introduced into the processing chamber, in particular air, steam, water, carbon dioxide, nitrogen or a mixture thereof.
"Substantially closed processing chamber" means, apart from the inlet and outlet openings for the tobacco material, inlet and outlet openings for conditioning medium and other function openings.
Preferably, the conditioning medium is a cooling medium for cooling the tobacco material, for example, in the form of an air, carbon dioxide or nitrogen stream at a sufficiently low temperature. By cooling the tobacco material after the drying process, losses of flavour can be reduced, collapse of expanded tobacco avoided and the filling capacity achieved in the flash drier fixed. A separate cooling apparatus mounted behind can then, if expedient, be dispensed with. By simply providing two starwheel airlocks in a conveying pipe section, therefore, the expenditure on cooling the tobacco material behind the separator can be significantly reduced. In other words, the known cooling apparatus is integrated by simple means in the conveying pipe mounted behind the separator in order to reduce the expenditure.
Preferably, the conditioning medium can also serve to moisten the tobacco material, in particular if the tobacco material is initially overdried m the drying process and then moistened to the desired moisture in the processing chamber by adding water and/or steam. This method can also be employed, for example, to process burley strips. One of the burley toasters mounted behind the drying apparatus can then, if expedient, be dispensed with.
Preferably, the conditioning medium can also serve to apply top flavour to the tobacco material. A flavouring cylinder mounted behind the drying apparatus can then, if expedient, be dispensed with.
In particular, moistening of the tobacco material and/or applying top flavour can preferably be effected by means of a device in the form of a rotating hollow roller with outlet openings for the conditioning medium.
Further advantageous characteristics are apparent from the subsidiary claims and the following description of advantageous embodiments with reference to the attached drawings. They show: Fig. 1: a drying apparatus according to a first embodiment; and Fig. 2: a drying apparatus according to a second embodiment.
The drying apparatus shown in a detail in the figures includes a drying pipe 10 through which a hot gas 29 flows in the arrow direction. The tobacco 13 falls in the arrow direction through a conveying pipe 11 which leads into the drying pipe 10. In the conveying pipe 11 are mounted two starwheel airlocks 14, 15 spaced apart in the direction of conveying and forming between them a processing chamber 16 mounted in front of the drying pipe 10. In the wall of the conveying pipe section which forms the processing chamber 16 is provided an inlet 17 for introducing a conditioning medium 18 into the processing chamber 16. Preferably, an outlet 19 for extraction of the conditioning medium 18 is also provided. By arranging the inlet 17 behind the outlet 19, the conditioning medium 18 in the processing chamber 16 flows in counter-current to the tobacco 13.Behind the starwheel airlock 15 on the output side can be provided a conditioning device 20, for example, in the form of a rotating winnower roller with hollow shaft and/or hollow pins and corresponding nozzle openings through which conditioning medium is sprayed into the conveying pipe 11. Behind the conditioning device 20, the tobacco falls into the drying pipe 10 and is there taken up, entrained and dried by the hot gas stream 29.
The dried tobacco is separated from the hot gas stream 29 in the separator 12. The tobacco falling out of the separator 12 falls into a subsequent conveying pipe 21. Immediately behind the separator 12 a starwheel airlock 22 is mounted in the conveying pipe 21. Immediately behind the separator 12 means that no further device for processing the tobacco is mounted between the separator 12 and the starwheel airlock 22. However, a short conveying pipe section can be provided between the separator 12 and the starwheel airlock 22.
Behind the starwheel airlock 22 in the conveying pipe 21 is mounted a further starwheel airlock 23. Due to the distance between the starwheel airlocks 22, 23, a processing chamber 24 arranged behind the drying pipe 10 is defined in the conveying pipe 21. In the wall of the section 25 of the conveying pipe 21 which forms the processing chamber 24 is provided an inlet 26 for introducing a conditioning medium 27 into the processing chamber 24. Preferably, an outlet 28 for extracting the conditioning medium 27 is also provided. Due to the arrangement of the inlet 26 behind the outlet 28 in the direction of conveying, the conditioning medium 27 in the processing chamber 24 flows in countercurrent to the tobacco 13. The conditioning medium can be, for example, a gas stream, in particular air, carbon dioxide, nitrogen or a mixture thereof, for cooling the tobacco.By this means losses of flavour can be reduced, collapse of expanded tobacco avoided, and the filling capacity achieved in the flash drier fixed. Preferably, the gas stream 27 has a low enough temperature for cooling the tobacco approximately to room temperature. Further conditioning means, for example, steam and/or water, can be added to the gas stream 27.
Introduction of the tobacco into the drying pipe 10 can also be effected in a different manner to the one described. In particular, within the scope of the present application the processing chamber 16 formed by means of the starwheel airlocks 14, 15 and mounted in front of the drying pipe 10 is not absolutely imperative.
The downstream starwheel airlocks 22, 23 can be designed with a permanent pressure difference to allow processing in the processing chamber 24 with an overpressure of more than 1 bar. This is, however, not absolutely necessary. The same applies to the upstream starwheel airlocks 14, 15.
In the embodiment in Fig. 2, in the downstream processing chamber 24 is provided a conditioning device 30, for example, in the form of a rotating winnower roller with hollow shaft 31 and pins 32 and corresponding nozzle openings in the hollow shaft 31 and, if expedient, in the hollow pins 32, through which conditioning medium 33 is introduced into the processing chamber 24. The conditioning medium can be, for example, water for moistening the tobacco, in particular in connection with overdrying of the tobacco in the drying pipe 10. In another application the conditioning medium can be, for example, top flavour, so that a flavouring cylinder mounted downstream can under certain circumstances be eliminated. Other conditioning media can be introduced if required.
The conditioning device 30 mounted behind the separator 12 does not necessarily have to be arranged in the downstream processing chamber 24. Also conceivable is, for example, an arrangement of the conditioning device 30 behind the starwheel airlock 23 on the outlet side, similar to the arrangement in the conveying pipe 11 at the tobacco inlet into the drying pipe 10.
