Process and stripping plant sub stripping of tobacco by Chopping Hit Subsequent Sifting

The invention relates to a method sum of stripping ron tobacco by Shredding old subsequent * siftings, in which the tobacco is stripped several times in succession, and the mixture that arises after each stripping is then sifted through Leaves separated by the ribs.

In the known methods, the sight air is set so that largely pure sheet material is calibrated. This sheet material contains a rather small amount of hip error, which is approximately between 0.3 and 1 + . The greater the rib centerline in the material to be seen, the more difficult it becomes because the material that is falling is essentially excluded from the sheet material Large parts of the leaf material that are carried along by clusters and ribs with leaf are entrained. The leaf parts that are carried away, which are now shredded in the near-streaked bat, consist of large leaf parts. However, economic considerations are required, isj AtY part of the leaf material which is less old IA "is reached sin minimum and the sheet material a familiar sheet share ren over 1" contains.

The task of the invention is ta, including such sheet material from dtm Misohsohwergut to be sifted out before the next stripping, This is also due to multiple viewing of the Misohsohwerggut the heavy cargo concentrate present in Misohsohwergut not can be raugeeiohtet.

In a preferred embodiment of the method according to the invention, in which the mixed material obtained after the first stripping is sifted several times before the second stripping, it is provided that the heavy material of high rib concentration remaining after the first stripping after prospecting of sheet material by a subsequent pre-sifting immediately before the "extensive stripping in miso-light material, low rib concentration," etation and heavy material, and this miso-light material is subsequently separated by a compartment sloping into heavy light material and light so-called material, after which the close prospect of the heavy light material from the miso-light material flow together with the remaining light so-called material together with the Pre-Siohten accrued is fed to the second Entrlppstufe. By this pre- and post-Siohten immediately before the second Entrippen the proportion of ausgesiohteten sheet material with low Rippenfehlaustrag is considerably increased, and it is particularly wiohtig, thereby significantly reducing the proportion of the small sheet pieces less than 1 ^N and the leaf proportion of large pieces of leaf via 1 ^{N is} increased considerably.

It is well known that when sifting with very high power, one has a worse degree of efficiency than when sifting with low power, because of the required uniformity of the air flow only a limited enlargement over its entire cross-section this cross-section is possible. With the high visibility requirements that are required today, the air flow has a higher degree of filling required, which leads to a poorer visual result. at According to the method according to the invention, a partial flow of goods from the main flow of goods to be classified is branched off, namely those components that are difficult to separate. The sheet material can be used from this partial material flow be aligned with high efficiency because the amount of material and the rib concentration in the partial material flow is significantly lower as the crop quantity and the rib concentration in the main crop flow.

Because of the low power required for Haoh-sifting the Misohle! ent good is required, one can in further development the invention provide that the Miso light goods of low rib concentration in a floating air stream in sohweres Leiohtgut and light heavy cargo is separated. 909882/0127

The feeder 53 continuously demands a uniform amount of ron Tobacco leaves to the Vorentrippvorriehtung 4 »and about 6800 kg per hour. The following numerical values for the output per hour, which are mentioned to better illustrate the process, are rounded, approximate numerical values, as they are approximately achieved in practice with the method according to the invention * The 6300 kg of tobacco leaves consist of 5035 kg sheet material and 1765 kg tilting. With sheet material weighing 5035 kg, you have very good visibility results when you are in the doorway Rib misalignment of approx. 15 kg (0.3 ^). In this way, 5050 kg of light material are used to view the entire sheet material and 1750 kg of dumps separated as waste. The tobacco leaves are stripped in the Entrippvorriohtung 4 and the resulting Mixed material, consisting of 4400 kg light material and 2400 kg heavy material, fed to the hopper 60. The material to be mixed is conveyed into the sifting device 6 via the pneumatic conveying line 62 and sifted. Here, 2350 of the 4400 kg of the light goods are sifted out and via the Grleiohstroiagutteilabführung conveyed into the Gleiohstromgutabführung 34.

Since the mixed light material that is sifted in the floating viewing shaft 28 has a very high concentration of light material, 450 kg of light material are sifted and conveyed away via the constant material discharge 33. Aue the end of the floating ditch, which is open at the bottom, only the 50 kg light heavy goods and the 50 kg light goods that are aligned in the front-sighting device 10 fall onto the conveyor belt of the counter-flow goods discharge 32, on which the mixed heavy goods with a high concentration of heavy goods from the front-sighting device 10 are lying. The entire mixed heavy material, which now consists of 100 kg light material and 2400 kg so heavy material »is fed to the stripping device 12 by the feeder 64. As a result of the further stripping, a further 350 kg of light goods are released, so that 450 kg of light goods and 2050 kg of heavy goods are conveyed into the sifting device 14 through the pneumatic conveying line 70. In this viewing device 14, a further 300 kg of light goods are thinned out and removed via the same cargo discharge 40. The remaining 150 kg light goods and 2050 kg heavy goods fall into the hopper 3C and are conveyed into the viewing device 16 through the pneumatic conveying line 36.
