Las bandas de procesamiento primario deben ser duraderas y altamente resistentes a las cáscaras y lÃquidos aromáticos. También deben emitir poco ruido, ser fáciles de limpiar y tener una larga vida útil.
At Ammeraal Beltech, we have belts with all these characteristics and more; belts with high friction and low friction coefficients, with profiled surfaces, with operating angles of up to 40°, able to trough and with the high lateral flexibility to prevent tobacco dust from spilling.

Actual factory and process configurations could vary, but our industry experts know them all.
Para este proceso, las bandas deben ser resistentes a los golpes y tener los coeficientes de fricción correctos para mantener los bloques de tabaco seco en posición sobre la superficie de la banda.
Main challenges
- Dusty circumstances
- Slippage of bales
Solutions
- Ammeraal Beltech fabric belts demonstrate good wear resistance in this application
- Amtel polyester belts provide just the right friction coefficient
Los bloques de tabaco grandes se cortan en rebanadas en un sistema de guillotina automático. Esta operación puede tener lugar en una banda o entre dos bandas.
Main challenges
- The blade hits the belt and cuts it, reducing lifetime
- The impact from heavy falling slices disrupts belt performance
Solutions
- Ammeraal Beltech has durable cut-resistant belt surface solutions available
- Impact-resistant belts remain unaffected by such concussive forces
In this step, the slices are taken on incline conveyors to the first DCC (Drum Condition Cylinder). Here the brittle leaves are treated with heat and steam to make them flexible again. Additional fluids (to add flavours) may also be present.
Main challenges
- Delamination of the belt can occur
- Heat can shorten belt lifetime
Solutions
- Amtel belt lamination is not affected by application temperatures or humidity levels
- Amtel belts are temperature resistant
- For incline feeding conveyors Ammeraal Beltech offers special easy to clean profiles
Durante el procesamiento de hojas verdes, NTM (material sin tabaco) ya se ha extraÃdo manualmente. Durante el procesamiento primario, las empresas usan equipo de escaneo de alta tecnologÃa para las partes más pequeñas. La detección se basa en las diferenci
Main challenges
- Discolouration of the belt over time
- Colour mismatch issues
Solutions
- Ammeraal Beltech has colour-fast belts for this application
- Poliflex and Polikleen belts have stable standard colours for different processing requirements
El alimentador se usa para transportar tabaco a los transportadores del silo de mezclas.
Main challenges
- Perforated belts can snag and tear
Solutions
- Ammeraal Beltech’s solid-carcass polyester belt won’t tear
La mezcla de distintos tipos de tabaco en función de las recetas precisas para producir una mezcla caracterÃstica y homogénea.
Main challenges
- Tracking issues at the shuttle belt above the silo
- Too much sticking tobacco on the silo belt (chain or drum-driven solution)
- Belt pollution
Solutions
- Ammeraal Beltech Ultrasync products with polyester coating for good tracking properties
- Tobacco proof scraper solutions to face the belt pollution
- Our silo belts for less sticking tobacco
El tabaco mezclado es cortado en pequeñas tiras. Durante este paso se libera gran cantidad de fluidos provenientes de las hojas de tabaco.
Main challenges
- Tobacco builds up very quickly on the belt
- Tobacco fluids penetrate the belt surface
Solutions
- The Ammeraal Beltech Polikleen Belt resists build-up and absorption
En este tipo de aplicaciones, es fundamental tener el diseño de sistema de bandas correcto: la banda se desplaza bidireccionalmente en un sistema de raÃles.
Main challenges
- Mistracking
Solutions
- A positive drive Ultrasync or Soliflex solution will help prevent mistracking
El paso final del procesamiento primario es el almacenamiento en silos del tabaco cortado, bien mediante accionamientos por tambor o por cadena. Todos los silos operan lentamente y la vida útil de sus bandas es larga (10+ años).
Main challenges
- Tobacco adhering to belt
- Sourcing belts that are wide enough
Solutions
- Impregnated silo belts counteract tobacco build-up
- Solutions for both drum-driven and chain-driven systems come in widths up to 5 m
En el procesamiento primario, los transportadores tienen faldones laterales a prueba de tabaco (para evitar la acumulación de tabaco entre la banda y el transportador) y cortinas (para evitar contaminación).
Main challenges
- Single-side coated curtain material can curl
Solutions
- One-ply dual-side coated curtain material will not curl
- Different approved side skirt materials
