INTAREMA - Model TVEplus - Extruder System
The patented extruder system INTAREMA TVEplus sets new standards in the recycling of materials that are difficult to process such as heavily printed films and/or very moist materials. This is made possible through ultrafine filtration, thorough melt homogenisation and high-performance degassing in a single step. The proven basic principle of TVEplus technology: melt filtration takes place upstream of extruder degassing. As a result, end products can be produced with the best quality and the highest possible recyclate content.
- Enhanced material intake, greater flexibility and higher throughput rates thanks to Counter Current technology
- Optimised triple degassing with the patented EREMA cutter/compactor, optimum screw design and extruder degassing ensure highly effective degassing of the filtered melt
- Reduced shearing before the filter improves filter performance
- Greater homogenization efficiency downstream of filtration and upstream of degassing enhances the subsequent degassing performance and improves the characteristics of the melt
- Innovative, patented additional technologies for the EREMA cutter/compactor – DD system and Air Flush module (optional) widen the scope of application
- High-quality end product even with materials that are difficult to process such as heavily printed films and/or very moist materials; end products can contain a considerably higher share of recycled pellets
- Extremely easy operation and maximum user-friendliness with the Smart Start principle
- ecoSAVE reduces energy consumption by up to 12 % as well as production costs and CO2 emissions as a result
- Considerably higher outputs with the same screw diameter compared to conventional degassing extruders
- Compact, space-saving design
Feeding (1) is automatic according to customer requirements. In the Preconditioning Unit (2) the material is cut, mixed, heated, dried, pre-compacted and buffered. Next, the tangentially connected extruder is filled continuously with hot, pre-compacted material. The innovative Counter Current technology enables optimised intake action across an extended temperature range.
In the extruder screw (3) the material is plasticised and degassed in reverse. At the end of the plasticising zone the melt is directed out of the extruder, cleaned in the fully automatic, self-cleaning filter (4) and returned to the extruder again. The final homogenisation of the melt (5) takes place after the melt filter. In the subsequent degassing zone (6) the filtered and homogenised material is degassed. Following this, and with the help of the discharge zone (7), the melt is conveyed to the respective tool (8) (e.g. pelletiser) at extremely low pressure.
