INTAREMA TVEplus

The patented extruder system enables trouble-free processing of materials that are otherwise difficult to process. Such as heavily printed films and very moist materials. Ultrafine filtration, melt homogenisation and high-performance degassing are performed in a single step. The innovative basic principle of TVEplus^®is: 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.

Possible materials

It's amazing what you can recycle with INTAREMA^® TVEplus^®. Here are some examples.

Heavily printed / metallised films

LDPE washed flakes, agricultural film

PE film with paper labels, pallet wrap

PE washed film flakes (e.g. DSD310)

PP film / non-woven fleece with solid content

Your benefits

Economical and technically better.

Enhanced material intake, greater flexibility, higher throughput thanks to Counter Current^®

Extremely easy operation and maximum user-friendliness with Smart Start^®

High-quality end product even with materials that are difficult to process

Enhanced filtration performance – thanks to reduced shearing upstream of the melt filter

Up to

12%

lower energy consumption, lower production costs and CO2 emissions thanks to ecoSAVE^®

Optimised triple degassing with the preconditioning unit, optimum screw design and extruder degassing

Much higher output rates with the same screw diameter compared to conventional degassing extruders

Greater homogenisation efficiency downstream of filtration and upstream of degassing enhances the degassing performance and improves the characteristics of the melt

Compact, space-saving design

How it works

INTAREMA^® TVEplus^®

Feeding (1) is automatic and 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 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, the melt is conveyed to the respective tool (8) (e.g. pelletiser) at extremely low pressure with the help of the discharge zone (7).

OPTIMISED TRIPLE DEGASSING

Initial degassing in the EREMA preconditioning unit takes place through preheating and pre-drying the material. The optimum screw design - tuned to the material to be processed - enables reverse degassing in the preconditioning unit, thus relieving the degassing zone of the extruder Gas inclusions in the melt are removed in the extruder degassing zone. Only thoroughly melted, filtered and homogenised material can pass the degassing zone of the extruder
