EREMA Plastic Recycling System with high performance degassing type TVE
Erema TVE extruder design: superior degassing efficiency In various cases (when processing particularly strongly printed, heavily contaminated and/or wet plastic waste) we experienced that conventional degassing extruders do not meet today's requirements in daily recycling practice. This prompted Erema to develop a unique, patented technology: the TVE-extruder design of Erema with melt filter upstream of the extruder venting.
The simple yet superior design of this plant combines optimum degassing with finest possible filtration. This rules out the well-known disadvantages of conventional degassing extruders, e.g. limited ability to overcome pressure, sensibility to clogged screens, insufficient degassing, which may even be too low for further processing (particularly in the case of heavily printed or heavily contaminated feeding material).

The optional touch screen control enables the recording of production data, operation of plant via control room and on request (via modem) online support through the Erema Technical Centre.

The technical features
- Optimum degassing efficiency:
- Contaminants that tend also to
form gas downstream of the degassing zone in the case of conventional
degassing extruders, are filtered upstream of the degassing zone
already.
- Any gas inclusions in the melt that are caused by
filtered, decomposing contaminants upstream of the filter screens, are
removed in the subsequent degassing zone of the extruder.
- Only
completely molten polymer material can pass through the degassing zone
of the extruder. Any unmelted polymer components remain in the section
upstream of the melt filter until they are completely molten. - Peak
pressure rates, which are caused by filters becoming clogged by sudden
high concentrations of contaminants, do not adversely affect the
degassing efficiency (no risk of melt leakage at the degassing outlets
as with conventional degassing extruders).
- No undesired air pockets in the melt upon screen change, which may be conveyed to the die head.
- Reduced wear as the contaminants, if any, are already separated in the middle of the extruder.
- Well proven system, more than 400 delivered worldwide (2004).
The economic benefits
- High-quality, perfectly degassed end product
- Largely maintenance-free – low service costs
- Compact, space-saving design
- Optional touch screen control, which widely increases plant productivity
