The INTAREMA® TVEplus® and the new ReFresher from EREMA form a highly efficient anti-odour duo. Their respective tasks are clear: the INTAREMA® removes above all the high volatile odour substances during extrusion while the downstream thermal-physical cleaning process attends to the high molecular odour matter.
Remove odours effectively
A typical problem of household waste: it develops intense odours. These are caused on the one hand not only by contaminants adhering to the surface but also by so-called migrated odour substances. The latter are caused by the packaging absorbing the odour of the food, cosmetics or cleaning agents inside it. The substances which migrate like this into the plastic are particularly stubborn.
Removing the entire spectrum of odours again as effectively as possible requires the support of the entire recycling process chain. This includes sorting and washing, plus the mechanical recycling process. Thanks to the effective interplay of the INTAREMA® TVEplus® with the innovative ReFresher technology it is possible to effectively eliminate a considerable amount of these odour substances again.
While the TVEplus® extruder system primarily takes care of the high volatile, low molecular substances, the ReFresher also removes the low volatile, high molecular odour matter.
Risk of odour through wood, paper and rubber
Small pieces of wood, paper – left behind from labels for example – or rubber and silicone contaminants are potential sources of odour, because in conventional processes these impurities can burn slightly during extrusion and in turn transfer the odour to the plastic. The patented TVEplus® extruder system of the INTAREMA® counteracts this odour development in a targeted way.
High volatile, low molecular odour substances are eliminated prior to extrusion and new odours are prevented from developing.
Odour reduction already at the beginning of the process:
high volatile residues are eliminated
The large-volume preconditioning unit ensures a long material residence time at high temperature. In combination with Air Flush technology – which flushes the plastic with a continuous, hot stream of air – and the accompanying degassing, this results in the high volatile odour substances being eliminated prior to extrusion. An additional bonus: high residual moisture in the material vaporises.
Powerful extruder degassing
The reverse degassing and final double venting degassing zone at the extruder are particularly effective and remove any gas inclusions which are still present from the melt. One secret of success of the strong performance here is the homogenisation zone which is located downstream of the filter and upstream of the final degassing and brings the melt to the degassing temperature required for the end product.
Gentle melt treatment and high-performance filtration = effective odour prevention
Gentle melting and a short extruder up to filtration – what is good for the melt quality is also effective against additional odour development. This is because the gentle treatment at a low melt temperature and low shear forces means that impurities such as cellulose (wood, paper), rubber or silicone firstly do not burn and secondly are scarcely reduced in size.
They remain large enough to be easily removed by the Laserfilter – before they can form unpleasant odours. This is intelligent odour prevention, as offered only by the TVEplus® system.
OUTPUT STAGE 1
Perfectly filtered, homogenised and degassed – ideal for a multitude of applications.
An additional bonus when using the continuous quality monitoring system QualityOn: only exactly specified pellets enter the ReFresher.
The remaining, low volatile, high molecular odour substances are removed from the pellets.
The ReFresher cleaning process eliminates odours caused by low volatile, high molecular substances. The technology keeps the pellets at the required temperature at which volatile materials can be discharged quickly and in depth. Particularly energy-saving: the ReFresher uses the system‘s own energy from the pellets which are preheated through the extrusion process. Thanks to the ideal, stable process preparation in the INTAREMA® TVEplus® only relatively short residence times are required inside the ReFresher .
OUTPUT STAGE 2
For even higher quality applications including e.g. automotive, living space and design sectors.
