PET recycling line OMNIboost

reactor

Gneuss’ OMNIboost series is a PET recycling system specifically designed for recycling polyester waste for applications with high viscosity requirements. This PET recycling machine builds upon the well-known OMNI series with an MDS extruder and complements it with a Gneuss JUMP reactor, which, in combination with a specially designed vacuum system, allows a significant increase in viscosity. Applications for this PET recycling machine include PET bottle-to-bottle recycling and recycling of polyester waste with widely varying input viscosities, such as in the recycling of fiber waste. Design of the OMNIboost PET recycling system 3C Rotary Feeder The newly developed 3C Rotary Feeder enables processing of low bulk density materials without external processing steps. A conveyor belt feeds shredded reclaim into the hopper where a high-speed rotating disc with knives cuts, compacts and pre-treats the material. The knives feed energy to the material and start the heating and degassing process before the material is automatically fed into the extrusion system. Extrusion system The OMNIboost recycling machine uses the new and patented MDS extruder, which is characterized by alternating screw diameters and a novel interaction of heat input and degassing. The basic concept of the MDS is to briefly thermally charge the melt before it enters the degassing zone, thus achieving an enhanced degassing effect. This is realized by widening the screw diameter at the end of the metering zone, followed by a long deep-cut degassing zone with a likewise widened screw diameter. The result is a highly efficient degassing performance with gentle melt handling. The system’s robust and flexible
