The online measuring of melt volume-flow rate (MVR) takes place likewise directly at the machine. Unlike well-known online viscosity measuring systems which use gear pump technology and are designed primarily for clean polymers in the virgin material sector, the MVR measuring unit is designed especially for the higher requirements of recycling processes. It is, for example, insensitive to extremely small contaminant particles of 100-1,000 μm which are common in post-consumer recycling.
Post-consumer material, especially household packaging waste, is considered to be plastic which is difficult to recycle due to impurities and the fluctuating degree of contamination. These contaminants often cause an unpleasant odour in the recyclates which severely limits the scope of use with the end products. The ReFresher eliminates odours caused by migrated substances, i.e. residues left on the plastic materials. These include, for example, food contamination, cleaner/detergent residues and cosmetics. The ReFresher is downstream of the extrusion process and keeps the recyclates at the required temperature at which volatile materials can be discharged. The ReFresher is available in various expansion stages depending on the end application.
