Bottle to Bottle Recycling Plant
Categories : Recycling Lines by Application
- Features of Extruder: This new extrusion system brings together the familiar superior plasticization and homogenization of a parallel twin-screw extruder with the specific advantages of the conical twin-screw system. The screw is equipped with easy changeable shear and mixing elements which allow adjusting the plasticizing exactly to each demand. Effective degassing supported by a vacuum pump removes monomers in the front of the plasticizing unit • Big intake section / very good in-feed behavior • Conical design ensures very good screw filling • Therefore, high output per screw rotation (kg/rpm) • High torque possible because of huge screw shaft diameter • Very stable pressure behavior • Excellent homogenizing offered by the co-rotating system • Excellent feeding performance • Small melt dwell time distribution inside the processing unit • Therefore low melt temperature • Therefore low energy consumption - Features of SSP In the SSP process, the PET pellets are further decontaminated and their molecular weight is increased to obtain high-quality bottle grade resin, which meets the regulations of the authorities and requirements of the packaging industry. SSP and decontamination of migrated substances are diffusion controlled processes. The main design parameters are product temperature and residence time. The solid-state polycondensation process (SSP) is required to upgrade the molecular weight of the amorphous PET pellets to high-quality bottle grade resin, which meets the regulations of the FDA and requirements of the packaging industry. • Especially suitable for small and medium enterprises in the third world countries which has no polymerization facility. • High I.V. chip downstream users • Stable performance, economic investment and high C/P value. • Long-term experience and quality control method of washing line will provide excellent and stable quality of PET flakes for continuous and stabilized feeding of pelletizing and SSP. • Energy-saving and environmental-friendly: reuse heat energy from pelleti
Food Grade PET Bottle Recycling Line
Categories : Recycling Lines by Application
The food-grade PET bottle recycling line is mainly used for PET bottle-to-bottle project (FDA Approval), which recycles post-consumer PET bottles into rPET flakes. The regenerative PET flakes conform to the quality index requirements of downstream food packaging and are used for bottle blowing and packaging which can directly contact food after pelletizing and SSP processes in the late stage. The food-grade PET bottle recycling process is more complicated than normal PET recycling, and the requirement for equipment and the quality of the final rPET flakes are more strict. At the same time, the owner is required for higher factory management and advanced production knowhow. BoReTech food-grade washing line has higher automation to avoid human errors. Ultra-cleaning of PET bottles and flakes, efficient blending, and an online inspection system to ensure that the output of recycled PET flakes meets the standard of food-grade PET bottle-to-bottle process (FDA Approval). Meanwhile, the BoReTech food-grade PET bottle recycling system process is optimized according to the post-consumer PET bottle condition from different countries with the economic cost, less space occupation, and the most advanced process technology to meet the variety of downstream production applications. With more than 20 years of experience in PET bottle recycling production, BoReTech provides online production and process guidance to customers. BoReTech PET bottle recycling system adopts a SCADA system combined with a PLC controller, which can display parameter data of each unit and single equipment intuitively and effectively, and at the same time the system can record all production data, and it has combined the remote communication technology to allow communication between customers and BoReTech engineers by the internet and give them real-time guidance. BoReTech can assist customers with practical production management, data analysis, and equipment daily maintenance. In addition, the entire PET bottle system is equipped with an optical bottle sorter and flake sorter, which greatly reduces the investment of labor and improves production efficiency, thereby truly achieves a highly automated and clean recycling system. PET bottle bales are sorted, crushed, and washed by the food-grade PET bottle washing line, and finally generated high-quality rPET flakes. A number of well-known customers of BoReTech have obtained FDA approval of rPET flakes and supply these PET flakes to downstream brand beverage manufacturers. BoReTech analyses post-consumer PET bottles from various countries and is developing a short (compact)-process PET bottle recycling system for these post-consumer PET bottles in specific countries and regions. The developing system integrates multiple functions of a single machine and greatly reduces space occupation and investment. rPET flakes recycled by compact line can also meet the requirement of the food-grade application and micro-denier filament grade applications. It will be launched at the end of 2020.
