Coperion has equipped its ZSK 18 MEGAlab laboratory extruder with numerous new functions that provide significantly greater flexibility and safety in handling. Pluggable cartridge heaters instead of hard wired ones now allow for rapid barrel reconfiguration as well as straightforward cartridge heater exchange. An electrically securable maintenance door on the gearbox lantern increases operational safety and at the same time provides quick access, reducing downtimes for screw changes and system maintenance. Moreover, feeders for this laboratory machine can now be placed on a newly developed patent-pending feeding platform which allows up to four feeders to be arranged with maximum flexibility for adding ingredients in myriad ways.
The ZSK 18 MEGAlab, with a screw diameter of 18 mm, has a specific torque of 11.3 Nm/cm³ and achieves a maximum rotation speed of 1,200 min-1. It is ideally suited for use in research and development projects as well as for production of minimum quantities.
Optimized feeding platform
The new, patent-pending feeding platform makes adding ingredients noticeably easier. It is firmly attached to the ZSK 18 MEGAlab extruder, allowing for flexible positioning of up to four feeders on all barrels of the process section as well as on the ZS-B side feeders. Moreover, the new feeding platform, which can be moved laterally along the machine, allows the feeders to be rotated and raised or lowered as needed. This feature creates enormous advantages particularly in the areas of research or recipe development, since feeding can be located flexibly at various points, in accordance with the process requirements. Elaborate, costly reconfiguration tasks and cumbersome additional frames for feeders are a thing of the past. Moreover, cleaning is simplified since the feeder can simply be pivoted away from the process section, thanks to the new platform. Where the previous model required a separate frame for each feeder, now up to four feeders can be mounted on the new platform. Time-consuming solutions for mounting additional feeders, or reconfigurations, have likewise become a thing of the past. This improvement significantly increases flexibility as well as efficiency in the production process.
