What’s in the Pipeline of New Compounding Machinery Developments at Farrel Pomini
Compounding biopolymers, automatic movement of rotor to seal line, adjustable mixing dam, a twin-screw pump for special applications and more.
I reported recently on my visit to the brand-new headquarters of Farrel Pomini in Ansonia, Conn., for the grand opening of the facility in April. The grand opening event included presentations summarizing the latest technical developments in Continuous Mixers and Compact Processors:
• As reported previously, the company is actively investigating new opportunities in compounding biopolymers such as PLA. Farrel Pomini equipment is seen as appropriate because of its “gentle” treatment such sensitive polymers, with low shear and short residence times.
• The new Farrel Pomini Synergy System, a common framework with common standards for integrating the company’s compounders with third-party equipment and controls in a processing line.
• All systems now have a VPN gateway for remote web-based support in real time. This system can enable Farrel Pomini engineers to adjust machine operating parameters and control limits “on the fly” while a line is running.
• The newly patented Self-Aligning Seal (SAS) for the feed end of a Continuous Mixer, which was introduced at NPE2015 and is now used on every new machine (and also retrofittable), has been supplemented with a Self-Aligning Viscoseal (SAVS) for the discharge end of the mixer (see image). Like the SAS, the SAVS automatically moves with the rotor to compensate for thermal expansion, rotor wear, and deflection of the rotor by the process material. The SAVS utilizes a melt film for sealing and incorporates a reverse screw thread to retain the melt and prevent leakage. The patent-pending SAVS is still in testing at the Ansonia lab and will enter field testing soon.
