ENTEK has recently introduced a new vacuum stuffer/side feeder combination unit for use with its line of QC^3TM co-rotating twin-screw extruders.

The new QC^3TM Vacuum Stuffer/Side Feeder Combination Unit has been designed with numerous features that allow for easier operation and faster service than traditional vacuum stuffers and side feeders. Features and benefits include:

-Stuffer barrel can stay mounted to the extruder, while the rest of the unit is pulled out for cleaning. This means the barrel can be cleaned in place and the screws will be exposed for easier cleaning. (Quick Change + Quick Clean feature)

-Can be used as a vacuum stuffer or a side feeder, switching only cooling and vacuum hoses to change configuration.　 (Quick Change feature)

-Unit can be mounted to any of the 6 closest barrels to the arm mount (3 upstream & 3 downstream) (Quick Change feature)

-Bolts are designed to be easily removable with the built-in air ratchet.　All bolts intended for frequent assembly/disassembly are the same size; some are at an angle for easier assembly/disassembly (Quick Change feature)

-Mounted to top deck of extruder; preferable to separate unit with casters on the floor (typical side feeder), and easier access/service than mounting above extruder (typical vacuum stuffer)

-Arm is easily maneuverable

“We designed this new unit based on input from our customers, for better performance and easier serviceability,” said Linda Campbell, Director of Sales at ENTEK. “It further extends our QC^3TM concept of Quick-Change, Quick-Clean, and Quality Control for our twin-screw extruder line.”

ENTEK QC^3™ (Quick-Change, Quick-Clean, and Quality Control) co-rotating twin-screw extruders are available in 27MM, 43MM, and 53MM sizes. ENTEK builds co-rotating twin-screw extruders up to 133MM. The plan is to phase in the QC^3™ design changes to the entire machinery line in the future.
