20-ESW IWS Extruder

Craft individually-wrapped process cheese slices quickly and reliably with the HART Design & Manufacturing servo-controlled 20-ESW IWS Extruder, with its cantilevered design for ease of operation and cleaning.

Take Your Slice on Slice Process Cheese Production to a Whole New Level with the Servo-Controlled HART 20-ESW IWS Extruder

The 20-ESW IWS Extruder Process

The HART IWS Extruder forms processed cheese into individual wrapped slices. Hot liquid cheese is pumped into a preformed continuous tube of film. The tube is then:

  • Flattened into a ribbon
  • Formed into slices
  • Crimped
  • Sealed with servo driven rotary heat bars
  • Cooled with chilled water
  • Cut to length

The individual slices are then stacked into a predetermined number of slices.
