American Kuhne Extruder Aids Blown Film
- August 06, 2012
ASHAWAY, RI | American Kuhne announces the Backdraft extruder, designed with a reverse air cooling system said to be ideal for blown film processing and other plastic processing applications.
Company says the design removes heat and air currents from the extrusion area for optimum bubble stability, while improving energy efficiency. Individual dampers for each zone provide what is called superior process control and operational simplicity. When the dampers are closed, they prevent the "chimney effect" present in most air-cooled machines that allows energy losses through convection cooling.
The dampers are connected to a common air plenum integrated into the machine base, which is connected to a single exhaust fan, either connected to the base or remote mounted. The single central exhaust blower removes the need for more traditional individual blowers on each zone. When a damper opens, air is drawn down through the heater's cooling fins and through the exhaust system. Reportedly, this reverse cooling arrangement eliminates the need for exhaust hoods, and eliminates any potentially damaging air currents near the bubble area.
