Industrial Oven Systems and Pre-Heat devices

Silo Dryers standard designs

APPLICATION

Warm-air-dryers are used for drying and pre-heating solvent-free synthetic granulates. Advantages here are:

  • enlarged plasticizing capacity
  • quality improvement
  • quality assurance
  • improved flow behaviour


Surface humidity at granulate will be achieved with non-hygroscopic synthetics (e.g. PE, PP,PS, etc.) with unfavourable storage, large temperature differences and condensate with high air humidity.  A pre-heating is necessary to remove condense humidity. Several machinery can be served by one dryer.
