Silo Dryers design examples

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.
 
Options

  • voltage and wattage variations
  • operating temperature variations
  • painting, multi-colour available as per customer request
  • labelling and documentation in various languages
  • electronic digital clock timer
  • operating hours counter
  • timer function, turns on after adjusted time (max 99h 59 min) (on request as well off)
  • high pressure blowers related to enforced heat capacity for enlarged air flow
  • easy-change fine air filter with difference pressure monitor and filter change monitor
  • base as per customer requirement
  • cut outs at cover for conveyors as per customer requirement
  • sockets for conveyors at terminal box
