Chaff Collection

Chaff Collection

While the Koffee Kosmo Roaster is agitating and roasting coffee beans 
  • During the first and second crack phase the bean husk as chaff  is shed off while roasting 
  • Once the husk separates from the beans, the chaff is forced to the outer chamber for clean, safe collection
  • Roasted beans in the roast chamber do not come contact again with the chaff during the roasting process
  • Approximately 98% of chaff is efficiently caught 

The roasting beans do not come into contact again during the roasting process once the husk separates from the bean

After the TO & roasted bean  insert is taken off

  • You can see how chaff is collected in the outer roasting chamber floor
  • We are left with 98% of collected chaff around the drive shaft as its final resting place
  • Once the roaster has cooled, the chaff is ready to be disposed of in the garden or bin
  • As seen - Great chaff separating results

 Clean roasted coffee beans are the result
