Feather down production processDe-dusting:
Dust removing machines remove dust and dirt from feather and down. A rotating shaft in a cylinder agitates the material
while dust is discharged in special bags.Washing:
Washing takes place in big washing machines. It removes grease and dirt. The quantity of water needed for the washing
process depends on the type of washing machine and on the characteristics of the raw material, but normally 30 litres of
water are required for 1 kilogram of feathers. The most advanced washing machines can be electronically controlled: the
number of washing cycles, water temperature, rinsing times can vary in order to guarantee the best results. During the
washing phase, chemical agents are added to guarantee high hygiene and health standards. The rinsing phase can be
repeated three to five times. A large amount of water is needed to remove all possible residues.Centrifugation:
Elimination of exceeding water.Drying:
The material is dried and sanitised in order to meet the criteria of the law.Cooling:
This phase takes place in the cooling room.Sorting:
During this phase, down and feathers are separated by an adjustable airflow.Mixing:
Mix down and feathersas per different percentage & standard.
