3. Duck feather processing techniques

1. Washing and disinfection are used to remove dust, sand, skin flakes and musty odors from the down. In China, detergents are often used to assist washing, and after washing, some white oil (white machine oil) is added to increase luster and prevent insect damage.

2. Dehydration mainly uses a centrifuge. Generally, dehydration is carried out in a centrifuge for 5 minutes at a speed of 600 rpm.

3. Drying mainly uses the high-temperature steam disinfection of a dryer. That is, using a high temperature of 120~130°C to both dry the down and sterilize it. Note that drying is a highly technical process. Workers who master feather drying must be highly focused, not only paying attention to the operating time of each drying cycle, but also paying attention to the fluffiness of the feathers and constantly judging the right moment.

4. Cooling can further remove the peculiar smell of the down through the exhaust screen of the cooling machine, which helps further improve the quality of the duck down and also helps restore the natural moisture content of the feathers and down. If the moisture content in duck down exceeds the natural moisture level, the duck down is prone to mildew and spoilage; if the moisture content is lower than the natural moisture level, the duck down will become brittle and break easily, affecting quality.

5. Packaging and storage: for dried duck down, attention should be paid to extending the spreading and cooling time to ensure that the duck down can fully recover its natural moisture. In addition, packaging should not be too tight. Because duck down is a product with good insulation, if packaged too tightly, it is not only difficult to dissipate heat, but also easy to produce water vapor and difficult to store; it may also deform the duck down and affect its elasticity. Therefore, duck down packaging should preferably be controlled at around several tens of kg per package. After washing and disinfection, duck down is generally required to be stored for more than 30 days before it can be used to fill duck down products.
