Feather Meal Process Equipment / Feather Meal Extruder Machine

The Feather Meal Process Equipment is designed to efficiently convert wet feathers into high-quality feather meal, which can be used as a valuable protein source in animal feed. The process involves dehydration, extrusion, and pulverization to transform raw feathers into a digestible, sterilized, and nutrient-rich product. The equipment is engineered to cleave disulfide bonds and peptide hydrogen bonds in the keratin, making it easier for animals to digest and absorb.

Working Principle

1. Dehydration: Wet feathers are first transported into a dewatering machine for dehydration to reduce moisture content.
2. Cooling: After dehydration, the feathers naturally cool down to the required humidity.
3. Cutting: The cooled feathers are cut into smaller pieces.
4. Extrusion: The cut feathers are pushed through an extruder where the temperature and pressure gradually increase, causing the feathers to transition from a solid to a molten state.
5. Expansion: The molten feathers are ejected through the die hole, quickly cooling to normal temperature and pressure, causing them to puff and dehydrate.
6. Pulverization: After expansion, the puffed feathers are pulverized to create feather meal, which is more digestible and nutritious.

Nutritive Value of Feather Meal

• Crude Protein Content:
  • Hydrolyzed feather meal: 71%
  • Enzymatic feather powder: 82.6%
  • Expanded feather powder: 93.55%
• Amino Acids: Rich in cysteine, proline, arginine, isoleucine, and threonine, with some levels of lysine, methionine, histidine, and tryptophan.
• Minerals: Contains 0.45% to 2.02% calcium, 0.57% to 0.72% phosphorus, and 0.84 mg/kg selenium.
• Vitamins: Includes Vitamin B12 and growth factors beneficial for farming applications.
• Digestibility: The treated feather meal has a digestibility rate of over 90%, improving its feeding value.
