Mechanized Defeathering and Egg Sorting

Efficiency Unleashed: Poultry Processing, Simplified

Mechanized defeathering and egg sorting technology revolutionizes poultry processing by streamlining two critical aspects of the production process. These machines complete the feather removal process in just 30 seconds. Moreover, removed feathers are collected through an opening below the machine, ensuring cleanliness and hygiene in the processing area. In the egg sorting process, advanced sorting systems equipped with various sensors meticulously detect quality parameters such as weight, color, shape, and cracks. Operators can easily inspect eggs using a tubular lamp while handling the infeed and packing, ensuring that only eggs meeting specific quality standards are selected.


This technology is TAAT1 validated.

  • Inefficient Manual Processing: Time-consuming and inaccurate manual defeathering and egg sorting processes reduce overall efficiency.
  • Occupational Hazards and High Costs: Manual defeathering poses hazards, and egg sorting incurs high handling costs, impacting safety and financial efficiency.
  • Delayed Processing and Lower Profits: Delayed chicken processing reduces productivity, feed efficiency, and leads to rushed sales at lower prices, affecting profitability.
  • Inconsistent Grade Requirements: Manual methods struggle to consistently meet grade requirements for different poultry types and egg grades, impacting market acceptance.
  • Breakage and Losses: Manual egg sorting increases breakage risk, causing losses and affecting the overall quality of graded eggs.


  • Efficient Defeathering: Mechanized machines remove feathers in 30 seconds, enhancing productivity.
  • Automated Egg Sorting: Precision grading with sensors eliminates manual inaccuracies.
  • Timely Processing, High Quality: Quick defeathering maintains product quality, avoiding rushed sales.
  • Cost Reduction, Premium Pricing: Automated sorting reduces costs, attracting premium prices for eggs.
  • Versatile Poultry Handling: Machines efficiently handle various poultry types, reducing manual challenges.

Key points to design your business plan

This technology may be of interest to users (poultry farmers)

Incorporating mechanized defeathering and egg sorting technology in your business poultry processing, offering a solution to labor-intensive and inaccurate manual methods. It significantly speeds up the defeathering process and ensures accurate egg sorting, thereby improving productivity and product quality in poultry farms.

To integrate this technology,

  • The primary investment involves purchasing defeathering machines  250 to 500 depending on capacity and features.and egg sorting systems  which can range from USD 5,500 to 7000.,
  • Evaluate the quantity of equipment needed based on your production volume, and factor in costs for delivery, import clearance, and duties.
  • Collaborate with agricultural equipment suppliers or international resellers.
  • To match production volumes with machine capacities, there is a need for technically competent personnel. It is necessary to understand environmental regulations and establish waste management procedures for successful mechanical defeathering.

Consider complementing this technology with other technologies such as Value Addition and Storage Techniques to optimize overall farm efficiency and sustainability.

  1. Defeathering Process:

    • Slaughter chickens and drain blood.
    • Scald chickens in hot water (60°C for 2 minutes).
    • Place scalded chickens into the defeathering machine.
    • The machine, equipped with rotating metal discs and rubber fingers, completes the feather removal process in 30 seconds.
    • Defeathered chickens are then passed on for evisceration.
  2. Egg Sorting Process:

    • Collect eggs from various poultry types, including hen, quail, duck, and goose eggs.
    • Use an egg sorting machine equipped with weight-sensitive belts and sensors.
    • The machine detects quality parameters like weight, color, shape, and cracks.
    • Calibrate the belts to determine sorting criteria.
    • As eggs roll onto designated spaces, operators can visually inspect them with a tubular lamp for candling.
    • Sorted eggs are ready for packaging and transportation.
  3. General Requirements:

    • Ensure that the capacity of the equipment matches the flock size and production line specifications.
    • Have well-trained staff operate the machines.
    • Ensure an adequate supply of water and electricity.
    • Use specialty slaughtering equipment to minimize animal suffering and ensure meat safety.
    • Apply coating or move defeathered chickens to a filleting line for preservation.
    • For eggs, wash them using an odorless detergent solution with cool water and consider spraying with food-grade oil to reduce moisture loss and bacterial growth.
    • Regularly clean processing equipment made of stainless steel to maintain quality standards.
  4. Post-Processing:

    • For chicken, store the processed meat in a fridge or freezer for preservation.
    • Adhere to environmental regulations and establish waste management procedures for successful mechanical defeathering operations.
