The working process of the feather color sorter can be regarded as a perfect combination of optics, algorithms, and precision machinery. It performs a very delicate 'same color separation' task.
Below, I will provide you with a detailed analysis of how the feather color sorting machine performs sorting:
Core principle: Utilizing high-precision optical sensors to identify extremely subtle color differences, glossiness, and texture differences between feathers, and then separating different qualities or types of feathers through precise airflow.
The entire process can be divided into three core steps:
Step 1: Uniform feeding and imaging
Vibration dispersion: Mixed raw feathers are fed into a wide vibrating feeder. The purpose of the vibrator is to break up tightly wrapped feather clusters and evenly pass them through a specially designed downward channel in a single layer.
High speed photography: When feathers slide steadily in the channel, they will pass through a detection box. The box is equipped with a high-resolution, high-sensitivity full-color CCD camera and a specially designed light source system. The light source provides a stable, uniform, and shadow free illumination environment for feathers. At this moment, the camera will continuously "take pictures" of the falling feathers at a very high speed, capturing comprehensive information such as the color, luster, texture, and even shape of each feather.
Step 2: Intelligent recognition and decision-making
Image transmission and analysis: The high-speed image data captured by the camera is transmitted in real-time to the machine's "brain" - the central processing system.
AI algorithm recognition: The system is equipped with advanced intelligent recognition algorithms (usually AI models based on deep learning). This algorithm has "learned" tens of thousands of feather images of various qualities, and can accurately determine the category of each feather like an experienced master.
The sorting criteria include:
Color: Distinguish the yellow head, yellow edge, and stained feathers in white feathers, or distinguish feathers of different colors (such as white duck feathers and gray duck feathers).
Glossiness: Identify differences in gloss caused by improper washing, disinfection, or storage.
Texture and Form: Distinguish between Velvet, Feather, Damaged Hair, Irregular Hair, etc.
Millisecond level judgment: The system can analyze a feather within a few milliseconds and make a decision to "keep" or "remove" it.
Step 3: Precise Execution and Separation
Instruction issued: Once the system identifies the "target feather" that needs to be removed (such as a yellow head feather), it will immediately calculate the precise time when this feather falls to the nozzle.
High pressure airflow injection: At the moment when the target feather passes through the injection port, the system will command a high-frequency and high-speed solenoid valve to open, injecting an extremely short, precise, and strong stream of compressed air.
Trajectory separation: This airflow is like an "air knife", accurately blowing the flawed feather away from its original falling trajectory and into the "waste" or "defective" collection hopper. And high-quality feathers continue to fall along their original trajectory and enter the "good quality" collection bucket.
In summary, the workflow of the feather color sorter is a closed-loop "look think blow" process:
Uniform feeding → High speed photography → AI intelligent recognition → Precise airflow spraying → Perfect separation.
The advantages of this technology are revolutionary:
Extremely high precision: able to distinguish color differences and defects that are difficult for the human eye to detect.
Extremely efficient: One machine can process tens to hundreds of kilograms of feathers per hour, equivalent to replacing dozens of skilled workers.
Stable and reliable: unaffected by fatigue, emotions, and subjective judgments, ensuring consistent sorting standards.
Dataization: It can record sorting data, providing a basis for production management and quality control.
