Segment Overview
The sorting and inspection segment serves as the “quality gatekeeper” of the egg processing line, responsible for accurately screening high-quality products from cleaned eggs. Utilizing advanced optical inspection and weight grading technologies, this segment ensures comprehensive quality control of both internal and external egg characteristics, guaranteeing that only compliant eggs proceed to subsequent processing stages.
Detailed Process Description
Optical Inspection Process
After cleaning and drying, eggs first enter the optical inspection area. Eggs move uniformly along the conveyor belt through a professional LED lighting system, allowing operators to clearly observe internal conditions through transmitted light. This process effectively identifies abnormal eggs including cracked eggs, dark-spotted eggs, scattered yolk eggs, and double-yolk eggs.
Weight Grading Process
Qualified eggs passing optical inspection proceed to the weight grading stage. Eggs are automatically queued and sorted via a new self-clearing egg conveyor before entering a high-precision weighing system. After precise weighing, each egg is automatically directed to different output channels based on preset weight classifications.
Graded Output Process
Following grading completion, eggs from each classification are transported to designated areas, preparing them for subsequent processes such as coding, oil spraying, and packaging. The entire workflow achieves full automation, minimizing manual intervention to the greatest extent.
