Development of Cracked Egg Detection Device Using Electric Discharge Phenomenon

Area of Science:

• Food Science and Technology
• Electrical Engineering
• Agricultural Engineering

Background:

• Eggs are nutritious but prone to cracks, risking bacterial contamination and economic loss.
• Traditional crack detection methods are insufficient for processed eggs due to altered physical properties.
• Existing technologies struggle with accuracy and reliability in egg crack detection.

Purpose of the Study:

• To develop a novel device for detecting egg cracks using electric discharge phenomena.
• To overcome the limitations of traditional egg crack detection methods, especially for processed eggs.
• To improve food safety and quality control in egg processing.

Main Methods:

• Designed a system applying a high-voltage electric field to eggs.
• Utilized flexible electrode pins and a rotation mechanism for 360-degree inspection.
• Employed numerical simulations to analyze electric field distribution and validate the method.

Main Results:

• Successfully detected cracks in both raw and processed eggs.
• Demonstrated efficient crack identification through spark generation at crack locations.
• Confirmed the method's validity via electric field and charge density simulations.

Conclusions:

• The electric discharge method offers a precise and reliable way to detect egg cracks.
• This technology surpasses existing detection methods, particularly for processed eggs.
• The system has potential for broader application in poultry product inspection and food safety.
