3-Row High-Precision Electronic Egg Grading Machine
The NPW 3-Row Electronic Grader sets the standard for accuracy in mid-capacity packing lines. Combining individual egg weighing with optional acoustic crack detection, it ensures each egg is sorted not just by precise weight (±0.2g), but also by shell integrity. This dual-parameter control is essential for producing premium table eggs and ensuring the quality of eggs destined for further processing.

Eggs are singularized into three lanes, each equipped with its own precision weigh cell. A PLC records the weight in milliseconds and, if equipped, an acoustic sensor “taps” the egg to analyze the sound for hairline cracks. Based on the combined data, the egg is directed to the correct packing lane or a reject belt. This system provides unparalleled sorting intelligence.

In-Depth Advantage Analysis:
- Premium Product Creation: Allows for the creation of exact, consistent weight classes (e.g., Jumbo, XL, Large) that command trust and higher prices.
- Eliminates Hidden Defects: Acoustic detection finds hairline cracks missed by human candlers, preventing consumer complaints and spoilage in cartons.
- Total Process Control: Replaces the guesswork of manual sizing with digital precision, ensuring every package is perfectly compliant.
- Optimized Pack-Out: Maximizes the number of eggs that fall into your most valuable weight categories through precise boundary setting.
- Future-Proof Technology: The electronic platform allows for easy integration of additional sensors (e.g., color, dirt detection) in the future.
