The LED light inspection unit is installed beneath the 6-row rollers. As eggs pass over the rollers, the LED light illuminates them, allowing operators to visually identify and manually remove defective eggs, such as cracked, misshapen, dirty, or black-spotted eggs. The rollers are equipped with forced rotation bars that ensure continuous rolling of the eggs, providing a comprehensive view during inspection.
The egg candling device includes a candling hood and mirror, enabling operators to see the backside of the eggs, eliminating visual blind spots for a more thorough inspection. Additionally, curtains are installed at the front and rear of the candling hood, which can be drawn to create a darkened environment, enhancing the effectiveness of the LED inspection process.

The Visual AI detector features a non-contact design, allowing operators to scan eggs without direct handling, thereby significantly enhancing food safety and hygiene. This advanced system is equipped with self-learning capabilities, meaning it continually adapts to new standards and requirements by accumulating data and updating its algorithms. Leveraging big data technology, the system learns from a vast repository of historical data, which boosts the accuracy and efficiency of egg detection.
The inspection process utilizes near-infrared (NIR) light and image processing to automatically detect any defects. As the eggs rotate on the feeding rollers, a camera mounted at the top of the cabinet scans them. The NIR light strip beneath the rollers enhances image clarity, allowing the camera to capture detailed visuals that are then processed by the computer. Eggs with cracked shells, dirt spots, or any other non-compliant features are automatically identified and removed from the processing line, ensuring only high-quality eggs proceed further.

As eggs enter the grading process, they are sorted into 4 to 5 weight categories with a grading accuracy of ±1 gram. The grader is also equipped with a counting function, which records the number of eggs in each grade, as well as the total number processed per shift, per day, and overall production output.
The machine features a color PLC touchscreen, allowing operators to easily modify grading weights and other parameters directly on the screen for quick and convenient adjustments. Additionally, the grader is equipped with a unique intelligent self-diagnosis function that displays fault causes on the screen when issues arise, helping users quickly identify and resolve problems.
Furthermore, this grader is equipped with Wi-Fi capabilities, enabling remote monitoring and diagnostics via the internet. If a software issue occurs, it can be quickly addressed and resolved through remote access, minimizing downtime and ensuring continuous operation.

The Zenyer 401H egg printer with 1 print head can be mounted on the single-row egg graders and egg washers. The printer is activated by a photoelectric sensor as the eggs pass underneath, triggering the printing process.
This printer is capable of printing text, numbers, logos, and dates on the eggs, which enables traceability of the eggs' origin. This traceability reassures consumers by providing them with information that guarantees the quality and safety of the eggs.

The standard configuration of the 102BP egg grader includes three automatic egg packers, each auto packer comes along with an inclined angle tray loader and a loaded egg tray collection conveyor, and one manual collection table for manual collection as well. After grading, eggs are automatically sorted by weight and packaged into the corresponding lanes’ egg cartons and egg trays. This grader is compatible with 12-egg cartons and 30-egg trays, with each automatic packer dedicated to packaging a specific grade of eggs.

In addition to the eggs that are automatically packaged, other eggs fall into the manual collection lane. This manual collection lane can be divided into two sections if needed, allowing it to accommodate two different weight categories.
Eggs that are too large or too small are directed to the reject table at the rear of the machine, where they are separated for further handling.
