For situations where direct connection to the central rod conveyor from the chicken house is not feasible due to space constraints, it is recommended to use an automatic egg loader with dual-lifter head for automatic egg loading. You can manually place stacks of egg trays (up to 6 trays per stack) on the tray conveyor. The dual-lifter head will automatically pick up the eggs from the trays and transfer them to the accumulator of the egg grader. After alignment, the eggs are divided into two sets of 6 lanes, which then move into two 6-lane automatic egg turning devices.
Simultaneously, the empty trays will be automatically stacked at the end of the tray conveyor, allowing you to manually remove the neatly stacked trays. This system simplifies the egg loading process, ensuring efficient operation even in limited space conditions.

As the eggs pass through the specially designed turning mechanism, they are automatically oriented to ensure that the larger end, where the air cell is located, faces upwards after packaging. This orientation is crucial as it helps maintain the integrity of the air cell, which is essential for prolonging the eggs' shelf life.

After passing through the two 6-lane automatic turning devices, the eggs enter the two 6-lane LED light inspection units. Each LED inspection unit is installed beneath the rollers, ensuring comprehensive inspection as the eggs move along. The LED light illuminates the eggs, allowing operators to visually identify and manually remove defective eggs, such as those that are cracked, misshapen, dirty, or have black spots.

The rollers are equipped with forced rotation bars that keep the eggs continuously rolling during inspection, ensuring that all sides of the eggs are visible. The inspection units also feature a candling hood and mirrors, allowing operators to see the backside of the eggs and eliminate any visual blind spots. Additionally, curtains are installed at the front and rear of the candling hood, which can be drawn to create a dark room environment, enhancing the effectiveness of the LED inspection process.

As the eggs enter the grading process, they are sorted into 4 to 7 weight categories with a grading accuracy of ±1 gram. This process also includes a counting function, which records the number of eggs in each grade, the number processed per shift or day, and the total production output.
The grader is equipped with a color PLC touchscreen, allowing operators to easily adjust the grading weights and other parameters directly on the screen for quick and convenient modifications. It also features a unique intelligent self-diagnosis function that displays fault causes on the screen when issues arise, helping users quickly identify and resolve problems.
Additionally, the grader is equipped with Wi-Fi capabilities, enabling remote monitoring and diagnostics via the internet. In the event of software issues, they can be quickly addressed and resolved through remote access, minimizing downtime and ensuring continuous, efficient operation.

The Zenyer 401H egg printer with 1 print head can be mounted on the single-row egg graders and egg washers. It is activated by a photoelectric sensor as eggs pass underneath, triggering the printing process.
This printer is capable of printing text, numbers, logos, and dates onto the eggs, providing traceability for the eggs' origin. This traceability is crucial for ensuring consumer confidence, as it offers transparency about the quality and source of the eggs.

The standard configuration of the Zenyer 111 egg grader includes 8 automatic egg packers and 1 manual collection table. After grading, the eggs are automatically distributed to the appropriate auto packer according to the system settings. Users have the flexibility to increase or decrease the number of automatic egg packers based on their specific needs. The machine can automatically load eggs into various tray sizes, such as 2x5, 2x6, 3x5, 3x6, and 5x6, and users can choose between pulp, plastic, or foam trays based on their requirements. Each automatic packer is dedicated to packaging eggs of a specific grade.
Additionally, empty trays can be manually placed, or users can opt for an automatic de-stacking (automatic tray dispensing) device to further simplify the process.

In addition to the eggs that are automatically packaged, the remaining eggs fall onto the manual collection table. If needed, the manual collection table can be divided into three sections: one section for eggs that are too large or too small, and the other two sections for accommodating eggs from two different grades. This flexible setup allows for efficient manual handling and sorting of eggs that do not fit the automatic packaging criteria.
