Precise coordination: The automatic feeding machine assists in the weight sorting of salted egg yolks. Circular-shaped products can all be fed in this way.
In modern food processing, salted egg yolks, as the core raw material of traditional delicacies such as mooncakes and zongzi, the consistency of their weights directly affects the quality and cost control of the finished products. And the automatic feeding machine specifically designed for the weight sorting machine, through the close collaboration of its four modules, provides a reliable guarantee for the efficient and precise sorting of salted egg yolks.
First, salted egg yolks are key for mooncakes and zongzi. Their weight consistency matters greatly. In fact, it affects product quality and cost. Therefore, an automatic feeding machine helps sort them by weight. Moreover, this machine uses four cooperating modules.
To begin, the elevator starts the process. It lifts egg yolks from the hopper. Specifically, the elevator uses a bucket or belt structure. Then, operators can adjust the lifting speed. As a result, this controls the flow rate of materials.

Thus, the feeding avoids being too fast or too slow. Next, a diversion channel at the outlet arranges yolks in a single row. Consequently, this prepares them for the next stage.
Next, the vibrating feeder handles the yolks. However, the yolks often stick together due to their moist texture. For instance, the device uses high-frequency, low-amplitude vibration. In turn, this causes small jumps and displacements on the tray. Therefore, it effectively separates stuck individuals.
Moreover, the tray includes well-designed baffles. Specifically, these baffles guide the yolks to spread evenly. Thus, they form a single-layer arrangement. Consequently, this creates ideal conditions for precise feeding.

Next, the servo feeding system acts as the brain and muscle. Specifically, it receives instructions from the upper computer. Then, it drives the feeding belt or pusher via servo motors. In addition, the system feeds yolks one by one. Subsequently, it targets the pneumatic opening device.
Moreover, the servo system responds quickly and positions accurately. Meanwhile, it adjusts the feeding timing flexibly. In turn, this depends on the sorting rhythm. Thus, each yolk arrives on time at the predetermined spot. As a result, this avoids shortages or overstocking.
Finally, the pneumatic opening and closing mechanism takes over. Specifically, this mechanism includes quick-response pneumatic grippers or gates. When a yolk arrives, a cylinder opens the mechanism instantly. The yolk then falls into the container below. After feeding, the mechanism closes immediately.
Therefore, this prevents any excess material from falling. Meanwhile, sensors provide feedback for precise synchronization. In addition, the mechanism aligns with the high-speed running container. Thus, each operation achieves high accuracy: alignment, feeding, and reset.
Overall, these four steps work closely together. Then, they transform chaotic salted egg yolks into orderly single deliveries. Consequently, this automatic feeding system greatly improves sorting efficiency. Moreover, it also reduces damage and errors from manual handling. Therefore, it serves as a key link in modern intelligent sorting lines.
Through sensor feedback, the pneumatic opening and closing mechanism can achieve precise synchronization with the high-speed running container, achieving “alignment – feeding – reset” with high accuracy, precision and efficiency for each feeding operation.
From lifting, dispersion, feeding to loading, these four steps are closely interlinked, transforming the disordered and chaotic salted egg yolks into orderly and precise single deliveries. This automatic feeding system not only significantly improves the sorting efficiency, but also effectively reduces the damage and errors caused by manual intervention. It is an indispensable key link in the modern intelligent sorting line for salted egg yolks.
The weight sorting machine is an automated device installed on a production line that automatically weighs and sorts products by weight, or rejects defective products, during rapid product movement.
Simply put, it's like a combination of a highly accurate and fast-responding "smart scale" and a "sorter."
1,The weight sorting machine typically consists of 4 parts that work together to automatically weigh and sort products:
1.1,Conveying device: This device smoothly and evenly feeds products one by one into the weighing area via a conveyor belt or (tray), ensuring that only one product is weighed at a time.
1.2,Weighing device: This is the core component. As products pass through high-precision weighing sensors, the system quickly captures dynamic weight data and sorts them against preset standard values.
1.3,Sorting device: Based on the weight data and PLC judgment results, the actuator quickly moves to push, blow, or push away the graded products, while other products continue to the next process.
1.4,Control system: This is usually an industrial computer with a touchscreen, used to set parameters, display data in real time, calculate output, and store formulas for different products, facilitating production switching.

Q: When will you arrange the production for the weight sorting machine?
A: We usually arrange shipments immediately after receiving your payment if the weight sorting machine is in stock (about 2-3days). Otherwise, please confirm with us for the lead time (typically 15–30 working days).
Q: What is your accepted payment type for the weight sorting machine?
A: By TT, L/C. Usually, we would choose TT.
Q: Which logistics forwarders do you usually work with for shipping the weight sorting machine?
A: We usually compare the transportation time and price, and try to cooperate with the best transportation companies. You may also assign your own forwarder for shipment.
Q: What if the weight sorting is not sorting accurately?
A: 1. Check to ensure the product is within the rated weight range of the sorter.
2. Check to ensure the sorter is placed on a stable, vibration-free surface.
3. Check whether there are any foreign objects on the detection platform, or if there are any foreign objects on the weight sensor.
4. Check if the weighing platform has returned to zero, and view it on the touchscreen screen.
5. Check to ensure environmental factors (e.g., strong air flow, temperature fluctuations) are minimized.
6. Try recalibrating the sorting machine following the user manual instructions.
7. Restart the machine. If the problem persists, please contact our technical support for troubleshooting or warranty service.
Q: How does the weight sorting machine's sorting speed compare to manual weighing?
A: It depends on the model and product size, but a weight sorter typically sorts at a much faster rate (e.g., 60–360 pieces per minute) compared to manual weighing, with higher consistency.
Q: What is the sorting speed and accuracy of the weight sorting machine?
A: Sorting speed varies by model, ranging from 60 to 360 items per minute. Accuracy is typically within ±0.5g to ±2g, depending on the weight range and environment.
Q: What power supply should I use with the weight sorting machine?
A: Ensure the power supply matches the sorter’s rated voltage (e.g., 220V/50Hz) and provides sufficient current (typically 2A–10A). Using an incorrect power supply may damage the control unit. Or please provide your power voltage, and we will re-provide you with the electronic control system.
Q: Can I use a different conveyor belt instead of the one that comes with the weight sorting machine?
A: Yes, other compatible conveyor belts can be used, but to ensure optimal weighing accuracy and safety, we strongly recommend using the original belt specified by the manufacturer.
