The High Precision Fish Weight Grading Machine for Seafood Processing Plants is a high-precision fish grading (weighing and sorting) device designed specifically for seafood processing plants. This device accurately weighs, automatically grades, and rapidly sorts fish (whole fish or fillets) of varying sizes and weights, significantly improving the efficiency and consistency of subsequent packaging, cold chain, and sales processes. For fish products (such as sea bass, salmon, cod, tilapia, and sea bream), weight and size consistency is directly linked to market value and customer satisfaction. This device serves as a key step in reducing human error and improving grading accuracy.
Grading and weighing are crucial components of the fish processing process. Excessive grading errors can lead to uneven packaging, customer complaints, high waste rates, and inconsistent product quality. لذلك, high-precision, سريع, and stable fish grading and weighing equipment is particularly important in modern seafood processing plants.
The operating principle of this grading machine can be summarized as a four-step automated process: "automatic feeding → precision weighing → grading control → diversion and discharge." The details are as follows:
Automatic feeding/conveying
Fish (or fish fillets) enter the weighing module from the front conveyor belt. A buffer belt, guide rails, or a fixed-distance feed mechanism typically ensures a stable entry into the weighing position.
Precision weighing module
High-precision load cells/load sensors (high-sensitivity sensing units) are used in the weighing area to measure the weight of each fish in real time. The system typically has multiple weight levels (grades), مثل 5, 8, or 10.
Grading determination/control logic
The weighing results are compared with preset grading thresholds by the control system (PLC, microcontroller, or industrial control module) to determine which grade the fish should be sent to.
Diversion/discharge mechanism
The system triggers a diversion mechanism (such as a flap, deflector, pneumatic actuator, or slide) to direct the fish to the appropriate discharge channel or container. في نفس الوقت, the conveyor belt pushes the next fish into the weighing area, forming a continuous assembly line operation.
Ultra-High-Precision Load Cell/Load Module
Using highly sensitive and anti-interference load cells, we achieve weighing accuracies of ±1g to ±5g or better (depending on the model).
Multi-Level Sorting Channel Design
Multiple weight levels (مثل 4, 6, 8, or even more than 10) can be set, with each fish automatically sorted and guided.
High-Speed Continuous Conveying + Diverter Mechanism
Equipped with a high-speed belt conveyor and automatic diverters (such as flaps, deflectors, and air thrusters), this system enables a continuous and stable sorting process.
Food-Grade Stainless Steel Construction + Waterproof and Rust-Proof Design
The machine body is constructed of food-safe stainless steel such as SUS304/SUS316, offering a smooth surface, no blind spots, waterproofness, corrosion resistance, and adaptability to humid environments.
Control System + Data Interconnection Capabilities
Equipped with a PLC/controller, a human-machine interface (touch screen), and data interfaces (such as USB, RS485, and Ethernet), it supports graded record keeping, traceability, and factory system integration.
High Efficiency / Large Processing Capacity
Automated continuous grading is faster than manual sorting and is suitable for high-volume fish production lines.
High Consistency / Low Error
Precision weighing + automatic judgment eliminates human error, ensuring consistent weight across each batch.
Reduces Labor Costs / Reduces Human Intervention
Reducing the need for manual judgment, weighing, and sorting, reducing human errors and management costs.
Clean and Hygienic / Compliant with Food Safety Standards
The all-stainless steel, easy-to-clean design with no blind spots facilitates daily cleaning and sterilization, and complies with HACCP, BRC, and FSMA requirements.
Improve product consistency and enhance market competitiveness.
Precise grading ensures consistent fish size, symmetrical packaging, and clear grades, enhancing customer trust and brand image.
Reduce defective rates, reduce errors, and reduce waste.
Automated sorting reduces mix-ups or mis-shipments due to manual errors, reducing losses and rework.
Shorten production processes and increase production capacity.
Automated grading reduces intermediate waiting time, making the entire process smoother and more efficient.
Data traceability and process transparency.
The equipment records data such as weight, grade, and time of each fish, facilitating quality tracking, production management, and customer feedback.
Overall, this High Precision Fish Weight Grading Machine for Seafood Processing Plants is an essential piece of equipment in the fish processing process for seafood processing plants, fishery processing companies, and cold chain exporters. By combining automatic feeding, precision weighing, intelligent flow diversion, and data management, it achieves high-speed, accurate, and consistent fish weight grading, providing a reliable foundation for subsequent packaging, freezing, shipping, and customer grading. Compared to traditional manual sorting methods, it offers significant advantages in efficiency, stability, cost control, and product consistency.
