Dual-lane live fish sorting system

Full-Automatic Dual-Lane Live Fish Sorting System | Waterproof Weight Grading Line for Tilapia, Tuna & Commercial Aquaculture

Industry Pain Points We Solve

• ·Manual live fish sorting has extremely low efficiency, large grading error and inconsistent specifications, leading to reduced product premium, severe profit loss and frequent customer complaints

• ·Manual handling causes high stress, physical damage and mortality of live fish, especially for high-value tilapia and tuna, resulting in huge raw material loss and increased production costs

• ·Single-lane sorting equipment has an obvious capacity bottleneck, unable to meet the demands of large-scale continuous aquatic processing

• ·Traditional sorting equipment has poor waterproof performance, high failure rate and short service life in high-humidity, high-corrosion aquatic processing workshops

• ·Equipment with sanitary dead corners is difficult to clean and disinfect, failing to meet strict global aquatic food safety regulations (HACCP, FDA, EU 10/2011)

• ·Unreasonable flow channel design causes common problems such as fish jamming, pinching and cross-channel mixing, leading to secondary damage, sorting failure and increased mortality

• ·Limited grading grades cannot meet the needs of multi-specification refined sorting, restricting product pricing power and market competitiveness

• ·Separate single-lane lines occupy excessive workshop space, with high equipment investment and operation costs

• ·Height and direction adjustable collection device with quick-disassembly structure, saving workshop space and facilitating fish collection and cleaning

Our Tailored Integrated Solution

We provide a fully automatic, dual-lane live fish weight sorting system exclusively designed for commercial aquaculture and aquatic processing plants. This integrated solution seamlessly combines dual-lane high-precision check weighing, 6-grade intelligent sorting, food-grade conveying and independent dual control systems, perfectly solving all core pain points of live fish grading. The whole line is built with food-grade waterproof design, realizing fully automated, damage-free and high-efficiency sorting from manual feeding to graded collection, fully meeting the refined processing needs of tilapia, tuna and other commercial fish species.

Core System Units

1. ·Dual-Lane 6-Grade Intelligent Sorting Machine

   Equipped with independent control systems for Lane A and Lane B, supporting flexible setting of 6 weight grading thresholds for each lane according to production requirements. The optimized sorting mechanism ensures accurate and gentle diversion of live fish to the corresponding grade collection device, with no damage to fish bodies during the whole process.
2. ·Food-Grade Live Fish Conveying System

   The whole line main body is made of food-grade SUS 304 stainless steel, with 50-60mm diameter round tube legs and open square tube frame for easy flushing and cleaning. The live fish contact conveying part adopts food-grade belt or plastic anti-slip mesh belt structure, ensuring smooth and stable transportation of live fish with no slipping or damage.
3. ·Adjustable Graded Collection Device

   Height, left and right adjustable collection devices are installed under both Lane A and Lane B, supporting collection of live fish from Lane A towards Lane B direction. The quick-disassembly and quick-fix structure greatly facilitates fish collection, equipment cleaning and workshop layout optimization.
4. ·Waterproof Electrical Control System

   All electrical components adopt waterproof design or waterproof structure protection, with a dedicated dehumidifier installed in the electrical control box. The independent dual-lane control system supports separate operation of each lane, ensuring continuous production even during single-lane maintenance, with an intuitive touch screen for easy parameter setting and operation.
5. ·Anti-Jamming & Anti-Cross Channel Feeding Structure

   Each lane is designed with an adjustable fish guide plate, with a 150mm raised lever to prevent cross-channel mixing. The optimized flow channel design completely avoids undesirable phenomena such as fish pinching and jamming, ensuring smooth and damage-free transportation of live fish.

Standard Automated Workflow

1. ·Smooth Feeding: Live fish are manually introduced into the dual-lane feeding end, and smoothly transported to the rear end through the food-grade anti-slip conveying system. The adjustable fish guide plate ensures single fish orderly feeding, with a 150mm raised lever to prevent cross-channel mixing.

2. ·Dual-Lane Precision Weighing: Live fish are transported to the dual-lane check weigher, where each lane completes independent, real-time and high-precision weight detection, and transmits the weight data to the control system synchronously.

3. ·Intelligent Grade Sorting: The control system matches the detected weight with the preset grading thresholds, and sends a signal to the dual-lane 6-grade sorting machine, which accurately diverts the live fish to the corresponding grade collection device gently and without damage.

4. ·Graded Collection: Live fish of each grade fall into the corresponding adjustable collection device, which can be flexibly adjusted in height and left-right position, with a quick-disassembly structure for convenient fish collection and cleaning.

5. ·Continuous Stable Operation: The whole line runs continuously, with independent dual-lane control system supporting flexible single-lane or dual-lane operation, fully adapting to different production capacity demands.
