Full-Automatic Crayfish Weighing and Cartoning System | Frozen Aquatic Product Integrated Packaging Line

Tailor-made end-to-end solution for crayfish and frozen seafood processing plants, delivering damage-free precision weighing, automated cartoning, quantitative sauce & oil filling, and seamless quick-freezing line connection

Industry Pain Points We Solve

• ·Fragile crayfish suffer extremely high breakage rate during traditional manual or rigid weighing, leading to low finished product yield, poor appearance quality and severe profit loss

• ·Manual weighing and cartoning cause large net content deviation, failing to meet strict import regulations of EU, US and other markets, resulting in product recall risks, customer complaints and loss of export qualification

• ·Dispersed weighing, cartoning and filling processes require heavy manual operation, leading to extremely low production efficiency, high labor costs and serious cross-contamination risks

• ·Non-waterproof equipment has high failure rate and short service life in high-humidity, high-corrosion aquatic processing workshops, and cannot withstand high-pressure flushing required for food hygiene

• ·Unstable sauce and oil filling causes dripping, carton contamination and poor sealing, leading to product spoilage, shortened shelf life and high scrap rate

• ·Lack of dedicated material recycling structure leads to serious raw material waste and uncontrollable production costs

• ·Poor compatibility with downstream quick-freezing lines causes uncoordinated production beats, long intermediate waiting time and damage to frozen product quality

• ·Equipment with sanitary dead corners is difficult to clean and sterilize, failing to meet HACCP, FDA, BRC and other global food safety standards

The whole line adopts full waterproof and sanitary design, realizing fully automated production from pretreated crayfish feeding to finished carton output for quick freezing, fully meeting the strictest global frozen seafood safety and export compliance requirements.

Core System Units

1. ·Inclined Conveyor: Equipped with food-grade chain plates and stainless steel ribs, realizing smooth, non-slip and drop-free conveying of crayfish. The open SUS304 structure is easy to clean and disinfect, with no sanitary dead corners.

2. ·14-Head 2.5L Multihead Weigher: All material contact parts are made of food-grade SUS304, with built-in food-grade silicone buffer pads exclusively designed for fragile crayfish, effectively avoiding shell breakage and product damage during weighing. It delivers ultra-high weighing accuracy of ±0.5g, ensuring strict net content consistency of each carton.

3. ·4-Head Automatic Box Feeding Machine: Realizes continuous automatic carton supply and positioning, perfectly matching the production beat of the upstream weighing unit and downstream filling stations, eliminating manual carton placement and greatly improving production efficiency.

4. ·Food-Grade Supporting Platform: Ergonomic anti-slip stainless steel platform compliant with food workshop standards, providing stable support for the multihead weigher and convenient access for equipment maintenance, raw material replenishment and daily cleaning.

5. ·Carton Conveying Line: Precise intermittent conveying system with dedicated carton positioning fixtures, ensuring accurate alignment of cartons with each filling station, avoiding material spillage and carton contamination.

6. ·Material Recycling Table: Dedicated recycling structure for scattered crayfish and raw materials, realizing efficient collection and reuse of raw materials, minimizing production waste and maximizing raw material utilization.

7. ·4-Outlet Pneumatic Oil Filling Machine: High-precision quantitative oil filling unit with anti-drip nozzles, exclusively optimized for edible oil and seasoning oil filling for crayfish products. The 4-outlet design matches multi-station production, achieving no-cartoon-no-filling and zero dripping contamination.

8. ·400L Oil Storage Tank with Operating Platform: Large-capacity food-grade SUS304 storage tank, providing stable and continuous oil supply for the filling unit. The matched operating platform ensures convenient oil replenishment, equipment maintenance and daily cleaning.

9. ·Sauce Filling Machine: High-precision filling unit optimized for high-viscosity crayfish seasoning sauce, with anti-blocking and anti-drip structure, realizing stable and accurate quantitative filling, and fully adapting to various sauce formulas.

10. ·Quick Freezing Cases Transition Conveyor: Seamlessly connects the packaging line with the downstream quick-freezing line, realizing smooth and continuous conveying of finished cartons to the quick-freezing process, avoiding intermediate waiting time and ensuring the quality of frozen crayfish products.

Standard Automated Workflow

1. ·Smooth Material Conveying: Pre-treated crayfish are fed into the inclined conveyor, which transports the crayfish smoothly and stably to the feeding hopper of the 14-head multihead weigher, with stainless steel ribs preventing material dropping.

2. ·Damage-Free Precision Weighing: The 14-head multihead weigher completes high-precision quantitative weighing of crayfish according to the preset target weight, with food-grade silicone buffers minimizing crayfish breakage during the whole process.

3. ·Automatic Carton Feeding & Positioning: The 4-head box feeding machine automatically supplies empty cartons and positions them accurately under the discharge port of the multihead weigher, synchronizing with the weighing beat.

4. ·Automatic Cartoning: Weighed crayfish are accurately dropped into the positioned empty cartons, completing the automatic cartoning process.

5. ·Quantitative Sauce & Oil Filling: Cartons with crayfish are conveyed to the sauce filling machine first for precise quantitative sauce filling, then to the 4-outlet pneumatic oil filling machine for oil perfusion, with anti-drip nozzles avoiding carton contamination.

6. ·Material Recycling & Finished Product Conveying: Filled cartons are transported via the main conveyor line, and scattered raw materials are collected and reused through the dedicated material recycling table.

7. ·Quick-Freezing Line Connection: Finished cartons are smoothly transferred to the downstream quick-freezing line through the quick freezing cases transition conveyor, completing the full automated production cycle.
