Fresh-Cut Pineapple Weighing Box Packing Line | 12 Head Belt Multihead Weigher
Automatic fresh-cut fruit weighing packing line with 12-head belt multihead weigher, 500g target, ±5g accuracy, 30BPM, gentle handling for pineapple, mango, salad produce.
This automatic fresh-cut fruit weighing and box packing system integrates a 12-head belt-type multihead combination weigher and box conveying line, custom-engineered for diced, sliced and chunked fresh pineapple. It delivers a target weight of 500g, stable weighing accuracy ±5g and consistent output at 30 boxes per minute.
Unlike traditional hopper multihead weighers with vertical drop impact, this belt-fed flexible weighing solution solves core pain points of juicy, soft pineapple flesh: bruising, browning, sticky residue and difficult sanitation. The line automatically completes material feeding, combinational weighing, precise gentle discharging and box conveying. It is widely adopted by fresh-cut fruit factories, salad processing plants and supermarket central kitchens for standardized clamshell/box packaging. Replace manual weighing and filling to lift throughput, cut labour cost and reduce giveaway loss. The system can be extended downstream with tray sealers, modified atmosphere packaging (MAP) machines, labelers and checkweighers for a full turnkey fresh produce packaging workflow.
Suitable Materials
Fresh-cut pineapple chunks, dices, slices
Fresh-cut mango, papaya, cantaloupe, watermelon, dragon fruit and other cut stone fruits
Prepped leafy salad, clean-cut vegetables and light-weight ready-to-eat produce
All fresh food requiring fixed-weight portioning into plastic trays, food boxes and clamshell containers
Final compatibility depends on moisture content, stickiness, piece size and box specification; on-site material test is recommended.
Key Industry Pain Points Solved
High giveaway & weight inconsistency from manual packing Manual portioning cannot stably hit 500g net weight. Overfilling wastes fruit, while underweight causes customer complaints and fines. Our line locks accuracy at ±5g, minimizing material giveaway.
Soft juicy pineapple gets crushed and bruised Conventional hopper weighers drop fruit vertically, causing flesh damage, juice leakage and rapid browning. Belt conveying delivers a smooth, low-fall transfer to preserve fruit integrity.
Sugary fruit sticks to hoppers, hard to sanitize Sugar-rich pineapple juice adheres easily to metal hoppers and breeds bacteria. Food-grade PU belts are quick-detachable and fully washable to meet food safety requirements.
Low manual throughput & rising labour shortage Manual weighing and filling limits order capacity for retail and pre-cut produce clients. Stable 30BPM continuous output reduces required packing operators sharply.
Spillage and uneven filling Servo box positioning synchronizes the conveyor with the weigher. Fruit lands evenly inside boxes, reducing spillage and delivering uniform retail presentation.
Product Features
12-Head Belt Multihead Weigher – Gentle weighing, no fruit bruising
Twelve independent belt weighing channels run intelligent combination algorithms to match target weight. Smooth belt transfer eliminates sharp drops and cuts damage rate. Frame is SUS304 stainless steel; food contact parts use juice-resistant PU belts, fully removable for washdown and sanitation.
Precision consistent weighing
Calibrated for 500g target weight with ±5g tolerance. Real-time weight sampling and automatic compensation ensure batch-to-batch weight consistency, avoiding short-weight claims and excess raw material waste.
Stable throughput 30 BPM
Continuous running speed of 30 boxes per minute, built for 24-hour fresh produce factory operation. Product parameters can be saved and recalled for fast changeover between different portion sizes.
Synchronized box conveyor with accurate positioning
Servo-driven tray positioning stops empty boxes exactly below the discharge point. Conveyor runs in signal sync with the multihead weigher for coordinated start/stop and fewer jams or mis-fills.
PLC + Touchscreen intelligent control
User-friendly HMI with recipe storage, production count, fault alarm and weighing data logging, supporting full production traceability for food factories.
Modular design, flexible expansion
Seamlessly add downstream units: tray sealer, MAP gas flush machine, labeler, checkweigher and rejection station to build a fully automatic fresh-cut fruit packaging line.
Working Flow
Feeding: Pre-cut pineapple chunks are delivered to each weighing belt lane of the 12-head weigher
Independent weighing: Each belt channel captures real-time weight of pineapple pieces
Intelligent combination calculation: Controller selects the optimal weight group to hit 500g within ±5g tolerance
Synchronized gentle discharge: Selected belts rotate together and release pineapple smoothly into the waiting box
Box conveyance: Filled boxes move downstream on the synchronized conveyor
Optional downstream packaging: Boxes proceed to sealing, gas flushing, labelling and weight inspection
