Why Choose MQ-CW5012L2-C6
Multi-grade sorting, 1-20 outlets
Choose from 1 to 20 sorting outlets. One machine grades fish, shrimp and lobster into a dozen weight classes, replacing an entire row of manual sorting stations. Selling by uniform weight grades lifts the price tier of your whole batch.
Dynamic accuracy from ±0.3g
Display resolution 0.1g, checkweighing accuracy ±0.3-2g (depending on product weight and belt speed), dynamic weighing across the 1-2000g range. For fresh-produce grading, even a few grams between grades is cut cleanly — no borderline products slipping into the wrong class.
5-90 m/min variable-frequency speed
Belt speed is steplessly adjustable from 5 to 90 m/min with a VFD-controlled motor. Run delicate peeled shrimp slower for accuracy, run uniform frozen bags faster for throughput — you set the speed-accuracy balance to match your order schedule, not the machine.
Waterproof build made for wet, cold plants
304 stainless steel housing with waterproof, moisture-proof construction. Daily washdowns, high humidity and low temperatures in seafood plants are business as usual. Hose it down at end of shift — no shielding and babying like an ordinary electronic scale.
100 recipes — no re-tuning at changeover
Store up to 100 product recipes on board. To switch products, just recall the recipe on the touchscreen and start the line — no re-entering parameters every time. In multi-product plants running hairtail today and prawns tomorrow, changeover time saved is output gained.
Five rejection types to match your product
Choose from air-blast, pusher, swing-arm, drop-flap and rotary rejection mechanisms. Air-blast handles soft fresh shrimp without bruising; pushers move full cartons of frozen goods steadily. The reject mechanism follows your product shape — your product never has to adapt to the machine.
Problems It Solves for You
Manual grading by feel means three workers produce three different standards for the same batch of lobster; mixed sizes get price-cut by customers or the whole shipment rejected
The machine sorts automatically by preset weight grades, with 1-20 outlets separating every class cleanly. ±0.3-2g accuracy keeps grading standards uniform across the line — graded goods finally command graded prices.
Peak-season labor is hard to find; a full row of workers on the sorting line drives costs up and still can't keep pace with shipping schedules
Multi-grade automatic weighing replaces manual sorting. With belt speeds up to 90 m/min, one machine does the work of a whole row of sorters — scale up in peak season without scrambling for labor.
High humidity, low temperatures and daily floor washdowns cause frequent moisture failures in ordinary equipment; every hour of downtime is an hour your fresh catch sits waiting
304 stainless steel housing with waterproof, moisture-proof construction, purpose-built for harsh high-humidity environments. Washdown cleaning is no problem, and moisture-related downtime drops.
Grading records kept by hand in ledgers — when a customer or inspector asks to trace the grading of a specific batch, you have nothing to show
Weighing data exports via USB, so grading records for every batch can be copied and archived anytime. Add the optional real-time printing function and shipping documents print on the spot.

Functions in Detail
Choosing the right rejection type
Five rejection mechanisms match different products: air-blast for light, delicate items like peeled shrimp; pusher for heavier boxed and bagged goods; swing-arm and drop-flap for continuous multi-grade sorting; rotary for round products or those needing smooth redirection. Tell us your product shape and weight before ordering and our engineer will spec the solution for you.
Data management and traceability
Weighing and grading data exports via USB for output statistics, batch traceability and reconciliation. Three-level operator permissions with custom passwords: operators run the machine, supervisors recall recipes, administrators change parameters — preventing accidental setting changes and keeping responsibilities clear.
Cleaning and daily maintenance
Full 304 stainless steel housing with waterproof construction — hose it down directly after shift in the seafood plant, no covers to remove. The weighing section measures 500mm×120mm, compact in structure, with an exposed belt that is easy to inspect and clear of debris. One operator handles daily maintenance.
Changeover and operation
Touchscreen HMI with intuitive parameter setup — new workers learn it in one on-the-job shift. With 100 product recipes stored on board, switching products means recalling a recipe and starting up, with no relearning or recalibration. Multi-SKU plants change over without losing output.
Installation and line integration
Power supply AC220V±10% — standard plant power works directly, no dedicated wiring needed. Handles products up to 350mm long and 120mm wide, connecting to the outfeed of upstream packing and sealing machines. Optional real-time printing, in-line inkjet coding, in-line labeling and code-reading sortation combine sorting and marking into one station.
Industries & Application Scenarios
Hairtail, yellow croaker and pomfret graded by piece weight. The 1-2000g range covers everything from small mixed fish to large-size fish, with graded outlets mapped to price tiers — no more hidden losses from selling big fish at small-fish prices.
Fresh and frozen shrimp graded by piece or bag weight, with air-blast rejection that never bruises the shrimp. Export-grade shrimp face strict count-per-kg specs; machine sorting keeps every carton's count consistent and inspection goes smoothly.
Crayfish and mud crab sorted into multiple price grades by piece weight. In peak season with heavy daily volumes, the 5-90 m/min belt keeps up with the buying rush — faster grading, faster dispatch, faster turnover.
Chicken legs, wings, ribs and other cuts graded by weight for tray packing. Products up to 350mm long can run on the line, and with drop-flap rejection, grading and weight verification are done in a single pass.
Bagged and boxed frozen goods checkweighed in-line after sealing. Underweight or out-of-tolerance packs are rejected automatically, stopping short-weight packages from reaching customers and triggering complaints and claims.
Side-dish packs and meal kits sorted by portion weight. 100 stored recipes handle frequent changeovers across many SKUs, and optional in-line labeling and inkjet coding print the weight straight onto the package.
