Why Choose MQ-CW412L2S-C4
Two lanes in parallel — one machine, two lines
Two independent weighing lanes sit side by side on a single frame, each with a 400×160mm weighing platform, feeding and grading at the same time without interfering with each other. When the peak shipping season hits, there's no need to buy a second machine or find a second footprint — one machine's cost and floor space delivers the output of two lines.
Grading accuracy from ±0.3g
Checkweighing accuracy of ±0.3-2g with a 0.1g display division. Crayfish are priced by size band, and adjacent grades often differ by only a few grams. At this accuracy level a 20-30g grade won't bleed into the 30-40g grade — even borderline shrimp land in the right bin. Clean grade separation is exactly what backs up your asking price.
4-8 way sorting, graded in a single pass
4 to 8 sorting outlets, expandable by N channels. Jumbo, large, medium, small and mixed grades each drop into their own bin in one weighing pass — no coarse pre-sort followed by a re-run. Halving the number of grading passes means one less tumble for each shrimp, so cracked claws and broken feelers drop too.
5-90 m/min, speed to match the catch
Belt speed is adjustable from 5 to 90 m/min: slow down for slippery, jumpy live crayfish to weigh steady, speed up for firm, uniform cooked tails to push volume. The same machine looks after weighing stability and can also run flat out when you're racing to fill a container — you never have to trade speed for accuracy.
304 stainless steel body, built for the seafood floor
The housing is full 304 stainless steel, standing up to daily high-pressure washdowns and the corrosion of brine and shrimp-shell juices without rusting or peeling. Hose it down at the end of the shift — cleaning is easy, food-contact hygiene is protected, and this is the dividing line between gear that survives three seasons and gear that doesn't.
100 presets + USB data export
Store up to 100 grading presets: switch variety or customer spec by calling up a preset — no stopping to reset. Weighing data exports via USB, so grade percentages and shift output are clear at a glance. Purchase settlement and customer reconciliation both have an original record — no more arguing over handwritten slips.
Problems It Solves for You
Hand-grading relies on the worker's feel — three people grade the same batch to three different standards. A few undersized shrimp slip into the 20-30g grade, and one failed spot-check at the customer means a price cut or a whole-batch return.
The machine grades by hard gram thresholds: ±0.3-2g accuracy and 0.1g resolution mean the bin each single shrimp falls into is decided by the number. The gap that lets grades bleed together is sealed at the source.
Crayfish is intensely seasonal — from May to August daily volume multiplies. Temp labor is hard to hire and wages double, the sorting table becomes the bottleneck of the whole line, and every extra day shrimp sit in the holding tank adds to losses.
The dual-lane build is effectively two grading lines on one frame, with belt speed up to 90 m/min. Machine grading isn't limited by working hours or shift rosters — at peak season it covers the workload of several sorters.
Seafood floors are cold and wet year-round, hosed down under high pressure every day. Ordinary equipment rusts and blisters within a season, and flaking paint chips carry a food-safety risk of getting into the product.
The 304 stainless housing is designed for seafood-floor conditions, paired with a pneumatic actuating structure. Daily washdown doesn't harm the machine, and it holds up for both service life and hygiene in a cold, salt-mist environment.
Buying and shipping run on eyeballed piles and rough bookkeeping — grade percentages and yield can't be pinned down. Month-end reconciliation with suppliers and downstream customers comes down to one handwritten slip, and when it can't be explained you just eat the loss.
Every single shrimp's weighing data is recorded; export it by USB and total it by grade. Grade percentages and batch output are in black and white, so settlement and reconciliation have original data behind them.

Functions in Detail
Pneumatic grading action
Grading is driven by compressed air: connect a 0.5-0.8MPa air supply and a Φ8mm standard air line and it's ready, matching the air-compressor setup common on seafood floors. A pneumatic structure resists damp better than purely electric actuators in a cold, wet environment; the action is crisp, shrimp drop from the matching outlet into the bin, and secondary knocks and claw loss are reduced.
Preset storage and changeover
The machine stores 100 presets, each holding one set of grading gram-band settings. Buying live crayfish at the morning market, grading tails in the afternoon, switching to river prawn out of season — just call up the matching preset to change over, with no need to re-enter parameters each time, cutting the whole-batch grading errors that come from mis-keyed settings.
Data export and settlement reconciliation
Weighing data exports by USB; after the shift, copy out the count and weight record for each grade. Purchase settlement, yield calculation and grade-percentage reports for customers all have supporting data. For exporters, this grading record is also original data you can produce for customer factory audits and batch traceability.
Cleaning and corrosion resistance
The housing is 304 stainless steel, standing up to daily high-pressure washdown, brine drips and the acidic corrosion of shrimp-shell juices. Hose the body down at the end of the shift — no worrying, as with powder-coated carbon steel, about rust spots and paint flakes contaminating the food-contact surface. It meets the hygiene requirements of a food-processing floor.
Gradable size and platform spec
The weighing platform measures 400×160mm; gradable product is up to 200mm long and 160mm wide, covering single whole shrimp, tails and even small boxed packs. The 1-200g checkweighing range with a 0.1g display division weighs accurately across the effective range, from peeled tail meat up to jumbo whole crayfish.
Industries & Application Scenarios
In the raw-material pre-treatment section of clear-water and braised crayfish lines, incoming mixed stock is graded by gram band — 20-30g, 30-40g, 40g-plus — and fed into different processes and price tiers. The 1-200g checkweighing range covers a single crayfish across every grade, from juvenile to jumbo.
At source-area buying stations, stock is graded and priced by size. Farmers' mixed loads pass over the scale once, the 4-8 sorting outlets drop them into bins by gram band, and pricing happens on the spot by grade. Both sides settle against a 0.1g division instead of arguing over hand-grabbed piles.
Frozen tails and whole crayfish are graded to the overseas customer's size spec before glazing, each gram band panned and quick-frozen separately, so a whole container isn't docked for mixed sizing. USB-exported grading data can be archived for customer factory-audit traceability.
Chain crayfish restaurants order by menu size spec; the central kitchen uses the two lanes to grade two categories or two order lines at once, portioning by gram band into boxes so every table's shrimp are uniform — cutting complaints at the store.
During shipping peaks, 'large' and 'medium' shrimp sell under different listing prices. Before dispatch each whole shrimp is weighed and graded into boxes, belt speed dialed low to weigh live shrimp steady — stamping out the bad reviews and platform refunds that come from passing small off as large.
Single-body seafood weighing 1-200g and no larger than 200×160mm — such as giant river prawn, crawfish or single shellfish — switches grading standards with a change of preset, so one machine covers several seasonal species.
