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
The catalogue lists ±0.3–2g weighing accuracy and 0.1g display increments. Display resolution is not measurement accuracy, and products close to a grade boundary may need an agreed decision rule. Test representative pieces around each boundary at the intended speed before accepting the grading setup.
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
The listed belt-speed adjustment range is 5–90m/min. Maximum speed and the best accuracy figure are not automatically simultaneous: product spacing, dimensions, vibration and settling time affect results. Agree the target throughput and validate weighing and outlet routing together with real products.
304 stainless steel body, built for the seafood floor
The listed 304 stainless-steel construction describes the material, not a confirmed washdown rating. Agree the enclosure protection and approved cleaning pressure, temperature, chemicals and method before installation. Do not infer high-pressure washing suitability from stainless steel alone.
100 presets + USB data export
The catalogue lists up to 100 presets and USB data export. Confirm the selected grading limits and run reference pieces after loading a preset. Before using an export for reconciliation or traceability, check the available fields, timestamps, batch identification and record completeness; a USB interface alone does not establish these functions.
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.
Weight thresholds make the grading rule explicit, but the listed ±0.3–2g accuracy and 0.1g display increment do not eliminate overlap near a grade boundary. Agree the grade limits and decision rule, then test pieces just above and below each limit at the intended speed.
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-steel housing can be evaluated for the proposed seafood process, but no complete-machine washdown rating is established by this catalogue entry. Confirm the cleaning procedure and the suitability of seals, electrical connections and pneumatic components for the actual salt, moisture and cleaning chemicals; routine washing must not be assumed harmless.
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.
USB export can support production record handling. Confirm whether the supplied software exports individual readings or grade totals, and verify batch identification, units, timestamps, missing-record handling and backup procedures against the intended workflow. Do not treat an unverified export as a complete traceability or settlement record.

Functions in Detail
Pneumatic grading action
The listed pneumatic supply is 0.5–0.8MPa with a Φ8mm air line. Before commissioning, confirm pressure under operating load, required flow, air preparation, connections and outlet timing. Pneumatic actuation alone does not establish moisture resistance or gentle handling; test routing and product damage with representative seafood.
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
USB export can support production record handling. Confirm whether the supplied software exports individual readings or grade totals, and verify batch identification, units, timestamps, missing-record handling and backup procedures against the intended workflow. Do not treat an unverified export as a complete traceability or settlement record.
Cleaning and corrosion resistance
The listed 304 stainless-steel construction describes the material, not a confirmed washdown rating. Agree the enclosure protection and approved cleaning pressure, temperature, chemicals and method before installation. Do not infer high-pressure washing suitability from stainless steel alone.
Gradable size and platform spec
The platform is 400×160mm, the listed maximum product size is 200×160mm, and the weighing range is 1–200g. The display increment is 0.1g; it is not an accuracy guarantee across that range. Confirm stable transport and measurement performance with the actual product dimensions, motion and operating speed.
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.
Buying stations can evaluate the 4–8 outlets for separating stock into agreed weight bands. The 0.1g display division is not proof of settlement accuracy. Confirm the grading method, reference checks and any applicable requirements before using results for commercial payment.
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.
