Why Choose MQ-CW750TC6
6-20 sorting outlets, configured to your grades
Ships with 6 outlets as standard, expandable up to 20. Shrimp graded by piece weight or abalone by count-per-kg get sorted into the right grade in a single pass — no second run, no re-circulation. How many grades you need is decided by your pricing structure; the machine follows your grading standard, not the other way around.
Grading accuracy starting at ±0.3g
Display resolution of 0.1g with checkweighing accuracy of ±0.3-2g depending on the weight range. For small seafood in the 1-200g band, one gram on a shrimp is the difference between two size grades — this machine resolves that gram, so mixed-grade product never leaves your plant.
Tilting-tray discharge — gentle on premium seafood
Rejection is by tilting tray: each 145×70×50mm tray carries the product fully supported and tips to discharge at the target outlet. No pushers, no air jets, no gripping. Shrimp keep their antennae, sea cucumbers keep their skin, abalone keep their foot — with high-value seafood, appearance is money, and grading must not grade it away.
SUS304 body + IP65, built for seafood plants
Full stainless steel 304 housing, IP65 protection rating, food-grade trays. High salt, high humidity, crushed ice and brine, end-of-shift hose-down — all of it is within the design envelope. This is a machine engineered for wet seafood rooms, not a dry-room unit pressed into service.
100 recipes — change product, recall, run
Touch-screen HMI stores up to 100 product recipes. Grade shrimp in the morning and scallop meat in the afternoon: recall the recipe and start — no re-entering grade limits on the floor. The variable-frequency motor adjusts belt speed from 1-300 m/min to match your upstream and downstream line pace.
Tiered access + exportable data
Three operator permission levels with self-set passwords: line operators can only start and stop, so grade parameters can't be changed by mistake and ruin a batch. Sorting data exports via USB — output and share per grade in a clean table, for internal yield checks and for showing customers exactly what shipped.
Problems It Solves for You
Shrimp and abalone are sized by hand-feel; the morning shift grades differently from the night shift, batches ship with mixed sizes, and when an export customer's inspection catches it, the result is a price cut or a whole container rejected
Let the machine speak in grams: 0.1g display resolution and ±0.3-2g checkweighing accuracy. Once grade limits are set, every single piece is measured against the same ruler, and 6-20 outlets sort it in one pass — size consistency no longer depends on one experienced hand
Sea cucumber and abalone are priced by count-per-kg; every oversized piece slipped into a lower-grade pack is pure profit given away, and hand sorting can't see a few grams — nobody ever totals up what that giveaway costs over a year
Gram-by-gram grading across the 1-200g range: a small weight difference lands the piece in a different outlet, and oversized product goes back to the price tier where it belongs — with high-value seafood, one grade sharper means one grade higher on the invoice
Peak-season deliveries pile up, but hiring for an all-day standing job in a cold, wet grading room is hard and retention is worse — a whole row of sorters still can't keep up with incoming volume
Multi-grade automatic weighing replaces the manual sorting line. Belt speed adjusts from 1-300 m/min to match volume, the machine runs continuously without breaks, and people only load and collect — the sorting station shrinks from a full row to one or two workers
Brine corrosion plus a daily hose-down: ordinary equipment frames rust through in six months, water gets into the electricals and burns boards, and the downtime costs more than the machine did
Full stainless steel 304, IP65 waterproof rating, food-grade trays. Hose it down at end of shift without covering anything up — this machine is built to seafood-plant working conditions, not a dry-room design making do

Functions in Detail
Tilting-tray sorting: how it rejects and why nothing gets bruised
Each 145×70×50mm tray carries the product fully supported along the line; at the target outlet the tray tips and the whole load slides into the collection chute — no side pushers, no air blast. Shrimp antennae, sea cucumber spikes and abalone frills take zero impact. Choose 6-20 outlets to match your grade count, with room to expand later if your grading scheme grows.
Recipe and data management
The touch screen stores up to 100 product recipes: switch from shrimp to abalone or between sea cucumber sizes by recalling a recipe — no re-setting grade limits on the floor. Sorting data exports via USB, putting per-grade output and share into a spreadsheet for customer reconciliation and shop-floor yield accounting. Three permission levels with self-set passwords keep operators on start/stop only, leaving parameter changes to authorized staff.
Cleaning and daily maintenance
Full stainless steel 304 housing, IP65 protection, food-grade trays. Hose the machine down directly after the shift — brine, crushed ice and sea cucumber slime leave no hiding places. In a high-salt, high-humidity seafood room, the rusted-through-in-six-months problem of carbon steel frames simply doesn't exist here; daily care is rinse, dry, check the tray clips.
Speed adjustment and line matching
Variable-frequency motor with belt speed continuously adjustable from 1-300 m/min: slow down for light product and tight grade bands, speed up for large sizes and urgent volume. Whether infeed is manual tray-loading or automatic, and outfeed is a packing machine or crates, the speed dials in to your existing takt — no need to rebuild the line around one grader.
Power and installation requirements
Power supply is AC220V±10% — an ordinary workshop lighting circuit is enough, no three-phase power upgrade required. Site demands are minimal: position, connect power, level, load a recipe and test-run. Send us product samples and we run trial grading, tuning the grade limits until you're satisfied before the machine ships.
Industries & Application Scenarios
White shrimp and greasyback shrimp graded by piece weight: the 1-200g range covers everything from small counts to jumbo, sorting into 6+ grades in a single pass so export orders are packed grade-pure, never mixed.
Fresh and salt-cured sea cucumber graded by piece weight to set count-per-kg. With 0.1g display resolution you can see what every single piece weighs — when the count is right, pricing by grade stands up to any buyer.
Grading abalone by piece weight sets the count — and the price. Tilting-tray discharge tips the whole tray so nothing is pinched or knocked; live abalone pass through without shell damage or foot detachment, then go straight to the right holding tank or packing line.
Scallop meat and clams graded by net weight: small products within the L≤100mm, W≤65mm size envelope sit fully supported on the tray — replacing eyeball-and-scale sorting by hand.
Crayfish grading by the traditional qian (5g) bands sets the selling price directly. In peak season daily volume outruns any manual roster; the machine runs continuously and cleanly separates the 4-6 qian and 7-9 qian grades.
Gift-box seafood promises a per-piece size; if what ships doesn't match the product page, it's a bad review and a return. Grading by the gram makes every box uniform, and after-sales disputes drop visibly.
