7-Head Flip Type Weigher (16L) — The Only Scale That Survives a Shift of Wet, Sticky, Fresh Product
Your product isn't dry granules. It's a whole fish that was swimming this morning, a tuna loin that bruises if you look at it wrong, a sausage that clings to every surface, or octopus tentacles that tangle into a knot the second they touch a vibrating plate. Now try feeding that into a standard rotary multihead weigher: the radial feeder wraps the product around its hub, the narrow buckets smear and bridge, the dead zones harbor bacteria your HACCP auditor will find in seconds, and by the third hour your line is stopped—again—for a manual clean-out that should have been a 10-minute rinse. You don't need a faster scale. You need a flip type multihead weigher built for the wet side of food processing.
Industry Pain Points
The fresh-processing paradox: why rotary weighers die on wet lines
Sticky product kills radial feeders. Whole fish, fillets, and marinated meat don't flow—they cling, smear, and wrap around the central cone of a rotary weigher. Within hours, the feed path is coated, portioning drifts, and operators are scraping product out with gloved hands between every batch.
Dead zones fail your audit. Rotary machines are full of seams, under-bucket cavities, and enclosed hubs where moisture and protein residue hide. No amount of surface wiping reaches them. When the inspector swabs those corners, your line shuts down—not for performance, but for hygiene.
Radial vibration bruises premium cuts. Sashimi-grade tuna and delicate white fish lose value the instant they're shaken. The high-frequency radial motion that moves dry snacks efficiently turns a $40/kg loin into downgraded trim in minutes.
Small buckets can't hold real seafood. A 2.5L hopper was designed for peanuts, not a 5kg sea bass. Force a whole fish into it and you bend the spine, burst the belly, and destroy the presentation your buyer pays for—or you simply can't run whole-fish SKUs at all.
The Solution
Meet the LEESOLU TY-ZHY07F 7-Head Flip Type Weigher (16L / Memory Hopper)—the only machine in our lineup engineered for the wet, sticky, fresh reality of seafood and meat processing.
Here's the architectural reversal: we abandoned the circle. Instead of a radial tower that fights gravity and traps residue, this is a linear weigher for sticky products—seven hoppers laid out in a straight, open row, each one a massive 16-liter memory hopper that holds a full portion (or a whole fish) without crowding. Product enters from a gentle low-drop conveyor, settles into the open bucket, and when the combination is solved, the entire hopper flips open like a clamshell—gravity does the rest, in one clean sweep, with zero smearing and zero residue left behind.
That flip motion is the heart of the machine. Because the bucket fully inverts, sticky fish skin, sausage casing, and marinade glaze release completely—no scraping, no buildup, no cross-contamination between batches. And because the whole frame is open, polished stainless steel with no enclosed hubs or hidden seams, your sanitation crew rinses it end-to-end in minutes, not hours. Audit-ready, every single shift.
We didn't tune this machine for speed. We tuned it so that a 5kg whole fish lands in the tray unbent, a sashimi portion arrives unbruised, and your night-shift cleaner goes home on time. For fresh processing, gentle and clean beats fast and clogged—every batch, every season.
Core Advantages
1. Flip-to-Clean Discharge: Zero Residue on the Stickiest Goods
Feature: Full-inversion clamshell hopper design; 7 independent linear buckets; polished stainless contact surfaces with no internal seams.
Advantage: When a hopper discharges, it rotates past vertical—gravity and geometry peel even the stickiest fish skin, sausage casing, and marinade glaze cleanly away. Nothing smears, nothing bridges, nothing hides.
Benefit: If you've ever asked how to weigh sticky products like fish and meat without sticking to hoppers, this is the engineering answer. No mid-shift scraping, no flavor carryover between SKUs, no protein film feeding bacteria. Batch integrity stays intact from the first fish to the thousandth.
2. 16L Memory Hopper: One Hopper Swallows a Whole Fish
Feature: 16-liter bucket volume per head—the largest in the LEESOLU catalog, over 6× a standard rotary hopper; wide-mouth rectangular geometry.
Advantage: A 5kg whole sea bass, a bulky salmon portion, or a tangle of squid fits in a single hopper without bending, squeezing, or overlapping. The "memory" function holds the portion steady until the exact combination fires.
Benefit: When buyers ask what size hopper do I need to weigh whole fish and bulky seafood, the answer is 16L—and it means you can finally run whole-fish and large-portion SKUs on an automated line instead of hand-packing your highest-value product. No spine-bending, no belly-bursting, no presentation loss.
3. Washdown-First Architecture: Audit-Ready in 10 Minutes
Feature: Fully open linear frame; no enclosed radial hub, no under-bucket cavities; IP-rated electrical components; all 304/316 stainless construction.
Advantage: Every surface is visible and reachable. A pressure rinse clears the entire product path end-to-end—no disassembly, no crawling into corners, no swab-fail surprises.
Benefit: For anyone searching where to buy washdown weigher for seafood processing lines in China, this machine is built around your sanitation SOP, not against it. Shift changeover cleaning drops from hours to minutes, HACCP/BRC auditors sign off on sight, and your line spends its time producing—not being scrubbed.
4. Gentle Linear Handling: Sashimi-Grade Product Stays Sashimi-Grade
Feature: Low-drop belt infeed; static settling in the memory hopper; soft gravity-flip release—zero radial vibration anywhere in the path.
Advantage: Delicate loins and fragile fillets are never shaken, tumbled, or abraded. They glide in, rest undisturbed, and drop once—gently—into the collection chute.
Benefit: To the question is a linear flip weigher gentle enough for sashimi grade fillets, the proof is in the tray: no bruising, no scale loss, no downgraded trim. You sell more A-grade portions per fish, and the premium your buyer pays for actually survives the weighing step.
Application Scenarios
Where "linear + flip + washdown" unlocks lines a rotary scale can't survive:
Whole Fish & Bulky Seafood Packing: Deployed as a 7 head flip type weigher for whole fish packing line and a 16L large hopper weigher for bulky whole fish and seafood cell. Sea bass, salmon, mackerel—each portioned or weighed whole at full size, unbent and unbruised, then dropped clean into trays or thermoform packs.
Sashimi, Loin & Premium Fillet Portioning: Running as a linear weigher for sashimi tuna salmon portion weighing station and a gentle handling weigher for fragile fish fillets without damage. Tuna, salmon, yellowtail, and white fish arrive in the retail pack exactly as the grader intended—no vibration marks, no value lost.
Tangled Cephalopods, Offal & Sticky Meat: Configured as a weighing machine for octopus squid and tangled seafood portions, a flip hopper weigher for sticky poultry meat and offal batching (tripe, hotpot ingredients), a linear combination weigher for sausage and meat chunk packing, and a flip type weigher for marinated meat and kimchi sticky portions module. Tentacles that knot, tripe that clings, sausages that smear, glazed marinades that coat—every one releases cleanly on the flip, with no bridging and no manual intervention.

FAQ
Q1: How much does a 7 head flip type weigher cost?
A: Pricing depends on stainless grade (304 vs 316), HMI configuration, and any custom infeed/conveyor integration for your existing fresh line. As a factory-direct builder, LEESOLU quotes transparently with no distributor markup. Send your product type, portion weight, and tray/pack format for an exact figure within 12 hours.
Q2: How to weigh sticky products like fish and meat without sticking to hoppers?
A: Two design answers: (1) the hopper fully inverts past vertical on discharge, so gravity peels even sticky skin and glaze clean away—nothing smears or bridges; (2) all contact surfaces are polished seamless stainless with no corners for residue to hide. The result is zero buildup and no mid-shift scraping.
Q3: Flip type weigher vs rotary multihead weigher—which is better for sticky food?
A: For dry, free-flowing goods, rotary wins on speed. For wet, sticky, fresh product, the flip type weigher vs rotary multihead weigher which is better for sticky food debate ends quickly: rotary radial feeders wrap and jam on sticky goods, and their enclosed hubs harbor bacteria you can't clean. The linear flip design releases cleanly, rinses end-to-end, and survives a full shift of fish or meat where a rotary would stop in hours.
Q4: What size hopper do I need to weigh whole fish and bulky seafood?
A: You need volume that holds the fish whole, without bending or squeezing it. Our 16L memory hopper accommodates a 5kg whole fish in a single bucket—roughly 6× the capacity of a standard rotary hopper. That's what makes automated whole-fish weighing possible instead of hand-packing your most valuable SKU.
Q5: Is a linear flip weigher gentle enough for sashimi-grade fillets?
A: Yes—it's the gentlest option we build. There is zero radial vibration anywhere in the path: product glides in on a low-drop belt, rests undisturbed in the memory hopper, and releases once via soft gravity flip. Sashimi-grade loins arrive unbruised, with no scale loss and no downgraded trim.
Q6: Where to buy a washdown weigher for seafood processing lines in China?
A: From a manufacturer that designs around your sanitation SOP, not against it. LEESOLU's flip type weigher uses an open linear frame, seamless stainless, and IP-rated electrics so your crew can pressure-rinse the entire product path in minutes—audit-ready every shift. Ask us for HACCP/BRC reference sites in your region.
Your Fresh Line Deserves a Scale That Gets Clean, Not One That Gets Clogged.
Every shift you run sticky product through a rotary weigher, you're paying for it three ways: stopped-line clean-outs, downgraded bruised product, and the audit risk hiding in corners you can't reach. Replace it with a machine that flips clean, holds a whole fish, and rinses end-to-end before your cleaner clocks out.
