Fish Descaling Machine RL-FDM080

Pure high-pressure water jet descaling — there is no blade, no drum and no brush inside this machine. Only water. The fish lies flat on the mesh belt, fans of water strike both flanks at once, the scales fall through into the tray below, and the fish leaves the far end with its skin unbroken. 40–60 fish a minute, replacing a whole row of hand scalers.

Key advantages

Why water, instead of scraping

Water only — nothing solid touches the fish

No blade, no drum, no brush. The only thing that touches the fish is water, so the skin is not torn and the body is not bruised. Yield and appearance both survive.

Twin pumps, up to 90 bar, one pass

Two imported pumps of 5.5 kW each drive fans of water onto both flanks at the same time. No flipping, no second pass, no hand finishing afterwards.

40–60 fish per minute

Continuous output that scales with fish size. One machine does the work of a whole row of hand scalers.

Fully enclosed · doors open for washdown

A double-skin cabinet with double doors keeps scales and water inside the machine; open it up after the shift and hose the whole thing down.

PLC touch screen + VFD speed control

Belt speed adjusts to fish size and throughput from the panel. An operator picks it up in ten minutes.

SUS304 · castors and levelling feet

Every contact surface is food-grade 304 stainless. Castors let you move it; levelling feet hold it steady in place.

Part by part

What is inside, and what it is made of

Stainless mesh belt

The fish rides flat through the spray zone. Scales and water drop straight through the mesh into the tray below instead of building up on the belt.

Two independent pressure gauges

One gauge per pump, so working pressure is readable at a glance and anything abnormal shows up immediately.

Discharge chute with strip curtain

Descaled fish slide out on the chute; the curtain keeps the spray inside so the next station stays dry.

Inlet water filter

The water inlet is filtered to keep grit out of the nozzles and the pumps, which means fewer blocked nozzles and less downtime.

Infeed belt and PVC curtain

A blue PVC curtain seals the mist in at the infeed. The operator lays fish on outside the curtain, safe and dry.

Discharge end and waste hopper

A hopper under the machine collects scales and water in one place; hose it straight to the drain, no shovelling.

Operating limits of the fish descaling machine

Scaleless fish will not work

Pangasius, basa, catfish, eel and hairtail carry no scales for the jets to lift. Those species go straight to a filleting machine — descaling is a step they simply do not need.

Not for frozen fish

Once frozen, the scales lock into stiff skin and water will not shift them. Descaling is the first station on the line, so the fish must be fresh or fully thawed.

Not for very small fish

At sardine or anchovy size, 90 bar will damage the body. This machine is built for medium and large scaled fish.

Hand loading, not fully automatic

An operator lays the whole fish onto the infeed belt. The machine handles descaling and discharge; loading stays a manual step.

Before you order

The questions buyers actually ask

Q.Are you a manufacturer or a trading company?

RayLink is a fish-processing machinery exporter based in Qingdao, working closely with vetted manufacturers in the Zhucheng ("food-machinery capital of China") cluster. You get factory pricing plus one English-speaking person who owns the job end to end — selection, inspection, export documents and delivery.

Q.Will 90 bar of water damage the skin?

No. Pressure and nozzle angle are set to lift scales while leaving skin intact, the nozzles sit at a fixed distance, and the water spreads as a fan rather than a point jet. That is exactly the advantage of a water jet over a scraper blade — nothing solid ever touches the fish. Pressure is adjustable for species with firmer scales.

Q.Can it handle pangasius or catfish?

It cannot, and it does not need to. Those species carry no scales, so you skip descaling and feed them straight into a filleting machine. If pangasius or catfish is what you run, look at the RL-FFM filleting machine instead.

Q.Can I feed frozen fish directly?

No. Frozen scales lock into the skin and water will not remove them. The fish must be fresh or fully thawed — if your raw material arrives frozen, thawing has to come first.

Q.How much water does it use? Can it be recirculated?

About 50 L/min, with a filter on the inlet protecting the nozzles and pumps. Whether to add water recirculation depends on your plant drainage and supply — tell us the site conditions and we will work it out with you.

Q.Certification, warranty, payment and shipping terms?

The equipment is CE-marked and manufactured under an ISO 9001 quality system. Warranty is 12 months from the date of shipment covering the main structure and major components, wear parts excluded; common spares are in stock and best shipped in the same container. Payment is by T T or through an Alibaba Trade Assurance order. Shipping terms: FOB Qingdao / CIF / DDP.
