Belt-type high-pressure water fish descaling machine with adjustable water pressure. Processes 30–50 fish/min, preserves fish skin, and improves efficiency in processing plants and central kitchens.
In the fish processing industry, descaling is a critical step that directly affects the efficiency and quality of downstream operations. The belt-type high-pressure water fish descaling machine is a fully automated solution designed specifically for fish descaling, providing high efficiency, gentle processing, and reliable results. It is widely used in fish processing plants, central kitchens, and seafood markets, effectively solving problems such as low manual descaling efficiency, incomplete scale removal, and fish damage.
The machine is constructed from food-grade 304 stainless steel, including the frame, conveyor belt, water tank, and fish-contact components. This ensures:
Excellent corrosion resistance
Long service life under continuous exposure to water and fish
Prevention of metal contamination
Compliance with food safety and hygiene standards
The smooth, polished surfaces reduce scale residue, making cleaning and sanitation simple, while meeting strict hygiene requirements for food processing facilities.
The core structure includes:
Food-grade conveyor belt with anti-slip surface for stable fish transport
High-pressure pump assembly
Multi-angle spray nozzles
Variable frequency drive for conveyor speed adjustment
Fish are placed on the conveyor belt and automatically transported into the descaling chamber. High-pressure water jets spray from multiple angles, directly striking and separating the scales from the fish body.
The conveyor speed and water pressure are adjustable, allowing customization according to fish species, size, and scale hardness. Hard-scaled fish like carp and grass carp require higher pressure, while delicate species such as salmon and trout use lower pressure to avoid damage.
Operators only need to place fish on the conveyor belt

A: The machine is suitable for a wide range of freshwater and marine fish, including salmon, trout, grass carp, bream, whitefish, red fish, bass, tilapia, and more. Fish weight range: 100–3,000 g; width ≤12 cm; height ≤16 cm.
A: The belt-type high-pressure water descaling machine processes 30–50 fish per minute, depending on fish size and scale hardness.
A: No. The adjustable high-pressure water system ensures gentle, uniform descaling that preserves the integrity of fish skin and flesh.
A: Operators only need to place prepared fish (whole or partially processed) on the conveyor belt. The machine automatically feeds, sprays, and removes scales with minimal labor input.
A: Yes. Conveyor speed and high-pressure nozzle settings can be adjusted to match different fish species, sizes, and scale toughness. Higher pressure for hard scales, lower pressure for delicate fish.
A: Yes. Key components, including the conveyor belt and spray nozzles, are detachable for easy cleaning. Smooth stainless steel surfaces allow quick washing and sanitation. Routine maintenance is simple and ensures long-term stable operation.
A: The machine includes emergency stop buttons and a safe electrical design to protect operators. All water-contact components comply with food-grade hygiene standards.
A: Yes. The belt-type high-pressure water descaler can operate as a standalone unit or be integrated into upstream washing and downstream processing equipment.
