High-pressure water hairtail fish descaling machine for industrial seafood processing. Capacity 40–80 fish/min, descaling rate over 98%, minimal skin damage. Fully automatic, food-grade stainless steel, ideal for large fish processing factories.
In the modern seafood processing industry, hairtail fish (belt fish) descaling has long been considered one of the most labor-intensive and quality-sensitive preprocessing steps. Traditional manual descaling is slow, inconsistent, and highly dependent on worker skill. Mechanical scraping methods often lead to skin damage, flesh loss, and reduced product value.
The High-Pressure Hairtail Fish Descaling Machine is specifically engineered to address these challenges. By utilizing advanced high-pressure water jet technology, this machine delivers fast, precise, and non-contact scale removal, ensuring high throughput, minimal fish damage, and consistent processing quality. It is an ideal solution for industrial seafood processing plants, hairtail export factories, and large-scale fish preprocessing lines.
Hairtail fish are widely consumed and traded due to their tender flesh, high nutritional value, and strong market demand. However, their fine white scales, although loosely attached, present several processing challenges:
Manual descaling is time-consuming and labor-intensive
Inconsistent scale removal affects downstream processing and appearance
Mechanical descaling methods can scratch skin and damage flesh
High labor dependency increases operating costs and limits scalability
Difficulty maintaining uniform quality in large-scale production
As processing volumes increase and labor costs rise globally, seafood processors are under pressure to adopt automated, high-efficiency, and low-damage solutions. High-pressure water descaling technology has emerged as a breakthrough approach for hairtail processing.
The High-Pressure Hairtail Fish Descaling Machine operates on a fundamentally different principle from traditional mechanical descalers.
High-pressure water pump pressurizes clean water to a controlled intensity
Water is released through precision-engineered nozzles
High-speed water jets directly impact the fish surface
White scales detach instantly under hydraulic force
Scales are flushed away without friction or abrasion
Because hairtail scales are not tightly bonded to the skin, the water jet force selectively removes scales without affecting fish skin or flesh.
Non-contact descaling eliminates mechanical damage
Uniform scale removal across head, body, and tail
Adjustable pressure for different processing requirements
Continuous operation suitable for industrial workflows
This technology ensures high descaling efficiency while preserving product integrity, a critical factor for premium seafood markets.
Efficiency is a core requirement for large seafood processing operations. This machine is designed to meet high-volume production demands.
40–80 fish per minute
Up to 2,000 hairtail fish per hour
Continuous operation for long production shifts
Compared to manual processing, a single machine can replace multiple workers, delivering consistent output without fatigue or quality fluctuation.
Significant reduction in processing time
Higher daily throughput
Improved line balance in integrated processing systems
Faster order fulfillment for export and wholesale markets
For factories processing hairtail fish at scale, this translates directly into higher productivity and stronger market competitiveness.
≥ 98% scale removal efficiency
No residual scales on head, body, or tail
Uniform surface finish improves visual quality
Unlike scraping or brushing systems, the high-pressure water method:
Does not scratch fish skin
Does not tear flesh fibers
Maintains natural appearance and texture
Preserves nutritional value
This is especially important for processors supplying fresh, frozen, or export-grade hairtail products, where appearance and yield directly affect selling price.
The machine is equipped with an intuitive control system:
Simple pressure adjustment interface
One-button start and stop
Minimal operator training required
Workers only need to place hairtail fish on the conveyor and set the appropriate pressure level. The system handles descaling automatically and consistently.
High-quality water pump and components
Precision-manufactured nozzles
Robust stainless-steel frame
Designed for long-term continuous operation
This stability reduces downtime, maintenance frequency, and overall operational risk.
Food safety and hygiene are non-negotiable in seafood processing.
304 food-grade stainless steel
Corrosion-resistant and durable
Suitable for wet processing environments
Smooth surfaces for easy cleaning
Efficient water flushing of scales
Reduced accumulation of residue
Compliant with seafood processing hygiene standards
The machine is well suited for facilities operating under HACCP, GMP, or export certification requirements.
