Scaling machine
Fish scaling Machine (Aquaculture / Processing)
Definition:
A fish scaling machine is a mechanical device designed to quickly and efficiently remove fish scales, typically before filleting or further processing. It is used in post-harvest fish processing units or in commercial aquaculture processing lines.
General operation:
-
Loading: fish are manually or automatically fed into the machine.
-
Descaling:
-
Rotating rollers, metal brushes, or abrasive discs spin at high speed.
-
The friction removes scales without significantly damaging the flesh.
-
-
Discharge:
-
Scales are removed via water or suction systems.
-
The descaled fish exits automatically for the next processing steps (gutting, filleting, etc.).
-
Common technical features:
-
Stainless steel construction to meet hygiene standards.
-
Adjustable speed to suit different fish species and sizes.
-
Capacity: from a few hundred to several thousand fish per hour.
-
Can be stand-alone or part of an automated processing line.
-
Easy to clean (HACCP compliance).
Advantages:
-
Significant time savings compared to manual descaling.
-
Consistent product quality.
-
Reduced physical strain for workers.
-
Adaptable to different species and sizes.
Disadvantages / Limitations:
-
High initial investment cost.
-
Less effective on species with very hard or irregular scales.
-
Risk of skin or flesh damage if poorly adjusted.
-
Requires regular maintenance.
