Rotary Drum Scaler
The Rotary Drum Scaler is Mikra’s efficient and continuous scaling solution for fish processing, designed to remove scales quickly and reliably without causing damage to the fish. The size and capacity of each unit is tailored to the specific installation, ensuring the right solution is in place for every facility and throughput requirement.
Effective scaling is a critical step in fish processing, where inconsistent or aggressive descaling can damage the product and reduce its value. The Rotary Drum Scaler addresses this directly with a simply structured yet highly effective rotating drum mechanism that removes scales efficiently and continuously, protecting product integrity throughout the process while keeping operation and maintenance as straightforward as possible.
Scales are collected in bins that are easily emptied, keeping the production area clean and minimising downtime between production cycles. The machine’s simple structure makes it easy to clean and maintain, supporting high standards of hygiene and reliable long-term performance.
What the Rotary Drum Scaler is used for
The Rotary Drum Scaler is used for the efficient and continuous removal of fish scales in land-based processing facilities, where reliable descaling without product damage is essential to maintaining raw material quality and supporting downstream processing steps.
The drum rotates clockwise for a specific time period while the fish is being scaled, then stops and rotates counter clockwise. A hatch then opens and the raw material exits the drum, while scales fall through holes in the drum and down onto a draining pan, where they are collected in bins for easy emptying. The doors are fitted with sensors that cut electricity to the motor when opened, ensuring safe operation throughout the process.
