228A+ Automatic Medium & Large Fish Butterfly Fillet Cutting Machine

Executive Summary

The 228A+ Automatic Fish Butterfly Fillet Cutting Machine provides a continuous mechanical dissection solution engineered for high-yield aquatic processing. By substituting manual knife-work with a synchronous V-belt and rotary blade mechanism, this equipment mitigates structural damage to the flesh while maintaining precise dorsal and ventral cuts. Designed strictly around factory hygiene protocols and operational stability, it functions as a central unit for facilities handling variable fish dimensions while minimizing labor dependencies.

• Throughput Capacity: Processes 40 to 80 fish per minute, scaling output efficiency based on feeding speed and operator pacing.
• Dimensional Adaptability: Mechanically accommodates a wide raw material variance, processing fish weighing between 200 g and 4000 g with a maximum profile height of 16 cm.
• Optimized Footprint: Features a compact structural design (160 x 88 x 122 cm) combined with an energy-efficient 1.5 kW drive system, maximizing production per square meter.

Technical Specifications

Core Features & Advantages

• Dynamic Centering Mechanism (Maximized Yield): Employs a dual-track V-shaped conveyor system that mechanically centers raw materials before reaching the cutting zone. This physical alignment ensures the fish spine meets the rotary blades precisely, securing a uniform butterfly fillet and increasing flesh recovery rates over manual processing.
• Energy-Efficient Transmission (Reduced Overhead): Engineered with an optimized power-to-torque ratio, the entire mechanical continuous cutting process is driven by a 1.5 kW motor. This specific power setup lowers daily electrical utility loads while maintaining continuous blade rotation speeds for clean cuts without motor fatigue.
• Hygienic Washdown Architecture (Sanitation Compliance): Built entirely from SUS304 stainless steel with properly sealed electrical enclosures and sloped drainage surfaces. The 230 kg open-frame structure withstands high-pressure chemical washdowns, adhering to HACCP sanitary standards and accelerating daily shift cleaning procedures.
• Turnkey Scalability (Seamless Integration): The physical dimensions (160 x 88 x 122 cm) allow the unit to be retrofitted easily into existing factory floor plans. It connects fluidly with upstream descaling units and downstream automated skinners within complete fish & seafood processing machinery pipelines. For long-term preservation workflows, processed fillets can be immediately conveyed into downstream freezing systems for IQF processing.

Working Principle & Structural Design

The operational logic of the 228A+ is based on synchronized kinematics between the feeding track and the cutting head. Raw or chilled fish are manually or mechanically loaded belly-down onto the infeed chute. The machine's variable-speed synchronous belt grips the fish laterally, adapting automatically to any profile height up to 16 cm, and drives it forward into the enclosed cutting chamber.

Inside the cutting zone, high-speed rotary circular blades execute a continuous lateral incision. The blades are calibrated to slice along the skeletal structure, isolating the central spine while extracting an intact butterfly fillet. A targeted water manifold runs continuously during the operation, functioning to lubricate the blades, prevent thermal degradation of the protein, and simultaneously flush away bone fragments. Separated fillets exit via lateral discharge chutes, while the skeletal waste is ejected straight through the primary axis.

Industry Use Cases & Integrated Solutions

In mid-to-large scale processing environments, the broad weight tolerance of the 228A+ (200 g to 4000 g) proves highly practical for facilities handling multiple aquaculture species. During a continuous production run involving 1.5 kg chilled tilapia, operators can maintain a consistent feed rate of 60 fish per minute, allowing the facility to process over 5,000 kg of raw material per hour through a single machine.

Because the structural feed mechanism relies on dynamic tension, it micro-adjusts to slight variations in fish girth without requiring manual recalibration between batches. This capability ensures standardized fillet dimensions, which is a critical prerequisite when preparing seafood for downstream vacuum packaging or automated battering and breading lines.
