Automatic Down-Discharge Fish Slicing Machine

High-Precision Automated Solution for Uniform Fish Fillet Cutting

Manual diagonal slicing of fish fillets relies heavily on operator experience. Workers must control cutting angle and slice thickness by hand, and even slight deviations can result in uneven sizes, broken edges, and raw material waste.
For delicate fish such as sea bass, yellow croaker, mandarin fish, manual cutting often causes meat cracking due to uneven force, significantly reducing final product yield.

The Automatic Bottom-Discharge Diagonal Fish Slicer Machine is designed to fully replace manual slicing, delivering millimeter-level precision, consistent thickness, and smooth cutting surfaces — ideal for industrial fish processing and export-oriented production.

Precision Diagonal Cutting with Smooth, Clean Edges

The machine uses a food-grade feeding board and automatic pushing system to keep fish fillets stable during processing, eliminating deformation caused by manual pressure.

Equipped with a dual-direction cutting system combined with reverse diagonal blades, the machine ensures:

• Clean, smooth cutting surfaces

• Uniform slice thickness

• Intact muscle fiber structure

• No tearing or squeezing of fish meat

This technology significantly improves product appearance and texture, making the fillets suitable for hot pot, ready-to-cook meals, frozen seafood, and high-end catering supply chains.

Adjustable Cutting Angle and Thickness for Different Applications

Different fish species and end-use products require different slicing specifications. This diagonal fish slicer supports full customization:

• Diagonal cutting angle: 15°–45° (customizable)

• Slice thickness options:

  • 2.5 mm

  • 3 mm

  • 6 mm

  • Other thicknesses available upon request

One machine can flexibly meet multiple market demands without frequent equipment changes.

High Capacity Output – Replace 15–20 Skilled Workers

Compared with manual slicing, the productivity advantage is substantial:

• Capacity:
  1,800–2,000 standard-size fish per hour

• Labor replacement:
  Equivalent to 15–20 experienced workers

The machine adopts a fully automatic feeding system. Operators only need to place deboned fish fillets into the inlet, and the machine automatically completes:

1. Positioning

2. Conveying

3. Diagonal slicing

4. Finished product discharge

This reduces labor dependency and stabilizes production efficiency, especially suitable for overseas markets with high labor costs.

Food-Grade Materials and Hygienic Design

The machine is manufactured according to strict food processing standards:

• Frame material: SUS304 stainless steel

• Blade material: Food-grade alloy steel with anti-rust surface treatment

• Corrosion resistance: Suitable for long-term wet seafood processing environments

An integrated PLC control system enables automatic water flushing and blade lubrication, preventing fish meat adhesion and ensuring continuous, clean operation.

FAQ – Buyer-Focused Questions

Q1: What type of raw material is required for this machine?

A: The machine is designed for deboned fish fillets. Whole fish should be pre-processed (de-scaling, gutting, filleting, deboning) before slicing.

Q2: Can the cutting angle and thickness be customized?

A: Yes. The diagonal cutting angle (15°–45°) and slice thickness (2.5 mm, 3 mm, 6 mm, etc.) can be customized according to your product requirements.

Q3: Does the machine damage delicate fish meat?

A: No. The dual-direction cutting and reverse diagonal blade design ensures smooth slicing without compressing or tearing the meat, even for soft-textured fish.

Q4: How many workers can this machine replace?

A: One machine can replace approximately 15–20 skilled workers, significantly reducing labor costs and improving output consistency.

Q5: Is the machine suitable for export markets and food safety regulations?

A: Yes. The machine uses SUS304 stainless steel and food-grade components, meeting common international food processing standards for export-oriented factories.

Q6: Can this machine be integrated into an existing fish processing line?

A: Yes. The machine supports standalone operation or integration with upstream filleting and downstream packaging or freezing lines.
