Commissioning Time: Q3 2021
Vietnam is the world's largest pangasius exporter, with hundreds of seafood processing enterprises concentrated in the Mekong Delta. As a leading pangasius processor in the region, V****F exports products to Europe, America, Japan and the Middle East. With strict international requirements for product consistency and food safety, traditional manual slicing can no longer meet modern processing needs.
Core Challenges in Fish Slicing:
Capacity vs Orders: Over 30 tons of fish fillets need processing daily in peak season. Manual slicing requires hundreds of skilled workers but still fails to meet deadlines, causing order losses.
Thickness Inconsistency: Manual slicing error reaches ±2mm, affecting cooking uniformity. High-end customer rejection rate up to 10%.
Sanitation Risks: Seafood breeds bacteria easily. Frequent manual contact makes microbial control difficult, failing to meet EU import standards.
High Waste: Irregular slicing causes over 12% scraps, resulting in significant losses and reduced profits.
Hadof team customized a fully automatic fish fillet slicing line for V****F, tailored to the soft texture, high moisture and uneven fat distribution of pangasius:
1. Low-temperature Constant Temperature Feeding & Intelligent Shaping System
Circulating cooling system keeps fillet temperature at 0-4°C to maintain firmness and elasticity. Adaptive flattening rollers automatically adjust pressure to uniform fillet thickness for consistent slicing.
2. High-precision Fixed-thickness Slicing Unit
Food-grade corrosion-resistant stainless steel blades with servo-driven rotating discs. Thickness adjustable 3mm-20mm, error controlled within ±0.3mm. PLC dynamically matches blade speed and feeding speed for different fish textures, ensuring smooth, burr-free cuts and maximum integrity.
3. Online Visual Inspection & Automatic Sorting
High-speed vision camera system automatically inspects thickness, shape, and rejects irregular slices, scraps and fish bones. Qualified products are graded by weight/specification and directly connected to IQF tunnel or vacuum packaging machine for full automation.
4. Hygienic Design & Quick Cleaning
Full enclosed 304 stainless steel structure with rounded corners, no dead ends. Supports CIP cleaning and high-pressure water washing, reducing cleaning time by 70%. Quick-disassemble key parts meet top seafood processing standards (BRC, IFS, HACCP).
Since full operation in 2022, V****F has achieved qualitative leap:
Capacity & Efficiency
Daily capacity increased from <12 tons (manual) to 40 tons per shift, max 70 tons/day, becoming a benchmark for pangasius processing in Vietnam.
Labor Optimization: Slicing staff reduced from 120 to 10 technicians, cutting labor cost by 90% and eliminating reliance on skilled workers.
Quality & Market
Qualified Rate: 99%+ thickness consistency, scrap rate <2%, regular appearance. High-end customer rejection rate <0.5%.
Market Expansion: Passed BRC, IFS, MSC certifications, supplying European supermarkets (Tesco, Metro) and Japanese high-end catering. High-value fillet exports rose from 15% to 50% of total revenue.
Comprehensive Benefits
Raw Material Utilization: Increased from 86% to 96%, saving over $600,000 annually.
Energy Saving: High-efficiency variable frequency motors and intelligent standby reduce power consumption by 22%, awarded Green Manufacturing by Vietnam Ministry of Industry and Trade.
"Hadof's fish slicing line has transformed us from manual processing to intelligent manufacturing. Every pangasius slice reaches the global market with precise thickness and perfect appearance, greatly enhancing our brand value. It was the right strategic choice."
—— Mr. Nguyen Van Thanh, Production Director, V****F Seafood Corporation
