HWFT Series Intelligent Machine Vision Sorter A Single-layer Belt Model Custom

A single-layer belt model custom-developed for sorting fresh-cut French fries and pre-fried French fries. Adopting AI-powered high-resolution RGB visible light imaging technology, combined with continuous top-view and off-belt parabolic dual-mode inspection, it efficiently removes various defects that are hard to identify by traditional sorting equipment. Deep learning is applied to continuously optimize the precision of machine vision sorting.

During French fries processing, even minor color differences, surface blemishes or irregular shapes may compromise product consistency and damage brand reputation. Manual sorting alone is slow with volatile quality and high labor costs, failing to keep pace with high-speed production lines. Besides, French fries may flip and stack randomly on the belt. Traditional single-sided inspection tends to create blind zones, resulting in missed detection or false rejection.

The HWFT Series is an intelligent machine vision sorting system custom-designed to tackle the above challenges. Featuring a unique dual-mode inspection architecture (belt top-view inspection + off-belt parabolic inspection), it is equipped with high-resolution RGB (HR-RGB) visible light imaging technology, integrated with self-developed AI algorithms and high-performance pneumatic ejectors. It can effectively identify and reject discoloration, surface defects, shape abnormalities and foreign materials from French fries, greatly improving finished product consistency and providing solid assurance for food safety.

Its AI-powered surface defect recognition algorithm is trained via deep learning with real production data, enabling continuous improvement of sorting accuracy. With stable and reliable sorting performance, the algorithm helps French fry processors drastically reduce reliance on manual labor while upgrading product quality and processing efficiency.

• Machine vision sorting system customized for French fries
  • Dual-mode full-surface inspection architecture: Integrating belt top-view inspection and off-belt parabolic inspection. As French fries flip and stack randomly on the belt, off-belt parabolic inspection captures images of bottom and side surfaces. Synchronous scanning of dual modes maximizes full surface coverage.
  • Compact single-belt design: Quick-install structure with small footprint and flexible deployment.
  • High-performance waterproof vibratory feeding: Spreads French fries into uniform single layers to minimize overlapping and occlusion.
  • Easy-to-clean structural design: Food-grade stainless steel frame, sealed sorting chamber and electrical cabinet for convenient and efficient daily maintenance and cleaning.
  • Built-in humidity control system: Ensures stable equipment operation under complex working conditions and reduces downtime.
• AI-driven high-precision surface defect inspection system
  • High-resolution RGB (HR-RGB) visible light imaging: Captures fine surface details with high precision, effectively replacing manual sorting.
  • Self-developed AI algorithm: Enhances surface defect recognition. It supports model retraining based on real production data to continuously lift sorting accuracy through deep learning.
  • High-intensity LED lighting: Maintains constant imaging environment for clear and stable images.

High-precision machine vision detection for various French fry defects based on surface features:

• Color defects: browning, greening, dark spots, mildew
• Shape defects: breakage, malformation, out-of-spec size, residual potato skin
• Processing defects: scratches, indentations, uneven cuts, starch exudation
• Frying defects: burnt ends, oil stains, blistering
• Foreign material contamination: wood chips, packaging debris

• High-performance pneumatic ejector rejection system
  • Optimized design: Balances durability, response speed and air consumption efficiency.
  • Efficient and stable: Maintains reliable rejection and stable performance under high-throughput sorting.
  • Cost reduction: Greatly lowers false rejection rate and cuts overall operating costs.
