GroTech, a leading manufacturer of optical color sorting machines, offers advanced solutions for potato processing industries — including French fries and potato chips.
Our AI-powered sorters with high-definition camera recognition accurately detect and remove defects like browning, green spots, dark specks, and foreign materials. Designed for both wet and dry potato materials, GroTech sorters deliver up to 99.5% accuracy, improving yield, reducing waste, and ensuring every product looks perfectly golden and appetizing.

Why Choose GroTech for Potato Processing?

Tailored for demanding sorting tasks — built on optical intelligence and industrial reliability.✅ High-Definition Camera Recognition

GroTech employs industrial-grade HD CCD/CMOS cameras to capture fine surface details of potato strips and slices. The system detects browning, greening, dark spots, and peel residues with exceptional clarity, even during high-speed operation.

  AI-Based Intelligent Sorting

Advanced AI algorithms continuously learn from product data, distinguishing acceptable variations from true defects. This self-optimizing capability reduces false rejections and ensures long-term consistency and accuracy.

Fully Washable, Food-Safe Design

All product-contact parts are made of food-grade stainless steel and designed for quick, thorough cleaning. The structure prevents starch buildup and bacterial contamination, meeting international food safety standards.

Gentle Ejection & Handling

Precision air-jet systems and soft buffering ensure defective pieces are removed cleanly without damaging good products — ideal for delicate potato slices and strips.

Modular & Configurable Architecture

GroTech’s modular design allows flexible configurations: chute or belt type, multiple sorting channels, and optional infrared or RGB sensors. The system can be adapted to different capacities and product characteristics.

 Dual Application: French Fries & Potato Chips

French Fry Raw Material Sorting

GroTech sorters efficiently remove oxidized, green, or broken potato strips, ensuring even frying, bright golden color, and consistent product quality. By precisely separating defects early in the process, manufacturers can reduce waste and increase usable output.

Potato Chip Sorting

For potato chips, the sorter identifies burnt or discolored slices, uneven cuts, and foreign materials before frying or packaging. This prevents oil absorption caused by low-quality slices, reduces rework, and ensures a clean, uniform finished product.

In both wet (pre-freeze) and dry (pre-fry) environments, GroTech’s optical sorters maintain exceptional sorting accuracy — often exceeding 99.9%, while boosting throughput and yield compared with traditional manual sorting. Their robust construction and hygienic design make them ideal for continuous operation in food-grade production lines.

Global Reach & Industry Applications

GroTech’s product portfolio spans multi-functional color sorters, AI-driven optical sorters, and infrared sorting systems — serving industries such as grains, nuts, plastics, minerals, dried vegetables, and seafood.
With exports to more than 40 countries and regions — including the USA, Brazil, Vietnam, Russia, Nigeria, Bangladesh, and across Europe — GroTech continues to deliver reliable, intelligent sorting solutions to global partners.
