Potato Grading and Cleaning Line
Integrated solutions: Improve efficiency and quality; reduce labor costs.
Industrial Potato Sorting Line Solutions
GELGOOG’s industrial solution revolutionizes potato processing with an advanced “precise grading first, then efficient cleaning” workflow. Constructed with food-grade stainless steel, it guarantees hygiene and easy maintenance. Pre-grading significantly cuts down water/energy use and waste, while ensuring optimal cleaning for each grade. This process maximizes final product quality and yield, delivering a reliable supply of high-quality raw materials for your deep processing needs.

The video below provides a direct visual demonstration of the superior performance of GELGOOG’s automated potato grading and cleaning production line. From potato feeding and grading to cleaning and packaging, the entire process runs smoothly, fully showcasing our technological prowess.
Automatic Feeding and Soaking Cleaning
Potatoes enter the soaking tank for initial cleaning and impurity separation in clean water. Multiple high-pressure fan-shaped nozzles are installed at the elevator inlet, forming a covering water curtain during the lifting process to perform a secondary rinse on the potato surface, thoroughly removing residual mud and sand.
- The dual cleaning design of soaking and spraying ensures deep cleaning, effectively removing impurities from the surface and crevices.
- A circulating water filtration system significantly reduces water consumption, meeting environmental protection production requirements.
- Made with food-grade materials, all contact parts meet food safety standards, ensuring product hygiene and quality.
Roller Grading System
Potatoes enter a grading system composed of parallel rollers, with the gaps between adjacent rollers gradually increasing. Under constant rotation, the potatoes continuously tumble and move forward. When their size is smaller than the current gap, they naturally fall into the corresponding collection trough, completing precise grading.
- The roller gaps are flexibly adjustable, adapting to different grading standards without replacing parts. Operation is simple and conversion is efficient.
- Each roller is independently driven, so even if one roller malfunctions, the system can continue operating, ensuring production continuity and stability.
- The roller surfaces undergo special polishing treatment, making them smooth and wear-resistant, effectively preventing scratches on the potato skin and maximizing product quality.
Bubble Cleaning Unit
Graded potatoes enter the bubble cleaning tank. A dense bubble generator at the bottom produces thousands of bubbles, effectively removing surface dirt and sand through physical rubbing. Combined with a circulating water filtration system, this achieves highly efficient cleaning.
- Micro-nano bubbles penetrate crevices for deep cleaning, thoroughly removing stubborn stains from crevices.
- Water flow intensity is precisely calculated to ensure effective cleaning without damaging the surface.
- The circulating water system significantly reduces water consumption, aligning with green production and environmental protection principles.
Secondary Brush Cleaning
Potatoes undergo a fine surface polishing process using a specially designed brush roller assembly. Food-grade bristles, combined with atomized spray, achieve this. Adjustable roller speed accommodates different cleanliness requirements, enabling personalized treatment.
- The differential rotation design creates a three-dimensional cleaning network, removing surface impurities without blind spots.
- The bristle hardness is scientifically formulated to protect the potato’s natural skin while cleaning.
- The modular layout facilitates maintenance and replacement, significantly reducing equipment operating costs.
Air-drying and Draining System
Utilizing a dual-channel air-drying design, surface water droplets are first removed by a high-pressure fan, followed by thorough drying via a low-temperature air curtain. A unique buffer section allows potatoes to drain naturally, improving drying efficiency.
- Multi-stage air-drying technology ensures complete surface drying, laying the foundation for subsequent packaging and storage.
- The application of an energy-efficient control system significantly reduces operating costs and improves economic efficiency.
- Wind speed and direction can be precisely adjusted to adapt to different seasons and ambient temperature changes.
Packaging Terminal
Dried potatoes are sorted by grade and fed into the corresponding packaging line, where they are automatically weighed, bagged, and sealed. Packaging specifications and styles can be customized to meet customer needs, enabling personalized output.
- An intelligent identification system accurately matches packaging solutions, significantly improving packaging efficiency.
- A flexible conveyor design avoids mechanical damage in the final stage, ensuring product quality.
- A data management system records complete production information, meeting traceability requirements.
