The Ellips CleanFlow Pre-Sorter is a pre-sorting solution for potatoes and onions designed to remove stones, clods, extreme defects, foreign objects and debris before they reach storage or the grading line. Powered by Ellips True-AI, the system detects unwanted material and defects at high throughput.
True-AI detection of defects and unwanted material
Ellips True-AI scans potatoes and onions moving through the line, detecting stones and clods, foreign objects, debris, rotten product, green, growth cracks, misshapen product and mother tubers before they progress further through the process. The system provides a cleaner batch whether the potatoes or onions are heading into storage or to the grading machine.
Protects storage and grading equipment
The CleanFlow Pre-Sorter removes stones, clods and extreme defects before they reach storage. According to Ellips, these materials can occupy storage capacity, consume cold-storage energy and allow defective produce to affect good potatoes and onions. The system also removes stones and clods before they reach the grading machine, helping protect rollers, cups and belts from damage.
Up to 80% reduction in manual pre-sorting labour
The CleanFlow Pre-Sorter automates the manual work of removing stones and clods by hand. According to Ellips, the system can save up to 80% on manual pre-sorting labour, reducing a five-person intake team to one person. The CleanFlow Pre-Sorter handles up to 120 tonnes per hour, allowing intake to maintain throughput during peak harvest periods.
Five widths from 1 to 3 meters
The CleanFlow Pre-Sorter is available in five widths ranging from 1 to 3 meters. Its compact, robust design is intended to fit into existing setups, with configurations suitable for operations ranging from a single farm line to a full industrial grading operation. The CleanFlow Pre-Sorter removes unwanted pieces individually and uses a controlled 35 cm drop for potatoes and onions. According to Ellips, potatoes and onions move through the system without bruising, even at full speed.
Low-maintenance operation and one-day installation
The CleanFlow Pre-Sorter is designed for simple, low-maintenance operation and daily use on farms and in packhouses. The system is designed to continue operating as harvest conditions change and can be added to an existing line with plug-and-play installation in one day.
