By combining advanced AI grading, gentle product handling and high-speed processing, Elisam onion grading machines powered by Ellips True-AI help packhouses meet customer requirements while improving profitability.

An Elisam onion grading machine, powered by Ellips True-AI, uses advanced cameras and deep learning algorithms to inspect and classify every onion in real time.

The grading process includes:

• Accurate singulation to ensure every onion is individually assessed
• Rotating cups and 360° grading for full surface visibility
• Up to 60 high-resolution images per onion
• Analysis of size, shape, color, weight and external defects
• Internal quality inspection for hidden defects

The collected data is analyzed by True-AI, which classifies each onion according to the required quality standards and grading specifications.

This enables growers and packers to achieve consistent grading results, maximize pack-out and deliver reliable quality. Batch after batch.

Yes, Ellips True-AI continuously improves by learning from new data, helping the grading system become more accurate and efficient over time.

The system is trained using:

• Real-world grading data
• Customer quality control expertise
• Different onion varieties
• Multiple growing regions
• Data collected across seasons and conditions

By combining new data with its existing defect database, True-AI continuously refines its ability to recognize defects and optimize grading decisions. This ongoing learning process helps improve grading accuracy, consistency and long-term performance.

Elisam onion grading machines powered by Ellips True-AI are designed for simple day-to-day operation. The system automatically manages complex grading parameters, reducing the need for manual adjustments and operator input.

Benefits include:

✅ Easy-to-use operator interface
✅Automatic grading parameter management
✅ Fast product and grade changes
✅Reduced training requirements
✅ Consistent grading performance

When adjustments are needed, settings can be changed quickly and intuitively, allowing operators to maintain full control of the grading process.

Yes, Ellips grading technology can be integrated into your existing sorting machine through a retrofit solution. This allows you to upgrade to AI-powered grading without replacing your entire machine.

A typical retrofit includes:

• High-resolution camera technology
• New Ellips electronics and hardware
• TrueSort software
• True-AI grading technology

This improves grading accuracy, consistency and performance while reducing investment costs compared to purchasing a completely new sorting machine.

In practice, defects in the final product are typically reduced to below 2%, while only a small percentage of good onions is removed during sorting.

Elisam onion grading machines equipped with Ellips True-AI deliver highly consistent and objective grading results. By eliminating subjective human judgment, the system reduces variability and minimizes grading errors, even at high processing speeds. As the system processes more data, True-AI continues to improve its ability to detect and classify defects accurately.

Ellips True-AI inspects the entire surface of every onion and detects a wide range of external quality defects with exceptional accuracy.

Detectable defects include:

• Balding
• External rot
• Black mold
• Sprouting
• Misshapen
• Sour skin
• Mechanical damage/cut
• Green on white onions
• Color
• Watery scale
• Root tear
• Sun scald
• And many more

With detection accuracy down to 0.2 mm, the system delivers consistent and objective grading results.

Benefits include:

✅ Reduced customer claims
✅Improved pack-out rates
✅ More consistent grading
✅ Reliable shipment quality
✅Stronger customer relationships

Yes, with Ellips light transmittance technology, the system can grade the internal quality of each onion and detect hidden defects such as:

• Fusarium
• Internal rot
• Ring rot
• Neck rot
• Bulb rot
• Root plate
• New growth
• Twins

The Ellips Internal Quality system performs up to 20 high-speed internal scans per onion, virtually slicing the onion to reveal defects that are not visible from the outside.

Benefits include:

✅ Detection of hidden internal defects
✅ Reduced customer claims
✅ Fewer rejected shipments
✅ Improved product consistency
✅Greater confidence in delivered quality

Elisam onion grading machines typically process 2 to 4.5 tons per hour per lane, depending on onion size.

Capacity can be scaled through multi-lane configurations:

• 1 lane: 2-4.5 tons per hour
• 4 lanes: up to 18 tons per hour
• 8 lanes: up to 36 tons per hour

This high-capacity design helps packhouses handle peak volumes efficiently while maintaining consistent grading performance and meeting delivery deadlines.

Labor savings depend on your operation, product mix and current grading process. By automating grading, an Elisam onion grading machine can significantly reduce the need for manual sorting and lower labor costs.

Several customers have reported concrete results:

• Owyhee Produce (USA) installed their Elisam onion grader in 2019, then upgraded to True-AI in 2023 for enhanced defect detection. The AI upgrade helped reduce finish sorters from 2 per line to 1, cutting labor needs by 4 to 5 people overall, while making quality control and training easier to manage.
• Groka (Germany) reduced its sorting team from 10 people to just 2 — one operator and one post-checker. The Elisam grader also runs at full capacity for the entire 8-hour shift, compared to human workers who were only effective for about 5 of those 8 hours.
• Stourgarden (UK) now processes up to 200 tons of onions per day — more than their old mechanical grader — while cutting their grading team from 16 people to 6, reducing their labor bill by an estimated 40%.

Benefits include:

✅ Lower labor costs
✅ Reduced dependence on seasonal workers
✅ Fewer night shifts
✅ Higher throughput
✅ More consistent grading results

Yes, Ellips True-AI enables full-speed grading regardless of onion quality. The system maintains maximum processing speed while accurately detecting defects, even in mixed-quality batches.

Traditionally, batches with uneven onion quality often required slower processing speeds to maintain grading accuracy. With True-AI, this is no longer necessary.

Benefits include:

✅ Maximum throughput
✅ Accurate defect detection
✅ Consistent grading performance
✅ Higher operational efficiency
✅ More volume processed without compromising quality

Yes. For most onion growers and packers, an AI-powered grading machine pays for itself within a few seasons by reducing costs, increasing efficiency and improving product value.

Key value drivers include:

✅ Reduced labor costs
✅ Higher pack-out rates
✅ More consistent quality
✅ Increased throughput
✅ Lower waste and fewer claims

In addition to cost savings, AI grading helps maximize revenue by sorting onions more accurately into higher-value categories.

The exact return depends on your operation. Ellips and Elisam can provide a customized ROI calculation based on your volumes, labor situation and business goals.

The payback period depends on factors such as production volume, labor costs and the level of automation. In most cases, onion grading machines achieve a return on investment within a couple of years.

Typical savings come from:
