Are you struggling to identify and sort out onions that have challenging defects?

A task that is made even more difficult due to huge variations in onion quality across seasons, batches and varieties. Working with growers and packers around the world, we know that the world of onion production is challenging and fiercely competitive. Nevertheless, every day you must meet the strict market standards for quality, size, shape, color and overall appearance.

Following are the top challenges you might face, but don’t worry, we’ll also explore some solutions to ensure consistency and maximize your returns.


#1. Defects and diseases will damage your brand reputation.


Because of variable weather & growing conditions, each season has different, or more prevalent, defects which makes it challenging to deliver consistent quality. Extreme weather events, and ever stricter regulations on pesticide use, can have a big impact on onion quality. On top of that, disease, bacteria and fungus can can cause a range of different internal defects that are extremely difficult to detect.


#2 Rejection hurts your business.

It only takes a small % of defective onions to dramatically increase the risk of rejection. More than ever, it’s important for growers to meet the ever-changing requirements and quality standards. On top of that, you must meet your volume and on-time commitments while preserving the consistency and quality of your packed product. That’s why it is critical that you do everything possible to ensure that each and every onion ends up in the right place.


#3. Uniformity in a world with a lot of sizes, shapes and quality differences.

Every onion is different. So is every defect. Internal and external defects occur in many ways and can vary from season to season and batch to batch. This variability in size, shape and quality makes it challenging for manual graders to consistently sort onions into uniform grades, which can affect their marketability.  


Sorting by hand is outdated, automation is the industry-standard.

To address the above challenges, automation of the grading and sorting process is increasingly being seen as the only way to efficiently achieve the desired quality on a consistent basis. Automation provides the added benefit of being able to maximize the value of each onion and to easily modify grading standards to address the unique needs of your customers.  On top of all that, the reduction in labor costs can significantly impact your overall returns.

Onion External Quality Grading

#2. Internal defects have nowhere to hide.

Your onion may look perfect on the outside, but the internal quality may be a different story. Onions can be affected by various internal diseases or defects. These internal problems, such as core rot, ring rot, sprouting, are not good and cause a chain reaction, as onions with internal problems can infect other onions during storage or export. With the Ellips TrueSort internal quality system, you can see through the entire onion (instead of just underneath the skin) and accurately detect internal defects. By virtually slicing the onion into pieces (up to 20 scans), you can examine and recognize these defects at lightning speed. Sometimes it’s even possible to detect internal diseases at an early stage.


"The new packing line has successfully met quality targets. The system’s internal defect detection is considered top-notch and even exceed industry standards"
