Improve your potato grading results with Ellips' TrueSort

Potato Grading

Technological advancements (i.e., HD cameras, LED lighting, increased processing speed, etc.) have enabled a dramatic improvement in potato grading technology over the past 8 years. This specifically applies to external defect capabilities.
Ellips has been at the forefront of this development with its TrueSort grading and sorting solution which provides unmatched capabilities as it relates to all aspects of potato grading.
Two principles of transportation of potatoes under the camera are supported in Ellips Software: rollers or belt machines.

WEIGHT

The weight of every single potato can be measured on a cup system or roller system with built-in weighing system.
Accurate weightings (+/- 1 gram) are possible, even at high speed (up to 15 cups/second).
The system automatically corrects the weight by taking into account factors such as temperature differences and dust accumulation throughout the day.

Weight in belt systems can be calculated from camera pictures of every single potato by an adjustable specific weight parameter. This weight enables the operator of the machine to monitor an average product weight and capacity per hour in the dashboard that is build-in in the Ellips TrueSort software.

SIZE

The size module measures properties of the potatoes for which the contour is used. The measurements have been made more reliable by looking at the product from various angles. The potato is rotated under the camera several times and multiple images are taken of the same product. In this manner we can measure the diameter, length, and surface area. Square Measure is a specific Potato sizing criteria which is implemented in the Ellips TrueSort software.

Defects in shape can also be detected, It will also be detected when two products are positioned between rollers. By rotating the products, up to 40 images are made of each product. In the Ellips TrueSort Software Imperial units or Metric Units can be selected for Weight and Size classes.

COLOR

Ultrafine color separations are obtained through TrueSort’s intuitive software that enables operators to quickly create or modify color profiles for Red, White, Yellow or Sweet potatoes. Using the color module, you can – based on live feedback from the cameras – determine the color on which you want to grade the product. (for example, the average color of a potato).

EXTERNAL QUALITY

For external quality, Ellips incorporated HD cameras and LED lighting into our TrueSort vision system years ago while some competitive solutions have only recently begun to utilize these technology advancements. While the use of HD cameras enables better defect visual identification, it also creates massive amounts of data that need to be addressed with increased processing power and more sophisticated software algorithms in order to be beneficial. Ellips has developed and refined the processing and software capabilities necessary to leverage these technology advances while the competition is still working to optimize the use of this advanced enabling technology. Ellips customers can quickly establish “variety specific” grading parameters that provide consistent detection of the most prevalent external defects (i.e., Common scab, Black scurf, Silver Scurf, misshapen/doubles and mechanical damage and punctures). Once the defects are identified, TrueSort software sorts the potatoes into various classes based upon thresholds established for defect severity, count or area.
