Eqraft Optical grader

The Eqraft Optical Grader sorts onions at high speed by quality, size, weight, shape and color based on internal and external checks.  

To ensure the best possible optical inspection, the onions are cleaned by means of advanced air extraction units before and during the grading process. This also keeps the machine clean from excessive dust and skins. The Grader uses the dark chamber principle and near infra red for retrieving the most reliable information about the internals of the onion. To prevent blurred images, each onion is held stationary in a cup during inspection. Next, the onion is assessed externally from two different positions to determine color, skin condition and sizes.

Finally, the onion is weighed and deposited in the assigned exit as set up by the operator. As each product has been inspected and rated you also gain the opportunity do something with this data e.g. to grade off specific volumes to fill niches or specific orders.
