Key benefits

Consistent product quality

The SORTEX A uses high-resolution cameras to detect either light or dark defects. This includes detecting either color defects in your products or removing foreign materials. This can help you to achieve a consistent quality of products.

Automatic sorter calibration during setup

The sorter setup is simplified by its machine learning features such as automatic calibration and product tracking. Also, you need to spend less time on continuous monitoring and adjustments.

Optimizes yields, minimizes waste

The SORTEX A comes with machine learning. Its product tracking software analyzes each grain and classifies it either as accepted or rejected, minimizing false ejection of good grains.
