Agricultural seed sorting

Bühler optical sorting technology improves the homogeneous appearance of seeds for better germination levels and consistent growth rates.

Our optical sorters are designed to deliver maximum germination of seeds. They detect unwanted colors, subtle discoloration, size and shape defects, and foreign materials. The accuracy of our technologies not only improves the homogenous appearance of your final seed quality but also ensures consistent growth rates. Depending on the model, we can also successfully sort smaller seed varieties such as carrot, onion and lettuce.

Highlights

A three-in-one color, shape and size sorting

The Sortex A MultiVision features high-resolution cameras, LED lighting and machine learning software to detect very subtle discoloration, shape defects and foreign materials.

Applications

Sunflower Seeds

Corn / Maize

Soya Bean

Different varieties of sunﬂower seeds such as black, striped or white have varying defects and processing requirements. Using a combination of Bühler proprietary technologies including Enhanced InGaAs and PROﬁle TM , the sorting sample shown above successfully removed sclerotia, ﬂower heads, xanthium seeds and sticks.

Our range of optical sorters can sort a wide range of corn varieties including both white and yellow ﬁeld corn, popcorn and sweetcorn. SORTEX can successfully remove diseased corns, insect damage and broken corns for maximum germination. The application can also remove foreign seeds to eliminate cross contamination.

Raw soya seeds from the ﬁeld have high levels of cross contamination. In the sorting example shown above, corn, other bean varieties, foreign materials and oblong shaped soya seeds were successfully removed to deliver a consistent homogeneous appearance. For maximum germination, the sorting application also removed immature, brown and black soya seeds.
