Seed cleaning removes impurities, ensuring compliance with industry standards and improving crop yields. Our automated systems separate seeds by size, density, shape, and color—ranging from small breeding stations to large manufacturing. With labor shortages and stricter regulations, we offer dust-free, self-cleaning solutions for a safer, more efficient process. Test your seeds in our Experience Center!

About Cleaning

Seed cleaning is a fundamental process in seed operations. Machines are used to remove unwanted impurities such as dust, chaff, stones, weeds, and plant debris. This step enhances seed purity and ensures the industry’s quality standards and legal requirements for shipping seeds around the world. Phytosanitary measures are taken to prevent the spread of harmful pests, diseases, or invasive plant species across borders.

Clean seeds not only have a higher market value, but also perform better after planting, leading to better crop yields.

Modern seed cleaning systems use proven technologies by separating seeds based on size, density, shape and colour. These machines are available for processing from grams of grains to tonnes. The technologies are used for breeding stations to seed manufacturing stations.

We offer semi-automatic basic systems to fully automatic self-cleaning and controlling conditioning systems. For example, seed de-bearding, polishing, brushing, scalping, air screening, belt grading, sizing, calibration, density and gravity separation. Both stand-alone equipment and fully integrated processing lines are available in our range. Did you know that we can test your seeds in our experience center with the above technologies?

With the growing challenges of limited staff and stricter environmental and labour regulations, seed companies need to develop and improve their operations. In recent years, as an equipment supplier, we have recognised these requirements and developed closed, dust-free and automated Clean-in-Place machines. Challenge us and show us our innovative solutions for a safe working environment.

Hand-sieves

Magnetic Seed Separator

Magnetic separation is perfect to separate seed lots which contain weeds (e.g. gallium), soil parts, germinated or damaged seeds by using iron powder, water and applying an unique magnetic separation technology.

Seed Air Cleaning

Air separation is extremely suitable to divide chaffs or empty seeds from viable seeds. Using technology based on density differences, the purity and germination capacity of the seed lot will be improved.

Seed Air Screen Cleaning

Air screen cleaning is absolutely suitable for separation of chaffs, soil and or stones from seeds in order to improve the seed purity (this procedure is the start in every seed cleaning process).

Seed Belt Grader

Belt grading is ideally suitable for the separation of round shaped seeds from flatter shaped seeds or particles like plant fibers or flower stems when sorting brassica’s, spinach and or beet seeds.

Seed Blender

Blending (mixing) is very suitable to create a homogeneous seed lot of different lots of the same variety.

Seed Calibration (Sizer)

Calibration (sizing) is highly suitable for exact flat sizing of seeds based on the size (diameter), using high accurate screens, with the objective to create a uniform plant growth.

Seed Gravity (Density) Separator

A Seed Gravity Separator is definitely suitable for the quality upgrading of seed lots, by making a separation between the different particle densities.

Seed Indent Cylinder

An Indent Cylinder is very suitable for separating seeds based on length. This technique is highly suitable for separating e.g. chaffs from elliptical shaped seeds like lettuce or carrot seeds.

Seed Polishing

Polishing or brushing of seeds is eminently suitable for making seeds smoother and therefor they have a better sow ability like e.g. tomato, carrot, spinach and beet seeds.

Seed Spiral Separator

A Spiral Separator is idealy suitable for separating round shapped seeds from flatter shaped seeds or the separation of sclerotia from radish or cabbage seeds.
