Scotts Evolution Separator For Vegetables

The range of Evolution Separators received a host of upgrades and improvements designed to reduce maintenance and increase performance. Their primary role is to gently separate clod, stones, haulm and loose soil from a range of fruit, vegetables and alliums.

The Evolution Separator works by extracting the debris between 2 contra rotating rollers. The larger roller (spiral roller) has air chambers and is deformable with a spiralling rib. The smaller roller (clod roller) is smooth with a choice of finishes. The clever design of the “spiral rib” entrains the debris down into the valley between the rollers where, if the debris if soft enough is then crushed and ejected down below the separator. Stones will also pass between the rollers as the “spiral roller” readily deforms around the stone so does not allow losses of crop at this time. If larger stones enter the valley and there is not enough deformation in the spiral roller there is a safety mechanism that allows the clod roller to spring away momentarily to allow the stone to pass through.

Every roller is independent and adjustable thanks to its own inverter. This way, it is possible to get a valuable final product even in very wet conditions with 80% of soil and only 20% of potatoes, the Evolution also removes potato tops.

The Evolution cannot work independently and must be integrated into a grading line.

Our story began when Geoff Haith, at just 18 years old, started carrying out repairs for local farmers. Through this work, he recognised a need for more efficient, mechanised solutions for washing and grading root vegetables. Combining his engineering expertise with a strong farming background, Geoff went on to design and manufacture innovative machinery for handling carrots, potatoes, and beetroot.

Until recently, the business was led by Geoff’s five sons and daughter, supported by a talented and forward-thinking management team dedicated to ensuring the company’s continued success. Today, Haith employs over 120 people at our UK factory and works with a network of agents worldwide, promoting the Haith brand globally and delivering high-quality installations and satisfied customers across the world.

Over the years, Haith has continued to grow in both size and capability, relocating three times to accommodate expanding operations. This growth has culminated in our current ultra-modern, wholly owned facility in South Yorkshire, featuring approximately 6,000 m² of production space on a six-acre site. The factory is equipped with the latest CNC laser, waterjet, and bending technology, enabling us to maintain the highest standards of precision and quality.

Haith has received numerous awards for machine design and innovation. We are especially proud to have been honoured twice with the UK’s highest business accolade, The Queen’s Award for Enterprise, both in the Innovation category. As the only company in our field to hold this prestigious award, our commitment to continuous innovation and development—helping to keep the UK vegetable industry at the forefront of technology—has been clearly recognised.
