Vegetable & Potato Flume De-Stoner

Geoff Haith designed and patented the Flume De-Stoner in 1971 and it is still being manufactured to this day.

The principle of this machine is to remove any stone and heavy clods from the vegetables before washing to eliminate any potential damage that may be caused to the crop or equipment further down the system.

Produce enters the machine and goes over an uplift of water which is controlled via a variable speed pump.

The different densities allow the crop to float over and the stones to sink down to the discharge elevator to be removed from the product flow. The produce is dewatered before entering the next process in the 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.
