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.

Here at Haith we are proud to say that we are one of the only companies in our sector to be continuously owned by the same family since the company was founded.
It all began when, at 18 years old, Geoff Haith started carrying out repairs for local farmers leading him to realise that there was a need for a more mechanised way of washing and grading root vegetables, with his engineering ability and farming background he designed and manufactured machines for carrot, potato and beetroot handling.
The business, until recently, has been run by Geoff’s five sons and daughter, backed by a great young management team to ensure the continued success of the company, there are over 120 people employed at our factory in the UK and multiple agents around the world promoting the Haith brand globally resulting in a network of excellent installations and satisfied customers worldwide.
Haith has continued to grow in size and strength and has moved on 3 occasions to larger premises with more production area, this has led to the present ultra-modern wholly owned facility with around 6,000 m² of production space on a 6 acre site in South Yorkshire which is equipped with the most up to date CNC laser, waterjet and bending equipment.
Haith have achieved many awards for machine design over the years and are especially proud to have twice been awarded the highest accolade in the UK, The Queen’s Award for Enterprise, both times in the Innovation category, as the only company in the field to hold this prestigious award, Haith’s emphasis on continual innovation and development with a view to keeping the UK vegetable industry at the forefront of technology has been acknowledged.
