If the water in a traditional sample barrel washer is not changed regularly, it can quickly start to smell, as well as harbouring bacteria. This can lead to inaccurate shelf-life assessments of the washed samples.
The Washer Grader from Suffolk-based Niagri Engineering uses Cleanwash 25 fresh-water cleaning system to overcome these issues, but adds enough features to make assessment of the most variable sample easy.
The company claims that the unit, which uses four changeable rubber screens to size-grade the sample once washed, makes it possible to evaluate a 25kg sample in less than five minutes.
A chute takes the different parts of the sample to a weighing platform and the machine features bins for reject potatoes, side steps and a holder for 25kg paper sacks.
The Niagri Washer Grader is available in painted or stainless steel finishes and mounted on castors for easy movement.
