Length Grader
Length Grader (Nubbin Grader)
Uniform fry length is an important part of frozen potato product handling, especially when consistent sizing is required before weighing and packaging. A length grader for the Netherlands separates French fries according to length, helping manufacturers achieve more consistent product classification.
The Nubbin Grader is mainly used for frozen French fries and similar potato products. Its screening arrangement separates fries into different length ranges while allowing continuous product movement through the machine. This can reduce the need for manual sorting and support more consistent downstream handling.
The grading surface can be configured with customised perforations according to the required length range and product characteristics. With a width of 500–1000 mm and capacities of 5 TPH and above, the equipment can be used for higher-volume frozen food lines.
Built using SS 304, SS 304L and rigidised sheet, the length grader is suitable for food handling environments where hygienic construction and easy maintenance are important. It can be integrated with conveyors, weighing systems and other material handling equipment for production lines in the Netherlands and across Europe.
