In 2009, Dunns made the executive decision to upgrade its production facility and over the next year, invested over £2.5 million in a state-of-the art production line.

This line concentrated on efficient processing, increasing quality and output whilst reducing labour.

Dunns analysed previous complaint trends and highlighted that stones have previously been an issue within the product, therefore a decision was made to ensure the risk of stone contamination within the finished product was brought to an absolute minimum. Therefore Dunns installed a double de-stoning system, coupled with laser colour sorting and X-Ray detection to ensure the product would meet every customer’s specification.

The latest technology was coupled with well-practiced techniques; these included recycling of product for re-grading to reduce losses and the installation of a TOMRA IXUS Bulk X-Ray sorter- the largest X-Ray machine in dried pulse processing in the UK.

Dunns chose an X-Ray sorter and Laser Sorter over the more traditional camera technology principally due to the dusty environment in which it is situated. As the camera technology requires a lens, dust can form a film over the lens causing deterioration in the sorting ability of the machine. However because both X-Ray and laser doesn’t have a lens this problem is avoided, leading to much more accurate and consistent sorting results.

The laser sorter is also very efficient at separating product by density and texture, this ensures contaminants such as stones / metal / glass are highlighted and removed.

 In December 2014, Dunns retained their A Grade BRC accreditation; Global Standard for Food Saftey, version 6 for Pulse processing and storage. Providing a proven, audited system that confirms Dunns’ food product safety, legality and quality.


Dunns are committed to adding further value to finished goods; this can be achieved by decorticating (skinning) and splitting dried pulses.

Dunns have a fantastic packing facility that allows product to be packed in a range of sizes from 10kgs to 2000kgs.

Dunns are fully accredited under a number of assurance schemes and we take pride in our food safety systems allowing us to have confidence in the quality of the product we produce.

Dunns’ traceability is a simple and effective system, giving customer confidence that any product processed at Dunns will be of the highest quality and can be traced from field to fork.
