Dunns have sophisticated skinning machines called “decorticators” installed in the production line, these are a series of abrasive stones that physically rub the skins off the pulse. The skins are aspirated away from the skinned / decorticated product and are conveyed into a bulk trailer for animal feed.
After skinning, the peas can either be split or polished (or both) depending on the customer’s requirement.
Splitting pulses is achieved by pushing the product through oscillating knives, this causes the products to split down the cotyledon (central scar) and split into two even halves.
Polishing of the product with inert talcum powder helps gives the product a much more aesthetically pleasing appearance; it also reduces the levels of dust and flour within the product to a satisfactory level, as dust can cause issues with heat sealed packaging.
