How to produce hard gums ? Hard gums are produced by using a thickener, for example acacia gum, a resin from the acacia tree that grows in Sudan, Niger, Chad, Senegal, etc.
With a machete, incisions are made in the acacia trees in order to obtain a resin. After a couple of weeks, the hardened resin is tapped by the farmer and is packed in jute sacks. These sacks are offered for sale on the gum market of Sudan.
The acacia gum arrives as rough material in big jute sacks at Joris. First of all, the gum is reduced into small pieces, then it is melted and meanwhile all the impurities (sand, tree-bark) are removed by means of a centrifuge. A transparent solution is obtained.
