Abstract

L'invention a pour but de permettre l'utilisation à grande échelle de troncs de palmiers entiers en séparant des faisceaux vasculaires et des tissus parenchymateux des troncs de palmiers à l'aide d'une structure relativement simple. La solution selon l'invention porte sur un matériau en plaque mince obtenu par tranchage mince d'un tronc de palmier à huile à l'aide d'un lacet rotatif (1) qui est broyé par des broyeurs (4, 5). Les fragments écrasés sont classés par gravitation par un classificateur gravitationnel (7) pour collecter des faisceaux vasculaires à partir d'une fraction lourde classée par gravitation et collecter des tissus parenchymateux à partir d'une fraction légère classée par gravitation.
