Decortication of hemp is a process that involves the separation of the fibrous outer layer (bast) from the inner woody core (hurd) of the hemp plant. This process is critical in the utilization of hemp for various industrial purposes, as the bast and hurd have distinct properties and applications. The bast, for example, is used for fiber applications such as textiles and composites, while the hurd is used for animal bedding, construction materials, and other cellulose-rich applications.
Historically, the decortication process has been relatively inefficient and damaging to the hemp fibers. Traditional methods employ a hammer mill or a slow-motion "beating" action, which can weaken and even damage the fiber bundles in the bast, effectively limiting their potential use in reinforcement applications. Likewise, these methods can also lead to the attrition of hurd fiber, leading to the production of powdered hurd. This powder can contaminate the green microfiber that contains valuable CBD and other nutrients, making the separation of clean green microfiber nearly impossible.
A new era of hemp decortication has dawned with the introduction of advanced processing technology. This innovative approach leverages high-speed kinematic action, which meticulously separates the hemp straw into high-value products without causing damage. It produces structurally intact bast fibers and successfully captures a clean green microfiber stream that is rich in CBD and other nutrients. This clean green microfiber stream is of high value in many applications, offering a new revenue stream for hemp processors. The advanced technology's effectiveness and efficiency have revolutionized the hemp decortication process, paving the way for the profitable and sustainable use of this remarkable plant.
