摘要： The present invention relates to a process for separating natural rubber deriving from non- Hevea type plants, in the form of solid crumbs, from solutions in an organic solvent system including it, where said organic solvent system may comprise at least one nonpolar organic solvent, or a mixture of at least one nonpolar organic solvent and at least one polar organic solvent, and the concomitant removal of said organic solvent system from said rubber, where the aforementioned process comprises subjecting said solution to a stripping stage by means of water vapor, in presence of a dispersing system, separating the aforementioned crumbs of natural rubber from the liquid phase, obtained through the stripping stage, and subjecting said crumbs to drying.
