Process for recovering rubber from rubber-bearing plants with a gristmill

A process of recovering rubber from rubber-bearing plant materials in non-aqueous conditions by first drying the rubber-bearing plant material and then mechanically grinding the rubber-bearing plant material to produce rubber threads and finely ground root tissue. Following the mechanical grinding, rubber threads are separated from finely ground plant root tissue by passing the ground plant material over a dry vibrating mesh screen and blowing away the plant root skins to leave rubber threads. The rubber threads may further be purified by stirring the rubber threads in warm water. Then the mixture is settled and the rubber threads are skimmed off. Optimal purification may be obtained by stirring, settling, and skimming off the rubber threads. Another optimal purification can be achieved by stirring continuously in the flowing warm water.
