SYSTEM AND METHOD FOR PROCESSING GUAYULE RUBBER

A guayule rubber processing system and method involves mixing a guayule rubber and at least one solvent blend in an extruder, in order to remove resin found in the guayule miscella and to precipitate the guayule miscella to form a precipitate. The at least one solvent blend has a first solvent confi...

Beschreibung
Zusammenfassung:	A guayule rubber processing system and method involves mixing a guayule rubber and at least one solvent blend in an extruder, in order to remove resin found in the guayule miscella and to precipitate the guayule miscella to form a precipitate. The at least one solvent blend has a first solvent configured to precipitate the guayule rubber, and a second solvent configured to swell the resulting precipitate. In particular, a series of the solvent blends may be used at different locations along a length of the extruder and may further include distinct blends of the first solvent and the second solvent, introduced at the different locations, and having different ratios of the first solvent and the second solvent.
