摘要： An extractor suitable for using a solvent to separate a compound from a solid or semisolid substance containing the compound. The extractor includes a conveying assembly having an inclined conveyor for receiving the substance from a substance inlet and moving the substance through the solvent, an inclined upper surface associated with the first conveyor and an inclined lower surface associated with the first conveyor. The conveyor is configured to move the substance downward through the solvent along the upper surface toward a lower end of the conveyor and upward through the solvent along the lower surface toward an upper end of the conveyor.

摘要： Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).
