Then removing a large part of the bagasse from the suspension and getting miscella and the first portion of bagasse. Removing 80-95 wt % of bagasse from the miscella. It is possible to post-treat the miscella until a clarified rubber solution is obtained. By adding an additional polar solvent and/or by removing the non-polar solvent, rubber coagulation is carried out and a purified, hard rubber is obtained. EFFECT: invention makes it possible to reduce the cost of obtaining rubber from non-seringa plants. 7 cl, 2 tbl, 3 ex

Processes for the removal of rubber from non-Hevea plants

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).

Processes for recovering rubber from aged briquettes and aged briquettes containing plant matter from non-hevea plants

Provided herein are organic solvent-based processes for the removal of rubber from aged briquettes made from compressed guayule plant matter (briquettes). Also provided are aged briquettes made from the compressed guayule plant matter where the briquettes have been aged for either various time period after formation and the rubber within the briquette has retained its a molecular weight to within a specified range.

Methods for the desolventization of bagasse

A method for the removal of organic solvents from the wet bagasse having up to 45 weight % combined organic solvents and water includes heating the wet bagasse to a temperature of at least 100 C to evaporate the organic solvents and produce dried bagasse that contains no more than 1 weight percent organic solvents. Exemplary heating methods include the use of a dryer with multiple layers, the use of a dryer with multiple paddles or a desolventization screw extruder. The methods are particularly useful with wet bagasse from guayule shrubs. Removal of the organic solvents from the wet bagasse may allow for re-use of the organic solvents (e.g., if they are condensed and collected separately from the dried bagasse) and/or for use of the dried bagasse in further products (e.g., briquettes or pellets).
