ABSTRACT:
An improved system for extracting soluble substances from fibrous material by using a plurality of maceration and compression steps thereby excerting moderate pressure on the fibrous material up to 15 bars.
Arrangements are made to saturate the fibrous material to its maximum absortion potential between each pressure application. Moisture content of the agent fibrous material is finally reduced with the combined application of moderate and high pressure. The application of imbibition liquid in this area and the use of the solvent received for the purpose of maceration in the preceeding extraction steps is made in accordance with the respective concentration of the solvent.
The extraction system can operate without the application of process heat; therefore, a lixiviator is not required. Two or more maceration and compression steps can be located in a module, thus permitting a very compact arrangement of the extraction system.
The extraction time is reduced below 4 minutes, allowing in combination with reduced temperatures, the processing of thermolabile substances. The system is particularly suitable for the extraction of sugar from sugar cane.
This invention relates to a new improved apparatus for removing or extracting, by the use of a suitable solvent or solvents, soluble substances from subdivided fibrous materials as exemplified by the extraction of sugar cane.
