ABSTRACT:
A system for extracting soluble substances from fiberous material by lixiviation is followed by various steps of compression and maceration exerting moderate compression on the fiberous material up to 14 Bar. Hereby, special arrangements are made to saturate the fiberous material to maximum absorption between each pressure application. Moisture content of the spent fiberous material is reduced with a special roller assembly with the application of low and high pressure. Heat is used to facilitate the extraction process and to suppress biological alterations of matter involved. With heat exchange between raw material and extracted solvent, overall heat economy is improved. Fiberous material is used as filter aid to reduce contamination of extracted solvent with foreign matter. The system is particularly suitable for the extraction of sugar from sugar cane.
