Abstract
An apparatus and process for extracting sugar from sugar cane in which a blanket of fiberized cane is passed through a series of compression and maceration operations. The compression is performed at low pressures (for example, 40 to 160 pounds per square inch) between a pair of rollers. During compression, the extracted juice is removed through the perforate surface of the lower roller. The extracted juice removed during compression is supplied as imbibition liquid to a prior operation.
Claims20
In an apparatus for extracting soluble substances from sugar cane, the combination comprising:
- means for fiberizing the sugar cane so as to substantially expose the cane juice,
- means for collecting the fiberized mass of cane,
- a first compressing means for expressing liquid contained in said fiberized mass,
- said compressing means having opposed upper and lower compression surfaces,
- said lower compression surface provided with openings therein for conducting a substantial portion of the expressed liquid therethrough during the compressing operation,
- means for macerating the fiberized mass prior to said first compressing means,
- means for supplying said maceration means with liquid expressed from said first compressing means, and
- means for removing liquid from said maceration means for supply to the final product.
