ABSTRACT:
Present-day harvest methods for sweet sorghum are labor intensive, and/or require that large quantities of matter be removed to a central location for processing. A field harvester for sweet sorghum would cut the crop and reduce it to its separated juice and solids in the field. A cutter/feeder unit cuts the crop off and feeds it into a multiple roller press where most of the juice is removed. An optional screw press may be used to further remove juices from the solids. The solids are filtered from the juice using an endless belt filter press unit. The pH of the juice may be adjusted by the addition of some acid to inhibit bacterial action. The solids may optionally be pelletized for use as livestock feed or for fuel. The juice is temporarily stored on the harvester in a mounted or pull-behind tank before it is transferred, ultimately, to a nearby storage/processing location.
