ABSTRACT:
A system for harvesting and processing aquatic plants growing on the surface of a body of water includes a shore mounted harvesting apparatus which gathers the plants from the surface of the water and conveys them to a first chopper assembly which rips and shreds the plants to a first manageable size. The harvester assembly includes a first rotating drum positioned in the water which forces the plants upward and into engagement with a second rotating drum having a plurality of spiral wound vanes which engage the material and forces it along the passageway into further engagement with a third rotating drum which cooperates with a cutting bar to serrate and shred the material. The shredded material is thereafter transferred to a chopping assembly which comminutes the aquatic plants into very small pieces. The comminuted plants are first pressed and then transported to a mixer dryer assembly which includes a large vat for receiving the comminuted plants and a plurality of stirring arms arranged in an interrupted feed screw pattern. The stirring arms continuously stirs the material causing it to move from one end of the vat towards another from where it can be selectively recirculated externally of the vat until sufficient drying is achieved. The mixer dryer apparatus has provision for being temperature controlled both by a water jacket arund the vat and by passing heated air over the top of the stirred mixture. If desried, the plants may be mixed with other material to form an animal feed product.
