ABSTRACT:
An improved harvester for harvesting a salt crop from the bottom of a shallow, elongated solar crystallizer containing a substantially saturated salt solution overlying the salt crop. The harvester includes track means extending longitudinally along the sides of the crystallizer on which a pair of carriages are movably mounted and support the ends of a frame extending transversely across the crystallizer. The frame includes salt gathering means for transferring the salt crop laterally in the form of one or a plurality of longitudinally extending furrows or ridges in response to the travel of the harvester along the tracks and the resultant gathered salt is extracted by one or a plurality of suction inlets disposed in alignment with the furrows in the form of an aqueous brine slurry. The extracted salt crop is subsequently separated and recovered while the liquid brine is returned to the crystallizer. The harvester enables the harvesting of a solar salt crop while retaining a protective layer of substantially saturated brine over the salt crop while simultaneously maintaining a salt floor or bottom in the crystallizer of a preselected thickness.
