Abstract: An entire harvested ground fruit load is subjected to a first cleaning process on a cleaning table, which separates the smaller ground fruits, soil, stones, clods, vine stems, grasses and other debris from the larger ground fruits. The fall-through burden from the cleaning table is subsequently subjected to a second separation step using a pintle belt conveyor equipped with at least one spinning shear roller. Soil particles, stones, clods, vine stems, grasses and other debris fall between the pintles of the pintle belt conveyor and are discarded, while small ground fruits are moved by the spinning shear roller(s) and either recombined with the main ground fruit load or diverted to a separate path for storage. Operational speed of the pintle belt conveyor and rotational speed of the shear rollers can be adjusted to maximize the breakup of clods which impact the shear roller(s).
