<p>Machine comprises one, or several superimposed, gravity flow cleaning unit(s). A mixt. of peas and waste is fed down an inlet throat to fall on to a rebound plate set at a predetermined angle to the horizontal. Each good pea bounces off the rebound plate to follow a trajectory which carries it over a dropout gap followed by a vertically adjustable barrier. The pea drops into an exit for good peas or on to a chute leading to the exit. Waste material and reject peas do not generally bounce high enough to clear the dropout gap and those that do are directed back by the barrier. The width of the feed throat is pref. adjusted so that the layer of mixt. directed on to the rebound plate has a thickness of approx. one pea. The cleaner is pref. multi-stage with reject material from stage one entering the inlet throat of stage two and so on. Cleaning peas ready for processing for canning, freezing etc. The cleaner has to remove pieces of pod, leaves, stalk, weeds, stones, soil, insects, moth grubs etc. also deformed and poor quality peas.</p> |
