wavey arrows 96 in fig6 these relatively firm raisins will land on the inclined chute 26 so that they fall onto the middle conveyor 12 the second or middle conveyor 12 is advantageously used to effect a finer degree of sorting of the raisins since some mold damaged raisins will be bounced off of the first conveyor 10 due to the relatively slow conveyor belt speed of the first conveyor coupled with the relatively high frequency of the slapping action accordingly the belt of the middle conveyor 12 is moved at a somewhat greater speed than that of the first conveyor 10 transporting the raisins landing thereon over a first slapping mechanism 50b which is run at a somewhat slower slapping frequency than that of the mechanism 50a in the first conveyor those raisins which are not bounced off of the second conveyor 12 by the action of its first slapping mechanism 50b are transported over a second slapping mechanism 50c which is operated at a somewhat slower slapping frequency than is the slapping mechanism 50b those raisins which are bounced off of the side of the second conveyor 12 are advantageously caught on the third conveyor 14 for final sorting the belt 28 on the third conveyor 14 is moved at a relatively high rate of speed preferably between 20 and 30 feet per minute this conveyor 14 conveys the remaining raisins sequentially over a pair of slapping mechanisms 50d and 50e the first slapping mechanism 50d on the third conveyor 14 is operated preferably at an intermediate slapping frequency approximately 250 to 350 slaps per minute while the final slapping mechanism is operated at a relatively low frequency preferably about 200 to 250 slaps per minute as a result of.
