It is essential to minimize seed coat checking and splitting during all stages of physical handling of dry beans (Aguilera and Rivera 1990). Bean seed coat damage is cumulative during each stage of handling from harvest to final distribution and preparation. Damage is most readily associated with mechanical dropping and shattering during conveyor transfers. Augers and poorly designed bucket lifts are particularly detrimental and result in high checked seed coats due to shearing action and fractional abuse to the seed. Conveyor belts that result in stationary aggregated beans during conveyance are superior to system designs in which “individual beans are dynamic” resulting in bean‐to‐bean and bean‐to‐conveyor abrasion.

Bean dropping has a profound influence on seed coat damage (Shahbazi et al. 2011). Emptying of combine bins into wagons or trucks and truck unloading during elevator receipt can result in severe bean impact. The filling of bins and silos or dumping into free‐standing piles are areas where significant seed coat damage may occur. It is recommended that minimum drop distances be maintained. It is recommended to establish a continuous flow from truck to bean pile rather having beans striking floors or grates when pit dumping. The length of drop into the bin is critical to control seed coat damage. Bean ladders are used to reduce the “free fall of beans” when they are filled into the storage facility. Construction of bean ladders within bins and silos enables beans to descend by sliding on a spiral ramp to levels ranging from the floor to any subsequent elevation within the storage structure.
