an automated process for cleaning fruit bins , and particularly grape bins , deploys a conveyer system in which bins are simultaneously rinsed on the inside and outside in an inverted position . two rinse cycles are rapidly completed with the conveyance of the inverted bins through a wash station . the wash station deploys a pivoting v - shaped spray rod inside the bin , below the conveyor track , while the outside is rinsed by a second surrounding inverted v - shaped spray bar that moves transverse to conveyor direction will the bin is stationary inside the wash station . a pivoting l - shaped arm with an integrated conveyor track move the bins on or off the central conveyor , while flipping them 90 degrees . two such conveyors return the bins to an upright position for use and stacking . the water from a first rinse is optionally screened and treated before its use to rinse subsequent bins .
