Abstract: An extrusion system for separating particulates entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of particulated water. A diffuser suspended within the tank converts the flow of particulated water into multiple transverse flows to avoid churning settled particulates. A particulate filter fixed within the tank includes a central channel surrounded by a cylindrical array of cantilevered parallel vertical blades. The channel directs the flows below the blades, causing dynamic movement of the blades as the particulated water rises therebetween to trap particulates along boundary layers, promote particulate settling by gravity, and allow clarified water to rise to the top of the tank. A sensor detects settled particulate reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated particulate from the bottom of the tank.

Abstract: An adjustable roll sizer for sorting objects of different sizes includes a first set of rollers mounted to a support structure and arranged in a first parallel array. A second set of rollers is mounted to the support structure in a second parallel array that is interleaveably alignable with the first parallel array. Means for automatic control are provided for misaligning the second parallel array from the first parallel array to vary gap width between adjacent rollers. Each roller in the second parallel array may also be tapered to vary gap width as a function of roller length. Rollers may include helical ridges for urging objects along the gaps.

Abstract: A system automatically loads a bin with a filled deformable container such as a sack of produce being conveyed along horizontal rollers. A movable support structure has a coupling end attachable to a robotic arm, and a lifting end supporting a plurality of parallel rods. By means of the robotic arm and a programmable logic controller, the plurality of parallel rods can be positioned between and parallel to the horizontal rollers, raised when the container is conveyed to a loading position above the parallel rods, moved to a predetermined position above the bin, and rotated to allow the container to slide downward along the parallel rods and into the bin under force of gravity. The loading sequence can be repeated a number of times, changing the predetermined position each time to stack a plurality of the containers in a desired configuration such as overlapping rows of offset sacks.
