DTS supplies a range of buffer and bin systems for storing whole potatoes underwater. The outfeed of the buffer is designed with a horizontal discharge screw at the bottom of the auger and a vertical discharge screw to feed the next unit operation. Thanks to this design, these buffers ensure real first-in-first-out product buffering, and uniform outfeed from an uneven or discontinuous infeed. Alternative versions include pumped outlets, inclined dosing bunker with dry or wet hopper, and the bottom screw with various custom designs.
