As a result of harvesting an excessive amount of soil residue usually adheres to the crops and has to be removed by way of a suitable cleaning/washing technique. This falls under the responsibility of the HDS-L. The machine combines several processing steps: de-stoning, washing and water treatment. First, the adhering soil and stones are removed via upstreaming. A chain conveyor discharges the sediments over a chute.The water flow transports the sugar beets downstream into a washing drum. Here, the cleaning and drying takes place. A belt, that can be pivoted by 180 degrees at the rear end of the beet washer, finally discharges the prepared sugar beets. The built-in water treatment plant cleans the used water with the help of a lamella separator and feeds it back into the water cycle. This reduces the water requirement to a minimum. A screw-conveyor transports the sludge from the water treatment cycle to a pump sump, from where it is pumped into suitable containers or vehicles for removal. To cut a long story short: The HDS-L is the all-in solution for washing and cleaning and helps saving a lot of water and energy.
