The beet yard operation comprises the handling of sugar beets after they are received on site up to the beet hopper. It is not intended here to present a detailed description of all the individual steps involved, but rather to focus on the main technological objectives of the beet yard operation: sufficient removal of soil from the beets while limiting the associated (unavoidable) sugar loss as much as possible.
Parameters considered are:
– Washing requirements for beets from heavy (clay) soil versus beets with easy to remove light (sandy) soil;
– On site beet storage, as well as dry or wet beet intake;
– Sugar losses in different steps of beet washing and impact of retention time;
– Residual soil adhering to the beets after washing and HCl-insoluble ash in pulp.
