COSTS OF PRODUCING SUGAR BEETS 11 Aume covered with removable boards. As needed, the beets are carried into the factory from the bins by the swift current of the water in the flume. The process of manufacture consists of cleaning and slicing the beets, placing the slices in large cylinders and extracting the sugar by diffusion. This is 2ccomplished by successive treatments with hot water. The extract is clarified by treatment with suitable chemicals, the sludge-like precipitated material removed by filter- ing, and the clean juice evaporated under reduced pressure until a mass of sugar crystals has been formed. The sugar is finally sepa- rated from the molasses by centrifugals. After several strikes of sugar have been obtained, the molasses is further desugarized by other processes. From the centrifugal machine the sugar is sent to the driers, where excess moisture is removed by a current of warm air. The sugar is then ready to be sacked and sent to market. In Europe, where raw beet sugar is produced in many factories, the product is sent to a refinery for manufacture into the final product in much the same manner as raw cane sugar is refined in the United States, where (and to some extent in Germany) the beet-sugar fac- tories themselves turn out the final product. The principal by-products of beet-sugar manufacture are beet pulp, which may be fed to stock wet or may be dried for stock feed, and molasses, which is highly valued as a stock feed and for manu- facture into such products as alcohol, fusel oil, and vinegar.
