The paper has the primary object of making known the application of electricity in the treatment of sugar beet through all the stages to the ultimate production of pure sugar. No claim is made by the author to have treated the subject in such a way that no more could be written; he has endeavoured to convey the idea of the main scheme of operation in the factory with which he is connected.It may be concluded that, although many factories in this country have applied electricity in the best manner possible within their limited expenditure, yet both in the factory and in the laboratory there still remains much room for further improvement. For instance, individual drives could be installed in many places where at present one large driving unit and line shafting now exist, and provided they are suitably interlocked—especially where elevators and conveyors work in conjunction—would prove a great advantage. Again, the sugar house should be equipped with the best type of sugar-spinning centrifugals. Much has been done by the manufacturers in conjunction with the users to improve this class of machinery.
