beet sugar making and its chemical control

Book cover
PREFACE The aim of this work is to aid those who are starting their career in the beet-sugar manufacture but lack systematic training in the technique thereof. Having this in view, the author has en- deavored to explain not only the practical operations of sugar house stations but also the fundamental principles involved in the various processes of the sugar house and in the methods for analysis of various sugar house products. Especial attention of the reader is invited to Table IV which may be used to advantage by sugar house chemists in their control work as it dispenses with practically all the calculations pertaining to the determinations of sugar and purity of juices and Brix of undiluted thick syrups. In preparing this work, lowing references An Introduction to the Study of Chemistry, Theoretical Chemistry, Organic Chemistry, Analytical Chemistry, Organic Chemistry, the author has made use of the fol- Remsen.

Borson, who made the drawings for the illustrations in this book, and by Mr. R. S. Hiltner who reviewed the manuscript and made valuable suggestions. His gratitude is also due to Mr. Frederick Schlumbohm, who gave much important information on the process of sugar boiling. Owosso, Michigan, 1908. Y. N.
