Siederei, /. boilery, boiling room or house Sugar) refinery. 

Supply of MU water for a medium-pressure (450 psig) WT boiler, from a surface water source with very variable suspended solids and hardness (sugar refinery, South Africa). The process used is a. carbonate removal using hot-lime precipitation softening coupled with silica adsorption by magnesia addition b. clarification in anthracite filters and c. cation ion-exchange for the balance of hardness removal. 

NOTE Tannin chemistry has been used very successfully for many years in Africa and in Central and South America, in sugar refinery boilers operating at 650 psig and higher, without any measurable breakdown in performance or detectable contamination of steam from volatiles. 

This class of polysaccharide was well known in sugar refineries as the causative agent of ropiness it was formed from cane or beet sugar by bacteria of the Leuconostoc genus. Over many years, numerous papers were published, mainly with E. J. Bourne [Adv. Carbohydr. Chem. Biochem., 34 (1977) 1-22] and S. A. Barker as co-authors, describing the isolation, purification, properties, and structural features of dextrans. 

In sugar refinery control operations, pH electrodes should not be, as unfortunately they sometimes are, calibrated with standard buffer solutions, then placed on stream in sugar liquors, and assumed to read equivalent pH. Implicit in this operation is the equivalence of pH electrode response in dilute aqueous buffers at 24°C and in high Brix sugar solutions at elevated temperatures. Such equivalence does not exist. 

SUGAR REFINERY A processing facility in which nonsugar impurities are removed from raw sugar to produce a variety of sugar products. 

An extreme example of slime production is found in Leuconostoc dextranicum and L. mesenteroides where so much carbohydrate, called dextran, may be produced that the whole medium in which these cells are growing becomes almost gel-like. This phenomenon has caused pipe blockage in sugar refineries and is deliberately encouraged for the production of dextran as a blood substitute (Chapter 25). 

Rillieux s reputation as a young man with modern ideas must have reached Louisiana, however, because Edmund Forstall, a planter and banker in New Orleans, asked him to become the chief engineer of a sugar refinery under construction there. Forstall had already hired Norbert s cousin and brother, who were also young free men of color.

Edmund Oskar von Lippmann, 1857-1940. Austrian-German historian of chemistry and sugar chemist and technologist. Author of authoritative books on the chemistry and history of sugar, history of the magnetic needle, and history of alchemy and chemistry. Head of the large sugar refinery at Halle. Honorary professor of the history of chemistry at the University of Halle. See also ref. (87). 

Lactic acid is readily formed by the decomposition of beet root sugar in its juice, and some persons find mannite, although others are not able tc do so. A gummy substance is also produced, probably similar to that found in cane sugar refineries, when the sugar has been too long boiled and worked with.
