摘要： A process for producing refined sugar directly from plants of cane or beet raw juices which bypasses the traditional manufacturing of an intermediate product called "raw sugar". After treatment of the sugar juice with a flocculant, the juice has pressurized air dissolved in it, followed by rapid lowering of the pressure to ambient in a dissolved air flotation cell to separate impurities by aeration. Further amounts of flocculant are added, and the juice is passed through a serpentine flocculator comprising a pipe containing a plurality of relatively straight section interrupted by sharp bends to expose the juice sequentially to different turbulent regimes defined by different ranges of Reynolds numbers to form flocs containing undissolved solids. Flocs and other undissolved solids are separated from the juice by flotation and settling. The sugar juice or liquor is partially evaporated to a concentration between about 45.degree. and 50.degree. Brix to form a syrup, after which the syrup is again contacted with a flocculant. Following further treatment in the serpentine flocculator and dissolved air flotation cell, the remaining syrup is passed through filters such as silica sand, activated carbon and diatomaceous earth. The filtered syrup is contacted with ion exchange resins to decolorize and deash the syrup, and then it is evaporated to a concentration of 62.degree.-64.degree. Brix. Thereafter sugar is crystallized from the syrup.The apparatus for separating undissolved impurities by flotation and settling passes sugar liquor between an assembly of closely spaced plates having corrugations in a direction perpendicular to the direction of flow of the liquor. The plates are disposed at an angle so that settled impurities may slide to the bottom of the assembly.

摘要： The invention is a process for the removal of impurities comprising phenolics, dextrans or amino nitrogen from an aqueous saccharide solution. The solution is contacted with a sorbent, which itself is also an embodiment of the invention, comprising a cationic nitrogenous surfactant, the molecules of which contain at least one alkyl group of at least 8 carbon atoms, deposited on the surface of a microporous hydrophobic polymeric support. The deposition is accomplished by contacting a solution of the surfactant in an appropriate solvent with the support. The impurities are adsorbed onto the sorbent and the aqueous saccharide solution is removed from contact wiht the sorbent. The solvent must be completely miscible with the saccharide solution and the solution of the surfactant in the solvent must have a maximum sorbent wetting rate of at least 100 g/m.sup.2 .multidot.min., and a sorbent bed retention of at least 140%, based on the bed interstitial volume. The partitioning coefficient of the impurities in the surfactant asnd solvent deposited on the support, as compared to in water, must be at least 20.The process is extremely effective in removing impurities from saccharide solution shaving very high concentrations of impurities, and at very high flow rates.

摘要： A process for removing color, turbidity, flavor, and odor from impure, high Brix, sugar syrup involves entrapping the sugar impurities in an insoluble, primary calcium phosphate or aluminum hydroxide floc at about neutral pH, dividing the sugar syrup into a small portion and a large portion, aerating the small portion of the syrup at a specific Brix, recombining the small portion and the large portion, adding a polyelectrolyte to convert the primary floc into a secondary floc to which the air bubbles easily adhere and to cause flotation of said secondary floc, thus forming a scum mat at the top of the vessel. The purified sugar syrup is then filtered with or without activated carbon and small amounts of a filter aid to produce a sugar syrup with substantially reduced color, turbidity, flavor, and odor. The sugar in the scum is recovered by mixing it with water and allowing a second flotation to take place without any further aeration or chemicals addition.

Use of this admixture in place of bone char exclusively results in significantly improved decolorization. The GAC/BC admixture can be effectively reactivated at a temperature within the limit of 900.degree. F. to 1200.degree. F.
