Compositions and processes for clarification of sugar juices and syrups in sugar mills

摘要

This invention relates to compositions and processes for improving the clarification of sugar juices and syrups in sugar mills. The process involves adding compositions directly to the juice and or syrup. The compositions provided in this invention are mixed intimately into the sugar juices or syrups, and allowed sufficient time to react with the sugar juices or syrups as well as with the any other chemicals added in the clarification processes so as to impart an improvement in the purity of the clarified juice or syrup obtained therefrom. Compositions include at least one particulate sulfur reagent containing at least one sulfur atom and at least three oxygen atoms, and one or more particulate solids selected from the group consisting of (A) a silica reagent, (B) a particulate phosphorous reagent containing at least one phosphorous atom and at least three oxygen atoms in the chemical formula, (C) a particulate carbonaceous reagent, (D) a particulate aluminum reagent containing at least one aluminum atom and at least three oxygen atoms in the chemical formula, (E) a particulate filter aid, (F) a polymer decolorant, (G) a particulate ammonium reagent having at least one ammonium group (NH₄) in the chemical formula, and (H) a bleaching earth.
