  • Patent number: 10569195
    Abstract: Described herein is a method of adjusting the composition of a chromatography product to achieve a target enriched proportion of a desired component from an input feed having a lower proportion of the desired component using simulated moving bed (“SMB”) chromatography wherein the eluent for the SMB apparatus may comprise the very input feed being enriched. The method is exemplified by enriching a high fructose corn syrup from a 42% fructose syrup to a 55% fructose syrup without substantially reducing the dissolved solids concentration of the 55% syrup relative to the input 42% syrup. The 42% syrup is also used as the eluent for the SMB apparatus and may be reconstituted from the raffinate stream by passing the raffinate stream over a glucose isomerase column alone or in combination with a dextrose feed. The method reduces water usage and saves energy by minimizing the need for evaporation to obtain a 55% fructose syrup with a high dissolved solids content.

  • Publication number: 20090126719
    Abstract: A process for the treatment of sugar cane filter cake mud separates and extracts the mud's components into useful materials. The materials include fiber, lignin, beta-carotene, oil containing a high content of phytosterols, and refined wax. The fiber can be used as an animal feed or a source of energy, the refined wax is a resource of policosanol and other established purposes, and resin can be used an additive in asphalt mixtures and tire manufacturing or can be recycled back into the sugar milling process. The process is self contained, requiring the input only of fresh water and chemical additives to adjust pH and coloration.

  • Patent number: 7160394
    Abstract: An apparatus for the continuous process of raw mixed sugar juice clarification by means of the settlement of insoluble particles and juice precipitate in a cylindrical clarifier tank that permits non-turbulent vertical subsidation and short retention time of the sugar juice in a relatively large, non-turbulent settling sector of the contents of the cylindrical clarifier tank which is maintained by the continuous rotary advancement of the raw mixed sugar juice entry and clear sugar juice and precipitate extraction station arm that rotates within and around the center of the annular shaped cylindrical clarifier tank. The rotating arm has three internal radial compartments which provide for the introduction of raw mixed sugar juice and the extraction of clear sugar juice and precipitate, in and out of the annular clarifier tank in the immediate vicinity of the respective leading and trailing faces of the rotating arm, through adjustable slots on the leading and trailing faces of the arm.
