Problems solved by technology

One aspect of this problem may be the limited amount or rate of production or supply of lime (15) to the sugar process steps
[0037] Another significant problem with conventional sugar processing systems can be the low purity of the sugar processing liquid (4), expressed as a percentage of sugar to the total dry solids of the sugar processing liquid (4)

Embodiment 1

[0101] The juice is obtained by traditional tower extraction of beets. Control and experimental groups were generated, each consisting of six equal portions of 500 mL of substantially identical infusion juice. Aliquots within the control and experimental groups were analyzed to determine the pH. The pH value of each aliquot of the extracted juice in the control group was about 6.3. Aliquots within the control group without any further treatment were titrated with 50% wt. / vol. caustic soda solution to an endpoint of 11.2 pH. Each aliquot within the experimental group was treated according to the invention, after which the pH of each aliquot was determined, and each experimental aliquot was titrated with 50% wt. / vol. caustic soda solution to End point at 11.2 pH.

[0102] The results are listed in Table 1 below. It can be understood from the table that the pH of each aliquot of juice before any treatment was about 6.3. After the treatment according to the invention of the e...

Embodiment 2

[0106] The juice is obtained by traditional tower extraction of beets. Control and experimental groups were generated, each consisting of five substantially identical 500 mL aliquots of the infusion juice. Aliquots within the control and experimental groups were analyzed to determine the pH. The pH value of each aliquot of the extracted juice in the control group was about 6.1. Aliquots within the control group without any further treatment were titrated with a 30 brix milk of lime solution to an endpoint of 11.2 pH. Each aliquot within the experimental group was treated according to the invention, after which the pH of each aliquot was determined, and each experimental aliquot was titrated to a pH of 11.2 with a 30 Brix milk of lime solution in substantially the same manner as the control group. end.

[0107] The results are listed in Table 2 below. It can be understood from the table that the pH of each aliquot of juice before any treatment was about 6.1. After the trea...

Embodiment 3

[0112] The juice is obtained by conventional tower leaching of beets and is treated according to the invention using the embodiment shown in Figures 12 and 13 with a position between the stirrer and the lime mixer. The leach juice is dispersed at a rate of approximately 100 cubic feet per minute into an atmospheric flow (upstream path 72 inches by 72 inches, counterflow path height approximately 144 inches) generated at a rate of approximately 400 cubic feet per minute. A variety of substances were transferred in the juice of , as identified by gas chromatography / mass spectrometry analysis shown in Tables 1 and 2 below.

[0113] table 3

[0114]

[0115] Table 3 shows the gas chromatographic analysis of samples SMBSC 1 and SMBSC 2 (condensates obtained from the gas stream after countercurrent exchange with juice as described herein), comparing the spectra of these samples with the organic compounds listed above 1-9. The gas chromatograms of the acid standard mixture sample...

Abstract

The present invention provides a sugar processing system for conditioning a sugar processing liquid obtained from plant material, the sugar processing system comprising an aeration chamber (37) and/or a vacuum chamber (42).

Description

[0001] This International Patent Cooperation Treaty patent application claims priority to US Provisional Patent Application Serial No. 60 / 457,516, filed March 24, 2003, which is incorporated herein by reference. technical field [0002] Generally, the present invention relates to a system for producing sugar from a sucrose-containing liquid obtained from plant material. In particular, the present invention relates to a sugar processing liquid regulator for altering the properties of a sugar processing liquid, and a sugar processing step for producing sugar using a sugar processing liquid having altered properties of the sugar processing liquid. Background technique [0003] Sucrose, C 12 h 22 o 11 , is a disaccharide, which is a condensation molecule linking a glucose monosaccharide and a fructose monosaccharide. Sucrose occurs naturally in many fruits and vegetables in the plant kingdom, such as sugar cane, sugar beet, sweet sorghum, sugar palm or sugar maple. The amoun...
