Cane Sugar Membrane Filtration (CMS-Series)

Normally raw cane sugar crystals obtained from the traditional process are colored and strongly aromatic because of the presence of many impurities. The use of a memebrane process seems to be an efficient method for removing the color substances and simplifying further refining.

The membrane process for producing sugar from cane includes the step of filtering a sucrose-containing feed juice, which has been obtained from macerated sugar cane, through a first ultrafiltration membrane that has a first molecular weight cutoff. This ultrafiltration step produces a first ultrafiltration permeate and a first ultrafiltration retentate.

The first ultrafiltration permeate is filtered through a second ultrafiltration membrane that has a second molecular weight cutoff that is lower than the first molecular weight cutoff. This second ultrafiltration step produces a second ultrafiltration permeate and a second ultrafitration retentate. The second ultrafiltration permeate is nanofiltration through a nanofiltration membrane, thereby producing a nanofiltration permeate and a nanofiltration retentate. The nanofiltration retentate has a higher concentration of sucrose on a dry solids basis than the feed juice in step, and can be used in evaporation and crystallization operations to produce crystals of white sugar. The process can optionally include ion exchange and/or electrodialysis purification steps, prior to or after the nanofiltration step. Recycle syrups can be treated with a chromatographic separator to remove excess invert, ash and color.

Membrane technology can be used in the production of sugar cane juice drinks,  original brown sugar; "Membrane - resin process package" can be used for production of refined sugar, high-quality sugar, primary sugar , raw sugar and  edible syrup which replaces the traditional one-step, two-step method in the process of liming, sedimentation,,plate-frame.

"Membrane resin process package" has unique advantages of clarified sugar cane juice, without muddy, without adding chemical reagents, effective interception of microorganisms,reduce energy consumption, short process, small footprint ,achieving CIP cleaning,good regeneration performance, long service life.


Continuous ion exchange technology is a completely innovative separation technology, which is based on the traditional fixed bed resin adsorption and ion exchange technology, combined with the continuous countercurrent system developed. Through continuous ion exchange, can make separation column in a process cycle to complete the adsorption, washing, regeneration, eluting.

The advantages of continuous ion exchange technology :

1.compact structure, less piping, small footprint

2. high resin utilization, can reduce the amount of 50% -70%

3. high product yield, concentration and purity, and stable

4.washing and chemical reagents consumption less, save 50% -70%

5. little waste emissions, greener

"Membrane - resin process package" advantages

1.can effectively filter clarified cane juice, the product is not muddy

2.without adding chemical reagents, reduce solid waste emissions
