Customised Integrated Solution

Sugar Industry

The increased demand for sugar pushes sugar manufacturers to innovate on the production process. Suntar developed a series of membrane separations with moving bed system for sugar production which are highly recognized by the sugar manufacturers.

  • Filter the saccharification liquid with membrane to improve filtrate quality and reduce filter aid consumption
  • Apply ion-exchange moving bed for deashing which reduces resin and unit consumption
  • Concentrate and remove impurities with nanofiltration achieving higher product quality
  • Industrial chromatography separates sucrose and glucose
  • Apply membrane separation technology for water recovery

Glucose

01

APPLICATION

Membrane and continuous moving bed system increase product quality with lower production cost. The system is fully automated with all day operation to ensure stable high production.
Membrane filtration to remove impurities in the saccharification liquid resulting in high quality filtrate which reduces subsequent resin pollution and the problem of saccharification liquid colour reversion.
Continuous ion-exchange moving bed deashing reduces resin consumption by over 70%, reduces regenerant and water consumption by over 50% and reduces over 60% wastewater discharge.
Nanofiltration purifies saccharification liquid resulting in high glucose purity in one step.

Fructose

01

APPLICATION

Suntar’s unique nanofiltration technology further perifies glucose / fructose from 96% to over 99.5%. Filtrate can be used directly for high purity glucose or fructose syrup production.

Customised Integrated Solution

Sugar Alcohol

Suntar has applied membranes and continuous moving beds to the production of xylitol, erythritol, sorbitol, etc. and has developed a biological fermentation method for the extraction process of xylitol.

  • Ceramic membrane clarifies fermentation broth achieving higher filtrate quality while reducing resin pollution and bacteria recovery in the subsequent processes.
  • Ultrafiltration to remove protein, pigment and improve quality.
  • Nanofiltration concentrate sugar alcohol which improves crystal recovery.
  • Continuous moving bed reduces resin consumption and unit consumption.
  • Chromatography improves resin utility and product recovery.
01

APPLICATION

Ceramic membrane filters erythritol fermentation broth achieving high quality filtrate.
Nanofiltration removes impurities such as solube marcromolecular substances and pigments.
Simulated moving bed removes ash from erythritol, and reduces chemical and water consumption.
