CynerSorb

CynerSorb® For improved edible oil refining

  • Increases filtration capacity
  • Reduces oil losses
  • Eliminates or reduces bleaching earth dosing rates
  • Lowers refining costs
  • Reduces spent filter cake

CynerSorb® is a surface-engineered diatomite absorbent designed to replace silica gels and magnesium silicates in edible oil refining, simplifying the process and reducing spent filter cake and oil loss.

 

Two-in-one solution

Edible oils often contain soaps/phospholipids, glycerol and trace metals that need to be removed as part of the refining process. Typically this is done during the filtration stage using asynthetic amorphous silica gel or a magnesium silicate.

Silica gels and magnesium silicates have excellent adsorption characteristics but are very poor filter aids causing premature filter blockage and reduced refining capacity. Often, a diatomite filter aid is added to compensate and to keep the filter bed ‘open’. While this achieves the required increase in filtration capacity, it also adds process complexity and results in additional spent filter cake and associated oil loss.

CynerSorb® utilizes a diatomite filter aid base - meaning it has all the filtration characteristics of a diatomite. Our engineers have successfully surface-engineered the individual diatomite particles so they provide the necessary adsorption functionality.

As a result, CynerSorb can be used as a two-in-one solution fulfilling both the absorption and filtration functions.

Improved bleaching earth performance

CynerSorb® can also be used to eliminate bleaching earth where no color removal is required, or to significantly reduce dosing rates where some bleaching is necessary.

While working with partners in the edible oil industry, we have demonstrated that CynerSorb® makes bleaching earths more effective at removing color pigments, resulting in lower bleaching earth dosing rates. Apart from increasing refining capacity, this translates into less spent filter cake and therefore lower ester/oil losses.
