PRE-BLEACH 300 is Activated Natural mineral product produced from natural minerals Magnesium Aluminum Silicates; it’s available in form of creamy white powder. It is used to remove soaps, phospholipids and trace metals from edible oil.
Pure silica/ Soap Adsorbent specially developed for selectively remove polar impurities soap, Phosphorous metal content from water degummed oil.
We have removed all leachable metal ions & metal oxides from raw clay use as starting material hence does not impart any adverse effect to cooking oil
Thermal activation done to increase surface area of product for better adsorption of impurity
Tightly controlled particle size distribution hence efficient filtration
Dosage 0.1% i.e. 1Kg/ Tons subject to gums present in oil
Recommended for use in caustic refining of vegetable oil such as Soybean Sunflower canola offers selective removals of Phospholipids
Prebleach 300 can also reduced cost by simplifying the neutralization step of edible oil refining process & helping to minimize environmental footprint
Positive impacts on sustainability are achieved by reducing water needed for washing process in centrifuge and reduce dosage of bleaching earth.

PRE-BLEACH 300 is soap adsorbent for the refining of all animal and vegetable Oils. It can be used in the following adsorptive operations.
As a refining or bleaching aid for the removal of phospholipids and fatty acid neutralization soaps in both caustic and physical edible oil refining process. It can replace the “Washing” step in the caustic refining process.
PREBLEACH 300 should be mixed with outlet oil of soap stock centrifuge at temperature between 85 to 95*C.
Slurry tank Residence time 25 min with agitation
Recommended oil moisture 0.2 to 0.3 %
Prebleach -300 can reduce dosage of bleaching earth in refining process by greatly reducing contaminant load on Bleaching Earth
Reduction in bleaching clay up to 20% when using prefiltration process before bleaching.
Prebleach 300 use to eliminate water washing process hence we can save power cost & steam cost associate with centrifuge and Hot water
No water washing can save 10% of hot water cost and effluent treatment cost associated with wash water
Saving in neutral oil loss associate with wash water
