Bleaching Earth
ACTIVE-BLEACH is activated contact clay produced from natural occurring Montmorrilonite (Alumino silicate). With a layered a distinctive platelet likes structure. Acid activated bleaching is clay which chemically activated Smectite with mineral acid to produce high porous Alumino silicate with increased absorption properties. The bleaching clay is used to refine edible oils, fats mineral oils and hydrocarbons. It processed in an extremely controlled condition processed to give final product with purity and integrity.
Advantages of OM ACTIVE-Bleach
- ACTIVE-BLEACH has got excellent filter properties and least oil retention due to its unique particle size distribution and surface area. Decolorizing by removing color pigments like carotenoids, chlorophyll, and pheophytine.
- Effective color reduction because of its high activity and surface area.
- Significant chlorophyll reduction.
- Minimize rise of free fatty acid during bleaching and Deodorization due to very low mineral acid content in the clay.
- Fast filtartion rate & law oil retention.
- Filtration of high quantities of oil without choking the filters and the filtration being done in less reasonable time. Under normal filter conditions, it achieves excellent filtration results in less time and with minimum oil retention losses.
- Economy to its user with the usage in low quantities fast filterability and low oil retention losses.
- Removal of gums (phospholipids), FFA and soap contents and traces of heavy metals in vegetable oils.
- Reducing and controlling different oil parameters like peroxide value, anis dine value, uv-absorption value, FFA contents etc.
- Purification of aromatic compounds in case of mineral oils & waxes and removal of sulfur, acid – tars, acid – sludge, sulfonic acid etc.
Applications of OM INDUSTRIES ACTIVE-Bleach
- Refining of Vegetable oils like:
Cottonseed, Soybean, Sunflower, Rapeseed, Mustard, Peanut, Coconut, Corn, Olive, Rice bran, Palm, Palm-kernel, Linseed, Castor, Jojoba & Canola oils. - Refining of hydrogenated vanaspati Ghee oils.
- Refining of Mineral Oils like:
paraffin and waxes, insulating oil, rolling oil, white oil ,waste oil (lubricating oil), industrial triglycerides and fatty acids used for paints, varnishes and soaps. - Other applications like:
Solvents (for dry cleaning),bleaching of sulphur, effluent treatment plants.
Key Parameters of ACTIVE Bleach
- Bleaching efficiency
High bleaching efficiency lowers bleaching costs. ACTIVE-BLEACH provides high bleaching efficiency that increases surface area. Fatty Acid Content The presence of very low mineral acid content in ACTIVE-BLEACH reduces the likelihood of increase in free fatty acid content during bleaching and deodourisation. Significant Chlorophyll Reduction. Small amount of ACTIVE-BLEACH is adequate to reduce chlorophyll levels significantly. - Filterability & Oil Retention
Optimum filterability requires particles of uniform size. ACTIVE-BLEACH has been developed to filter high quantities of oil without chocking the filters. It enables speedy process even under normal operational conditions. With care taken in respect of the particle size distribution and product density, ACTIVE-BLEACH minimizes oil retention; thus reducing processing cost.
