Every parameter of Bleach Master is tested in our in-house laboratory before dispatch. Here's what our numbers mean — and why they matter for your refining operation.
Each quality parameter is not arbitrary — it directly impacts your refining process economics. Here's what each one means.
Bleachability measures how effectively the earth removes colour from a standard rapeseed oil test. A higher percentage means darker oils can be refined to a lighter colour using less product — reducing dosage requirements and cost per tonne of oil processed.
Surface area determines adsorption capacity. Our acid activation process creates a network of pores in the clay, expanding surface area to 290-310 m²/g. Higher surface area means more binding sites for pigments and impurities — directly improving bleaching efficiency.
Oil retention is the % of oil that remains trapped in spent bleaching earth after filtration. At ≤20%, Bleach Master ensures at least 80% of absorbed oil is recovered. For a refinery processing 100 tonnes/day, even a 2% improvement in oil retention saves lakhs of rupees annually.
pH determines the acidity of the clay after activation. At pH 4.0, Bleach Master strikes the optimal balance — acidic enough for effective chlorophyll and carotenoid removal, but not so acidic that it breaks down oil quality or causes equipment corrosion. Critical for food-grade processing.
Each oil type has distinct bleaching challenges. Here's how Bleach Master addresses each one.
