Quality & ComplianceQuality & Compliance
We are producing lot wise after, completion of one lot (10 mt) we maintain the following parameter.
Surface area measured the surface area to know the activation condition and expected adsorption capacity of product
Pore Volume Measured the pore volume to know the activation and washing position which directly related with product adsorption capacity, filtration, delta acidity (difference of total acidity and free acidity) and etc.
Bleachability After bleaching the neutral oil in laboratory and pilot refinery we checked both bleachabilty by lovebird tintometer and spectrophotometer and compare the result by our either our standard sample or party sample and effect in free fatty acid , soap ppm phosphorous content , and heavy metals reduction .
Residual Acidity we check the residual acidity and PH value to know the present percentage of free acid which is responsible for less bleachablity, colour reversion and increasing of peroxide value.
Moisture content We maintain the moisture content By AOCS (AMERICAN OIL AND CHEMIST SOCIETY) for customer less use of bleaching earth and high percentage of colour pigment reduction.
Filtration and oil retention – we chech the filtration and oil retention of product by AOCS Method which is directly related to production capacity of refinery and bleaching cost / refining loss of plant .
Particle size we maintain the standard average particle size, which is suitable for highest bleaching efficiency and filtration.
Bleaching Earth has found significant application in
- Decolourising by removing color pigments like carotenoids, chlorophyll, pheophytine.
- 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, anisidine 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.
Special Bleaching Earth for You!
We have expertise in the field of manufacturing Bleaching Earth, both by dry process and wet process.
Therefore, the advantageous position of offering you different grades from both dry or wet processes as well as by the
combination of both the processes.
This results in the selection of a very cost-effective and high-quality Bleaching Earth grade. A specific set of various grades will
be suggested on receiving the details of the application. Please feel free to contact us for any query, without any obligation.
