Activated Bleaching Earth is created through the activation process of a specific type of clay such as Bentonite by the application of acid or heat in temperatures ranging from 200-250°C. This process causes the clay to expand, forming a complex and porous structure. These activated clay particles are then mixed with the oil to be purified, and heated at temperatures of up to 110°C. The polar impurities present in the oil are adsorbed onto the surface of the clay and the oil is then filtered to separate the clay particles along with other unwanted impurities, resulting in a cleaner and purer oil product.
BLEACHER bleaching earth derived from the natural clay mineral Bentonite has a purifying effect. It is formed by an acidic activation of Bentonite, which changes its special layered structure: the ion exchange with the protons enables additional water to enter between the layers and the mineral swells.
The surface area thereby increases fivefold. The activated and greatly enlarged surface can bind all undesired accompanying substances and impurities from the oil.
WITH BLEACHER YOU HAVE 4 KEY BENEFITS
Effective removal of chlorophyll, carotenes and Other coloring pigments
Quick easy settling and filtration results in less.Oil loss for the customer and higher through put.
Higher active surface area results in improved bleaching.Capacity using less quantity of clay .
Contains no mineral acids that can damage the oil.
