Introduction To Bleaching Technology

The Continuous Bleaching Process is carried out to remove colour pigments, residual phosphates, metals, soaps and oxidation products. Using bleaching earth and activated carbon as per requirement of process, bleaching process is carried out in two stages in a continuous manner.

In the first stage, Oil is heated at 100 – 110 Celsius and mixed with bleaching earth and kept at suitable temperature then it will with bleaching earth with mild agitation by specially designed turbine blades Agitator System under vacuum.

Oil is sprayed through specially designed nozzles mixed with bleaching earth and sufficient retention time is given to attain maximum possible bleaching of oil. By spraying oil, moisture is removed in the vessel itself.

In second stage oil slurry is pumped to a set of vertical pressure leaf filters where. Two filters are used alternatively to remove oil from bleaching earth and cake is discharged through bottom actuated butterfly valve. After filtration oil is circulated through candle type polish filters to further polish the oil remove any traces of particles.
