Decolourising Earth production process, appearance introduction, advantages and application performance

Appearance: white or light coloured fine powders

Product features

1, have a wide range of decolorization, adsorption and purification capacity, strong stability in application. Have a strong adsorption of pigments and impurities, the decolor pigments in plant oil rate of more than 95%.

Decolourising Earth

2, the use of this product is simple, no need to change the original production process of oil production enterprises. Oil acid value and decoloring and low, not rise, saves the dehydration process.

The cake 3, filtered (vegetable oil, animal fat) can be renewable, no pollution to the environment.

Process conditions when using

Decolorization temperature: 115 ~ 120 ℃ decolorization time: 20 ~ 30 minutes product index

The decolorization rate: 85 ~ 90% (AOCS): < 0.2% free acid

Moisture: < 10% fine degree: -200 >90%

The main properties of activated bleaching earth:

Activated bleaching earth mainly white and pink, odorless and tasteless, non-toxic, good activity, strong adsorption, easy to absorb moisture in the air, such as placing too long or moisture will reduce its adsorption function, the use of appropriate heating (80 to 100 degrees) resurrection, if heated to 300 degrees above began to lose crystallization water, structure change, affecting decolorization.

Selective adsorption ability, the decolorization rate high, with a low rate of oil, filtration speed, add less.

Effectively remove grease total phospholipid, soap and trace metal ions, is a natural antioxidant.

Removal of oil in aflatoxin, pesticide residues and other toxins and odor.

Acid number after bleaching not rise, do not back color, clear and transparent, stable quality, long shelf life.

Refining production is especially suitable for mineral oil, vegetable oil, animal oil.

Decolourising Earth  application:

Is a world rare mixed clay (natural attapulgite clay minerals and smectite symbiotic) as the main raw materials, through special processing technology made. This kind of Decolourising Earth minerals is the natural growth of mineral interwoven material, make the products have natural decolorization, adsorption properties. Through deep processing method makes these unique properties have the greatest degree of play and use.

Decolourising Earth can be widely used in Edible Rapeseed oil, soybean oil, peanut oil, cottonseed oil, corn oil, sesame oil, coconut oil, palm oil, sunflower seed oil and non edible oil (industrial) dynamic adsorption decolorization and plant oils; also used in petroleum products (Run Hua oil, paraffin, Vaseline). Decolorization and purification; decolorization can also be used for natural alkali purification, industrial waste oil recycling, decolorization and adsorption of carbonless copy paper color and monosodium glutamate, beverage, glucose, vitamin, silkworm chrysalis oil.


Better application effect in physical decolorization process.

Adsorption and decoloration soil all use double packing bag, standard weight per package for package of 25 kg, 40 kg, 50 kg of other weight, also can according to customer requirements and.
