Application Of Activated Carbon In Edible Oil Refining

Application Of Activated Carbon In Edible Oil Refining
Powdered activated carbon can be made from a variety of carbonaceous raw materials such as coal, wood, husk, etc.. After high temperature treatment, and then activated with chemical activators such as phosphoric acid and zinc oxide, etc., or by air and steam activation to increase the surface area and adsorption activity. This powdered activated carbon is usually used together with activated clay to promote discoloration and purification of oils. powdered activated carbon water treatmentThe powder active charcoal can effectively remove the polycyclic aromatic hydrocarbons of the polymer which can’t be adsorbed by the clay. Active carbon has particularly strong adsorption effect on polycyclic aromatic hydrocarbons, even by pressing the activated carbon filter cake, the filtered oil does not contain polycyclic aromatic hydrocarbons.

Powdered activated carbon for decolorization of edible oil has very obvious characteristics compared to other activated carbon. For example, they are non-toxic and harmless, low ash content, strong adsorption capacity, high decolorization rate, high mechanical strength and easy regeneration. The specific characteristics are as follows:activated-carbon-pellets.com

1. Non-toxic, harmless, non-irritating gas. These decolorized industries are all foods and medicines that are closely related to us. Therefore, in order to ensure their safety, the powdered carbon active used for decolorization must be non-toxic, harmless and non-irritating.

2. Low ash. If the powder active carbon used for decolorization contains a large amount of ash, the ash will be added into the foods and medicines during the decolorization process, which will seriously affect the quality of foods and medicines.

3. High iodine value. The higher the iodine value, the stronger its adsorption capacity.

Food grade wood based powder activated carbon is suitable for decolorization of edible oil. The specification of activated carbon can be selected according to the type of edible oil and the production process requirements to achieve the best effect.
