Supply wood based powder for food grade activated carbon

Product specification:

Supply wood based powder for food grade activated carbon can be made to any grade of absorb ability, discolor ability, any sieve per customer's requirement. It's high rate of absorption, strong ability of discoloring help to speed the refine, catalyze and coagulate effect. It reduces user's construction and maintaining cost effectively. Powdered AC is widely used in water plant, food and medicine industry.

Uses:

Mainly used in many kinds of air cleaner, air-conditioner air condition fan, computers monitor, lampblack purification and so on. It also can be used in living domain, such as making activated carbon shoe pad, health care mattress, pillow core, the refrigerator and so on, and has good deodorizing effect. It is designed for the removal of objectionable tastes, chlorine, unpleasant odor, color spore, lead, and microorganisms. At the same time, it keeps high flow.

Advantage:

1). One of the supplier for Norit.

2). High methylene blue: **0mg/g min

3). High adsorption of caramel: **0%

4). Food grade: using the food grade phosphoric acid which has been passed the certificate of EU food grade.

5). Low metal content: Fe content is lower than **0ppm

6). Low ash: ash content is lower than 3% as per the raw material of China Fir.

Production process

1.Choosing the wood chips or sawdust from China fir as raw material 
2.Sieving the raw material from wood sawdust to be sure the material is without pollution from the Purifying Device which is imported from Switzerland 
3.Drying the sawdust in the Drying Equipment to control the moisture be around *0 
4.Adding the food grade Phosphoric acid solution and catalyst to the dried sawdust to soak for *0 mins 
5.Carbonized the   wood sawdust which is with phosphoric acid in the rotary under high temperature, during the activation, the carbon molecular structure is changing so that the hole space and the specific surface area will be bigger 
6.Testing the semi product (testing the product every *0 minutes, and *8 times a day) 
7.Acid washing( washing the phosphoric acid and impurities to be divided from the carbon 
8.Water washing (3 times by boiling water, 2 times by cooling water.
