Activated carbon for wine

Specifications

Activated carbon for wine;
1: methylene blue: 300mg/g
2. method: phosphoric acid
3. fe: 200ppm

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 10

 

4.Adding the food grade Phosphoric acid solution and catalyst to the dried sawdust to soak for 30 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 30 minutes, and 48 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

 

9.Testing the semi product (testing the product every 30 minutes, and 48 times a day)

 

10.Drying and crushing (water and particles control)

 

11.Packing the product.

 

3. Advantage:

 

1). One of the supplier for Norit.

 

2). High methylene blue: 300mg/g

 

3). High adsorption of caramel: 140%

 

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 200ppm

 

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