1. the manufacture method of a coffee carbon dust comprises the following steps:

  • A, pre-carbonizing treatment;

    the coffee grounds that will brew dewaters after cold water cleans again, directly inserts drying in the pre-carbide furnace after having dewatered, and carries out pre-carbonization;

    Grease in B, the pre-carbonization coffee grounds of removal;

    the coffee grounds after the pre-carbonization is taken out,,, clean with clean water again after having soaked to remove the remaining grease of coffee with a certain proportion of one scheduled time of soda ash aqueous solution soaking;

    C, final pre-carbonization coffee grounds make coffee carbon;

    will remove coffee grounds behind the grease and insert one afterwards in the carbide furnace, the coffee grounds that makes this back carbide furnace will remove behind the grease is heated under 600~

    650 ℃

    of temperature dry, and make the most of carbonization of original organism, make the coffee grounds carbonization under anoxic and pyritous condition, this coffee grounds pyrolysis is formed the structure of many ceasmas property;

    The activation treatment of D, coffee carbon;

    when temperature does not descend as yet after the above-mentioned steps carbonization is finished, in carbide furnace after 850~

    950 ℃

    of importings of saturated vapo(u)r, carry out selective oxidation and make the activation of coffee carbon;

    The miniaturization of E, coffee carbon is ground;

    adopt wet type ball-type shredder that coffee carbon is ground to 0.1~

    20um size.
