Abstract:
1. An apparatus comprising a closed mixing tank for holding a viscous raw mixture partially filling the tank, an air intake for introducing air into the tank above the viscous raw mixture, and a nozzle in a top of the tank for discharging under pressure the viscous raw mixture into the tank through the air in the tank and entraining the air and impacting the viscous raw mixture in the tank and introducing the entrained air into the viscous raw mixture within the tank for making an air-containing mixture, where air is introduced into the viscous mass of raw mixture for forming the air-containing mixture, and where the introduction of air is performed in connection with introducing the air-containing mixture in a treating unit, where the mixing tank is provided between a pipe connected to the nozzle for introducing the mixture and the treatment unit through which the air-containing mixture is removed from the tank, wherein the mixing tank is partly filled with the formed air-containing mixture, that in this mixing tank there are provided an air intake for supplying air to the mixing tank, a nozzle for pumping the raw mixture in under pressure for forming at least one mixing jet which through an air gap is sprayed against the surface of the air-containing mixture in the mixing tank, and an outlet for air-containing mixture for connection to the treatment unit.
