A new method for making an air-containing mixture introduces air into a viscous mass of raw mixture for forming the air-containing mixture. The introduction of air is performed in connection with introducing the mixture in a treating unit. The raw mixture is pumped under pressure through a nozzle for forming at least one jet which is sprayed through an air space against the surface of the mixture. Air is entrained in the jet of the mixture. The air-entraining jet enters the mixture, forming the air-containing mixture. The air-containing mixture formed thereby is subsequently introduced into the treatment unit.

1. A method for making an air-containing mixture, comprising: providing a supply source of a viscous mass of raw material,providing a nozzle for receiving and supplying the raw material from the supply source,providing a pump coupled to the supply source and the nozzle,providing a mixing tank,providing an air source,pumping the raw mixture under pressure through the nozzle into the mixing tank,introducing air into the viscous mass of the raw material after pumping the raw material into the mixing tank and forming the air-containing mixture,forming an air space above the air-containing mixture in the mixing tank,forming at least one mixing jet by the pumping of the raw material through the nozzle,spraying the at least one mixing jet in the air space against the surface of the air-containing mixture,mixing air with the at least one mixing jet into the air-containing mixture in the mixing tank below the air space,entraining the air in the air-containing mixture and forming a final air-containing mixture, andintroducing the final air-containing mixture into a treatment unit. 2. A method according to claim 1, wherein the viscous mass is an ice mixture, and the treatment unit is a freezer. 3. A method according to claim 1, wherein the formed jet is imparted such a speed that a foam of raw mixture and air is formed in the surface of the mixture in the region of impact. 4. A method according to claim 1, wherein there is maintained a largely constant jet speed across a range of flow rates as the nozzle is imparted a variable geometry. 5. A method according to claim 1, wherein a bundle of jets is formed which is sprayed against various points of the surface, while a substantial part of the surface is utilised for the introducing of air. 6. A method according to claim 1, wherein the jet is fan-shaped for forming an elongated impact area in the surface. 7. A method of making an air-containing mixture, comprising providing a mixing tank, partially filling the mixing tank with mixture, introducing the air into the viscous mass of raw material in connection with the introduction of the raw material in the treating unit by providing air in the mixing tank above the mixture, pumping the raw material under pressure through a nozzle into the mixing tank through the air above the mixture and forming a mixing jet, spraying the mixing jet through the air above the mixture and introducing the air into the mixture and spraying the mixing jet against a surface of the air-containing mixture for introducing air into the mixture and flowing the air containing mixture to the treatment unit, where the air is introduced into the viscous mass or raw mixture for forming the air-containing mixture, and where the introduction of air is performed in connection with the introducing the air containing mixture in a treating unit, where the mixing tank is provided between the pipe for introducing the mixture and the treatment unit, wherein the mixing tank is partly filled with the air-containing mixture, that in this mixing tank there are provided the air intake for supplying air to the mixing tank, the 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 providing an outlet from the mixing tank for the air-containing mixture for connection to the treatment unit. 8. The method according to claim 7, further comprising freezing the air-containing mixture in the treatment unit, which is an ice cream freezer. 9. The method according to claim 7, wherein the providing the nozzle further comprises providing a variable geometry nozzle and further comprising maintaining an approximately constant jet speed over a wide range of flow rates. 10. The method according to claim 7, wherein the providing the nozzle comprises providing a multiple nozzle forming a bundle of jets and further comprising directing the jets spraying against various points of the surface. 11. The method according to claim 7, wherein the providing the nozzle comprises providing a film forming nozzle producing a fan-shaped jet with an elongated impact area on the surface. 12. The method according to claim 7, further comprising providing a vessel or reservoir into which the mixing jet is spraying within the mixing tank. 13. The method according to claim 7, further comprising providing a bypass for flowing cleaning-in-place liquid at a high flow rate with low pressure drop into the mixing tank. 14. A method for making an air-containing mixture, comprising introducing air into a viscous mass of raw material for forming the air-containing mixture, and where the introduction of air is performed in connection with introducing the material in a treating unit, where the raw material under pressure is pumped through a nozzle, wherein by pumping the raw material through the nozzle, at least one mixing jet is formed which is sprayed through an air space against the surface of the air-containing mixture in a mixing step, so that air is entrained in the mixture and that the air-containing mixture formed thereby is subsequently introduced into the treatment unit, wherein a bundle of jets is formed which is sprayed against various points of the surface, while a substantial part of the surface is utilized for the introducing of air.
