Claim Text:
1. A device for aeration, comprising: a hermetically sealed reactor defining an interior space, said hermetically sealed reactor having a base at a bottom, a cover at a top and a side wall extending between said base and said cover; a rotatable stirring shaft arranged in said interior space and spaced apart from said side wall such that an interior reactor space is defined between a side surface of said stirring shaft and said side wall; projecting elements that project from said stirring shaft; at least one first gas feed channel arranged in connection with said stirring shaft and coupled to at least one of said projecting elements to enable gas to flow through said at least one first gas feed channel to said at least one projecting element; at least one second gas feed channel arranged in connection with said stirring shaft and separate from said at least one first gas feed channel; a gas feed system having a portion connected at a first end to said side surface of said stirring shaft and connected at a second, opposite end to said side wall of said hermetically sealed reactor, said portion of said gas feed system extending through said interior reactor space between said stirring shaft and said side wall, said gas feed system being coupled to said first and second gas feed channels to enable gas to flow through said gas feed system to said first and second gas feed channels; and a propulsion drive component arranged in said interior space of said hermetically sealed reactor for rotating said stirring shaft and thus said projecting elements projecting therefrom, said second gas feed channel being coupled to said drive component to enable gas to flow through said second gas feed channel to said drive component and thereby enable said drive component to rotate said stirring shaft when gas is directed out of said drive component; a shaft suspension or mounting arranged on said cover and rotatably retaining an upper end of said stirring shaft such that said stirring shaft operatively rotates relative to said shaft suspension or mounting while being retained by said shaft suspension or mounting; and a base mounting extending upward from a lower surface of said base into said interior space of said hermetically sealed reactor, a lower end of said stirring shaft being rotatably retained in said base mounting such that said stirring shaft operatively rotates relative to said base mounting while being retained in said base mounting, said stirring shaft being retained between said shaft suspension or mounting and said base mounting such that said stirring shaft is entirely in said interior space of said hermetically sealed reactor.
