The cylinders of one set each penetrate the gaps between the cylinders of the other set, and each set of cylinders leaves a radial gap by reaching just short of the opposite base (either the floor 7 or the lid 3). At least some of the cylinders of the rotating set can be made at least partially of a woven material which can be fashioned like a sieve. On the static cylinders 4, vibration generators 19 and/or heating devices 13 may be installed (FIG. 1). ## Claims ### Claim 1 A centrifuge for gassing or degassing liquids comprising: a housing; a lid fixedly mounted to the housing; at least one stator fixedly mounted to the lid and depending downwardly therefrom; a shaft capable of rotation disposed in the housing; a floor mounted to the shaft end disposed beneath the stator; and at least one rotor having an inner face and an outer face mounted to the floor and extending upwardly therefrom such that the rotor is disposed adjacent to the stator. ### Claim 2 (depends on 1) The centrifuge of claim 1 further comprising a heating means operatively engaged to at least one stator for heating the stator. ### Claim 3 (depends on 2) The centrifuge of claim 2 wherein the heating means comprises an electrical resistance heater. ### Claim 4 (depends on 2) The centrifuge of claim 2 wherein at least one stator is double-walled and the heating means is disposed within the stator double wall. ### Claim 5 (depends on 1) The centrifuge of claim 1 further comprising a set of stators wherein the stators are coaxially arranged cylinders and further comprising a set of rotors wherein the rotors are coaxially arranged cylinders. ### Claim 6 (depends on 1) The centrifuge of claim 1 wherein the inner face of the rotor has a rough surface for retarding the flow of liquid. ### Claim 7 (depends on 1) The centrifuge of claim 1 wherein at least one rotor comprises a woven material which is, at least in part, liquid permeable such that the liquid to be gassed or degassed flows, at least in part, through the rotor. ### Claim 8 (depends on 1) The centrifuge of claim 1 wherein in at least one stator comprises a woven material which is, at least in part, liquid permeable such that the liquid to be gassed or degassed flows, at least in part, through the stator. ### Claim 9 (depends on 1) The centrifuge of claim 1 further comprising at least one vibrator operatively engaged to at least one stator for vibrating the stator. ### Claim 10 A centrifuge for gassing or degassing liquids comprising: a housing having a top and a bottom wherein the housing has at least one opening for the transmission of gas; a lid mounted on the housing; at least one top cylinder mounted to the lid and depending downwardly therefrom; a shaft disposed in the housing; a floor mounted to the shaft and disposed beneath the top cylinder; at least one rotor mounted to the floor and extending upwardly therefrom such that the rotor is disposed adjacent to the top cylinder; heating means operatively engaged to at least one top cylinder for heating the top cylinder; and a liquid supply pipe having an outlet for introducing liquid into the housing wherein the outlet is disposed within the rotor. ### Claim 11 (depends on 10) The centrifuge of claim 10 wherein the heating means comprises an electrical resistance heater. ### Claim 12 (depends on 10) The centrifuge of claim 10 wherein the top cylinder contains an inner chamber and the heating means comprises steam injected into the chamber. ### Claim 13 (depends on 10) The centrifuge of claim 10 wherein at least one rotor has a rough surface for retarding the flow of liquid. ### Claim 14 (depends on 10) The centrifuge of claim 10 wherein the rotor comprises a woven material which is, at least in part, liquid permeable such that liquid flows, at least in part, through the woven material. ### Claim 15 (depends on 10) The centrifuge of claim 10 further comprising a vibrating means operatively engaged to at least one top cylinder for vibrating the top cylinder. ### Claim 16 (depends on 15) The centrifuge of claim 15 wherein the vibrating means comprises an ultrasound generator. ### Claim 17 A method of degassing or gassing liquids in a housing having stators fixedly mounted to the housing and cylindrical rotors disposed adjacent to the stators comprising the steps of: introducing the liquid into the housing wherein the housing is at a controlled pressure; injecting the liquid into the center of the rotors; rotating the rotors with respect to the housing such that the liquid travels up a surface of the rotor and passes over the rotor to the adjacent stator, wherein the liquid then flows down to a floor, and up the next rotating rotor; retaining the stators in a fixed position with respect to the housing; and transporting the liquid out of the housing. ### Claim 18 (depends on 13) The method of claim 13, further comprising the step of heating the stators. ### Claim 19 (depends on 17) The method of claim 17 wherein the step of heating the stators comprises the step of injecting steam into a chamber in at least one stator.
