Abstract
Abstract In a process for sterilization and homogenization of a liquid or fluid, these operations are carried out by subjecting the liquid or fluid to ultrasonic frequency vibrations for a predetermined period of time. In the device for carrying out the process, the liquid taken in from tank (10) is sent by a pump to a pipe length, inside of which or in proximity to which is arranged a sonotrode (5) connected to a converter-generator (14). As it travels through this pipe length, the liquid is subjected to vibrations and is sterilized or homogenized.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
41 words
Process for the sterilization and homogenization of a liquid or a fluid of low or medium viscosity, characterized in that the sterilization and homogenization are obtained by subjecting said liquid or fluid to high-frequency vibrations for a predetermined period of time.
Claim 2
Dependent Claim
88 words
Device for the sterilization and homogenization of a liquid or a fluid of low or medium viscosity according to the process in claim 1, comprising pumping means (11) suitable for taking in liquid or fluid from tank (10) and sending it through pipe length (1) in which, while traversing said pipe length, said fluid is subjected to vibrations produced by high-frequency vibration generating unit (5) installed inside of or in proximity to said pipe length (1), with the liquid or fluid then continuing on towards a collection container.
Claim 3
Dependent Claim
43 words
Device according to claim 2, wherein this pipe length forms chamber (1) equipped with inlet pipe (2) and outlet pipe (3) for the liquid or fluid circulating therein, inside of which sonotrode (5) is arranged coaxially, connected to a high-frequency vibration converter-generator (14).
Claim 4
Dependent Claim
62 words
Device according to claim 3, wherein inlet pipe (2) for the fluid or liquid has a longitudinal axis arranged on the extension of the longitudinal axis of the sonotrode, and discharges facing the terminal part (5'), independent of the latter, while said outlet pipe (3) discharges from said chamber (1) into an area close to the central part of said sonotrode (5).
Claim 5
Dependent Claim
24 words
Device according to claim 4, wherein around at least one part of said chamber (1) there is annular cooling jacket (7) for circulating fluid.
Claim 6
Dependent Claim
28 words
Device according to one of claims 4 or 5, wherein said chamber (1) also has overflow discharge (6) which returns excess liquid or fluid to said tank (10).
Claim 7
Dependent Claim
48 words
Device according to claim 2, wherein said pipe length (1) is surrounded on the outside by an annular member which contains a fluid that is made to vibrate by a ultrasonic frequency generating unit, with the fluid transmitting the vibrations through the annular member to said pipe length.
Claim 8
Dependent Claim
43 words
Device according to claim 2, wherein said vibration generator unit is sonotrode (65) whose terminal part is traversed by one or more channels (68i) flowing out into said pipe length (61) through which inert gas is caused to flow at a predetermined pressure.
Claim 9
Dependent Claim
64 words
Device according to claim 2, wherein said pipe length consists of a bundle of parallel tubes (71) traversed by the fluid to be treated, and the vibration generator unit is a sonotrode (75), facing the terminal part of which are mounted one or more lenses (72) which are able to concentrate ultrasonic waves from sonotrode (75), focusing them on tubes (71) composing this bundle.
Claim 10
Dependent Claim
34 words
Device according to claim 9, wherein said lenses (72) are attached to base (73) which is able to transfer the waves by varying the focal distance of the lenses with respect to sonotrode (75).
Claim 11
Dependent Claim
37 words
Device according to any of claims 3 through 10, wherein the sonotrode is made of metal and its terminal part is treated, using ion implantation, with a chemical element different from the metal which composes the sonotrode.
Claim 12
Dependent Claim
29 words
Device according to any of claims 2 through 11, also containing a filtering element located downstream of the pipe length in which the liquid is subjected to ultrasonic vibrations.
