This invention relates to electromechanically assisted and/or “ultra” sonically assisted acceleration of fermentation and/or maturation. More particularly, it relates to specialized electromechanical devices and systems for mechanical and/or ultrasonic/sonic agitation of fermenting or maturing liquids and stimulation thereof.
Neel et al. (Neel, P., Gedanken, A., Schwarz, R., Sendersky, E., “Mild Sonication Accelerates Ethanol Production by Yeast Fermentation”, Energy & Fuels, 2012, 26, 2352-2356) demonstrated accelerated fermentation time rates by a factor of 2.5 using brewer's yeast (Saccharomyces cerevisiae) when a flask of glucose solution was agitated in a conventional ultrasonic cleaning bath. Matsuura et al. (Matsuura, K., Hirotsune, M., Nunokawa, Y., Satoh, M., Honda, K., Acceleration of Cell Growth and Ester Formation by Ultrasonic Wave Irradiation, Journal of Fermentation and Bioengineering, 1994, 77, 1, 36-40) demonstrated reduced fermentation times by up to 60% for flasks of beer, wine and sake solutions in contact with a piezoelectric element.
These results demonstrate the viability of sonic fermentation, but do so only in a specially controlled laboratory environment. While Tyler, III et al. (U.S. Pat. No. 7,063,867), Dudar et al. (U.S. Pat. No. 4,210,676), and Leonhardt et al. (U.S. Pat. No. 7,220,439) have attempted to extend these principles to commercial applications, the methods/devices of the prior art have not been well adapted by commercial wine/spirits producers due to the clear difficulty of implementation. Accordingly, there has been a long-standing need in the wine and spirits community (as well as other fermentation/aging based industries) for easily implemented ultrasonic/sonic systems for commercial applications. Details of such and other methods and systems are provided in the below description.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

For the purposes of explicit disclosure, ultrasonic agitation by other researchers have been successful when using 40 kHz, 30 W/L and 43 kHz, 30 mW/cm2, 590 mW/L. Other researchers have shown 20 kHz and 1.6 MHz frequencies to be successful for accelerating the aging characteristics of rice wine. Accelerating the “ripening” alcoholic spirits in wooden barrels has been demonstrated for 20-50 kHz, 1.7 W/l, average ultrasonic intensity of about 0.5 W/cm2. Cavitation of wine for accelerated aging has been demonstrated by sweeping high-energy ultrasound 40 kHz-80 kHz.
Other possible successful frequency ranges and power levels and durations are dependent on the medium type, the target material dilution in the medium and objective for ultrasonic agitation, as detailed in the incorporated documents above.
For the purposes of ease of explanation, the term “electromechanical” will be defined herein to generally describe any device or system that performs mechanical work in response to an electrical stimulus, whereas the term “sonic” encompasses the term “ultrasonic” (ultrasonic being a segment of the sonic spectrum), and thereby may be loosely interchangable within this disclosure to describe mechanical displacement that has a vibrational frequency.
To realize the benefits of electromechanical agitation for the acceleration of fermentation or maturation of liquid for aging purposes, at a larger scale, be it for home brewers (for example, 3-20 gallons) up to industrial brewers, vintners and distillers (for example, 20 gallons to >320 gallons), a number of designs are described for imparting electromechanical assisted accelerated fermentation and/or maturation.
The following FIGS. illustrate various possible implementation modes for an electromechanical energy emitter (EEE) system that can be utilized with, for example, glass fermenters (e.g., carboys), wooden body fermenters (e.g., barrels, hogsheads, puncheons) or plastic fermenters/tanks due to the electromagnetic permeability of such containers. In an immersion device configuration of an embodiment of the EEE system, the system can be applied to any container that does not significantly interfere with electromagnetic waves (e.g., plastic, rubber, silicone, fiberglass, etc.). In other embodiments, the EEE system is re-configured to operate within containers known to interfere with electromagnetic waves.
The EEE system increases the speed of cellular growth and multiplication by means of “ultrasonically” generated waves that, in some embodiments, can have its frequency and intensity matched to the target application. The EEE system also increases the maturation of fermented liquids in wooden containers by homogenizing the wood extracts within the maturing medium, thereby continually driving a diffusion gradient at the wood/medium interface while also applying a push/pull action at the interface. By way of implication, this process extends to other containers in which wood alternatives in the forms of chips, spirals, dust, or the like, are utilized for the purposes of imparting wood-based maturation characteristics, or even non-wood based characteristics (e.g., packets of chemicals or organic materials, etc.).
The EEE system can be deployed using different architectures. The first architecture is by direct immersion of “independent,” displaced, self-contained, mechanical energy generating devices in the target medium. The immersion devices irradiate the medium and its holding container with electromechanical energy in the form of mechanical “sound” waves. These immersion devices can take several forms such as spheres, cubes, cylinders or any other geometric shape, the determination of which being based on application preference and design objective. For example, a cube-shaped immersion device will render it less immovable within the medium, while a sphere-shaped immersion device may roll around. While an egg-shape will provide other movement options. Also, in some embodiments, the immersion devices can present negative, neutral or positive buoyancy, or change their buoyancy depending on the conditions of the medium. This change of buoyancy can be active or passive, and can be utilized to optimize the delivery of electromechanical energy to the medium (e.g., move within medium), and/or improve energy transfer from an external power source, and/or indicate the level of alcohol in the medium (e.g., as a specific gravity indicator when the buoyancy is changed).
An optional “hook” 115 is shown provided at the top (or any side) of immersion device 100, so as to allow a user to easily retrieve the immersion device 100 within a medium. Of course, in some embodiments, rather than a hook 115 that is externally attached to shell 110, a magnet or even metal section (being responsive to a nearby magnetic “stick”) could be attached to shell 110 to help facilitate the retrieval of the immersion device 100. Of course, it is apparent that alternative methods or mechanisms for “grabbing” the immersion device 100 can be used without departing from the spirit and scope of this disclosure.
Interior to shell 110 is a primary electronics board 120 for the primary modules, non-limiting examples being power and communications electronics, and so forth. Secondary board 130 is provided for housing electronics for the transducer 150 and (optional) sensor 155. Transducer 150 may be directly attached to primary board 120 or displaced from primary board 120, being energized by line 152. The transducer 150 is a electromechanical device that imparts a mechanical vibrational energy, whether periodically or aperiodically. Non-limiting examples are a “cell-phone” vibrator, piezoelectric transducer, mechanical actuator, acoustic resonator, etc.
The transducer 150, when activated, provides the vibrational energy to the shell 110, which is imparted to the liquid or constituent medium that the immersion device is submerged in. Therefore, the immersion device 100 operates (as will be further explained below) as an independent vibrating source within the medium that does not require a physical “access portal” for power. Conventional “vibrating” systems require some access external power via a portal or port, thereby exposing the contents of the container to external gases, bacteria, and contamination. By use of an exemplary system that does not require external “access,” these concerns can be obviated.
Returning to
While two boards 120, 130 are shown, it is understood that in some embodiments, less boards or more boards may be used, according to design preference. For example, if all of the electronics could be housed only on primary board 120, then secondary board 130 may not be necessary, or vice versus. Accordingly, while this description is in the context of two boards, any number of boards that are suitable can be used.
Also, while
In some embodiments, transducer(s) 150 (and/or sensor 155) may be located on primary board 120 due to primary board 120 physical contact with shell 110, resulting in a higher mechanical efficiency of translating the transducer 150 motion to the body of shell 110. Alternatively, the transducer(s) 150 (and/or sensor 155) can be on secondary board 130, but with the transducer 150 in contact with the body of shell 110, resulting in a higher mechanical efficiency of translating the transducer 150 motion to the body of shell 110. Accordingly, output efficiency can be increased by appropriately moving the location of the transducer 150 within shell 110 or by facilitating some means of “contact” 160 between the transducer 150 and the body of shell 110 (e.g., glue, epoxy, gel, etc., that bonds or mechanically communicates energy from the transducer 150 to the body of shell 110). Therefore, the location, orientation, shape of any board or element/device/module inside shell 110 may vary. Thus, modifications, changes that are within the purview of one of ordinary skill in the art may be made without departing from the spirit and scope of this disclosure.
For example, the sensor 155 may
Power module for the boards can comprise induction coil 140 (illustrated here in exaggerated form) that absorbs transmitted energy from an external to the container transmitter (not shown), or a power storage medium 127 (located on primary board 120 or secondary board 130) such as battery, supercapacitor, or both, or other equivalent functioning device. With use of a power storage medium 127, pulsing or other modes of operation can be more easily achieved. Further, if power in the transmitter is temporarily disconnected, the electronics of the immersion device 100 can still function off of the power storage medium 127. The induction coil 140 may be located at the bottom of the shell 110's interior, and may be integrated into board 120, 130. In some embodiments, several induction coils 140 may be situated interior to the shell 110. In other embodiments, the induction coil 140 may be embedded in an “exterior” of the shell 110.
Presuming immersion device 100 is resting on the floor of a container, increased radiation efficiency can be obtained by locating transducer 150 away from the bottom of shell 110, radiating upward through the container. Of course, in some embodiments, it may be desirable to radiate in a different direction and therefore transducer 150 may be so oriented. Further, multiple transducers 150 may be utilized, arranged at different section/angles in shell 110, for different radiating patterns/directions. In more sophisticated embodiments, an array of transducers 150 can be formed to generate beam forming, allowing energy to be steered. In alternative embodiments, transducer 150 can be used for communication, sending, for example, sonic communication signals.
It should be apparent that as transducer(s) 150 are attached to the interior of the shell 110, when the transducer(s) 150 operate, it will vibrate the body of the shell 110. The shell 110 having a larger volume than the transducer(s) 150 will operate to “amplify” the motion of the transducer(s) 150. Accordingly, the entire shell 110 will vibrate in near phase sync with the transducer(s) 150 or out of phase sync (depending on coupling response and other mechanical parameters). In some embodiments it may be desirable to limit the vibration to only a portion of the shell 110, whereas the shell-to-transducer material may be flexible to act as a vibrating membrane, as seen for example in speaker cones and the like. This allows for a better mass-impedance match between the transducer and the shell, allowing for more efficient transmission of energy from the transducer to the outside medium (the flexible shell portion acting as the intermediary). In these membrane embodiments, the vibration will be more directional (as in a speaker) allowing for targeted agitation of the medium. If the transducer is pulsed, then sufficient mechanical force may be exerted by the flexible membrane to cause the immersion device 100 to translate to a desired direction. If there are several membranes disposed about the shell 110, then a form of propulsion using the transducers can be obtained. These and other aspects of transducer manipulation in concert with shell material makeup are contemplated as being within the scope of one of ordinary skill in the art and therefore within the scope of this disclosure.
With respect to communications, instead of utilizing sonic means, alternate communication means, such as a multi-use sensor 155 or induction coil 140 (operating as an antenna) could be used in addition to transducer 150. Further, optical means such as an LED, laser, and/or photo-sensor could be used. The latter example could be used in a medium that is moderately transparent to light (for example, high proof alcohol). For efficiency of transmission, portions of shell 110 adjacent to the communications means 155 would be appropriately transparent to the mechanism of communication. It should be apparent that sensor 155 shown may be replaced with a communications means or, if the sensor 155 is capable of providing communications, operate as a sensor/communication device. Of course, multiple sensor and/or communication devices may be implemented within immersion device 100, according to design preference.
In addition to sonic stimulation, light-based stimulation could also be achieved in immersion device 100 if fitted with a light source, such as an LED. In
In some configurations and environments, it may be useful to control the buoyancy of immersion device 100 via an optional buoyancy tank 190. A micro pump (not shown) inside shell 110 would fill or empty buoyancy tank 190 by pumping air in or out. One example of a possible way of implementing this is by attaching the micro pump to an inflatable membrane that alters the surface volume of immersion device 100 or pumps air out/in of shell 110. Any means for affecting buoyancy may be employed.
When primary board 120 is equipped with an induction coil 140 to receive external wirelessly transmitted power, those skilled in the art will recognize that fields between the induction coil 140 and the external field will cause a force. Depending on how the external electromagnetic field is oriented, immersion device 100 can be directed and rotated in this fashion. This can be useful for several purposes such as moving immersion device 100 inside the medium, stirring the medium, and better distributing the mechanical energy irradiated by immersion device 110. In some embodiments, sections of the shell may composed of a material that is magnetically sensitive or magnetized by an external field. Therefore, for retrieval of the immersion device 100 can be more effectively accommodated by “magnetizing” the shell, so as to allow a metal rod inserted into the container to magnetically retrieve the immersion device 100.
In some embodiments, one or more magnet(s) 195 (or ferromagnetic or field sensitive metal) can be positioned within shell 110 for alignment purposes, or. In experimental models, a immersion device 100 was centered to an external energy transmitting coil (not shown) via coupling between the shell's rare earth magnet 195 and a secondary rare earth magnet in the transmitting coil. With “centering,” a higher energy coupling efficiency was achieved between the transmitting coil(s) and the receiving/induction coil 140. In some embodiments, a plurality of magnets (whether rare earth or not) may be used to gauge the amount of coupling efficiency or desire to center (or in some instance, not-center) the immersion device 100 to transmitting coil(s). In other embodiments, a combination of magnets and ferromagnetic/metal elements may be used to assist in drawing the immersion device 100 towards an externally placed (outside the container) power transmitting coil.
As stated above, secondary board 130 can contain several types of sensors 155, depending on the tasked application. Further, sensors 155 may require sampling the external medium, therefore a sample port 158 may be accommodated. Further, in some instances, it may be desirable to introduce a chemical or substance into the medium, originating from the immersion device 100. Thus, sample port 158 can operate as a means for introducing the substance into the medium. Typical sensors 155 (some which require a port to sample the medium) that can be embedded on the secondary board 130 are: temperature sensors, pH sensor, specific gravity, liquid opacity, and so forth. The secondary board 130 can also contain non-medium related devices/sensors such as accelerometers, gyroscopes, GPS, etc. As stated above, one or more of these sensor electronics can be contained on primary board 120, according to design preference.
For exhaust gases generated by the fuel cell 135, an opening or channel 165 may be provided to a chamber 175 within shell 112. Typically, but not necessarily, channel 165 may be of a one-way vent allowing the exhaust or waste product gases to vent into chamber 175. If chamber 175 is configured to be of a flexible membrane, then when sufficient gases are vented into chamber 175, it will expand to affect the buoyancy of the immersion device. Therefore, upon a complete cycle of fuel cell use, the chamber 175 can be configured to “bloat” to a degree that will cause the immersion device to float to the surface of the medium. This scenario is particularly effective if the shell 112's lower section is actually replicated by the flexible chamber 175. In some embodiments, chamber 175 may be separable from the shell 112, thus enabling the retained exhaust gases to be dispensed from the immersion device after the immersion device is retrieved from the medium.
In some embodiments, the immersion devices 220 can be configured to also communicate between themselves and serve as a relay to transfer information to the base station 250. Assuming that one immersion device 210 wants to send data to the base station 250, it can use a secondary nearby immersion device 210 as a relay. This is advantageous in that it requires less power to transmit data to a nearby relay, and relaying allows the data to be retransmitted farther. In some embodiments, immersion devices 210 can be configured to communicate directly to other devices or external devices such as mobile device or computer using light, RF, sound or ultrasound, depending on its configuration. In some embodiments, one or more of the immersion devices 210 may surface to allow communication.
In some embodiments, a combination of agitation via the base station 300 and agitation via the immersion devices may be implemented. Of course, the agitation afforded by base station transducer 310, not being within the medium itself, will be less efficient than an immersion device. The benefit, however, of having a non-immersed agitation source is its power can be provided by a “hard” mains powered line. Further, loss of efficiency can be compensated by using a stronger more robust base station actuator 310.
The base station 300 includes power electronics 330 to convert power from mains line power 340 to the desired frequency and amplitude for transmission coil 320. Mains line power cord 340 can connect directly to an ordinary line (AC) outlet or to a DC power supply, depending on the system configuration.
Communications electronics 350 can be a feature of base station 300, and may have an optional external communication port or be configured with an antenna for wireless communication, or an optical link. Communication can be facilitated via any known or future known system, using any protocol, for example using WiFi, Bluetooth, ZigBee, NFC, USB. Cellular, Fiber, or any other sort of wired or wireless communications that can send and receive information directly or indirectly to a computer or mobile device such as a cell phone or tablet.
This enables base station 300 to communicate externally to commercial devices, but also allows base station 300 a non-acoustic mechanism to communicate to immersion devices within the medium, for example. If linked to the Internet or to a network, the base station 300 can be fully controlled from an external mobile device or computer. Having remote control capabilities allows the immersion devices within the medium to transmit information about the medium or actuate on the medium without the need for an operator to be physically present.
Base station 300 supplies power to the immersion device(s), via the generation of a wireless electromagnetic field which can be tapped by the immersion device(s). To assist centering or aligning the immersion device, magnetic or magnetically sensitive material 370 may be disposed at the top of base station 300. For wireless power transfer, base station 300 contains a transmitting coil 320 to generate an electromagnetic field above (or below) the base station 300. Immersion device(s), sensor device(s) or other devices as described above can thereby tap into the generated electromagnetic field to obtain the needed power. For best transmission of the electromagnetic field, the base station 300 enclosure (specifically the top portion) would be constructed of a non-electromagnetic energy interfering material. The induction coil 320 may be a single coil or multiple coils, depending on design preference. In several experiments, it was discovered that for a given set of constraints (size, number of loops, etc.) multiple coils having a mutual inductance were more effective in generating the desired electromagnetic field energies.
In some embodiments, the coil(s) 320 are displaced from the base station 300 and disposed adjacent to the container under agitation. In these embodiments, the base station 300 provides the “power” for the coil 320 only, via cables (not shown).
For example, in one embodiment, a pair of dual coils can be used for the induction coil 320 and for the induction coil 140 of immersion device 100 (
For example, in one experiment using a wirelessly powered configuration, the transmitting coil was approximately 1.97″ in diameter and composed of Type 4 Litz wire, using either 1 layer coil or 2 layer bifilar coils having 10 loops. In this embodiment the transmitter signal was generated by a base station comprising a signal generator connected to an RF amplifier, set as a square wave at approximately 100 kHz+/−25 kHz, and cabled to the transmitting coil. The amplitude of the transmitted signal from the RF amplifier was approximately 20 V-pp. The test base station utilized an AC/DC converter to convert the line current to DC, which was fed to a 555C timer outputting to a 2N6782 transistor pulling a 22 uH transmitting coil. A 1 uF capacitor was series connected between the output of the 555C timer and the transistor, and input biased with 1 k resistors. As should be understood, various modifications and changes may be made to a base station transmitting circuit, by one of ordinary skill in the art and therefore are understood to be within the scope of this disclosure.
The corresponding electronics of the immersion device comprised a single 12.3 uH receiving coil in parallel with a 330 uF capacitor. The receiving coil was a 10 loop, sized as 1.18″ L×1.16″ W×0.03″ H. The output was fed into a rectifying bridge and to a 2,220 uF load capacitor. The output of the load capacitor was fed to 24 mm vibration motor/transducer from Precision Microdrives model 324-401, having a 12 VDC input rating and 140 mA. The motor runs at a rated 5,400 rpm (5.4 kHz), which varies as function of current and amplitude. As should be understood, various modifications and changes may be made to the immersion device's circuitry, by one of ordinary skill in the art and therefore are understood to be within the scope of this disclosure.
In several visual coloration tests, small containers (approximately 1 quart) containing alcohol (ABV 40%-70%) and an approximately a tablespoon charred wood were situated above a base station/transmitter coil. In these tests, the transmitter's RF amplifier's output was connected to the transmitting coil and also a resonant (tank) circuit. To assist in aligning the immersion device to the transmitting coil, a rare earth magnet was placed within the transmitter coil. An immersion device was placed inside the container and power turned on to the transmitter coil. After 24 hours, a clear change in color of the alcohol occurred due to extraction of the charred wood, with the agitated medium visibly darker than the non-agitated control.
It is also worthy to mention that one or more of transducer/actuator(s) 310 can also be replaced with a light source (or a light source added) and therefore perform photo stimulation of the medium in any range of the spectrum including Ultra Violet, Infrared or visible light. This, of course, presumes the medium's container is light-transmissive. It is known that some materials/biological/chemicals, etc. in some media are beneficially responsive to light stimulation and accordingly light stimulation may be facilitated a base station light source. If so configured, base station 300 may optically communicate to/from immersion device(s).
The EEE system can also be deployed using another architecture, where indirect energy transfer is used via resonant principles to increase effectiveness.
In some embodiments, the outer shell 410 can have an orifice 425 that can be used for tuning purposes or permit medium liquid to enter/exit resonant cavity 420. In some embodiments, there will be a plurality of orifices 425, provided the resonant cavity characteristics are not too deteriorated by the presence of the additional orifices 425. With the introduction of medium liquid into the resonant cavity 420, one mode of energy “transference” can occur upon the cavity-contained medium liquid. That is, rather than purpose to radiate energy outwardly into the external medium, one possible mode would be to introduce the external medium liquid “into” the resonant cavity 420 and then radiate energy into the cavity contained liquid. Another mode would be to provide dual radiation of energy—externally into the medium and internally into resonant cavity contained liquid.
With an induced flow of medium entering the resonant cavity 420 and exiting the resonant cavity 420, depending on the cavity shape, such a system could act as a pump, pushing medium through the cavity 420. If a plurality of orifices 425 are instituted, then “controlled flow” could be generated. As stated above, the resonant cavity 420 can be of a different shape, configuration, etc. than as shown.
It is fully contemplated that with appropriate shaping and design of the orifices 475 with cavities, the immersion device 450 could take advantage of the resulting resonant “pumping” action to generate propulsion. That is, as flow is being generated, it could be asymmetrically generated to cause the immersion device 450 to move, rotate, etc. With frequency modulation or shifting of the transducer frequency, movement could be controlled. It is fully contemplated that one or more resonant cavities could be configured to expel medium, at a given frequency, so as to increase the buoyancy of the immersion device 450 to cause it to rise to the surface of the medium. Though not expressly shown here, the immersion devices may be configured with a ballasting system as earlier described. Or, alternatively, one or more of the resonant cavities described above may be configured as a ballast system. For example, at a particular frequency, the designated resonant cavity may “bulge” or expand (presuming it is of an expandable material), so as to cause the immersion device to increase its buoyancy. Alternatively, the cavity may shrink, to reduce the immersion device's buoyancy. One or more cavities may be evacuated of any fluid, causing air to form in the cavity and produce ballast.
It is understood, given the disclosure provided above, that changes and modifications may be made to various shapes, configurations and so forth to the above systems without departing from the spirit and scope of this disclosure. For example, the cavities may be multi-shaped, multi-chambered, etc.
In addition to electromechanical stimulation of a medium via an EEE system, a hybrid system is contemplated where an internal EEE system can be utilized with an external transducer system.
External (non-immersive) transducer 530 is attached to the vessel's 520 outer surface and controlled by power source/signal generator 560 having external power connection 580. Such a system 500 could provide micro and macro agitation, where depending on power capabilities the EEE immersion devices 510 could target the “deep” interior portions of the vessel 520 while the external transducer 560 could target the outer portions of the vessel 520. With different transducer systems, different frequency and/or agitation profiles could be generated and exploited.
Further, EEE immersion devices 510 could also be set to a frequency of resonance that is coincident with external transducer 560. That is, external transducer 560 could be the source of resonant frequency energy for a resonant cavity EEE immersion device 510, rather than the immersion device 510 itself. In this manner, not only could external transducer 560 cause EEE immersion device 510 resonance “flow” from mechanical energy arriving from external transducer 560, it is contemplated that a buoyancy condition for the immersion device 510 could be based on external transducer 560. For the latter case, the external transducer 560 frequency could be set to trigger one or more immersion devices 510 to change their buoyancy. Such a design would fish up all (or only a designated one) immersion devices 510, including dead ones that could not on their own alter their buoyancy (for example, due to loss of internal power). Similar to controlling buoyancy, movement in a lateral or vertical plane could also be effected.

For large systems, a single transducer system 600 may prove to be easier to manage and if provided with enough surface area/depth and power, effective fermentation/activation of the medium can occur. The above system contemplates that there will be a large opening at the top of vessel 620 (which typically is) so entry to the vessel 620 can be easily accommodated for. Equivalently, any port with access to the interior of the vessel 620 could be utilized with appropriate means for sealing the port designed into the embodiment. While the term “rod” has been used, it is understood that any shape may be used, as evident in the branch shown
Transducer 712 is shown as an alternative mounting procedure and powering mechanism. Specifically, transducer 712 is “attached” to an internal mount 755 that is affixed to the wall (or side) of vessel 720. This approach presumes mount 755 breaches the wall of vessel 720, but is done in a manner that does not compromise the vessel's integrity. Also, powering of transducer 712 can be though a direct line 790 which is fed through a port or opening in vessel 720. Alternatively, transducer 712 may be powered via a direct connection 795 from neighboring transducer 710, or vice versus. As is apparent, multiple transducers may be internally positioned within vessel 720 and as such, beam forming can be achieved through proper phasing.
The vessel 720 can also act as a resonant cavity and therefore appropriate positioning of transducer(s) 710, 7154 can result in resonance occurring or not occurring. In some instances, it may be desirable to place the transducer(s) 710, 715 near the bottom of vessel 720. In other instances, it may be desirable to have a plurality of transducers arranged on the sides and/or bottom and/or top.
It should be noted that each of the signal generators and/or related transducers in any one of the above embodiments, may be configured to “communicate” to each other or to another device. For example, a transducer may be equipped with sensor/measurement capabilities to determine the temperature, specific gravity, acidity/alkalinity of the medium and relate that information to an external system/computer. The external system may be attached to the transducer or to the signal generator, or may be communicated to via a wireless connection. Accordingly, operation of the system can be managed remotely as well as monitoring the performance thereof.
It should also be noted that various EEE immersion devices may be used in combination with these “large” transducer systems of
Accordingly, it is contemplated that one of ordinary skill could deploy a system of EEE immersion devices with sensor only capabilities, wherein the sensor data is communicated to the communications-capable internal transducer. The internal large transducer would provide the desired electromechanical agitation effect, while the EEE sensors would provide measurement data, which would be forwarded by the internal large transducer to the appropriate external computer.
Various embodiments described above may be applied to beer fermentation, alcohol/spirits aging, wine aging, yogurt, kombucha, chemical reactors, and other “processes” where fermentation, aging and/or agitation is required of the target medium.
It should be understood that while the various examples shown above are in the context of fluids containing alcohol, such as beer, wine, spirits, etc., the systems and methods described can be used for non-alcohol based mediums, where a mechanical form of agitation is desired but without the use of “physical” large object stirrers or paddles, which may crush the medium components. For example, chemical tanks can be “stirred” by the systems and methods described herein. Furthermore, medical solutions that need agitation could similarly benefit from these systems/methods. Biological solutions could have their growth/reaction times reduced by the stimulation of the growth medium.
As can be appreciated, various different deployment schemes and applications are made possible via the flexibility of the systems and capabilities described. Therefore, it understood that many additional changes in the details, materials, steps and arrangement of parts, which have been herein described and illustrated to explain the nature of the invention, may be made by those skilled in the art. And that such alterations are within the principle and scope of the invention as expressed in the appended claims.
