The present disclosure generally relates to devices and methods for transferring material between substrates, and more specifically to the control of material transport using composition and phase modulated transport media.
Handheld tools may undergo harsh use. For example, tools used to grind or scour away materials may become clogged with debris, and may frequently need to be discarded and replaced. Similarly, brushes and applicators used to apply materials to surfaces may similarly become clogged with materials and cease to function optimally. Removal of materials such as contaminants, dirt, oils, extracts, or the like from a substrate may be desired for purposes such as cleaning, production of plant extracts, or other implementations. Water-based methods may damage items such as makeup brushes, especially for items including specialized natural or synthetic materials that require special care. Water-based methods may further be ineffective for removing or extracting hydrophobic compounds such as oils or plant extracts. Moreover, cleaning of cosmetic brushes or other items with water may require extensive drying times during which mold and bacteria can grown on or within the substrate. Hydrocarbon solvents can be an alternative to water-based methods, but may be hazardous to users and the environment.
The systems, methods, and devices described herein have a number of innovative aspects, no single one of which is indispensable or solely responsible for their desirable attributes. Without limiting the scope of the claims, the summary below describes some of the advantageous features.

Certain embodiments of the present disclosure will now be described, by way of example only, with reference to the accompanying drawings. From figure to figure, the same or similar reference numerals are used to designate similar components of an illustrated embodiment, unless stated otherwise.
Although the present disclosure is described with reference to specific examples, it will be appreciated by those skilled in the art that the present disclosure may be embodied in many other forms. The embodiments described herein are merely illustrative and do not limit the scope of the present disclosure.
In the description which follows, like parts may be marked throughout the specification and drawings with the same reference numerals. The drawing figures are not necessarily to scale and certain features may be shown exaggerated in scale or in somewhat generalized or schematic form in the interest of clarity and conciseness.
Generally described, the present disclosure provides systems, methods, and devices for transporting mass from a first substrate and/or between a first substrate and a second substrate by way of carefully controlled composition and phases of transport media. In various embodiments, transporting mass from a first substrate can include the cleaning of items such as textiles, garments, natural and synthetic fibers. In some embodiments, transporting mass from a first substrate can include the cleaning of utensils such as makeup brushes, other cosmetic applicators or utensils, smoking utensils (e.g., pipes, water pipes, hookahs, etc.), surgical utensils, electronic components such as circuit boards, or the like, by removing contaminants such as tars, greases, oils, or other materials from the surface of the utensils. A first substrate can be exposed to transport media such as supercritical CO2 or other gases, such as in a sealed and pressurized environment, or by exposure to a directed stream of transport media, such that materials can be removed from the first substrate, even if the materials are physically bound by small cracks or other features of the substrate (e.g., brush bundles caked with cosmetic foundation materials). In some embodiments, transporting mass from a first substrate can include extracting components such as essential oils, tobacco extractions, cannabis extractions, or the like. Moreover, some embodiments of the present disclosure may simultaneously treat the first substrate and/or the transported mass, such as by sterilizing, conditioning, softening, flavoring, adding fragrance, or the like.
In some embodiments related to cleaning of a first substrate, the transported material, e.g., contaminants, are waste products and can be exhausted into the atmosphere and/or can be deposited into a receptacle. For example, contaminants can be deposited into a plastic or metallic pan, for convenient disposal. In another example, contaminants may be deposited into a filter, such as a paper or cloth filter, while some or all of the transport medium passes through the filter and is exhausted into the atmosphere. The systems and methods described herein can provide a thorough cleaning or extraction process, removing materials located in relatively inaccessible cavities of a substrate and depositing them in an easily disposable or storable container, while leaving the substrate dry and free of transport media.
In some embodiments related to extraction of substances such as essential oils, tobacco extractions, cannabis extractions, or the like, the extracted substances are of a usable form, and may be deposited into a storage container, such as a jar a vial, or the like.
As will be described in greater detail below, embodiments of the present disclosure may utilize transport media including supercritical fluids. Generally, a supercritical fluid may be described as a substance at a temperature and pressure above its critical point, such that distinct liquid and gas phases do not exist, and the substance incorporates properties of both gas and liquid states of the substance. For example, the substance may be effusive and simultaneously able to dissolve particles. Generating and handling supercritical fluids, such as supercritical carbon dioxide (CO2), may be difficult and/or hazardous for an unskilled user. Thus, the systems and methods described herein can provide for simplified operation by an unskilled user. For example, a material transport device may be configured to use transport media provided in sealed single-use or multi-use canisters (e.g., canisters of pressurized CO2, puncturable foil-sealed containers, etc.) that are relatively easily handled without specialized training.
In various embodiments, material transport devices described herein may be compact, lightweight, and portable, and may be configured to require relatively little to no power for operation. Accordingly, in some embodiments, the devices may be transportable in a backpack or handbag. Moreover, the devices may be operable in locations where an AC power supply is not available. Alternatively, the material transport devices may be incorporated in larger embodiments, for example, in larger standalone devices for installation in retail or kiosk environments, or in a large high-throughput tractor trailer-mounted unit for transport. In some embodiments, the material transport devices may provide for environmentally friendly disposal of transported materials, such as in a solid form that can be easily deposited in a landfill, rather than washed into groundwater or other water system. In addition, the material transport devices may be used to transport media from a substrate without introducing any hydrocarbon solvents to a user or the environment.
The pressure vessel 305 includes a lid 308. The lid 308 can be sealable to contain material transport media and any transmitting and receiving substrates within the pressure vessel 305. In some embodiments, the lid 308 is securable in a closed position by a latch 310. In some embodiments, the lid 308 may be securable by a screw-type closure or other securing structure. A heating element 303 is located in close proximity to at least a portion of the pressure vessel 305 to provide temperature control of the transport media. For example, the heating element 303 may be a coil or resistive heating band extending around the exterior of a portion of the pressure vessel 305.
The transport media housing 401 is configured to hold a supply of one or more transport media outside the pressure vessel. In the embodiment depicted in
The computer components 301 may be external to the pressure vessel 305 and transport media housing 401, and/or may be combined with or attached to the pressure vessel 305 or transport media housing 401. The computer components 301 are connectable to a power source. A controller, such as a microcontroller, integrated circuit, or the like, along with a user input, can be used to control the process of modulating phases through heat and movement of the material transport media. Specialized cycles can be selected through the user interface to optimize the cycles of phase changes for specific materials and substrates. In various embodiments, the user input may allow a user to customize aspects of a material transport cycle, such as temperature, phase, duration, etc. In some embodiments, predetermined cycles may be provided automatically such that a user can initiate a material transport cycle by pressing a single button or selecting from several options provided. Automated material transport cycles may be customized to a particular substrate type, for example, a particular plant for extraction, or a particular brush type or set of brush types with natural or synthetic bristles.
The material transport device 800 includes a door 803 operable by a handle 801. In some embodiments, the door 803 can be partially or entirely composed of a transparent or translucent material. The door 803 may further be hinged and/or slidable for pleasing aesthetics, such as in a luxury lavatory or salon setting. In some embodiments, the handle 801 can be lockable by a cam lock or other locking system (not shown) to secure the pressure vessel. The trays 850 in the interior 853 of the material transport device 800 may be moveable within the interior 853 and/or may be removable for maintenance, cleaning, and/or accommodation of large or irregularly shaped substrates. The material transport device 800 can further include legs 150 which may provide thermal insulation between the material transport device 800 and the surface below, such as a desktop, tabletop, counter, or the like.
One or more cartridges containing a transport medium can be loaded at the top of the device. In the example embodiment depicted, the cartridge is loaded by lifting a handle or pullup lever 815 that opens and/or locks the cartridge chamber lid 823. When the lever is opened, a cartridge may be placed into a transport media housing 842, which may include a nozzle or other structure for securably receiving the cartridge. Once lever 815 is closed again, the cartridge can be punctured and the transport medium released to start the process of moving materials from substrates within the material transport device 800. In some embodiments, the transport medium within the cartridge can be pure CO2, or can be CO2 mixed with a relatively smaller amount of a co-solvent such as alcohol, and/or one or more additional agents for flavoring, scenting, strengthening, condition, or otherwise treating the substrates within the material transport device 800.
The transport material (e.g., effluent) can be deposited in a pullout tray 806 located at the bottom of the material transport device. The pullout tray 806 may have sufficient capacity to collect effluent from several cycles of material transport events. For example, the pullout tray 806 may be large enough that it need only be emptied after 2, 5, 10, or more material transport cycles. The pullout tray 806 may be reusable or may be disposable. A button 841 may be provided to allow a user of the material transport device 800 to initiate a material transport cycle. In some embodiments, computer control of the transport cycle may be automatic and may be configured to ensure proper transport of cosmetic materials from synthetic and natural brush substrates located within the material transport device 800, such that the material is deposited in the tray 806 for easy disposal. In some aspects, the button 841 may be configured to color to indicate various stages of the material transport process.
Moreover, the material transport device 800 may further include light sterilization functionality, such as by ultraviolet germicidal irradiation or ultraviolet sterilization. For example, the material transport device 800 may include one or more UV light sources (not shown) configured to expose substrates located on the trays 850 to UV radiation for a desired amount of time. In some aspects, the UV light sources may be located at the top of the material transport device 800, and/or may be disposed along vertical surfaces of the interior 853 to provide even irradiation when a plurality of items are in the material transport device 800. UV radiation may be provided by one or more UV LEDs or other UV emitters. UV sterilization can be performed as a standalone cycle or as an enhancement to a material transport cycle, and may be implemented before, during, and/or after the material transport cycle. In various embodiments, the wavelengths provided by the UV light sources may be within the range of 100 nm and 400 nm, or a sub-range such as between 200 nm and 300 nm, between 240 nm and 280 nm, or other suitable wavelengths.
In some embodiments, the material transport device 500A includes a cartridge system 369 in addition to or instead of the pressure vessel 373 as the source of material transport media. In some embodiments, receiving material transport media from a sealed cartridge 367 may enhance safety and ease of use. A cartridge system valve 365 controls the flow from the cartridge system 369 to the valve and regulator 362 when both a cartridge system 369 and pressure vessel 373 are provided. The cartridge 367 can be sealed with a puncture type seal at the top. When the cartridge 367 inserted into the cartridge system 369, the seal is punctured and the transport medium within the cartridge 376 can be delivered under pressure to the system through the valve and regulator 362 into the dispensing chamber 376. In some embodiments, the dispensing chamber 376 has plumbing and apertures to deliver the phase and composition controlled transport medium into the chamber at the relative location where it can be most effective at cleaning a substrate 379 mounted within the chamber 381. For example, the substrate 379 can include brushes, smoking devices, or the like, held into position using rigid or elastomeric securing means. The chamber 381 can be accessible by the user for ease of access in loading and unloading substrates for cleaning. In some embodiments, the dispensing chamber 376 is in fluid communication with an array of jets 378 surrounding the substrate 379.
An effluent from the chamber may comprise a combination of transport media in a phase and composition modulated state, as well as material transported from the substrate 379. The effluent exits the chamber 381 at a regulated pressure by way of a pressure and flow regulator 385. A gauge 383 monitors and reports to the controller 387, and may further read out on a display the progress of the reaction and transport of media. The effluent may continue to a condenser coil system 389. The condenser coil system 389 may allow the transport media and transported material within the effluent to at least partially return to an ambient temperature and/or pressure. The condenser coil system 389 further delivers the effluent into a diffusion tank 452, where it can be equilibrated with the atmosphere. The effluent is expelled through a filter holder 455 into a filter 457 and/or a tray 459 or other second substrate. The tray 459 and/or filter 457 can be removed easily for disposal of the collected media that was transported from the first substrate 379 in the chamber 381. In some embodiments, a heating element (not shown) may allow the transported material to be pyrolyzed and/or deposited on the tray by evaporative deposition. In one example, the filter 457 is a screen filter (e.g., a metal screen filter) capable of withstanding high temperatures, such that the material deposited on the screen can subsequently be pyrolyzed by a heat source such as a flame or torch. In some aspects, the heat source can be a coil or other heating element within the device 500A, or may be an externally applied heat source.
In another embodiment, depicted in
A pressurized and foil sealed cartridge 189 is pressed onto a seal puncture system 106 and contained within a holder 701. After the foil seal 111 is punctured, the cartridge 189 delivers a transport medium under pressure to a pressure chamber 197, which may include a plumbing feature such as a tube or pipe, or the like. In the pressure chamber 197, the contents are heated to a predetermined temperature or range of temperatures via a heating coil 211 or heated jacket by current source 213. The current source 213 can be controlled by a microcontroller or other computer-programmable integrated circuit device. The contents of the pressure chamber 197 are contained under pressure by a pressure release valve 309 until a predetermined threshold release pressure is achieved. In some embodiments, the temperature range and release pressure can be determined so as to ensure that a known transport medium within the pressure chamber 197 will be in a supercritical or near supercritical phase. In some aspects, the pressure release valve 309 can be a check valve, such as a spring mechanical check valve, configured to open upon reaching a threshold pressure and to prevent backflow into the pressure chamber 197.
Once the release pressure is achieved, the transport medium 312 in a supercritical or near supercritical phase is sent through jets nozzles 313 into the brush material 21 or other portion of a brush 31 or other substrate to be cleaned. The brush material 21 is fully engulfed in the supercritical or near supercritical transport medium 19 due to the flow from the jet nozzles 313. As the supercritical or near supercritical transport medium 19 flows around the brush material 21, particles of material, such as various contaminants to be removed, are carried by the stream of the transport medium 19 to form an effluent containing the transport medium and the particles of transported material. A screen 83 isolates a collection chamber 72 from the brush 31 and other substrates. The effluent can then be removed to a vacuum chamber 27, which can create a partial vacuum or negative pressure through port 16 in fluid communication with the collection chamber 72. The port 16 can be an outlet port. In some embodiments, the port 16 is located in the lower 50% of the device such that the collection of particles and transport medium can be assisted by gravity. The screen 83 can support the brush 31 while allowing the effluent to pass through to the collection chamber 72 and the vacuum chamber 27. In some embodiments, the transport medium may cool to a non-supercritical state, such as a gas phase, and may leave the device 500B through holes 30, while the transported materials may pass downward through the screen 83.
The material transport device 700 may be battery powered, for example, by a battery 587 located at a first end of the device 700. The battery 587 can be any type of commercially available electrochemical cell. The battery 587 can be disposed adjacent to a cartridge container 592 surrounding a cartridge 593 containing a transport medium. The battery 587 powers a heater 589 adjacent to or surrounding the cartridge 593, such that the heater can drive phase states that are above room temperature. In an example implementation, a user may insert a cartridge 593 into the cartridge container 592. An activator puncture pin 597 punctures a seal 594 of the cartridge 593. Thus, the cartridge 593 delivers the transport medium contained therein to a valve regulator system 595. In some embodiments, the valve regulator system 595 may be controlled by a mechanical trigger 673. The device can be controlled by a controller or other computer or processing circuitry. In various embodiments, the trigger 673 can directly control the valve regulator system 595, and/or may initiate an automated process in which the valve regulator system 595 is controlled by the controller or other circuitry. In non-powered embodiments, the mechanical trigger 673 may directly cause the transport medium to flow from the pressurized cartridge 593 into the chamber 591.
The chamber 591 can be configured to hold various single or multiple substrates 599 so as to receive the modulated transport media from the cartridge 593 by way of guided jets 659 emitted from the valve regulator system 595. The substrate 599 can be held in an optimal position by a substrate retainer 671, such as a collar, mesh container, or the like, in the chamber 591. The substrate retainer 671 can be selected based on the type of substrate to be treated. In some embodiments, multiple interchangeable or simultaneously usable substrate retainers 671 may be provided for use with the material transport device 700. For example, the substrate retainer 671 may include a collar or elastomeric strap for retaining a brush, pipe, water pipe or hookah component, or the like. The substrate retainer 671 may further include a mesh enclosure or other permeable container for retaining organic material such as tobacco, cannabis, or plant matter containing essential oils or other extractable substances.
After passing the substrate 599 and collecting material therefrom, the transport medium and transported material is expelled as effluent at ambient pressure through a diffuser 661. The material that was transported from the substrate 599 is deposited on a filter 667 and/or in a second substrate 665. The transport medium then exits the material transport device 700 to the atmosphere through a diffusion bell 663. In some embodiments, depositing the transported material on a second substrate 665 may be desirable for solid disposal in an appropriate waste container without consumable products. In extraction-related implementations, the second substrate 665 may include a storage vessel for storage of essential oils, cannabis or tobacco extracts, or the like extracted from the substrate 599 by the transport medium.
The material transport device 900A includes a pressure chamber 928 for conditioning of transport media, and an extraction chamber 949 configured to retain a substrate for material transport as described elsewhere herein. The pressure chamber 928 is associated with a temperature sensor T1 923 and a heating element HE1 929 for monitoring and control of the temperature within the pressure chamber 928, and a pressure sensor P2. Similarly, the extraction chamber 949 is associated with a temperature sensor T2 951, a heating element HE2, and a pressure sensor P3 941. The material transport medium comprises a mixture of one or more of CO2, ethanol, and helium. Valve 911 controls the flow of CO2 into the mixture, valve 912 controls the flow of ethanol into the mixture, and valve 914 controls the flow of helium into the mixture. A pressure sensor P1 917 monitors the pressure of the transport medium outside of the pressure chamber 928. Valve V1 921 controls the flow of the transport medium into the pressure chamber 928. Valve V2 935 controls the flow of the transport medium from the pressure chamber 928 into the extraction chamber 949. Valve V3 945 controls the flow of effluent, including the transport medium and particles of transported material out of the extraction chamber 949 (e.g., into the atmosphere, to a receiving substrate, etc.).
As shown in
The controller can be configured to evaluate one or more equations and/or use one or more lookup tables contained in a computer memory in communication with the controller, to determine a phase of the transport medium in the pressure chamber 928 or the extraction chamber 949 of the material transport device 900A. The computer memory may further include one or more sets of computer-executable instructions that cause the controller to perform a series of heating and valve control steps to carry out a material transport sequence.
With reference to
When valve V2 is opened, the supercritical mixture flows into the extraction chamber 949 as a material transport medium. Temperature sensor T2 and pressure sensor P3 monitor the temperature within the extraction chamber 949 to determine if the material transport medium is still in a supercritical or near supercritical phase. If the temperature drops too low, the controller can activate heating element HE2 to ensure that the material transport medium remains supercritical or near supercritical. The material transport medium can be contained within the extraction chamber 949, or may be vented to the atmosphere or a receiving substrate if the controller opens valve V3. In some embodiments, a pre-soak or pre-treatment mode may be utilized. In a pre-soak or pre-treatment mode, a lower-pressure liquid or gas phase may be introduced to the extraction chamber 949 for enhanced cleaning or extraction. Following the pre-soak or pre-treatment mode, an ordinary material transport sequence may be carried out as described above. In further embodiments, the material transport sequence may be followed by a post-treatment operation, for example, including the use of compressed gases to blow dry the substrate in the extraction chamber to ensure that the substrate is dry before removal. In another example, the post-treatment operation can include the use of post-treatment agents or UV light to sterilize the substrate.
Referring to
The material transport medium comprises a mixture of one or more of CO2, a solvent, and a co-solvent. Valve 2011 controls the flow of CO2 into the mixture, valve 2012 controls the flow of the solvent into the mixture, and valve 2014 controls the flow of the co-solvent into the mixture. A pressure sensor P1 2017 monitors the pressure of the transport medium outside of the pressure chamber 2028. Valve 2021 controls the flow of the transport medium into the pressure chamber 2028, through a one-way valve 2025 to prevent backflow of material transfer media from the pressure chamber 2028. Valve 2035 controls the flow of the transport medium from the pressure chamber 2028 into the extraction chamber 2049. Valve 2045 controls the flow of effluent, including the transport medium and particles of transported material out of the extraction chamber 2049 to a receiving vessel 2037, such as a vacuum, storage container, or the like.
Referring now to
The material transport medium comprises a mixture of one or more of CO2 and an inert gas. Valve 1011 controls the flow of CO2 into the mixture, and valve 1012 controls the flow of the inert gas into the mixture. A pressure sensor P1 1017 monitors the pressure of the transport medium outside of the pressure chamber 1028. Valve 1021 controls the flow of the transport medium into the pressure chamber 1028, through a one-way valve 1025 to prevent backflow of material transfer media from the pressure chamber 1028. Valve 1035 controls the flow of the transport medium from the pressure chamber 1028 into the chamber 1049.
