Abstract
Description
[Technical field]
[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to U.S. Provisional Application No. 63 / 337,661, filed May 3, 2022, entitled "Cryogenic Grinding Systems, Apparatus, and Methods of Use Thereof," which is incorporated herein by reference in its entirety.
[0002] FIELD OF THE DISCLOSURE The present disclosure relates generally to cryogenic grinding or comminuting equipment, and more particularly to cryogenic grinding systems. [Background technology]
[0003] Cryogenic grinding or milling is often used to reduce samples to a particle size suitable for analysis. Cryogenic grinding or milling often involves cooling or removing heat from the sample, allowing the sample to be ground into a smaller particle size for further analysis. However, in the past, the systems and methods used for cryogenic grinding or milling often required multiple tedious steps by a technician. Furthermore, past systems and methods often required trial and error to achieve proper sample processing, which resulted in waste of energy and materials (e.g., cryogens) as well as waste of the sample that needed to be processed. The present disclosure overcomes these shortcomings by providing a reliable and efficient method of processing samples via cryogenic grinding. Summary of the Invention

[0018] By way of background, an overview of the aspects of the present disclosure and advantages it provides is provided. This overview, and the detailed description that follows, are presented for purposes of illustration and description. It is not intended to be exhaustive, nor is it intended to limit the present disclosure to the form described. Numerous modifications are possible in light of the above teachings, including combinations of the above-described aspects. Some of such modifications have been discussed, and others will be apparent to those skilled in the art.

The scope of the present disclosure is, of course, not limited to the examples or aspects described herein, but may be adopted by those skilled in the art in any number of applications and equivalent devices. Rather, it is intended that the scope be defined by the claims appended hereto.
[0019] (II. Overview) As described in further detail below, aspects of the disclosure relate to improved cryogenic grinding systems, apparatus, and methods. The cryogenic grinding system includes a body and a sample-containing vessel having one or more blades therein. After a sample is placed in the sample-containing vessel and the vessel is placed in the body, a cryogen is supplied to the vessel to remove heat from the sample. The blades in the vessel are rotated, which results in the sample being reduced to a size suitable for further analysis. Detailed examples of the disclosed systems, apparatus, and methods are provided below.
[0020] (III. Detailed Examples) 1-2 are perspective views of an exemplary cryogenic milling system 50 having a body 100 configured to removably receive a sample-containing container 200. Fig. 1(B) illustrates an example of a cryogenic milling system having a sample-containing container 200 disposed within an opening 101 of the body 100. Fig. 2 illustrates an example of a cryogenic milling system 50 having a sample-containing container 200 removed from the opening 101 of the body 100.
[0021] Figure 1(B) is a partial view of the sample containment vessel 200, with a portion of the outer wall (e.g., wall 202) removed to show an example of the blade configuration 204 inside the vessel 200. Note that two blades are shown in Figure 1(B), but the containment vessel 200 may alternatively have a single blade (e.g., as described below with respect to Figure 4B). In another example, the vessel may alternatively have more than two blades (e.g., three blades, four blades, five blades) in another exemplary configuration. The containment vessel 200 may be receivable within the body 100 via a series of tracks 112a and 112b configured to slidably receive the rails 210a and 210b of the sample containment vessel 200, for example. When the sample containment vessel 200 is slid into the body 100 as shown in Figure 1(A), the engagement lever 110 is rotated (e.g., in the direction F shown in Figure 1(A)), resulting in the containment vessel 200 being engaged with the opening 101 of the body 100 or being held within the opening 101 in a retainable manner. In one example, rotating the engagement lever 110 in the direction F may result in one or more pressing members (described in further detail below) pressing upward in the F direction (see Figure 1(A)), and the pressing members pressing upward, thus pressing the rails 210a and 210b against the respective tops of the tracks 112a and 112b of the body 100 to apply a clamping force to the sample containment vessel 200.
[0022] As described in more detail below, when a user slides the sample containing container 200 into the opening 101 of the main body 100 and the engagement lever 110 is rotated in a direction F, various connections (e.g., a cryogen source connection, an exhaust connection, and / or a temperature sensor or sensor electrical contacts) and / or a blade drive source connection are engaged such that the sample contained within the sample containing container 200 may be further processed by the cryogenic grinding system 50. The main body 100 may further include a display interface 102, which may be, for example, a display and a touch screen for controlling the cryogenic grinding system 50. In one example, the display interface 102 may be, for example, a display and a touch screen having a graphical user interface (GUI) including, for example, displayed buttons or other GUI interface elements that allow a user to control the cryogenic grinding system 50. The main body 100 may further include a stop button 108 that, when pressed, immediately stops the cryogenic grinding system. In one example, the stop button 108 may be an emergency stop button for stopping the system in the event of, for example, a malfunction or if the user operates the system incorrectly. The body 100 further includes a series of legs 106a-106c. In one example, any one or more of the legs 106a-106c may be a mass cell or any other type of mass sensor for determining the weight of the sample in the sample-containing container 200 and / or the weight of the cryogen provided to or contained within the sample-containing container 200. In the example shown in FIG. 1(A), the front leg 106a is shown as a mass cell. The mass cell may provide an output or resistance indicative of the weight or mass of any one or combination of the sample in the sample-containing container 200 and / or the weight of the cryogen provided to or contained within the sample-containing container 200.
[0023] As an alternative to the display interface described above and / or the automated and / or semi-automated controls described, the cryogenic grinding system 50 may instead be manually or analog controlled. For example, any one or combination of the amount of cryogen introduced into the vessel, the grinding duration of the at least one blade, or the grinding speed of the at least one blade may be controlled via any one or combination of switches, levers, or dials. Additionally, the system may provide feedback via any one or combination of indicator lights, LCD screen(s), and / or audible indicators.
[0024] 1(A) and 1(B), the sample containing container 200 may include, for example, a handle 208 and may have an outer wall 202. The sample containing container 200 may further include an inner wall (e.g., inner wall 252 of FIG. 4A ) and may comprise, for example, an insulating material, a gas, a fluid, or may be evacuated such that a vacuum exists between the outer wall 202 and the inner wall 252 to isolate a sample and / or cryogen provided in the sample containing container 200 from the surrounding environment.
[0025] 2, the sample containing container 200 may include a blade drive facility 216, which may be configured to be received by the blade drive opening 116 of the body 100 when the sample containing container 200 is slid into the opening 101 by a user. Additional details of the blade drive facility 216 are described in further detail below.
[0026] The sample-containing container 200 may further include a sample-dispensing opening having a handle 214. FIGS. 3A and 3B show views of a sample-containing container 200 that may be similar to the sample-containing container 200 shown in FIGS. 1-2. The handle 214 may be connected to a dispensing door 217, which may be pivotally connected to a lid 240 of the sample-containing container 200. As described above, the dispensing door 217 may be pivotally connected to the dispensing door 217 to allow a user to pivot the dispensing door 217 generally in a direction R (FIG. 3B) so that a sample may be dispensed into the sample-containing container 200. Once a sample has been dispensed into the sample-containing container 200, the dispensing door 217 may be closed. Placement of the sample-containing container 200 into the opening 101 of the body 100 and rotation of the engagement lever 110 may result in a downward or sealing force being applied to the dispensing door 217 and / or the handle 214. As mentioned above and described in more detail below, one or more clamp members may provide an upward force (e.g., in the direction P shown in FIG. 1(A)) on the tracks 112a and 112b. The above-mentioned upward force may cause the feed door 217 and / or handle 214 to be pressed against a corresponding surface in the blade drive opening 116, thus forcing the feed door 217 downward to seal, minimize, and / or prevent escape of gas, liquid, or sample disposed in the sample-containing container 200 during processing. Either or both of the feed door 217 and the feed opening of the sample-containing container 200 may have a gasket(s) or seal to further improve the sealing interface between the feed door 217 and the corresponding opening. The gasket(s) or seal may include any suitable sealing interface known in the art.
[0027] 3A and 3B show an example of a sample-containing vessel 200 removed from the body 1000. FIG. 4A and 4B show an example of a sample-containing vessel 200 having a top section 200a separated from a bottom section 200b. As shown in FIG. 3A and 3B, the sample-containing vessel 200 may further include a blade drive support portion 222 and a blade drive coupler 220 as part of the blade drive arrangement 216. As best shown in the cross-sectional views of FIG. 5(A) and FIG. 6(A), the blade drive support portion 222 may include, for example, one or more bearings or bushings for rotatably supporting the blade shaft 206. The blade drive coupler 220 may be connected or otherwise configured to provide a rotational force to the blade shaft 206, for example. The blade drive coupler 220 may include, for example, a series of engagement teeth as shown in FIG. 5(B), which may be configured to engage and rotate simultaneously with the drive coupler 120 of the body 100. As best shown in Figures 5(B) and 6(B), the blade drive coupler 220 and the drive coupler 120 may be configured to engagably couple when the engagement lever 110 is pulled by a user in direction F (Figure 1(A)), which causes the blade drive coupler 220 to move in direction P (Figure 5(B)). Figure 5(B) shows an example of the blade drive coupler 220 and the drive coupler 120 in a disengaged position (e.g., allowing for the installation or removal of a sample holding container 200 within the body 100). Figure 6(B) shows an example of the blade drive coupler 220 and the drive coupler 120 in an engaged position (e.g., transferring rotational force provided by a motor to the blade drive coupler 220). An example motor is shown in Figure 8 as reference numeral 172.
[0028] 3A and 3B show an example of an exhaust port 234 and a cryogen supply port 232. The cryogen supply port 232 may be configured to be placed in fluid communication with a cryogen supply of the body 100 (e.g., the cryogen supply 132 of FIG. 5(A), FIG. 6(A), and FIG. 7). As shown in the example of FIG. 3A and 3B, the cryogen supply port 232 may have a recess, for example, including an opening. The recess may improve the sealing surface area between the cryogen supply port 232 and the cryogen supply of the body 100, for example. Either or both of the cryogen supply port 232 and the cryogen supply 132 of FIG. 5(A), FIG. 6(A), and FIG. 7 may have a gasket(s) or seal to further improve the sealing interface between the cryogen supply port 232 and the cryogen supply 132. The gasket(s) or seal may include any suitable sealing interface known in the art. The cryogen supply port 232 and the cryogen supply 132 may be configured to be spaced apart from one another when the sample containing container 200 is initially slid into the body 100. When the sample containing container 200 is slid sufficiently into the body 100 and the engagement lever 110 is pulled in direction F, the cryogen supply port 232 and the cryogen supply 132 may be moved (e.g., in direction P) into engagement, providing a seal or partial seal and allowing fluid communication between the cryogen supply port 232 and the cryogen supply 132.
[0029] The exhaust port 234 of the sample-containing container 200 may be configured to be placed in fluid communication with an exhaust duct of the body 100 (e.g., exhaust duct 134 of FIG. 8). As shown in the example of FIGS. 3A and 3B, the exhaust port 234 may have a recess that includes an opening, for example. The recess may improve the sealing surface area between the exhaust port 234 and the exhaust duct interface of the body 100, for example. Either or both of the exhaust port 234 and the exhaust duct interface may have a gasket(s) or seal to further improve the sealing interface between the exhaust port 234 and the exhaust duct 134. The gasket(s) or seal may include any suitable sealing interface known in the art. The exhaust port 234 and the exhaust duct 134 may be configured to be spaced apart from each other when the sample-containing container 200 is initially slid into the body 100. When the sample container 200 is slid fully into the main body 100 and the engagement lever 110 is pulled in direction F, the exhaust port 234 and the exhaust duct 134 may be moved (e.g., in direction P) into engagement, providing a seal or partial seal and allowing fluid communication between the exhaust port 234 and the exhaust duct 134.
[0030] 4A and 4B show an example of a sample containing vessel 200 having a top section 200a separated from a bottom section 200b. The top section 200a may include, for example, a feed door 217 and a handle 214 optionally hinged thereto via a hinge 219. The top section 200a may further include a blade drive coupler 220 having a blade shaft 206 rotatably mounted to the top section 200a via one or more bearings and / or bushings, and a blade drive support portion 222. The blade drive support portion 222 may further include a seal, gasket, or O-ring configured to prevent leakage of fluid from the sample containing vessel 200 through an interface between the top section 200a and the rotatable blade shaft 206. In one example, the seal, gasket, or O-ring may be made of Teflon. TM(polytetrafluoroethylene). As shown in FIG. 4B, the blade shaft 206 may have one or more blades 204a connected thereto, for example. Note that while only a single blade is shown in FIG. 4B, any number of blades may be present as permitted by the spatial constraints of the sample-containing container 200. For example, as shown in the example of FIG. 1(B), the blade shaft 206 may instead have two blades mounted thereon. The blade or blades may be formed of a rigid material, such as steel or stainless steel, and may be hardened or otherwise treated to increase the strength or rigidity of the blade, particularly at the contacting leading edge 204c of the blade 204b. In one example, the leading edge 204c of the blade may be sharpened and / or may include a series of ridges or other patterned or randomized surface irregularities that may further improve the efficiency where the blade can debulk a sample. In some examples, the blades may be replaceably connected to the blade shaft 206, allowing a user to replace or otherwise repair the blade. In one example, the blade 204b may be threaded onto the shaft 206 or may be held to the shaft via a bolt threaded into the bottom of the blade shaft 206.
[0031] Top section 200a is configured to rest on bottom section 200b. Bottom section 200b may include an outer wall 202 and an inner wall 252, a handle 208, and a sealing channel or interface 233. In one embodiment, the sealing channel or interface may be configured to receive a seal, such as a gasket or an O-ring. In one example, top section 200a and bottom section 200b may be made of Teflon, e.g., in either or both of top section 200a and / or bottom section 200b. TM The top section 200a may have a top section seal 236, which may be made of Teflon (polytetrafluoroethylene) seals, gaskets, or O-rings. For example, the top section 200a may have a top section seal 236, which may be made of Teflon (polytetrafluoroethylene) seals, gaskets, or O-rings. TM(polytetrafluoroethylene) seals, gaskets or O-rings. The examples described include one or more Teflon™ gaskets, although it is noted that the gasket(s) or seals may include any suitable sealing interface known in the art.
[0032] As shown in FIG. 4C, the top section 200a may have a series of studs or protrusions 244 (FIG. 4C) configured to be received by corresponding receiving openings 235 in the bottom section 200b, for example, to align the top section 200a with the bottom section 200b. Placement of the sample containing container 200 within the opening 101 in the body 100 and rotation of the engagement lever 110 may result in a downward or sealing force being applied to the top section 200a and / or the bottom section 200b. As described above and in more detail below, one or more clamping members may provide an upward force (e.g., in the direction P shown in FIG. 1(A)) on the tracks 112a and 112b. The aforementioned upward force may result in the top section 200a being pressed against the bottom section 200b, thus pressing the top section 200a downward to seal, minimize and / or prevent the escape of gas, liquid or sample disposed within the sample-containing vessel 200 during processing. When the engagement 110 is rotated to the released position, the top section 200a may be separated from the bottom section 200b, for example, to remove the sample and / or to clean or reprocess and / or refurbish the sample-containing vessel 200.
[0033] It is further noted that although the stud or protrusion 244 is shown in FIG. 4C as being located on the top section 200a, the stud or protrusion 244 may instead be on the bottom section 200b and the receiving opening may alternatively be on the top section 200a. Additionally, other methods of aligning the top section 200a with the bottom section 200b may be implemented. For example, the top section 200a may have a cylindrically shaped protrusion configured to fit within an opening in the bottom section 200b, for example.
[0034] In another example, the bottom section 200b may further include a series of threaded fastener receiving openings (e.g., reference numeral 234 in FIG. 4A) in the flange 242. It is noted that although only three fastener receiving openings 235 are referenced in FIG. 4A for a total of twelve, any number of threaded fastener receiving openings may be implemented. The threaded fastener receiving openings may be configured and positioned on the flange 242 to align with corresponding through holes in the top section 200a. For example, the top section 200a may include a series of through holes positioned to align with the threaded fastener receiving openings in the bottom section 200b. To seal and secure the top section 200a to the bottom section 200b, a series of fasteners, such as bolts, may be passed through the series of through holes in the top section 200a and threaded into the fastener receiving openings in the bottom section 200b and appropriately tightened. The top section 200a may be separated from the bottom section 200b by reversing the process described above. The top section 200a may be separated from the bottom section 200b, for example, to add sample to the sample-containing vessel 200, to remove sample, and / or to clean or reprocess and / or refurbish the sample-containing vessel 200.
[0035] 7-9 show additional views of the body 100 of the exemplary cryogenic grinding system 50. FIG. 7 shows a cross-section of the example body 100 with the sample-containing container 200 removed. As described above, pulling the engagement lever 110 (FIGS. 1(A) and 2) in the direction F shown in FIG. 1(A) causes the container 200 to be engaged with or receivably retained within the opening 101 of the body 100. In one example, rotating the engagement lever may cause the engagement system to be actuated. For example, rotating the engagement lever 110 in the direction F may cause one or more pressing members to press upward in the direction P (see FIG. 1(A) and FIG. 7), which may press the rails 210a and 210b against the tops of the respective tracks 112a and 112b of the body 100 to apply a clamping force to the sample-containing container 200. The pushing member may comprise, for example, one or more cams 152 rotatably mounted on body 100. One or more cams 152 may have a cam profile with an increasing radius. The cam profile may be in contact with one or more slidably mounted force transfer members (e.g., force transfer member 182 shown in FIG. 2). Note that although only a single force transfer member 182 is labeled in FIG. 2, a similar or identical force transfer member (hidden from view) may be present within opening 101 on the opposite side of body 100. An increase in the cam profile radius may, for example, cause one or more slidably mounted force transition member(s) 182 to translate upward in direction P, thus causing the pushing member to push upward, pressing rails 210a and 210b (FIG. 2) against the tops of respective tracks 112a and 112b of body 100 to apply a clamping force to sample containing container 200, sealing top section 200a to bottom section 200b and / or sealing feed door 217 with flange 242. The steps described above may be reversed to release sample containing container 200 from body 100.For example, rotating the engagement lever 110 opposite direction F may cause one or more cams 152 to rotate in direction R such that a reduced radius portion of the cam contacts the force transfer member(s) 182, thus causing the force transfer member(s) 182 to retract in direction D, reducing or eliminating the upward force applied to the rails 210a and 210b. The retraction may cause the sample containing container 200 to move downward in direction D relative to the body 100, which may cause the blade drive coupler 220 to disengage from the drive coupler 120, the exhaust port 234 to be decoupled from the exhaust duct 134, and / or the cryogen supply port 232 to be decoupled from the cryogen supply 132. Once the blade drive coupler 120 is disengaged from the drive coupler 220, the exhaust port 234 is decoupled from the exhaust duct 134, and the cryogen supply port 232 is decoupled from the cryogen supply 132, the sample holder 200 may be slid out of the body 100, as shown in FIG. 2.
[0036] In addition to the features described above, the sample containing container 200 may include one or more thermistor or temperature sensor ports 299a (FIG. 5(A)) or 299b (FIG. 6(A)). In one example, the one or more thermistor or temperature sensor ports 299a and / or 299b may be configured to slidably receive one or more temperature sensors or thermistors. In the example shown in FIG. 6(A), two or more ports may be formed in the side of the sample-containing vessel 200 such that when the rails 210a and 210b of the sample-containing vessel 200 are slid into the body 100 via the tracks 112a and 112b and the engagement lever 110 is rotated as described above, one or more thermistors (e.g., thermistor 199) of the body 100 contact a surface of an inner wall (e.g., inner wall 252) of the sample-containing vessel 200 to form a thermal path between the inner wall 252 and thermistor 199, allowing the control system (described in more detail below) to determine the temperature within the sample-containing vessel 200. In one embodiment that can be used with or instead of the configuration described above, the sample-containing vessel 200 may have a thermistor opening 299b. The thermistor opening operates similarly to the configuration described above, but instead, the thermal contact between the thermistor and the inner wall of the sample-containing vessel 200 may occur at the bottom of the sample-containing vessel 200 instead.
[0037] In yet another embodiment, a thermistor or other temperature sensor or sensors may be part of the sample-containing vessel 200 (e.g., mounted on any interior wall of the sample-containing vessel 200), which may be used in place of or in combination with either or both of the configurations described above. The thermistor 199 mentioned above and shown in FIG. 6(A) may instead be an electrical contact portion that provides electrical contact between the body 100 and the thermistor or temperature sensor(s) of the sample-containing vessel 200.
[0038] As discussed above, the drive coupler 120 may be configured to rotate in at least one of two directions and may be configured to impart a rotational force to the blade(s) in the sample containing container 200 after being coupled to the blade drive coupler 220. The drive coupler 120 may be rotatably supported within the body 100 via a blade drive shaft 121. The blade drive shaft 121 may be rotatably supported via a bushing, a bearing, or a combination thereof. As best shown in FIG. 8, the drive shaft 121 may be mechanically or otherwise operably connected to a motor 172 of the body 100. Some examples of a mechanical or operable connection between the motor 172 and the blade drive shaft 121 may include a belt or chain drive, a gear train, or in an alternative configuration, the motor may be directly coupled to the blade drive shaft 121.
[0039] As shown in FIG. 8, the exhaust duct 134 may be in fluid communication with a blower or aerator 150. The aerator 150 may be configured to draw gas from the exhaust duct 134 and into an outlet opening 189. The outlet opening 189 may be configured to remain open to the surrounding atmosphere or may be configured to have an additional duct or tube connected thereto to exhaust fluids (e.g., gases) generated during processing of the samples contained within the sample-containing containers 200. The blower or aerator 150 may be any suitable electrically powered blower or fan known in the art. As described in more detail below, the blower or aerator may be powered or otherwise operated by a controller.
[0040] As best shown in FIG. 9, the cryogen supply 132 of the body 100 may be fluidly connected to a cryogen input 133. The cryogen input 133 may include an electronically or hydraulically controlled valve 135 for controlling the supply of cryogen to the cryogen supply port 232 of the sample container 200 via the cryogen supply 132. As described in more detail below, the electronically or hydraulically controlled valve 135 may be controlled or otherwise powered by a controller. The cryogen supply may be isolated, for example (e.g., via an isolation 136). The isolation 136 may prevent the accumulation of condensation due to the cryogen supply having a temperature lower than the dew point of the surrounding environment. Note that although only partial isolation is shown in FIG. 9 to prevent obstruction of visibility, the entire cryogen conduit / pipe may be isolated. The cryogen input 133 may be configured to be connected to a cryogen source, such as, for example, a liquid nitrogen source. The cryogen input 133 may be, for example, a standard connector (eg, a National Pipe Taper Thread "NPT" type 3 / 8 connector).
[0041] 10 illustrates an example of a controller or control structure that can be used in the present disclosure. By way of example, the controller may include, for example, a liquid source control component, a motor control component, and a blade control component. The controller may be in signal communication with, for example, any one or combination of mass sensor(s) 910, temperature sensor(s) 912, blower 950, motor 914, and / or valve 916. In one example, the mass sensor(s) 910 may be similar to mass sensor or mass cell 106a (FIGS. 1(A), 2, 5(A), 6(A), 7, 8, and 9), the temperature sensor(s) 912 may be similar to thermistor 199 (FIG. 6(A)), the blower 950 may be similar to blower or aerator 150 (FIGS. 5(A), 6(A), 7, 8, and 9), the motor 914 may be similar to motor 172 (FIG. 8), and the valve 916 may be similar to electronically or hydraulically controlled valve 135 (FIG. 9).
[0042] In one example operation of the controller, it is determined that once a sample is placed in the sample-containing container 200, the sample-containing container 200 is placed in the body 100. A user may indicate that the sample is to be processed via the display interface 102. For example, the display interface 102 may have a graphical user interface (GUI) with, for example, an icon or other visual indicator, and the controller may determine that the user has touched or pressed the icon or other visual indicator, signifying that the user wishes to process the sample. It is noted that throughout this disclosure, the GUI is referred to as both providing indicators to the user and allowing the user to control or input the device, although in another embodiment the user may provide instructions via a switch knob. Additionally, instead of a screen, lights or other indicators may be used to indicate the status of the device to the user.
[0043] Once it is determined that the container is placed in the body 100 and the engagement lever 110 is rotated to the locked position, the controller may provide a current or signal to the valve 916 to supply cryogen to the sample containing container 200. In one example, the user may input any one or combination of weight, volume, or type of sample present in the sample containing container 200, and the controller determines the volume of cryogen to be supplied to the sample containing container 200 based on any one or combination of weight, volume, or type of sample input by the user. In another example, the controller may determine the weight of the sample placed in the sample containing container 200 based on the output from the mass sensor(s) 910, and may automatically supply an appropriate amount of cryogen and / or suggest an appropriate amount of cryogen to the container via the display interface 102. The GUI may then be controlled to request confirmation from the user and / or an override option may be provided to allow the user to add or subtract a volume of cryogen from the suggested amount. In yet another example, the system may automatically supply a set volume of cryogen when the user indicates that the sample is to be processed. In any one or combination of the foregoing examples, the initial volume of cryogen may be between 70 and 300 milliliters (ml). In yet another example, the initial volume of cryogen may be between 100 and 150 ml. In one preferred embodiment, the initial volume of cryogen may be between 140 and 150 ml. In yet another preferred embodiment, the initial volume of cryogen may be between 185 and 210 ml. In one example, the controller may set the initial volume of cryogen provided to the sample containing container 200 via the valve 916 to approximately 200 ml. In one example, the controller may use an output from the mass sensor(s) to determine when to open / close the valve 916 when the appropriate volume of cryogen has been added to the sample containing container 200.
[0044] In one exemplary operation of the controller usable in the above-described embodiment, when an appropriate amount of cryogen, or more preferably said cryogen, has been added to the sample-containing container 200, the controller may operate the motor 914 to rotate the blade(s) (e.g., blade 204(b) of FIG. 4B and / or blade 204a of FIG. 1(B)). In one preferred example, the blade may be controlled to rotate in a first direction and then in a second opposite direction in a "pulsed" motion as the cryogen is added to the sample-containing container 200. Alternating the direction of the blade as described above may result in more uniform treatment of the sample with the cryogen and may reduce sample sticking to the blade. Once the desired amount of cryogen has been added, the controller may pause the rotation of the blade to allow the cryogen to remove heat from the sample and reduce the temperature of the sample to the desired temperature. The controller may determine whether the temperature of the sample has been reduced to the desired temperature by monitoring the output of the temperature sensor(s) 912. Once the controller determines that the temperature of the sample has decreased to the desired temperature, the motor may be powered again to grind or otherwise reduce the particle size of the sample in the sample containing container 200. In one example, the GUI displayed on the display interface 102 may indicate the temperature of the sample in the sample containing container 200. In one embodiment, the GUI may include an indicator or section that allows the user to either override the desired temperature of the sample and / or set the desired temperature before the motor is again controlled to rotate the blades to cause further grinding or particle size reduction of the sample.
[0045] In one example, the temperature of the sample in the sample-containing container 200 may be continuously monitored. In the example described above, upper and lower temperature limits may be set, and the controller may supply additional cryogen if the temperature of the sample in the sample-containing container 200 does not rise above or fall below the threshold temperature. In one example, the cryogen may be liquid nitrogen, which has a boiling point of approximately -198 degrees Celsius, and the threshold temperature may be any value between -50 and -198 degrees Celsius. In another example, the threshold temperature may be any value between -100 and -170 degrees Celsius. In one preferred example, the threshold temperature may be -140 degrees Celsius. Thus, in the example described above, if the controller determines that the temperature of the sample in the sample-containing container 200 exceeds -140 degrees Celsius, the valve 916 is controlled to supply additional liquid nitrogen to the sample-containing container 200 until it is determined that the temperature has decreased to at least 140 degrees Celsius. It is noted that while the example described above provides advantages, any temperature or range of temperatures (particularly within the ranges described above) may serve as the threshold temperature.
[0046] In any of the examples described above, the controller may further control the blower(s) 950. The blower may be controlled to remove gas that accumulates within the sample-containing container 200, for example, as the cryogen boils. In some examples, the controller may turn on the blower whenever cryogen is present within the sample-containing container 200. In another example, the controller may turn on the blower when it is determined that the temperature within the sample-containing container 200 has fallen below a certain temperature. For example, if a desired or optimal temperature range for the sample is set or provided, the blower may be turned on when the temperature of the sample within the sample-containing container 200 approaches or falls below the desired temperature range.
[0047] In another example, the motor speed, and therefore the blade speed, may be controlled based on any one or combination of the above-mentioned determinations. For example, the blade speed may be controlled to be slower when the detected temperature is above a threshold temperature and then controlled to increase as the temperature drops below the threshold temperature. In another example, the blade speed may be controlled to be slower for a first period of time after a user indicates that the sample in the sample-containing container 200 should be processed and then controlled to increase to a higher speed for a second period of time after the first period of time.
[0048] It is noted that the operations described above are provided by way of example, and although some specific examples have been given, those skilled in the art will appreciate that further possibilities for automation, semi-automation, or manual control of the disclosed cryogenic grinding apparatus systems and devices will fall within the scope of this disclosure after comprehending the disclosure provided herein.
[0049] In some implementations, as part of or incorporating various functions and methods described herein, one or more microcontrollers may be implemented (e.g., in any one or combination of the controller 902, the liquid source controller 904, the motor controller 906, and / or the blower controller 908) to perform various operations in accordance with aspects of the present invention.

[0052] A timer 1112 may record and / or calculate the amount of time between events occurring within the controller 1100, count the number of events, and generate the baud rate for communication transfers. A BUS controller 1114 may prioritize BUS usage within the controller 1100. An ADC 1118 may enable the controller 1100 to send pulses to signal other devices.
