Description

Technical Field

[0001] This document discloses an allocation unit according to the appended claims. Background Technology

[0002] On farms, it is sometimes desirable to analyze milk samples from specific animals using milk analysis equipment. This may be to investigate whether the animal suffers from mastitis, ketosis, ureaemia, or other diseases or conditions that could affect milk yield and / or milk quality; or to measure parameters that reflect milk quality itself, such as the percentages of fat, protein, lactose, etc.

[0003] One convenient way to extract milk samples is to milk the animals at a milking station (e.g., via a milking robot) or in a rotary milking parlor. A milk sampling device can then extract a milk sample from the milk line containing the animal's milk and provide the sample to a milk analysis instrument.

[0004] Depending on the type of test to be performed, the milk analyzer may need to mix the milk with one or more other liquids before providing the milk sample to the analyzer to optimally prepare the milk sample for testing. For example, the milk may have to be diluted with a diluent or prepared with a chemical indicator.

[0005] It is desirable to prevent contamination of milk samples by dirt or other unwanted particles, as this could affect analytical results. It is also desirable that the proportions between the milk fraction and other liquid fractions be precise, as these proportions play a crucial role, for example, in calculating the somatic cell count (SCC) of the milk fraction of a milk sample. Furthermore, it is desirable to automate the sampling / testing process as much as possible, thereby avoiding or preferably eliminating potential sources of failure during mixing and human interaction, thus saving farmers' work. It must also be ensured that, under no circumstances, the liquids / chemicals used by the milk analysis instruments reach the milk pipeline.

[0006] The aim is to develop a concept for preparing milk samples for analysis through further exploration and development. Summary of the Invention

[0007] Therefore, the objective of this invention is to solve at least some of the problems mentioned above and to facilitate the preparation of milk samples for milk sample analysis.

[0008] According to a first aspect of the invention, this objective is achieved by a dispensing unit. This dispensing unit is designed to provide a milk mixture comprising milk and liquid to a milk analysis device. The milk analysis device thereby receives and enables it to analyze the milk mixture / milk sample. The analysis may, for example, include somatic cell count (SCC), standard plate count (SPC), conductivity, antibody detection for one or more diseases, milk pregnancy test, preliminary incubation count (PIC), laboratory pasteurization count (LPC), coliform count, and / or Gerber test (for determining milk fat).

[0009] The dispensing unit includes a first section, which in turn includes a first elongated block having a first side extending in a substantially horizontal plane. The first section also includes a mixing cavity formed in the first elongated block, wherein the mixing cavity opens toward the first side of the first elongated block.

[0010] Additionally, the first section includes a first fluid port formed in the first elongated block. Furthermore, the first section includes a first groove formed in the first elongated block. The first groove extends from the first fluid port to the mixing chamber, wherein the first groove opens toward a first side of the first elongated block.

[0011] The first section also includes a second fluid port formed in the first elongation block.

[0012] The first section also includes a second groove. The second groove is formed in the first elongated block. The second groove extends from the second fluid port to the mixing chamber. The second groove opens toward a first side of the first elongated block.

[0013] The first section also includes a first fluid outlet formed in the first elongated block. Furthermore, the first section includes a third groove formed in the first elongated block, wherein the third groove extends from the mixing chamber to the first fluid outlet, and wherein the third groove opens toward a first side of the first elongated block.

[0014] The distribution unit further includes a second section. The second section includes a second elongated block having a second side extending in a substantially horizontal plane.

[0015] When the first side of the first piece is adjacent to the second side of the second piece in the assembled state, a first conduit is formed by enclosing the open side of the first groove. A second conduit is formed by enclosing the open side of the second groove. A third conduit is formed by enclosing the open side of the third groove. Furthermore, a closed mixing chamber is formed by enclosing the open side of the mixing chamber.

[0016] Therefore, a dispensing unit is provided for receiving milk and at least one other liquid, mixing the milk and other liquid in an appropriate ratio to form a milk mixture, and also supplying the milk mixture to a milk analysis device for analysis. The provided dispensing unit is reliable and has a compact design. Furthermore, the dispensing unit has minimal angles, corners, and gaps where dirt and / or milk residue may remain. This facilitates cleaning and reduces the risk of carryover effects between milk samples.

[0017] Optionally, the second extension block of the dispensing unit may include an extension recess. The extension recess may extend substantially over a second side surface of the second extension block. The extension recess is operable to receive and retain a sealing device.

[0018] By applying a sealing device in the recess of the second elongated block, the conduit and mixing chamber formed between the first and second elongated blocks are effectively enclosed. The continuous sheet is effectively held in place by the elongated recess, which facilitates the correct installation of the sealing device and eliminates the risk of misplacement of the sealing device during operation. This prevents and avoids leakage of the milk / liquid / milk mixture.

[0019] Optionally, the sealing device can be a continuous sheet.

[0020] The seal provided by a sealing device in the form of a continuous sheet is superior to the seal performance of a gasket that conforms to the shape of the groove and mixing cavity in the first elongated block. This avoids or at least reduces errors during the installation and / or replacement of the sealing device.

[0021] Optionally, the mixing chamber and recess of the dispensing unit may be surrounded by a corresponding edge. This edge may define the edge of the corresponding chamber and recess, extending in a direction perpendicular to the first side surface of the first elongated block.

[0022] When the first and second sections are in the assembled state, the corresponding edges, together with the sealing device of the second elongated block, can form a seal on the corresponding conduit and the closed mixing chamber.

[0023] Especially when used in conjunction with a sealing device, the edge will engage with the flexible sealing device, thus providing an effective seal to the formed conduit / mixing chamber. This further reduces the risk of leakage of milk / liquid / milk mixture.

[0024] Optionally, the first and second sections of the dispensing unit can be releasably assembled in an assembled state by at least one retaining component, thereby enabling the replacement of the sealing device.

[0025] Furthermore, the releasable assembly facilitates the replacement or repair of any other components of the dispensing unit; or cleaning.

[0026] Optionally, the mixing chamber may include a stirring member that can be configured to rotate within the mixing chamber.

[0027] Milk and liquids are mixed conveniently and efficiently by the rotational movement of the stirring element within the mixing chamber. Good mixing is a prerequisite for reliable milk analysis of the milk mixture by a milk analysis device.

[0028] Optionally, the stirring component may include a magnet that can be configured to rotate within the mixing chamber when subjected to an external magnetic field.

[0029] Because of the magnetic form of the stirring element, rotation of the stirring element can be achieved without any rotating mechanism or, for example, an axis around which the stirring element rotates. This avoids the cleaning problems and possible repair or maintenance associated with such mechanisms. The external magnetic field can be generated, for example, by an electric motor outside the mixing chamber. In the event of repair / maintenance requirements for the external electric motor, it can be easily replaced with a replacement motor during repairs without affecting milk production.

[0030] Optionally, the agitator may be covered with a protective coating.

[0031] For example, protective coatings in the form of plastic or rubber can protect the magnetic stirring components from the effects of milk / liquids without damaging the inner walls of the mixing chamber. This extends the technical lifespan of the stirring components.

[0032] Optionally, the dispensing unit may include a first valve device. The first section may include a third fluid port formed in the first extension block. The first section may also include a fourth fluid port formed in the first extension block. Furthermore, the first section may include a second fluid outlet formed in the first extension block, a fifth fluid port formed in the first extension block, and a sixth fluid port also formed in the first extension block. The first section may additionally include a seventh fluid port formed in the first extension block, wherein the seventh fluid port is arranged to receive milk, and a first connecting pipe releasably connected to the fifth fluid port and also to the sixth fluid port.

[0033] The first section may further include a fourth groove formed in the first elongated block, extending from the third fluid port to the second fluid outlet, wherein the fourth groove opens toward a first side of the first elongated block. The first section may also include a fifth groove formed in the first elongated block, extending from the fourth fluid port to the fifth fluid port, wherein the fifth groove opens toward a first side of the first elongated block. Additionally, the first section may include a sixth groove formed in the first elongated block, extending from the sixth fluid port to the seventh fluid port, wherein the sixth groove opens toward a first side of the first elongated block.

[0034] The first valve device can be connected to the third fluid port, the fourth fluid port, and the first fluid port. When the first section and the second section are in the assembled state, the following can occur: a fourth conduit can be formed by enclosing the open side of the fourth groove; a fifth conduit can be formed by enclosing the open side of the fifth groove; and a sixth conduit can be formed by enclosing the open side of the sixth groove.

[0035] The first valve device can be controlled between two modes: a first mode connecting the fifth conduit to the fourth conduit; and a second mode connecting the fifth conduit to the first conduit.

[0036] By introducing a first valve device, such as a three-way valve, into the dispensing unit, the amount of milk dispensed into the mixing chamber can be controlled in a detailed and precise manner, thereby improving the milk analysis results of the milk analyzer.

[0037] Optionally, the dispensing unit may include a second valve device.

[0040] The second valve device can be connected to the eighth fluid port, the ninth fluid port, and the second fluid port. When the first and second sections are in the assembled state: the seventh conduit can be formed by enclosing the open side of the seventh groove. Additionally, the eighth conduit can be formed by enclosing the open side of the eighth groove.

[0041] The second valve device can be controlled between two modes: a first mode connecting the seventh conduit to the eighth conduit; and a second mode connecting the eighth conduit to the second conduit.

[0042] By introducing a second valve device, such as a three-way valve, into the dispensing unit, the amount of liquid dispensed into the mixing chamber can be controlled in a detailed and precise manner, thereby improving the milk analysis results of the milk analysis device.

[0043] Optionally, the dispensing unit may include a third valve device. The first section may include a twelfth fluid port, a thirteenth fluid port, a fourteenth fluid port, and a fifteenth fluid port formed in the first extension block.

[0044] The first section may further include a second connecting pipe capable of being releasably connected to the eleventh fluid port and also to the twelfth fluid port. The first section may also include a pump capable of being connected to the fifteenth fluid port.

[0045] The first section may include a ninth groove formed in the first elongated block, extending from the twelfth fluid port to the thirteenth fluid port, wherein the ninth groove is open toward a first side of the first elongated block. The first section may also include a tenth groove formed in the first elongated block, extending from the fourteenth fluid port to the fifteenth fluid port.

[0046] The tenth recess can open toward the first side of the first elongated block. The third valve device can be connected to the thirteenth fluid port and the fourteenth fluid port.

[0047] When the first and second sections are assembled, the ninth conduit can be formed by enclosing the open side of the ninth groove, and the tenth conduit can be formed by enclosing the open side of the tenth groove. The third valve device can control between two modes: a first mode connecting the ninth and tenth conduits; and a second mode disconnecting the ninth and tenth conduits.

[0048] By introducing a third valve device into the dispensing unit, the amount of liquid and / or milk dispensed into the mixing chamber can be controlled in a detailed and precise manner via a connected pump, resulting in improved accuracy of the composition of the milk mixture. This also improves the results of milk analysis performed by the milk analysis device.

[0049] Optionally, the dispensing unit includes a fourth valve device. Additionally, the first section may include a sixteenth fluid port, a seventeenth fluid port, and an eighteenth fluid port formed in the first elongation block. The eighteenth fluid port is connectable to a second liquid container.

[0050] The first section may further include a nineteenth fluid port formed in the first elongation block. The nineteenth fluid port is connectable to a pump. The first section may include an eleventh recess formed in the first elongation block, extending from the sixteenth fluid port to the eighteenth fluid port. The eleventh recess may open toward a first side of the first elongation block.

[0051] The first section may further include a twelfth groove formed in the first elongated block, extending from the seventeenth fluid port to the nineteenth fluid port, wherein the twelfth groove is open toward a first side of the first elongated block.

[0052] The fourth valve device can be connected to the sixteenth fluid port and the seventeenth fluid port.

[0053] When the first and second sections are assembled, the eleventh conduit can be formed by enclosing the open side of the eleventh groove. Similarly, the twelfth conduit can be formed by enclosing the open side of the twelfth groove. The fourth valve device can be adjusted between two modes: a first mode connecting the eleventh and twelfth conduits; and a second mode disconnecting the eleventh and twelfth conduits.

[0054] By introducing a fourth valve device into the dispensing unit, the amount of liquid and / or milk dispensed into the mixing chamber can be controlled in a detailed and precise manner via a connected pump, thereby improving the accuracy of the milk mixture composition. This also improves the results of milk analysis performed by the milk analysis device.

[0055] Optionally, the dispensing unit includes a fifth valve device. The first section may also include a twentieth fluid port formed in the first elongation block, a twenty-first fluid port formed in the first elongation block, and a thirteenth groove formed in the first elongation block extending from the twentieth fluid port to the tenth groove. The thirteenth groove may open toward a first side of the first elongation block.

[0056] The first section may also include a fourteenth groove formed in the first elongated block, extending from the twenty-first fluid port to the sixth groove. The fourteenth groove may open toward a first side of the first elongated block.

[0057] The fifth valve device can be connected to the twentieth fluid port and the twenty-first fluid port.

[0058] When the first and second sections are in an assembled state, the thirteenth catheter can be formed by encapsulating the open side of the thirteenth groove, and the fourteenth catheter can be formed by encapsulating the open side of the fourteenth groove.

[0059] The fifth valve device can be adjusted between two modes: a first mode connecting the thirteenth catheter to the fourteenth catheter; and a second mode disconnecting the thirteenth catheter from the fourteenth catheter.

[0060] By introducing a fifth valve device into the dispensing unit, the amount of liquid and / or milk dispensed into the mixing chamber can be controlled in a detailed and precise manner via a connected pump, thereby improving the accuracy of the milk mixture's composition. This also improves the results of milk analysis performed by the milk analysis device.

[0061] Optionally, the first section may include a second-second fluid port formed in the first elongated block and a fifteenth groove formed in the first elongated block extending from the mixing chamber to the second-second fluid port. The fifteenth groove may open toward a first side of the first elongated block.

[0062] When the first and second sections are in the assembled state, the fifteenth conduit can be formed by encapsulating the open side of the fifteenth groove.

[0063] Due to the provided fifteenth conduit and twenty-second fluid port, excess milk mixture can be discharged from the mixing chamber into waste liquid without passing through the milk analysis device.

[0064] Optionally, when the first side of the first block is adjacent to the second side of the second block in the assembled state, the first section and the second section form a liquid distribution manifold.

[0065] Optionally, the liquid in the milk mixture can be a first liquid supplied from a first liquid container.

[0066] Optionally, the liquid in the milk mixture may be a second liquid supplied from a second liquid container.

[0067] Optionally, the liquid may include any one or any combination of dyeing liquid, diluent and / or saline solution.

[0068] Optionally, the liquid in the milk mixture can be a first liquid supplied from a first liquid container and a second liquid supplied from a second liquid container.

[0069] Optionally, the second liquid may include water, deionized water, water mixed with preservatives, acids, cations and / or anions, saline solution, citric acid solution, phosphoric acid, acetic acid, or similar liquids.

[0070] Optionally, the first liquid may include a staining agent that is capable of staining the cell nucleus.

[0071] The first liquid / staining agent is quite expensive. Furthermore, due to the staining power, fluorescence ability, and / or potential toxicity of the staining agent, it may be necessary to handle it with extreme care; that is, it must be handled with exceptional care during milk analysis. From an environmental / working environment perspective, it may be desirable to minimize or at least reduce the amount of staining agent used while still achieving reliable results in milk analysis.

[0072] By diluting the milk mixture with a second liquid, costs and environmental impact are reduced, while reliable results for milk analysis are achieved.

[0073] Other advantages and additional novel features will become apparent in the following detailed description. Attached Figure Description

[0082] The embodiments of the invention described herein are defined as a distribution unit that can be put into practice in the embodiments described below. However, these embodiments can be illustrated and implemented in many different forms and are not limited to the examples set forth herein; rather, these illustrative examples of embodiments are provided to make this disclosure thorough and complete.

[0083] Other objects and features may become apparent from the following detailed description taken in conjunction with the accompanying drawings. However, it should be understood that the drawings are for illustrative purposes only and are not intended to limit the embodiments disclosed herein, for which reference may be made to the appended claims. Furthermore, unless otherwise stated, the drawings are not necessarily drawn to scale and are merely illustrative of the structures and procedures described herein.

[0084] Figure 1ASystem 100 is illustrated in a scenario where a milk sample is extracted from a milk pipeline containing milk. The milk is extracted from an animal. This animal may be included in a herd of animals used for dairy farming on a farm. System 100 may advantageously (but not necessarily) be implemented in an automated milking facility (such as a milking robot), a rotary milking parlor, or a similar arrangement. System 100 may alternatively be used in a rotary milking parlor during manual milking.

[0085] "Animal" can refer to any type of domesticated female mammal, such as cow, goat, sheep, camel, horse, dairy cow, donkey, yak, etc.

[0086] System 100 can be configured to coordinate the extraction of milk samples from animals via milk sampling device 101 during regular milking. Milk sampling device 101 can be configured to extract milk samples from a milk line containing milk, i.e., milk that has been extracted from an individual animal during the milking process. The extracted milk sample can be, for example, a few centiliters or a few milliliters.

[0087] The purpose of milk sample extraction is to analyze the milk sample or a portion thereof in the milk analyzer 140. The milk analyzer 140 can be configured to receive milk samples and perform analyses on the received milk samples, such as those concerning mastitis, ketosis, somatic cell counts, etc.

[0088] To prevent any impurities (such as dirt, hair, bedding / feed clumps, and other particles) in the extracted milk from being transferred to the milk analyzer 140, the system 100 may include a filter device. The filter device may be arranged between the milk sampling device 101 and the milk analyzer 140, preferably closer to the milk sampling device 101 than to the milk analyzer 140, so as to prevent impurities from entering as much of the tubing involved as possible.

[0089] The extracted milk can be transferred to the distribution unit 110 by pump 113 via fluid connection line 114.

[0090] In different implementations, pump 113 may be, for example, a peristaltic pump, a hose pump, a roller pump, a tubular pump, or a similar arrangement.

[0091] The fluid connection line 114, and possibly other tubing in system 100, may include resilient flexible hoses comprising or made of, for example, plastics (e.g., nylon, polyurethane, polyethylene, polyvinyl chloride (PVC)); or synthetic or natural rubber. The fluid connection line 114 may have a substantially circular cross-section. The inner diameter of the fluid connection line 114 may be, for example, between 1 mm and 5 mm, preferably about 2 mm to 3 mm.

[0092] The dispensing unit 110 is a physical entity containing milk and at least one liquid milk mixture mixed in a controlled manner. The properly prepared milk mixture is then provided to the milk analysis device 140.

[0093] The distribution unit 110 includes a first segment 201 and a second segment 202. The first segment includes a first elongated block 210 having a first side 211 extending in a substantially horizontal plane, and the second segment includes a second elongated block 220 having a second side 222 extending in a substantially horizontal plane. Figure 2 exemplified in .

[0094] This allows the first section 201 and the second section 202 to be installed in an assembled state, wherein the first side 211 of the first block 210 is adjacent to the second side 222 of the second block 220.

[0095] When the first side 211 of the first block 210 is adjacent to the second side 222 of the second block 220 in the assembled state, the first section 201 and the second section 202 can form a liquid distribution manifold.

[0096] The first section 201 includes a mixing chamber 120 formed in the first elongation block 210. The mixing chamber 120 opens toward a first side 211 of the first elongation block 210. The first section 201 also includes a first fluid port 155 formed in the first elongation block 210. A fluid connection line 114 can be installed to the first fluid port 155 to enable the reception of milk extracted from animals.

[0097] The first section 201 includes a first groove 121 formed in the first elongation block 210. The first groove 121 extends from the first fluid port 155 to the mixing chamber 120. The first groove 121 opens toward a first side 211 of the first elongation block 210.

[0098] The first section 201 further includes a second fluid port 156 formed in the first elongation block 210. The second fluid port 156 can be connected to the liquid container 130. This allows the dispensing unit 110 to receive liquid contained in the liquid container 130. The liquid container 130 may contain liquid to be mixed with milk. The liquid may include any one or any combination of dye liquid, diluent, and / or saline solution.

[0099] Additionally, the first section 201 includes a second groove 122 formed in the first elongation block 210. The second groove 122 extends from the second fluid port 156 to the mixing chamber 120. The second groove 122 opens toward the first side 211 of the first elongation block 210.

[0100] When the first section 201 / first block 210 and the second section 202 / second block 220 are assembled, a closed mixing chamber is formed by enclosing the open side of the mixing chamber 120. Additionally, a first conduit is formed by enclosing the open side of the first groove 121, and a second conduit is formed by enclosing the open side of the second groove 122. Thus, milk and liquid can be received in the closed mixing chamber in appropriate proportions.

[0101] In some embodiments, the second conduit formed based on the second groove 122 may include a one-way valve 113 configured to prevent the milk mixture in the mixing chamber 120 from returning to the liquid container 130.

[0102] The first section 201 also includes a first fluid outlet 141 formed in the first elongation block 210. The first fluid outlet 141 is connectable to the milk analyzer 140 via a liquid connection pipe. A third groove 142 is formed in the first elongation block 210, wherein the third groove 142 extends from the mixing chamber 120 to the first fluid outlet 141. The third groove 142 opens toward a first side 211 of the first elongation block 210.

[0103] Therefore, when the first section 201 / first block 210 and the second section 202 / second block 220 are installed in an assembled state, a third conduit is formed by enclosing the open side of the third groove 142. A milk mixture containing milk and liquid can be supplied from a closed mixing chamber to the milk analyzer 140 via the third conduit, the first fluid outlet 141, and the liquid connection tubing. This enables the milk analyzer 140 to perform analysis of the supplied milk mixture.

[0104] Figure 1A An embodiment of the system 100 illustrated may further include a first liquid sensor 115 and / or a second liquid sensor 116. This enables the respective liquid sensors 115, 116 to detect the presence of air bubbles and / or liquid in the fluid connection line 114 and / or other tubing used for transferring milk / liquid and / or milk mixtures.

[0105] The first liquid sensor 115 and / or the second liquid sensor 116 may, for example, include a bubble detector arranged to be clamped onto the fluid connection line 114 and / or other tubing. Based on ultrasonic detection using the bubble detector, bubbles can be detected in the fluid connection line 114 and / or other tubing. This enables non-invasive, contamination-free liquid flow / monitoring.

[0106] The first liquid sensor 115 and / or the second liquid sensor 116 may alternatively include, for example, an optical sensor, which may be combined with a suitably arranged light source to enable the detection of changes in the detected light level caused by bubbles that scatter / block the light from the light source. For example, the light source may be placed on one side of the fluid connection line 114 and / or other tubing, while the optical sensor is on the other side.

[0107] Other possible alternatives to the optional first liquid sensor 115 and / or second liquid sensor 116 may be capacitive sensors, conductivity sensors, pressure sensors, flow meters, etc.

[0108] System 100 may also include components for regulation (i.e., allowing / disallowing the passage of the milk mixture), such as valves or pumps; specifically, a second pump 117. The second pump 117 may be configured to transfer the milk mixture in the milk analyzer 140 to waste liquid 150, for example, after milk analysis has been performed on the milk mixture. The second pump 117 may also be configured to retain the received milk mixture in the milk analyzer 140 by preventing the milk mixture from being transferred to waste liquid 150.

[0109] The advantage of using a pump instead of a valve is that the pump can provide very precise control over the flow of the milk mixture. Additionally, the pump can operate in both directions, which in turn makes it possible to clean / flush the fluid connection lines involved.

[0110] In different implementations, the second pump 117 may be, for example, a peristaltic pump, a hose pump, a roller pump, a tubular pump, or a similar arrangement.

[0111] Figure 1B The implementation scenario, including system 100, is also illustrated, which has the same characteristics as... Figure 1A The embodiments illustrated herein have similar purposes and also share at least some common technical features, such as, for example, a milk sampling device 101, a dispensing unit 110, a milk analysis device 140, a first section 201, a first elongated block 210 having a first side 211, a mixing chamber 120, a first fluid port 155, a first groove 121, a second fluid port 156, a second groove 122, a first fluid outlet 141, a third groove 142, a second section 202, a second elongated block 220 having a second side 222, and a first conduit, a second conduit, and a third conduit formed when the first side 211 of the first block 210 is adjacent to the second side 222 of the second block 220 in the assembled state.

[0112] The mixing chamber / mixing cavity 120 may include a stirring member 125, which may be configured to rotate within the mixing chamber when the dispensing unit 110 is in the assembled state. The stirring member 125 may include a magnet, which may be configured to rotate within the mixing chamber 120 when subjected to an external magnetic field.

[0113] External magnetic fields can be caused by, for example, rotating permanent magnets or electromagnetic fields.

[0114] In some implementations, the stirring member 125 may be covered with a protective coating, such as rubber, plastic or the like.

[0115] The liquid mixed with the extracted milk in the milk mixture can be a first liquid supplied from a first liquid container 130; and / or a second liquid supplied from a second liquid container 167. In some embodiments, the liquid may include any one or any combination of a dye liquid, a diluent, and / or a saline solution.

[0116] In some embodiments, the liquid in the milk mixture may include both a first liquid supplied from a first liquid container 130 and a second liquid supplied from a second liquid container 167.

[0117] The first liquid may then include a staining agent that enables the staining agent to stain the cell nucleus. The staining agent or staining liquid may alternatively be referred to as a reagent or (fluorescent) dye. Some non-limiting examples of staining agents may be trypan blue, methylene blue, pyronin γ-methyl green, propidium iodide, and safranin.

[0118] Somatic cell counts (SCCs) are made possible by staining the nuclei of cells in a milk mixture with a dye. SCC is a measure of the number of somatic cells present in milk (primarily white blood cells and possibly epithelial cells). SCC is frequently used as an indicator of milk quality and animal health. High SCC is often associated with mastitis, an inflammation of the mammary glands usually caused by infection.

[0119] Due to the staining effect of the dye, the somatic cells in the milk sample can then be counted, for example, manually by counting the number of stained cells, or by taking a photograph and analyzing the image using an image detection computer program. Another possibility is electronic counting, where the milk sample is stained with the dye and then passed through a flow chamber. As the stained cells pass through the laser beam, they scatter light and fluoresce, making it possible to count the stained cells.

[0120] After SCC is determined, the results can be compared to a threshold (e.g., 200,000 cells / ml). In some countries, there are legal limits on SCC in milk intended for human consumption (greater than 400,000 cells / ml in the European Union (EU)) because high counts can affect milk quality, shelf life, and suitability for certain processed products such as cheese.

[0121] Regular monitoring of SCC (Self-Concentration Calibration) is crucial for farmers to ensure the health of their herds and the quality of the milk produced. Sometimes, low SCC can be rewarded by dairy processors who purchase the milk with a bonus at the time of payment (and / or payments can be reduced for high SCC) to incentivize and promote high milk quality on the farm.

[0122] The second liquid may include water, deionized water, water mixed with preservatives, acids, cations and / or anions, saline solutions, citric acid solutions, phosphoric acid, acetic acid, or similar liquids.

[0123] The first liquid / staining agent is quite expensive. Furthermore, due to the staining power, fluorescence ability, and / or potential toxicity of the staining agent, it may be necessary to handle it with extreme care; that is, it must be handled with extra care throughout the process. From an environmental / working environment perspective, it may be desirable to minimize or at least reduce the amount of staining agent used while achieving reliable results in milk analysis.

[0124] Therefore, it may be desirable to dilute the milk mixture with a second liquid, thereby reducing costs and environmental impact while achieving reliable results.
