[0012] According to a fifth aspect, there is provided a method of cleaning a dispenser head according to the invention, comprising: The method further comprises: connecting the dosing mechanism to the cleaning fluid at a pressure sufficient to cause the cleaning fluid to enter the dispenser head; and then removing the dosing mechanism from fluid communication with the cleaning fluid source. and removing the cleaning fluid from the dispenser head.
[0013] Various dispenser head and in-line dispenser head configurations and liquid products The dispensing method and cleaning dispenser system are contemplated by the present disclosure, including but not limited to: Some illustrative and non-exhaustive examples are described below.
[0014] The dispenser head of the present invention may be provided in an assembled form as in use, It may be provided in kit form or in a partially assembled form. In an embodiment, the pump, dilution mechanism, dosing mechanism, and outlet nozzle of the dispenser head comprise: Preferably, the unitary structure is formed by any suitable method, for example, injection molding. It includes a single plastic device made by molding.
[0015] Suitably, the source of concentrate may comprise a container for containing the concentrate, the container comprising: A mounting mechanism is provided to allow concentrate to flow from the container into the pump in response to operation of the pump mechanism. Can be connected to a pump.
[0016] The dispenser head is releasable to remove the container from the dispenser head. It may be attachable to a container of concentrate by an operable coupling mechanism. The dispenser head is fixedly attached to a container of concentrate, and dispenses the contents of the concentrate in the container. Once empty, the dispenser system can be disposed of.
[0017] In some exemplary arrangements, the pump pumps the concentrate as a series of discrete amounts or The concentrate may be delivered as a continuous flow. may be predetermined or may be controllable by an adjusting means.
[0018] In some exemplary arrangements, the dilution mechanism facilitates rapid dilution of the concentrate with the diluent, As a result, the viscosity and / or Brix value of the concentrate blended into the foaming additive liquid by the addition mechanism while reducing or substantially eliminating premature or excessive foaming of foaming additives. It may be configured to avoid this.
[0019] In use, the dilution chamber receives the concentrate delivered by the pump and the diluent duct delivers the dilution The dilution mechanism can deliver the diluent from the agent source to the dilution chamber. The dilution mechanism converts the concentrate into the diluent in the dilution chamber. The concentrate may be configured to be mixed with the water to produce a diluted concentrate. No diluent needs to be added; in this case, the undiluted concentrate flows from the pump through the dilution mechanism. The diluted or undiluted concentrate is then pumped from the dilution chamber to the dosing mechanism. The dispenser head (more specifically, the dilution mechanism or the addition mechanism) , including a flow regulator means for permitting the flow of liquid from the dilution chamber to the additive chamber. Preferably, the flow regulator means is one-way, thereby allowing flow from the dilution chamber to the additive chamber. The additive chamber allows liquid flow to the dilution chamber, but prevents liquid flow from the additive chamber to the dilution chamber.
[0020] The diluent can enter the diluent chamber through the diluent orifice, and the diluent orifice The outlet area is large enough to produce a jet of diluent to promote mixing with the concentrate. In other words, the cross-sectional area of the diluent orifice is small relative to the rate at which the diluent is introduced into the dilution chamber. is substantially greater than the average velocity through the rest of the diluent duct. The cross-sectional area of the dilute liquid may be significantly smaller than the average cross-sectional area of the rest of the liquid duct. Injecting the dilution chamber at a constant rate, and therefore the concentrate in the dilution chamber, allows for a comparison of the dilution and concentrate. This may have the aspect of promoting relatively rapid mixing.
[0021] If the area of the diluent orifice and the diluent pressure are known (e.g., if the diluent pressure is (if controlled by a pressure regulator), allowing diluent to flow into the dilution chamber. By controlling the duration of the dilution, the amount of diluent introduced into the dilution chamber can be determined and controlled. For example, the shutoff valve of the diluent can be controlled to open or close the shutoff valve. This allows or blocks the flow of diluent.
[0022] In some instances, the diluent may be water supplied from a primary water source.
[0023] In a preferred embodiment, the diluent orifice is upstream of the pump outlet.
[0024] It may be desirable to prevent concentrate from entering the main water supply or other sources of diluent. Concentrates (whether diluted or not) are used in conjunction with the supply of additive fluids such as carbonated water or nitrogen liquid. It may be desirable to prevent the concentrate from entering the supply (in some cases, the concentrate may be High sugar, Brix, and / or fat content, which can promote biological growth In certain circumstances, there may be legal requirements not to contaminate the main water supply or additional fluid supplies. There may be hygiene reasons for not contaminating the supply. Contamination or timing of concentrates that may make it difficult or impossible to achieve the desired dilution ratio later Water or carbonated water from the main water source enters the concentrate source container to avoid premature partial dilution. In consideration of these points, it is recommended to at least clean the dilution chamber and The concentrate, diluted concentrate, or any liquids subsequently mixed together return through the diluent orifice. To ensure this does not occur, the concentrate flow must be stopped before the diluent supply is stopped. The diluted concentrate and / or additive fluid may need to be combined and mixed before being added to the additive stream. The fluid flows downstream (downward) from the outlet of the body without coming into contact with the outlet of the additive fluid, and then flows The body must be able to prevent the mixed liquid product from re-entering the duct that supplies the additive fluid. , may pass through a washer-type check valve. The concentrate may be diluted or undiluted depending on whether the additive fluid is diluted or undiluted. Do not force concentrate up into the dilution chamber or through the diluent orifice. , introduced into a zone of the additive chamber at a pressure lower than the supply pressure of the diluted or undiluted concentrate. That's fine.
[0025] In some exemplary arrangements where water is introduced to the dispense head from a main water source, the water from the main water source It may be desirable to maintain the pressure within a controlled normal range. The dispenser head is suitable for receiving water at a pressure of approximately 150 kPa (1.5 bar). Many areas provide mains water at at least this pressure, so increasing the pressure Rather than introducing a water pump into the system to reduce the pressure (i.e., For example, if the pressure of the dilution water is about 150 kPa, If it is known that the velocity of water passing through a diluent orifice of known area is can be determined.
[0026] If the flow rate of the diluent is substantially constant, the period during which the dilution water is allowed to flow into the dilution chamber can be controlled. This allows for the amount of diluent mixed with the concentrate (in other words, the ratio of diluent to concentrate). ) can be determined and adjusted. For example, if the dilution water (or other liquid) is about 20 ml, / s (milliliters per second) through a restrictive orifice, and if the desired dilution ratio is 2:1, The pump mechanism must deliver concentrate at a rate of approximately 6.6 ml / s (i.e., 20 ml / s divided by 3). For example, if you pour a 200ml drink into a glass, the total flow rate will be approximately 26.6ml / s. When dispensing 200 ml, the required time is approximately 7.5 seconds (i.e., 200 ml ÷ 26.6 ml / s). In another example, the concentrate must be diluted at a ratio of 4:1 (diluent to concentrate). In one case, the pump mechanism delivers approximately 4.0 ml / s (i.e., 20 ml divided by 5) of concentrate. The total flow rate is about 24 ml / s, which is the time it takes to fill a 200 ml glass. The time between the injection and the time required is 8.33 seconds (i.e., 200 ml ÷ 24 ml / s). One might think that the dispensing time for the model is convenient and short enough, but the higher the concentration of the solution, the In an example where a 24:1 dilution ratio is required, the pump mechanism pumps approximately 0.8 ml / s (i.e., 20 ml / s ÷ 25) flow rate, which takes approximately 9.6 seconds. This dispensing time can be considered relatively long to dispense a glass of beverage. An example of a method to reduce dispensing time when a relatively high dilution ratio is required is to By using a dispenser system with a large area of restrictive orifice that allows the Deaf.
[0027] The dispenser head according to the present invention may be configured to have a diluent orifice size and / or a dispenser orifice size. RFID means, or other suitable data storage and and display means, such data display means being connected to the control system and / or pump. An exemplary data display means may be in communication with the dispenser head drive mechanism. It may also be possible to communicate other operating parameters for operating the display. Modify parameters for supplying concentrate, diluent, and / or additive fluid to the pen head It may be possible to do this.
[0028] The pump prevents the concentrate from passing from the pump outlet to the pump inlet, and the concentrate is pumped a seal member operable to be pressed against the rotor and to discharge the seal member to the outlet; The sealing member may be a diaphragm seal or a seal formed in the pump housing. The pump and the diluent duct may be a membrane that is a sufficiently thin and elastic part of the diluent duct. The pressure of the diluent in the valve is transmitted to the rotor through the seal member. For example, the diluent duct may be configured so that the diluent flows behind the sealing member (i.e., behind the rollers in use). The side of the seal member opposite to the side that contacts the rotor is configured so that the air can flow The pressure of the diluent may be such that the concentrate flows between the rotor and the surface of the pump housing. Pressing the seal member against the rotating rotor with sufficient force to prevent passage For example, if the diluent is tap water, the diaphragm seal A pressure of 150 kPa is required on the diaphragm seal to press it against the rotor. Furthermore, the pressure drop across the diluent orifice can be adjusted to reduce the pressure of the diluent after passing through the diluent orifice. This means that the pressure in the diluent orifice is lower than the pressure in front of the diaphragm. is constantly pressed against the rotor to form a seal, preventing the diluent from passing through the pump. to prevent it from passing through to the source reservoir.
[0029] In some instances, the dilution mechanism disperses the concentrate and promotes mixing with the diluent. A concentrate distributor means may be included to increase the surface area of the concentrate. The concentrate disperser means disperses the concentrate as a film to facilitate mixing with the diluent. For example, the disperser means may be configured and arranged to disperse the dispersed liquid in a radial direction. The liquid flow is deflected so that the flow is in a substantially uniform azimuth direction about the central axis. By adding An annular or circular disc (washer) constructed and arranged to distribute the In some instances, the concentrate dispersion may include a resilient member shaped as a resilient member such as a resilient foam. The container means may include atomizer means for forming the concentrated liquid into a plurality of droplets.
[0030] In some exemplary arrangements, the dilution mechanism (more specifically, the concentrate disperser means) disperses the diluent a stray tube configured to transport the concentrate over an expanded channel operable to promote mixing with the In other words, the dilution mechanism may include a passageway through which the concentrate and the diluent can mix. A complex or reticulated system through which concentrates and dilutes can flow is used to extend the pathways and time A flow path arrangement may be configured.
[0031] Preferably, the diluted or undiluted concentrate is combined with the additive fluid in the additive chamber. Diluted or undiluted concentrates can be dispensed at the reception desk where the liquid is to be dispensed. Preferably, all aspects of the invention are at least partially compounded within the container. In this case, at least a part of the diluted or undiluted concentrated liquid and the additive liquid are simultaneously fed to the adding mechanism. and / or at least partially compounded within the dosing mechanism. The mixture is mixed partially in the dosing mechanism and partially in the receptacle. Alternatively, the compounding may occur only within the receptacle.
[0032] In some exemplary arrangements, the additive inlet may be a foaming liquid, e.g., an additive fluid inlet. The body may be configured to be substantially free of nucleation sites for forming bubbles. The additive duct shall be substantially free of abrupt changes in direction or cross-sectional area and / or have no corners or surface irregularities. It may be possible to avoid this.
[0033] In some exemplary arrangements, the additive chamber may include a bubble nucleation means, and / or Alternatively, it may be configured to include nucleation sites to promote the formation of bubbles. For example, the additive chamber may be fitted with gauze, openwork, or other suitable material to facilitate abrupt changes in direction and / or cross-sectional area. Such an arrangement may include a mesh or textured surface. This may be suitable when the liquid is a nitrogenated liquid, in which part of the nitrogen gas It is not absorbed (i.e., dissolved) in water or other carrier liquids and forms microbubbles (i.e. The carbon dioxide remains in the form of bubbles (i.e., bubbles with a relatively small average size). Unlike carbonated water, which is present in the water, it can be relatively difficult to get the bubbles out of solution. Although it is possible that a head of foam may form in the dispensed liquid, it is desirable to If not, the agitation of the beverage in the beverage receptacle may be insufficient to achieve the desired amount of foam. This may require a surface that is structured to promote bubble nucleation. .
[0034] In some exemplary arrangements, the dosing mechanism includes an additive fluid dispersing mechanism for dispersing the additive fluid within the additive chamber. It may contain an additive disperser means, and before being incorporated into the diluted (or undiluted) concentrate, The additive fluid may be dispersed in the
[0035] The beverage dispenser according to the present invention includes a diluent flow rate regulator that regulates the flow rate of diluent to the dilution mechanism. The control system may further comprise a control means and / or the control system may further comprise an addition mechanism. The diluent and / or additive may be provided with an additive flow regulator means for regulating the flow rate of the additive to the diluent and / or additive. The flow regulator means for the additive fluid is configured to regulate the flow rate of the diluent fluid received from the diluent source / additive fluid source, respectively. operative to counteract changes in the flow rate of the diluent in response to changes in the pressure of the dilution / addition fluid. The pressure-responsive flow control means may be included (the flow rate of the fluid is the amount of fluid passing through a unit area per unit time). (It may be adjusted in terms of flow rate, or flux, which is the mass of fluid passing through.) The additive flow regulator means regulates the additive flow rate when the additive source pressure is 1000 kPa. The additive flow rate is 110% or less of the additive flow rate when the additive source pressure is 600 kPa. In another example, the additive flow regulator means may be configured such that the pressure is 600 kPa. The flow rate of the additive fluid when the pressure of the additive source is 100 kPa is 110 times the flow rate of the additive fluid when the pressure of the additive source is 100 kPa. % or less.
[0036] An exemplary flow regulator means is a resilient valve having a central orifice connecting opposing ends. The orifice is constructed of a flexible member, and the flowing fluid flows through the orifice, which reduces the cross-sectional area. The increase in fluid pressure is accommodated by increasing the cross-sectional area, and the decrease in fluid pressure is accommodated by increasing the cross-sectional area. The present invention may be configured as follows.

The processor means may be configured to operate by determining whether sufficient volume of diluent is present in the dilution chamber. The diluent flow control means is opened for a certain period of time, and then the diluent flow control means is closed. It may be configured as follows.

The diluent flow control mechanism is operated for a period of time sufficient to allow the determined volume of diluent to enter the dilution chamber. and then operable to close the diluent flow control mechanism. The sugar content data may be expressed as a Brix value such as degrees Brix.
[0043] In one embodiment, the dispenser head of the present invention comprises a plurality of components operably connectable to one another. The system may include a first element including a dilution mechanism, and a second element including an addition mechanism. For example, the dispenser head may include a coupling for reversibly connecting the dosing mechanism to the dilution mechanism.

The auxiliary fluid supply system may be configured as follows: The auxiliary fluid supply system may be configured to supply a carbonation or The apparatus may be configured to supply a nitrogenated aqueous additive fluid. Maintaining the temperature between 2°C and 10°C is partly to maintain the pot life of the concentrate. In some cases, it is desirable to control the temperature of a mixed liquid (e.g., a beverage) dispensed into a receptacle. For example, the concentrate may be kept at about 6°C. If the temperature of the concentrate is too low, If the temperature of the concentrate is too high, the viscosity will become too high and it will be difficult to flow. If the temperature of the concentrate is too high, the storage period will be shortened. There is a possibility that it will become

DETAILED DESCRIPTION OF THE INVENTION
[0052] As used herein, a foamable liquid is a liquid that can be foamed by, for example, reducing pressure or temperature across a carrier liquid. A foamable liquid is a liquid that can foam in response to an increase in pressure. The molecular species may be in a gaseous state and may come out of solution in the form of bubbles. For example, sparkling water (or other liquids such as dairy liquids) can be mixed with water (or other liquids). may consist of carbon dioxide or nitrogen or nitrous oxide dissolved and / or suspended in .
[0053] Carbonated drinks contain carbon dioxide dissolved in the beverage, and bubbles of carbon dioxide escape from the solution during effervescence. Nitrogenated drinks have nitrogen suspended in the drink, and nitrogen bubbles are generated when the drink fizzes. Nitrogen is less soluble in water than carbon dioxide, but relatively tiny nitrogen bubbles are suspended in the water. Nitrogenated liquids consist of nitrous oxide, nitrogen, or air bubbles suspended in the liquid. For example, nitrogen may be introduced into beer or coffee, and the nitrogenated beer may be put into a keg. Unless otherwise specified, the term "carbonated" is used herein to mean "carbonated" or "carbonated" " or "nitrated," meaning that the carbonated liquid contains dissolved carbon dioxide or dissolved and / or The carbonated liquid may contain suspended nitrogen. The carbonated liquid may be effervescent, and the effervescent properties may be determined by the This involves the generation of carbon dioxide or nitrogen bubbles.
[0054] The additive fluid may be a carbonated liquid, preferably carbonated water, a nitrogenated liquid, preferably nitrogenated water, or a dairy liquid. containing or consisting essentially of water or other aqueous liquids, It may contain dissolved or suspended carbon dioxide or nitrogen. Levels generally increase with increasing pressure and decreasing temperature, e.g., maximum concentrations in water This can be achieved by cooling water to near freezing point. This can easily cause bubbles to form in liquids such as water, which is known as foaming. The rate at which gases such as carbon dioxide and nitrogen dissolve from a liquid depends on the amount of gas bubbles introduced into the liquid. The number and size distribution of the particles, the pressure applied to the liquid, and the time it takes to reach the saturation level do.
[0055] Referring to FIG. 1, an exemplary in-line beverage dispenser assembly for dispensing beverage B is shown. The assembly 100 includes an exemplary dispenser head 200 and an exemplary auxiliary fluid system 40. The dispenser head 200 may include a pump 220, the input The port is for beverage B so that pump 220 can pump concentrate C from container 300. The auxiliary fluid system 400 is connected to the outlet of the container 300 containing the dilution concentrate C. A diluent liquid D is supplied via the additive channel 420 to dilute the concentrate C, and the additive channel An additive fluid A can be supplied via channel 430. In some examples, the auxiliary fluid The system 400 provides a foamable additive fluid A via an additive channel 430. The pump 220 pumps a series of volumes of concentrate C from the container 300 to the dilution chamber (shown in FIG. 1). The diluent duct (not shown in FIG. 1) can be connected to the diluent channel. The diluent D can be transported from the pipe 420 to the dilution chamber, in which the concentrate C is mixed with the diluent D. Concentrate C can be diluted by mixing, thereby reducing its viscosity. condensate C d can flow from the dilution chamber to the additive chamber (not shown in FIG. 1). If the viscosity or dilution rate of the solution is low enough, dilution with diluent D may not be necessary. In this example, the delivered concentrated solution C passes through a dilution mechanism including a dilution chamber and is mixed with the diluted solution. The concentrated solution C can flow into the additive chamber included in the adding mechanism without being diluted. Regardless of whether it is diluted with liquid D or not, the liquid passing from the dilution mechanism to the addition mechanism is Unless otherwise specified, the term "Diluted Concentrate C" is used herein. d The addition mechanism is called Received and diluted concentrate C d and discharged through outlet nozzle 262 into a receptacle (FIG. The apparatus may be configured to provide beverage B dispensed into a container (not shown).
[0056] Beverage B generally contains a predetermined or calculable amount of concentrate C, diluent D, and additive fluid A. The dispenser assembly shown in FIG. 1 may include at least one pump. Operating parameters (e.g. whether the pump is activated or deactivated), flow into the dilution mechanism and an adjusting mechanism operable to adjust the amount of diluent D flowing into the dosing mechanism and the amount of dosing fluid flowing into the dosing mechanism. For example, the adjustment system may include a control system (not shown) for adjusting the diluent D to the diluent channel. A diluent valve mechanism (not shown) for regulating whether or not diluent can flow from the nozzle 420 to the dilution mechanism. and to adjust whether or not the additive fluid A can flow from the additive fluid channel 430 into the additive mechanism. and an additive liquid valve mechanism (not shown).
[0057] The regulation system is based on input data received and processed by an electronic processor. a computer microprocessor configured to control the operation of the removal valve mechanism and the addition valve mechanism; The fluid supply system may also include an electronic processor (not shown), such as a processor. The stem 400 is a radio frequency transducer that can indicate the flow rates of the diluent D and the additive fluid A, respectively. The control system may include a radio frequency identification (RFID) device. and receiving the data transmitted by the electronic processor and transmitting the data to the electronic processor for processing. In some instances, the device may include an electronic processor. The actuator allows the dilution fluid D and the additive fluid A to flow into the dilution mechanism and the additive mechanism, respectively. In order to do this, the respective periods during which the diluent valve mechanism and the additive valve mechanism should be in an open state are set as follows: The electronic processor device may be configured to determine the flow rate of each of the After each period, the diluent valve and the addition valve are activated by issuing an electronic control signal. In this way, the diluent to be mixed with the concentrate C can be The amount of fluid D and added fluid A may be determined and adjusted. To input the information, a means other than an RFID device, such as a QR code or Barcode readers are also envisioned.
[0058] The effervescent additive liquid may be saturated with carbon dioxide or nitrogen to a known value, thereby The amount of additive fluid to be introduced can be calculated. For example, the foaming additive liquid is preferably: It is provided at about 2°C, a temperature at which the saturation level may be known.
[0059] In the example where additive fluid A is a sparkling liquid such as carbonated water, nitrogenated water or other aqueous liquid, It may be desirable for the composition to exhibit some degree of foaming. The degree of foaming is determined by the amount of bubble formation. It may be characterized as potentially releasing dissolved carbon dioxide or nitrogen from the solution in the form of bubbles. It is expressed by the amount of gas generated from the beverage B when it is released. The bubble formation rate may be characterized in terms of the number and size distribution of bubbles, and / or the rate of bubble formation. The foaming should be within a certain range; if it is too foamy, Beverage B will have excessive foam. Too little fizz can cause beverage B to become too flat (i.e., the beverage In some cases, the dispenser head may , may have the aspect of achieving a desired amount of foam in beverage B.
[0060] 2A-2E, an exemplary dispenser head 200 is shown. The device includes a mounting mechanism 210 for attaching the head 200 to a container 300 containing the concentrate C. The exemplary attachment mechanism 210 may be configured to transfer the concentrate C from the container 300 to the input of the pump 220. The container 300 includes a duct 211 for transporting the liquid to the outlet 221A. It may be provided as a removable or integral unit as part of the head 200, The attachment mechanism 210 may be provided separately from the dispenser head 200. 00.
[0061] With particular reference to FIG. 2C, the exemplary pump 220 includes a roller mounted within a pump housing 223. The rotor 225 may include a rotor 225 coupled to the rotor transmission mechanism 222. The rotor 225 may be driven by a motor (not shown) connected to the rotor 225 (in FIG. 2C, the axis of rotation of the rotor 225 is (perpendicular to the page). Pump housing 223 houses rotor 225. The rotor 225 can rotate so that its surface area contacts the inner surface of the pump housing 223. The pump housing 223 may have a cylindrical inner surface that can be slidably mounted. The pump housing 223 may comprise a resilient material. The rotor 225 slightly presses down on the inner surface of the pump housing 223, and the pump housing 223, and the pumped concentrate C , the portion between the rotor surface area and the inner surface of the pump housing 223 where they abut against each other. In the particular example shown, the surface of the rotor 225 may be radially The rotor 225 has a pair of poles spaced apart from each other on the radially opposite sides thereof. The pump chamber 226 includes two opposing surface areas (FIG. 2C shows one of the pump chambers). (Only one pump chamber 226 is shown). The volume of each pump chamber 226 is This defines the volume of each amount of concentrate C sent to the dilution chamber 232. 226, when each pump chamber 226 is in fluid communication with pump inlet 221A, The rotor 225 is driven to rotate during use. (clockwise as shown in FIG. 2C), concentrate C in pump chamber 226 is pumped by the pump Chamber 226 is now in fluid communication with pump outlet 221B, and concentrate C flows from pump chamber 226 to The fluid is transported around the pump housing 223 from the pump outlet 221A until it is discharged through the pump outlet 221B.
[0062] In the particular example shown in FIG. 2C, pump 220 includes a sealing membrane 227. The membrane may be formed as an integral part of the pump housing 223 or may be welded, bonded, or otherwise attached. The seal membrane 227 may be bonded to the rotor housing 223 by adhesive or other means. The rotor surface has a relatively complex shape, including a radially recessed area that forms the cavity 226. The resilient compression member 213 is sufficiently resilient to keep the sealing membrane 22 in a closed position. 7, i.e., the compression member 213 may be disposed in the rear chamber 212 behind the rotor 225. It may be arranged on the side of the sealing membrane 227 opposite to the contact side. The compression member 213 is elongated and generally "U" shaped when viewed in cross section, as shown in FIG. 2C. The rear chamber 212 has a pair of narrow grooves 216 which are seated against a fixed backing wall 214 of the rear chamber 212. The ribs protruding from the opposite side of the resilient compression member 213 are attached to the sealing membrane 22. 7, that is, the side surface of the sealing membrane 227 facing the rear chamber 212. The elastic compression member 213 is configured to compress the backing wall 214 and the sealing membrane 215. 27, so that the rotor 225 is compressed between the rotor housing When driven to rotate within the housing 223, the ribs of the resilient member 213 act as a seal membrane. The sealing membrane 227 can be pressed against the surface of the rotor 225. The condensate C passes between the seal membrane 227 and the rotor 225, resulting in the pump outlet 221B from the pump chamber 226 to the pump outlet 22 1B. This becomes the case.
[0063] The exemplary pump 220 described with reference to FIG. 2C pumps concentrate C into a series of wells, each of known volume. The diluter rotates at a known speed determined by the angular velocity of the rotor 225 and the total number of degrees of rotation. The concentrate C can be dispensed from the container 300 as a series of amounts delivered to the system. The capacity is defined by the volume of each pump chamber 226. The amount of concentrate C dispensed may be determined as a number of amounts. Different types of pumps may be used, and these pumps may have known or selectable flow rates. The concentrate C may be delivered as a continuous stream.
[0064] In various exemplary arrangements, the pump 220 may be substantially similar to that of International Patent Application Publication No. WO 2004 / 020994. 6 / 027548, International Patent Application Publication No. 2010 / 122299, International Patent Application Publication 2013 / 050491, International Patent Application Publication No. 2014060418, International Patent Publication No. International Patent Application Publication No. 2013 / 050488, International Patent Application Publication No. 2013 / 117486, or any of those disclosed in International Patent Application Publication No. WO 2014 / 135563; or The compounds disclosed in British Patent Application Publication No. 2551663 or British Patent Application Publication No. 2507029 Substantially any pump mechanism disclosed in these publications may be used (although exemplary pump mechanisms may be (The present disclosure is in no way limited to that disclosed in the publication).
[0065] In certain instances, especially when additive fluid A is a foaming liquid, concentrate C may be mixed with a suitable diluent D. It is desirable to reduce the viscosity of concentrate C before combining with additive fluid A by diluting it with This may result in the foaming additive fluid A being diluted with concentrate C. d Gentle enough to Can be formulated to reduce premature or excessive foaming of added fluid A or dispensed beverage B , minimized, or prevented.
[0066] The illustrated exemplary dilution mechanism includes a dilution housing 230 containing a dilution chamber 232 and a make-up fluid a diluent channel 420 for transporting diluent D from the diluent channel 420 of the system 400 to the diluent chamber 232; The dilution chamber 232 is in fluid communication with the pump outlet and is provided with a dilution duct. The diluent duct can receive and mix not only the dilution liquid C but also the diluent D. and a diluent chamber 232. The diluent chamber 232 is operable to transport the diluent D from the fluid channel 232. For example, the diluent duct may include a diluent chamber 23. 2 may be formed with a diluent inlet 234 and an orifice 235.
[0067] In the particular example shown in Figures 2C and 2D, the diluent duct may include a rear chamber 212. The pressure of the diluent D is therefore The force is transmitted to the rear side of the seal membrane 227, pressing the seal membrane 227 against the surface area of the rotor 225. to supplement or replace the force applied to the sealing membrane 227 by the resilient compression member 213. In some other examples, the diluent duct is sealed to the rear chamber 212 by a barrier means. The force applied to the sealing membrane 227 may be separated from the compression member 227. 13 and the restrictive orifice 235 (especially if its area is sufficiently small, If the liquid passing through it appears as a jet of liquid, it is called a "jet orifice." The pressure difference may be in combination with a differential pressure across a
[0068] With particular reference to Figures 2C and 2D, the diluent duct is configured such that the diluent liquid D passing therethrough is having a sufficiently small area to spray a jet of diluent liquid D into the dilution chamber 232 The jet orifice 235 may also be included to promote turbulence and increase the flow rate of the pumped concentrate C This may have the aspect of promoting rapid mixing of the jet of diluent liquid D with the jet of diluent liquid D. The area of the orifice 235 is substantially smaller than the average cross-sectional area of the remainder of the diluent duct. 232, so that the diluent liquid D passes through the jet orifice 235 into the dilution chamber 232. There is a substantial increase in velocity and a drop in pressure as the mixture is released.
[0069] 2C and 2D, an exemplary dispenser system may dispense a diluted concentrate. C d promotes turbulence in the diluent D and concentrate C, thereby promoting rapid and thorough mixing of the diluent D and concentrate C. a diluted concentrate C constructed and arranged to d a one-way valve 250 through which the The one-way valve 250 may regulate the flow of the diluted concentrate as it passes from the dilution chamber 232 to the dosing mechanism. C dPreferably, the additive fluid A is arranged on the path of the dilution chamber 232. The dilution mechanism or the addition mechanism is a one-way valve. 250, and a one-way valve may be disposed between the dilution mechanism and the addition mechanism.
[0070] Referring to FIG. 2E, an exemplary one-way valve may include an annular device, such as a polymer washer. The resilient member 250 is in the form of a disk or ring. The resilient member 250 may extend generally radially from the dilution mechanism 200. When the fluid is not passing from the dilution mechanism to the addition mechanism, it is abutting against the seat area of the housing of the dilution mechanism. At least partially diluted concentrate C d is contained within the dilution chamber 232, and the resilient member 25 0 side and diluted concentrate C d If the pressure is large enough, the elastic member 2 The peripheral area of 50 may be biased away from the seat, thus d to pass between the peripheral region and the seat and into a chamber 268 contained in the dosing mechanism. In this way, diluted concentrate C d The velocity of the , so that the at least partially diluted concentrate C d The increased turbulence in the diluted Concentrate C d Before being mixed with additive fluid A, the mixture of diluent and concentrates D and C is homogeneous. Furthermore, diluted or undiluted concentrate C d Radial direction of The outward moving flow impinges on the radial walls of the additive chamber, releasing diluted or undiluted Concentrate C dThis can cause turbulence in the air, thereby further promoting mixing.
[0071] In some examples, the diluent is pumped through the diluent orifice 235 at a pressure of about 150 kPa. The diluent D may be introduced into the dilution chamber 232. This may cause some mixing of the diluent D and the concentrate C. This is likely to occur, but the diluted concentrate mixture may not be homogeneous. The diluted concentrate is then pumped through a resilient valve, which in some instances may include an elastomeric washer valve. The diluted concentrate C is passed through a resilient member 250 which is flexible and allows the diluted concentrate C to pass through the resilient member 250. d The degree to which the resilient washer 250 flexes allows the liquid to pass from the dilution chamber 232. Generally, diluted concentrate C d The viscosity and pressure of the washer 250 will determine the amount of water that can be used. In certain preferred exemplary arrangements, the diluted concentrate C d is pressed into a relatively thin film. A sufficient amount of diluted concentrate C d In order to pass through this thin filter The length of the film must be large enough relative to the thickness of the film, which is achieved by using a resilient washer. This can be achieved if the valve 150 is circular and has a sufficiently long circumference. Diluted Concentrate C d may move at high velocities and, as a result, at relatively low pressures. The film exits into the first volume 268 of the additive chamber, which contains the diluted concentrate C d The diluted concentrated film is directed toward the central region of the first volume 268. Condensate C d The high velocity of the particles and the sudden change in their direction of movement cause further mixing and homogenization. It is likely that upon exiting the first volume 268 of the additive chamber, the diluted concentrate will be substantially uniform. It may also be a dilute mixture.
[0072] With particular reference to FIG. 2D, the adjustment system of the dispenser system 200 includes a diluent inlet a diluent flow control mechanism 275 for regulating the flow of diluent liquid D through the passage 234; For example, the diluent flow control mechanism 275 may be in an open state to allow the diluent D to pass through. or the diluent shutoff valve 275 is in a closed state to prevent the diluent D from flowing into the diluent duct. The diluent shutoff valve 275 may include a shutoff valve that can be connected to the diluent inlet 234. The diluent shutoff valve 275 may be seated within an attachable valve housing 270. The actuator may be electrically actuable by a solenoid device (not shown), which , may be controlled by an electronic processor unit (not shown). When the concentrated liquid C is sent to the dilution chamber 232 using the valve 275, the dilution liquid shutoff valve 275 is opened. This allows the diluent D to flow into the dilution chamber 232 and mix with the concentrate C. Once the volume of diluent D has entered the diluent chamber 232, the diluent shutoff valve 275 may be automatically closed. The required amount of diluent D is calculated by the flow rate of the diluent (e.g., the amount of diluent flowing through a unit area per unit time). D) multiplied by the period during which the diluent shutoff valve 275 is open. It may be determined as:
[0073] The additive mechanism reduces or substantially reduces premature or excessive foaming of the effervescent additive fluid A, such as carbonated water. the first and second additive chambers being substantially free of corners or sharp turns to effectively prevent The additive housing 260 may include volumes 268, 266 and an additive inlet 264. Diluted concentrate C d(or in some instances, undiluted concentrate) in some example configurations , from the dilution chamber 232 through the one-way valve 250 into the top volume 268 of the additive chamber. In addition, additive fluid A can be introduced from additive channel 430 of auxiliary fluid system 400. , via additive inlet 264, into the additive chamber volume 266, where the diluted Diluted Concentrate C d and dispensed through an outlet nozzle 262 into a cup or The additive fluid A and the diluted or Undiluted Concentrate C d is partially or substantially entirely within the additive chamber and / or receptacle. The addition mechanism promotes gas nucleation, resulting in the addition of the additive fluid A or It may contain a sieve (not shown) or other suitable agitation means to promote foaming of beverage B. It is also common for nitrogen-filled liquids to foam (i.e., for bubbles to nucleate). It can be used for certain liquids that need to be stirred. For example, stirring sieves can be used for: A sieve or similar hole having a diameter of approximately 750 microns is located at or near the outlet nozzle 262. It may include a faceted hole in the cross section.
[0074] With particular reference to FIG. 2D, the regulating mechanism adjusts the flow of additive fluid A through additive inlet 264. For example, an additive flow control mechanism 285 may be included to control the amount of additive flow. The mechanism 285 is in an open state where additive fluid A can pass through, or in a state where additive fluid A is in the volume 266 of the additive chamber. The additive shutoff valve 285 may be configured to close to prevent the additive from entering the additive shutoff valve. The additive shutoff valve 285 may be a valve house mountable adjacent to the additive inlet 264. The additive shutoff valve 285 may be seated adjacent to the housing 280. It can be electrically actuated by a solenoid device (not shown) controlled by a When the dispenser head 200 is in use, the additive shutoff valve 285 is kept open. This may allow additive fluid A to enter the additive chamber volume 266. After additive fluid A enters additive chamber 266, additive shutoff valve 285 automatically closes. The required amount of added fluid A is determined by the flow rate of the added fluid (for example, the flow rate per unit area per unit time). (for the mass of additive fluid D being added) multiplied by the period during which the additive shutoff valve 285 was open may be determined as being proportional to
[0075] The regulation system may include a pressure responsive valve 282 disposed within a valve housing 280 For example, the pressure responsive valve 282 may include a passage through which carbonated water A can flow, approximately The speed at which carbonated water at a temperature of 1℃ to about 10℃ passes through the passage is about 140kPa to about 1000kPa. substantially constant over a pressure range of 100 Pa (e.g., from about 16 ml / s to about 24 ml / s, or about 20 ml / s) (in some arrangements, up to about 10 Higher saturation can be achieved by using a higher pressure of 00 kPa. Generally, the pressure responsive valve 282 operates in a range of about 100 kPa to about 1000 kPa. The variation in the flow rate of the cooled effervescent additive fluid A as a function of the pressure of additive fluid A is shown in Figure 1. The foaming additive fluid A may be limited to about 10% or less, plus or minus about 5%. contains dissolved carbon dioxide or suspended nitrogen below its saturation solubility under prevailing conditions. In this way, the amount of added fluid A is controlled by the timing of the operation of the shutoff valve. obtain.
[0076] In the example where additive fluid A is a foaming liquid, the content of dissolved carbon dioxide or suspended nitrogen is preferably at or near the saturated solubility level, and the saturated solubility level is substantially This is because the temperature is low (e.g., below the freezing point of the liquid). This can be achieved by providing the foaming additive fluid A at a temperature (slightly above 100°C) and at a relatively high pressure. The average diameter (or diameter of the supply pipe (not shown) that conveys additive fluid A to pressure responsive valve 282) is The cross-sectional area (or cross-sectional area) is generally less than the average diameter (or cross-sectional area) of the passageway through the pressure responsive valve 282. This is because the pressure of the additive fluid A upstream of the pressure responsive valve 282 may be substantially greater than the The liquid is kept saturated with the foaming gas while reducing or substantially preventing foaming at this stage. The additive inlet 264 is designed to prevent excess gas from leaking out. To reduce the amount of pressure drop across the pressure responsive valve 282 that may cause In some exemplary arrangements, the flow rate and amount of diluent D is It may be controlled by a mechanism similar to that disclosed for entity A.
[0077] 3A-3C, an exemplary dispenser head 200 includes a pump 220 and , for connecting the inlet of the pump 220 in fluid communication with a container containing a beverage concentrate C. The system may include a connection adapter 210, a dilution mechanism, an addition mechanism, and an adjustment system. An exemplary dilution mechanism includes a dilution chamber 232 within a dilution housing 230, and a diluent D in the dilution chamber 232. a diluent duct including a diluent inlet 234 and an orifice 235 that can pass through the diluent duct; The dosing mechanism may include an additive housing 260 and a diluent valve 250. Inlet 244, first additive volume 268, second additive volume 267, third additive volume 268, 66, an additive chamber including a fourth additive volume 269 and an outlet nozzle 2 for dispensing beverage B. 62. The additive housing 260 may be connected to the dilution housing 62 by a connection mechanism 238. It can be releasably coupled to the housing 230 .
[0078] Figures 3B and 3C show the addition mechanism for a particular example in more detail. d (which may consist of diluted or undiluted concentrate C) from the dilution chamber 232 , through one-way valve 250 into first volume 268, and then through second volume 266. The second volume 266 can pass through the first volume 269 of the additive chamber. a generally cylindrical volume extending longitudinally between a first volume 268 and a fourth volume 269; The third volume 269 of the additive chamber is located adjacent to the outlet nozzle 262. The second chamber 266 is surrounded by the second chamber 266 and extends coaxially therewith. The diluted concentrate C is transported to a generally annular third volume 267 via the agent inlet 244. d Import The second and third volumes 266 may be distributed azimuthally around the second volume 266. The chambers 266, 267 are separated by a generally annular wall. The additive fluid A in the volume 267 can pass to the fourth volume 269, but the fluid cannot pass through the fourth volume 269. The third volume 267 and the fourth volume 269 are separated so that the air cannot pass through from the third volume 267 to the fourth volume 269. The one-way addition valve may include a resilient washer valve 270, and the dilution Concentrate C dIt may operate in the same manner as the upstream one-way valve 250 through which the That is, the pressure of the additive fluid A in the third volume 267 causes the peripheral portion of the resilient washer valve 270 to seat. The flow is directed away from the valve seat and passes between the resilient washer valve 270 and the seat. The solution A is diluted and concentrated in the fourth volume 269 before being dispensed through the outlet nozzle 262. Object C d It can be combined with.
[0079] The foaming additive fluid A is pumped between the second volume 266 and the fourth volume 269 through a resilient washer valve. before flowing through 270 into the second volume 266 of the additive chamber at a pressure of about 900 kPa. To reduce or substantially avoid premature or excessive foaming of additive fluid A, (i.e., to reduce bubble nucleation), the pressure of foamable liquid A is increased from 900 kPa to The pressure should be reduced as gently as possible to ambient pressure. The valve seat may be of a correspondingly conical shape, and a preferred example is a circular valve seat. The cone angle may be about 45°. The diameter of the washer valve 270 is such that the foaming additive fluid A is The air flows out from between the valve 270 and its valve seat in the form of a film having a relatively large cross-sectional area. In an exemplary arrangement, additive fluid A is positioned at about 45° to the additive It may strike the wall of the fourth volume 269 of the chamber and then flow against the wall of the chamber. The diameter of the fourth volume 269 is significantly larger than the diameter of the additive inlet 244 (e.g., 1 5 times larger), the velocity of foamable liquid A is 44. In the illustrated example, the walls of the fourth volume 269 are substantially smaller than those of the outlet nozzle 26 2, and the foaming additive fluid A is injected at a relatively low speed. Converge to form a smooth, low-velocity flow.
[0080] The additive valve means 270 need not include a thermoplastic washer, and in some embodiments may include two. and a precise gap between them to allow the foamable liquid A to pass through. However, resilient washers may exhibit advantageous self-compensation for different flow rates. Furthermore, the double cone arrangement needs to be manufactured with substantially greater precision than the resilient washer. There may be a need.
[0081] A diluted (and substantially homogeneous) concentrate C in a second volume 266 in the center of the additive chamber. d is able to be mixed with the foamable additive fluid A in the fourth volume 269 even at a relatively low pressure. The fourth volume 269 is preferably open to ambient pressure and therefore at a relatively low pressure. Concentrate C d Further mixing of the foamable additive fluid A with the foamable additive fluid A is performed by dispensing the liquid through the outlet nozzle 262. The outlet nozzle 262 may be provided in a receptacle. A length of tubing may be attached to direct the liquid to a receptacle at some distance. .
[0082] 4A-5B, an exemplary pressure responsive flow control valve assembly 282 includes an elastic The valve includes an annular valve body 284 and a valve holder 286, the valve body 284 having a proximal end The valve includes a central passage 288 coaxially connecting the valve end 283 and the distal end 285 along the longitudinal axis L. The valve body 286 is configured to receive the valve body 284 and includes a generally annular side wall 289. and a seat 28 against which a distal end 285 of the valve body 284 abuts when assembled as in use. Valve holder 286 has a valve seat 287 connecting the valve seat 287 to the distal end of valve holder 286. In the particular example shown in FIG. 4A, the outlet passage 286E is 284. It is substantially coaxial with and has a larger diameter than the passage 288 through 284.
[0083] In use, a liquid (e.g., foamable additive fluid A) is introduced proximally through passage 288 in valve body 284. 283 to the distal end 285, at least the radially outer region of which is seat 2 87 and then through outlet passage 286E of valve holder 286 to the pressure responsive valve assembly When the dosing mechanism 260 is assembled for use, the valve holder The valve body 284 is resilient. and a fluid-insulating member 282 for guiding the fluid to the proximal end 283. In an unflexed state, the elastic member is configured to flex longitudinally in response to an increase in pressure. In the particular example shown in FIG. 4A, the distal end 285 of the valve body 282 is at least partly in contact with the valve seat 287. The valve element 284 is spaced from the inner annular region at least to allow passage of the valve element 284 through the passage 288. When flexed in response to fluid pressure, its distal end 285 can bend towards the valve seat 287 .
[0084] The particular example shown in FIG. 4A (disclosed in U.S. Pat. No. 7,225,829) ) the valve holder is formed in a valve seat 287 and has an annular biaxially extending outlet passage 286E. The valve body 2 further includes a pass channel 281A and a longitudinal bypass channel inlet 281B. When 84 is not bent as shown, fluid passes through bypass channel inlet 281B. 281A into the annular bypass channel 281A and then into the spaced inner distal end 281B of the valve body 284. 5 to flow into the outlet passage 286E. In this manner, fluid pressure against the proximal end 283 of the valve body 284 is applied to the annular bypass channel 2 81A is low enough to be in fluid communication with the outlet passage 286E of the valve holder 286. Bypass channels 281B, 281A are provided through which the fluid can pass. As the valve body 284 moves, its distal end 285 moves toward the inner region of the seat 285. This bends the bypass channels 281B and 281A, reducing their effective area. As a result, the pressure responsive valve assembly 282 reduces the effective area through which fluid can flow. It responds to increasing fluid pressure by increasing the fluid flux as the pressure increases. Another exemplary pressure responsive valve assembly 282 includes a valve body 28 4 and valve housing 286 have different configurations and arrangements.
[0085] The valve body 284 includes or consists essentially of a resilient rubber material and is deforms in response to increasing fluid pressure, directly reducing the effective passageway through the pressure responsive valve assembly 282. It is constructed to have a small diameter, thereby limiting the speed at which fluid can pass through it. When the fluid pressure exceeds a certain value, the size of the opening is adjusted to maintain a substantially constant flow rate. An example of a potentially suitable pressure-responsive valve is the Vernay VL3007XXXXX available from (registered trademark) TM Potentially suitable pressure response Other examples of valve trains are shown in U.S. Pat. Nos. 4,609,014, 7,222,643, and 5,422,643. It is disclosed in Patent No. 7225829.
[0086] In instances where the additive is a foaming liquid, several factors can cause premature foaming. For example, the presence of sharp edges or asperities, agitation of the foaming liquid, Nucleation of bubbles can be induced by increasing the temperature, decreasing the pressure relatively rapidly, etc. When the temperature decreases, the saturated concentration of dissolved gas decreases, causing bubbles to form. The pressure in the additive chamber can be about 690 kPa when introduced into the receptacle. Before dispensing, the temperature must be reduced. To prevent premature foaming, a foaming liquid must be added. The pressure reduction may be postponed until as close as possible to the outlet nozzle of the pressure applying mechanism. Thus, the sudden drop in pressure tends to increase agitation of the liquid. may be kept at a relatively low temperature, for example by being kept in a refrigerated environment. This prevents foaming and is also favorable for maintaining hygienic conditions.
[0087] The ability of a pressure responsive valve to reduce fluctuations in flow rate in response to changes in fluid pressure is essential for the auxiliary fluid system. The pressure of the additive fluid A supplied by the system is uncertain or varies between different systems. When the foaming additive fluid A is used, the foaming property (i.e., foaming or foaming property) of the foaming additive fluid A is reduced. This effect can be seen in the fact that increasing the flow rate of the foamable liquid reduces the This increases the risk of turbulence in the liquid, which can directly or indirectly cause foaming of the liquid. This can arise from phenomena that may cause
[0088] The dispenser head 200 is an assembly of parts that may be provided in assembly or kit form. For example, the valve housing 270, 280, flow control means 275, 285, and one or more of pressure responsive valve 282 are assembled. They may be provided as separate components that can be erected and functionally interconnected. The dispenser head 200 is provided as a unitary structure. may be provided as a fixture that can be reversibly coupled to the dilution housing 230.

For example, the end may include a mechanism 238 for connecting the additive housing 260 to the diluent housing. 230, or any other suitable threaded end. In some instances, the dosing mechanism may be an additive handheld. housing 260, additive valve housing 280, pressure responsive valve 282, and shutoff valve 285. The composition may be provided as a kit containing the composition.
[0089] The concentrated liquid C is delivered from the container 300, and the dilution liquid and the foaming additive liquids D and A are delivered to the dilution device. By controlling the time it takes for the liquid to flow into the liquid supply mechanism and the liquid addition mechanism and mix with concentrated liquid C, This allows the desired amount of beverage B to be dispensed with the desired concentration and carbonation or nitrogenation. In some instances, the pumping rate of concentrate C and / or the shutoff valve 275 and the supply valve for diluent D are The operation of the shutoff valve 285 for pressurized fluid A, and potentially other operating parameters of the pump 220, is A recipe (not shown) for that particular concentrate may be provided as part of the pump 220. It may be controlled by an RFID chip or a QR code. The head 200 reads the recipe for beverage B and selects concentrate C, diluent D, and The reader device may include a reader device capable of adjusting the ratio of the first fluid A and the second fluid B.
[0090] The dispenser head 200 may contain information about the liquid product intended for the user. , and potentially the amount of concentrate remaining in container 300, the expiration date (or "expiry date") of concentrate C. "Best Before" or "Best Before" date), concentrate and dispenser information for dispenser operators. The information may include information such as compatibility with the dispenser head. A graphic interface provided on the dispenser head 200 or This arrangement allows the dispenser head 200 to This is particularly advantageous when the container 300 is attached to a concentration container 300 for standalone use. .
[0091] The electronic processor controls the delivery rate and / or the diluent flux and / or the additive flux. and electronic input data indicating the amounts of concentrate C, diluent D and additive fluid A, and the amount of beverage B. The electronic processor may be able to process this data to The time period during which at least the diluent D and / or additives flow into the dilution chamber 232 and / or additive chamber is determined. and by outputting respective electronic control signals. Thus, it may be possible to control the operation of the shut-off valves 275, 285 independently of each other.
[0092] In some examples, the dispenser assembly including the dispenser head 200 may be radio frequency The RFID data is read and the opening and closing of the diluent and additive shutoff valves is controlled. The dispenser head's operating parameters, such as the timing of At least a portion of the electronic input data may be used to The data may be entered manually or may be included in the pump means and / or the dilution mechanism and / or the addition mechanism. may be transmitted from a sensor installed in or included in the auxiliary fluid system 400; and / or , transmitted by one or more devices such as RFID that may be included in the concentrate container 300. In some examples, the dispenser head 200 may include a concentrate container 300, or The concentrate container 300 contains the concentrate C, the diluent D, and the additive stream to provide the desired beverage B. The dispenser may be provided with means for indicating the relative proportions of body A. For example, the dispenser head may be The device may include RFID means capable of providing information.
[0093] Concentrates are, for example, beverages such as fruit juices, beer, milk, coffee, and cola drinks. In some instances, the beverage may be concentrated into various beverages, such as soft drinks. Condensate C is relatively viscous and provides the desired carbonation and nitrogen content to beverage B while avoiding excessive foaming or effervescence. To prevent this, it must be diluted before mixing with water (or other aqueous liquid) A, which contains carbon dioxide and nitrogen. Diluent D is substantially free of carbon dioxide or nitrogen added in a foamable form. may comprise or consist essentially of water (or other aqueous liquid); and and / or additive fluid A is carbonated or nitrogenized water that can effervescently ... In some examples, additive fluid A may comprise or consist essentially of In some instances, the mixture may be substantially free of carbon dioxide and nitrogen. In some cases, a foam of about 10 ... The catalyst may be configured to promote controlled nucleation.
[0094] The user may need to manually pour beverage B directly into a cup in a relatively short time. At this time, beverage B may be expected to be dispensed into a cup or other receptacle. To do this, concentrate C flows from the pump through outlet nozzle 262 into a receptacle. When beverage B is made from apple juice or other beverages, concentrate C must be diluted and carbonated. In some instances, such as with fruit juice, concentrate C may have a relatively high viscosity. before being mixed effectively with carbonated fluid A in a sufficiently short time. It is necessary to dilute it with D. A sufficient amount of diluent D, such as still water, is mixed with the juice concentrate C to obtain a charcoal-based solution. Diluted concentrate C so that acid water A can be mixed quickly enough for convenient dispensing. d of The viscosity may be reduced significantly.
[0095] In some instances, concentrate C (e.g., a concentrated syrup for a cola drink or beer) is carbonated water. It has a low enough viscosity that it does not need to be diluted before blending with aqueous liquids such as nitrogen water. In such a case, the diluent shutoff valve 275 may be closed while beverage B is being dispensed. For example, you can mix cola syrup with carbonated water in a ratio of about 5:1. Some alcoholic beers may be mixed at a 4:1 ratio, and some non-alcoholic beers may be mixed at a 4:1 ratio. For drinks, the ratio of concentrate to carbonated water may be about 25:1.
[0096] The auxiliary fluid unit 400 is configured to pump water approximately 200 times the volume of the water immediately before it is introduced into the dispenser head 200. ° C. and pressurized to about 700 to 1000 kPa. When carbonated water A is introduced into the adding mechanism 260, the content of dissolved carbon dioxide is practically reached. This can be close to the highest level possible.
[0097] The additive flow path 430 for transporting the carbonated liquid or nitrogen liquid A is configured to introduce the carbonated liquid A into the adding mechanism 260. The design promotes laminar flow as much as possible to reduce or prevent foaming during The laminar flow may be achieved by arranging the additive duct 430 so that it changes direction gradually without sharp corners. This can be facilitated by structuring the
[0098] Carbon dioxide (or nitrogen) bubbles nucleate in response to the pressure drop when carbonated liquid A enters the addition mechanism. The addition mechanism provides a constant pressure reduction rate to prevent gas bubbles from forming. The carbonated liquid A may be configured to control the rate of generation of bubbles and the size distribution of bubbles. The number and size distribution of the particles flowing into the dosing mechanism are controlled to promote controlled foaming of the beverage. The gauze may be threaded as it is being fed or as it passes through the dosing mechanism.
[0099] In some instances, the disinfectant solution may be diluted when the dispenser head 200 is not in use. and introducing the dispenser head 200 into the mechanism or dosing mechanism, and It may be advisable to use diluent to clean the outlet nozzle during mixing. There may be cases where this is the case.
[0100] The auxiliary fluid system is configured to keep the diluent D and additive fluid A at the same or different temperatures within a range of about 1°C to about 10°C. The fluid A is cooled to different temperatures and at least the added fluid A is added at a pressure of about 600 kPa to about 1000 kPa. It may be one that can be applied with force.
[0101] In some instances, the auxiliary fluid system may be configured to carry a carrier liquid, such as water, that is carbonated or nitrogenated. Carbon dioxide or nitrogen gas bubbles are introduced so that substantially all of the gas in the bubbles dissolves in the carrier liquid. The gas-containing carrier liquid is treated to dissolve or suspend the foamable (i.e., foamable) additive. The auxiliary fluid system may be configured to provide a gas-containing carrier liquid. By passing it through an exchanger, the temperature is lowered to just above its freezing point, and the carbon dioxide in the carrier liquid is removed. The saturated solubility of hydrogen or nitrogen may be increased by using the same type of liquid as the carrier liquid (e.g., static water). The diluent is passed through the same heat exchanger, which may be a twin coil heat exchanger, to increase its temperature. Then, the diluent and additive liquids D and A are introduced into the diluent inlet 23 at separate flow rates. 4 and the additive inlet 264. The concentrated solution C is cooled and supplied to the additive inlet 264. D, resulting in rapid dilution and subsequent cooling of the foaming additive fluid A. Diluted concentrate C with sufficiently low viscosity for mixing d can be generated. The foaming additive liquid A is diluted with concentrated liquid C in the additive chamber. d It is relatively mildly blended with and the sparkling beverage B is dispensed directly into a cup without excessive fizzing.
[0102] When a foaming gas is introduced into the carrier liquid to supply a foaming additive liquid into the auxiliary fluid unit, In this case, the pressure difference between the gas (e.g., carbon dioxide or nitrogen) and the water or other carrier liquid is generally In addition, it can be important to dissolve the gas effectively and quickly in the carrier liquid. If the pressure of the acid gas is 700 kPa and the pressure of the water is 200 kPa, the pressure difference is 500 kPa. For example, after the water carrier liquid is saturated with carbon dioxide, the risk of excessive foaming is reduced. In order to reduce the pressure, it is practically possible to reduce the pressure from 700 kPa to atmospheric pressure at the time of dispensing. This is because the flow rate of the liquid is relatively low at the point where it is dispensed. For example, a long tube with a relatively small diameter, or a tube with a slight taper from small to large diameter, This can be achieved by transporting the foamable liquid through a tube. The foaming liquid is transported through a relatively short tube with a large diameter, and a flow control valve is attached to the outlet nozzle. The dissolved gases immediately turn into concentrated liquid when passing through the flow control valve. or mixed with a pre-diluted concentrate. The concentrate is denser and therefore contains more dissolved gases. can be absorbed.
[0103] Generally, excessive foaming and effervescence occurs when foaming liquids are mixed too vigorously with concentrates. In general, it is recommended to avoid stirring the foaming additive liquid as much as possible, as this may cause The dispenser head of the particular example includes a step of actively diluting concentrate C. , and the step of gently mixing the foaming liquid A with the foaming liquid B is separated to produce a foaming beverage B with reduced foaming. Furthermore, the present invention has the advantage of providing an in-line means for dispensing the auxiliary fluid sufficiently quickly. The system 400 can be used to produce different beverages B from different respective concentrates C. In this case, beverage B can be quickly switched off while substantially reducing the risk of cross-contamination. For example, a dispenser connected to a container containing a first concentrate may be used. The first assembly with the head can be relatively easily and quickly disconnected from the auxiliary fluid system. and replacing it with a second assembly of a dispenser head and a container containing a second concentrate. It is possible.
[0104] In some instances, the dispensed beverage may be highly effervescent (i.e., very "fizzy"). It may be desirable to mix a relatively large amount of foaming liquid with a concentrate. Generally, the more concentrated the concentrate, the more foaming it will have. In general, the higher the concentration of the concentrate, the higher its viscosity. In general, the preferred offering of chilled beverages is The temperature at which the concentrate is delivered may be approximately 8°C (5-10°C), and concentrate C may be stored in a refrigerator at approximately 6°C. Since the cup is likely to be at ambient temperature (approximately 15-30°C), the auxiliary fluid unit The diluent should be introduced at a temperature close to its freezing point, e.g., about 2°C for a water diluent. The foaming additive liquid may contain as high a content of dissolved foaming gas as possible. .
[0105] In some instances, the ratio of concentrate to hydrostatic diluent may be about 1:1, with sparkling water and diluent being about 1:1. The ratio of diluted concentrate may be about 4:1.
[0106] The viscosity of the diluted concentrate is determined by the final stage of mixing the foaming additive fluid with the diluted concentrate. It may be low enough so that it can be done in the cup after it has been opened.
[0107] For a given pressure difference between the gas and the liquid, a given temperature, and a given time, the maximum saturation level The dispenser head uses this known constant value to dispense concentrate, dilute It may also be possible to dispense the correct ratio of diluted solution to saturated carbonated water.
[0108] Some exemplary dispenser heads are supplied with concentrate by an auxiliary fluid unit. and / or by using diluents such as still water, thereby avoiding the occurrence of cooling and / or pressure. Alternatively, it may have an aspect that only an additive fluid such as carbonated water or nitrogen water can be transported. The dispenser head, which includes or is connected to a concentrate container, dispenses diluents and / or additives. The auxiliary fluid unit is connected to the dispenser head so that the added fluid can be transported from the auxiliary fluid unit to the dispenser head. The type of beverage dispensed can be controlled by connecting the dispenser head to the auxiliary fluid unit. and attached to or attached to a container containing a different concentrate suitable for the desired beverage. It can be changed by attaching a different attachable dispenser head. Remove the concentrate container from the pump and connect another container containing the desired concentrate to the pump. This eliminates the need to clean the auxiliary fluid unit to remove residual concentrate. This avoids cross-contamination of the desired beverage with residual amounts of the previous concentrate. A typical dispenser head distributes disinfectant solution through all passages downstream of the pump outlet. The diluent inlet is adapted to allow a source of disinfectant solution to be connected to the diluent inlet for introduction. Good too.
