Description

The apparatus and method of rapid comestible fluid dispensing

Invention field

The present invention is usually about the fluid escaper, particularly about fluid food escaper and its cooling, sterilization, measurement and pressure control device.

Background of invention

Although it is made a lot of improvement in fluid exhaust system and the device, still unresolved over past ten years about the problem that exists in this device and the system.These problems are present in the application of many different fluids dischargings, but below will be described in the special influence of fluid discharging apparatus and system in the Food ﹠ Drink industry.As can be seen, the fluid food escaper in this industry can be used to discharge various carbonic acid, no carbonic acid is premixed and the beverage that mixes, comprise as beer, soda water, water, coffee, tea or the like.Fluid escaper in this industry also is usually used in discharging on-beverage class fluid, as seasonings, food composition etc.Here used " fluid food " in used and the claims but refer to the Foods or drinks of waiting to consume and be liquid form of any kind.

Long-standing subject matter is the emission problem when being used for soda aspect the fluid food draining technology.At first, because the fluid of pouring out is a carbonic acid, therefore very sensitive to pressure drop, traditional carbonic acid fluid food escaper flows very slowly usually, needs the several seconds just can fill up the cup or the glass of a general size.Secondly, when flow velocity increased, the beverage of discharging usually had the top (this can overflow, spreads out or produce dirt) of undesirable a large amount of foams, and often makes the food singsong because of quick drain.Some conventional device adopt fluidstatic pressure to make fluid food release the preservation jar that is positioned at the discharge side top, disclose a kind of such device in the U.S. Patent number 5603363 of authorizing Nelson.Unfortunately, these devices can not provide pressure control in the exit, are preventing to form aspect foam and the beverage loss the limited in one's ability of it under carbonic acid fluid food situation.The operating potential of the stand pressure in this device has been wasted greatly owing to hydrostatic pressure.Owing to can not keep the stand pressure to outlet in these devices, the carbonic acid fluid food can lose its carbonate gas inevitably when waiting for next discharging.In addition, as other existing beer escaper, these devices adopt the very low method of efficient to come the feedway of cooled containers and fluid food.

Another problem of traditional fluid food escaper and this fluid are relevant with the temperature of fluid when drinking before discharging.Some beverages are drunk after the cooling usually, but do not ice in the beverage, therefore must keep cooling or freezing before discharging.This requirement has just added many design limit on the escaper of this class beverage of discharging.As an example, the beer cooling is drunk, therefore must freezing or cooling before discharging.Traditional way is in freezing and heat-insulating storage area cooled beer.The method efficient of cooled beer storage area is low and cost is high in the uncertain time before the beer discharging.This cooling can't provide quick temperature control and the temperature traverse for the treatment of comestible fluid dispensing.Particularly since the fluid food that stores amount is quite big usually, this just can not be changed fast and regulated temperature by the user.In addition, traditional not quite suitable control with the automatic or manual of refrigeration system of refrigeration system carried out the fluid food temperature controlling.

With great majority other do not need to cool off (as soft drink, tea, lemon juice etc., they can mix with ice in container after the discharging) or do not need the fluid food of cooling mechanism or system different at least and on the fluid line between refrigeration stream body source and outlet, tap or the discharging rifle, beer is preferably on emission point all can keep cooling.Therefore, a lot of traditional escapers should not be used to discharge beer.For example, the beer in the fluid line between refrigeration stream body source and outlet, tap or discharging rifle can become temperature between twice discharging.It is warm that beer in these pipelines drinks, and it can mix with the cold beer that flows out after the warm beer in the fluid line, or releases and emit.This situation is unacceptable, because these products are called as the product that waste product maybe can not meet the demands.In addition, because a lot of fluid foods can be very fast rotten, preserve these uncooled fluid foods (as the food pipeline) for a long time and can make fluid rotten even pollute member or whole exhaust system, thereby require total system is cleaned from the refrigeration stream body source to outlet, tap or the jetting gun.

Because a lot of fluid foods until emission point all need keep cooling, have constituted very big restriction for reaching desired device of this cooling and member to traditional escaper design.Therefore, the escaper of the perishable fluid as beer has immovable tap usually, these taps are linked on the refrigeration stream body source by pipeline heat-insulating or refrigeration, and the escaper of less rotten fluid (particularly those available ice-cooled fluids after discharging) can be held and move with hand, if desired, they are by in the fluid that is connected to refrigeration source with not heat-insulating fluid line or does not freeze that does not freeze.

The design objective of a fluid food escaper relevant with the problems referred to above is to clean when needed and the ability of the escaper of sterilizing.As the problems referred to above, can not suitably clean the smell that ejector system can influence fluid food, even can make fresh fluid food rotten.Owing to can not suitably clean and one or more interior zones of the ejector system of sterilizing, therefore the design of a lot of potential ejector system can not be adopted.Especially adopt the part that has little, inaccessible finding or have little interior zone when ejector system design, they can not clean at an easy rate with purging method, and the advantage that this design may provide is because cleaning requirement and can't accomplishing.

Above-mentioned all problems all has a significant impact the quality and the taste of fluid discharged food, and also has a key factor that works in most escaper is used: speed.Since can not adopt known devices increase liquid stream, because the carbonic acid fluid demands special care on its discharging modes or since from perishable fluid to the restriction of escaper design-calculated, traditional fluid food escaper flow velocity certainly is slow and efficient is low.

Because problem and restriction in the above-mentioned prior art, just need a kind of tapping equipment and method of fluid food, it can come rapid comestible fluid dispensing in check mode, even also can not bubble in the long period between twice discharging or remove carbon dioxide; It can make whole fluid by tapping equipment keep cooling chronically and expeditiously; It can adopt the control setup of automatic or manual refrigeration system to come fluid discharged food is carried out rapid and precise temperature control; It can make the form of installation or hand-held device; Inaccessible interior zone also can clean and sterilize at an easy rate even exist quite little in device; But it is the operation and the discharging parameters such as control blowdown presssure, flow velocity and head size of monitor unit also.Each preferred embodiment of the present invention can reach one or more The above results.

Summary of the invention

The present invention solves problem in the above-mentioned prior art by a nozzle component is provided, this nozzle component can be controlled the pressure of the fluid food that nozzle component has, a refrigeration system adopts the refrigerant pressure of refrigeration system to control the fluid food temperature controlling that provides effective and good, one type H Exch connects the fluid food that leads to the discharging nozzle exit with cooling in one way, decontamination system is in order in the fluids for sterilization food exhaust system effectively, outside, or even inaccessible position, hand-held fluid food escaper can cool off and selectively discharging be fed to a kind of of wherein multiple fluid food.

The invention solves the pressure that how to adopt the fluid food frame as the pressure of whole exhaust system and emission problem (especially in the soda system as the beer exhaust system, it is very unnecessary keeping the pressurization to soda between twice discharging for a long time) can not occur as issuable elevated pressures.In one embodiment of the invention, the nozzle component of comestible fluid dispensing has valve, each valve have with spout discharge aperture on the corresponding open position of pressure of different fluid foods and the off position of certain limit.Control cock causes the controollable blowdown presssure that reduces to strengthen fluid holding chamber in the nozzle component or container before opening.This valve preferably is the plunger valve of telescopic relation with nozzle shroud.Replaceability embodiment of the present invention has adopted other step-down member and device to control blowdown presssure on the jet pipe.For example, a vent line can extend to spout assembly from the fluid line of nozzle component or supply fluid food.By will be a certain amount of discharging from the fluid food of jet pipe or fluid line, system controller can drop to the pressure of the fluid food in the jet pipe on desired and the controollable emission level before jet pipe is opened.Other embodiment of the present invention adopt the wall of fluid line movably, deformable fluid chamber wall or the like to control the pressure of the fluid food on the jet pipe.Can adopt the pressure sensor of control jet pipe valve events and/or the control system of flow-rate meter to measure and monitor mobility status, can make the user monitor the discharging of fluid food when needed thus and expend situation.

In order to improve the temperature control and the cooling effectiveness of exhaust system, the present invention preferably adopts the H Exch near nozzle component, does not have big framing member to stop up between H Exch and its corresponding nozzle component.Preferably adopt plate heat exchanger efficiently, because their efficient is higher and size is little.In H Exch, can adopt a blow and vent system or fill in the front space that may exist of ventilating or filling with it, can avoid the problem of cleaning and pressurizeing and discharging thus.Because the position of H Exch is near nozzle component, therefore it can produce convection circulation, by nozzle component cold fluid food is delivered to the terminal part of nozzle component, and, therefore all can make fluid food keep cooling up to each nozzle component discharge side at the warm fluid food of this reception.The invalid refrigeration source of the fluid food in potential long-time between twice discharging because fluid food near emission point place cooling, can be removed by the advective cooling of heat-insulating storage area in a lot of application the in addition.

If desired, the present invention also can adopt the form of discharging rifle, and the manoevreability and the mass rate of emission of discharging jet pipe can be provided thus.The preferred embodiment of discharging rifle has a H Exch, and its close nozzle component is to produce cooling convection circulation as discussed above in nozzle component.In order to increase the ability that portability and user handle the discharging rifle, this H Exch is a kind of efficient heat exchanger as plate heat exchanger.This discharging rifle can have a plurality of fluid food input ports.Therefore allow the user can discharge a kind of of multiple fluid food selectively.What a valve is contained between the nozzle component of H Exch and discharging rifle, and this valve can be controlled by the control setup on the discharging rifle by the user, is fed to wherein any fluid in order to discharging.Nozzle component as described above is the same with H Exch, and the requirement of cryogenic fluid food in a lot of the application has been eliminated in the position of H Exch near emission point.In addition, the pressure control of jet pipe is preferably undertaken by the nozzle component valve of the off position with aforesaid certain limit.

In order further to improve the control of convection cell food temperature, the present invention preferably has one can be by controlling the refrigeration system that refrigerant pressure and/or temperature are controlled.An evaporator pressure regulating control especially can be used for controlling the refrigerant pressure of upstream of compressor in the refrigeration system, thus the cooling power of refrigerant and the temperature of control by the refrigerant of H Exch in the may command H Exch.In addition, hot gas bypass valve can be introduced the refrigerant from the heat of compressor in the cold refrigerant of H Exch again, control the cooling power of H Exch and the temperature of the fluid food of control by H Exch thus, this valve is particularly useful for refrigeration system and is in situation under low load or the 0 load operation condition (situation when being cold as the fluid in H Exch between the uncommon discharging).

In the preferred embodiments of the present invention shown in Fig. 1 and 2, shown discharging rifle 16 also is connected on the bucket 22.That is discharging rifle 16 or nozzle component 40 (not shown) will provide the beer from bucket 22.Though by switch 32 both are linked on the same bucket 22 as shown in Figure 2, this layout is only with the purpose that explains and simplify.Beer from bucket 22 is supplied with discharging rifle 16 by fluid line 42, only can see in these pipelines in Fig. 2.More particularly, discharging rifle 16 preferably has a plate heat exchanger 44, and fluid line passes it and is connected by the fluid input port in a conventional manner.A fluid outlet (below will describe in detail) is linked H Exch 44 nozzle component 46 of beer rifle 16.This H Exch 44 also has traditional opening and joint in order to connection input and output refrigerant lines and posture H Exch 34.

Goodsshelves 10 shown in the figure also has a refrigeration system (be shown 48 usually, and will describe in detail below), in order to the inside of cooling Goodsshelves 10 and the refrigerant of cooling heat exchanger 34,44.For refrigerant being supplied with H Exch 34,44, traditional refrigerant lines 50,52 is led to H Exch 34,44 respectively from refrigeration system 48, and joint and the opening known by those skilled in the art are connected on refrigeration system 48 and the H Exch 34,44.Equally, traditional refrigerant return line 54,56 stretches out from H Exch 34,44 respectively, is connected on coolant system 48 and the H

Exch

34,44 by traditional joint and opening.

In order to make bucket 22 and to be connected fluid food and

refrigerant lines

30,42,50,52,54 and 56 coolings, Goodsshelves 10 inside are preferably heat insulation in a conventional manner.For operating in Goodsshelves 10 outside fluid lines 42, when not using, discharging rifle 16 preferably these pipelines are not placed in the Goodsshelves 10 to discharging rifle 16.Particularly, fluid line 42 can be attached to a roll device or any other traditional pipeline takes up on the device (not shown), and when discharging rifle 16 turned back on the retainer 58 on the Goodsshelves 10, it was moved fluid line 42 in the Goodsshelves 10 to.Concerning those skilled in the art, these devices and operation are all known, and therefore have not been further described.

Referring to Fig. 3, the existing mobility status that passes beer of the present invention of describing in detail.As here with in the claims being adopted, term " fluid line " refers to from fluid source (for example bucket 22) generally to zone that exhaust outlet 70,130 fluids pass through." fluid line " can refer to that fluid passes through whole path or a part of path of this system.

As mentioned above, diffuser 30 leads to posture H Exch 34 from each bucket 22, and links in a conventional manner on the fluid input tube line of posture H Exch 34.Diffuser 30 preferably is equipped with valve 60, is used to have at least selectively limit, preferably close selectively diffuser.For simplicity, the shrinking valve that valve 60 is preferably traditional, but also can adopt film valve or any other valve that can close and open diffuser 30 rapidly.Valve 60 can resemble a lot of shrinking valves used be contained in diffuser 30 tops, also can be spliced on demand in the diffuser 30.

As mentioned above, fluid output tube line 30 leads to each nozzle component 40 from posture H Exch 34.Export pipeline 38 and bonded assembly nozzle component 40 are posture H Exch 34 extensions on its fluid egress point (not shown).A vent line 62 preferably stretches out from export pipeline 38 or nozzle component 40, as shown in Figure 3, and is connected in a conventional manner on export pipeline or the nozzle component.Vent line 62 preferably is equipped with exhaust-valve 64, can close exhaust-valve 62 selectively.Exhaust-valve 64 preferably also is a shrinking valve, but also can be other any valve of describing with reference to the valve on the diffuser 30 60 as top.As will be in greater detail, nozzle component 40 supplies with the beer of automatic heat-exchanger 44, and it can carry out opening and closing, to discharge beer selectively.

Nozzle component 40 (see figure 4)s comprise that 66, one on a cover is movable to the valve 68 that opens and closes exhaust outlet 70 and fluid holding chamber or container 80, and it is at least by the part of cover 66, preferably determined by a part and the valve 68 of cover 66 at least.Cover 66 is as shown in the figure slender body preferably.For the following reason that will narrate, the shape of cover 66, valve 68 and exhaust outlet 70 is preferably made and allows valve 68 to move a segment distance with telescopic relation in cover 66.In illustrated embodiment, cover 66, valve 68 and exhaust outlet 70 have the shape of round section, therefore, have determined a tubular inner zone in cover 66.Valve 68 is as shown in Figure 4 plunger piston type valve preferably, wherein can provide in the position range that valve 68 passed through before arriving open position covering 66 the wall or the sealing of inwall (shape that depends on cover 66).Therefore though in this valve, an open position is possible, valve 66 best removable open positions by certain limit can provide the exhaust outlet 70 of different size and the flow velocity of the respective range that flows out from exhaust outlet 70.For 68, valve rods 72 of start valve are contained in an end of valve 68, and pass cover 66 and reach and preferably be attached to the actuator 74 of cover on 66.Actuator 74 is preferably controlled in a conventional manner by user or system controller 150, valve 68 is positioned on the diverse location in the certain limit in the cover 66.This position range comprise at least one discharge side 70 open with the open position of discharging beer and determine along cover 66 length, discharge side 70 closes the scope with the off position that prevents the beer discharging.Those skilled in the art it will be appreciated that the cover 66 of whole nozzle component 40 is not necessarily elongated or tubulose.(other outlet member that describes below also can play the effect of plunger piston type valve 68 when adopting preferred plunger piston type valve 68, as following the discussion), the cover that only contacts with valve 68 part provides fluid-tight in the scope of valve-off position, they should be elongated, tubulose or have a long-pending chamber of constant cross-section along its length.

Actuator 74 is compressed-air controlled preferably, and it is preferably by supplying with pressurized air from pneumatic engine (not shown), compressed air tank (also not shown) or from traditional pipeline and the joint of linking the jar 24 on the pressurized keg 22.Those skilled in the art 66 move valve 68 to open the said function of exhaust outlet 70 with respect to cover for finishing as can be seen, can adopt multiple other acting device and assembly.For example, actuator 74 needn't all have external impetus opening and closing on corresponding two positions of stretching and contracting with outlet valve 68, actuator 74 can have external impetus (for example extended position of opening towards outlet valve 68) in a direction, and is pressed in the opposite direction by the mode that the beer of the pressurization in the nozzle component 40 is known with those skilled in the art.As another example, pneumatic actuator 74 can be used by gear (as with the scroll gear of the wheel tooth rotation valve rod 72 on valve rod, the rack rails and miniature gears group etc.), magnetic force and wait the electronic or hydraulic actuator of movement of valve or mechanical actuation device to replace.At this on the one hand, valve 68 needn't install on the valve rod 72 and by valve rod and move.Existing multiple other valve start member and assembly can be used to movement of valve 68, thereby opens and closes exhaust outlet.Yet start member under all these situations and assembly be controollable preferably, and it can make valve 68 move on on the position of certain limit on the needed position of covering in 66.These other start assembly and member also falls in the spirit and scope of the present invention.

In the embodiment of special recommendation of the present invention, SP Start Pickup 76 and closure sensor 78 are contained in out the top of mouth mask 66 or at the top (as shown in Figure 4) of valve 68.Two

sensors

76,78 are linked on the system controller 150 in a conventional manner, also stop the discharging of beer when needed from nozzle component 40 discharging beer in order to control cock 60,62,76.SP Start Pickup 76 preferably responds the starting device of the machinery that touches, and closure sensor 78 is optical sensors, and its responds the optical detection of beer or is immersed in the beer.Certainly, available a lot of other known machineries and electronic sensor are delivered to system controller 150 with signal, thereby open and close the valve 68 of spout assembly 40.These sensors comprise but are not limited only to proximity sensor, movable sensor, temperature sensor, liquid sensor or the like.Yet used sensor (the especially such mechanical pick-up device of the SP Start Pickup in the preferred embodiment of the present invention 76) should be hanked and can operate with the shape of various beer containers and container.For example, when the SP Start Pickup of selecting is when operating by the bottom surface of surveying beer container, this sensor should be able to be surveyed the bottom surface of various types of beer containers, includes but are not limited to flat, oblique, opaque, transparent, reflective, opaque or the like surface.

In the beer emissions operation, the user is placed on below with the nozzle component 40 of needed beer type with a glass or such container of mug, rise container, rise to always and can start SP Start Pickup 76 (under the situation of the hand starting sensor of recommending, preferably starting) by contacting with container bottom.In when starting, SP Start Pickup 76 is given system controller 150 (as along valve rod 72 upwards, from actuator 74 or cover 66 and come out and arrive system controller 150 by arrangements of electric connection with a signal; Leave cover and 66 upwards arrive system controller 150 again, or the like) or transmit the wireless signal of a common mode, this signal is by system controller 150 receptions.System controller 150 responds, and closes from the valve 60 on the diffuser 30 of bucket 22.In this stage, the pressure of bucket 22, diffuser 30, H Exch 34, export pipeline 38 and nozzle component 40 contained beer near or equal pressure in the bucket, from nozzle component 40 discharging beer, this pressure is too big for suitably.Therefore, preferably according to the type of the characteristics that will discharge (volume of beer as requested) and the beer that discharged, the pressure of nozzle component 40 is dropped to needed amount, available several different methods reduces the pressure on the nozzle component 40.

For example, system controller 150 can send a signal to exhaust-valve 64, to open this valve beer is discharged vent line 62.The such signal of valve control response is known those skilled in the art, therefore has not been further described here.Exhaust-valve 64 is preferably opened when sufficiently long the enough beer of chien shih and is emitted, to reduce the pressure in the nozzle component 40.Exhaust-valve open the needed time depend on desired step-down amount at least in part, the type of the beer that discharged and the size of vent line 62 and exhaust-valve 64.System controller 150 is preferably the needed time pre-set program of the desired pressure drop of dissimilar beer.Therefore user's type of entering beer that will discharging with control setup 20, this moment, system controller 150 dropped to pressure with reference to the needed time of the pressure drop in the nozzle component 40 enough lowly, discharged to carry out suitable beer.After the pressure of nozzle component 40 fully reduced, system controller 150 transmitted a signal to exhaust-valve 64, to close this valve, sent a signal simultaneously to actuator 74, to open outlet valve 68.

As another example, pressure in the nozzle component 40 can come step-down by the some parts that strengthens contained beer zone, though can strengthen by overstriking fluid line or a part of H Exch 34 (as moving wall or the surface of determining a fluid line or H Exch 34 parts), had better strengthen fluid holding chamber 80.Therefore, valve 68 can move, thus the size of the fluid holding chamber 80 in the cover 66 of increase nozzle component 40.This valve is preferably determined the face or the wall of fluid holding chamber.As discussed above, valve 68 preferably can move past the off position of the nozzle component 40 of certain limit, and is preferably in cover and is telescopic relation in 66.When system controller 50 is received cranking signal from SP Start Pickup 76, this system controller 150 sends a signal to actuator, valve is shifted to exhaust outlet 70, should move the volume that has increased the fluid holding chamber 80 in the nozzle component 40, therefore reduced the pressure in the nozzle component 40, before valve 68 arrived exhaust outlet 70 and opens with discharging beer, the pressure in the nozzle component had dropped on the desired blowdown presssure.

Also has the pressure before a kind of common dropping equipment and assembly can be used to reduce discharging in the nozzle component 40.For example, the wall of one or more definite fluid holding chambers 80 can move to enlarge the fluid holding chamber, the center of fluid holding chamber 80 can laterally be shifted to and move apart to one or more telescopic walls before outlet valve 68 moves like this, and deformable fluid holding chamber 80 (as the flexible wall of tubulose flexibility) has increased the volume of fluid holding chamber 80 grades.As an example, can form this wall in spherical component, they are subjected to the limit bundle of belt, hawser or other connecting element usually, unclamp before discharging to increase the volume of fluid holding chamber 80.Concerning those skilled in the art, other known device and assembly are all packed within the spirit and scope of the present invention.

Should see, can adopt dropping equipment that the outlet blowdown presssure is dropped to needed level more than one.For example shown in Fig. 3 and 4, nozzle component comprises vent line 62 and exhaust-valve 64 assemblies, also comprises telescopic outlet valve 68.Common only such device is essential in the practice.Therefore, adopt the preferred telescopic nozzle component shown in Figure 4 and 5 mostly, just needn't adopt or remove vent line 62 and exhaust-valve 64.In addition, when employing vent line 62 as shown in Fig. 3 and Fig. 4 and exhaust-valve 64, the off position that can require valve 68 to have certain limit, in other words, valve 68 can have one simply and open and a position of cutting out.According to the work speed of down block and device and the mass rate of emission of nozzle component, even can remove from the valve 60 on the diffuser 30 of bucket 22.Particularly owing on nozzle component 40 or near the low pressure of locating, just needn't reduce the fluid pressure of the upstream of posture H Exch (as in diffuser 30) with a certain distance from the common pressuring droping lag that occurs on the nozzle component.Can allow the user on nozzle component, to discharge beer before when the high pressure of H Exch 34 upstreams passes to nozzle component 40 in pressure drop enough fast on the nozzle component 40, therefore just needn't start the pinched valve on the diffuser 32 or remove this pinched valve with needed blowdown presssure or the pressure that is close with it.

The pressure that reduces on the nozzle component 40 before discharging can carry out with above-mentioned different mode, comprises the preferred valve system shown in the employing figure.Although this exhaust-valve is preferred, also can adopt other common various valves to replace (including but are not limited to pinched valve, film valve, ball valve and guiding valve etc.), wherein can adopt the dropping equipment of one or more above-described replacements.

At system controller 150 signal is delivered to actuator 74 with when opening outlet valve 68 or shortly after that, system controller 150 also preferably starts closure sensor 78 (if also being not activated).This closure sensor 78 is preferably hanked and can be surveyed the height of outlet valve 68 or go out on mouth mask 66 ends or there is situation near the liquid it.Roughly the surface of closure sensor 78 by beer in the exploration vessel, survey its situation of immersing in beer container, survey and remove the corresponding temperature traverse of beer from sensor and wait and carry out this function.Yet closure sensor is preferably used up the situation of immersing of surveying it in the mode of knowing in the fluid Detection Techniques.

As long as system controller 150 is not received the signal from closure sensor 78, this system controller 150 allows beer to pour out from nozzle component 40.The outlet of the preferred embodiment of the present invention is the following outlet of injecting in surface, that is to say that beer injects the beer that has given off of container.Owing to adopted the outlet valve 68 of the preferable shape shown in Fig. 3 and 4, beer is discharged outlet 70 rapidly on all directions of container, and therefore, this is than the direct discharging pressure of dispense beer (help to reduce the carbonate gas loss and produce bubble) preferably.But, should see that need not to be the radioactivation stream of all directions from the beer of exhaust outlet, it can be linear flow, fan or any other needed shape.After a certain amount of beer was originally poured container into, the top of nozzle component 40 preferably remained on below the beer surface in the container.Therefore beer that add, that drain into container injects with the form of less foam after, also can reduce the carbonate gas loss.When the user entered container with beer, the user made container reduce from Exhaust assembly 40, and closure sensor 78 detects it and has not been immersed in the beer, therefore in normal way a signal is delivered to system controller 150.After receiving this signal, 150 pairs of actuator 74 of system controller are sent a signal, make outlet valve 78 turn back to off position, seal exhaust outlet 70 thus and stop the discharging of beer.

By adopting above-mentioned nozzle component, can keep-up pressure 68 the total system from bucket 22 to outlet valve, particularly the state of equilibrium of system is the pressure store (or " posture pressure ") that pressure equals beer in the bucket substantially.This pressure of total system is because lower or barometric pressure just can prevent the carbonate gas loss; Also can prevent from promptly to discharge beer, and can control discharging preferably because nonconforming high pressure produces excessive carbonate gas.

There are multiple replaceable unit in SP Start Pickup 76 and closure sensor 78 on the nozzle component that is used for controlling the beer discharging.For example, nozzle component 40 can come direct control with control setup 20 by the user, and in the case, the user preferably directly specifies the start and stop time of beer discharging.Another example when being known as the container dimensional of beer discharging, this information can be by the user by control setup 20 direct input system controllers 150.In operation, by the button that passes through on the control setup 20 of user's start as discussed above, start this system by SP Start Pickup 76 such SP Start Pickup, thereby begin to discharge beer, the mode of knowing with those skilled in the art by near one or more sensors that are positioned at the nozzle component survey outlet 14 belows container have a situation.When having discharged the beer of requirement, can stop discharging in every way, these methods are as adopting the closure sensor of closure sensor 78 discussed above, near one or more nozzle component 40 sensors that are positioned at are used for exploration vessel from exporting the situation that the below is removed, measure the flow that flows through flow-rate meter with any locational flow-rate meter that is positioned at from bucket 22 to outlet valve 68 (are preferably in exhaust outlet 70 or covering 66), or adopt any position that is positioned at equally along system along total system, but be preferably in the pressure that common pressure sensor on the nozzle component 40 is measured the beer that is discharging.In both cases, the size of nozzle component is known and preferably enrolls in normal way in the program of system controller 150.For example,, flow through the flow of flow-rate meter, should know the cross-sectional area of flow-rate meter upper outlet 14 for calculating if adopt flow-rate meter.If adopts pressure sensor for calculating the flow of time per unit by exhaust outlet, should be known the size of exhaust outlet 70 when outlet valve is opened.When adopting timer 152, best and system controller 150 connects together, (as the available flow velocity of fluid discharged amount divided by the unit time that need) system controller 150 can send a signal to actuator 74 after having pass by with needed fluid quantity discharged time corresponding, to close outlet valve 68.Because pressure and flow velocity change in emissions operation, an alternative embodiment adopts flow-rate meter and pressure sensor to monitor beer stream and pressure respectively continuously, comes to revise flowing velocity in the ordinary way in good time.When measuring volume of beer with flow-rate meter or pressure sensor, 150 pairs of actuator 74 of system controller are sent a signal to close outlet valve 68.

The device and the system of calculated flow rate discussed above are known those skilled in the art, and they all fall in the spirit and scope of the present invention.But, should see that this class device and system are not to use concerning above-mentioned outlet valve 68, the beer that they can be used to control nozzle component 40 is supplied with.For example, this device and system can be used for being positioned at posture H Exch 34 upstreams on the valve of valve 60, control with this fluid of nozzle component 40 supplied with, itself preferably is timed to and opens and closes or near time of the opening and closing of upstream valve.No matter install or system opens the time (as above-mentioned pressure sensor example) or with known cross-sectional area measurement flow rate (as above-mentioned flow-rate meter), all can adopt the by-pass valve control without outlet valve 68 to come to give off needed volume of beer from nozzle component 40 based on valve.

Also have a kind of method, in the method, can be by the valve as valve 60 of closing nozzle component 40 upstreams, all fluids that give off valve 60 downstreams after closing, discharge needed volume of beer with this from nozzle component 40.Valve 60 can be placed on the position of nozzle component 40 enough distances, is a known set amount from the volume of beer of valve 60 by nozzle component 40 like this, as 12 ounces, 20 ounces or the like.By shutoff valve 60 and blowoff valve 60 fluid downstream, just discharge known quantity of fluid from nozzle component 40.Shorten the distance of the fluid line between valve 60 and the nozzle component 40 if desired, can on fluid line, establish one or more fluid cavity (not shown), emptying when this chamber is closed at valve 60 with known volume.In addition, can adopt a plurality of valves 60 on the diverse location that is positioned at nozzle component 40 upstreams, each discharges different Fluid Volumes (being preferably the aviation value of standard) from nozzle component 40.Therefore, user and/or system controller 150 can be closed with the corresponding a plurality of valves of needed quantity discharged selectively, in order to help its downstream line of emptying when valve 60 cuts out, this valve can have common outfall pipeline or with relevant opening (as being positioned at 60 on valve on one's body or near the downstream of valve 60), opening is opened when valve 60, and opening is closed when valve is opened.Equally, in order to help when outlet valve 68 cuts out fluid fillup valve 60 fluid downstream pipelines and open valve 60 after discharging, an available common blow off valve or pipeline are placed on the nozzle component 40, and when injecting fluid line, it is opened; When filling with, fluid line closes.

Though can adopt the valve of upstream of control nozzle component 40 to discharge a certain amount of beer, because the pressure by system changes and the pressure transmission time is fixing, it is lower to cause discharging precision, so this design is not preferred usually.Yet, pressure changes and the pressure transmission time is subjected to the type of the specific position of used valve 60 and H Exch 34 and size impact very greatly, therefore, by adopting H Exch that has the low pressure effect on the fluid food in system or the problem that valve 60 is placed on the control that can alleviate relevant this class valve between H Exch 34 and the nozzle component 40.

Should see, because the volume of beer of discharging from nozzle component 40 can adopt aforesaid flow gauge and timer-operated pressure sensor to measure when discharging, so with regard to available common mode, just can monitor from total volume of beer of any or all nozzle component discharge as system controller 150.In addition, this to consumption of monitoring beer, whether stealing and client's hobby and demand are arranged is useful especially.

Fig. 5 and 6 expressions refrigeration system of the present invention.Different with traditional sales stand, the present invention does not need keg storage area heat-insulating or refrigeration.Do not replace with the H Exch refrigeration system that describes below owing to do not need the refrigeration system of keg storage area, can save cost and maintenance cost greatly, obtain a more effective refrigeration system.The keg storage area of heat insulation and refrigeration is to being useful especially more than two days between the keg draining period.Yet as competitive sports with under the situation of the high capacity of the sales stand of the special permission celebrating a festival discharging, keg be opened the back rapidly discharging be enough to remove and prevent rotten and refrigeration that carry out.The refrigeration system of not shown cooling keg storage area if desired, can adopt refrigeration system in the sales stand 10 that illustrates in the drawings.This system and their operational circumstances are known those skilled in the art, therefore are not further described here.

At first referring to Fig. 5, it briefly shows refrigeration system 48 of the present invention, it illustrates four primary members of a refrigeration system: a compressor 82, condenser 84, expansion valve (being the capillary tub 86 of the winding supplied with of three parts in illustrated compression) and evaporator (in illustrated compression, be posture H Exch 34 or discharge rifle formula H Exch 44).In this refrigeration system 48, though can adopt a lot of different working fluids, preferably adopt working fluid R-22 as ammoniacal liquor, R-12 or 12-134a or 12-404a.

In the used vapor compression machine refrigerating cycle, compressor 82 receives lower pressure and hi-heat refrigerant gas, and these refrigerant gas are compressed to elevated pressures and hi-heat refrigerant gas in as the preferred embodiment of the present invention.This refrigerant gas is delivered to condenser 84 by gas line 88 and is cooled to the refrigerant liquid with elevated pressures and lower temperature.Though have multiple different condenser now, preferably a kind of common air cooled condenser of condenser 84, it has at least one fan blows air on the pipeline of condenser, with cooling refrigerant wherein.By behind the condenser 84, the capillary tub 86 of the winding that the refrigerating fluid of elevated pressures and low temperature is supplied with by three parts produces the refrigerating fluid of lower pressure and low temperature thus to reduce the pressure of refrigerant.This refrigerating fluid absorbs the heat from beer, cooled beer therein by H Exch 34,44 then.The refrigerant gas of higher temperature that is produced and low pressure is delivered to compressor 82 (by the valve of discussing below 96) to carry out next circulation then.H Exch 34,44 the most handy common openable joints 92 (with preferably common threaded flair joint) like this, can be changed rapidly and easily by the device of refrigeration system 48 refrigeration.Equally, the refrigeration lines of linking on the H Exch 34,44 is preferably connected by common openable threaded flair joint 94.Those skilled in the art as can be seen, this joint can have multiple multi-form.Concerning those skilled in the art, therefore this joint and all know in order to all members that connect refrigeration system 48 and all joints and the attaching parts of their pipeline is not further described here.

The pipeline of any connection refrigeration system 48 can be firm, but these pipelines are preferably flexible, thereby is easy to connect and safeguard.And preferably transparent, thereby can observe fluid behaviour and purity.Particularly running to and returning refrigerant supply and return

line

50,52,54 and 56 from discharging rifle 16, these pipelines should be flexible, thereby make the removable discharging rifle of user.These pipelines are known in refrigeration and air-conditioning technical, and for example the automotive air conditioning hose of available flexibility is linked H Exch 44 on remaining member of refrigeration system 48.

Refrigeration system 48 of the present invention can be used to control the temperature by the beer of discharging rifle 16 and nozzle component 40 dischargings.Very wish to control the amount of cooling water of H Exch 34,44 in the present invention.As known in this technology, in order suitably to discharge beer, the pressure of beer must remain in the scope that is rather narrow, and beer temperature is very big to this pressure influence.Though require in nozzle component 40, to make beer to keep cooling, preferably can be as described below, the temperature of beer is controlled by control refrigeration system 48.Come control flows to cross the temperature of the beer of this system by control, also can control preferably by the mobile pressure variation that causes of aforesaid outlet valve 68 and the pressure (this is a key factor of aforesaid measurement beer discharging) of the beer in the system by refrigeration system.For example, if before the beer discharging, mobile outlet valve 68 is to reduce beer pressure earlier, in nozzle component 40, require the beer pressure of lower balance, system controller 150 may command refrigeration systems (below will describe in detail) reduce the beer pressure on the nozzle component 40 thus to increase the cooling on the H Exch 34.In other embodiments of the invention of beer pressure and temperature in the control system of having described in the above, this control is of great use.

In order to control this refrigeration system, be preferably in and settle common evaporator pressure regulating control (EPR) valve 96 between H Exch 34,44 and the compressor 82, this EPR valve 96 is linked on the refrigerant return line 54,56 in normal way.EPR valve 96 is measured the refrigerant pressure of refrigerant return line in 54,56 (with H Exch 34,44), and restriction comes the liquid stream of automatic heat-exchanger 34,44 or further opens the liquid stream of automatic heat-exchanger 34,44.Each changes the pressure that the mode of all knowing with those skilled in the art changes the upstream of EPR valve 96.Especially by regulating this valve, can increase and reduce the pressure in the H Exch 34,44.Increase the refrigerant pressure in the H Exch 34,44, reduced the ability that absorbs the heat of beer in the automatic heat-exchanger 34,44, therefore, reduced the cooling performance of H Exch 34,44, increased the temperature of passing through beer therebetween simultaneously.On the contrary, increased refrigerant when increasing the refrigerant pressure in the H Exch 34,44 and absorbed the ability of beer heat in the automatic heat-exchanger 34,44, so increased the efficient of H Exch and reduced the temperature of passing through beer therebetween.The pressure of EPR valve 96 upstreams can be controlled to cause the refrigerant cools ability to change accurately by regulating EPR valve 96, therefore can accurately control the temperature of discharging beer, and allow refrigeration system 48 to be independent of the running of carrying capacity ground continuously.This refrigeration system with traditional fluid food escaper is different, and in the refrigeration system of traditional fluid food escaper, when the carrying capacity in this system tailed off, refrigeration system usually must circulation and disconnected.This EPR valve preferably is connected on the system controller 150 and by it automatically to be regulated in the ordinary way, certainly if desired, and also can be by user's manual regulation.For this reason, temperature sensor (not shown) preferably be contained in nozzle component 40, H Exch 34,44 or the keg 22 or they near, be used for determining the temperature of beer in the system and a little information are offered system controller 150, system controller 150 scalable EPR valves 96 are to change the temperature of beer then.

Another kind of scalable refrigeration system 48 also is shown in the schematic view of Fig. 5 controls the method for the cooling of H Exch 34,44.Specifically, a downstream line 98 is preferably linked the discharge end of compressor 82, and the other end is linked from capillary tub 86 to H Exch on 34,44 the refrigerant supply line 50,52.Downstream line 98 is equipped with common parallel regulator 100, and it measures the pressure of refrigerant in the refrigerant supply line 50,52.And keep downstream line to close or open a certain amount ofly making refrigerant be discharged to refrigerant supply line 50,52 from the heat of compressor 82.Downstream line 98 and parallel regulator 100 the most handy common joints are linked on compressor 82 and the refrigerant supply line 50,52.Do that warm refrigerant that compressor 82 discharges mixes with cold refrigerating fluid in the refrigerant supply line 50,52 and to its heating by parallel regulator, reduced the ability of the heat of beer in the refrigerant absorption H Exch 34,44 thus, raise by the temperature of the beer in the H Exch 34,44.With the amount of the refrigerant gas of the heat of refrigerant mixed in the refrigerant supply line 50,52 can be by the parallel regulator accuracy control, to change the cooling power of refrigerant, therefore accuracy control the temperature of the beer that gives off, allow simultaneously refrigeration system 48 continuously, be independent of the operation of carrying capacity ground.As mentioned above, this refrigeration system with traditional fluid food is different, and the carrying capacity of traditional refrigeration system in this system hour usually must circulation and disconnected.This parallel regulator 100 is preferably linked on the system controller 150 and by its automatically regulating in the ordinary way, but if desired, also can be by user's manual regulation.A temperature sensor (not shown) preferably is contained in nozzle component 40,46 for this reason, in H Exch 34,44 or the keg 22 or near it, to determine the temperature of beer in this system, and with this system for supplying information controller 150, system controller 150 is regulated parallel regulator 100 then, thereby changes the temperature of beer.

Should see, EPR valve 96 can have the multiple different form that those skilled in the art is known with parallel regulator, and each in them all can open and close corresponding pipeline effectively and spray in the cold refrigerant lines with the pressure of refrigerant in the change system or with the refrigerant of heat.The member of these coolant systems plays the effect of valve at least, preferably can as a regulating control come echo probe to refrigerant lines in the threshold value that arrives automatically open and close (automatically keep thus refrigeration system 48 can be enough to keep work on the ability of needed beer temperature).To see that although in the preferred embodiments of the present invention as shown in the figure, comprised 100, one those skilled in the art of EPR valve 96 and regulating control the operation of this system can be controlled by one or any amount of these devices.If any one of these devices or two are simple valve rather than regulating control, still might flow through the pressure of beer and/or the temperature of

H Exch

34,44 and because temperature and/or the pressure that system controller 150 responses are measured is controlled refrigeration system by crossing operating valve 96,100 by aforesaid measurement.

Referring to Fig. 6, can see the posture H Exch 34 of a preferred embodiment of the present invention in more detail, it is the plate heat exchanger in a common cover preferably, have at least one beer input port 102,104, one refrigerant input ports 106 of beer delivery port and a refrigerant delivery outlet 108.In illustrated compression, this posture H Exch is four plate heat exchanger that independently pass through the fluid passage of H Exch 34 that have that are used for four kinds of different beer.Therefore, graphic posture H Exch 34 has four beer delivery ports 104 that different beer input ports 102 is different with four; And having a refrigerant input port 106 and a refrigerant delivery outlet 108, they are used for making refrigerant to pass through all parts of posture H Exch 34.Those skilled in the art can be seen, this posture H Exch 34 can be divided into any amount of independent sector (beer flow passage), these parts are corresponding with the needed beer quantity that runs to discharging frame 12, if desired, can adopt more refrigerant input and output mouth 106,108.This posture H Exch 34 even each part that can be each posture H Exch 34 have special-purpose refrigerant input and output mouth 106,108.In addition, to each beer discharging frame 12, this discharging frame 12 can have the independent H Exch 34 of the special-purpose refrigerant input and output mouth 106,108 of band.Plate heat exchanger with a plurality of fluid passages is known those skilled in the art, therefore is not further described here.As mentioned above, diffuser 30 leads to each fluid input port from corresponding keg 22, and links on the keg with common joint in the ordinary way.Similarly, refrigerant supply line 50 and refrigerant return line 54 lead to refrigerant input and output mouth 106,108 respectively, and coupled with joint in the ordinary way.The delivery port 108 of each posture H Exch 34 preferably reaches out mouth mask 66.

A problem that may occur when adopting common plate heat exchanger to come comestible fluid dispensing is to have a front space in this H Exch usually, this front space is nonconforming, because this zone be difficult to be cleaned (they can not become wet or be immersed in the cooling fluid in some cases), can be produced the pressure control problem in system, also can protect bacterial growth even may cause that the beer in the system is rotten.Referring to Fig. 6 and 6a, this front space 110 is zones that H Exch inside is higher than beer outlet 104, and during normal system operation, it does not fill fluid.Fig. 6 and 6a be expression plate heat exchanger of the present invention in detail.Know as those skilled in the art, make fluid to be cooled and refrigerant keep separate by one or more plate in the H Exch, a side of every block of plate exposes or is immersed in the refrigerant, and the opposite side of every block of plate exposure or be immersed in the fluid to be cooled.For the problem that prevents that above-mentioned front space from causing, preferably establish a vent 113 at the top of posture H Exch 54.This vent 113 has connection for bbreather pipe 115, and it can start into opening and closing vent 113.Connection for bbreather pipe 115 can be any valve that can open and close vent, but the check valve that preferably only allows gas to discharge from posture H Exch 54.This posture H Exch 54 also is preferably in its top and has the sensor 117 that can survey fluid pressure, and this sensor 117 can be a kind of in the polytype, and these types include but are not limited to; In order to roughly the optical pickocff of Fluid Volume in the front space of surveying posture H Exch 54, the liquid sensor of response liquid immersion, response since liquid contacts with sensor or sensor on have the temperature sensor of the temperature difference that liquid produces, level sensor mechanical or electronic mechanical or the like.Being connected and operating in technical saying of vent 113, connection for bbreather pipe 115, sensor 117 and they is common.Although connection for bbreather pipe 115 can manual unlocking and is closed (also being in normal way), preferably by with 150 controls of sensor 117 bonded assembly system controlleies.Yet, should see that circuit can separately be powered and carry to connection for bbreather pipe 115 and sensor 117, this circuit receives the signal from sensor 117, with this signal control connection for bbreather pipe 115.Sort circuit is known those skilled in the art, therefore also falls in the spirit and scope of the present invention.

In operation, connection for bbreather pipe 115 is opened to allow fluid to discharge from posture H Exch 54.When having liquid to exist, the top that makes sensor 117 detect posture H Exch 54 (plays dynamic height or maximum fills height) at the fluid food of posture H Exch, sensor 117 preferably transmits one or more signals to system controller 150, controller sends one or more signals again to cut out connection for bbreather pipe 115, in case the fluid stopping body is discharged from posture H Exch 54.Sensor 117 is preferably selected and is positioned in and just closes outlet valve 115 when posture H Exch 54 just has been full of beer.According to the difference of used sensor 117 types, sensor 117 can be placed on vent 113 and survey beer and originally enter the situation of vent 113 even can be attached on the connection for bbreather pipe 115 or just be contained in its sidepiece.Owing to adopted above-mentioned ventilation design, system controller 150 gas in the space of the beer elevation-over of discharging posture H Exch 54 when wanting of in officely what is the need for, this not only can be avoided the problems referred to above relevant with front space, and can more easily clean.Specifically, when washing fluid sprayed into this system, connection for bbreather pipe 115 can be worked to guarantee that washing fluid contacts, washes and clean the All Ranges of posture H Exch 54 with sensor 117.

Those skilled in the art is all known, and much other ventilation assembly and member all can be used to substitute above-mentioned and graphic aeration vent 113, connection for bbreather pipe 115 and sensor 117.These other ventilation assembly and member all falls within the spirit and scope of the present invention.

As a kind of ventilation assembly of the problem that solves above-mentioned posture H Exch front space and the substitute of member, what shape and front space 110 couplings can be injected or fill in to this front space 110 crams the material (not shown).Though can adopt as a lot of materials such as epoxy resin, plastics and aluminium, cram material preferably to make by material easy to clean, as brass, corrosion-resistant steel, Qin's fluon or other food stage synthetic material, preferably can be full of all front space 110 simultaneously.

Referring to Fig. 4 and 6, another key character of the present invention is about keeping the beer temperature in the nozzle component 40.As mentioned above, posture H Exch 54 of the present invention has a plurality of extended beer outlets.Each nozzle component 40 have 112, one beer delivery ports 104 of an input port in normal way (preferably common joint) link on the input port 112.The food grade materials of the most handy high thermal conductivity as corrosion-resistant steel and so on of each delivery port 104 is made.Fluid holding chamber 80 in each input port 112 and the nozzle component 40 also the food grade materials of handy high thermal conductivity make.

Distance between the cover 66 of the body of posture H Exch 54 and spout assembly 40 is preferably short as much as possible, can place and move on to and shift out from nozzle component 40 space that provides enough for container again simultaneously.This distance is (in illustrated compression, beer delivery port 104 and nozzle component input port 112 determined fluid passage or fluid line between posture H Exch 54 and the nozzle component 40 in conjunction with length) less than about 12 inches (30.5cm), this distance is preferably less than 8 inches (20.3cm), but is preferably in 1 and 6 inch (between 2.5～15.2cm).Therefore nozzle component 40 is extensions of H Exch.

Distance between the cover 66 of posture H Exch 54 and nozzle component 40 is very important to feature of the present invention: it can make beer temperature in the nozzle component 40 be held in as much as possible temperature when discharging posture H Exch 54, and this function is preferably undertaken by the good heat conducting material of beer delivery port 104 and nozzle component input port 112.Particularly flow through nozzle component and when exhaust outlet 70 was discharged, beer did not have the enough time from the best consumption temperature by 54 controls of posture H Exch big variation to take place when beer.When not from nozzle component 40 discharging beer, be starved of beer is remained on the best consumption temperature.

The beer escaper of prior art can not make the beer in the jet pipe keep enough coolings in the uncertain time, can not keep the beer refrigeration with effective and inexpensive manner again.And in the present invention, the distance between the fluid holding chamber 80 of refrigeration member (as posture H Exch 54) and nozzle component 40 preferably shortens the fluid that becomes to make by fluid holding chamber 80 and is held in temperature when discharging the posture H Exch near the temperature of the beer in the posture H Exch 54 or by the advection heat circulation.Specifically, in posture H Exch 34 bodies or the beer of the beer delivery port 104 of posture H Exch 54 be the coldest during 40 discharge side 70 normally from the posture H Exch to nozzle component, because outlet valve 48 is far away from low-temperature receiver, so the beer of outlet valve is the warmest.Therefore exist the temperature difference or thermal drop between the beer on the terminal of beer in the body of posture H Exch 34 and nozzle component 40.By adopting the aforesaid cover 66 that makes the posture H Exch near nozzle component 40, from around and the interior cold beer of the beer delivery port 104 of posture H Exch 34 with to the streamed fluid holding chamber 80 that flows to.Because cold fluid has the tendency of sinking, the cold fluid that enters the fluid holding chamber moves on to the foot of fluid holding chamber 80, i.e. the warmest position of beer in the nozzle component 40 is so cold beer mixes with warm beer and cools off warm beer.Because warm beer has the tendency of rising, the warm beer in the fluid holding chamber 80 rises to the position near low-temperature receiver (posture H Exch 34) therein.This convection circulation could keep the beer in the nozzle component to cool off when only the distance between posture H Exch 34 and fluid holding chamber 80 is quite lacked as mentioned above effectively.Although can not produce aforesaid beer cooling, but the wall of the fluid holding chamber 80 in the beer delivery port of being recommended 104, nozzle component input port 112 and the nozzle component 40 adopts the material of high thermal conductivity to help to dispose from posture H Exch 34, down to beer delivery port 104 and nozzle component input port 112 and cold down to fluid holding chamber 80 again, therefore should be cold by convection current with conduct the downstream that is configured to posture H Exch 34.

As mentioned above with the design of graphic H Exch and spout assembly in, posture H Exch 34 can make the beer in the posture H Exch 34 and the temperature difference between the beer in the fluid holding chamber remain in 5 ° of the Fahrenheits.(in 2.5～15.2cm) scopes time, this temperature difference can remain within 2 Degrees Fahrenheits at most preferred 1～6 inch to the distance of nozzle component at H Exch.In the present invention, these temperature difference can keep for a long time.Although in the system of prior art, adopted the low-temperature receiver far away of colder temperature to cool off the beer in downstream.But this type systematic is to work under the mixing of following factors, and these factors comprise a large amount of and invalid degradation of energy.Beer over cooling and longshore current body path produce big thermal drop (member temperature in the system even drop to below freezing) in some cases; This just can not or be difficult to draw system temperature of the present invention and pressure control.

As the refill-unit of above-described fixing nozzle component as nozzle component 40, Fig. 7 and 8 illustrates a kind of small-sized nozzle component 46 that discharges rifle 16 forms.Except following description, discharging rifle 16 adopts essentially identical member and attaching partss, and carries out work under the principle identical with aforesaid posture H Exch 34 and nozzle component 40.

Discharging rifle 16 has rifle formula H Exch 44, links on this H Exch from the fluid line 42 of keg 22.As posture H Exch 34, this rifle formula H Exch 44 is a plate heat exchanger preferably, and it has a plurality of beer input ports 114 and a plurality of beer delivery port 116, and they are corresponding with the different beer that are fed to discharging rifle 16; Also have refrigerant input port 118 and delivery port 120.From keg 22 lead to discharging rifle 16 fluid line each all link on the beer input port 114, link respectively on refrigerant input port 118 and the refrigerant delivery outlet 120 to refrigerant supply line 52 and the refrigerant return line 56 of discharging between the rifle 16 and operate in refrigeration system 48.All are technical to being connected of rifle formula H Exch 44 all to be common, and the most handy common joint connects.

As posture H Exch 34, rifle formula H Exch 44 preferably has separated a plurality of fluid passage and along the refrigerant passage of the fluid passage of each beer operation.H Exch (referring to illustrated compression, plate heat exchanger) with a plurality of fluid loculuses that separate and path is known to those skilled in the art, therefore is not further described here.

This rifle formula H Exch 44 preferably has many mouthfuls of beer delivery valves accepting beer from each beer delivery port 116.This beer delivery port 120 is preferably made shape as shown in the figure, leads to beer delivery valve 122 from rifle formula H Exch 44, and each in them all connects (as with common joint, soldering or the like) in the ordinary way.In addition, beer delivery port 116 can be linked on the beer delivery valve 122 with quite short fluid line (not shown), and these pipelines are linked on beer delivery port 116 and the beer delivery valve 122 in the ordinary way.

This beer delivery valve 122 preferably can be opened to electronic control a beer delivery port 116 from rifle formula H Exch 44 to beer delivery valve 122.Concerning those skilled in the art, all know wide variety of different types of valves and can implement this function.In illustrated compression, this beer delivery valve 122 is 4 tunnel common inputs, the electromagnetic valve of the rotation of 1 tunnel output.This beer delivery valve 122 preferably is electrically connected on the control desk 124, and this control desk preferably is installed on the face of rifle formula H Exch 44.In addition, this beer delivery valve 122 can be electrically connected on the control setup 20 of sales stand 10 by the electric wire (not shown) of longshore current body and

refrigerant lines

42,52,56 operations.In illustrated compression, control desk 124 has the button that the user operates beer delivery valve 122 in normal way.

The nozzle component 46 of discharging rifle 16 is basic identical with the nozzle component 40 of above-mentioned discharging frame 12, and works in very identical mode.Preferably have a discharging extension 128 yet cover 126, this part stretches out from exhaust outlet 130.Therefore, the fluid egress point of being determined by the opening of nozzle component, discharge beer from nozzle component moves on to from exhaust outlet 130 1 segment distances.When outlet valve 132 shift to by actuator 134 and by exhaust outlet 130 with discharging during beer, the beer by exhaust outlet 130 flows to into discharging extension 128, enters downwards in the container that will pour into.The discharging extension is used for guiding beer to enter container, but is not member required in this invention.Yet adopt discharging extension 128 when going up at discharging rifle 16 (operating in the nozzle component 40 same modes as above-mentioned escaper), SP Start Pickup 136 and closure sensor 138 preferably are installed in the end of discharging extension 128 as shown in the figure when SP Start Pickup 136 and closure sensor 138.

As the electronic of outlet valve 132 or automatically controlled alternative, should see, can use the motion of manually controlling outlet valve 132 by the user if desired.For example, the user can mechanically open outlet valve 132 with control setup as the button on the discharging rifle 16 of manual manipulation.This outlet valve also can come bias voltage to cut out with the those skilled in the art well-known way by the fluid pressure of pressure fluid food in one or more springs, magnet or the outlet.By handling this manual control device, the user preferably moves outlet valve 132 its low pressure closed position in holding chamber 140, and after this, outlet valve 132 is opened, and discharges beer on its low pressure.As another example, outlet valve 132 can adopt aforesaid manual methods start by the user, and after this, how long what regularly actuator (type of discussing in the past) was controlled outlet valve 132 opens maintenance.Should see that also this same mode of discharging rifle 16 in the above-mentioned manual control device of outlet valve 132 starts being used to of also can discussing is just now used the outlet valve 68 of posture nozzle component 40.

In operation, the user catches discharging rifle 16 and it is moved on to the top of the container of waiting to pour into beer.If desired, the user preferably changes the type of waiting to discharge beer by the control desk 124 that operations platoon fires on 16.If changed the type of waiting to discharge beer, control desk 124 is preferably directly delivered to a signal beer outlet valve 122 (or from responding the control system of control desk 124), to open and the selected corresponding beer delivery port 116 of discharging beer.Discharge rifle 16 then by a kind of starting in the following method: the user handles the controller on the control setup 20 of control desk 124 or sales stand; Or preferably start in the mode of discharging posture nozzle component 40 discussed above by SP Start Pickup 136.The beer perfusion that fluid holding chamber 140 usefulness of this space-time are selected, almost meanwhile outlet valve 132 is preferably shifted to exhaust outlet 130, to reduce the pressure in the holding chamber as mentioned above.

Although be not preferred, this fluid holding chamber 140 can be equipped with and top such vent, valve and the sensor module of discussing with reference to posture H Exch 34 with the same manner operation of vent, valve and sensor module.These assemblies preferably are positioned at the top of fluid holding chamber 140, are used for the ventilation of empty fluid holding chamber, and allow to flow to into fluid holding chamber 140 from the fast speed beer of beer delivery valve 122.This assembly can manually be controlled, but preferably is electrically connected on delivery valve 116, control desk 124, control setup 20 or the system controller 150, thereby opens and close after the fluid holding chamber has been filled with or filled with substantially with beer delivery valve 122.

After the beer of requirement had entered container, valve 132 preferably moves to closed discharge side 130, and the beer delivery valve preferably moves to off position.Preferably close outflow valve 122 at first comes emptying fluid holding chamber 140 to allow time enough.At this moment, can open vent above-mentioned, valve and sensor module (not shown), to assist emptying fluid holding chamber 140.When valve 132 turns back to when cutting out exhaust outlet 130 by actuator 134, spout assembly 46 performs the preparation of next discharge cycle.

In the operation of aforesaid discharging rifle 16, fluid holding chamber 140 is empty between the discharging of twice beer, if not so, remains on the beer of discharging from beer outlet valve 122 when wherein beer will discharge with next time and mixes.If the same beer of discharging in next discharge cycle, this is unnecessary; If select different beer in next discharge cycle, this is nonconforming.Do not meet the requirements the aforesaid operations though do not resemble, but also have a kind of operation of operation rifle of replacement, it keeps the beer in the fluid holding chamber 140, after at every turn by the each discharging that keeps the beer delivery valve to open, open outlet valve 132 simultaneously, and then close outlet valve 132.Therefore the operation of this discharge chamber resembles the operation of the spout assembly of above-mentioned discharging posture nozzle component 40 very much.This beer delivery valve 122 preferably by system controller 150 controls, to stay open, continuously discharges same beer.If yet select another kind of beer by control desk 124 or sales stand control setup 20, before discharging next time, the beer of fluid holding chamber 140 is wanted emptying.This emptying work can be undertaken by system controller 150 by the control desk 124 of user's operation or the control setup on the sales stand 20, perhaps carry out automatically by system controller 150, all receive an indication in each operation,, open different beer delivery ports 116 with starting beer delivery valve 122.In emptying operating period, beer delivery valve 122 cuts out, and outlet valve 132 is opened then, is mainly used in waste beer is discharged from fluid holding chamber 140.Actuator 134 preferably turns back to off position with outlet valve 132 immediately then, and starting beer delivery valve 122 is opened delivery port 116 corresponding to the beer that will discharge.In addition, go out mouth mask 126 and can be provided with common vent and connection for bbreather pipe (not shown), they are preferably opened by system controller 150 controls, with the beer in the fluid holding chamber of draining before opening beer delivery valve 122.No matter be by opening outlet valve 132 or the connection for bbreather pipe of opening in the mouth mask 126 discharges, can both open beer delivery valve 122 when mainly opening outlet valve 132 or connection for bbreather pipe, come emptying fluid holding chamber 140 by the pressure of the green beer of selected discharging.

In the most preferred embodiment of this discharging rifle 16, shown in Fig. 7 and 8, beer delivery valve 122 is the downstream of H Exch and then.The beer waste that this design has reduced when holding chamber 140 is full of beer between twice discharging, caused owing to emptying discharging rifle 16 between twice discharging of dissimilar beer.Yet, can also (although not being preferred) beer delivery valve 122 be placed in another location between keg 22 and the nozzle component 46.For example, the valve of a plurality of input port, single delivery port can be used as the upstream that substitute is placed in rifle formula H Exch 44, preferably all 4 fluid lines 42 will be linked the input port of valve in the ordinary way, and valve itself is linked the beer input port of rifle formula H Exch 44 in the ordinary way.This valve can be controlled with the beer delivery valve 122 essentially identical modes of above-mentioned preferred discharging rifle embodiment.The advantage that this design provides is: rifle formula H Exch 44 only need have a beer path, because only allow a kind of beer to enter rifle formula H Exch 44 at one time, this just can obtain simpler, a cheap and easy cleaned rifle formula H Exch.Yet this design-calculated shortcoming is: discharging or this rifle formula H Exch 44 of emptying are comparatively difficult between the discharging of two kinds of different beer.When discharging can not emptying rifle formula H Exch 44 and the situation of nozzle component 46 under, beer wherein can or push away over-heat-exchanger 44 by pressurized air in the pneumatic joint on the rifle formula H Exch 44 or gas (as from jar 24 supplies) with beer by the beer of the new selection of pass through discharging rifle 16 of flowing and come emptying.Though a certain amount of beer has been wasted in each emptying really, the beer capacity of both additions is quite little in rifle formula H Exch 44 or the nozzle component 46.

The nozzle component 40 of the advantage that above-mentioned and the discharging rifle 16 of the graphic preferred embodiment of the present invention are provided and discharging frame 12 and H Exch 34 very identical.For example, the pressure drop of the beer before opening exhaust outlet 130 in the holding chamber 140 of nozzle component 46 is controlled under the situation of foaming and carbonate gas loss minimum, and flow velocity faster is provided.As another example, 46 pairs of rifle formulas of nozzle component H Exch 44 is contiguous, and therefore same convection circulation cooling performance when providing with above-mentioned discharging posture spout assembly makes the beer that arrives exhaust outlet 130 remain on the in check chilling temperature.Should see, discharging rifle 16 (with the nozzle component 40 of discharging frame 12 when comparing) comparatively intensive feature between the cover 126 of the body of rifle formula H Exch 44 and nozzle component 46, provide short distance, this distance is at 1～6 inch (between 2.5～15.2cm), preferably about 1～3 inch (between 2.5～7.6cm).Because distance is shorter, the maximum temperature difference between the beer on beer in fluid holding chamber 140 and the rifle formula H Exch 44 is less than Fahrenheit 10 degree, preferably less than Fahrenheit 5 degree.In the scantling of discharging rifle 16 hour, shorter H Exch can cause the littler temperature difference to the distance of nozzle component.The size of the nozzle component of discharging rifle 16 nozzle component 40 preferably basic and in the discharging frame is identical.Yet, if desired, when discharging rifle 16 discharges with rate of cooling and/or flowing velocity, can adopt less nozzle component and less H Exch.Should see that also the control of above-mentioned refrigeration system with reference to Fig. 5 discussion and operation can be used in the cooling down operation of rifle formula H Exch 44 equally.

The rifle formula H Exch 44 shown in Fig. 7 and 8 and the relative direction of nozzle component 46 do not require when enforcement is of the present invention.Design shown in the figure: rifle formula H Exch 44 is placed, is handgrip form 142 or the like at the sidepiece of rifle formula H Exch 44 along the sidepiece of nozzle component 46, only as a kind of with respect in a lot of different relative direction of jet pipe fine horse part 46 of rifle formula H Exch 44, those skilled in the art can be found out, can have much other relative directions, be an angle (as 90 °) as nozzle component 46 and position shown in Figure 7, will be discharged in the nozzle component 46 from the beer of beer outlet valve 122 by a bend pipe.The design of the discharging rifle of these and other all falls within the spirit and scope of the present invention.Except these by the advantage that provides of discharging rifle 16, the advantage of a no less important is that discharging rifle 16 is hand-held and small-sized.Though known discharging rifle has been used to discharge multiple fluid food in prior art, be very limited in a lot of their purposes of different occasions.A main restriction is due to the fact that: promptly the fluid food in the discharging gun barrel line of prior art warmed after a period of time between twice discharging.Can't cool off it before these food are discharged, the vendor can only throw away the fluid that warms or make great efforts to sell client with them.In brief, be unacceptable owing to fluid warming in the pipeline between twice discharging makes the discharging rifle of a lot of fluid foods, it is especially common as beer that can not to be placed on ice the fluid food of selling all the more so.Discharging rifle 16 of the present invention is by providing a cooling mechanism (rifle formula H Exch 44) to solve this problem on discharging rifle 16.Therefore, even fluid food has warmed on fluid line 42, same fluid can meet the requirements and the controollable chilling temperature under discharge the discharging rifle.Need under situation for a long time, preferably fluid line 42 be drawn in and be stored in the storage room of aforesaid refrigeration in twice discharging of convection cell food.Therefore, coming only restriction of comestible fluid dispensing with this discharging rifle 16 is the rate of deterioration of the fluid food in the tank (keg 22).

The discharging rifle that above-mentioned and graphic discharging rifle 16 is a multiple beer.Should see, this discharging rifle 16 also is applicable to and only discharges a kind of beer, especially beer discharging rifle 16 can have a beer input port 114, a fluid line 42 that leads to keg 22 is linked on the input port in normal way, therefore this discharging rifle 16 preferably has a beer delivery port 116 that directly leads to spout assembly 46, does not therefore just need to have beer delivery valve 122 and lead-in wire relative, that be used for above-mentioned discharging rifle 16.This discharging rifle 16 is operated in the mode identical with the H Exch 34 of discharging frame 12 and nozzle component 40 substantially, but a fluid line, a beer input port and a beer delivery port that has H Exch are only arranged.Yet this discharging rifle 16 preferably has a manual drain button (not shown) at least, is used for hand starting actuator 134 to open exhaust outlet 130.The discharging rifle of preferred illustrated embodiment can discharge any in four kinds of beer that are fed to wherein selectively.But according to above-described principle of the present invention, any amount of beer all is not fed to discharging rifle 16 discharging of control (certainly, needing the opening of varying number and dissimilar valves according to the beer quantity that is fed to discharging rifle 16).The member that the posture H Exch 34 of top reference discharging frame and nozzle component 40 are described and the replaceability embodiment of operation equally also can be used as the replaceability embodiment that discharges rifle 16.

On the contrary, above-described discharging frame 14 can make into to operate with a plurality of fluid inputs that are similar to discharging rifle 16, the design-calculated mode of single fluid output, particularly as mentioned above with graphic, be not exclusively used in the nozzle component 40 of each beer delivery port 104, this discharging frame 14 can have a beer delivery valve, and beer delivery port 104 is linked on this delivery valve in the mode that is similar to the beer delivery valve 122 that discharges rifle 16.Nozzle component 40 preferably is similar to the nozzle component 46 of discharging rifle 16 shown in Figure 7, and operates in the mode similar with it.But the control setup of this system preferably is positioned on the sales stand control setup rather than on posture H Exch 34.Top alternative embodiment with reference to member that discharges rifle 16 descriptions and operation can be used as the alternative embodiment of posture H Exch 34 and nozzle component 40 equally.

As mentioned above, a big problem of existing fluid food escaper is to be difficult to keep fluid escaper cleaning.A lot of fluid foods (comprising beer) are suitable for bacterium and other growth of microorganism especially.Therefore, on any time of emissions operation, all should carry out often and completely cleaning with any zone of fluid food fluid in contact escaper.But, even often clean up hill and dale and still can not prevent the rotten and pollution of fluid food, particularly inject the preferred embodiment of fluid food at dependence lower surface of the present invention, being starved of provides routinely a kind of or the method for the surface exposed to air of sterilizing frequently.Fig. 9 shows the device that carries out this function.This device relies on the sterilize surface of exhaust system of the present invention of ultraviolet light, and it comprises a ultraviolet light generator 144 of power supply in normal way, and this producer is linked on the zones of different of exhaust system.As an example, the ultraviolet light generator 144 of Fig. 9 is linked on the top of discharging nozzle component 40 of frame 12 and posture H Exch 34.

Therefore common ultraviolet disinfection device is restricted in their application owing to need big space.But, adopted common light transmitting fiber 146 that ultraviolet light is transferred to surface to be sterilized from ultraviolet light generator 144 in the present invention, this has just solved this problem.Those skilled in the art is all known ultraviolet light generator and light transmitting fiber and light transmitting fiber and can be linked on the light source light is passed to the locational method away from light source.Therefore, at least one light transmitting fiber 146 linked on the ultraviolet light generator 144 in normal way, and in the ordinary way stationary positioned on the surface of UV-irradiation or near it.In a preferred embodiment of the invention, two light transmitting fibers 146 from ultraviolet source 144 (it can be arranged in sales stand 10 or any other needed position) lead on the position of cover 66 sidepieces that discharge frame nozzle component 40.The terminal of this light transmitting fiber 146 is preferably linked on the configuration mirror 148, and this configuration mirror will be configured to from the ultraviolet light of light transmitting fiber 146 on the outside face of cover 66.Configuration mirror 148 and light transmitting fiber configuration are known those skilled in the art from the relation of fibre-optic light, therefore are not further described here.

Preferably having many light transmitting fibers 146 to lead to from ultraviolet light generator 144 is positioned in normal way and is fixed near the configuration mirror 148 of cover 66 outside faces, light transmitting fiber 146 and the quantity that is positioned near the configuration mirror 148 the cover 66 are determined by the quantity on the surface of needs sterilization, but preferably ultraviolet lighting can be mapped on the whole outer surface of cover 66.

Still as shown in Figure 9, a series of light transmitting fiber 146 preferably leads on the configuration mirror 148 that is installed in normal way in the container 58 that discharges rifle 16.Although light transmitting fiber is led on one's body 16 in the rifle of discharging, light transmitting fiber 146 preferably leads on the discharging rifle container 58.Configuration mirror 148 around nozzle component 40, the ultraviolet light that graphic configuration mirror 148 on the container 58 of discharging rifle 16 receives from light transmitting fiber 146, and send the ultraviolet light of reception.Like this light transmitting fiber 146 just with ultraviolet lighting the discharging rifle 16 (with the outside face that preferably goes out mouth mask 66) the surface on.

The sterilize surface of these positions, a plurality of other positions that light transmitting fiber can lead to exhaust system.As shown in Figure 9, light transmitting fiber can lead to the inside face of the inner front space of determining of sterilizing on the one or more configuration mirrors that are positioned on keg 22 tops.Light transmitting fiber also can lead on the discharging extension 128 and the locational configuration mirror around the exhaust outlet 70,130 that is installed in out mouth mask 126 and discharging rifle 16, thereby the inner of the mouth mask 66,126 of sterilizing out installs in the discharging extension 128 of discharging rifle 16 or its inside or the like of sterilizing, its end.What the present invention's (and prior art) exhaust system middle front part space formed all is that light transmitting fiber can lead to Anywhere, all can be with the UV-irradiation of sterilization on this front space surface.

Should see, although configuration mirror 148 will be configured to from the ultraviolet light of light transmitting fiber 146 on the surface to be sterilized, concerning implementing the present invention and do not require to have the configuration mirror.Ultraviolet light can directly be sent on the surface to be sterilized from light transmitting fiber 146.In this case, the face area that is exposed in the ultraviolet light is significantly smaller than the situation that adopts configuration mirror 148, but for being used to the quite little surface of sterilizing, can be satisfactory especially like this.In addition, light transmitting fiber 146 only is multiple a kind of in the different ultra violet light emitter of the present invention of can be used for.For example, if desired, light transmitting fiber 146 can be substituted by light pipe, and is known as those skilled in the art, and light pipe has the ability that receives light and outwards dispose light along its length at an easy rate.The mode that the figure of this light configuration is specially adapted to can not accomplish with light transmitting fiber is mapped to the ultraviolet lighting of sterilizing on a plurality of surfaces.For example, the light transmitting fiber 146 that leads to the cover 66,126 of nozzle component 40,46 can be replaced by common light pipe, and these light pipes surround nozzle component 40,46, or lead to the sidepiece of nozzle component 40,46.Light pipe can lead to any position that the front is described with reference to light transmitting fiber, if necessary, even sterilize their inside of the fluid line that can pass system.

The quantity and the position of light transmitting fiber 146 shown in Figure 9 and configuration mirror 148 are arbitrarily, only illustrate with exemplary forms among the figure.Those skilled in the art can see that any amount of light transmitting fiber, configuration mirror, light pipe or other ultraviolet light emission device all can be used on the position of the interior or outer any needs of fluid food tapping equipment.

In order to make cleaning of the present invention easier and thorough, the most handy grade metal of all members of this fluid system, as corrosion-resistant steel, brass manufacturing, just except sealing member, joint and the valve member, they are made by food grade plastic or other needed synthetic material.In preferred embodiment of the present invention, the outside face that goes out mouth mask 36,126 and discharging extension 128 has Qin's fluon (teflon) coating that helps cleaning.If desired, teflon, the surface as going out mouth mask 36,126 and discharging extension 126, surface of outlet valve 68,132 or the like are also coated in other surface that is beneficial to bacterium and other growth of microorganism in the device.

Description and illustrated embodiment are not construed as limiting notion of the present invention and principle only as example above.For this reason, those skilled in the art can be seen, under the situation that does not exceed the spirit and scope of the present invention of being set by claims, can make various changes to member, their configuration and layout.Describe for example and graphic each the preferred embodiments of the present invention have adopted

plate heat exchanger

34,44 to cool off fluid food by wherein, therefore plate heat exchanger is to recommend use in the present invention because its efficient is higher.But those skilled in the art can see that much the H Exch of other type can be used to replace preferred

plate heat exchanger

34,44, and they include but are not limited to shell-type and tubular heat exchanger, the pipe in tubular heat exchanger, heat pipe or the like.

In addition, describe above each and illustrated embodiment has the interior keg 22 of the one or more sales stand that is stored at refrigeration 10, but should see that the present invention does not rely on the refrigeration in fluid food source to discharge cold fluid food.Because the fluid food that enters

nozzle component

40,46 is by corresponding

heat exchanger

34,44 coolings, the temperature of the fluid food of H Exch 34, the 44 upstreams only desired work capacity of refrigeration system with the

H Exch

34,44 of the supply system cryogen is relevant, therefore, if desired, keg 22 can connect and at room temperature discharge from device of the present invention.Basically the present invention has adopted quite little and more efficiently method actv. H Exch quick cooling fluid food before discharging, replaces the extremely low common way of efficient of the fluid food cooling of the big volume of maintenance in the considerable time before discharging.
