BACKGROUND OF THE INVENTION
The present invention relates to a temperature and pressure adjusting device for a sparkling beverage supply apparatus for adjusting the pressure of a container storing a sparkling beverage such as draft beer according to the temperature of the beverage to be supplied.
[0002]
[Prior art]
When selling draft beer stored in a barrel, carbon dioxide gas is filled into the barrel, the draft beer is pushed out, cooled through a cooler, and distributed to a mug or the like. That is, as shown in FIG. 7, a dispenser head 142 is attached to an outlet 141 of a draft beer barrel 140 as a sparkling beverage container, and a gas pipe 145 of a carbon dioxide gas cylinder 144 as a gas supply source is connected to this, and an extraction pipe 146 is connected, and the high pressure carbon dioxide gas from the carbon dioxide gas cylinder 144 is supplied into the draft beer barrel 140 via the pressure reducing valve 147, and the draft beer in the draft beer barrel 140 is pushed out to the extraction pipe 146 by the pressure, and the draft beer in the extraction pipe 146 is It is cooled through a cooler 148 and extracted into a mug 150.
[0003]
When extracting draft beer, it is desirable to produce a predetermined amount of fine creamy foam, which greatly affects the flavor of the beer. The foaming state of beer is related to carbon dioxide pressure at the time of extraction, beverage temperature, extraction speed, and the like. The amount of carbon dioxide dissolved in the sparkling beverage such as draft beer is determined by the beverage temperature and the external pressure. That is, when the pressure of carbon dioxide gas acting on the beverage is constant, the higher the beverage temperature is, the easier it is to foam, and the faster the extraction speed is, the easier it is for the beverage to flow or stir. Therefore, it is necessary to add an appropriate carbon dioxide gas pressure corresponding to the beverage temperature in the draft beer barrel 140, and this gas pressure needs to be increased as the beverage temperature is higher. If the pressure is too low, the gas is released from the beverage. The carbon dioxide cannot be suppressed, and it becomes a so-called foolish beer. On the other hand, if the pressure is too high, the carbon dioxide gas dissolves in the beer, resulting in a pungent and stimulating taste, and the extraction speed is increased, resulting in an increase in bubbles during extraction. Thus, maintaining the carbon dioxide pressure applied to the draft beer barrel 140 at a predetermined value is important for managing the flavor and quality of the draft beer.
[0004]
Therefore, at the time of extracting beer, the pressure control valve 151 is manually adjusted by looking at the state of foam extracted, and the pressure of carbon dioxide gas supplied to the draft beer barrel 140 is adjusted. However, it is difficult to perform appropriate pressure adjustment, and this pressure adjustment requires years of experience and intuition.
[0005]
As a measure for adjusting the pressure of carbon dioxide gas supplied into the draft beer barrel, a device for adjusting the pressure of carbon dioxide gas supplied to the draft beer barrel according to the temperature of the beer has been developed. For example, as shown in FIG. The temperature sensing cylinder 179 is fixed to the draft beer barrel 140, and the flow control valve 152 such as a diaphragm valve is operated by changing the pressure of the sealed fluid in the temperature sensing cylinder 179 depending on the temperature, and the temperature of the draft beer barrel 140 is increased. Some are used so that the pressure of the supplied carbon dioxide gas increases. However, in such a pressure control valve 152, since the temperature sensing cylinder 179 which is the temperature sensing part is fixed to the side part of the draft beer barrel 140, the temperature is different from the temperature of the beer in the barrel. Even if the pressure is adjusted, appropriate adjustment cannot always be performed.
[0006]
For this reason, if the pressure is lower than the appropriate pressure, the carbon dioxide gas will be foamed, resulting in a beer that is unintentional. On the other hand, when the pressure is higher than the appropriate pressure, the beer that has flowed out has too much foam, making it difficult to handle when pouring into a mug, and the taste is also deteriorated. In addition, since the temperature sensing cylinder is used in the above technique, the gas enclosed in the cylinder may gradually leak, and in this case, not only the predetermined characteristics cannot be obtained but also the gas is leaking. There is also a problem that it is not possible to easily determine whether or not.
[0007]
Furthermore, the carbon dioxide gas pressure (equilibrium pressure) depending on the temperature of the draft beer is different for each brand as shown in FIG. 11, for example, and there is a problem that the appropriate pressure corresponding to the brand cannot be adjusted. That is, FIG. 11 shows the equilibrium pressures of the drafts of A draft and S draft beers manufactured by Company A and the draft of carbon dioxide, (a) is a table showing actual data, and (b) is the data. This is a plotted graph. From this, it can be seen that S draft beer is preferably about 10% higher in gas pressure than A draft beer, and that the temperature control requires strict management of several percent.
[0008]
As a method for adjusting the pressure of the carbon dioxide gas supplied to the draft beer barrel, a pressure adjusting device 155 as shown in FIG. 9 described in JP-A-7-76398 has been proposed. In this pressure adjusting device 155, a second opening 161 for supplying carbon dioxide to the draft beer barrel 140 through a first opening 158 that communicates with the carbon dioxide cylinder 144 and introduces carbon dioxide through a primary pressure regulating valve 157, draft draft beer barrel Each opening of the 4th opening 166 which supplies draft beer from 140 via the flow regulating valve 160 to the cock C via the cooler 164 is provided. The main body 167 of the pressure adjusting device 155 includes a partition wall 168, the internal chamber is divided into right and left, the left chamber is a carbon dioxide pressure adjusting chamber described later, and the third opening 163 and the fourth opening 166 are in the right chamber. The draft beer distribution room 170 is provided. The carbon dioxide pressure adjusting chamber is divided into two by a wall portion 171, and the left side is a primary pressure chamber 172 communicating with the first opening 158 and the right side is a secondary pressure chamber 174 communicating with the second opening 161. A shaft 175 that slides left and right in the drawing through the partition wall 168 is provided in the pressure adjusting device 155, and is always pressed to the left in the drawing by a heat sensitive spring 176 that increases in pressing force as the temperature increases. The shaft 175 is provided with a rod 177 penetrating the through hole 169 of the wall portion 171, and a cylindrical valve seat 180 protruding from the wall portion 171 is opened and closed by a valve seat 178 provided at the tip thereof.
[0009]
The pressure adjusting device 155 configured as described above, when opening the cock C and extracting draft beer to the mug 150, determines the temperature of the draft beer flowing from the third opening 163 to the fourth opening 166, and the heat sensitivity in the draft beer circulation chamber 170. Detected by direct contact with draft beer by a spring 176, and when the temperature is high, the shaft 175 is strongly pressed to the left in the figure, against the pressure of the carbon dioxide gas applied to the primary pressure chamber 172 and the secondary pressure chamber 174. The shaft 175 is moved to the left, the valve seat 178 is moved away from the tip of the valve seat 180, the opening area is increased, and the carbon dioxide gas pressure from the primary pressure chamber 172 to the secondary pressure chamber 174 is increased. The carbon dioxide pressure in the barrel 140 is increased. Moreover, when the temperature of draft beer is low, it acts contrary to the above, and the carbon dioxide pressure to draft beer barrel 140 is lowered. Therefore, the pressure adjusting device 155 adjusts the pressure of the carbon dioxide gas supplied into the draft beer barrel by directly detecting the temperature of the draft beer to be extracted, and automatically adjusts the pressure without depending on the intuition of the user. To be able to do that.
[0010]
In the prior art, a bubble breaker 149 is provided, and various types of bubble breakers are used. For example, a bubble breaker as shown in FIG. 10 has been proposed. That is, a float valve 184 is provided in a float chamber 183 in the case 182, and the float valve 184 is provided so as to be movable up and down around a guide rod 187 suspended from an operation cap 186 that covers the upper end of the case 182. The valve seat 189 is opened and closed by the valve portion 185 at the lower end of the float valve 184 in accordance with the liquid level of the beer. The beer extracted from the barrel passes through the annular passage 202 from the introduction hole 201 of the nozzle forming body 200 embedded in the main body 197, and floats from the spout 204 at the tip of the nozzle 203 erected from the annular passage 202. 183 is ejected into the interior. When liquid beer is ejected from the spout 204, the ejected liquid collides with the lower surface of the flange 205 provided on the float valve 184, and the force prevents the float valve 184 from being drawn into the flow. Supply from the outlet 206 to the third opening 163. When bubbles increase in the beer supplied from the beer barrel 140, the flow is lowered and the valve seat 189 is closed by the valve portion 185. In this apparatus, a guide 207 extending horizontally is provided at the tip of the spout so that beer from the spout 204 of the nozzle 203 is reliably guided to the flange 205 of the float valve 184.
[0011]
[Problems to be solved by the invention]
In the pressure adjusting device for appropriately maintaining the carbon dioxide pressure supplied to the draft beer barrel according to the temperature of the beer, the technique as shown in FIG. 9 disclosed in Japanese Patent Laid-Open No. 7-76398 as described above is supplied. Among the various prior arts, the detection of the temperature of beer can be said to be reliable and most preferable in that it directly senses the temperature of the beer and adjusts the carbon dioxide gas pressure. Beer directly touches a coiled spring as a heat-sensitive body, so beer crystals tend to accumulate in this coil-shaped heat-sensitive spring, and there is a drawback that it must be cleaned frequently, and it is installed in the flow path of beer. In addition, there is a drawback that a strong turbulent flow is formed by passing the coil spring-like member and bubbles are easily generated from the liquid. Further, in the technology disclosed in the above publication, there is no means for finely adjusting the pressure adjustment after the manufacture of the pressure adjusting device, and an appropriate gas corresponding to the brand as shown in FIG. 11 as described above. The pressure cannot be set. Furthermore, the beer supply device including such a pressure control device is obliged to be cleaned every predetermined period. However, when the pressure control device as described above is disassembled and assembled after cleaning at the time of cleaning, the setting is made. Therefore, it is not a practical device to have a means for adjusting this.
[0012]
Further, in the valve for adjusting the pressure, since the set pressure is widely adjusted by a spring, it is conceivable to apply a screw member for adjusting the bias force of the spring to the above-described technique. In such a case, if a screw detent mechanism is not provided, the screw will gradually loosen due to the force of the spring when shipped from the factory and after a long period of use, and the set pressure will change, maintaining the appropriate pressure. Therefore, it is necessary to appropriately arrange the adjusting means for that purpose.
[0013]
Furthermore, when pressure regulation is not performed appropriately as described above, there is a problem that the foam circuit breaker conventionally provided downstream of the temperature pressure regulation device does not function sufficiently in the draft beer supply line. That is, when the gas pressure of carbon dioxide gas supplied to the barrel is lower than the appropriate gas pressure, carbon dioxide gas foams and accumulates in the upper part of the foam circuit breaker, and the float falls to interrupt the supply of beer. is there. Conversely, when the gas pressure is too high, high-pressure gas accumulates in the upper part of the foam circuit breaker cover, and the float is sucked to the beer outlet instantly by the suction force when the beer is extracted. May be interrupted.
[0014]
Furthermore, in the conventional technology, a temperature and pressure adjusting device that supplies carbon dioxide gas at an appropriate pressure according to the temperature of draft beer into the barrel, and that the foam blows out together with the high-pressure carbon dioxide gas when the barrel is empty. Since the foam circuit breaker for preventing it is configured separately, there are disadvantages that the cost is increased and that maintenance is troublesome. These problems are not limited to the supply of draft beer but are also common problems when supplying sparkling beverages.
[0015]
Therefore, the present invention can directly detect the temperature of sparkling beverages such as draft beer extracted from the barrel and supply carbon dioxide gas of optimum pressure into the barrel, and the pressure is the brand of sparkling beverages such as draft beer. The temperature and pressure adjusting device for a sparkling beverage supply device that can be finely adjusted according to various conditions and that the setting does not deviate even when used for a long period of time and the internal washing operation is easy The purpose is to provide.

[0025]
A retainer 39 is fixed to the third spring pedestal 33, and holds a third spring 35 whose tips are separated from the first spring pedestal 31 and the fourth spring pedestal 28 in the illustrated state. The body 5 is formed with a clearance hole 25 that allows the internal working chamber 26 and the outside to communicate with each other, and the sliding rod 18 advances and retreats into the working chamber 26 due to a temperature change of the temperature sensing portion, and the second portion with respect to the diaphragm 32. The urging force of one spring 34 is adjusted so that the diaphragm 32 moves smoothly in balance with the pressure in the pressure chamber 36.
[0026]
The valve case 38 is fixed to the main body 5 when the male screw portion 40 of the valve case 38 is screwed into the female screw portion 37 formed at the rear end portion of the main body 5. As shown in the enlarged view of the valve open state in FIG. 3, the valve case 38 communicates with a gas inlet 41 communicating with a carbon dioxide gas cylinder and a barrel of draft beer disposed opposite to the gas inlet 41. A gas outlet 42 is provided. A valve chamber 43 is formed between the gas inlet 41 and the gas outlet 42, and a valve mechanism 44 is provided in the valve chamber 43.
[0027]
The valve mechanism 44 includes a valve seat 45 that is screwed into the opening of the valve chamber 43, and a valve body that includes a rod portion 47 that extends through the central hole 46 of the valve seat 45 with a gas flow gap. 48 and a return spring 50 that urges the valve body 48 in a direction to close the valve seat 53 of the valve seat body 45. The valve body 48 is provided with an O-ring 51 that closes the valve seat 53, and the tip of the rod portion 47 abuts the central recess 59 of the retainer 39 that holds the diaphragm 32 together with the third spring base 33. Yes. As a result, the urging force of the first spring 34 is adjusted according to the detected temperature of the temperature sensing member 15 as described above, and the force acts on the valve body 48 via the retainer 39. , The opening area of the valve seat 53 is adjusted, and the pressure of the carbon dioxide gas supplied into the barrel of draft beer is adjusted according to the temperature.
[0028]
On the other hand, as the foam circuit breaker to which the temperature / pressure adjusting apparatus according to the present invention is attached, a conventionally used foam circuit breaker can be used. For example, a foam circuit breaker as shown in FIG. 4 can be used. That is, in the foam circuit breaker of FIG. 4, the float chamber container 55 is screwed and fixed to the upper portion of the body 3, and the inner cylinder 56 protruding from the upper surface of the body 3 is disposed inside the float chamber container 55. The gas-liquid separation plate 58 is inserted into the inner surface of the float chamber container 55 through the upper end 57 of the inner cylinder 56 and a gap. In the upper part of the float chamber 60 inside the float chamber container 55, a fixing member 61 is inserted into the float chamber container 55, and the fixing member 61 fixes four guide rods 62 as a guide mechanism. This guide rod 62 penetrates the guide hole 65 of the flange portion 64 of the float valve 63, and thereby the float valve 63 floats on the liquid beer introduced into the inside and guides it to move up and down stably. ing.
[0029]
As described above, the beer inflow path 14 of the foam circuit breaker 2 from which the temperature sensing part 13 of the temperature pressure adjusting device 4 protrudes is formed with an inlet side opening 91 on the lower side and a float chamber inlet 92 on the upper side. A staying chamber 54 in which beer flowing through the hot part 13 protrudes is formed in the vicinity where the warming part 13 protrudes. As a result, when the supply of beer is temporarily stopped, the temperature of the beer in the inflow channel 14 can be prevented from changing rapidly, and inappropriate operation in the transient state of the temperature-pressure control device can be prevented. To be able to.
[0030]
Further, the entrance-side opening 91 in the inflow channel 14 has a smaller opening area than the exit-side opening 93 of the bubble circuit breaker 2, and the feeling of being provided in the vicinity of the entrance-side opening 91. The temperature of the temperature sensitive member is improved by causing the beer to collide with the warm portion 13 at a high speed.
[0031]
In operation of the temperature and pressure adjusting device for a sparkling beverage supply apparatus configured as described above, when beer from the draft beer barrel enters the inflow path 14 from the inlet side opening 91 of the foam breaker 2, a sense of protrusion is provided. It collides at high speed with the temperature sensing part 13 of the temperature member 15, and the temperature sensing member 15 directly detects the temperature of beer. When the temperature of the supplied beer is high, the temperature sensing member 15 expands, the sliding rod 18 is moved to the right in the figure, and the second spring pedestal 17 is pressed at the tip thereof to move to the right in the figure. The second spring base 17 presses the first spring base 31 via the second spring 30 having a relatively large spring constant. Thereby, the 1st spring base 31 cooperates with the sliding rod 18 which slides with the temperature-sensitive member 15 which protrudes in the supply path | route of a sparkling beverage.
[0032]
Further, the first spring 34 is compressed with the movement of the first spring base 31, and the set load of the first spring 34 increases. This load acts on the rod portion 47 of the valve body 48 via the third spring pedestal 33 and the retainer 39, and moves the valve body 48 to the right in the figure against the return spring 50. As shown, the O-ring 51 is spaced away from the valve seat and gradually opens the valve seat 53. In accordance with the degree of opening of the valve seat 53, the gas from the carbon dioxide gas cylinder flows into the pressure chamber 36 through the periphery of the rod portion 47 and the flow gap of the central hole 46 of the valve seat body 45, and from the gas outlet 42, A higher carbon dioxide pressure is applied to the barrel. In addition, when the temperature of the beer passing through the beer inflow path 14 is low, the operation is reversed to the above operation, the spring force of 34 and 35 is weakened, and the pressure of the carbon dioxide gas supplied into the draft beer barrel is reduced. In this way, the temperature of the draft beer supplied can be detected directly and with good sensitivity, and the pressure of the carbon dioxide gas supplied into the barrel can be optimally controlled.
[0033]
In the initial setting of the temperature-pressure adjusting device 4, for example, as shown in FIG. 11, in order to match the optimum temperature-pressure characteristics that differ depending on the brand of draft beer to be supplied, the fine adjustment shown in FIG. The screw 20 is rotated to adjust the contact position between the temperature sensing portion 13 and the taper portion 24, and the entire temperature sensing body 12 is moved. Thereby, in relation to the movement of the sliding rod 18 by the temperature sensitive member 15, the position of the first spring pedestal 31 is adjusted, and the set load of the first spring 34 is adjusted to adjust the above characteristics. be able to.
[0034]
At this time, the second spring pedestal 17 that is directly moved by the sliding rod 18 and the first spring pedestal 31 are provided with a second spring 30 having a strong spring force by the first spring 34, so that the first spring It is possible to prevent an excessive bias from being applied to 34. Further, by providing the third spring 35 fixed to the third pedestal 33, characteristics other than the characteristics of the first spring can be imparted, and an arbitrary non-linear characteristic can be obtained.
[0035]
Moreover, since the temperature sensing part 13 of a comparatively simple shape is arrange | positioned in the beer inflow path 14, the part which beer accumulates compared with what arrange | positioned the coil spring as a temperature sensing body in the said conventional beer inflow path. , The hygienic device can be obtained, and the generation of bubbles can be prevented. Further, since the thermosensitive member is encapsulated with thermowax or the like, the characteristic change due to gas leakage does not occur unlike the case where the thermosensitive gas is encapsulated in the thermosensitive cylinder, and the thermosensitive member can be used for a long period of time. Moreover, since the said temperature / pressure control apparatus 4 is integrated with the bubble circuit breaker 2, the maintenance becomes easy and it can be set as an inexpensive apparatus.
[0036]
Another embodiment of the temperature / pressure adjusting device 4 will be described with reference to FIG. In this embodiment, the main body 100 of the temperature / pressure adjusting device 4 is formed in a substantially inverted T shape, and in the working chamber 101 extending in the horizontal direction, a cam surface is formed on the outer periphery, and the temperature sensing element 12 is formed in the center. A cam member 103 in which the cylindrical portion 16 is loosely fitted, a cap 104 screwed into the rear end portion of the main body, a spring 106 contracted between the inner surface of the cap and the rear end portion 105 of the cam member 103, and a cam member The adjusting screw 107 is screwed into the rear end portion 103 of the main body 103 and the tip abuts against the tip of the sliding rod 18 in the cylindrical portion 16, and the loosening prevention spring 108 of the adjusting screw 107 is provided.
[0037]
On the outer periphery of the cam member 103, a tapered cam surface 110 and an excessive load preventing surface 111 having a flat height are formed continuously with the highest tapered portion. A protruding portion 112 is formed on a part of the outer periphery of the rear end portion 105 of the cam member 103, and this protruding portion 112 is fitted into a guide groove 113 extending in the axial direction formed on the inner surface of the working chamber 101 of the main body 100. Therefore, the cam member 103 is prevented from rotating during fine adjustment so that it can be easily finely adjusted.
[0038]
An operating mechanism is arranged in the vertical direction of the substantially inverted T-shaped temperature / pressure adjusting device 4 in the drawing, and a valve device 115 is screwed and fixed to a valve holding portion 114 protruding from the main body 100. The diaphragm 116 is clamped and fixed between the stepped portions of the valve holding portion 114 at the time, and the diaphragm 116 is held between the retainer 117 and the receiving plate 118. The tip of the protrusion 121 of the spring pedestal 120 abuts on the cam surface of the cam member 103, and a spring 122 is contracted between the upper surface of the spring pedestal 120 in the drawing and the receiving plate 118. The configuration of the valve device 115 is exactly the same as that of the previous embodiment shown in FIG. 1 and operates in the same manner, so that the description thereof is omitted. Further, since the bubble circuit breaker 2 to which the temperature / pressure adjusting device 4 is fixed is exactly the same as that of the embodiment shown in FIG.
[0039]
In the operation of the temperature / pressure control apparatus 4 configured as described above, the temperature of the beer in the beer inflow path 14 of the foam breaker 2 rises, and the temperature sensing unit 13 protruding into the beer inflow path 14. When the inner temperature sensing member 15 expands, the sliding rod 18 moves to the right in the drawing, pushes the adjustment screw 107, and moves the cam member 103 fixed to the adjustment screw 107 to the right against the spring 106. Moving. As a result, the spring pedestal 120 moves upward, and the set load of the spring 122 is increased. Thereafter, as in the above embodiment, the valve body 48 is moved upward in the figure and the valve seat 53 is opened, so that the carbon dioxide gas from the gas inlet 102 indicated by the broken line in the figure is transferred from the valve chamber 43 to the pressure chamber 36. The carbon dioxide gas of a predetermined pressure is made to act in the barrel of beer from a gas outlet (not shown).
