Description

TECHNICAL FIELD [0001] The present invention relates to a slush beer foam manufacturing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for manufacturing slush beer bubbles and a method for manufacturing the same.

Generally, a draft beer refers to a beer that has been filtered out of yeast using a filter, without fermenting the fermented beer after aging and then sterilization. It is important to keep the temperature of the draft beer cold at all times. Accordingly, at a business office or the like, beer stored in a beer tank is transported by carbonic acid gas, and the beer is passed through a cooler before being finally discharged through a beer cock, thereby providing a cold beer.

When the draft beer is taken out of the beer coke, the beer and the froth are placed on the beer. The bubbles block direct contact between the beer and the atmosphere and prevent the release of carbon dioxide from the beer into the atmosphere, thus maintaining the cooling sensation and flavor of the beer for a long time.

In recent years, techniques for providing the draft beer and foam in the form of a slush have been developed.

However, in the conventional case, there is a problem that the particles of the slush-form foam produced are too large and coarse and inconvenient to drink.

Also, in the process of manufacturing a beer in the form of a slush, the carbonic acid of the foam is blown, so that the taste of the foam is softer, and when the beer is melted, the beer is sour.

In addition, the bubbles produced in the form of slush are too hard to separate the beer from the slush foam, which is inconvenient for the user to drink beer.

Provided is a slush beer bubble manufacturing apparatus and a manufacturing method for manufacturing slushy foam particles smaller and softer.

The present invention also provides a slush beer bubble manufacturing apparatus and a manufacturing method thereof, which can maintain the shape of the slush beer bubble for a long time on a beer.

The present invention also provides a slush beer foam manufacturing apparatus and a manufacturing method, which can sufficiently inject carbon dioxide into a slushy foam.

The present invention also provides a slushy beer foam manufacturing apparatus and a manufacturing method thereof, which can enhance and diversify the taste of beer foam.

The manufacturing apparatus of this embodiment comprises a container in which a beer or foam is received, a cooling section which is disposed in the container and cools the beer or foam contained in the container with a foam in a slush state, A discharge portion for discharging the slush foam, and a carbonic acid supply portion connected to the inside of the container to inject carbon dioxide into the slushy foam.

The manufacturing apparatus may be a structure for further supplying the additive into the container.

The additive may be at least one stock solution or syrup of fruit, coffee or sugar including lemon or grapefruit.

The container may be configured such that an upper end thereof is opened to form an inlet for introducing beer or foam, a lid is provided to be openable at an open top, and a valve for selectively discharging the gas inside the container is installed at an upper end of the lid.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

1 and 2 show a slush foam beer manufacturing apparatus according to the present embodiment.

The manufacturing apparatus 100 according to the present embodiment includes a container 10 in which beer or foam is received and a beer or foam disposed in the container 10 and accommodated in the container 10 in a slush state A discharge part 50 installed at the outlet 16 of the container 10 for discharging the slush foam inside the container 10 and a discharge part 50 connected to the inside of the container 10 to discharge the slush foam, And a carbonic acid supply unit 70 for injecting carbon dioxide gas into the foam.

Through the above-described structure, the apparatus can produce a soft slush state beer foam into which carbon dioxide gas is injected, and provide it on the beer.

The container 10 forms a storage space therein, and the upper end thereof is opened to form an inlet 14 into which beer or foam is introduced. The beer or foam is fed into the container 10 through the open top of the container 10. Here, beer refers to beer solution excluding bubbles, bubbles means that beer solution swells the gas into hollow droplets, and slush refers to a mixture of solid ice particles and a liquid solution State. A slush bubble means a bubble in a slush state.

A lid (12) is provided on the opened upper end of the container (10) so as to be openable and closable. The lid 12 can be installed, for example, on a hinge shaft on one side of the top of the container 10 so as to be rotatable. Between the lid 12 and the container 10, a coupling hole 18 for fixing the lid 12 to the container 10 may be further provided.

The cover 12 blocks the container 10 from the outside and prevents foreign matter from entering the inside of the container 10. The inside of the container 10 is a region in which a substantially slush-like foam is produced, and it is possible to manufacture the slush foam even without maintaining the sealed state with the outside. In this case, the lid 12 can only serve to open and close the opened upper end of the container 10.

When the container 10 is hermetically sealed off from the outside, the quality of the slush foam to be manufactured can be further improved. To this end, the apparatus may further include a sealing pad 20 between the top of the container 10 and the lid 12 for sealing. The gap between the container 10 and the lid 12 is sealed by the sealing pad 20, and the container 10 is sealed. Accordingly, the pressure inside the vessel 10 is increased, and the carbonic acid gas content dissolved in the slush foam can be increased.

A valve 22 for selectively discharging the gas inside the container 10 is provided at the upper end of the lid 12 so that the internal pressure of the container 10 can be appropriately adjusted by discharging the internal gas when necessary.

In the present embodiment, the manufacturing apparatus is structured such that beer and foam are separately supplied into the container 10 and supplied. Beer and bubbles can be easily obtained, for example, from beer coke, which is commonly used to extract draft beer. The beer coke used to finally discharge the beer from the beer tank containing the raw draft beer is capable of separating and releasing the bubble together with the beer. A lot of techniques are already known about the structure of beer coke, and various products are available, so the detailed description is omitted here. Accordingly, beer and bubbles can be obtained by separating the beer and foam through the beer coke, and the foam and the beer can be separately supplied to the container 10.

Thus, the apparatus can separate the beer and the foam and feed them into the container 10, so that the particles of the slush foam can be formed to have a smaller, smooth and appropriate viscosity. This operation will be described in detail later.

In addition, the apparatus can further add additives that add flavor and aroma with the beer when the beer is poured into the container 10. The additive may be, for example, a lot of fruit juice including sugar such as lemon or grapefruit, syrup, coffee stock solution, sugar syrup, aspartame solution and the like.

By introducing the additive into the container 10, the desired flavor can be imparted to the slush foam, and the concentration and viscosity of the slush foam can be enhanced.

The cooling unit includes a cooling cylinder 30 installed inside the vessel 10 to cool beer or foam, a cooling jacket 32 installed inside the cooling cylinder 30 to exchange heat with the cooling cylinder 30, A screw blade 34 provided in a spiral shape on the outer circumferential surface of the cooling cylinder 30 to scrape the outer circumferential surface of the cooling cylinder 30 and a heat exchanging part 40 for circulating the refrigerant to the cooling cylinder 30 And a rotating part for rotating the screw blade 34 with respect to the screw shaft 34.

The cooling cylinder 30 is formed in a cylindrical shape, and beer and foam come into contact with the outer circumferential surface of the cooling cylinder 30 to be cooled. The cooling cylinder 30 may be made of stainless steel.

2, a housing 36 is provided at a lower end of the container 10 to support the container 10, a heat exchange unit 40 for driving the cooling unit in the inner portion of the housing 36, Respectively.

The heat exchanging unit 40 may be a structure using, for example, the heat of vaporization of a refrigerant such as Freon. The heat exchange unit 40 may include a circulation line 48 connected to the compressor 42 and the condenser 44, the expansion valve 46 and the cooling jacket 32 to circulate the refrigerant. The compressor 42 compresses the refrigerant to a predetermined pressure and then circulates the refrigerant. The condenser 44 condenses the refrigerant compressed by the compressor 42 and discharges heat to the outside through the blowing fan. The expansion valve 46 expands the refrigerant delivered from the condenser 44 and supplies it to a cooling jacket 32 serving as an evaporator.

The cooling jacket 32 is installed on the inner circumferential surface of the cooling cylinder 30 and evaporates and circulates the refrigerant passing through the expansion valve 46 to cool the cooling cylinder 30. The cooling jacket 32 may be closely attached to the inner circumferential surface of the cooling cylinder 30 and may be provided in a spiral shape along the axial direction. Since the cooling jacket 32 and the heat exchanging unit 40 are disclosed in many techniques using refrigerant, a detailed description thereof will be omitted.

As the cooling cylinder 30 is cooled, the slush particles condense on the outer circumferential surface. The slush particles that have settled in the cooling cylinder (30) are separated from the cooling cylinder (30) by the screw blade (34).

The screw blade 34 has a spiral shape extending along the outer circumferential surface of the cooling cylinder 30 and has an inner front end contacting the outer circumferential surface of the cooling cylinder 30 along the width direction.

The rotation axis 35 of the screw blade 34 coincides with the center axis of the cooling cylinder 30. [ The rotary shaft 35 of the screw blade 34 is disposed along the center of the cooling cylinder 30 and extends outwardly through the cooling cylinder 30. [ One end of the screw blade 34 extends toward the rotation center of the screw blade 34 and is connected to the rotation shaft 35.

The rotary unit includes a driving motor 37 installed inside the housing 36 and a driving motor 37 connected between the rotary shaft 35 of the screw blade 34 and the driving motor 37 to rotate the screw blade 34. [ The power transmission mechanism may include a power transmission mechanism. As the power transmission mechanism, for example, various structures such as a reduction gear group, a reduction pulley and a belt may be applied.

Accordingly, when the drive motor 37 is operated, power is transmitted to the rotation shaft 35 through the power transmission mechanism, and the rotation shaft 35 is rotated. Therefore, the screw blade 34 provided on the rotating shaft 35 rotates with respect to the stopped cooling cylinder 30. As described above, the screw blade 34 passes the outer circumferential surface of the cooling cylinder 30, and scatters the agglomerated slush particles on the surface of the cooling cylinder 30. The screw blade 34 has a spiral shape so that as the screw blade 34 rotates, the slush foam moves toward the outlet 16 of the vessel 10.

The bubbles and beer fed into the vessel 10 are made of slush foam while contacting the cooling cylinder 30. The produced slush foam moves toward the outlet of the vessel 10 in accordance with the rotation of the screw blade 34 and finally the carbon dioxide gas ejected from the carbonic acid supply part 70 is injected and discharged through the discharge part 50.

The carbonic acid supply unit 70 includes a storage tank 72 for supplying carbonic acid gas, a transfer pipe 74 connected to the storage tank 72 for transferring carbonic acid gas, a transfer pipe 74 connected to the transfer pipe 74, Closing valve 78 for opening and closing the transfer pipe 74 provided in the transfer pipe 74 and a control valve 78 for controlling the opening and closing valve 78, And a control unit (80) for selectively supplying carbon dioxide gas to the beer or foam in the state.

The control unit 80 controls the on / off valve 78 to supply carbon dioxide gas into the container 10 according to a predetermined time or at the time of discharging the slush beer.

In addition, the controller 80 controls the heat exchanger 40 to produce a slush foam, thereby controlling the cooling temperature of the interior of the container 10 by the cooling cylinder 30 to an appropriate level. To this end, a thermometer 82 for detecting the temperature is installed in the cooling cylinder 30 and connected to the controller 80. The controller 80 controls the heat exchanger 40 to adjust the internal temperature of the container 10 to the set temperature according to the detected value of the thermometer.

The carbonic acid gas is sprayed on the slush foam located on the side of the inner outlet 16 of the vessel 10 through the nozzle 76 provided on the transfer pipe 74. The carbon dioxide gas ejected by the slush foam is injected into the slush foam and melts into the foam. In addition, the carbon dioxide gas is sprayed on the slushing foam, which impacts the foam to form a small, soft creamy foam.

Thus, the slush foam is discharged to the outside through the discharge portion 50 in a soft state in which carbon dioxide is dissolved. A slushy foam with enough carbon dioxide does not disturb the taste and flavor of beer when topped on beer, and prevents the beer from becoming softer when mixed with beer.

In this embodiment, the spray position of the carbonic acid gas, that is, the mounting position of the nozzle 76 may be approximately the front face of the outlet 16 side or the outlet 16 side of the container 10. The bubbles and beer injected into the container 10 are made of slush foam and move along the screw blade 34 toward the outlet 16. By spraying the carbonic acid gas from the outlet 16, the carbonic acid gas is injected into the slush foam immediately before being discharged from the vessel 10, so that the slush foam can sufficiently absorb the carbonic acid gas.

Fig. 3 shows a cross section of the nozzle 76. Fig. 3, the nozzle 76 includes a funnel-shaped air outlet 83 having an inner diameter expanded toward the front end thereof, and a cone-shaped blocking member 85 movably fitted in the air outlet opening and closing the air outlet, And the blocking member is urged by an elastic spring 87 inside and is brought into close contact with the jet port 83 or is separated from the jet port by a carbonic acid gas pressure to open and close the jet port.

Thus, the carbonic acid gas is sprayed to the outside through the gap between the jetting port 83 and the blocking member 85 while spreading to the outside. Therefore, carbon dioxide gas is injected over a wider area, and carbon dioxide gas can be evenly injected into the slush foam.

Hereinafter, the process of manufacturing the slush beer foam from the present manufacturing apparatus will be described with reference to FIG.

The manufacturing method of this embodiment includes the steps of injecting beer or foam into a container, cooling the beer or foam into a slush state while stirring the beer or foam, injecting carbon dioxide gas into the slushy foam, .

Here, each process from discharging the foamed foam to discharging the foamed foam may be performed while the foamed foam is hermetically sealed with the outside air. In the closed state, the carbon dioxide gas in the container can not escape and the pressure is increased, so that the carbon dioxide gas can be better melted in the slush foam and the carbon dioxide gas content can be increased.

The slush foam to be topped on the beer can be manufactured through the above process.

The step of injecting includes extracting bubbles and beer from the beer coke and injecting the bubbles into the container, and injecting the beer extracted from the beer coke into the container while stirring and cooling the bubbles injected into the container.

As described above, only the bubbles are first introduced into the vessel, and the bubbles are stirred and cooled. Afterwards, the liquid beer is poured into the beaker at a later time and stirred and cooled to make the slush foam particles smoother than when the beer is stirred and cooled. It is possible to form the viscosity at an appropriate level.

In this embodiment, the time lag between the introduction of the bubbles into the container and the introduction of the beer may be 15 to 30 minutes. When the dispensing time difference of the bubbles and the beer is less than 15 minutes, the bubbles are mixed with the beer without being frozen and the slush foam particles become thick. If the parallax is longer than 30 minutes, the froth becomes too frozen and the beer and the foam are not properly mixed and the particles of the slush foam become rough and heavy.

The present manufacturing process further includes the step of adding an additive that adds flavor and aroma together with the beer when the beer is introduced.

The additive may be an undiluted solution of fruit containing sugar such as lemon or grapefruit, a syrup, a coffee stock solution, a sugar syrup, an aspartame liquid and the like.

The sugar of the additive makes slushy foam particles smooth and smooth and can increase the viscosity. When the slush foam thus produced is topped on the beer, the form of the slush foam placed like ice cream does not easily collapse, and the particles are soft and smoothly mixed with beer while being easily mixed with the beer. In addition, the taste and flavor of the additive can be added to the slush foam to enhance the taste and flavor of the slush foam, and the flavor and flavor of the beer can be improved while the foam is dissolved in the beer.

The bubbles and beer injected into the container are cooled to an appropriate temperature in the container and solidified into a slush state to produce a slush foam.

The slushing foam is collected toward the outlet by the screw blade rotating in the container, and finally discharged through the carbon dioxide gas injection process.

Carbon dioxide gas injection can be injected when the beer is cooled to the point of exit and is fully inflated to the slush state. The carbon dioxide gas injected into the slush serves to slush the slush foam particles. In addition, the carbon dioxide will melt into the slush. As described above, by injecting carbonic acid gas separately, the slush foam particles can be softly and lightly formed. In addition, by injecting carbon dioxide gas into the slush foam before discharging the slush foam over the beer, the carbonic acid content of the foam can be increased under atmospheric pressure. Therefore, the refreshing feeling of the bubbles can be enhanced, and even if the bubbles are mixed in the beer, the refreshing feeling of the beer can be maintained.

Thus, when the carbon dioxide gas is injected, the slush foam is discharged through the outlet of the vessel. The discharged slush foam is topped on the beer in the cup and served to the customers.

In this embodiment, a slush foam which is in the form of a creamy cream and has an appropriate viscosity can be manufactured and topped on the beer.

While the illustrative embodiments of the present invention have been shown and described, various modifications and alternative embodiments may be made by those skilled in the art. Such variations and other embodiments will be considered and included in the appended claims, all without departing from the true spirit and scope of the invention.
