AI Technical Summary
The existing beer filling process on can lines suffers from problems such as excessive foam at the can opening, high headspace oxygen content, and high production costs.
High-temperature and high-pressure steam is used instead of CO2 for foam breaking. High-temperature and high-pressure steam is blown into the mouth of the can using a foam breaking device and a steam supply device. The high-temperature and high-pressure steam jet blows away the large foam and punctures the gaps between the small foam, reducing the oxygen content in the headspace.
It effectively reduced the headspace oxygen content of canned draft beer, improved product quality, reduced production costs, and reduced carbon emissions.

TECHNICAL FIELD
[0001] The utility model belongs to the field of storage and arrangement device, concretely relates to a pop can line bubble breaking system. BACKGROUND
[0002] At present, packaging is the last link of beer production, and the increase of oxygen in the beer filling process will promote beer aging, accelerate the appearance of aging taste, and shorten the flavor shelf life. Therefore, controlling the total oxygen content in beer products plays a crucial role in controlling beer product quality stability and improving beer flavor. The pop can line beer filling can has a 15-20ml gap at the top, and foam will be generated at the filling port more or less due to high-speed filling of the filling machine. A large amount of air is hidden between the foams, which will affect the freshness of the beer if left in the beer. Therefore, CO2 is used to replace and blow clean the foam at the can port, and then CO2 is used to replace the air in this part of the can port to improve the freshness of the beer.
[0003] The CO2 blowing process of the commonly used pop can line cap machine mainly includes two parts. The first step is to use CO2 to blow the foam at the can port clean, and the second step is to use CO2 to blow and replace the air after blowing the foam at the can port clean to achieve a headspace oxygen content of ≤40ppb. For the blowing process of the above-mentioned equipment, as the service life of the filling machine increases, the performance of the equipment decreases, and there is more foam at the can port after filling. Among them, using CO2 to break the bubble can only blow away part of the large foam at the can port, and part of the small foam cannot be removed, which is not ideal and is not conducive to the subsequent CO2 blowing and replacement of the second part, resulting in high headspace oxygen of the pop can beer. In addition, using CO2 to break the bubble will increase the production cost, and the price of CO2 gas is 980 yuan / ton. Using CO2 to break the bubble causes 1kg / ton of wine to be consumed, so one ton of wine needs 0.98 yuan.

The height of the foam breaking device away from the can opening is arranged, which is beneficial to the steam injection to the beer liquid surface to break the foam, and the beer liquid is not blown out to cause excessive beer loss.
[0032] The high-temperature and high-pressure steam can effectively blow away the thick foam at the can opening, and reduce the influence of the foam on the CO2 blowing of the capping machine 6. The high-temperature and high-pressure steam can easily pierce the foam at the can opening, and stimulate the overflow of CO2 of the beer, thereby effectively reducing the oxygen content in the headspace of the can opening. By using the steam foam breaking, the headspace oxygen content of the live beer in the pop can 5 can be controlled within 20-40 ppb, while the headspace oxygen content of the live beer in the pop can 5 using the CO2 foam breaking is above 40 ppb, the optimization effect is obvious, the steam is cheaper than CO2, 0.851 yuan / ton of beer is saved in the production of one ton of beer, which is beneficial to energy saving and consumption reduction of enterprises, reduces carbon emissions, and has a positive effect on environmental protection.
[0033] Specifically, the foam breaking device comprises a shell 1, the upper end face and the lower end face of the shell 1 are parallel to each other, the air inlet 11 is arranged on the upper end face of the shell 1, the blowing port 12 is arranged on the lower end face of the shell 1, and the included angle between the upper end face and the vertical direction is 60-80°. The included angle between the upper end face and the vertical direction can be preferably 70°. That is, the included angle between the vertical axis of the foam breaking device and the can opening of the pop can 5 is 60-80°, which is beneficial to the steam blowing out excessive foam while piercing the foam at the can opening.
[0034] Specifically, the can 5 is transported to the capping machine 6 for capping process after eliminating the foam by the foam breaking system of the present application, and the horizontal distance between the shell 1 and the next process of the can 5 is 20-60 cm. That is, the distance between the foam breaking device and the capping machine 6 is about 20-60 cm, so that the high-temperature and high-pressure steam heat energy can be used to break the foam on the can mouth and stimulate the CO2 overflow of the beer before the next process, thereby effectively reducing the oxygen content in the headspace of the can mouth.
[0035] Specifically, the can 5 line foam breaking system of the present application further comprises a conveying pipeline 3, the steam supply device 2 is communicated with the air inlet 11 through the conveying pipeline 3, and an adjusting valve 31 for adjusting the flow is arranged on the conveying pipeline 3.

[0037] Specifically, the steam supply device 2 comprises a steam generator 21, an air outlet pipe 211 communicated with the inside of the steam generator 21 is arranged at the upper end of the steam generator 21, the air outlet pipe 211 is used for connecting with the conveying pipeline 3, and the steam pressure at the air outlet pipe 211 is 0.5-2.0 bar.
[0038] Specifically, a water inlet 212 communicated with the inside of the steam generator 21 is arranged on the steam generator 21, the steam supply device 2 further comprises a water inlet pipeline 4, one end of the water inlet pipeline 4 is communicated with a soft water supply end, the other end is communicated with the water inlet 212, and a heater 22 is arranged on the water inlet pipeline 4. The steam is secondary generated steam, that is, the soft water is first heated in the heater 22 to form hot soft water, and then is input into the steam generator 21 through a pipeline or a water pipe to be secondly heated to form steam. The steam pressure in the steam generator 21 can be set to 0.5-2.0 bar. The steam in the steam generator 21 enters the conveying pipeline 3 through the air outlet pipe 211, and the steam pressure can be reduced to 0.5-1.0 bar through the adjusting valve 31, so that the steam pressure at the blowing port 12 of the foam breaking device is reduced to an appropriate pressure, such as 0.5-1.0 bar. The steam blown out of the blowing port 12 is pure and non-polluted, and does not affect the flavor of the beer.

[0041] The 5-line foam breaking system of the present scheme uses soft water for secondary boiling to generate secondary pure steam, and the steam pressure in the steam generator 21 can be controlled at 2.0 bar. The steam passes through the regulating valve 31 to reduce the steam pressure at the foam breaking device to 0.5 bar to 1.0 bar. The steam foam breaking device is provided with a drain valve 32 in front to avoid the condensate water from being sprayed into the can 5. The angle between the foam breaking device and the vertical axis of the can 5 can be adjusted, the direction of the foam breaking device spray port is opposite to the running direction of the can 5, and the foam is blown to the back of the can 5. The distance between the foam breaking device spray port and the can opening height can be preferably 4 mm, and the distance between the foam breaking device and the capping machine 6 can be preferably 40 cm, which is the optimal distance for foam breaking. The steam foam breaking device spray port adopts two-side spray, and the spray angles are different, one side adopts inclined spray, and the other side adopts vertical spray, the two sides are staggered and complementary to each other, and the can opening can be fully covered by foam breaking.
[0042] In one embodiment, the can opening is broken by using the can line foam breaking system of the present scheme, which includes the following steps:
[0043] First, the soft water is heated by the heater 22, and then the pure steam is generated by the steam generator 21 for secondary heating, and the steam pressure is controlled at 1.0 bar. The steam pressure at the foam breaking device is controlled at 0.8 bar by the regulating valve 31, and the appropriate foam breaking pressure is adjusted according to the filling foaming condition. The high-temperature and high-pressure steam heat energy easily pierces the can opening foam, and at the same time stimulates the overflow of CO2 in beer, effectively reducing the oxygen content of the can opening headspace. The steam foam breaking device is about 4 mm away from the can opening, which is beneficial to the steam spray to the beer liquid surface to break the foam, and at the same time, the liquid is not blown out to cause excessive beer loss. The angle between the foam breaking device and the vertical axis of the can 5 is about 70 degrees, which is beneficial to the steam to blow out the excessive foam and pierce the can opening foam. The steam foam breaking device is about 40 cm away from the capping machine 6, and the appropriate time is reserved for the high-temperature and high-pressure steam heat energy to pierce the can opening foam, and at the same time stimulates the overflow of CO2 in beer, effectively reducing the oxygen content of the can opening headspace. The steam foam breaking device is provided with a drain valve 32 in front to avoid the condensate water from being dropped into beer, affecting the flavor of beer. The steam foam breaking device is automatically controlled, and the steam foam breaking is started and stopped by using the signal of the filling machine outlet induction probe. When the filling is stopped, the steam foam breaking is automatically closed, thereby saving steam consumption.
[0044] Embodiment:
[0045] The above-mentioned way is used to produce and extract 6 bottles of sample 6.
[0046] Comparative example 1:
[0047] The sample of the control example 1 is produced and extracted by using the traditional CO2 foam breaking method.
[0048] The control example 2:
[0049] In the control example 2, soft water is used for the secondary heating to produce pure steam, and the pressure is controlled at 1.0 bar. The steam foam breaking pressure is controlled at 0.8 bar, and the appropriate foam breaking pressure is adjusted according to the filling foaming condition. A drain valve 32 is arranged in front of the steam foam breaking device, and the foam breaking device is automatically controlled. The steam foam breaking is started and stopped by using the filling machine outlet induction probe signal. When the filling is stopped, the steam foam breaking is automatically closed, thereby saving the steam consumption. The steam foam breaking device is about 8 mm away from the can opening, so that the steam is sprayed to the beer liquid surface to break the foam. The upper end surface of the foam breaking device is about 90 degrees in angle with the vertical axis of the can 5 opening. The steam foam breaking device is about 80 cm away from the capping machine 6. The sample of the control example 2 is produced and extracted.
[0050] The headspace oxygen content of the samples in the above examples and the control examples 1 and 2 is compared, and the headspace oxygen detection condition of the samples is shown in Table 1.
[0051]
[0052] Table 1. Sample headspace oxygen detection table
[0053] According to the results of the examples and the control examples 1 and 2 shown in Table 1, in the above examples, the headspace oxygen of the samples produced by using the can line foam breaking system of the present scheme to break the foam of the can opening is controlled within 40 ppb, and the average value is only 30.66. The headspace oxygen of the samples produced by using the traditional CO2 foam breaking method in the control example 1 is all above 40 ppb, and the average value is 48.50. The steam foam breaking method is used in the control example 2, but the height, angle and position of the foam breaker are not set according to the present scheme. The headspace oxygen of the samples extracted after production is all above 40 ppb, and the average value is 43.83.
[0054] According to the above headspace oxygen detection results, the headspace oxygen of the samples produced and extracted by using the can line foam breaking system of the present scheme is obviously better than that of the traditional CO2 foam breaking, and it is more beneficial to prolong the best drinking period of beer.
[0055] The other contents of the can line foam breaking system are known in the prior art, and will not be described here.
[0056] The above is only a preferred embodiment of the present utility model, and does not limit the present utility model in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present utility model still belongs to the scope of the technical scheme of the present utility model.
