Description

  The present invention relates to a carbonated beverage production facility and production method.

Carbonated beverages are generally produced by mixing water and syrup to dissolve carbon dioxide.
Production equipment for carbonated drinks uses water and syrup as raw materials, a deaerator that degassed from water, a blender that mixes water and syrup at a predetermined mixing ratio, and a predetermined amount of carbonic acid in the mixture obtained by the blender. And a carbonator for dissolving the gas. Water is deaerated in order to avoid gas such as oxygen contained in water from affecting the quality of the beverage.
If you have finished producing carbonated beverages, for example, in units of tens of thousands of bottles by mixing water and syrup and dissolving carbon dioxide with the above production equipment, wash the production equipment and use different types of syrup Shift to the production of carbonated beverages using

Even after the water used for the cleaning is discharged from the drain after the manufacturing facility is cleaned, a considerable amount of water remains on the bottom of the tank and the connection part of the pipe constituting the manufacturing facility. Since the concentration of syrup in the mixed solution is lowered by the amount of the remaining water, the defective solution that has not reached the prescribed syrup concentration is discarded after the start of production. When the prescribed syrup concentration is reached, the disposal is terminated, and a carbonated beverage having a prescribed syrup concentration and a prescribed carbon dioxide volume is produced.
The amount of liquid discarded after the start of production reaches, for example, thousands of bottles. In particular, in the recent production of a wide variety of small lots, an amount of liquid that cannot be ignored with respect to the total amount of products is discarded every time the item to be manufactured is switched.

  Then, an object of this invention is to provide the manufacturing apparatus and manufacturing method of carbonated drink which can be utilized for a product, without discarding a defective liquid.

  The present invention relates to a carbonated beverage production facility using water and syrup as raw materials, a deaerator for degassing water, a blender for mixing water deaerated by the deaerator, and syrup, and a blender A carbonator for dissolving carbon dioxide gas in the mixed liquid obtained by the above, a return path for sending the liquid dissolved by the carbonator to the deaerator, a switching unit for switching whether to use the return path or not, It is characterized by providing.

The production facility of the present invention can be operated so that a defective liquid having a low concentration generated when operated after washing is returned to the deaerator using the return path.
The liquid returned through the return path is introduced into the blender through the deaeration device. Syrup is added to the liquid with a blender, and carbon dioxide is dissolved by a carbonator.
When the syrup concentration of the liquid returned through the return path gradually increases as the replacement of water remaining in the facility with syrup progresses, when the prescribed syrup concentration is reached, the use of the return path is terminated. Transition to steady operation is possible.

In the present invention, since the liquid returned by the return path is introduced into the degassing device, the carbon dioxide dissolved in the liquid is removed by the degassing device, and the liquid not containing carbon dioxide is supplied to the blender. And introduced. Even if syrup is added to the liquid with a blender, the gas volume is unchanged because it originally does not contain carbon dioxide. That is, a return liquid having a specified gas volume can be obtained by dissolving a certain amount of carbon dioxide gas by the carbonator regardless of the syrup concentration in the liquid returned by the return path.
If a defective liquid in which carbon dioxide gas is dissolved is introduced into the blender downstream from the deaerator, the gas volume in the liquid changes as syrup is added to the liquid. Since the gas volume cannot be measured instantaneously, it is impossible to control the carbon dioxide injection amount by the carbonator to follow the change in the gas volume. In other words, even if the defective liquid is returned to the blender, it cannot be adjusted to the specified concentration. Consequently, the amount of the defective liquid that occurs before the water remaining in the facility is replaced with syrup is not drained. It must be discarded more.
On the other hand, according to the present invention, since the defective liquid generated after the cleaning of the manufacturing equipment can be reprocessed and used for products without discarding as much as possible, the loss of raw materials can be eliminated and the yield can be improved. it can.

  In the present specification, a liquid from which carbon dioxide gas has been removed by a deaeration device is defined as “a liquid not containing carbon dioxide gas”.

The carbonated beverage production facility of the present invention preferably includes a densitometer that measures the concentration of the liquid introduced into the blender after being deaerated by the deaerator.
This concentration meter can accurately measure and measure the concentration of the liquid returned by the return path without hindering the bubbles of carbon dioxide gas, so the amount is sufficient for the blender to be short of the prescribed syrup concentration. By mixing with the syrup, a liquid having a prescribed syrup concentration can be reliably obtained.
Furthermore, if the densitometer shows a prescribed syrup concentration, the use of the return path can be terminated and the operation can be shifted to a steady operation.

  The carbonated beverage production facility of the present invention can be configured such that the return path leads to a water introduction path for introducing water into the deaeration device.

The carbonated beverage manufacturing equipment of the present invention includes a bypass path for bypassing the carbonator from the discharge side of the blender, a second return path for returning the mixed liquid obtained by the blender toward the introduction side of the blender, and a second return A second switching unit that switches whether the route is used or not used may be provided.
In addition to the production of carbonated beverages, such production equipment can produce non-carbonated beverages that do not dissolve carbon dioxide in the mixed liquid obtained by the blender by using a bypass route.
When producing a non-carbonated beverage, the second return path is used instead of the above return path. The liquid returned through the second return path can be used for a product by adjusting to a specified concentration with a blender.

  The present invention relates to a method for producing a carbonated beverage using water and syrup as raw materials, a deaeration device for deaeration from water, a blender for mixing water and syrup deaerated by the deaeration device, and a blender. A first step of cleaning a manufacturing facility comprising a carbonator for dissolving carbon dioxide in the obtained mixed liquid, and a return path for sending a liquid in which carbon dioxide is dissolved by the carbonator toward a deaerator; The second step of introducing the liquid into the return path when the liquid that does not reach the specified syrup concentration is created by mixing the water used for cleaning, and the production facility is operated using the return path. And a fourth step of operating the manufacturing facility without using the return path.

  In the method for producing carbonated beverages of the present invention, if the concentration of the liquid introduced into the blender reaches the prescribed syrup concentration after being deaerated by the deaerator, the third step to the fourth step are performed. It is preferable to migrate.

  According to the production equipment and production method for carbonated beverages of the present invention, even if carbon dioxide gas is contained in a defective liquid that does not reach the prescribed syrup concentration, it can be used for a product without discarding the defective liquid.

It is a figure which shows the manufacture procedure of a product. It is a schematic diagram which shows the manufacturing equipment of the carbonated beverages concerning 2nd Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[First Embodiment]
The manufacturing equipment 10 of 1st Embodiment shown in FIG. 1 uses a syrup and water as a raw material, and manufactures carbonated drink by dissolving carbon dioxide gas in those liquid mixture.

The production facility 10 includes a syrup supply source 11, a water supply source 12, a deaerator 13 (a deaeration device) for degassing water, a blender 14 for mixing syrup and water, and carbon dioxide gas in a mixed solution of syrup and water. Is provided with a carbonator 15 for dissolving the carbon dioxide, a post-processing device 16, and a return path 20 for operating in a reuse mode to be described later.
Each element which comprises the manufacturing equipment 10 is connected by piping. In addition to those shown in the figure, the pipe can be provided with a pump, a valve, a drain, and the like where necessary.

The syrup supply source 11 supplies a predetermined syrup to the blender 14.
The syrup supply source 11 and the blender 14 are connected by a syrup introduction path 17. The syrup introduction path 17 is provided with a syrup supply valve 171 that is opened and closed to switch between supply and stop of supply of syrup.

The water supply source 12 supplies water for diluting the syrup to the blender 14 via the deerator 13.
The water supply source 12 and the deerator 13 are connected by a water introduction path 18. The water introduction path 18 is provided with a water supply valve 181 that is opened and closed to switch between water supply and supply stop.

The deaerator 13 removes a gas such as oxygen dissolved in the water supplied from the water supply source 12. Here, the solubility of the gas is proportional to the pressure. Moreover, the solubility of gas becomes small, so that temperature is high. Therefore, as the deerator 13, a vacuum tank is used to reduce the pressure and water is sprinkled in the tank, or the dissolved gas is separated from the water by heating the water using a heat exchanger. What to remove can be employed. In addition, various known deerators such as those using a deoxygenation film can be employed.
Water from which the gas has been removed by the deerator 13 is supplied to the blender 14.

The blender 14 mixes the syrup supplied from the syrup supply source 11 and the water deaerated by the deerator 13 at a predetermined mixing ratio. As a result, a liquid mixture having a prescribed concentration determined for the product is produced. For example, syrup and water are mixed at a mixing ratio of 1: 4.
As the blender 14, various known blenders can be employed.

The blender 14 includes a syrup metering valve 141 for metering syrup supplied from the syrup supply source 11 and a water metering valve 142 for metering water deaerated by the deerator 13. The syrup metering valve 141 and the water metering valve 142 each have an opening set based on the mixing ratio, and allows liquid (syrup, water) to pass through at a predetermined flow rate corresponding to the set opening.
At least one of the syrup metering valve 141 and the water metering valve 142 has a variable opening. The mixing ratio can be changed by controlling at least one of the opening degrees.

In order to manage the product at a constant concentration, the blender 14 includes a Brix meter 14x that measures the syrup concentration of a mixed solution in which syrup and water are mixed.
The concentration of syrup in the present embodiment means Brix. Brix refers to the weight content of soluble solids in a liquid. Brix in syrup (sucrose aqueous solution) refers to the weight of sucrose contained in a unit weight (for example, 100 g) of the sucrose aqueous solution.
As the Brix meter 14x, one that calculates Brix based on the measured value of the refractive index or density of the liquid can be used.
In addition, it is preferable that an introduction Brix meter 24x for measuring the syrup concentration of the liquid introduced into the blender 14 after being deaerated by the deerator 13 is provided.
The introduction Brix meter 24x is provided between the deerator 13 and the blender 14, and measures the syrup concentration of the return liquid deaerated by the deerator 13.
As the introduction Brix meter 24x, the one that calculates Brix based on the measured value of the refractive index or density of the liquid can be used in the same manner as the Brix meter 14x described above.

The carbonator 15 dissolves carbon dioxide gas (CO ₂ gas) in the mixed liquid sent from the blender 14 by an amount corresponding to a predetermined gas volume.
In order to keep the gas volume of the product constant, the carbonator 15 includes a gas volume meter 151 that measures the carbon dioxide volume of the mixed solution in which the carbon dioxide gas is dissolved.
The gas volume is obtained by dividing the volume of carbon dioxide dissolved in the liquid by the volume of the liquid with respect to carbon dioxide under the condition of 15.6 ° C. at 1 atm.
The gas volume meter 151 includes a container for storing a liquid, a temperature sensor, a pressure sensor, and an arithmetic unit. After the container is shaken, the cover of the container is removed and the gas volume of the carbon dioxide gas separated from the liquid is set to 1. It is obtained by correcting to the condition of 15.6 ° C. at atmospheric pressure.

  As the carbonator 15, various known carbonators can be employed.

  In the middle of the path 19 that connects the blender 14 and the carbonator 15, although not shown, a valve, a pump, a cooler that cools the mixed liquid by heat exchange with air or water in order to make the carbon dioxide easily dissolve, etc. Can be provided.

  The carbonator 15 and the post-processing device 16 are connected by a liquid feeding path 161. The liquid supply path 161 is provided with a liquid supply valve 162 that switches between liquid supply from the carbonator 15 to the post-processing device 16 and liquid supply stop.

  The post-processing device 16 corresponds to a tank that temporarily stores the manufactured liquid or a filler that fills a bottle with the manufactured liquid. The aftertreatment device 16 can be constituted by both the tank and the filler. Moreover, the post-processing apparatus 16 can be comprised including the apparatus which performs processes, such as heat sterilization, as needed.

Now, when the manufacturing equipment 10 is fixedly cleaned, water remains on the bottom of the tank, the joint portion of the pipe, and the like even after the water used for cleaning is discharged from the drain. When the production facility 10 is operated in this state, water remaining in the facility is mixed into the product, and for a while after the start of production, a defective liquid having a concentration lower than the prescribed syrup concentration determined for the product is produced. .
The manufacturing facility 10 of this embodiment sends the defective liquid that has not reached the specified syrup concentration from the downstream of the carbonator 15 toward the deerator 13 through the return path 20 without being discarded as much as possible.
Hereinafter, the term “return liquid” simply means a defective liquid introduced into the return path 20.

The return path 20 extends from the start end 20A connected to the liquid supply path 161 downstream of the carbonator 15 to the end end 20B connected to the water introduction path 18. The start end 20 </ b> A is located upstream of the liquid supply valve 162. The terminal end 20B is located downstream of the water supply valve 181.
A valve 21 is provided on the start end 20A side. A valve 22 is provided on the end 20B side. The valves 21 and 22 are opened and closed to switch whether or not to introduce the liquid in which the carbon dioxide gas is dissolved by the carbonator 15 into the return path 20. Whether to use the return path 20 or not is switched by valves 21 and 22.
The return path 20 is provided with a drain 25 for discharging the return liquid in the return path 20, and a liquid feed pump 23 is installed as necessary.
Even if the liquid feed pump 23 is not installed, the liquid can be fed toward the deerator 13 based on the pressure difference between the pressure (high pressure) at the outlet of the carbonator 15 and the pressure of the deerator 13 lower than that. If the piping of the return path 20 rises high or the length of the piping of the return path 20 is very long, the liquid feed pump 23 may be installed.

  A Brix meter 14x that measures the syrup concentration of the mixture of syrup and water can be used to determine whether to end the reuse mode operation using the return path 20 and shift to the steady mode operation. .

The manufacturing facility 10 sequentially manufactures a wide variety of products in small quantities based on the manufacturing plan. If a certain product is manufactured in a predetermined amount, the manufacturing equipment 10 is cleaned in place. Thereafter, the syrup supplied by the syrup supply source 11 is changed to a different type, and the process proceeds to manufacture of the next product.
In the present embodiment, after the manufacturing facility 10 is cleaned, the manufacturing facility 10 is operated in a reuse mode in which the defective liquid produced by operating the manufacturing facility 10 is returned. The return path 20 described above is used in the reuse mode. After the reuse mode operation, the operation is performed in the steady mode without using the return path 20.

As shown in FIG. 2, after performing the stationary cleaning (step S1) of the manufacturing facility 10, the manufacturing facility 10 is operated (step S2).
Thereafter, the operation is performed in the reuse mode (step S3).
After performing the reuse mode, the production mode is continued by switching to the steady mode (step S4). If the product is manufactured by a predetermined amount, the process returns to step S1, and the process is repeated in the order of steps S1 to S4.

First, the steady mode operation (step S4) of the manufacturing facility 10 will be described with reference to FIG. Thereafter, the reuse mode operation (step S3) will be described with a description of stationary cleaning (step S1) and preparation for reuse (step S2).
During the steady mode operation (step S4), the syrup supply valve 171 is opened and the water supply valve 181 is also opened. In FIG. 1, the flow of the liquid in the steady mode is indicated by solid line arrows. Dashed arrows indicate the flow of the liquid in the reuse mode.
During the steady mode operation, the return path 20 is not used, and the liquid is fed from the carbonator 15 to the post-processing device 16. Therefore, the liquid supply valve 162 is opened and the valves 21 and 22 of the return path 20 are closed.

The syrup introduced from the syrup supply source 11 into the syrup introduction path 17 is supplied to the blender 14.
On the other hand, the water introduced from the water supply source 12 to the water introduction path 18 is deaerated by the deerator 13 and then supplied to the blender 14.
The blender 14 mixes syrup and water at a mixing ratio determined by the opening degree of each of the syrup metering valve 141 and the water metering valve 142. By continuously acquiring the concentration measured by the Brix meter 14x, the syrup concentration of the liquid mixed by the blender 14 can be managed constant.

The liquid mixture of syrup and water is sent to the carbonator 15. The carbonator 15 dissolves an amount of carbon dioxide gas corresponding to the determined gas volume in the mixed solution. By continuously acquiring the gas volume measured by the gas volume meter 151, the gas volume of the liquid discharged from the carbonator 15 can be managed uniformly.
This completes the product liquid. The completed liquid is sent to the post-processing device 16 where appropriate processing such as filling into a bottle and storage in a tank is performed.

When the manufacture of the product by a predetermined amount is completed by the steady mode operation (step S4), the operation of the manufacturing facility 10 is stopped and the manufacturing facility 10 is fixedly cleaned using hot water or the like (step S1). At this time, the valves 21 and 22 are opened, and the entire manufacturing facility 10 including the return path 20 is cleaned.
Thereafter, the syrup supplied by the syrup supply source 11 is changed to a different type, and the production facility 10 is operated to prepare for reuse (step S2). At this time, the liquid supply valve 162 is closed in advance so that the defective liquid produced by mixing the water remaining in the deerator 13, blender 14, and carbonator 15 is introduced into the return path 20. Keep open.

If the defective liquid is introduced from the carbonator 15 to the return path 20 as a return liquid, the water supply valve 181 is closed to shift to the reuse mode operation (step S3).
As can be seen from the flow of the liquid indicated by the broken-line arrows in FIG. 1, during the reuse mode operation, the liquid supply valve 162 is closed, the valves 21 and 22 of the return path 20 are opened, and the water supply valve 181 is closed. The syrup supply valve 171 is kept open. The liquid feed pump 23 is operated during the reuse mode operation.
The return liquid introduced into the return path 20 is introduced into the deerator 13 instead of the water supplied from the water supply source 12 after water remaining in the return path 20 is mixed. The return liquid is deaerated by the deerator 13 and then mixed with the syrup by the blender 14, and the carbon dioxide gas is dissolved by the carbonator 15.

The return liquid introduced into the return path 20 contains carbon dioxide gas dissolved by the carbonator 15. Since the carbon dioxide in the liquid is removed from the liquid by the deerator 13, a return liquid that does not contain carbon dioxide is introduced into the blender 14. Note that oxygen gas or the like that can be dissolved in the remaining water mixed in the return liquid is also deaerated by the deerator 13.
Then, the blender 14 adds the syrup supplied from the syrup supply source 11 to the return liquid and mixes them. Here, by controlling the opening degree of the syrup metering valve 141 in accordance with the concentration measured by the Brix meter 14x, it is possible to add a variable amount of syrup to the return liquid that is insufficient for the return liquid. .

During the reuse mode operation, the syrup concentration of the return liquid increases as the replacement of the remaining water with the syrup proceeds. If the Brix meter 14x shows the prescribed syrup concentration, the replacement with the syrup is completed over the range of the deerator 13, the blender 14, and the carbonator 15. Therefore, if the Brix meter 14x shows a prescribed syrup concentration, the necessary valves are opened and closed, and the recycle mode operation is shifted to the steady mode operation (step S4). The liquid whose syrup concentration is guaranteed by the Brix meter 14 x is sent to the post-processing device 16 through the carbonator 15.
The return liquid remaining in the return path 20 is discharged from the drain 25.

  As described above, the carbon dioxide in the liquid is removed by the deerator 13 so that the carbon dioxide is mixed into the air in the tank of the deerator 13. Here, the amount of gas deaerated by the deerator 13 is determined individually for each gas based on the solubility proportional to the partial pressure of each of oxygen gas, carbon dioxide gas, and the like. Even if carbon dioxide gas is mixed in the deerator 13, the degassing performance of each gas is not affected.

According to the present embodiment described above, by operating the manufacturing facility 10 in the reuse mode using the return path 20, a defective liquid having a low concentration generated when the manufacturing facility 10 is operated after cleaning is discarded as much as possible. It can be used for products without doing.
Here, in using the defective liquid containing carbon dioxide gas, it is significant that the defective liquid is returned to the deerator 13.

  If the defective liquid containing carbon dioxide is returned downstream from the deerator 13 and introduced into the blender 14, the return liquid containing carbon dioxide is introduced into the blender 14. When the syrup is added to the return liquid by the blender 14, the gas volume of the return liquid changes. Unlike measurement of the syrup concentration, it is difficult to measure the gas volume in real time, and therefore, it is impossible to perform control for changing the amount of carbon dioxide gas to be dissolved. For this reason, even if the defective liquid containing carbon dioxide gas can be adjusted to the specified syrup concentration, it cannot be adjusted to the specified gas volume and must be discarded.

On the other hand, in this embodiment, the defective liquid containing carbon dioxide is returned toward the deerator 13 through the return path 20, and the carbon dioxide is removed from the return liquid by the deerator 13. Therefore, even if syrup is added by the blender 14, the gas volume does not change because the carbon dioxide gas is not originally contained. In other words, a certain amount of carbon dioxide gas is dissolved by the carbonator 15 with respect to the return liquid whose gas volume has been reset by the deerator 13 regardless of the syrup concentration of the return liquid, thereby obtaining a return liquid having a prescribed gas volume. it can.
Therefore, according to the present embodiment, since the return liquid prepared to a specified syrup concentration by the blender 14 and adjusted to the specified gas volume by the carbonator 15 can be used for the product, waste of raw materials is eliminated and the yield is improved. Can do.

Further, after deaeration by the deerator 13, the concentration of the return liquid and the measurement of the return liquid can be accurately performed by the Brix meter 14x without hindering the bubbles of carbon dioxide gas. By adding as much syrup as the deficiency in the return solution, the concentration of the return solution can be reliably adjusted to the specified syrup concentration.
Furthermore, when the introduction Brix meter 24x is provided, the blender 14 can perform mixing at a more accurate mixing ratio.

  The return path 20 of the present embodiment has a starting end 20A between the carbonator 15 and the post-processing device 16, but at a position downstream thereof, for example, before the product liquid is filled in the bottle in the post-processing device 16. You may have the start end 20A in the position. In this case, the return liquid introduced into the return path 20 can be used for the product.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG.
Below, it demonstrates centering on difference with 1st Embodiment. The same code | symbol is attached | subjected to the structure similar to 1st Embodiment.
The production facility 10α of the second embodiment shown in FIG. 3 can produce beverages that do not contain carbon dioxide gas in addition to the production of carbonated beverages.
In addition to the same configuration as that of the carbonated beverage manufacturing equipment 10 described above, the manufacturing equipment 10α is a blender that bypasses the carbonator 15 from the discharge side of the blender 14 and the mixed liquid obtained by the blender 14. 14 and a return path 40 returning toward the introduction side.
In FIG. 3, the flow of the liquid when the return path 40 is used is indicated by a one-dot chain line arrow.

The bypass path 30 sends the mixed liquid obtained by the blender 14 to the post-processing device 16 by bypassing the carbonator 15.
In a joint portion between the path 19 for feeding the liquid from the blender 14 to the carbonator 15 and the bypass path 30, liquid feeding from the blender 14 to the carbonator 15, and from the blender 14 to the post-processing device 16 via the bypass path 30 are performed. A switching valve 31 for switching between liquid feeding is provided.

The return path 40 extends from the start end 40A connected to the path 19 connecting the blender 14 and the carbonator 15 to the end 40B connected to the path connecting the deerator 13 and the blender 14.
A valve 41 is provided on the start end 40 </ b> A side of the return path 40. A valve 42 is provided on the end 40 </ b> B side of the return path 40. The valves 41 and 42 are opened and closed to switch whether or not to introduce the liquid mixture obtained by the blender 14 into the return path 40.
Whether to use the return path 40 or not is switched by valves 41 and 42.
The return path 40 is provided with a pump 43 that sends the return liquid introduced into the return path 40 toward the blender 14 and a drain 45 that discharges the return liquid in the return path 40.

When manufacturing a carbonated beverage after washing the production facility 10α, the return path 20 may be used to perform the same processing as in steps S1 to S4 (FIG. 2) described above.
When manufacturing a non-carbonated beverage after washing the production facility 10α, the return path 40 may be used in place of the return path 20 to perform the same processing as in steps S1 to S4 described above.
Specifically, after cleaning (step S1), the valves 41 and 42 are operated so that the mixed liquid is introduced from the blender 14 to the return path 40, and the manufacturing facility 10α is operated. Then, a defective liquid that does not reach the prescribed syrup concentration is produced and introduced into the return path 40 (step S2). Now that the preparation for reuse is complete, the water supply valve 181 is closed, the pump 43 is operated, and the return liquid introduced into the return path 40 is operated in a reuse mode in which it is returned upstream of the blender 14 instead of water. (Step S3). The return liquid is mixed with an appropriate amount of syrup according to the concentration measured by the introduction Brix meter 24x. If the introduced Brix meter 24x shows the prescribed syrup concentration, the replacement of the remaining water after washing with the syrup is complete, so the valves 41 and 42 are closed, the water supply valve 181 is opened, and the operation enters the steady mode. Production of non-carbonated beverages is continued (step S4).

  According to the manufacturing facility 10α of the second embodiment, in addition to reusing a defective liquid containing carbon dioxide, it is possible to reuse a defective liquid not containing carbon dioxide.

  Although the return path 40 of the present embodiment communicates between the deerator 13 and the blender 14, the return path 40 may communicate upstream of the deerator 13. As a result, oxygen gas or the like that can be dissolved in the remaining water mixed in the return liquid introduced into the return path 40 is also deaerated by the deerator 13, which can contribute to ensuring the quality of the product.

  In each of the above embodiments, an example in which products of different items are manufactured while sandwiching the cleaning of the manufacturing equipment is shown, but the cleaning of the manufacturing equipment is not only at the time of switching the items to be manufactured, It is also done at the end of work. Steps S2 to S4 can be performed following the step S1 of the cleaning performed at the start and end of work. Therefore, the manufacturing facilities 10 and 10α of the above embodiments are also effective when manufacturing products of the same item.

In addition to the above, as long as the gist of the present invention is not deviated, the configurations described in the above embodiments can be selected or changed to other configurations as appropriate.
What are the pipes and valve configurations of the manufacturing facilities 10 and 10α of the above embodiments? It can be modified into various forms.
For example, the return path 20 does not necessarily have to communicate with the water introduction path 18. The end 20 </ b> B side of the return path 20 may communicate directly with the deerator 13 separately from the water introduction path 18.
Further, instead of providing the valve 21 of the return path 20 and the liquid supply valve 162, liquid supply from the carbonator 15 to the post-processing device 16 is provided at the joint between the start end 20 </ b> A of the return path 20 and the liquid supply path 161. It is also possible to provide a switching valve that switches between liquid delivery from the carbonator 15 to the return path 20.

  Furthermore, the present invention allows the water supplied from the water supply source 12 to be introduced into the deerator 13 together with the return liquid without closing the water supply valve 181 while operating the manufacturing facility in the reuse mode.
