Description

[Detailed explanation of the invention] [Industrial application field] This invention is mainly used to instantly produce a soft drink at a predetermined concentration and amount by using pressurized carbon dioxide gas pressure to combine concentrated liquid and diluted water at stores. The present invention relates to a device for providing the following, and more particularly, to a device that prevents bacteria from growing inside the device when not in use.

[Conventional technology]

For sale, the common method is to dilute the concentrate to make a soft drink of a predetermined concentration and store it for that purpose. Since there are problems with hygiene, preservation of the container, and storage location, a method is used to dilute it at the time of sale, but from a hygiene perspective when the device is not in use, it takes a lot of effort to take precautions after each use. Currently, the remaining liquid is disposed of and cleaned using water.

[The problem that the idea attempts to solve]

At the time of sale, diluted water is pumped into the concentrated liquid (concentrated syrup) of the soft drink using the pressure of carbon dioxide gas in a separate carbon dioxide gas cylinder, and the two liquids are mixed to produce a soft drink with a predetermined concentration. It is undesirable from a hygienic point of view to leave the equipment in place without cleaning it after sales of soft drinks have ended, so remove the concentrate tank and store the contents in an appropriate manner. Although it is natural to clean the tank, there are still parts in the piping of the entire device that require cleaning after the tank is removed. In other words, syrup remains in the concentrate feed pipe from the concentrate tank to the mixing nozzle and in the mixing nozzle.
In addition to the sanitary aspects of bacterial growth, the precipitation of precipitates may even cause problems such as clogging of the concentrated liquid pressure feed pipe or the liquid passage of the mixing nozzle.

Therefore, we have eliminated the need to spend time and effort cleaning the liquid remaining in the equipment and concentrated liquid pressure delivery pipe after use, and can be cleaned in an extremely hygienic manner by simply changing the piping connections, while also preventing the invasion and proliferation of bacteria. It is necessary to keep this device in a safe environment so that it can be used again safely.

[Means for solving problems]

This idea injects pressurized carbon dioxide from a carbon dioxide gas cylinder into the concentrate tank and dilution water tank, and uses this gas pressure to forcefully feed the concentrate and dilution water to a mixing nozzle to mix the concentrate and dilution water. In an apparatus for producing soft drinks of a predetermined concentration, a cleaning connector having a branch pipe connection port is provided in the middle of the dilution water pressure feed pipe, and the connection point of the concentrate pressure feed pipe with the concentrate tank is
This is a bacteria control device for piping that can be selectively connected to a concentrated liquid tank and a branch connection port of a cleaning connector.

[Effect]

After removing the concentrated liquid pressure feeding pipe of this invention from the connector with a stop valve of the concentrated liquid tank, this concentrated liquid pressure feeding pipe is connected to the branch pipe connection port of the cleaning connector, and all of the diluted water is supplied with carbon dioxide gas pressure from the carbon dioxide gas cylinder. After flowing out from the mixing nozzle through the dilution water pressure pipe and the concentrated liquid pressure pipe connected to the branch connection port of the cleaning connector, close the stop valve just before the mixing nozzle. Not only is the purpose of cleaning achieved by replacing the gas with gas, but the inside of both pressure feed pipes is pressurized, so there is no possibility of bacteria entering from other sources, and the inside of the equipment's pipes is kept extremely sanitary. I can do it.

〔Example〕

Next, this invention will be explained with reference to drawings showing embodiments. Figure 1 is a piping diagram during the sales of soft drinks, in which the concentrate tank 1 is filled with the raw solution of soft drinks, and the concentrate delivery pipe is inserted into the tank 1 with its tip close to the bottom of the tank. 1a, and its upper end is connected to a connector 12 with a stop valve attached to the top surface of the tank, and this part connects the concentrated liquid pressure feed pipe 9.
It is designed so that it can be separated. A separate dilution water tank 2 is filled with clean water for dilution, and like the concentrate tank 1, this dilution water tank 2 is also provided with a dilution water delivery pipe 2a whose tip is inserted close to the bottom of the tank. A carbon dioxide gas pressure feeding pipe 7 from the carbon dioxide gas cylinder 3 is connected to the upper edges of both the tanks 1 and 2 via respective connectors 10a and 10c. The concentrate pressure feed pipe 9 of the concentrate tank 1 and the dilution water pressure pipe 8 of the dilution water tank 2 are both provided with stop valves 6a and 6 provided near the mixing nozzle 4.
b, but a cleaning connector 5 is interposed in the middle of the dilution water pressure feed pipe 8 from the dilution water tank 2, and this cleaning connector 5
has multiple branch pipe connection ports 11, 11 on its side edges.
will be established. After completion of the dilution work of the soft drink, the concentrated liquid pressure feeding pipe 9, which is removed from the stop valve equipped connector 12 of the concentrated liquid tank 1, is connected to the branch pipe connection ports 11, 11 as shown by dotted lines. In addition, another branch pipe connection port 11 is provided as a reserve for another concentrated liquid, but in any case, the connector 12 with a stop valve and the branch pipe connection ports 11, 11 are separated from each other, and at the same time, either opening is opened. The side is also closed.

In addition, a stop valve 6c is provided on the outlet pipe 3a of the carbon dioxide gas cylinder 3, and a connector 10c is provided on the carbon dioxide gas pressure feed pipe 7 and the dilution water pressure feed pipe 8 of the dilution water tank 2.
10b is attached so that this tank can be separated. The carbon dioxide gas pressure feeding pipe 7 to the concentrated liquid tank 1 is equipped with a connector 10a on the tank side and a stop valve 6d on the base side thereof.

Next, the operation of this device will be explained. In this device, which is piped as shown in FIG. 1, by opening the stop valve 6c of the carbon dioxide gas cylinder 3 to send out carbon dioxide gas, and by opening the stop valve 6d at the inlet of the concentrate tank 1, both stop valves 6a provided near the mixing nozzle 4,
By adjusting the opening degree of the carbon dioxide gas cylinder 6b, a soft drink of the desired concentration is obtained, which is then received in the receiver 13 and sold. Close the stop valve 6d and close the tank 1 as shown in FIG.
Connector 10a and connector 1 with stop valve

The gas pressure leads to the dilution water delivery pipe 2a, the dilution water pressure pipe 8, and the cleaning connector 5, and within this cleaning connector 5, there is a path leading to the mixing nozzle 4 via the stop valve 6b, and a route from the branch pipe connection port 11 to the concentrated liquid pressure transmission pipe 9. The dilution water is discharged from each mixing nozzle 4, and in particular the branch pipe connection port 1.
