Abstract

PROBLEM TO BE SOLVED: To provide a device which washes a syrup line with BIB sanitarily and efficiently by utilizing sanitary drink water stored in a vending machine as washing water. SOLUTION: A vending machine has an additional three-forked cock 19 on an exit pipe of a water storage 2 and a washing water hose 20 taken out from a diverging port 19a of the cook 19. When a syrup line 11 is washed, BIB 1 is removed from BIB connector 14 connected to an entrance of the syrup line 11, and BIB 1 is replaced with a hose joint 21 which is connected to the end of the hose 20. When the hose joint 21 joins the hose 20 to the connector 14 and the diverging port 19a is opened and a syrup pump 13 is operated, stored water in the water storage 2 is sucked in the hose 20 and flows in the line 11 and conducts washing.

The present invention relates to a method for cleaning a syrup line for supplying a syrup beverage using B (Bag In Box), and a cleaning circuit thereof.

[0002]

2. Description of the Related Art First, a syrup beverage system in a cup type vending machine described above is shown in FIG. In the figure, 1 is a BIB (Bag In Box) containing concentrated syrup, 2 is a water reservoir for storing tap water supplied from a tap, 3 is a carbonator for producing carbonated water, 4 is a cooling water tank, 4a is a cooling water tank 4 A refrigerator for cooling the water stored in the cooling water tank 4; an agitator 5 for stirring the cooling water stored in the cooling water tank 4; a bend stage 6 leading to a product outlet of the vending machine;
8 is a water pump connected to a cold water line 9 drawn from the water reservoir 2, 10 is a carbon dioxide gas cylinder, 11 is a syrup line drawn from the BIB 1 and piped to the bend stage 6, and 12 is inserted in the middle of the syrup line 10. Cooling coil immersed in the water of the cooling water tank 4
This is a syrup pump (positive displacement pump) that sucks syrup from B1 and sends it. Here, BIB1 is a BI-type in which a plug-type joint provided at the tip of a tube drawn from the bag is attached to the hose end of syrup line 11.
It is connected to the B connector 14. In addition, BI
The B connector 14 incorporates a valve mechanism that opens and closes in response to the attachment and detachment of the BIB1, and the mouth is closed when the BIB1 is removed. Above the bend stage 6, carbonated water nozzles and cold water nozzles are opened toward the cup 13 alongside the syrup nozzles leading to the syrup line 11.

In this configuration, when a syrup beverage sales instruction is given, first, the cup 15 is carried out to the bend stage 6 from the cup supply mechanism 7. At the same time, the syrup pump 13 and the cold water supply pump 8 are started, and the syrup sucked from the BIB 1 and the dilution water supplied from the water reservoir 2 are supplied to the bend stage 6 through the cooling coil through the cooling coil. The carbonated water valve is opened and a fixed amount of carbonated water extracted from the carbonator 3 is supplied to the cup 13 while the carbonated water valve is opened.
And mix in the cup. Further, chip ice is put into a cup 15 from an ice maker (not shown) to finish a cold beverage.

[0004]

The above-mentioned cup-type vending machine is designed to periodically clean the beverage system in the machine from the viewpoint of hygiene management. Particularly, for the syrup line 11, the washing water is supplied from another line. Alternatively, washing is performed by flowing carbonated water through a syrup line, and the washing waste liquid is discharged from a syrup nozzle to a bend stage 6 and guided to a drain bucket 16 to be collected.

In this case, a pressure vending cup vending machine in which syrup contained in a syrup container serving as a pressure vessel is pressure-fed by a carbon dioxide gas pressure supplied from a carbon dioxide gas cylinder in place of the above-mentioned BIB,
The hose on the OUT side connected to the syrup container is connected to the branch joint of the carbonated water supply line leading to the carbonator, and the carbonated water produced by the carbonator (water pressure 5 kg / c)
m ² ) to the syrup line for washing.

On the other hand, a syrup-containing BIB 1 is connected as shown in FIG.
In the syrup line 11 for feeding the syrup sucked from the syrup, the syrup pump 13 and the BIB connector 1
The hose on the suction side, which is connected between the pump 4 and the pump 4, has a piping structure adapted to the suction pressure (negative pressure) of the pump. Because this connection is not as strong as the pressure rise method,
If carbonated water is supplied under pressure to the syrup line as in the pressure rise method described above, problems such as liquid leakage from the hose connection portion and hose detachment may occur if the conventional structure is used.

Therefore, conventionally, as shown in FIG. 5, during cleaning, the BIB connector 14 of the syrup line 11
After removing IB1, wash water container 17 prepared separately
And the washing water 18 is connected to the BIB connector 14 by a washing hose 18, and in this state, the syrup pump 13 is operated to supply the washing water drawn from the washing water container 17 to the syrup line 11 from the BIB connector 14. Like that.

ag In Box) via a connector, a syrup pump, a syrup line plumbed to the bend stage via a cooling coil, and a water reservoir for storing tap water from the water pump to the bend stage via a cooling coil. Equipped with a chilled water line piped between them, BI
In the cup-type vending machine in which the syrup extracted from B and the water stored in the water reservoir are spouted and supplied to the cup, the washing water hose is connected to the inlet side of the syrup line, and the syrup pump is operated in this state. Accordingly, the stored water in the water reservoir is supplied to the syrup line through the cleaning water hose to perform the cleaning (claim 1).

The water reservoir installed in the cup-type vending machine stores clean water (sterilized) supplied from water by opening the reservoir container to the atmospheric pressure. The syrup from the water reservoir to the syrup line through the washing hose by the suction operation of the syrup pump, without imposing undue pressure on the suction side hose of the syrup line and saving the trouble of preparing a separate washing water container as in the past. And the syrup line can be sanitarily washed with clean washing water. In addition, the present invention can easily cope with existing cup-type vending machines deployed at various locations simply by adding a three-way cock and a washing water hose.

According to the present invention, a three-way cock is inserted into a pipe upstream of a water supply pump of a chilled water line connected to a water reservoir as a cleaning circuit used for performing the above-described cleaning method. The washing water hose is drawn out from the branch port and connected to the pipe (claim 2), and the connection between the washing water hose and the syrup line can be specifically implemented in the following manner.

(1) A hose joint for connecting to the BIB connector of the syrup line is provided at the end of the washing hose, and the BIB is detached at the time of washing, and the hose joint is connected to the BIB connector to wash the washing water into the syrup line. (Claim 3). (3) A three-way joint is interposed in the pipeline between the BIB connector connected to the end of the syrup line and the syrup pump. At the time of washing, the tip of the washing hose drawn from the cold water line side is connected to the branch port of the three-way joint. Then, the washing water is supplied to the syrup line (claim 4).

(4) BI connected to syrup line terminal
A branch joint for connecting a washing water hose is provided on the B connector, and at the time of washing, a tip of a washing water hose is connected to the branch joint to supply washing water to the syrup line (claim 5).
