Regarding coffee liquid extraction, various methods have already been proposed. The basic idea is to connect multiple extraction towers in a series, and sequentially pass hot water as a solvent through each of the extraction towers filled with coffee raw materials (beans), until the final extraction tower is completed. A coffee liquid of a predetermined concentration is recovered from the coffee. Therefore, in order to increase the amount of extracted coffee liquid, it is only necessary to increase the flow rate of the extract flowing sequentially in each extraction column. In this case, the extraction tower into which hot water is first injected among the multiple extraction towers extracts the largest amount from coffee beans due to osmotic pressure.
It gradually becomes smaller. This is because the coffee concentration of the solvent passing through each extraction column for extraction increases. Therefore, when focusing on the coffee raw materials (beans) in each extraction tower, the coffee beans in the first extraction tower are the most worn out, and the coffee beans in the last extraction tower are the least worn out. Therefore, the concentration of the extract from the last extraction tower is constantly measured, and if this concentration drops below the standard concentration, the first extraction tower containing hot water, which has the greatest degree of wear and tear, is removed from the extraction series. It is necessary to separate the extraction column and enter the extraction column containing new coffee raw material into the extraction train. However, the extraction tower filled with new coffee raw materials and waiting for the next combination is filled with dry coffee raw materials, and therefore pressure is created between these coffee raw materials. As a result of passing the applied extract liquid, the pressure inside the extraction tower increases, and there is a risk that the extraction tower will burst.

No. 1246276 (Special Publication No. 59-20335) was proposed. An outline of the above proposal will be explained using FIG. 6. Figure 6 shows how multiple extraction towers are connected and in operation, and how a worn-out extraction tower is separated and a new extraction tower filled with coffee raw materials enters the extraction line. It is a list diagram showing what to do.

いる。 More specifically, the top stage is an extraction tower.
For example, among the six groups of , , ,
When extracting coffee liquid using four units, if the coffee raw materials in the extraction tower are worn out and become unusable, the unusable extraction tower is removed from the extraction series and a new one is installed. This shows the case where an extraction tower filled with coffee raw materials is added to a new extraction series. Therefore, the extraction tower shown at the top of the column represents the newly entered extraction tower, and the extraction tower shown in the horizontal row...

ためである。 In this case, the next extraction series will be carried out using four units, so the extraction column should be connected immediately (the extraction column has already been subjected to swelling), but it is necessary to connect the extraction column immediately (physically adjacent). not,
A series of extractions can be performed on an extraction tower that has been filled with new coffee raw materials in advance (an extraction tower that is next in the order of the adjacent extraction tower) without immediately connecting the extraction tower (adjacent in the order of extraction operations). Inject the coffee concentration solution that has gone through the process until it overflows, and after the coffee concentration solution has been sufficiently injected, connect the extraction column that should originally be connected,
Perform an extraction operation using the new extraction sequence, , . This is because the extraction tower is already in a swollen state, and during the extraction operation by the extraction tower, the extraction tower that has already been injected with the coffee concentration solution becomes sufficiently swollen. .

That is, using the pump 8, hot water as a solvent from the hot water tank 7 is passed through the injection main pipe 9 in the order of extraction tower→→→, and the extract from the final extraction tower is passed through the discharge pipe 1.
0 to the extract liquid tank 11. In this extraction process, as mentioned above, the coffee beans in the extraction tower into which hot water is first injected are the most severely damaged, so in this case, the extraction tower that is most worn is disconnected, and the adjacent extraction tower that is already on standby is connected. Prior to this, after injecting the coffee concentration solution that has undergone a series of extraction steps into the next extraction tower of the adjacent extraction tower,
Perform the extraction operation with the new extraction sequence, , and then do the same extraction sequence, ,
The extraction operation is repeated by sequentially switching the extraction operation as follows.

みを示しており開閉状態を示したものではない。 At this time, the extraction tower with the greatest loss of coffee raw materials is disconnected, and prior to connecting the adjacent extraction tower that is filled with new coffee raw materials and is in a standby state, the next extraction tower of the adjacent extraction tower is connected. The coffee concentration solution that has undergone a series of extraction processes must be injected into the extraction column. However, there is no way to connect the final extraction column to the extraction column without passing through an adjacent extraction column, and some other means must be used. In addition, in FIG. 7, the valves shown in each pipe are shown only in their positions and not in their open/closed states.

, the inside of the injection main pipe 9 is directed in the direction of the arrow, and it enters the first extraction tower via the inlet pipe 12, and then enters the extraction tower from below the extraction tower via the inlet pipe 12. After that, as the coffee liquid goes through the extraction tower and then the extraction tower in the same way, the concentration of the coffee liquid increases sequentially, and these coffee liquids are stored in the extract liquid tank 11 by the discharge pipe 10 and are then extracted one by one. end. In addition, in order to obtain the above-mentioned flow of the solvent and coffee liquid, the opening and closing states of the valves, for example, in this case, valves 15 to 19 are open, valves 2
0, 22, 24, 27, 30, 32, 34, 3
