Description of the Related Art The inventor of the present invention efficiently and excellently extracts an animal / vegetable extract raw material such as coffee, tea, hops, shavings and mannedake with carbonated water as described in Japanese Patent Application No. 59-241437. He discovered that an extract could be obtained and applied for a patent.
しかし、この炭酸水による抽出は、抽出原料を入れた抽
出塔の一端から炭酸水を入れ、他端から抽出液が出るよ
うになった抽出装置で行っている。However, this extraction with carbonated water is carried out by an extraction apparatus in which carbonated water is introduced from one end of the extraction tower containing the extraction raw material and the extraction liquid comes out from the other end.

が不可能となることさえある。Problems to be Solved by the Invention In this conventional method, it is necessary to apply pressure to the carbonated water sent to the extraction tower so that the carbon dioxide gas of the carbonated water does not gasify and escape. On the other hand, at the outlet of the extraction tower, the pressure decreases to atmospheric pressure, so that the carbon dioxide gas in the extraction liquid is gasified near the outlet of the extraction tower to become a gas in the extraction liquid. Therefore,
The extraction liquid that comes out from the outlet comes out with gas, so when the gas comes out, the pressure inside the extraction tower drops, and when the liquid comes out, the pressure rises, a so-called knocking phenomenon is seen, and the pressure constantly and suddenly increases. Change. As a result, the extraction raw material is knocked and tightened in the extraction tower, and clogging occurs. Therefore, the flow of the extraction liquid becomes poor, the extraction takes time, and sometimes the extraction liquid does not flow and extraction may become impossible.
しかも、抽出塔の出口付近でガス化した炭酸ガスは、気
泡となり、抽出液の流れを一層悪くした。Moreover, the carbon dioxide gas gasified in the vicinity of the outlet of the extraction tower became bubbles, further impairing the flow of the extraction liquid.

まり目詰まりを起こすのを防ぐことができた。Means for solving the problem An apparatus in which an extraction raw material such as coffee is put in an extraction tower, an aqueous liquid containing pressurized carbon dioxide gas is injected from one end of the extraction tower, and the extraction liquid is taken out from the other end. When extracting with, the pressure of carbon dioxide gas is applied to the extract at the extract outlet. As a result, it was possible to prevent a rapid change in the pressure in the extraction tower, and to prevent the extraction raw material from being clogged and clogged due to knocking in the extraction tower.

の排出管4aがある。The pressure of carbon dioxide at the outlet of the extraction liquid can be applied by, for example, providing a gas-liquid separator as shown in FIG. 1 next to the outlet of the extraction column. That is, the gas-liquid separator 2a is composed of a container into which the extraction liquid coming out of the extraction tower 1a is allowed to flow, an upper part thereof has an air supply pipe 3a for entering carbon dioxide gas, and a lower part thereof has an extraction function. There is a discharge pipe 4a for discharging the liquid.

の結果、抽出塔の中で抽出原料が手締まり目詰まりする
のが防げた。This gas-liquid separator is always kept in a state of being pressurized to a constant pressure by the carbon dioxide gas sent from the air feeding pipe. Since the extract liquid entered from the extraction tower is accumulated in the lower part of the gas-liquid separator, the amount of the extract liquid discharged from the discharge pipe is adjusted so that only the liquid is discharged. As a result, it was possible to prevent the gas from being discharged at the same time as the extraction liquid was discharged and the pressure to suddenly drop, and to prevent knocking caused by a sudden change in pressure. As a result, it was possible to prevent the extraction raw material from being clogged by hand in the extraction tower.
なお、気液分離器に加える圧力は、抽出塔内を抽出液が
流れるように抽出塔入口の圧力よりいくらか低くする必
要がある。The pressure applied to the gas-liquid separator needs to be somewhat lower than the pressure at the inlet of the extraction column so that the extraction liquid flows in the extraction column.
