There are provided a method and apparatus for manufacturing hydrogen-containing drinking water that can fill a packaging container with hydrogen-containing water while suppressing the change of the dissolved hydrogen concentration of the hydrogen-containing water to a low level.;A method of continuously manufacturing hydrogen-containing drinking water includes (A) a deaeration step, (B) a hydrogen dissolving step, (C) a filling step, and (D) a sealing step. Pressure is applied to water flow channels corresponding to hydrogen-containing water, which is to be injected to a packaging container in the filling step, from purified water that is to be supplied to the deaeration step. The filling step includes: a preparation stage of supplying hydrogen-containing water, to which pressure is applied, into a filling device; a deaeration stage of removing gas, which is present in the packaging container, after connecting the packaging container to the filling device; an injection stage of directly injecting the hydrogen-containing water, to which pressure is applied, into the packaging container; and a discharge stage of discharging hydrogen-containing water, which remains in the filling device, into the packaging container by introducing pressurized air into the filling device. The method further includes a step of immediately proceeding to the sealing step (D) when the injection port and the filling port are disconnected from each other. |

1. An apparatus for continuously manufacturing hydrogen-containing drinking water, the apparatus comprising:
(a) a deaeration device that deaerates purified water of a supplied raw material through a hollow fiber membrane; (b) a hydrogen dissolution device that dissolves pressurized hydrogen gas in deaerated water, which is supplied from the deaeration device, through the hollow fiber membrane; (c) a filling device that fills a packaging container with a spout from an injection port of the packaging container with hydrogen-containing water supplied from the hydrogen dissolution device; (d) a sealing device that seals the injection port of the packaging container with a spout completely filled with the hydrogen-containing water; a pressure pump that is capable of applying pressure to water flow channels corresponding to the hydrogen-containing water, which is to be injected to the packaging container by the filling device (c), from the purified water that is to be supplied to the deaeration device (a); a relief valve that is connected to a loop flow channel allowing the water flow channel, to which pressure has been applied by the pressure pump, to communicate with the water flow channel to which pressure is not yet applied, closes the loop flow channel when water pressure of the water flow channel to which pressure has been applied is lower than a certain reference pressure, and opens the loop flow channel when the water pressure exceeds the certain reference pressure; and an orifice that is connected to the water flow channel provided ahead of the filling device (c) and limits the flow rate of hydrogen-containing water, to which the reference pressure is applied and which is to be supplied to the filling device (c), to a certain reference flow rate or less, wherein the filling device (c) includes a cavity that is formed in a device body and is connected to a filling port, and includes a stem valve that is capable of reciprocating so that a tip portion of the stem valve faces the filling port, the cavity communicates with the water flow channel extending from the hydrogen dissolution device (b), the stem valve is a valve mechanism that allows the injection port of the packaging container, which is connected to the filling port, to communicate with the water flow channel extending from the hydrogen dissolution device (b) and blocks the communication of the injection port by the reciprocation thereof, the cavity is connected to gas decompression means and gas pressurization means through a gas channel that is formed in the stem valve or formed along an outer surface of the stem valve, and the gas channel is adapted to be opened and closed by the reciprocation of the stem valve. |
