PROCESS FOR PRODUCING HYDROGEN-CONTAINING WATER FOR DRINKING
First Claim
1. A process for continuously producing hydrogen-containing water for drinking, characterized by comprising:
- (a) a purifying step of filtering and purifying water as a raw material in a purification device and transferring the purified water obtained to a degasser;
(b) a degassing step of degassing the purified water supplied to the degasser and transferring the degassed water obtained to a hydrogen dissolution device;
(c) a hydrogen-dissolving step of dissolving hydrogen gas in the degassed water supplied to the hydrogen dissolution device and transferring the hydrogen-dissolved water obtained to a sterilizer;
(d) a sterilizing step of sterilizing the hydrogen-dissolved water supplied to the sterilizer and transferring the hydrogen-containing water obtained to a filling device;
(e) a filling step of filling the hydrogen-containing water supplied to the filling device in a sealed container and transferring the filled water product to a heat sterilizer; and
(f) a heat-sterilizing step of heat-sterilizing the water product supplied to the heat sterilizer, whereinthe hydrogen dissolution device is partitioned into a water room and a gas room by a gas permeable membrane and includes a gas permeable membrane module that dissolves hydrogen gas in the degassed water by allowing the degassed water to pass through the water room and by pressurizing the hydrogen gas and supplying the pressurized hydrogen gas into the gas room, and part of the hydrogen-containing water obtained in the step (d) is returned to the degasser in the step (b) and the water is circulated through the steps (b) to (d).

Abstract
There is provided a process for producing hydrogen-containing water for drinking, by which the dissolved hydrogen concentration of the obtained hydrogen water can be more efficiently increased. A process for continuously producing hydrogen-containing water for drinking, comprising (a) a purifying step of filtering and purifying water as a raw material; (b) a degassing step of degassing the purified water supplied to a degasser; (c) a hydrogen-dissolving step of dissolving hydrogen gas in the degassed water supplied to a hydrogen dissolution device; (d) a sterilizing step of sterilizing the hydrogen-dissolved water supplied to a sterilizer; (e) a filling step of filling the hydrogen-containing water supplied to a filling device in a sealed container and transferring the filled water product to a heat sterilizer; and (f) a heat-sterilizing step of heat-sterilizing the water product supplied to the heat sterilizer, wherein part of the hydrogen-containing water obtained in the step (d) is returned to the degasser in the step (b) and the water is circulated through the steps (b) to (d).
