An apparatus for producing hydrogen water, comprising:
- a purification and sterilization part for purifying and sterilizing water for producing hydrogen water;
- a hydrogen water forming part for providing hydrogen gas to the water having been purified and sterilized in the purification and sterilization part so as to form hydrogen water;
- a hydrogen water packaging part for packaging the hydrogen water having been formed in the hydrogen water forming part into a hydrogen water container;
- a hydrogen blower for blowing and injecting hydrogen gas into the hydrogen water container having gone through the hydrogen water packaging part to a saturated state;
- and
- a seaming part for sealing the hydrogen water container after the hydrogen blower blows hydrogen gas so as to prevent the hydrogen gas from leaking, wherein:
- the apparatus for producing hydrogen water, further comprises a timing sensor for sensing the timing of blowing hydrogen gas by the hydrogen blower, and
- a liquid nitrogen insertion part for inserting liquid nitrogen into the hydrogen water container in accordance with the timing of blowing hydrogen gas, sensed by the timing sensor, so as to prevent hydrogen dissolved in the hydrogen water container from being eluted and to remove dissolved oxygen at the head space of the hydrogen water container.
