  • the productivity is poor, and a large-scale manufacturing apparatus is required to produce a large amount of hydrogen-containing water.
  • hydrogen cannot be efficiently dissolved in the raw water, resulting in a problem that not only the consumption of hydrogen increases but also the hydrogen concentration tends to vary from lot to lot. This is because when hydrogen-containing water is produced in a batch mode, when the hydrogen-containing water is extracted from the pressurized tank and filled in a highly airtight container and sealed, dissolved hydrogen can easily escape, This is because oxygen (or air) was easily mixed.
  • the fluid pressure is greatly reduced by Bernoulli's theorem during extraction and filling. That is, when extracting the dissolved hydrogen water from a pressure vessel such as a pressurized tank, the dissolved hydrogen water is usually extracted through a pipe-shaped extraction pipe having a diameter much smaller than the tank diameter of the pressurized tank. Therefore, according to Bernoulli's theorem, which will be described later, the pressure applied to the dissolved hydrogen water as a fluid is greatly reduced as compared with that in the pressurized tank.
  • dissolved hydrogen can easily escape during extraction and filling, and another major factor that can easily cause oxygen (or air) in the filling atmosphere to enter is the pressure in pressurized tanks, etc.

So-called negative feedback control is performed to control the dissolution pressure.
  • the dissolved hydrogen concentration in the hydrogen-containing water is measured online after sterilization in the sterilization section and immediately before filling the container.
