Abstract
An ultrafine bubble-containing liquid producing apparatus and method enables preventing ultrafine bubbles over a long period of operation by, based on a predetermined condition, switching between a first mode where a liquid between an ultrafine bubble generating unit and a storing chamber is circulated at a first flow velocity and a second mode where the liquid is circulated at a second flow velocity higher than the first flow velocity.
Claims17
An ultrafine bubble-containing liquid producing apparatus comprising:
- an ultrafine bubble generating unit configured to generate ultrafine bubbles inside a liquid;
- a circulating unit configured to circulate the liquid through a circulation path including the ultrafine bubble generating unit;
- and
- a control unit configured to control the ultrafine bubble generating unit and the circulating unit,
- wherein the control unit, based on a predetermined condition, switches between a first mode where the liquid in the circulation path is circulated at a first flow velocity and a second mode where the liquid in the circulation path is circulated at a second flow velocity higher than the first flow velocity.
