Production apparatus for a liquid containing gas bubbles and production system for a liquid containing gas bubbles

A production system for a liquid containing gas bubbles, comprising:

• a tank that reserves a liquid;
• and
• a production apparatus for a liquid containing gas bubbles, which is placed inside the tank and includes
• a casing including an inlet and an outlet,
• a shearing mechanism unit that is provided between the inlet and the outlet and applies shearing force to a liquid flowing to the shearing mechanism unit from the inlet,
• a gas injection unit that is connected to the inlet and injects a gas into a liquid introduced into the inlet, and
• a pump unit that is attached to the shearing mechanism unit and transports a liquid to the outlet from the inlet by driving of a motor,
• wherein
• the shearing mechanism unit includes
• a rotor that includes a rotary shaft and a tube portion and is rotatably disposed inside the casing, the tube portion having an outer peripheral portion including a first structure surface in which a plurality of dimples is formed circumferentially and axially,
• a motor that is provided in the rotary shaft and applies rotating force around the rotary shaft to the rotor and the pump unit, and
• a tubular facing member that has an inner peripheral portion and is provided in an inner wall portion of the casing, the inner peripheral portion facing the first structure surface via a predetermined clearance.
