  • Stirring device and stirring method
    Patent number: 9675948
    Abstract: When a first electromagnetic valve of a first stirring tank is turned ON and a second electromagnetic valve of a second stirring tank is turned OFF, the air pressure inside the first stirring tank increases and the liquid in the first stirring tank is sent into the second stirring tank via piping. When the volume of the liquid inside the second stirring tank reaches an upper limit, the first electromagnetic valve of the first stirring tank is turned OFF and the second electromagnetic valve of the second stirring tank is turned ON. As a result, the liquid inside the second stirring tank is now sent into the first stirring tank via the piping. Ultimately, because the liquid is circulated between the first and second stirring tanks and the liquid is flowing at all times due to the repetition of said actions, separation does not occur.
