Abstract
A method, for controlling a mixer that mixes materials through rotation of an impeller while a solvent contained in the materials is evaporated under negative pressure, performs a process in which the mixer is operated while the pressure inside the mixer is increased or decreased according to a predetermined profile. When a power value of the impeller exceeds a predetermined upper limit during the operation of the mixer, the pressure inside the mixer is increased. When the power value falls below a predetermined lower limit during the operation of the mixer, the pressure inside the mixer is decreased.
Claims8
A method for controlling a mixer, the method comprising:
- mixing materials comprising magnetic particles and a solution comprising a resin and a solvent, through rotation of an impeller while the solvent is evaporated under negative pressure, to thereby produce a carrier for electrostatic image development,
- wherein the mixing comprises performing a process comprising operating the mixer while a pressure inside the mixer is increased or decreased according to a predetermined profile,
- wherein, when a power value of the impeller exceeds a predetermined upper limit during the operation of the mixer, the pressure inside the mixer is increased, and
- wherein, when the power value falls below a predetermined lower limit during the operation of the mixer, the pressure inside the mixer is decreased.
