Abstract
A kneading device for dispersing a dispersoid in a dispersion medium includes a casing in which a kneading material containing the dispersion medium and the dispersoid is accommodated, a rotor disposed in the casing and kneading the kneading material while dispersing the dispersoid in the dispersion medium by rotating about a rotation axis, and a detection unit detecting a dispersion degree of the dispersoid in the dispersion medium by observing a state of the kneading material in the casing.
Claims20
A kneading device comprising:
- a casing configured to:
- accommodate, within the casing during a kneading operation, a kneading material that contains a dispersion medium and a dispersoid;
- a rotor configured to:
- knead the kneading material while dispersing the dispersoid in the dispersion medium by rotating about a rotation axis;
- and
- a detection unit configured to:
- capture, during the kneading operation, an image of the kneading material,
- detect, in the image, a quantity of protrusions on a surface of the kneading material, the protrusions being formed by the dispersoid, and
- determine, from the detected quantity of protrusions, a dispersion degree of the dispersoid in the dispersion medium,
- wherein the rotor is disposed in the casing.
