Abstract
A colloid mill for reducing a particle size of particles having a rotor and a stator, which are arranged coaxially one inside the other. The colloid mill has a material inlet for introducing a suspension or emulsion on a first axial side and a product outlet for conducting away the suspension or emulsion on a second axial side. The rotor has a rotor grinding surface, and/or the stator has a stator grinding surface. The rotor grinding surface has a grinding tooth with a shearing surface and/or shearing edge, the cross-sectional surface of which grinding tooth tapers, in a plane perpendicular to the axis of rotation, wherein the cross-sectional surface has a first leg, which adjoins a base side and encloses an angle with the base side.
Claims12
A colloid mill for reducing a particle size of particles suspended in a first liquid, and/or a droplet size of a second liquid emulsified in a first liquid, wherein the first liquid is in particular a fat-based mass,
- having at least one rotor and at least one stator, which are arranged coaxially one inside the other, wherein the rotor is preferably arranged or can be attached within the stator,
- wherein the colloid mill preferably has at least one material inlet for introducing particles, a liquid, a suspension and/or emulsion on a first axial side and at least one product outlet for conducting away the suspension or emulsion on a second axial side,
- wherein the at least one rotor has a rotor grinding surface facing or to be faced toward the stator, and/or the at least one stator has a stator grinding surface facing or to be faced toward the rotor,
- wherein
- the rotor grinding surface has at least one grinding tooth with a shearing surface and/or shearing edge, wherein the cross-sectional surface of the grinding tooth tapers, in a plane perpendicular to the axis of rotation, in the radial direction toward the opposite stator grinding surface, wherein the cross-sectional surface has a first leg, preferably a straight first leg, which adjoins a base side, running in the circumferential direction, of the cross-sectional surface, points in the direction of rotation of the rotor, encloses an angle of 80°-100°, preferably 85°-95°, with the base side and is preferably located on a radial line through the axis of rotation,
- and/or
- the stator grinding surface has at least one grinding tooth with a shearing surface and/or shearing edge, the cross-sectional surface of which grinding tooth tapers, in a plane perpendicular to the axis of rotation, in the radial direction toward the oppositerotor grinding surface, wherein the cross-sectional surface has a second leg, preferably a straight second leg, which adjoins a base side, running in the circumferential direction, of the cross-sectional surface, wherein the second leg points counter to the direction of rotation of the rotor, and the second leg encloses an angle of 80°-100°, preferably 85°-95°, with the base side and is preferably located on a radial line through the axis of rotation.
