CENTRIFUGAL MIXER Russian patent published in 2005 - IPC

FIELD: food and chemical and other industries.

SUBSTANCE: the invention concerns to devices for continuous preparation of mixtures of loose materials and may be used in food, chemical and other industries. The centrifugal mixer of loose materials contains a vertical cylindrical body, a cover on which there is a feeder with loading branch-pipes, a driving shaft with fixed on it unloading blades and a rotor made in the form of a disk with the fixed to it and concentrically located hollow truncated cones, at which the height and angle of inclination of the generatrix to the base are increasing from the central part to the periphery. On the effective surfaces of the internal and middle cones there are windows, which from below are limited by a surface of the disk. On the internal surfaces of the middle and external cones there are the guiding blades installed as in the form of a spiral and having a number of apertures and a profile of an arc of a circle. Due to that it provides a significant rarefication of the advancing flows, a contour of the reverse recirculation of the flows of the materials is forming, a number of dead zones in different parts of the rotor decreases, additional turbulization to the mixed components that promotes the best interpenetration of particles.

EFFECT: the invention ensures intensification of mixing process, rarefication of advancing flows, decrease of the number of the dead zones in the different parts of the rotor, additional turbulization of mixed components.
