PROPELLER MIXER FOR STIRRING OF LIQUID MEDIUMS Russian patent published in 2005 - IPC

FIELD: food industry; chemical industry; bio-industry and other industries; production of machines and apparatuses for liquid mediums mixing.

SUBSTANCE: the invention is pertaining to production of machines and apparatuses for liquid mediums mixing with the help of the mechanical propeller mixers and may be used in food, chemical, biological and other industries. The purpose of the invention is to increase a mass transfer along the axes of spinning of the mixer and to intensify the process of stirring. Such a technical task is achieved by the fact, that the end edge of each lobe is bent to the side of the effective surface by an angle β laying in the interval from 85° up to 175°, and the height of the bent edge in respect to the effective surface makes from 1 up to 15 % from the diameter size value and the radius of the smooth transfer between the effective surface of the lobe and the effective surface of an end edge makes 1/3 - 1/15 part of a lobe radius.

EFFECT: the invention ensures increased mass transfer along the axes of spinning of the mixer and intensification of the process of stirring.
