AGITATING BLADE, AGITATING DEVICE, BEVERAGE MANUFACTURING DEVICE AND AGITATING PART Russian patent published in 2018 - IPC A47J31/44 

FIELD: agitation.

SUBSTANCE: agitating blade member for stirring the fluid comprises a rotating part having a central rotation axis; a plurality of blade parts provided on the side of the first surface of the rotating part, a plurality of blade surfaces provided on the side of the second surface opposite to the first surface of the rotating part. In this case, the plurality of blade parts is configured such that they surround the central rotation axis and are rotationally symmetrical about the rotation centre of said rotation axis. In this case, the plurality of blade surfaces extends radially from the outer circumferential surface of the rotation axis. Plurality of blade parts and the plurality of blade surfaces differ in shape from each other. Number of blade surfaces is smaller than the number of blade parts. Plurality of blade parts and the plurality of blade surfaces do not overlap each other in the vertical direction. Beverage preparation apparatus comprises a grinding machine for producing powders by grinding an object to be grinded, abraded; a tank for liquid retaining; a heating part that provides liquid heating in the tank and liquid supply; and an agitating device into which powders and liquid are fed. Agitating device comprises an agitating blade; an agitating tank in which the agitating blade is disposed; and a drive mechanism for rotating the agitating blade. In this case, the mechanism of contactless transmission of rotation, which provides a non-contact transmission of the rotating force, which is created by the drive mechanism, the agitating blade, is provided between the agitating blade and the drive mechanism.

EFFECT: invention relates to the agitating blade, the agitating device, the beverage manufacturing device.
