Present invention creatively makes convenient for any person using beverage to blend powder with liquid uniformly without use of shaking motion or battery and thereby preventing from spilling and running out batteries. Invention of unique reverse planetary gears system and side arm stirrer with window paddle has made possible convert torque of finger to multiple rotation of stirrer in order achieve efficient uniform blending. Moreover, this invention takes full advantage of removable snap mechanism to assemble and disassemble protein blender cup which is very necessary for washing every single parts to achieve highest sanitization. In short, this invention helps consumer to have protein blender cup which doesn't require shaking or battery and can be completely sanitized without any struggle.

An electric stirrer and charging base, wherein electric stirrer comprises a stirrer body and a stirring component, the stirring component is provided at the bottom end of stirrer body, and a supporting part is provided on the bottom of stirrer body; the charging base comprises a charging base body. A bearing part is provided in charging base body, and the stirrer body is supported on bearing part of charging base body through the supporting part, so that stirring component is located below stirrer body and suspended. While avoiding the risk of any liquid flowing into stirrer body to damage the internal circuitry or motor, the technical solution of the present invention prevents the stirring component from contacting any other item to avoid the contamination risk of stirring component. In addition, stirrer body can be placed, charged and taken for use conveniently, and in a normal gesture without any excess motion.

An agitator includes: an agitation tank that accommodates a fluid to be processed containing particles; a flow blade that agitates the fluid to be processed accommodated in the agitation tank; and a shear blade disposed inside the flow blade at a bottom of the agitation tank to disperse the particles. The shear blade 16 includes a base portion rotating around a predetermined axis and a plurality of blades provided at an edge of the base portion. An angle formed on a downstream side in a rotation direction of the base portion between the blade and a tangent line to an outer periphery of the base portion and each of the blades is 15 degrees or more and 60 degrees or less.

A stirring blade includes a first member having a first flat surface and a second member having a second flat surface, wherein the stirring blade is rotatable about a rotational axis in a state where the first and second flat surfaces are opposed to each other and spaced by a first distance across the rotational axis. When the stirring blade is rotated about the rotational axis with the first and second flat surfaces at least partially immersed in an object to be stirred, the object to be stirred having entered between the first and second flat surfaces is discharged in a direction away from the rotational axis by a centrifugal force and, simultaneously, the object to be stirred is sucked into and between the first and second flat surfaces from a direction along the rotational axis.

A stirring paddle for isothermal titration calorimetry includes a blade secured to one end of a shaft. The blade has an edge and a pair of opposing surfaces. A lip extends from the edge and forms a non-zero angle with respect to the opposing surfaces. In some embodiments, the blade has a twisted rectangular shape defined by a pair of first opposing edges and a pair of second opposing edges. One of the first opposing edges is oriented at a rotation angle with respect to the shaft axis that is different than an orientation of the other first opposing edge with respect to the shaft axis. Advantageously, the stirring paddle achieves improved turbulent mixing of injections into liquid within a sample cell, resulting in shorter measurement times. The improved mixing efficiency allows the stirring paddle to be operated at a lower rotation rate.

A mixer (1) comprises a drum (2) having at least one inlet (6) and one outlet (7). The mixer (1) furthermore comprises a drive (3) and a stirring shaft (4), which is arranged in the drum (2) and is coupled to the drive (3). Furthermore, the mixer (1) comprises a conveying device (5), which is arranged in the drum (2) and which is arranged on one and the same axis as the stirring shaft (4).

The invention relates to a process of manufacturing a dental milling block with a homogeneous color and/or translucency gradient. This process comprises the steps of providing a mold with a cavity having a z-direction and an x/y-direction, filling the cavity partially with a first powder up to a height H1, the first powder having a volume VP1 with a top and bottom surface, introducing a second powder on top of the first powder up to a height H2, the second powder having a volume VP2 with a top and bottom surface and, the top surface of the first powder being in contact with the bottom surface of the second powder and forming an intermediate region, providing a mixer unit with at least one rotatable mixing element, introducing the rotating mixing element in z-direction into the intermediate region, mixing the powder located in the intermediate region by rotating the mixing element, removing the rotating mixing element from the powder, compacting the powder, optionally applying heat to the compacted powder, the first powder differing from the second powder by its physical properties and/or chemical composition and/or color. The invention also relates to a process of producing a dental restoration using dental milling block obtainable according to this process.

A mixer includes a drum having at least one inlet and one outlet. The mixer furthermore includes a drive and a stirring shaft, which is arranged in the drum and is coupled to the drive. Furthermore, the mixer includes a conveying device, which is arranged in the drum and which is arranged on one and the same axis as the stirring shaft.

A device for circulating wastewater is received in a tank, in which a conical or hyperboloid-like stirring body is mounted on a vertical stirring shaft, wherein the stirring body is composed from a plurality of segments produced from metal along radially extending joining zones.
