A mixing method, a controller and a mixing device for mixing components in a mixing vessel are provided. The mixing method includes providing a mixing impeller in the mixing vessel; accelerating the mixing impeller from an inactive state to a rotating state in which the mixing impeller rotates at a first desired speed in a first rotation direction; rotating the mixing impeller at the first desired speed for a first time t.sub.steady,1 in the first rotation direction; changing the rotation direction of the mixing impeller, so that the mixing impeller rotates in a second rotation direction at a second desired speed; and rotating the mixing impeller at the second desired speed for a second time t.sub.steady,2.

A method is provided for monitoring a flow behavior of mixed components without requiring additional instrumentation or sampling. The method is carried out by determining ratios of the power required to rotate a mixing impeller at different rotational speeds and then comparing the ratios. Characteristics about the mixed components are determined based on differences between the ratios.

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.

Viscosity and other properties are determined at desired temperatures in drilling mud and other fluids by using a versatile cavitation device which, operating in the cavitation mode, mixes and heats the fluid to a specified temperature, and, operating in the shear mode, acts as a spindle for application of Couette principles to determine viscosity as a function of shear stress and shear rate. The invention obviates the practice of adjusting rheology of a drilling fluid by passing it through the drill bit. Drilling fluid may be managed by a “straight-through” method to the well, or by placing the cavitation device in a loop which isolates an aliquot of known volume and circulating the fluid through the loop including the cavitation device. A controller may be programmed to manage the viscosity and other properties at various temperatures by controlling the power input and angular rotation of the “spindle” (which has cavities on its cylindrical surface), and feeding viscosity-adjusting agents and other additives to the fluid. Data may be collected from the loop and used in the “straight-through” mode until it is determined that conditions require a new set of data, or the loop may be used continuously. The system may be used with a supplemental viscometer, density meter, and other instruments.
