10 rowsThe primary function of the stirrer shaft is to transmit torque from the stirrer motor to the impeller. Torque is the tendency of a force to cause an object to rotate. The …
A liquid height to tank diameter H/D > 1 should be chosen to reduce the overall impact of the shear due to bubble bursts at the surface. A high-power motor with variable speed should be used to keep the oxygen transfer rate above the oxygen uptake rate, even with changing rheology of the broth.
The Stirred Tank: Mixing Time and Power Requirement When using a rotating impeller to mix fluids contained in a tank, we ask two questions: • What size motor do we need for …
The aim of this paper is to study the effect of agitator's types on the turbulent flows in stirred tanks without and with baffles. The hydrodynamics behavior induced by four different agitator's types: a Rushton turbine (RT), a circular blade turbine (CBT), a diverging triangular blade turbine (DTBT) and converging triangular blade turbine (CTBT) are …
The continuous stirred tank reactor is sometimes named a BMR or back-mixed flow reactor. Similar to a batch reactor, an agitator is intentionally added in a continuous stirred-tank reactor to fully disperse the reactants into a reaction compound immediately after they enter the tank. The product flow is continuously drawn off from the …

Tri-clamp mixers are engineered to mount quickly and securely to a tri-clamp fitting, commonly found on a variety of processing tanks and vessels. These tri-clamp mixers were designed to be easily cleaned, and have outstanding durability and lightweight portability. Our standard line of tri-clamp mixers are available w
No matter the scale, stirred tank bioreactors are the most commonly used systems in biotechnological production processes. Single-use and reusable systems are supplied by several manufacturers. The type, size, and number of impellers used in these systems have a significant influence on the characteristics and designs of bioreactors. …
A 1 hp stirring motor is supplied to a tank containing 22.7 kg of air. The stirring action is. applied for 2 hours and the tank losses 850 kJ/hr of heat. Calculate (a) the paddle work in. kJ, (b) change of internal in kJ, and (c) the change in temperature of air after 2 hours, assuming that the process occurs at constant volume.
Mixing is the operation by which a system evolves under stirring from one state of simplicity—the initial segregation of the constituents—to another state of simplicity—their complete uniformity. Between these extremes, patterns emerge, possibly interact, and die sooner or later. This review summarizes recent developments on the problem of mixing …

I have done my mash stirrer using a wiper motor: it works great for making beer ;) By the way I done a mistake with the first stirrer: I mixed aluminium and stainless steel to make it: it makes a big chemical react that dissolves the aluminium. When I washed it using dish-washing liquid the pot diameter lost at least 0.2 mm, and the water was gray.
Power = Np * n3 * d5 * sg * K. The value of the dimensionless power number (Np) depends on several factors including impeller design, number of impellers and location within a tank, tank baffling and fluid viscosity. Typically the power number is shown for mixing in fully turbulent flow.
As you add more ingredients into the stirred tank, the stirrer will proceed with the stirring process. It will stir all the ingredients accordingly at a speed which you will dictate from the control panel. During the mixing process the sensors and monitors within the tanks will communicate the temperature ratings.
A 1-hp stirring motor is applied to a tank containing 22.7 kg of water. The stirring action is applied for 1 hour and the tank losses 850 kJ/h of heat.
