What is the difference between a liquid mixing tank and a mixing tank? What is the difference between a liquid mixing tank and a mixing tank? The practice of mixing and mixing liquids: The terms mixing and mixing are sometimes interchangeable
.
Blending refers to the ability to combine each component at a microscopic level, often referred to as micro-blending
.
Mixing describes fluids in motion, but not necessarily mixing (macro mixing)
.
Just like stainless steel mixing tanks and mixing tanks, we need micro mixing (shaking) and macro mixing… What is the difference between a liquid mixing tank and a mixing tank? The practice of mixing and mixing liquids: The terms mixing and mixing are sometimes interchangeable

.
Mixing describes fluids in motion, but not necessarily mixing (macro mixing)
.
Just like stainless steel mixing tanks and mixing tanks, we need micro-mixing (shaking) and macro-mixing (mixing) for a successful entire tank mixing operation! Where to find it? Many designs can be found in upstream, downstream, filling and polishing applications including: Storage: Liquids are held in constant motion to maintain a constant concentration and temperature mixing of two or more different liquids
.
For example, typical low shear biopharmaceuticals are used in storage tanks, buffer tanks and media vessels
.
Heat transfer: In order to achieve a constant temperature of the heated (jacketed) vessel, the liquid needs to be constantly moving
.
Mixing Liquids: The pumping action of the mixer is to mix the liquids together to create a uniform combination in the tank
.
Higher pumping rates will speed up mixing, but may create more shear and create impossible vortices
.
Need to balance mixing time and acceptable shear/vortex
.
Dissolving solids in liquids: Similar to mixing dissolved liquids, pumping helps dissolve and keep ingredients in a liquid state
.
Solids that are difficult to bond often require a higher degree of cutting and vortex-forming capabilities
.
Suspension: The solid is suspended in the liquid phase
.
Usually a low shear mixer is used
.
The transfer power depends on the speed at which the particles settle and the degree of suspension desired (eg, off the bottom or evenly suspended)
.
Dissolving gas in liquid: This is very common in bioreactors where air is introduced
.
A mixer helps disperse air bubbles and increases oxygen transfer
.
The degree of shear is related to the desired oxygen transfer rate
.
Mix liquid/liquid
.
Use a low shear mixer when the liquid can be mixed and dissolved
.
The pumping action of the mixer mixes two or more liquids together to form a homogeneous mixture in the tank
.
If the liquid is not mixed and dissolved, then it needs some degree of cutting
.
A balance between flow and cut is usually used
.
