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 (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
