» Process » Blend

If you blend substances together or if they blend, you mix them together so that they become one substance.

Blend has very similar meaning of mix. Sometimes blend and mix can be replaceable. But blend is more popular to be used in food industry when referring to kitchen appliances.

The above mentioned substances include solid, liquid, semi-solid and gas and you can blend any of these substances whether they’re naturally soluble or insoluble.

Blend is the most general term as mix and includes different methods for different applications including stir/agitate, disperse and homogenize.

Blending operation has two basic types as mechanical blending and gas-flow blending. Mechanic blending is much more popular and widely used in every industry.

Low shear blending generally refers to the blending by slow speed anchor stirrer, scraper and impeller etc. High shear blending generally includes high speed dispersing and rotor/stator homogenizing.

When blending easily miscible liquids of similar viscosities, an agitator will produce satisfactory results. But where there is a significant difference in viscosity between the two liquids, an agitator tends to move the two liquids around without actually blending them together and it can take a long time to achieve a uniform blend.

With a Ginhong high shear mixer, the positive mixing action of the rotor/stator assembly draws the liquids into the work head where they are rapidly combined before being forced out through the stator and projected back into the vessel. The liquids are blended almost instantaneously.

With some applications, such as continuous dilutions or when the materials react on contact, a Ginhong inline mixer is most suitable. Typically the secondary liquid would be introduced into the pipeline just upstream of the inline homogenizer so that the liquid streams are subjected to intense high shear on contact, resulting in a homogeneous blend in a single pass.
