What is a High Shear Mixer

High Shear Mixer

An inline high shear mixer features an inlet that feeds ingredients perpendicularly into the shearing zone, and an outlet discharging product axially. Unlike a batch mixer, an inline mixer feeds and outputs material in a continuous stream. The material is then often perfectly hydrated, emulsified or homogenized in a single pass. Batch mixers, by comparison, require ingredients to be mixed for longer periods of time in a tank, and 100% dispersion is rarely achieved lowering product yields and wasting valuable ingredients.

High-shear mixers offer a few advantages over batch mixers. They allow for a more controlled mixing environment, they’re less bulky, they allow for continuous inline mixing and they can produce results within a fraction of the time.

How do high shear mixers work?

When a force pushes part of an object in one direction and another part of the object in the opposite direction within the same parallel plane, this is known as shear.

A liquid mixer or powder disperser uses a rotor, rotating at high speeds, to direct material outwards towards a stationary stator and thus shear the material. Variable rotor speeds provide the ability to uniquely tailor the amount of shear energy for each application. This technique can be used to mix a liquid, solid or gas into a liquid with which it ordinarily would not easily mix.

High-shear mixing can be used for homogenization, dispersion, emulsification or particle size reduction.

The difference between high shear mixer and high-pressure homogenizer?

Industrial high shear mixers rely on rotor/stator shearing action, whereas high-pressure homogenizers utilize high amounts of energy to form pressure differentials to homogenize or size reduce ingredients. High-speed, high-shear rotor/stator mixers are able to close the gap between traditional rotor/stator mixers and high-pressure homogenizers into submicron size reduction.

What are the practical applications of high shear industrial mixers?

Hundreds of consumer products require the mixing or dispersion of liquid or solid compounds. For example, salad dressings, paints, cosmetics, cleansers, shampoos, ointments, and toothpastes are all products that use high shear mixing to produce products of consistent quality. High shear mixers excel at dispersing hard-to-wet powders and rheology modifiers.

Application examples High shear mixers are typically used for:

1.Liquid-liquid emulsification and homogenization

2.Different viscosities of liquid-liquid mixing

3.solid-liquid suspension

4.Powder-liquid dispersion

5.particle size reduction

Do laboratory models of High Shear Mixers exist?

Yes – in fact, using a laboratory high shear mixer is a practical way for those with liquid processing needs to test the technology with different applications. It’s also a quick, convenient way for your R&D department to evaluate processing strategies and formulations before scaling up to production capacities.
