Liquid process equipment is not “one size fits all.” The type of industrial process equipment you’ll need depends on several factors. For example, the liquids you’ll mix, consistency, and if you’ll mix emulsions or homogenous solutions. You’ll use different liquid mixers for adhesives than you would homogenizing milk. And, you will use something different for mixing paint than you would putty.

Overall, knowing what is best for your application is important in choosing the right liquid process equipment. Let’s consider the options.

Types of Liquid Process Equipment


Mixers can be used with a wide variety of liquids of different consistencies. They are suitable for low viscosity liquids such as miscible and immiscible liquids. Also, they can help with dissolving gas into liquids and/or suspending solids in liquid solutions.  A key part of liquid mixer design is the impellers. The impellers have a design for high flow at lower power usage regardless of the consistency.  They can be used in tank volumes from 1 gallon to 4 million gallons.


Immiscible liquids— those that don’t easily blend, such as oil and water—are no match for emulsifiers. Use these when creating mixtures that need oils and water, such as lotions or cosmetics. Emulsifiers use the power of centrifugal force to break substances down into smaller materials. This makes them easier to blend.

Several emulsifying mixers are possible, including stirred vessels, agitators, static mixers, and rotor-stator mixers.


Homogenizers blend materials that don’t normally mix well. Extreme force, shear, and pressure, break them down to better blend into a smooth substance. One popular liquid that uses homogenization is, of course, milk. Homogenization breaks down the larger cream molecules that separate from the milk before this process.

Heavy Duty Industrial Mixers

Very viscous fluids can break down regular single-shaft mixers. So, the recommendation is to use heavy duty industrial mixers. Pastes, putties, waxes, and other thick substances above 750,000 centipoises handle better with planetary and multi-shaft mixers.

Overall, a solid understanding of the work you plan to do is necessary when selecting material processing and handling equipment. Working with process equipment manufacturers with in-depth knowledge of your field is crucial to determining which type of liquid process equipment will do the job. It is also important for being efficient, sustainable, and cost effective.

Paddle Mixer

A paddle mixer will also allow you to mix wet and dry ingredients or very viscous liquids on a continuous basis.  Paddle mixers can have single or double shafts. They use several paddle shaped blades to push material along much like a screw conveyor.  The wide paddles and heavy-duty shafts provide for great power to be introduced to high viscosity applications.  Paddle blenders are very gentle on the solid substrates.

Ribbon Blender

For adding a small amount of liquid added to a powder or granule, a ribbon blender is useful.  Paddle blenders are commonly used to blend powders. A fine spray head above the ribbon makes it possible to add color or liquid additives to mix uniformly or disperse liquid into the powders.
