Mixers are machines that blend, homogenize, emulsify or otherwise mix materials and substances into a single substance. They thoroughly combine virtually any solid or liquid that is necessary to form a final product.
The main purpose of an industrial mixer, sometimes called a tank mixer, is to serve as a catalyst for combining different substances or stirring settled materials. Many companies rely on them because mixing is often a first step for products that require further processing.
Mixers are used throughout many industries during the manufacturing or processing period. Their powerful motors and blades allow mixers to work with a wide range of materials. These machines are widely used across many industries including the cosmetic, pharmaceutical, research and lab, chemical, agricultural, food and beverage, pulp and paper, automotive, water treatment, adhesive and sealant industries.
In these industries, mixer customers process products like: toothpaste, glue, petroleum products, cement, biodiesel, dry and wet chemicals, medicines, syrups, beverages such as milk, medical ointment, lotions, creams, vitamins, shampoos, detergents, toothpaste, hair dye, petroleum products, silicone, adhesives, polyurethane and many other products or ingredients. Mixing devices are also commonly employed for agitating chemicals and creating fused solutions.

The History of Mixers
The first mixer was a small, domestic model patented in 1856 in Baltimore, Maryland. From then on, every year or so, another type of mixer, like the whisk, was patented. It wasn’t until around 1885, though, that the first electric motor was invented. It’s believed that it was that year that an American inventor named Rufus Eastman invented the first electric mixer.
The company that truly ushered in the age of the commercial and industrial mixer was the Hobart Manufacturing Company. They were designing mixers as early as 1908, when one of their engineers, Herbert Johnson, invented the first standing mixer. By 1915, his 20-gallon model was being used widely in commercial bakeries all over the USA. Non-food mixers have also been around in some form or another since the early 1900s.
Over the past one hundred years or so, mixers have improved in effectiveness, efficiency and versatility. They’ve also come to be able to take on huge amounts of material at once, without wearing down.
Though mixers vary by size and design, the majority consist of: a large tank or vat, a head or cover attachment, and motorized blades or flat paddles that rotate on a stationary shaft. The attachments or heads are generally removable to maximize the mixer's effectiveness with different materials.
Other mixer designs use stationary blades and a tank that rotates. Furthermore, manufacturers have even created different styles of blades that have higher performances based on the material they are mixing.
Most mixers are made from stainless steel material; this is because stainless steel is sanitary and corrosion resistant. However, some mixers are made from thermoplastic, titanium, steel, cast iron or aluminum.
When designing mixers, engineers think about a few key aspects. These include: placement of the paddles, the design of the blades, the power of the motor, what additional characteristics the mixers may require. Additional characteristic considerations may include, for example, the need for a mixer to provide significant pressure drops, or the need for a miser to be capable of handling large particles moving at high velocities.
While custom mixers are not terribly common, they are available. The most widely available specialty machines are used to perform to exact specifications, so that operators can better control the mixing process without causing excess wear and tear.
Mixers range from as small as portable food processors to as large as mixers that stir 55-gallon drums. Mixers, depending on the application, may have sharp blades or large flat paddles.
Industrial mixers are typically powered via electric motors operating at speeds of 1800 RPM or 1500 RPM; to help reduce speed and increase torque, the motors are paired with gearboxes. Very small mixers, like lab mixers, may work using magnetic mixers.
Regardless of their power source, mixers work by agitating, or mixing, liquid and/or solid substances until they are evenly distributed (ex. animal feed) or homogenous, or blended (ex. flour and water mixing). They either run in batches or continuously, depending on application needs.
Mixers are unique because they provide a service that their customers could not practically accomplish without them. Any other mixing processes are slow and tedious.
There are several types of industrial mixers including: ribbon, high shear, paddle and more. Certain mixers are specialized for particular applications. These applications usually have broken down their processes into an exact science based on required ingredients.
Ribbon shaped mixing blades are flat and thin and are used in static mixers. These mixers do not have any moving parts. Instead, they use carefully designed obstructions that force the flow of materials to mix and blend together. Because of the simple arrangement of the stationary blades inside, a static mixer is sanitary and easy to clean.
High Shear Mixer
High shear mixers are ideal for industries such as pharmaceuticals, paper manufacturing, food preparation, cosmetic manufacturing and more. This style of high speed mixer is known for processes called homogenization, emulsification, disintegration and dispersion. It also offers particle size reduction of many different solid and liquid materials.
Planetary mixers are named after the motion they use to mix substances. Planetary mixing agitators orbit around the outer edges of a mixer bowl on a circular or elliptical axis. Primarily, they’re used in cooking applications, like making dough, but they can be used to mix chemicals as well.
Stand mixers, as their name suggests, are mixers that stand upright. To do so, they’re mounted on top of their motor. Manufacturers make stand mixers in all sizes, from 25 gallon plus commercial models, to 1-gallon countertop home models.
For a breakdown and complete blending of a material, use a homogenizer. Homogenizers have been used for a number of years in many industries, including science and technology, food processing and in some industrial mixing processes. Two examples of commonly homogenized products are milk and cream.
Because their main functions are secondary to the larger process, agitators are basically process aids. Agitation is not very effective with thick, highly viscous materials. However, if you need to mix substances with low viscosities, like liquids, an agitator may work quite well for you.
There are also very specific kinds of mixers that are used with certain materials or to product a certain effect. Food mixers are one such mixer design. Food mixers, also known as food processing equipment, blend, mix, fold, whip, beat or knead multiple edible ingredients in food packaging processes. These mixers must meet certain regulations and be completely sanitary.
In-line mixers can handle extremely large batches with much lower horsepower than other mixers. Also, they have a predictable batch turnover. For those reasons, they’re becoming quite popular for use with large volume operations. They can be divided into two groups: dynamic in-line mixers and static in-line mixers. Dynamic in-line mixers work using a combination of pump pressure and high-speed rotating elements, while static in-line mixers work using specially contoured stationary mixing elements. These are located in a tubular housing that functions as part of the pipeline.
Advantages of Mixers
One of the biggest advantages regarding industrial mixers is the consistency of output. They are known to mix and blend products thoroughly and efficiently time and time again. In addition, because the parts of a mixer can be machined and assembled with precision and with quality materials, they tend to perform better and last longer.
Proper Care for Mixers
As with all industrial equipment, if you want your mixer to last, you have to make sure to use it only with those materials for which it is meant. Likewise, only fill and run it to the capacities, speeds, and frequencies it is designed to handle. Otherwise, you risk premature wear and tear or a total machine breakdown. It’s also important that you properly clean your mixer in between batches. If you’re dealing with food, medicine, or chemicals, you need to follow the right protocol to avoid cross-contamination. Aside from that, even negligible powders can build up and clog or slow down your mixer.
To optimize efficiency, do these things: 1) only blend something as long as necessary (don’t overblend); 2) make sure your mixer has the right horsepower.
It is of the utmost importance that the mixing machine you purchase be reliable and durable, especially if you are working with materials that take a long time to be mixed thoroughly. One way to ensure that the mixer you’re getting is high quality is by asking for certain standard certifications.
For example, one universally advantageous standard code is the ASME (American Society of Mechanical Engineers) code. If need be, your manufacturer should be able to provide you with an ASME stamp. Other standard certifications you may be interested in securing for your industrial equipment may include: USFDA, BISC, ABS, API and UL. Largely, standard requirements depend on your industry, application, and region.
