• Progressing Cavity Pump Solves Long-Term Dairy Product Pumping Problem

    For a major, Wisconsin-based dairy products company, a progressing cavity pump handled the difficult task of transferring sweetened condensed milk out of flash coolers — solving a 25-year-old pumping problem. The NEMO pump provided by NETZSCH features a flexible rod design that eliminates the need for lubrication and protection against mechanical damage or corrosion. Since its installation, the pump has significantly reduced pump downtime, resulting in time, labor, and money savings.

  • The Color Of Peanut Butter - More Than Meets The Eye

    Did you know that Americans consume more peanut butter than any other country? Over 90 million jars are sold annually, one about every three seconds. About 75 percent of all American families purchase peanut butter, enough to make 10 billion peanut butter and jelly sandwiches a year. That’s about 500 million pounds of peanut butter or three pounds per person every year and consumption is increasing


  • Best Practices For Conducting Virtual FAT’s In Food Manufacturing

    When the COVID-19 pandemic hit, it became critical that manufacturing plants remain open and operating to provide essential items such as food, beverage, sanitation supplies and more to consumers. New practices were put into place to ensure the safety of all and maintain efficient, effective operations. A critical aspect of keeping up with consumer demand has been the testing and acceptance of new equipment. With consumer packaged goods (CPG) companies reluctant to bring suppliers into their facilities and service technicians limited in their ability to travel due to COVID-19 protocol, the industry has had to get creative to complete the process.

    Whether you're considering a tumble blender for your process or shopping for a suitable piece of blending equipment, here are 10 things you should think about before the making final decision.

  • 5 Steps To Increase Energy-Efficient Mixing

    Mixer testing simulation trials are needed to confirm the suitability of a specific mixing strategy. This white paper explores five ways to increase energy efficiency in new and existing mixing processes.

  • The Quest For Clean Mixing

    Mixing is one of the most common operations in food processing, but comes with challenges -- batch-to-batch uniformity, optimizing blend times, and most importantly: improving cleanliness.

  • Solutions To Batch Mixing Issues

    Mixing processes vary from one application to another and there are no fix-all solutions.This white paper presents some strategies for improving commonly encountered batch mixing problems.

  • Efficiencies In Powder Dispersion For Manufacturers

    Uniformly dispersing powders into a liquid batch in a practical amount of time is a common problem for F&B manufacturers. This white paper explores five tips for dispersing powders more efficiently.


The ROSS Model HSM-405SC-25 is an inline high shear rotor/stator mixing system incorporating SLIM (Solids/Liquid Injection Manifold) Technology. Unlike conventional eductors, the unique SLIM rotor/stator generates a powerful vacuum without the aid of external pumps and pulls powders directly into the mix chamber, promoting instantaneous wet out under high shear conditions. Mounted on a multipurpose skid with load cells, actuated valves and level switches, the pictured HSM-405SC-25 recirculates into a 400-gallon jacketed tank and is controlled from a 15” industrial PC with Windows.

Cannabis-infused products and medical marijuana are at the forefront of an innovative and promising industry. Fueled by a growing consumer base and increasing investor enthusiasm, the cannabis industry is opening the doors to a new generation of cosmetics, beverages, foods, nutritional supplements, pharmaceuticals, and even pet food & wellness products.

Rental blenders available for a nominal monthly fee. Test the AC+ dry blender in your facility to ensure it works well in your current system.

The AC+ Dry Blender uses the proven design of a tube within a tube and a centrifugal pump, but with the improved shaft and threaded impeller nut construction of the AC+ pump.

AC+Dry Blender 2116 System is easily integrated into existing systems. All wetted components are 316L stainless steel. Blenders run up to 25 feet of discharge pressure. Pressures above 25 feet require a discharge pump. Hoppers are available in 60°, 304 stainless steel.


Industrial food mixing usually refers to the process of combining two or more separate components to produce a certain level of homogeneity. Mixing is often an interchangeable term with blending. However, where blending is typically a gentler process, mixing can combine ingredients at more aggressive rates to create a homogenous mixture. Most processed foods start with a mixing process to achieve physiognomies that are imperative to the final product like homogeneity, texture, temperature, and structure.

The key objective of industrial food mixing is to have unvarying distribution (homogeneity) in the product. Typically, the homogenization consists of particle size reduction, which is achieved by the action of shearing forces. Homogenization is most-commonly known in the processing of milk.

Different products have different objectives, such as creating a stable emulsion. An emulsion is a product of mixing two immiscible liquids. Common examples in food processing would be creams, soups, sauces, mayonnaise, and margarines.

Industrial food mixing equipment is offered in various styles. The style that your food-making operation needs will be based on many different factors, such as, but not limited to: what is being mixed, desired viscosity, desired particle reduction, batch size, the facility’s available manufacturing space, energy costs, discharging options, cleaning, and sanitation options.

The most-common styles of industrial mixing equipment are:

  • High-Shear Mixers — disperse one ingredient into a main, continuous ingredient (liquid) which typically would be immiscible. A rotor and stator, or an arrangement of rotors and stators, is used either in a tank holding the solution or in a pipe where the solution would pass through to create shear.
    • Batch High-Shear Mixers — ingredients to be mixed are fed from the top into a mixing vessel. These are typically used when larger volume and quicker processing is required.
    • Inline High-Shear Mixers — the rotor-stator arrangement is contained in a housing with an intake at one end and discharge at the other. Ingredients are drawn through a pump array in a continuous stream. They offer a more-controlled mixing atmosphere, require less floor space, and can be part of a continuous process.
  • Heavy-Duty Mixers — these mixers are for highly-viscous materials such as dough, peanut butter, confectionary syrups, beverages, sauces, and pastes.
    • Dual- or Multiple-Shaft Mixers — these mixers have an array of two or more independently-driven agitators working together. Typically, one is a slow-paced agitator to continually move the bulk of the material (two-wing or three-wing anchor blades) and high-shear mixers to continually mix the batch to the desired consistency. Often times, it could be the combination of two paddle-style impellers.
    • Planetary And Double-Planetary Mixers — both of these can have helical-finger style blades or rectangular stirrer blades. They are used when a mix requires no air being whipped into the mixture. These mixers rotate and move all around the mix container passing through the entire batch. An example of when a dual-planetary mixer would be used is if you were mixing butter, large blocks of cream cheese, and various viscous ingredients together.





Rick Earley, National Sales Manager, Admix took some time out at Pack EXPO 2014 to talk about how manufacturers can achieve energy efficiency and sustainability with mixing technologies. 

An overview of the full range of equipment used in the manufacturing of food products. Included are dry blenders as well as low viscosity and high viscosity fluids mixers and dispersers. The operating theory of each unit and typical application examples are reviewed.

Charles Ross & Son Company manufactures a wide range of sanitary high shear mixing and dispersion equipment for fine emulsion and homogenization requirements. Many models are available to permit a client to select the exact machine for particular process needs.
