Important basics of dispersing

A thorough understanding of dispersion is essential for excellent results in many areas. In paint manufacturing, the dispersion process is a critical step for gloss and color intensity. Inadequate dispersion can lead to visual impurities and reduce quality. The right medium and the use of specific dispersing equipment are therefore crucial.

The success of emulsifying or suspending depends on biocides and other additives that reduce bacterial contamination. A comprehensive tutorial highlights the influencing factors and shows how to achieve a stable composition. For an efficient application, it is important to carefully control the change between shear forces.

The influence of phase boundaries and interfacial tension

When tiny particles are dispersed, the interfacial tension between two phases becomes noticeable. Special additives or intensive shear forces can reduce this tension and create a homogeneous phase.

Different types and their use in the dispersing machine

Modern dispersers offer different designs. An inline disperser from Ystral or other manufacturers is suitable for processes with a high throughput. The product is continuously fed through the rotor-stator system. Laboratory models with smaller motors, on the other hand, offer flexibility for test series.

What role does the shredding energy play?

The intensity of the energy used has a significant influence on the particle size. Higher shear force shreds particles faster, which promotes a more even distribution in the medium. It is advisable to adjust the power level of the machine to the desired effect in order to avoid heat and ensure product stability.

Choosing the right disperser

The choice of a suitable disperser depends on viscosity, shear rate and particle size. When dispersing in large quantities, a robust drive system is essential. A powerful motor ensures that the dispersion remains constant over a longer period of time.

A container with sufficient volume makes it easier to work with variable batch sizes. An ULTRA-TURRAX has proven itself in the dispersion of suspensions and emulsions. The high shear rate produces optimally distributed particles that ensure a uniform consistency. The snap-in mode in modular systems makes it possible to quickly switch to other stirring or cutting tools.

The shape of the particles influences the end result. A distinction is made between:

Stirring systems have proven themselves in tests when processes need to run without excessive energy input. Precise temperature control indicates the degree of dispersion and prevents unwanted heat build-up. This allows production to run smoothly and produces high-quality products.

From emulsions and suspensions: Applications in practice

Emulsions and suspensions are indispensable in many industries. Optimal mixing requires intensive shear forces to finely disperse solids or liquids. The dispersion efficiency depends on the interaction of shear gradient and residence time. Achieving a uniform quality requires not only the correct design of the equipment but also the use of rotor-stator arrangements with speeds between 10 and 24 m/sec. This supports the careful production of suspensions for cosmetics or pharmaceutical products.

Homogenization and fine distribution: Possibilities in the process

When dispersing, the aim is often to distribute the finest particles evenly. A stable process flow is particularly important in large production batches. The right machine must generate sufficient shearing action to keep emulsions stable or prepare suspensions homogeneously. Many manufacturers use emulsifiers and stabilizers to ensure a uniform structure and prevent the phases from separating.

Why the rotor-stator principle is crucial for dispersion processes

The rotor-stator system utilizes high shear and thrust forces, which is essential for emulsifying or suspending. This technology is versatile as it provides a constant intensity and can therefore ensure a uniform particle size. Whether the preparation is liquid or contains solids, the interaction between the liquid and the machine is crucial. In the cosmetics industry, precise homogenization plays a key role in product quality. A controlled set-up of these processes also ensures reliable results over many batches.

Lotions such as Calamine benefit from stabilizing additives. Bentonite in concentrations of around 1.25% binds particles and counteracts sedimentation, which is important at higher solids concentrations. In aqueous formulations of zinc oxide or talc, the pH value usually remains in the neutral or slightly alkaline range. Pectins or ultraamylopectin are also used to influence the sedimentation behavior. These adjustments help to achieve constant product properties on an industrial scale. Even fluctuating input quantities can be buffered thanks to suitable mucilage so that nothing segregates unintentionally. A controlled procedure with defined parameters guarantees a consistent distribution of all particles in the end. This strengthens the consistency of the end product and supports further processing in many industrial applications.

Important devices: IKA, Ystral and inline dispersers

Devices from IKA and Ystral are established solutions for professional dispersing machines. The Cavitron CD inline processor system is specially designed for the production of liquid mixtures or fine materials. These systems offer advantages for manufacturing industries by homogenizing components and keeping them stable.

Precise processes are essential when using inline technology. In the cosmetics or food industry, ingredients must dissolve or chemically combine with each other to achieve a homogeneous result. Many designs allow powders to be drawn in under vacuum, which facilitates dispersion and reduces dust pollution.

Typical applications and batch sizes in cosmetics and food

Batch sizes range from small laboratory batches to large productions. Process systems from Maschinenfabrik Gustav Eirich GmbH & Co KG or EKATO SYSTEMS GmbH offer flexible options. Hygienic designs and sophisticated pump systems meet high standards of purity and efficiency.

Equipment features for the best results when emulsifying or suspending

A safe circuit ensures clean processes. The selection of precise aggregates and the ability to homogenize effectively are crucial for success. Users appreciate the continuous operation in which solutions quickly dissolve or chemically combine and ultimately remain homogeneous. A CIP system shortens cleaning times and supports reliable production.

Reliable cleaning in sensitive areas is an important aspect. A CIP system removes residues directly from the cycle without contaminating the product. This ensures consistently high quality and shortens set-up times. Suppliers such as AxFlow GmbH or IKA-Werke GmbH & Co KG offer suitable options for their systems.

Those who want to work with maximum flexibility in dispersion will find innovative solutions from EKATO SYSTEMS GmbH or Maschinenfabrik Gustav Eirich GmbH & Co KG. These systems make optimum use of mechanical forces and design the mixture efficiently. This produces a stable result that has proven itself in numerous production processes.

Why the medium plays a decisive role

The choice of medium is crucial for the best results in the dispersion process. A suspension, whether thin or highly viscous, requires specific shear forces and targeted energy input. Temperature control plays a central role in the stable distribution of particles. In food production, a reproducible process is essential, which requires a constant energy supplyand process stability.

Modern dispersers are often digitally equipped, which enables precise speed adjustment. Constantly monitored operation ensures uniform homogenization of the end product. This results in emulsions or suspensions with a long shelf life. Optimum process control and careful media selection result in finer particle structures and effective mixing. This facilitates demanding tasks in many industries.

Efficient mixing and dispersing on a laboratory scale

New methods for mixing and dispersing simplify many work steps. Laboratory systems often process liquid or paste-like substances. The right design is crucial to ensure that the shear forces act evenly and can be used for cosmetic products. High efficiency is achieved through precise stirring processes in which the disperse phase remains in a stable form.

Laboratory mills are particularly suitable for smaller test series and enable

• Particle size reduction to nanometer level in the laboratory bead mill
• High-speed multi-effect grinding for optimum homogenization
• Adjustment of grinding media size and rotation speed for different applications
• Easy integration into pilot or small batch processes
• Compact designs that are easy to use

How vacuum and shear gradients influence the result

Vacuum processes minimize air entrapment, which can reduce energy requirements. Controlling the shear gradient leads to finer dispersions. An attempt is made to keep the interface between the particles as small as possible in order to avoid unwanted clumping. The mixing parameters obtained from studies such as Ascanio (2015) demonstrate improved process control through precise adjustment of the operating conditions.

Snap-in mode for flexible process design

The quick change of tools via snap-in mode increases flexibility. This adaptation is particularly advantageous on a laboratory scale, as several formulations are often tested here. Users benefit from a modular system that is designed for different viscosities and formulations. The system adapts without long changeover times.

Study data on stirred tanks and static mixers underline the importance of optimized parameters. Turbulent flows increase product quality by double-digit percentages and at the same time reduce energy consumption (Grenville & Nienow, 2004). Researchers such as Henzler (1978) have shown that homogeneous mixing of liquids and gases increases reaction yields. These findings can be transferred to laboratory processes.

Laboratory grinders also offer precise control. Metzner and Otto (1957) described how an adapted agitator for non-Newtonian media improves mixing by up to 30 percent. Pahl (2003) emphasized the role of dynamic mixers for highly viscous substances. Such approaches help to ensure quality and scalability. As a result, precisely tailored mixing processes increase economic success.

This interaction between laboratory mill and disperser creates first-class conditions.

Process optimization in the production of suspensions and emulsions

Dispersing enables the combination of substances that do not dissolve by themselves. The phase boundaries of the substances to be mixed are crucial here. Forming a small interface and preventing the phases from flowing together quickly are key aspects.

The homogenization of liquid droplets and solid particles to similar sizes improves long-term stability. The aim is to break down solid particles into equally sized pieces to prevent separation of the end product. The addition of powder enables application-specific process design.

Modular process plant and continuous operation

A modular system design allows for flexible processes. Operators can customize steps to produce emulsions or suspensions in different batch sizes. Continuous operation is advantageous for high efficiency. The technology can also be adapted to different production volumes.

The right dispersing tools for different substances

High-quality dispersing tools are essential for optimum results. The rotor-stator principle generates high shear forces that effectively break down particles. The system remains controllable without particles clumping together again. This leads to even distribution and protects sensitive formulations from instability.

Typical stumbling blocks and how to avoid them

When using dispersers, different substances often come into contact with each other. These mixtures, both emulsions and suspensions, require careful processing. Without the right emulsifiers and stabilizers, they remain unstable. The integration of rotating parts requires special attention to viscosity and temperature.

Technological advances have become increasingly important over the last ten years. Today, they are decisive for competitiveness. In contrast, market factors have become less relevant.

In traditional processing, errors often occur when components are processed incorrectly or too quickly. This impairs the homogenization of the end product. IDW S6 demands demonstrable competitiveness, which requires reliable process control.

Resource efficiency has been gaining in importance since Ernst Ulrich von Weizsäcker introduced the term in 1995. Early planning of the process flow minimizes the risk of lump formation and poor mixing performance.

The following points illustrate common problem areas:

• Inadequate matching of temperature and speed in dispersers
• Failure to check viscosity before the start of each operation
• Failure to use suitable tools for different solids
• Too radical a ramp-up when rotating parts are already in operation

Tackling individual process steps step by step leads to stable results. Companies that focus on technological progress and careful process design improve their market position. Adapted equipment and correct sequencing will disperse any material efficiently.

Tips for the correct use of dispersing equipment

A targeted approach with dispersing equipment ensures better results and stable processes. To keep particles as finely dispersed as possible, it is advisable to precisely control the shear gradients. If you use a modular system, you can react flexibly to different batch sizes. For difficult media, sufficient free space inside the container helps to ensure that nothing overflows.

Many users find it helpful to briefly check how much energy is being consumed. Peak speeds are not always ideal. A controlled approach often produces the necessary yes in the result and avoids unnecessary material losses.

Why emulsifiers and stabilizers influence the phase boundaries

Emulsifiers reduce the interfacial tension and make it easier to mix different liquids. Stabilizers also act at the phase boundaries and keep the result homogeneous for longer. If you keep an eye on the shear gradients, you will achieve a product that forms fewer undesirable lumps and remains finely dispersed.

The influence of speed on homogenization

A high speed often produces even smaller droplets. The end product remains stable if there is sufficient free internal space. A modular approach to process control protects sensitive components. For large batch sizes, a staged production process can save valuable time.

Yes for precise selection: Some models excel with high speeds, others rely on robust shear gradients. An overview of typical appliances shows the price range and possible speeds.

Interfacial tension remains of central importance in liquid formulations. Yes is created when the end product is precisely tailored to customer requirements. A controlled shearing process leaves particles finely distributed and stable.

After all, it is worth planning enough free interior space for every application. After all, this enables a trouble-free process and reduces cleaning costs. Finally, the interfacial tension must not be ignored during the entire process.

Careful dosing keeps everything finely distributed so that the recipes run smoothly. A modular design adapts to variable batch sizes and encourages flexible work processes.
