There are several alternatives to think about whether you’re seeking to purchase a food processor or a High Shear Mixer Machines for a lab. You have a choice of batch high shear, rotor-stator, or ultrasonic mixers.
What are the Benefits of Ultrasonic High Shear Mixers?
Ultrasonic high shear mixers are used in a variety of industries to reduce particle size and enhance emulsification. Particles are reduced to micron- or nano-sized droplets using ultrasonic high shear mixers. The creation of high-quality emulsions depends on this procedure. The (phyto-)chemical and pharmaceutical sectors both utilise these mixers.
A mechanical tool called a high shear mixer uses high shear forces to stir a liquid. It stirs a solution using a stator or rotor. The mixture is dispersed uniformly throughout the batch thanks to the strong shear pressures produced by these mixers. They are perfect for making granular goods like emulsions. Additionally, they are utilised in the creation of detergents and ointments.
Pharmaceutical manufacturers create medications, dietary supplements, and treatments in high shear mixers. They are also employed in the food business to create emulsions and granular goods. Inline flow operations can also make use of these mixers.
The mechanical operation of ultrasonic high shear mixers is identical to that of industrial mixing devices. Benchtop and industrial versions are both offered. Additionally, they come in a variety of variants that may be customised based on the energy input, sample volume, and rotor speed.
What are Rotor-stator Mixers?
Various high-shear mixer types are now on the market. While some mixers employ moving rotors, others use ultrasonic pressure waves. For complete mixing, some mixers combine the two technologies. The speed and throughput can be increased thanks to these technologies.
Pharmaceutical inks, antiseptics, tablet coatings, and vaccinations are just a few of the numerous products that high-shear mixers are utilised for. Additionally, they are employed to spread fine grain creams.
A revolving impeller is used in the rotor-stator mixer to combine particles and liquids. The speed of the tip can range from 3.2 to 8.0 metres per second. The rotor/stator assembly can be fitted either as a fixed assembly or as an inline unit. Additionally, it could include extra agitators to boost bulk flow.
Emulsification can also be accomplished using high-shear mixing. This is accomplished by applying a high-shear centrifugal force on isolated oleosomes. High throughput rates may be produced using ultra-high shear mixers, which can take the place of a colloid mill. They also cost less up front. Additionally, they are significantly simpler to maintain and clean. They can be utilised to make various dispersions as well as nutritious compositions.
What is the Need of Batch High Shear Mixers?
High shear mixers are capable of carrying out a variety of mixing tasks, depending on the application. For instance, they can spread granulating fluid or dry powdered particles. Chemical stabilisation in food can also be aided by a high shear mixer. This procedure can be used to enhance food product shelf life and save operational expenses.
Liquids are accelerated tangentially through the rotor/stator assembly in high shear mixers. As a result, the fluid moves in the direction of the shear gap. A turbulent zone between two fluids is known as the shear gap. Intense hydraulic shear is produced by the material being propelled through the shear gap.
The liquid droplets are broken down during this process before they may naturally split. This is crucial for emulsions, which are mixtures of two or more liquids. In comparison to other liquids, emulsions often have a higher viscosity.
High-shear batch mixers are frequently held over a vessel. Additionally, they can be fixedly attached to a mixer tank. A single mixing head or a multi-head arrangement can be employed, depending on the application.
Customised accessories like a heating phase tank without a water phase are examples of special installations. A control panel could also be a part of a unique installation. A unique exhibit can be produced or built in a lab.,
The Bottom Line
Mixtures that are viscous or viscous-viscous can be processed using high shear mixers. These are substances that don’t mix well. Before they may naturally separate, the mixture must be broken down by a high shear mixer. The size of the particles is also decreased using this kind of mixer.
