- How to increase shear without sacrificing throughput
Ultra-high shear mixers are ideal for homogenization, emulsification and solubilization requirements where particle or droplet size is critical. These devices are as simple to operate as regular rotor/stator mixers but are capable of intense hear levels as well as high pumping rates.
- Upgrade your colloid milling operation
New ultra-high shear mixers offer improved performance and efficiency over traditional colloid mills. Advantages include higher throughput, greater particle size reduction, easier cleaning and lower capital cost.
- Homogenization of submicron
Submicron emulsions are traditionally prepared in rotor/stator mixers, colloid mills and high pressure homogenizers. Ultra-high shear mixers are the newest alternatives to conventional emulsification methods, delivering higher emulsion stability, improved throughput, easier maintenance, and/or lower cost.
- Preparing superior quality
This bulletin discusses various mixing technologies for efficient processing of high-quality nanoparticle dispersions depending on rheology and shear requirements.
- Turnkey Mixing Systems
Turnkey systems range from simple laboratory mixers equipped with one or two auxiliary equipment to more complex packages capable of high speed, multi-recipe production. It helps to work with an experienced supplier capable of providing a full range of testing, engineering, design and manufacturing services.
- Multi-agitator mixer/reactors
Multi-agitator mixers are ideal for reaction processes that require intense mixing, high speed dissolution, emulsification, deagglomeration or heating/cooling of viscous liquids.
- Mixer options for pureeing and liquefying solids
A variety of mixers are suitable for pureeing requirements – from single-shaft rotor/stator mixers and high speed dispersers to multi-agitator equipment for higher viscosity formulations, and even ultra-high shear mixers which are used to achieve a high level of smoothness and consistency in some products.
- Improve emulsion stability through ultra-high shear mixing.
The droplet size distribution of an emulsion largely dictates its stability. Fine droplet sizes are produced by applying sufficient shear, often through the use of conventional rotor/stator mixers. Today, ultra-high shear rotor/stator designs are available which can improve emulsion stability of certain formulations.
- High speed mixing: saw-tooth dispersers vs. rotor/stator mixers
The saw-tooth disperser and rotor/stator mixer are two of the most widely used high speed mixers yet many are unaware of the differences in their utility and operating capacities. Knowing the unique attributes of these devices is important in mixer selection and process optimization.
- Consider the advantages and disadvantages of scrapers.
Consider the advantages and disadvantages of scrapers.
The use of scrapers in batch mixing operations helps improve product homogeneity and heat transfer efficiency. However, there are cases wherein scrapers are not recommended such as in the processing of abrasive applications or highly viscous, sticky materials.
- Ultra-high shear mixers increase overall throughput and efficiency of homogenization processes
Ultra-high shear rotor/stator systems speed up cycle time by reducing the number of passes required through a high pressure homogenizer, an inherently low-throughput, high-energy device. Since homogenizers are also generally maintenance-intensive, an efficient ‘pre-mixer’ generates significant savings in the overall cost of production. In certain applications, ultra-high shear mixers even offer a viable alternative to homogenizers.
