Design and development of high shear mixers Fundamentals
Processing & Engineering | Liquid Mixing: Solid Challenges
Pharmaceutical processing & engineering: Liquid mixing and blending would seem to be among the most straightforward of pharmaceutical manufacturing unit operations. Mechanical process mixers have been on the market for more than 100 years, and not much separates mixers for drug making from those used in food and chemical industries.

A Small Design Change with a Large Effect • In addition to pressure changes leading to cavitation, fluid jets also impinge in a mixing chamber • Extremely turbulent flow situation and very high shear forces cause additional disruption of droplets • Higher homogenization pressures possible
Taylor‐Couette reactor: Principles, design, and
Feb 03, · To increase the shear stress instead, Forney et al. proposed the rotor design depicted in Figure 7. 66 This design deliberately creates cavitation at very high rotational speeds to achieve high shear forces. The high degree of shear originating inside the reactor leads to small bubble sizes within the reactor as consequence, which increase mass

Manufacture of Shampoos - US - Industrial High Shear Mixers
These problems can be overcome by the use of a Silverson High Shear mixer, typically an In-Line mixer added to the existing process. Batch mixers and the Silverson Flashmix powder/liquid mixing system can also be used. Operation is as follows: Stage 1. The vessel is charged with water. The in-tank agitator and In-Line mixer are started, and the

Understanding High Viscosity Mixing to Achieve Uniformity
The mixing process is generally performed to achieve homogenous blending of two or more ingredients as uniformity can influence the performance, durability, stability, reaction and other factors of the resultant product. Some of the major factors to be considered for achieving uniformity include the mixer design, the times and techniques of

PDF] Scale-up of batch rotor–stator mixers. Part 1—power
Abstract Rotor–stator mixers are characterized by a set of rotors moving at high speed surrounded closely by a set of stationary stators which produces high local energy dissipation. Rotor–stator mixers are therefore widely used in the process industries including the manufacture of many food, cosmetic and health care products, fine chemicals, and pharmaceuticals.

Single-Pass Emulsification Processes in Two Different
Single-pass continuous emulsifications were studied in kerosene- and silicone oil-aqueous systems with two inline high shear mixers (HSMs) adopting two main commercial configurations, including the dual-row ultrafine-toothed and the single-row blade-screen units. The effects of the processing parameters on the measured drop sizes and power consumptions were investigated.
Mixer Selection for Paints and ... - High Speed Dispersers
Once considered state of the art in high shear mixing technology, the HSD (high-speed disperser) is a familiar sight in plants across the country. But these days it plays a minor role on most process lines. It is seldom capable of more than pre-mixing (inclusion), and it generally cannot produce what we accept as a “colloidal dispersion” today.
The Art of Mixing: High-Speed Dispersers
The High-Speed Disperser (HSD) is the basic tool used by all paint, ink, chemical, plastic and adhesive manufacturers. Although a very simple device, the HSD is often misused or misapplied. The following outlines the basic design parameters of an HSD. Normal operating viscosity range = 1,000 - 25,000 cps and up to 50,000 cps max.
