In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous. Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration).
Mixing processes are general operations in industrial process engineering. The main goal of these processes is to make a heterogeneous physical system homogeneous by using manipulating operations. Generally, efficient mixing can be challenging to achieve, especially on an industrial scale.
This article introduces the basics of mixing technology. It defines the process of mixing and blending, and explains its importance in Industrial applications. The different types of mixing equipment for solid-solid mixing, liquid-liquid mixing, and viscous mixing are discussed.
The range of mixers available for such diverse duties is dealt with, including tumbler mixers for powders, mechanically agitated vessels, in-line continuous mixers and jet mixers. Coverage is given of the range of mixing objectives, varying from achieving product uniformity to obtaining optimum conditions for mass transfer and chemical reactions.
Having the right mixer in your tank will make all the difference when it comes to optimizing efficiency in your process. Use this guide as a checklist to look for other common issues like corrosion, staining, and agitator damage to ensure your equipment is operating properly.
Chapters 15 (powder blending), 16 (high viscosity), 19 (petroleum), and 20 (pulp and paper industry). Key design concepts for equipment selection are: Selection of tanks versus in-line mixers and use of backmixed flow versus plug flow Selection of residence times are required: long residence times are well.
Mar 6, 2024 · Mixing is a process that involves combining different substances to achieve a uniform distribution of their components.
Jul 4, 2023 · Mixing is a process of random distribution of the particles to obtain a uniform blend with respect to the drug (Weidenbaum, 1958 ). In solid dosage form, the main objective of the mixing process is to obtain dose uniformity in the finished product.
Our Mixing Engineering Guide gives access to all knowledge interesting to Process Engineers in the field of Dry Mixing to answer questions related to design or operations of mixing processes. Dry Mixing of powder and solids. Coefficient of variation - How to calculate homogeneity of a dry-mix.
Mixing is the fundamental unit operation where uniform mixture is produced by dispersing one or more components within the other. The particulate component in a minor amount is known as dispersed phase, and the larger component is known as continuous phase.
