Welcome to the Milton Roy Mixing’s newsletter which will provide you with useful insights and expand your knowledge about mixing applications and the latest news related to Milton Roy Mixing products.
In many processes, mixers play a much bigger role than it seems.
Water treatment, Energy, Mining, Chemistry, Food industry, etc. no matter the sector, good mixing defines good results.
A well-designed mixer isn’t just equipment. It can improve your entire production process.
Industrial mixers accelerate transfer phenomena: Heat transfer and Mass transfer. They inject energy and motion into the fluid.
This motion is what enables every process operation: blending, dissolving, diluting, reacting, stabilizing, heating, cooling, and separating.
Here are the main physicochemical phenomena and related applications where mixers are absolutely essential.
Each is explained simply with everyday examples, supported by industrial applications.
Heat transfer describes how temperature is spread within a system. Uneven temperature distribution can limit process efficiency, even when heating or cooling capacity is sufficient.
Inside a tank, reactor, or storage vessel, heating or cooling is rarely uniform. Achieving a uniform thermal environment requires temperature homogenization.
Optimized processes, improved product quality and consistency without losses, reduced energy spends.
Mass transfer describes how substances are spread within a system. It occurs through two main physicochemical phenomena: dilution and dispersion. Both rely on effective mixing.
Dilution is the reduction of product concentration.
By adding a liquid, usually water or a solvent, the liquid that is too concentrated is diluted.
A mixer ensures the product is spreading evenly.
Consistent concentration, across the entire batch, batch after batch.
Blending is the most common application that relies on dilution phenomena.
Blending, or general mixing, is the combination of two or more ingredients to create a uniform product.
From ingredients to final mixtures, the mixer creates uniformity.
Consistent and reproducible quality, texture, quality, and performance.
Coagulation is a well-known process built on dilution mechanisms.
In water treatment, coagulation is a process that neutralizes the negative charges around particles. By neutralizing these charges, the particles no longer tend to repel each other.
On the other hand, coagulation generally refers to the transition of a dispersed system (liquid, suspension, colloid) toward a more solid or agglomerated state.
The mixer creates the right turbulence to aggregate small particles to form small flocs.
Faster process time, improved separation and cleaner flocculation or downstream processing.
While dilution is associated with concentration, dispersion drives how substances are distributed.
It is a physicochemical phenomenon that enables the uniform distribution of one phase within another: most often through the dispersion of tiny solid particles or droplets in a liquid.
A mixer creates the mixture by breaking the particules and distributing them evenly.
Stabilization of the suspension over time, product quality improvement.
Emulsification, dissolution, gas dispersion and suspension are typical dispersion applications.
Emulsification creates a stable formula of two liquids that don’t normally mix like oil and water for instance.
A mixer breaks big droplets into tiny ones, stabilizes the emulsion, ensures uniform texture, and prevents phase separation.
Stable, uniform emulsions. Without mixing, the liquids quickly separate into layers.
Dissolution is melting a solid, or another liquid, in a liquid.
By keeping both the liquid and the solid in motion, mixers increase liquid-solid contact. That helps solids to dissolve faster and speed up the process.
Uniform solution with shorter processing time.
Some particles naturally settle at the basin or tank bottom. This accumulation requires regular cleaning and has huge negative impacts.
Mixers keep the particules floating, preventing particles from settling to the bottom.
Stable suspensions, no contamination risks, no damaged equipment, reduced waste, 100% usable tank volume.
Flocculation is a well-known process built on this mechanism.
Right after coagulation, flocculation enables the formation of flocs, which grow in size through the addition of a flocculant (most often a polymer).
In some processes, these flocs can be filtered and removed more easily. In others, the flocs are the final product (like cheeses!).
Low-shear mixers preserve floc structure and enhance floc growth thanks to a gentle and controlled agitation.
Less sludge and lower handling costs, preserved flocs and sensitive product integrity, optimal process efficiency, less chemical consumption.
Those processes are widely used in fermenters and bioreactors.
Aeration is the process of injecting air or gas bubbles into a liquid to oxygenate it or strip unwanted gases. It is a process applied in water treatment, agrifood, cosmetics and pharmaceutical industry.
A mixer helps to:
Aquarium aerators providing oxygen to fish
Fermentation processes: Anaerobic fermentation happens when microorganisms break down organic matter without oxygen, while aerobic fermentation occurs with oxygen, allowing them to break it down more completely and produce more energy.
Mixers dramatically increase efficiency, saving energy and time with shorter batch times.
Enhance process, long-term cost savings, higher product output.
