Single-Pass Emulsification Equipment and Solutions

High Shear Performance and Productivity in a Single Pass

Faster batch times. Higher capacities. Predictable, consistent quality. Easy to clean.

These are the demands that are challenging process engineers in large-scale manufacturing today. However, traditional in-tank fluid mixing continues to impose limitations on productivity – causing bottlenecks that the industry has reluctantly learned to live with or work around by introducing costly additional processes.

Conventional hit-and-miss

Traditional in-tank dispersion and emulsifying methods are, at best, hit-and-miss.

Powders and immiscible liquids introduced into a vessel of liquid must find their way to the mixing impeller in order to be effectively sheared and dispersed. In theory, the vortexing created by a conventional impeller draws the powder down into the action zone. In reality, only a portion of the material introduced will reach the tooling for processing.

The result? Random, uncontrollable rates of shear.

Some materials are continually recirculated back into the action zone – leading to overprocessing. Other components, most often in "dead zones" nearer the vessel walls and surface, remain virtually untouched. This incomplete dispersion not only promotes waste as materials "raft" on the tank surface or build up on walls and baffles, but it also encourages the creation of "fish eye" lumps.

It’s easy to see why even the most powerful mixer often has limited impact. To compound the situation, traditional vortex flow induction introduces unwanted air into the batch mix, further compromising the desired results. And because these results are the product of so many randomly impacting processing variables, batch-to-batch quality and consistency become wholly unattainable. Processors have traditionally attempted to overcome these problems by extending processing times or using more costly, higher horsepower mixers.

However, these approaches can damage heat- and/or shear-sensitive products.

Single-pass emulsions

With the Quadro Ytron® line of mixers, dispersers and emulsifiers there’s now a proven, viable alternative that removes these obstacles to greater efficiency. This unique in-line technology maximizes yields, creating high-quality dispersions and emulsions by applying the required shear to all the material in a quick, single pass. And its wide range of tooling can be specifically tailored to the difficulty of the application.

Quadro Ytron®’s breakthrough, single-pass process delivers high product quality that is not only predictable, repeatable and scalable, it can dramatically reduce batch times and energy consumption by as much as 75%.

In-line processing offers a host of additional advantages. Powder wastage, air entrainment and batch-to-batch cross-contamination are virtually eliminated.

Clean-up is fast and easy. What’s more, Quadro Ytron® technology is flexible enough that a single device can even process multiple applications feeding several batch tanks. No wonder single-pass processing is rapidly gaining momentum among leading processors. As pioneers in this revolution, Quadro offers the expertise, track record and advanced technology to meet the growing demand.

Solution profile

Meeting Tight Deliveries Through Faster, More Consistent Processing

"Not only did Quadro Ytron®’s speed and versatility allow us to reduce our batch times from 72 to 8 hours, but we were also able to free up manufacturing space, plus reduce inventory and warehouse demands while still meeting tight 3-day deliveries."

Rapid dispersion of high-viscosity thickeners - Carbopol®, HPMC and Keltrol®

Quadro was approached by a large personal care product manufacturer producing private label shampoos, creams and lotions for global distribution by health & beauty product retailers. Their conventional in-tank process was impeding productivity, and limiting batch quality and consistency. Delivery deadlines were potentially at risk.

At the Quadro R&D Test Center, we audited their process, providing a solution that eliminated lumps, “fish eyes” and air entrainment, rapidly dispersing high-viscosity thickeners such as Carbopol®, HPMC, and Keltrol® into water and alcohol during the liquid fill cycle. In addition, wax flakes are instantly dissolved at reduced temperatures, saving cooling time.

Powders are dumped from a mezzanine into the hopper of a ZC3 Powder Disperser, with a liquid feed from the water supply line and short discharge directly into the mixing vessel. A full-flow ball valve maintains the mass flow of powder through the hopper.

Single pass dispersion of extremely difficult to wet powders

The Quadro Ytron® ZC Powder Disperser is uniquely engineered to incorporate and disperse extremely difficult-to-wet powders into a liquid stream in a single pass.

Intense shearing

The advanced design of the ZC Disperser’s rotor/stator and reactor head provides for intense shearing of powders prior to hydration, to produce homogeneous dispersions that are completely free of lumps and "fish eyes".

Dramatic powder and batch time savings

A near-perfect vacuum, created by the liquid seal between the rotor and stator, permits concentrations up to 25% by weight to be generated in a single pass with minimal air entrainment. Because the powder is completely hydrated, yield is maximized and wastage is reduced or eliminated, translating into powder savings of up to 30%, compared to processing with in-tank or other in-line high shear technologies. In addition, the over-processing common with conventional dispersing technologies is entirely eliminated, preserving the rheological properties of shear-sensitive products.

Batch time reductions as high as 75% can be realized with the Quadro Ytron® ZC Disperser technology. No dispersion aids such as pre-heating the water or the pre-dispersion of ingredients into non-aqueous solvents are required. Even with difficult products such as hydrocolloid gums, cellulose gums and carbomers you can expect complete dispersion in a single pass.

Sanitary design options

There are three sanitary-design models available, offering liquid throughputs up to 120 GPM (454 L/min). An optional vacuum delivery system is also available, for completely dust-free operation.

  • The XC Powder Disperser has a dual-stage reactor. 
  • The first stage creates a strong vacuum to draw the powders into the reactor head.
  • Immediately after the powder comes in contact with the liquid, the premix is subjected to intense directional and velocity changes as it impacts the stationary baffles.
  • The lower stage tangentially discharges a smooth, lump-free, homogeneous product.




Quadro Ytron Y Jet Mixer

In tank mixing system for liquid blending, powder incorporation, and dispersions

The Quadro Ytron® Y Jet Mixer uses a unique rotor/stator mixing head that creates a purely axial flow discharge jet to provide efficient in-tank mixing and blending. The wasteful radial flow and vortexing that are the downfall of conventional open-impeller design mixers are gone forever. Air entrainment is virtually eliminated – without the use of baffles.

Uniform velocity profile

The Y Jet Mixer’s strong axial flow pattern produces a uniform velocity profile, throughout the vessel with no stratification or dead areas, improving heat transfer rates and reducing batch blending times by as much as 80%. The Y Jet Mixer’s flow characteristics are ideal for the suspension and re-suspension of high-settling-rate solids.

Rapid sub-surface dispersion

An innovative by-pass tube makes use of the strong negative pressures at the Y Jet Mixer’s rotor to draw powders and liquids directly into the rotor/stator head. The result is the immediate sub-surface dispersion of powders and viscous pastes into the liquid phase. Shear is applied to the product as it is discharged from the bypass for single-pass incorporation.

Dust-free powder handling

Depending upon the nature of the dry ingredients, a variety of dust-free powder handling methods, such as wanding from bags or totes, are available for delivering powders to the bypass tube. In addition to ensuring maximum mixing performance, dust-free handling reduces health and safety concerns, minimizes cross-contamination, and eliminates the need for expensive material conveyors.
