Dry to liquid blending is an often misunderstood and misapplied process.
Commonly rotary agitation is used at the expense of product quality, consistency and
processing time. True D-T-L blenders can provide rapid mixing with vast improvement in
consistency and quality. The Tri-Clover tri-blender is an excellent and inexpensive means
for improving your process. Contact us to arrange for factory testing or a rental unit for
in-house testing of your product.
In-line blending has increased in popularity based on continuous
manufacturing techniques and also as an outgrowth of the food and beverage industry.
In-line blending can accurately mix varying rates of numerous ingredients continuously or
simply add one ingredient to a batch. However in either case, the ease and quality
enhancements can quickly justify the cost.
High shear blending can describe types of DTL blending, but also refers
to "in-tank" blending with high tip speeds or a rotor/stator arrangement. Used
for difficult to mix solutions and suspensions, this is an economical method to achieve
The common term "agitation" is vastly over worked and often
misapplied but congers the image of a top mounted propeller type mixer. This is the most
common, and cost effective means available and is suitable for a myriad of applications.
Units are available in a broad range of sizes with various drives, mounts, seals, shaft
and blade configurations including hundreds of options and features. Lab size units are
also available with programmability and computer interface.
In-tank blending can include basic agitation as well as high shear
mixing but can also be expanded to include surface scraping and counter rotation in
virtually any combination. Unfortunately, it is impractical in most cases to retrofit this
type of equipment, making it advisable for inclusion with the original vessel design. See
our section on Tanks and Processing Vessels.
Today's trends toward automation and accuracy has expanded the market
for metering extensively. Units of all sizes, shapes, designs and accuracies are available
for metering and blending both batch and continuously with single or multiple ingredients.
Improved accuracy has allowed subtractive control to minimize equipment costs while
improving cleanliness and operating simplicity. Meters are available with all standard
connections, finishes and ranges in the following types:
A) Mass Flow
D) Positive Displacement
