Acoustic Mixing : Mixing Materials Without Impellers
Butte, MT -- Resodyn Acoustic
Mixers, Inc., is pleased to announce the commercial
availability of laboratory and production scale mixers,
which utilize the company’s proprietary technology,
ResonantAcoustic Mixing® (RAM). The newly patented
technology uses low-frequency, high intensity sound energy
to provide intimate mixing of gas-liquid, liquid-liquid,
liquid-solid, or solid-solid systems.
RAM technology applies a
consistent shear field throughout the entire mixing vessel
and has proven to mix complex combinations of various
materials with very consistent results. This unique
technology substitutes low-frequency acoustic energy for
traditional mechanical mixing impellers. The application of
acoustic energy is uniformly distributed throughout the
mixing chamber and efficiently mixes products and thus,
generates less heat compared to conventional mixing
technologies.
ResonantAcoustic Mixing technology is very effective for
hard to mix systems, such as powders of disparate particle
sizes and densities, slurries, nanomaterials, or viscous
pastes and adhesives.

RAM mixers use no probes,
impellers, or other internal components. As a result, there
can be considerable flexibility in the vessel used for
mixing. In-vessel sealed mixing is particularly desirable
for hazardous compounds. Waste of expensive fillers such as
precious metals, or nanocompounds can be reduced, or
eliminated by mixing in the end-use container.
The bench top mixer, LabRAM, is a
versatile mixer for testing, laboratory use and smaller
production quantities. Mixing may be done directly in the
container. No clean up is required.
The RAM 5 mixes without impellers
and is capable of mixing one pound (500 grams) to 80 pounds
(35 kg) of material. Various combinations of gases, liquids,
solids, powders, viscous liquids and pastes are thoroughly
and consistently mixed with this innovative technology. The
RAM 5 is the only noninvasive mixer capable of mixing over
10 kg of materials with viscosities beyond 100 million cP.
RAM mixing is easily scaled from the laboratory to
production.
Resodyn Acoustic Mixers, Inc.
located in Butte, Montana is the premier supplier of
ResonantAcoustic mixers to laboratories, universities and
industries around the world. The company designs,
manufactures and markets advanced mixing systems using
low-frequency, high intensity sound technology patented by
Resodyn Acoustic Mixers, Inc.

New 2 and 3-way Tube Diverters
from DMN
 The
Netherlands -- DMN Inc. has recently introduced their new 2-
and 3-way TDV tube diverter. As the existing TDV type was
due for re-evaluation, it was thus decided to design and
produce a 2- and 3-way diverter of similar construction to
the M-TDV multiport diverter. The M-TDV is available with 4
up to 24 ports on the smaller pipe sizes, therefore the new
2- and 3-TDV seamlessly connect with the M-TDV range.
DMN
already has a two way tube type diverter which has been in
its product offering since 1996 and was due for
re-evaluation with regard to the requirements of today.
Contrary to the M-TDV with electric drive, both the new 2-
and 3-TDV are activated using a pneumatic actuator, which is
more cost effective. This gives a very compact design to
both diverters and by using an additional line cylinder on
the 3-TDV very accurate positioning is achieved.
The
uniquely designed seal that has already been proven on the
M-TDV is also being used on the new 2- and 3-TDV. This seal
is made from EPDM and is very easy to fit and clean, and
being inflatable guarantees absolutely tight sealing in the
conveying line up to 43.5 PSIG. (higher on request) This
also applies to liquids.
The
whole range of tube diverters (2-, 3- and M-TDV) are of a
sanitary design and have stainless steel AISI 316 product
contact parts with a multiple choice of line connections,
ranging from a simple pipe connection to a milk coupling.
The swan neck pipe connecting the inlet to outlets is
designed to give minimum product degradation in every
conveying direction. All conveying lines that are not in use
are also sealed at the diverter outlet. This ensures that
there is no air or product leakage from destinations that
are not being used.
The diverters are designed to be easily removed from the
line for cleaning (COP – cleaning out of place). It is also
possible to purge the individual conveying lines with a
cleaning liquid without removing the diverter from the line
(CIP – cleaning in place). Removal from the line is only
necessary when a complete cleaning operation is required.
This gives the customer the option to chose a cleaning
method tailored to suit their process.
There
will also be a very competitive 2-TDV 14.5 PSIG hybrid
design available, constructed out of aluminum and stainless
steel, having all product contact parts made from stainless
steel and using a static silicon seal instead of the
inflatable EPDM.
DMN
has been designing and manufacturing rotary airlocks,
diverter valves and other related components for the bulk
solids industry for more than 35 years. Based off our wide
range of products, DMN offers application specific solutions
for all industries, e.g. chemical, food, plastics,
pharmaceutical and minerals.
Besides an extensive range of standard versions, we supply
components that are conforming to USDA requirements and/or
DMT pressure shock certified to 145 PSIG explosion
containment without flame passage. In addition, DMN supplies
components that are ATEX compliant to European Directive
94/9/EC, including for use with ST2 rated powders.

"SolidQuid" : The Solid Liquid
Delivery System
 Kalamazoo,
MI -- Hapman, the leader in powder handling systems,
introduced the "SolidQuid". This new solid/liquid delivery
system will utilize your existing liquid delivery equipment
to convey precisely measured amounts of bulk powders from a
FIBC bulk bag to your mixing tank. If your application
requires automatic and precise delivery of dry bulk
ingredients to a slurry or mix tank and you have a liquid
delivery system already in place, simplify and think
SolidQuid.
Using
large bulk bags and an unloader as your solid material
source allows your processes to continue for extended
periods of time with little or no human intervention. There
is no need to add a mechanical conveyor, for handling the
powders and bulk solids, when you use a SolidQuid system.
Its unique design automatically prevents clumping, reduces
mixing time, dusting, and energy consumption, saving you
time and money in your production process.
The
versatility of Hapman's SolidQuid system will add efficiency
to just about any industrial blending process which needs to
combine dry materials and liquids on a large scale. If you
need to mix powders and liquids, start with the SolidQuid
system from Hapman and maximize your total process
efficiency.
Hapman
is the world leader in providing powder and bulk material
handling equipment and systems. The product line is used
extensively in the handling of powders and bulk solids for

System Batches both Wet and Dry Materials
Cincinnati, OH -- Ingredient
Masters, Inc., a manufacturer of precision batching
equipment for the food, pharmaceutical, and chemical
processing industries, has introduced an innovative
system for sequentially introducing dry and liquid
materials to a mixer.
The heart of the system is a
"Super Sack" bulk material handling system, which
incorporates multiple air-actuated dispensing hoppers, a
robotic scale cart which moves between them, and an
innovative, space-saving support structure. Dispensers
are polyethylene, and with capacities between 3.5 cu.
ft. and 105 cu. ft. There are ten standard dispenser
sizes.
Other components include a
vacuum transfer system, a fiber handling
("loss-in-weight") scale hopper, and a 50-lb. bag
handling system with multiple hoppers. The hoppers are
agitated, and are equipped with screw feeders; they
discharge above a common platform scale.
The liquid handling portion
of the system discharges three to seven ingredients;
surge tanks feed continuously and are refilled via
gravity flow each time a full tote is connected to the
system.
Centralized computer control
is via an Allen Bradley PLC and a PC. Software is
Allen-Bradley RSLogic 5000 for the PLC logic and RSView
for operator graphics. A Microsoft Access database
stores recipe and ingredient information, and records
batch data.
An unlimited number of
recipes can be stored; each is date-stamped with the
most recent revision or approval. A master list of
ingredients, including operating parameters for each, is
maintained in the database. The system maintains a
deductive inventory for each dispensing hopper and
tracks ingredient lot numbers for recording in the batch
data.
The scale cart discharge
accuracy depends on the batch size, and is generally
0.002 lb. to 1 lb. per batch, a tolerance which makes
the system well-suited for the broadest range of
applications.
