The Fluidized Bed Operation for Mixing Drying
The unique mixing action of the FKM series
mixers is accomplished by a horizontal shaft
which revolves at a high rate of speed rapidly
projecting and hurling the mix materials
away from the vessel wall into free space,
filling the entire vessel. The mixing action
causes the materials to crisscross in the
direction of the vessel walls and inversely back
again, providing a high volume rate of material
transfer. The mechanically fluidized bed of
particles is the basis of its mixing efficiency
and accuracy, including mixtures with diverse
specific gravities as well as other problems
such as liquid incorporation and heat transfer.

Drying in The Littleford.
1.-High efficiency drying of Suspensions, pastes,
and bulk materials. 2.-Fast drying cycles and
discharge. 3.-Allows efficient drying of
sensitive materials at low Temperatures. 4.-Comple
te dispersion of agglomerates, lumps and fiber
bundles. 5.-Homogeneous mixing of dissimilar
ingredients. 6.-Drying operations from liquid
state to free-flowing powder in one
vessel. 7.-Allows liquid addition during
processing. 8.-Adapts itself to effective
recovery of costly solvents. 9.-Eliminates need
for additional processing equipment.
The Key to this State-of-the Art drying
technology is the unique,
mechanically fluidized ploughshare ction which
agitates and individualize the solid
particles to be dried. The ploughshare
action forces the product into a
3-dimensions motion that individualizes each
particle, continuously exposing tremendous
surface area for drying. The particles
constantly contact one another, and the
heated interior walls of the jacketed vessel
furthering the drying process. Our dryers are
also equipped with independently operated, high
shear choppers, to reduce the particle size of
the lumps or agglomerates, to expose undried
materials and ensure thoroughly dried particle
interior. Deagglomeration further shortens
drying time.

Advance Drying

The Chopper Advantages in Drying Fast,
efficient drying without lump formation
The action of the turbulent plows and the high
shear choppers reduce the forming lumps to
smaller granules, thus exposing large amounts of
new surface area for drying.

Liquids Dispersion Systems
Improved wetting
characteristics. Minimization of
Liquids usage. Complete
uniformity of dispersion.
Increased Productivity.
Any application requiring high-quality
dispersion of liquids into powders .

Granulating The FKM Advantage
Littleford mixers/granulators, equipped with
plow-like mixing tools, develop an intermediate
intensity mix action, which is gentle, yet
thorough. This action is supplemented by
high shear choppers, which quickly disperse
minor liquid, or powder ingredients. In a
typical run, the excipient and the powdered
active ingredient are charged to the static
granulator and mixed, with choppers, for several
minutes, until the power curve levels off,
indicating that dispersion is complete. Then
the agglomerating liquids are sprayed into the
active chopper field, where they are quickly
dispersed into the batch.

The degree of granulation, and thus the amount
of power utilized, is dependent upon the
amount of liquid added to the batch, so as of
the wet mix batch time. The action of the
curved-sided plows guarantees more spherical
granules, and the choppers action controls
particle size distribution.
16
Granulation Cycle 2 to 5 Minutes. Reduction
in Granulating Solution. Less Drying Time, due
to the above. Excellent Granules Flow
Properties. Mixing and Granulating in the
same Vessel 10 Min. for Both Operations.
Wet Granulation Littleford Advanced Solutions
The various ingredients are weighted and fed to
the Littleford Mixer / Granulator, by hand or
vacuum- feed systems. Pre-Milling to eliminate
lumps that may have formed in storage is not
required, as thechoppers deagglomerate these
during the cycle.
Complete uniformity of mix is usually attained in
about One Minute. Most pharmaceutical companies
mix an additional 2 minutes to complete
deagglomeration and dispersion of dry colors
Following the dry mix cycle, the gra- nulation
solution is fed to the mixer through 1/2 liquid
injectors mounted over high speed blending
choppers Spray nozzles are not always required
as the choppers quickly disperse the liquids.
Due to the de- gree of dispersion attained, a
reduc- tion in the amount of granulation
solution is usually possible, if compared to
low-shear systems. 10 to 20 in starch paste
reduction is typical. Even greater reductions are
attained with alcohol granulations. Liquid
reduction great- ly enhances drying times. The
introduction dispersion of the granulating
solution depends on the batch size. Usually
requires 2-3 Minutes.
When granulation is done, it is clearly
reflec- ted in the Drive Current. Cycle is
instrumentated for accurate reproduci- bility.
Following the distribution
of the granulating
solution, the action of the
choppers change from disper-
sion to agglomerate control. Over sized
agglomerates are constantly broken up and
reformed into fairly uniform spheres. The size is
based on cycle length
Discharge consists of spheres.
