The “Fluidized Bed” Operation for Mixing & Drying:
Liquid dispersion is done by spraying The unique action created by the movement of
liquids against fluidized powder, by the mixing elements produce intense but
Top and / or Bottom Mounted Nozzles. gentle intermingling of the materials of the
mix in a mechanically fluidized bed.
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
it´s mixing efficiency and
accuracy, including mixtures
with diverse specific gravities
as well as other problems such
as liquid incorporation and
heat transfer.
Mixing elements are
designed to force the
product into appropriate components of
axial & radial motion.
High-Speed Blending Choppers enhance mixing
action by controlling particle size and trace
ingredient dispersion, usually without the need
for additional process steps.
Chopper Action, sending fluidized particles upward, against
sprayed liquids flowing in the opposite direction.

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.-Complete 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

P

w
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.

Liquid Addition
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.
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 the“choppers”
deagglomerate these during the cycle.
Following the dry mix cycle, the granulation 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 degree of dispersion attained, a reduction 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 greatly enhances drying times. The introduction &
dispersion of the granulating solution depends
on the batch size. Usually requires 2-3 Minutes.
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.
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
When granulation is
done, it is clearly reflected in the Drive Current.
Cycle is instrumentated
for accurate reproducibility.
Following the distribution of the
granulating solution, the action of
the choppers change from dispersion 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.
Over 90% yield ready for shelf or fluidized
bed drying without wet screening.
