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.

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 action 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,
continuosly 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.

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 t hey 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 plows causes “snowballing”; the choppers generates small,
granules.

Natural Blends
Uniform mixtures of aromatic vegetable parts such as ground bark, flower
buds or seeds with leaves are rather difficult to attain due to their dissimilar
shapes and densities, so as for their tendency to segregate on discharge.
The fluidized bed mixing action of the FKM mixers does not rely on gravity,
producing a completely homogeneous mixture in a matter of seconds Discharging the unit with the plows rotating prevents segregation of the product
and rapid discharge of the materials. The thorough, but gentle and rapid discharge blending action does not reduce particle size of friable materials during normal blend cicles.
Soluble Spices
There is a growing use of spice extracts, or oleoresins, due in part to their advantage of showing no speckling in light colored foods. However, these oleoresins have the handicap of being very viscous and difficult to coat on suitable
carriers. The Littleford mixer, equipped with choppers, can uniformly coat the
surface of sugar,salt or dextrose with oleoresin in a short mixing cycle,without
requiring post-milling. Reductions in mix times, as high as 90% have been reported for this application.
Meat Cures and Preservatives
Uniform, Free flowing mixtures of salt, sodium nitrate and sugar used to enhance the flavor, color and yield of meats can be produce in minutes. It is capable
to encapsulate certain additives to prevent contact with moisture. This coating
action is attained by a combination of chopper action and the inherent high
heat transfer required to melt and congeal the coating.

Powdered drink formulations contain a very high percentage of
fine sugar, which is usually delivered to the mixer on an automated basis. The minor dry ingredients are usually preweighted
including several in a premix form, and manually added during
the blending cycle. If liquid addition is required, a very fine atomized spray is desirable,since the sugar dissolves readily in the
water, forming a sticky agglomerate. High speed choppers are
useful in dispersing the minor additives, like the vitamines, as
well as enhancing color development. Length of time in which
the choppers are used determines desired particle size.

The intense mixing and deagglomerating action of the
high-speed choppers, combined with the mexhanically

Desolvation
Steam Stripping & Solvent Removal
The Littleford Day desolvation technology is an efficient and economic means of recovering solvents and making the remaining
products more suitable for re-use or disposal after the extraction process of plant materials has taken place.
A considerable
portion of the ingredients for the Food, Pharmaceutical, Nutraceutical & Biotechnical Industries is manufactured from the extraction of plant materials using solvents.
The extract is used either as an ingredient or may be sold directly to the consumer (i.e.
Vanilla, cola, paprika, etc.).
The extraction process typically utilizes a solvent such as alcohol, acetone, hexane, etc. To dissolve and remove a soluble resin from an insoluble
solid. This process leaves the processor with waste in the form of an insoluble solid, which still has a fairly high level of solvent. In the past, due to
the solvent levels this waste has been land filled as the only recourse for the processor. But, with higher and higher costs for land filling items with
solvents and the fact that these insoluble solids have value, processors have been searching for an economical way to remove the solvents.
Typical Littleford Process Steps:
1.- The insoluble solids are placed in the
Littleford Ploghshare Vacuum Dryer.
Agitation is initiated (plows & choppers), followed by direct steam injection into the Dryer to raise the temperature of the solids and to initiate the
release of the solvent from the permeable solids.
2.- After an appropiate period of time,the
steam injection is completed. The vessel is still under vacuum, & the product is dried to remove the excess moisture and remaining solvents.
3.- The insoluble solids that have been
cooled somewhat via vacuum evaporation are then cooled further (via cooling water on the vessel jacket) to the
appropiate temperature & subsequent
processes are completed (i.e. Other ingredients added,product granulated or
product discharged, etc.
Littleford Day has drawn upon its process technology and advanced
Ploughshare action to develop a system for the solvent removal
from these solids. The Littleford system steam strips, vacuum dries
and cools the product, all in the same vessel which eliminates additional handling, thus decreasing the amount of labor hours required
for the process, avoiding cross contamination of product.

ciple, whereby the materials being processed are man
tained by the plow shaped mixing elements in a mechanically fluidized “suspended” state. This permits the mediums (steam and solids) to achieve intimate, individualized, rapid contact with each other and then the heat transfer surfaces. In addition, it may be equipped with independently
operated, high shear “chopper” devices to reduce the particle size of the lumps or agglomerates thereby exposing undried (solvated) materials
and ensuring thoroughly dried/desolvated particle interiors. Deagglomeration further shortens the drying/desolvation time required.
The Littleford Ploughshare Vacuum Dryer has been specifically engineered to maximize heat transfer coefficients , which are many times higher
than those of traditional dryers. This advanced heat transfer technology allows fast, single-unit desolvation. It can be enhanced with an optional
Littleford Pulse Back Filter to effectively handle the vapor stream created during steam stripping and drying.
The Littleford Pulse Back Filter is
used to filter the vapor stream from the Dryer in order to prevent product carry-over into the condenser. The filter is heated slightly higher than
the dew point of the vapor, thus preventing condensation. Filter bags of proper porosity are mounted over stainless steel cages and can easily
be removed through th top section of the filter housing. A pneumatic pulse jet system provides continuous automatic bag ceaning down through
a venturi at the top of the bag.
Since this pneumatic shock wave cleans only one row of bags at a time, there is no interruption of vapor flow
through the filter. This provides a smoothly operating dust control system for the Vacuum Dryer.
The Littleford Ploughshare Vacuum Dryer is designed and constructed according to “GMP” and to meet or exceed FDA,
3A, USDA compliance as specified by the customer.
This proven Littleford technology has been applied to numerous complex and difficult applications in the Food, Nutraceutical and
Biotechnical Industries.
Littleford Ploughshare Vacuum Dryers can be purchased in a varietyof sizes to meet most production
requirements. Littleford can interface its system controls with existing equipment or supply fully automated process control systems.
Sterilization & Inoculation of Growing Media
In the growing of fungi, yeasts, bacteria, etc. For the Food, Pharmaceutical and Biotechnology
Industries, it is imperative that the producer (grower) begins with a sterile growing media and avoids
any possibility of cross contamination of that media. Typically the grower purchases a sterile growing
media in pre-weighted small individual containers, creating the need to individually inoculate each
container by hand. Subsequently the grower will manually mix in the inoculum and eventually mix all
the small containers together to form one large batch. These processes are quite labor intensive and
lead to the real possibilities of cross contamination.
In addition, this procedure does not allow the
grower the flexibility and control they require to best satisfy their customer´s needs. Littleford Day
has drawn upon its process technology and advanced Ploughshare action to develop a vastly superior system for the
sterilization of growing media and the inoculation of the media.
The unique part of the Littleford system is that both the
sterilization and the subsequent inoculation occurs in the same vessel, thus eliminating the possibility of cross contamination or contamination in different steps of the operation.
Typically the Littleford process follows these steps:
Media is placed in the Littleford Polyphase Reactor/Mixer Low speed agitation is initiated followed
by direct steam injection into the media to raise the temperature & pressure within the mixer
sufficiently to denature all organisms.
After an appropiate holding period, the mixer is evacuated & the batch is cooled and dried utsing
evaporative cooling.
The sterile media is cooled to the appropiate Temp. & moisture level, inoculated, homogeneously
mixed & delivered to the producers next step (i.e. Fermentation, holding, etc.).
1.- Controlled sterilization through effective and
optimum heat transfer.
2.- Improved cooling rates.
3.- Increased efficiencies of Sterilization and
Inoculation.
4.- Single unit processing of the entire process.
5.- Less labor intensive.
6.- Lessening the chance of cross contamination.
7.- Handling different types of growing media.
8.- More control and flexibility.

Chocolate Paste Mixing & Cream Centers
Cream Centers
Chocolate Paste Mixing
A critical operation in the manufacture
of chocolate is the preparation of the
paste prior to refining & final conching.
The efficiency of the refining operation
depends on the consistency & uniformity of the paste.
Leading chocolate
manufacturers have installed our units
to improve this important process.
Cocoa butter, dry milk solids and fine
sugar are rapidly blended into the chocolate liquor to form a uniform paste
ideal for refining. Increases in refining
throughput as high as 30% have been
reported. High speed blending choppers enhance this operation by reducing the mix cycles to approximately
three minutes and completely eliminate
agglomerates of dry milk solids.
Batch and continuous mixers have been
supplied for chocolate paste mixing.
Due to the short mix time required, the
unit manufacturing costs have been
reduced while attaining an improvement in product quality.
With the introduction of dry, free
flowing fondant, a major change in
production techniques for butter
cream centers has been developed.
The utilization of a Littleford mixer
to compound these dry fondants
with other ingredients to form the
cream center has resulted in drastic
reductions in process time & operating costs, while improving the consistency of product. A typical procedure would be to first add the fondant, either dry or cooked, to the
mixer. The fondant would then be
creamed by the addition of butter in
approximately 30 seconds by the action of the mixing plows. Flavorings
are then addes and the mixing continued for another 30 seconds. At this
point, fillers such as chopped walnuts are added and bleded into the
base in about 15 to 25 seconds.
Some formulations require a consistency adjustment by the addition of
dry fondant prior to discharge to the
extruder. The entire mix cycle takes
less than 5 minutes per batch, depending on ingredients and quantities.

Chocolate Cold
Milk Additive
Uniform dispersion of a viscous
soya-lecithin liquid into cocoa
powder has been found necessary
to achieve the desired instant solubility of a powdered drink mix in
cold milk. This incorporation may
be accomplished in a Littleford
mixer by using a special technique
developed by Littleford for adding
the soya-lecithin liquid and thoroughly dispersing it into cocoa.
Sugar, flavoring and other ingredients may then be added to complete the mix.
Chocolate Flavored
Compound Coatings
A highly successful alternative to
traditional mixer-refiner process
system has enabled bakeries to attain
substantial savings by preparing their
own coatings. An air classifying mill
reduces the particle size of the sugar,
cocoa & milk solids to the desired
range, and a Littleford mixer suspends
these materials in vegetable oils.
In a typical installation, the vegetable
oil is added first to a jacketed Littleford
batch mixer equipped with blending
choppers. The discharge from the mill
is then added continuously to the
mixer. The action of the plows, which
constantly move the viscous material
into the high-speed choppers, creates
a uniform suspension almost inmediately. The compound is finished in an
approximately ten-minute cycle following the addition of dry solids.
The finished compound is then pumped directly to storage or high-speed
enrobing machines.
Tabletted Candies
Absolute uniformity of mix is required for the successful direct compression of breath
mints & similar candies. High speed choppers uniformly disperse the flavors & colors
through the sugar in minutes. Lumps that may have formed during storage of the raw
materials & agglomerates of color are quickly broken up by the chopper action during
the mix cycles. Appearance and strength are improved.
