EQUIPMENT
Mill
Systems
The
Alligrator comes as a complete milling system, requiring
only the connection of the electrical supply, and the ancillary
equipment (packed inside the shipping container) to begin production.
 |
Systems
such as this portable unit ensure fast setup times when used
for refugee type applications or when disaster strikes and
a need for flours or milling is required.
All
the feeders, augers etc are loaded inside the container and
assembled when landed on site.
The
System uses the container as a housing and operates within.
|
Everything that is directly needed in the milling process is included
in the system, items such as dust collection, raw material input
feed conveying and product exit augers. The supply of a complete
system simplifies installation, maintenance, warranty arrangements
and provides the ability to fine tune the entire process.
The
"System" is controlled via a PLC (Programmable Logic Control),
which provides a simple and effective stop/start operation without
the need for an experienced operator. This level of control maintains
maximum operation parameters and efficiencies at all times. This
also allows for integration with other processing equipment.
A
1.5 MT per hour system uses a 55 KW drive motor.
Electrics
are available in 50 - 60 Hz (415 - 480 Volt 3 phase power supply)
applications.
Single
Stage Process
The
Alligrator Mill System is unique in principle but incredibly
simple in application. The unusual aspect of this system is that
it is like having two mills in one, it is a material on material
impactor, which also has a grinding capacity. This gives a more
complete and finer grind in one pass. The maximum size of input
material is 25mm.
The
Alligrator Mill System is a high-speed, wind-swept impactor with
only one moving part.
Pulverisation
is achieved by material to material impact with hammer speeds of
100 metres per second and accelerated particle speeds of up to 200
metres per second, and an adjustable anvil. This action occurs within
an artificially induced vortex which, by nature of the shape of
the mill, causes size reduction without the use of screens.
The
robustness of this mill allows for uncleaned wheat to be milled
and produce a high grade of wholemeal flour.
Minimal
Heat Generation
Product
temperature is on average 4 - 8° Celsius above ambient. Air
conditioning and chilled water cooling of the mill housing and bearing
oil can be provided, when even lower operating temperatures are
required. Low temperatures and no internal screens, ensure products
flow freely through this system, even high oil content products
such as soya beans, can now be milled easily, without prior steaming
and drying.
Because
of the energy efficiency and compact size of the Alligrator Mill
System, the entire processing system can be contained in one
small sealed tower. Compact size, the sealed tower and new and efficient
Nitrogen generation means that, for the first time, it is possible
to create a viable "Oxygen
Free"* milling and packaging environment. This process
eliminates rancidity, which is a major health problem and also provides
a much longer shelf life. "As fresh as the moment it was milled"
will be a reality.
The
Alligrator Mill System is small and efficient, an entire
1.5 ton per hour milling system can be installed into, and operated
in a 20 foot shipping container. A 'Food Relief' version has been
produced for Food Aid relief groups, Governments and Humanitarian
agencies. The System ancillaries pack completely inside the container
for transport. Once delivered, the complete system takes less than
one hour to assemble, ready to produce flour. The only other requirement
is a generator or mains electrical supply.
Easy
Cleaning
A
fully accessible entry door exposes all the internals of the mill,
allowing for easy and fast hygienic wash-down, enabling compliance
with rigorous Food Grade and Organic Certification standards.
Size
Floor
space is a major cost saving factor when using the Alligrator
Milling System. A 3 tonne per hour system mounted in a vertical
processing tower complete with all the ancillary equipment, including
raw product delivery, screening and packaging, would have a footprint
of only 16 square metres.
A
complete system capable of processing 1.5 tonnes per hour can be
mounted and operated within a twenty foot shipping container. This
has major implications for food relief operations.
So
far, three sizes of mills have been designed: 150 kilogram per hour,
1.5 tonne per hour and 3 tonne per hour. These ratings are based
on hard wheat and would vary depending on product density. This
makes these mills perfect for niche applications in specialty foods
processing.

Diverse
Products
The
Alligrator Milling System can mill an extraordinary range
of different products, from nutriceuticals to organic raw sugar;
all using the same mill, with no modifications required. There are
no costly pre-treatments such as steaming and drying for oily products
like linseed or soya bean. Products such as herbs and spices, grape
seeds/skins, dried kangaroo meat, pharmaceuticals, cosmetic clays
and many more can be milled to a fine powder and in a single pass,
without losing essential oils and aromatics.
Organic
raw sugar high in molasses content is easily milled into icing sugar
without any problems.
The Alligrator Milling System can mill an extraordinary range
of different products, from nutriceuticals to organic raw sugar;
all using the same mill, with no modifications required. There are
no costly pre-treatments such as steaming and drying for oily products
like flaxseed or soya bean.
The
Alligrator Milling System sets a new standard in diversity. The
term "difficult milling characteristic" is seldom associated
with the Alligrator, as most foods mill easily using this system.
When almost any foods can be processed, using the same equipment,
the ability to diversify a business or product line is a far simpler
operation.
Diversity
provides the ability to pick & choose your product range according
to availability, market demand and profitability. Now a healthy
choice is available to processors and consumers alike.

Current
food processing technology is now dated by over 100 years. A quantum
leap in food processing will enable innovative food processors and
manufacturers to be years ahead of their opposition. Manufacturers
who can commit to the functional food sector with innovative and
customized products are now going to be winners.
The
restrictions faced by milling equipment sales companies are that
they all offer the same restrictive equipment and have done so for
many years. They all offer what is available today and they do it
very well, but when the market changes or technology progresses,
can they move with the times? What do they offer that is new? None
of them can cater for the diverse range of materials, varying throughputs
and delicate natures of products supplied by the organics industry.
The
supply of these healthier foods will have to keep pace with demand.
Existing infrastructure cannot keep pace with either the quantity
or quality of the foods being demanded. Whether it is to the farmer
or to the processing factory operator, the Alligrator provides many
opportunities and solutions for the problems facing the food industry
today. How do you service the changing market of tomorrow with the
rigid equipment of yesterday? The small physical size of the Alligrator
Milling System allows the entire system to be used in an "Oxygen
Free" milling/packing process contact
us for details (link to sales contacts) where rancidity is not
initialised during the milling process, and allows for extended
shelf life of products without additives.
Research
indicated that most companies today do not have a permanent engineering
division as was the case a few years ago. Our company took the initiative,
and designed our milling system as a basic "plug in and work"
type system. To our customers, this means fast and simple installation
procedures where our trained commissioning team assemble the system,
connect to mains power, (or a generator if in a remote area) connect
the raw material feed conveyor, and the product out feed, and the
equipment is operational.
Using
our own integrated dust collection system means no fugitive dust,
no guess work trying to connect an external dust collector, and
allows the fines to be used as product if required.
Electrical
The
Alligrator Milling System utilizes variable speed drives
in the main mill drive motor, in the feeder drive motor, and in
the dust collector extraction fan drive motor.
These
variable speed drives reduces the start up current significantly
on mill start up and saves severe shock loading on components unnecessarily,
as well as giving operational variability.
The
feeder drive and the mill drives are linked via a PID loop to allow
constant adjustments to be made to the feeder rate based on mill
motor loading to ensure constant mill loadings are maintained without
overloading.
Alligrator
food mills are available in 1.5 tph and 3 tph systems.
