Overview
Camas International is the manufacturer of a new line of
high-tech machinery which can substantially increase the
efficiency and profitability of a wide range of agribusiness
activities, including flour milling. Based on patented
technology developed by Dr. Arthur Zaltzman, an
internationally renowned scientist and engineer, our
machines create a fluidized bed to sort, clean and upgrade
all types of grains, oilseeds, pulses and nuts.
The Camas separation technology is so precise that particles
with density differences as small as 2% can be separated. At
this level of precision it is possible to remove mycotoxincontaminated kernels, foreign matter and other undesirable
materials usually missed by other cleaning equipment. Our
unique sorting ability also provides a powerful tool for
quality control and product formulation. In contrast, gravity
tables require density differences of at least 13% to operate;
but healthy and contaminated products rarely exhibit density
differentials of this magnitude. As a result the Camas
separator can operate with a far lower reject rate, saving
up to 25% more good product from rejects than
alternative equipment.
Principle of operation
The Camas separator uses fluidized bed technology for very precise
separation of agricultural commodities. Although the physics of
fluidized beds have been used for several decades, it was not used for
separation of materials. The technology needed for separation, for
which patents have been granted by thirty countries, has been
developed by Camas. The application of this technology has been
proven in facilities in ten countries, on machines which have run
thousands of hours.
Many types of commodities can be separated in the Camas machine,
but the principles are the same for each. Using wheat as an example,
micro jets of air are forced through the bed of a chamber loaded with
wheat . With the addition of vibration, the wheat then behaves like a
dry liquid. The chamber is sloped slightly, allowing the fluidized
wheat to flow to the lower end. Light, less dense kernels float to the
top of the grain mass while the more dense particles sink down.
At the end of the chamber the dry liquid stream is divided by a valve.
The light particles, which consist of diseased, damaged, and
underdeveloped kernels plus light foreign material, are removed from
the top of the stream as rejects. The heaviest particles, which are the
healthiest and most dense, are sent to the good product hopper. The
intermediate particles are sent on to the next chamber for further
separation. Another chamber designed specifically for removal of
heavy impurities removes up to 99% of heavy impurities.
The Camas separation technique is so precise that particles with
density differences as small as two percent can be separated. This is
far more accurate than the 13% density difference required by gravity
tables, the most widespread cleaning equipment currently in use.
The two percent difference is sensitive enough to remove mycotoxininfected kernels from healthy grain. This has been proven for corn,
wheat, peanuts, beans, rice, sunflower seeds, soybeans, pecans,
almonds, and peas. It is also precise enough to do many other types
of separation never before possible.

Features & Benefits
Although the Camas separator is the most accurate
high-capacity machine on the market, it can actually
save on operating expenses by replacing several
pieces of less efficient equipment, saving valuable
floor space as well as lowering maintenance costs.
Because of the precisely controlled air distribution
system that is used to fluidize the product stream, the
dust control system requires far less CFM of air than
traditional air legs, concentrators, sifters, gravity
tables and de-stoners.
The combined savings from increased product
yield, lower operating costs, and lower air
requirements for dust control adds up to a
significant competitive advantage for owners of
the Camas separator, and a quick payback on the
machine, usually six to fifteen months!!

Application for Wheat
The Camas SV Series is the best high-capacity wheat cleaning
machine on the market. The SV4-8 can clean up to 1000 bushels
of wheat per hour with better quality and lower reject rates than
competing equipment. As a result, one Camas separator can
often replace several less efficient cleaning machines. One
elevator operator reports that "this one piece of equipment is
doing twice as much production as our former screen cleaner
and gravity table combined." Another user stated that "a single
Camas machine has replaced a Buhler de-stoner, three grading
machines and three gravity tables.” Specific applications of the
Camas separator with wheat include:
A. General Cleaning (including garlic): The Camas separator
is unparalleled in the removal of all types of foreign material
from wheat including wild oats, wild weed grasses, frost
damaged, sprouted, and shrunken kernels, wild garlic and insect
damage. In recent tests the Camas separator has removed over
90% of wild garlic bulbs from previously uncleaned wheat. In
one test garlic bulbs per 1,000 grams declined from 289 to
1!!!
Applications for Wheat
B. Heavy Impurities Removal/De-stoner:The
optional heavy impurities chamber of the Camas
Separator is the most accurate de-stoner available,
regularly achieving rates of 98-100%. In a recent
head-to-head test, the Camas separator outperformed
a traditional gravity de-stoner by more than four to
one. The heavy impurities chamber is also extremely
effective at removing glass, metal, and other
impurities often missed by simple de-stoner.
C. Deoxynivalenol (vomitoxin):The Camas
Separator has repeatedly proven its ability to
effectively reduce vomitoxin levels in wheat with
low reject rates.
In recent tests vomitoxin was reduced from 2.6ppm to
1.3ppm with a reject rate of only 0.5%, and severely
contaminated wheat from the 1996 crop was cleaned
from approximately 12ppm to under 4ppm with a
reject rate of only 5%.
Applications for wheat
Quality Control and Sorting Capabilities:
The multi-chamber configuration of the Camas
separator provides the flour miller with unique
capabilities to maintain quality control and sort his
raw material input streams by important quality
characteristics such as protein and test weights. For
example, the output from the heavy impurities
chamber and the accepts from the number one
channel are consistently of superior quality.
One Camas owner takes these two streams and sends
them directly to a special bin to produce a premium
quality product required by one of his customers.
The combined savings from increased product
yield, lower operating costs, and lower air
requirements for dust control adds up to a
significant competitive advantage for owners of
the Camas separator, and a quick payback on the
machine, usually six to fifteen months!!
E. Weed Seeds & Grasses:The Camas separator has
proven its ability in the removal of weed seeds and
grasses. The Camas separator can remove offensive
grasses such as jointed goat grass, cheat grass and
morning glory seed, with a much lower reject of good
product than traditional equipment.
Corn Milling
Applications
VI. Corn Milling Applications
The Camas International fluidized bed small density separator is
revolutionizing the operations of major U.S. corn millers. By dramatically
improving product quality, increasing throughput capacity and yields the
Camas separator can lower both initial and working capital costs.
A. Cleaning of #4 Corn Grits: The most widely used application is in
cleaning the processed #4 grits to remove foreign material such as
ironweed, beeswings, germ, bran and heavy impurities. The Camas is
used as a final cleaner in this part of the process. One miller reports the
heavy impurities removal of the Camas separator had more stones being
rejected than their previous equipment. They were astonished at how
many stones and other heavy impurities their old equipment missed. With
the Camas separator our customers achieved their goals of lowering their
inventory of processed grits by
increasing throughput. Prior to the installation of our machine they had
4.0 million bushels of grits in storage. Within three months this inventory
of processed material was down to 1.2 million bushels. They said that the
Camas increased capacity and quality to meet their goals, and drastically
cut their working capital requirements.
Corn Cleaning
Applications
One of the millers that purchased our machine said that using the
Camas in this part of his process has given him a clear competitive
advantage in quality and capacity.
B. Front End cleaning:Another application is the original one for which
the machine was designed:. cleaning the whole corn coming out of the bin
into the facility. Because of its high capacity and accuracy, the Camas
separator far outperforms traditional equipment. In most cases the only
equipment required in the cleaning of raw corn out of the bin to remove
cob, foreign materials and heavy impurities is an air screener and the
Camas separator. This greatly reduces the amount of equipment and space
in the cleaning house of a corn mill. It also greatly reduces the amount of
dust control air required in this part of the process. Also, the Camas is
being installed after a series of Rotex machines to clean the rejects off
these machines. Instead of having to buy multiple gravity tables and destoners one Camas separator will do the job of four to six machines.
C. Grits, Germ, & Bran Separation:in the US. They will be using
multiple machines in the separation of fine grit, germ, bran and coarse
grit, germ and bran into separate streams. Because of the difference in
density between these products, our technology works very efficiently.
Using the Camas to do this separation eliminated the need for nine air
separators normally used to remove the bran. The accuracy and capacity
of the grit germ separation is much greater than traditional equipment.
Elimination of nine air cleaners in this process drastically reduced the
amount of air required for dust control
Cleaning Aflatoxin infected
grain
Aflatoxin, known as a powerful carcinogen, is a by-product of the
fungus Aspergillus Flavus which infects corn kernels nearing
maturity in the field and in storage after harvest when conditions
are right for propagation of the fungus. Because of health concerns
for both animals and humans, discovery of the substance in a corn
crop results in severe economic losses for producers.
In the past, mechanical removal of infected corn kernels was
impractical and uneconomical because traditional equipment relied
on differences in friction co-efficient or shape to effect separation.
Screens or sizing equipment are not effective because infected
kernels are approximately the same size as healthy kernels.
Gravity tables which rely on differences in friction co-efficient as
much as differences in specific gravity are rarely able to separate
products with density differences less than 13% while at the same
time rejecting up to 25% of favourable product.
The accuracy of the Camas density separator now makes
mechanical removal of Aflatoxin economical. During actual
operations on infected corn at Hondo, Texas in 1992, the Federal
Grain Inspection Service reported the reduction of the level of
Aflatoxin in corn from 180 parts per billion (PPB) to 16 PPB. Only
7.25 % of the corn was removed in the process, compared to over
25% reject from traditional gravity tables which were still unable to
lower the Aflatoxin level to less than 20 PPB.
Cleaning Aflatoxin infected
Grain
In the United States, corn for human consumption
cannot contain more than 20 PPB of Aflatoxin (in
Europe the limit is only 1 PPB). The limit in feed
corn for cattle is 300 PPB. Farmers with Aflatoxin
contaminated corn often have no alternative other
than selling their production at a sharply discounted
price or destroying their corn. Now, the Camas
separator can provide a profitable alternative for
producers and processors of corn. For example, in
Texas during August 1995 the Camas separator was
able to reduce Aflatoxin levels from over 600 PPB to
under 250 PPB, and from 80-100 PPB to less than
20 PPB.
Rice Cleaning
The Camas density separator is the best machine on the
market for cleaning and sorting rice. It has a broad range
of applications in the rice milling and processing industry
including:
General cleaning of foreign materials from rough
rice
Separation of underdeveloped grain from mature
rice
Separation of damaged and broken grains in
parboiled rice
Removal of bran and impurities remaining in
milled rice
Removal of stones, glass, and all types of heavy
impurities from both rough and milled
rice
Rice Cleaning
Reclamation of whole and broken rice from hulls
To test the cleaning capabilities of the Camas
separator, one of the largest U.S. food companies
placed exactly twenty small pieces of grey glass in a
large sample of their milled rice. Other cleaning
machines could not remove the glass, but the Camas
separator found and removed all 20 pieces.
Independent customer tests have proven that the
Camas separator is unparalleled for removing stones,
glass and metal from food commodities. The Camas
separator can operate with a far lower reject rate,
saving up to 25% more good product from rejects
than alternative equipment. The Camas Separator
can pay for itself in as little as six months! After
installing the Camas separator, a major California rice
miller stated that "This machine is excellent at
removing types of impurities that other equipment
could not!"
