Experimental Citrus Feed Mill

Citrus Experiment Station
Lake Alfred, Florida

An experimental pilot plant completed in November of 1963 has been
placed in successful operation and shows promise as an invaluable tool in
current search for new by-products. The facility is housed in a 30 by 40-
foot steel building and provides the equipment and opportunity to manufact-
ure dried citrus pulp and meal under closely controlled conditions at the
rate of One 100-pound bag per hour.

The unit is unique in being able to produce a dried product within a
matter of push button style. Screw conveyors and troughs have
been fabricated from stainless steel to avoid problems of contamination and
corrosion in handling wet citrus peel. The furnace is gas-fired and coupled
to a triple-pass direct-fired drier designed to evaporate 600 pounds of
water per hour. This is the equivalent of being able in one hour to convert
the peel from 20 boxes of citrus to dried citrus pulp. The unit is adaptable
to many needs be it cattle feed, citrus seasoning for bakery goods, an
official pesticide residue sample, or a pectin product.

Currently one of the important problems facing this and other agricul-
tural industries is the determination of residues of pesticides that remain
after harvesting. This paramount need for accurate residue information and
samples for establishing tolerances was one of the motivating forces in
providing a feed mill at the Citrus Experiment Station. It must be remembered
that citrus pulp has been produced commercially for almost 22 years.

Prior to the construction of this feed mill, an official citrus pulp
sample required the peel from 60 to 70 boxes of fruit, a great deal of
technical assistance from the Experiment Station, and the generous coop-
eration of the Kuder Citrus Pulp Company. Today, this new mill offers
that important opportunity to prepare samples that can duplicate industry
to the nth degree and with all variables under control. In a recent trial,
excellent citrus pulp samples were prepared from 12 box lots of grapefruit,
with every indication being that a 10-box lot would be sufficient. There
was in the troughs of this unit a peel hold-up equivalent to two boxes of
fruit which was recovered adequately with a commercial 1 horsepower
vacuum cleaner. This peel became available for further processing, but
almost as important was the greater simpleness of the clean-up operation.

Beyond the immediate need of this equipment to prepare citrus pulp
samples for residue analysis are the needs to effectively dry citrus peel
without loss of xanthophyll content, to prepare economically dried citrus
peel for the baking, candied peel, and seasoning industries, and to seek
other new products that can gross more than 2.5 cents per pound.


The experimental citrus feed mill, which you will visit today, is
a reality because of the interest and support of the Citrus Processors'
Association and.the Florida Canners' Association. In addition to funds,
recommended by the State Board of Control, and made available to this
Station for this purpose by the Florida State Legislature, financial
assistance also was provided by the Florida Citrus Commission. Consider-
able time and effort on this project also was expended by Mr. Frank L.
Holland. Mr. Dan B. Vincent, who designed, built, and installed the
equipment, was also very helpful in many ways. The assistance of Mr. Fred
E. Clayton, Zone Engineer for the State Board of Control, expidited greatly
the construction of this pilot plant. This opportunity is taken to sincere-
ly thank these organizations and individuals for their support and assist-
ance, as well as all others who helped in various ways.
