TURNING CORNERS ON PACKINGHOUSE MACHINERY


The simple act of changing the direction of citrus fruit 900 on a packing line is
one of the most common sources of injury in packinghouses. The illustrations below are
from the final chapter by Dr. W. Grierson of a textbook in preparation edited by Dr.
E. B. Pantastico on postharvest handling of tropical and subtropical fruits.

A) illustrates the principle that a shear should not exceed an angle of 300 to
oncoming fruit. Also inside corners should be cut parallel to the shear so that the
opening is never less than the width of the delivery belt. Inspection reveals than an
amazing number of shears, corners, etc. have sharp, rough edges from nonsmoothed welds.
Every packinghouse manager and his best mechanic would do well to personally inspect all
seams, shears, etc. for rough edges and eliminate any questionable points.

B) illustrates the use of rods to lead citrus fruit from a belt to a wider conveyor.
Rod diameters are selected to move some fruit toward the conveyor and allow some to ride
over. This arrangement leads the fruit in the desired direction and prevents a build-up
against the shear. Another approach is to slope the delivery belt at the end to lead
the fruit in the direction of the conveyor.

Designing corners to minimize fruit damage. A) Transfer from one belt to another of the same or
lesser width. Gate-type shear should not exceed an angle of 30* to oncoming fruit. Inner corner is cut back
parallel to shear so that distance "X" is at least as wide as distance "Y". B) Transfer from a belt to a much
wider conveyor. The turn is eased by slender (ca. 5 mm) rods that ride on the belt. Inner corner is'again
cut back.

FFCSA HEALTH INSURANCE PLAN
The Florida Fresh Citrus Shippers Association has endorsed a group health plan
for employees of the Association's member organizations, and many of the members are
participating. The plan from Blue Cross & Blue Shield and a participating life
insurance company is especially written for the Association. It is designed for all
employees including harvesting crews in the hopes that it will encourage pickers to
remain with a citrus organization the required 30 days for coverage and thereafter to
continue as regular employees to retain their insurance coverage. This fringe benefit
is an important step by FFCSA members in recognizing the importance of loyal employees
and continuing programs of good employee relations.

SOOTHING LETTERS CITRUS FUNGICIDES ARE SAFE


The current anti-pesticide hysteria has resulted in our answering customer
complaints and inquiries to Florida packers concerning the use of pesticides and
"cosmetic" treatments' to citrus. Our offer to answer such letters still stands, and
the packer is provided with a copy of our reply. Among other things, we explain that
legal tolerances are set in parts per million (ppm); and that 1 ppm is equivalent to
the thickness of a postage stamp compared to the height of the Washington Monument,
or one penny in $10,000.

The most commonly used fungicide, thiabendazole (TBZ), also happens to be a
human medicine; for which purpose the dose is related to body weight. Medium-sized
oranges with a typical TBZ residue were used to calculate the two-day medicinal
dosage of TBZ normally given to a 50 lb. child. A 50 lb. child would have to eat
over 881,000 Ibs. or 19,579 cartons or about 19.6 semi-truck loads of TBZ-treated
oranges in order to get the equivalent of a medicinal dose. Oh yes, the oranges
would have to be eaten in two days peel and all!
