PACKINGHOUSE NEWS TTER

FULLY AUTOMATIC BAGGING OF ORANGES

For a year or more, the Automation Committee of the Florida Fresh Citrus
Shippers Association has sought to interest manufacturers in using the facil-
ities of the Citrus Experiment Station for testing and demonstration of items
of equipment, not already in use in the Florida citrus industry, that might
aid in packinghouse automation.

On May 28-29 the first cooperative test under this program took place.
The Dow Chemical Co. loaned the Florida Fresh Citrus Shippers Association the
prototype model of their "Zip-ZagR Bagger", supplied printed bags and paid all
incidental costs involved. The Citrus Experiment Station packing line was
modified to supply fruit from a PacRite counter (loaned by the American Machinery
Corporation). Two packinghouses, Haines City C.G.A. and Alcoma Packing Company,
-ach supplied 100 boxes of size 200 prepared 'Valencias' to be packed automatically
and shipped out in regular truck loads to market. Mr. Earl K. Bowman of the
USDA's Transportation and Facilities Research Division office at Gainesville did
time-motion studies of actual packing rates. Sixty visitors (mainly members of
the F.F.C.S.A, and their staffs) came to observe.

Thirty-two hundred bags were packed in all. Of these, time and motion
figures were obtained on 3,080 for an average packing rate of just under 15 bags
per minute of actual running time. Mr. Bowman has used these and other observa-
tions to arrive at preliminary project cost relationships. This study is included
as an appendix to this newsletter.

Excellent market reports were obtained from both loads (one to a major super-
market in the Detroit area and the other to a jobber in Knoxville, Tennessee).
The square-sealed, slack pack caused comment, but no real buyer resistance is
expected---the same customers buy radishes that way all the time.

This machine has gone back to Dow for further modification. The next machine
to be tested will be the W~ight Tilt-fill Bagger. Dr. W. Grierson has checked
its operation in the factory at Durham, N.C. and the Citrus Experiment Station
packing line has once again been modified to receive it. All arrangements are
being made through the office of Mr. W. G. Strickland, General Manager, F.F.C.S.A.

THE D.A.R.E. CITRUS CONFERENCE

The Citrus Conference, held as part of the D.A.R.E. (Developing Agricultural
Resources Effectively) program at Gainesville May 14-15, was attended by a high
proportion of the citrus industry's major executives. A paper on "Improving






July 10, 1968


Packinghouse and Processing Plant Technology and Efficiency" was given by
W. Grierson and CD. Atkins. Distribution copies were not prepared, but this
paper will be carried, in two installments, in the next two issues of Citrus
World magazine.

PACKINGHOUSE DAY

Our Seventh Annual Packinghouse Day Program will be held on Wednesday,
