At the end of from ten days to three weeks, the equalizing process
should be over, and the layers ready for further packing. When the boxes
are removed, it will be found that the majority of those raisins which
had been too moist or underdried have dried sufficiently, while on the
contrary the overdried raisins, as well as the formerly brittle stems,
will have acquired sufficient moisture to enable the packer to
manipulate them without risk of breaking the bunches. The raisins should
be pliable, and stand moderate pressure without cracking or breaking.
But while equalizing is an important operation, and one which we cannot
dispense with, it is always to the grower’s interest to so dry his
raisins previously that they will require as little equalizing as
possible, as even the most carefully sweated raisins which have once
been overdried will never afterwards equal those which were at once
properly dried in the field. The overdried raisins will always have a
tougher skin and be inferior in color; but on the other hand they will
keep better than raisins which have been dried less.
_Grading and Weighing._--The next step after the raisins have been
equalized is to remove them to the grading tables. This should not be
done by dumping the contents of a sweatbox on the table, as in this way
but very few of the real choice bunches are saved for the packer. If,
however, the raisins have been placed carelessly in the boxes, without
sufficient or perhaps without any manilla papers between the layers, the
only way is to dump out the contents. By first placing the sweatbox on
the long side, and then turning it over, the raisins are but slightly
disturbed. But to get these out afterwards from the chunk is the great
difficulty, and many bunches must necessarily be broken. If, again, the
raisins have been carefully handled and consigned to the sweatboxes,
with four papers in every box, not counting in the top cover, the care
and handling of the sweatboxes will be much simplified. The sweatbox is
then placed alongside of the grading table, and each layer with its
paper is lifted out carefully, and placed on the table. The assorting is
now to begin. The bunches are taken up one by one, all inferior berries
are clipped out, all soft ones are separated and placed in a box by
themselves to be further dried. As each bunch is examined and cleaned,
it is put in one of the weighing trays resting on small scales at either
end of the table, and, when the scales indicate that five pounds of
raisins are in the tray, the latter is removed to the packing table.
