Tomato products
By having the tomatoes thoroughly clean, with no mud and scarcely any
mold adhering to the surface when they drop on the sorting belt, the
amount of sorting required is not only greatly lessened, but the spots
of black rot and other forms of decay show up prominently on the
surface.
It is important that the reel deliver the tomatoes to the sorting belt
at a uniform rate, which is seldom done when the crates are dumped into
the reel without any system of timing them. At present a hopper for
feeding the reel is being experimented with, and it is hoped that it
will be an improvement over the uncontrolled system that is now used.
The chief objection made to the reel cylinder is that when tomatoes are
overripe, having been shipped a long distance, or held at the factory
for a day or two, the rubbing action of the wire on the tomatoes, and of
the tomatoes against each other, is too severe, and considerable tomato
substance is lost by being forced down through the wire mesh by the
sharp sprays of water from overhead. The loss in this case is not nearly
as great as would be imagined, and what tomato substance is thus lost
should be discarded anyway, as it is so soft that in all probability the
fiber is permeated with growths of mold, yeasts, and bacteria, which no
amount of washing would eliminate.
Water Bath With Compressed Air
The reel washer is not so common in the east as in the west, and the
reason is, as previously stated, that during the greater part of the
season at least, tomatoes grown on loose, sandy soil can be washed
satisfactorily by other devices which are less cumbersome and can be
more easily rigged up. One of these devices which is in satisfactory
operation is a shallow water bath through which the tomatoes pass on a
chain carrier, and in which the water is kept “boiling” (that is, it has
the appearance of boiling) by compressed air which is forced into the
water bath through small pipes, and at a number of different places. The
tomatoes are thus bounced around and knocked against each other in a
very lively manner and receive a thorough cleansing. It is very
doubtful, however, if this device would give such good results on
tomatoes that had clay baked hard on the surface, or on those which had
mold deeply imbedded in cracks at the stem end.
