Tomato products
It is always advisable to wash the tomatoes before sorting them, as it
makes the sorter’s work so much easier. After the tomatoes leave the
sorting belt they can pass under a few strong sprays which will put on
the finishing touches. Warm or hot water is sometimes used in washing
tomatoes, but cold water does the work just as well. Neither will
accomplish much more than wetting the surface unless the tomatoes are
agitated. Some devices which I have seen are almost worse than nothing,
as they merely consist of a long water bath through which the tomatoes
are conveyed by means of a large worm or helicoid. The tomatoes are not
only washed insufficiently, but are contaminated by rubbing against the
surface of the worm, which soon becomes coated with a film of mold, and,
being enclosed in a cylinder, this worm cannot be cleaned as it should
be. It is essential that every part of the equipment with which the
tomatoes come in contact be readily accessible to the brush and the
steam hose. Mold accumulates very rapidly, clings very tenaciously to
the surface on which it grows, and a damp surface in a dark place is
ideal for its growth.
Plain Sorting Belt
The type of sorting belt used most commonly is the ordinary plain wire
or metal belt 18 to 24 inches in width and about 10 to 12 feet in
length. Canvas belts are also used quite frequently, but the packer can
now obtain wire belts of such strong, sturdy construction that they give
scarcely any trouble and are very satisfactory in every way. Eighteen to
twenty inches has been found to be about the best width.
Number of Sorters
The number of sorters which should be employed on each belt depends upon
whether they are going to do both the inspecting and trimming, or the
inspecting alone, and also upon the rate at which the tomatoes are fed
to the belt, the length of the belt, and the quality of the fruit. Some
pulp makers prefer to feed the belt at a uniform rate regardless of the
quality of the fruit and to vary the number of sorters, employing about
14 or 16 to a belt when the quality is poor, and about half that number
when the tomatoes are almost entirely sound and need very little
trimming done to them. Others prefer to use the same number of sorters
and trimmers on the belt all the time and to vary the speed of the belt
according to the quality of the fruit, using a variable speed
transmission for this purpose. When running on solid fruit, with very
little decay, the maximum speed can be employed, say 40 feet per minute,
and when running on stock that is not so good the speed can be decreased
to about 10 feet per minute.
