Tomato products
By using this method no tomatoes but good ones can go through unless bad
ones are carelessly thrown into the center partition and every tomato
HAS to be picked up. Of course, some bad tomatoes are thrown into the
center carelessly, where they will remain unless taken out by the final
inspector, who is supposed to watch this. However, the number which are
thus thrown in are not great if the first four women on the belt are
trained as they should be—that is, to only throw those tomatoes in the
center which a hasty inspection shows are perfectly sound, and to leave
all doubtful ones pass by.
By this method each good tomato is only inspected once, which is not the
case with any of the other systems, and in that respect it is more
efficient. One good tomato is not picked up, looked at, and placed on
the belt again by a number of different sorters. When a tomato is picked
up by a sorter some disposition is made of it at once. If good it is
tossed in the center and is never looked at again except by the final
inspector. If bad, the good part is thrown in the center and the bad
allowed to remain on the outside, to be conducted to the waste barrel.
All the sorters except the first four can spend their entire time
working on tomatoes which need to have bad parts cut out of them.
The main objection which is made to the divided belt system is that the
first four women get careless and throw unsound tomatoes into the center
partition and they are never looked at again. However, if care is used
in the selection of these women, and a reliable sorter is placed at the
end of the belt to inspect the center partition before it leaves the
belt, such carelessness can be checked and held down to a minimum.
Another objection that is advanced is that there is the possibility of
partly good tomatoes going into the waste barrels due to the fact that
the women might not always keep up on them. In my experience with the
system I have had practically no trouble in this regard. If a long belt
is used, as many trimmers as desired can be put on, and the belt can be
slowed down or the rate at which it is fed slowed up if the tomatoes are
running particularly bad. Then, in extreme cases, it is always possible
to have someone go over the waste barrels before they are dumped.
An average grade of tomatoes can be handled quite rapidly by the divided
belt system. Some packers who have used it several seasons like it very
much, and an analysis of their product will generally show a low count
of molds, yeasts and spores, and bacteria. I understand, also, that
other packers that have used the method have discarded it.
