some problem, it is herein illustrated and discussed pri
marily with reference to the ordering of tobacco, i.e. the
treatment of tobacco to ensure that it has a desired mois
ture content.
In ordering tobacco, the tobacco is conveyed through
a chamber where the air is maintained in a moisture
laden state and circulated through the conveyed tobacco.
As a result, considerable free water is unavoidably pres
ent within and on the outer surface of the chamber. To
catch such water, it is the practice to erect the chamber
within the con?nes of a stainless steel pan on the ?oor
and to connect the pan to the drain.
Such an arrange
ment has the serious drawback that, when leakages de
velop, due to corrosion or otherwise, repairs are di?icult
and expensive and usually require that the apparatus be
shut down for an objectionably long interval.
The principal objective of the present invention is to
provide apparatus in which the drainage of free water is
controlled by means that are easily installed and repaired
so that the apparatus will not only have a long life, due
to more e?icient water drainage, but also can be repaired
without any objectionable interference with production.
In accordance with the invention, this objective is at—
tained by providing apparatus having a chamber in which
near to one edge of the roof 19 and have their lower ends
interconnected by a bottom rail 21. Between their ends,
20 the supports 20 are connected to appropriate ones of the
supports 16 at the side 17 by braces 22 and at the side
18 by transverse, braced members 23.
The upper course of a conveyor 24 passes through the
chamber 15 and is supported by sprockets 25 at each end
25 thereof although only those at the outfeed end of the
chamber 15 are shown. As may be seen in FIG, 2, the
sprockets ‘25 have their shaft 26 journalled in bearing
brackets 27. The conveyor 24 may be of any type and is
shown as having tobacco retaining side Walls ‘28. Se
cured to the proximate faces of the supports 20 and the
supports 16 in the side 18 are transversely alined ?anged
members 29 which serve as tracks for the conveyor rollers
39.
Certain of the sections have motor driven blowers 31
mounted between the supports 26 and the supports 16
in the side 17. Each blower 31 has its intake opening
into the space below the upper course of the conveyor
24 and its outlet disposed to discharge air against the
roof 19 where there are steam heating pipes 32.
The
heated air passes downwardly through the conveyed to
