Application July 1, 1935, Serial No. 29,276
5 Claims. (C1. 34-12)
This invention relates to driers and in par- spaced guide rails 8, supported by the vertical
ticular to a continuous drier wherein the material to be dried is carried on an endless support and during the course of the drying opera5 tion is turned over by means of a rabbling device.
In general the object of my invention is the
provision of a drying chamber through which a
bed of discrete particles to be dried is passed,
and which is provided with a plurality of spaced
frame members 2 and by additional superstruc
ture as indicated in Figure 1. The material to
be dried is fed in a wet condition to the endless
conveyor 5 by means of a hopper 9, supported 5
above the endless conveyor by means of suitable ,
superstructure. Secured to the superstructureyat
the opposite end of the drier is a hopper H into
which the dried material is discharged. Mounted
10 discs which serve to turn over the particles forming the bed, and thereby present. new surfaces
to the drying medium.
intermediate the ends of the upper compartment 10
of the heating chamber l and between the lateral
walls l2 of the chamber, is a shaft l3. This
More speci?cally the object of the invention
is the provision of a rabbling device comprising
15 two sets of discs mounted on a shaft, the members of each set being parallel and‘disposed lntermediate the members of the other set, the discs
of one set being disposed at an angle with resp'e'ct
to the discs of the other set.‘

to be driven by means of a pulley l5 secured to
one or its ends and‘ which in turn may be driven
by means of a motor Ii carried by the super
structure of the device as shown in Figure 1.
