Improvements in Apparatus for Drying, Roasting, or Steaming by
Means of Hot Gases.
1, FERDINAND GOTHOT, of Mulheim-on-the-Ruhr, Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows;-
The apparatus of this invention comprises an outer casing within which is fixed
a drum for the reception of the goods to be dried or steamed or roasted.
Between the top of the casing and the drum, which may be fixed, or adapted
to rotate, is fixed a perforated partition by which a horizontal passage is formed
which leads into a vertical passage and this latter downwardly into the drum at
one end thereof. The other end of the drum is provided with an outlet through
a pipe formed in one piece with the casing and leading to the outside of the
apparatus. The hot gases enter through an aperture at the bottom of the casing
pass upwards circulating between the drum and casing, then through the per-
forated partition and vertical passage and along the same into and through the
drum to the outlet pipe.

Improvements in Apparatus for Drying, Roasting, or Steaming by
Means of Hot Gases.
I, FERDINAND GOTHOT, of Mulheim-on-the-Ruhr, Germany, Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement;-
The apparatus of this invention is more especially designed for drying or
torrefying cereals and other granular goods and the object of the invention is to
provide an apparatus for this and the like purposes in which the heating gases
are fully utilised by conducting them first around and then through a drum con-
taining the goods to be treated.
The apparatus consists substantially of an outer casing within which is placed a
drum for the reception of the goods to be treated and which casing is provided
with channels for uniformly distributing the heating gases around and then lead-
ing them through the drum.

pipe by which the used heating gases are discharged from the apparatus.
e is a
The heating gases enter the apparatus through an aperture f at the bottom of
the casing, pass, as indicated by the arrows, around the drum, then through the
openings d and channels c, c¹, to the interior of the drum from which they are
discharged at e.
The openings d are uniformly distributed over the partitions g, gl, to cause
a uniform flow and distribution of the gases over the entire surface of the drum
and as the gases are always kept in close proximity to the drum and finally pass
through it before leaving the apparatus, cooling of the drum is prevented and
loss of heat obviously avoided.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
In apparatus of the kind referred to a drum casing in which are arranged per-
forated partitions forming horizontal and vertical channels for the purpose of
uniformly distributing the heating gases and leading them into or through the
drum, substantially as described and shewn.
