Improvements in the Preparation of Oats used in the Manufacture of
Oatmeal, Oat Flour, and Rolled Oats or Flaked Oatmeal.
I, WILLIAM INGLIS, The Midlothian Oatmeal Mills, Bonnington, Leith, N.B.,
Manufacturer of Oatmeal, Oat Flour, and Rolled Oats, or Flaked Oatmeal, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the preparation of oats used in the
manufacture of oatmeal, oatflour, and rolled oats or flaked oatmeal and consists
of a system of steam piping arranged to introduce steam into the oats after being
thoroughly cleaned and immediately before the oats pass into the drying kilns.
The advantage of this treatment is to cause a considerable amount of steam
to be generated in the earlier stage of drying, the grain, this causes the grain after
being well dried to shell or hull much more easily and brings about a considerable
saving in waste, as oats that have been thus treated come out of their hulls of
shells quite freely and less severe hulling or shelling is necessary.
The flavour of the oatmeal, oatflour, and rolled oats thus treated is greatly
improved and further the natural starch is considerably altered and is much more
easy of digestion. The keeping properties of the products are also improved.
The mode of application of the steam to patent kilns or vertical self acting kilns
of any kind consists in having the steam introduced into the feed pipe or spout
or worm conveyor supplying the kilns. For this purpose I employ small nozzles
to inject the steam into the body of oats while passing down the supply grain
spouts into the kilns, which spouts etc. are always kept full of oats, the amount
of steam being regulated by means of suitable valves.
With the old style of flat head kilns or American pan kilns, the steam may
be applied as above described or by perforated pipes situated under the kiln head
or bed plate or wire cloth, or under the bottom of the pans, in which case the
steam after having sufficiently moistened the oats is turned or shut off, to allow
the oats to be dried in the usual way.
The products from oats treated in accordance with my invention may be called
or styled steamed oatmeal, oatflour etc.

page_text: 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:
This invention relates to improvements in the preparation of oats used in the
manufacture of oatmeal, oatflour and rolled oats, or flaked oatmeal and consists
of a system of steam piping arranged to introduce steam into the oats after being
thoroughly cleaned and immediately before the oats pass into the drying kilns.
The advantage of this treatment is to cause a considerable amount of stean
to be generated in the earlier stage of drying the grain; this causes the grain after
being well dried to shell or hull much more easily and brings about a considerable
saving in waste, as oats that have been thus treated come out of their hulls or
shells quite freely and less severe hulling or shelling is necessary.
The flavour of the oatmeal, oatflour, and rolled oâts thus treated is greatly
improved and, further, the natural starch is considerably altered and is much
more easy of digestion. The keeping properties of the products are also improved.
But in order that my said invention may be more readily understood and easily.
carried into effect I will proceed to describe the same with reference to the accom-
panying drawings in which
Fig. 1 is a cross section of a patent kiln and
Figs. 2 and 3 similar views of flat head kilns shewing my improvements applied
thereto.
Referring to Fig. 1 of the drawings I arrange within the feed pipe or spout A
supplying the kiln, a coiled pipe B which is provided with a number of small
nozzles 6 so that steam is injected into the body of oats whilst passing down the
said supply pipe or spout into the kilns. The spout A is always kept full of oats
and the amount of steam regulated by means of a suitable valve C.
The oats then pass around the casing D, which is heated by hot air forced by
the fan d from the furnace d¹, where they are thoroughly dried, the steam and
moisture making its escape through the openings E.
The dried oats then pass through the outlet e and are led by a worm conveyor
to the mill, to be treated in the usual
way.
With the old style of flat head kilns as shewn in Figs. 2 and 3 the steam may
be applied in a similar manner to that first described such as by a straight length
of pipe F situated below the spout, the nozzles of which protrude therethrough;
or by a coiled pipe. Or the nozzles may inject the steam through the casing G.
of the worm conveyor feeding the kiln, when such is employed.
Or when the kiln is fed by manual labour a number of lengths H of piping
connected with a steam box h supplied by a main steam pipe h¹, is or are arranged
below the woven wire cloth or perforated metal plates forming the kiln floor or
bed, so that the steam escaping from the nozzles can penetrate into the oats, the
amount of steam being regulated and cut off when the oats are sufficiently moistened
by suitable valves in all the various forms described.
In American pan kilns steam may be applied in a similar manner to either of
the methods described.
The products from oats treated in accordance with my invention may be called
or styled steamed oatmeal, oatflour etc.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I'
claim is:-
-
1. The introduction of steam into oats in the manufacture of oatmeal, oatflour,
and rolled oats or flaked oatmeal, after being cleaned and immediately prior to
being dried, substantially in the manner as and for the purposes hereinbefore
described and shewn in the accompanying drawings.
2. In patent kilns for drying oats in the manufacture of oatmeal, oatflour,
and rolled oats or flaked oatmeal, the employment of a coiled steam pipe situated
within the feed pipe or shute having nozzles arranged to inject steam into the oats

3. In flat head or American pan kilns, for drying oats in the manufacture of
oatmeal, oatflour, and rolled oats or flaked oatmeal, the employment of a steam
pipe or pipes, coiled or straight and arranged within or below the supply shutes
or below the kiln floor, bed or pan, having nozzles arranged to inject steam into
the oats, substantially as and for the purposes herein before described and shewn
in the accompanying drawings.
