I, WILLIAM RICHARD CLARKE, of Anchor Biscuit Works, Limehouse, London, E.
Dog Biscuit Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention bas reference to machinery or apparatus for the torrefying of grain,
whereby the process of delivery to the oven and discharge therefrom is automatic,
thereby saving the labor necessary with existing methods of torrefying grain, at the
same time that the subsequent process of scouring by means of sand or other scouring
medium is rendered unnecessary.
In carrying out my invention I subject the grain to be torrefied to the action of
heated vapor until the necessary amount of moisture has been absorbed. The partially
dried grain is then placed in a feeding trough from which the grain is raised by means
of an elevator and discharged or deposited on to an iron plate, one end of which latter
has a constant tremulous motion imparted to it, in order that the grain may be
gradually and evenly deposited upon the hot travelling plates forming the bed or
flooring of the oven. A guide is provided over the vibratory plate above referred to,
to ensure the distribution of the grain to a uniform depth over the travelling plates
aforesaid. In this manner the layer of grain is conveyed through the hot air chamber
or oven, which should be heated to form 350 to 400 degrees Fahrenheit, whence the now
torrefied grain passes by means of an elevator to a cooling chamber. The grain when
cold being thoroughly cooked and ready for use.
The apparatus according to my invention is specially devised to allow of its
being adapted to and employed in conjunction with any type of oven having a
travelling Hoor or bed.

I, WILLIAM RICHARD CLARKE of Anchor Biscuit Works, Limehouse London, E.,
Dog Biscuit 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, reference being also had to the accompanying
sheet of drawings:
My invention has reference to improved machinery or apparatus for the torrefying
of grain, whereby the process of delivery from the hopper to the oven, and discharge
therefrom, is automatic; thereby saving the labor which is necessary with existing
methods of torrefying grain, in addition to which the subsequent process of
Scouring the grain by means of sand or other scouring medium is rendered
unnecessary.
In carrying out my invention I may, in the first instance, subject the grain to be
torrefied to the action of heated vapor until it has absorbed the necessary percentage
of moisture. The grain is then fed into a trough or hopper A from which it is raised
by means of an elevator B, and deposited upon an iron plate C, to one end of which
latter is imparted, by means of a crank and connecting rod actuated by the bevelled
wheels a, b, a vibratory or tremulous motion, to allow of the gradual and even deposi-
tion of the grain over the hot travelling plates D forming the bed or flooring of the
oven E.
A guide or guides F, arranged above the vibratory plate C, is provided for
the purpose of ensuring the distribution of the grain to a uniform depth over the
travelling plates D aforesaid. In this manner the grain is conveyed through. the hot
air chamber or oven E, which should be heated by any suitable means to a temperature
of from 350° to 400° Fahrenheit, whence the now torrefied grain is raised by
means of a suitable elevator, and conveyed to a cooling chamber; the grain when cold,
being thoroughly cooked and ready for use.
In order to vary the temperature of the hot air chamber, if desired, the door G
thereof, is connected by a chain d or equivalent to a suitable lever e, whereby said
door may be raised or lowered according to circumstances.
The improved apparatus according to my invention is specially devised to allow of
its being adapted to, and employed in conjunction with any type of oven having a
travelling floor or bed.
Having now particularly described and ascertained the nature of my said inven-"
tion and in what manner the same is to be performed 1 declare that what I
claim is
First. The improved apparatus for the torrefying of grain substantially as herein
described and shown in the accompanyin
drawings

page_text: Second. In the improved apparatus herein described for the torrefying of grain, the
combination with a trough or hopper of an elevator for the delivery of the grain to a
vibrating plate substantially as and for the purpose herein set forth and shown.
Third. In combination with the vibratory plate herein described and referred to in
the preceeding claim the employment therewith of a guide or of guides for ensuring
the even distribution of the grain upon the hot travelling plates substantially as set
forth.
