DESICCATING EGGS OTHER LIQUID MATERIALS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I LYDIA JANE CADWELL a Citizen of the United States and a resident of
Chicago Cook County State of Illinois U.S.A. Gentlewoman do hereby declare
the nature of said Invention for "DESICCATING EGGS
OTHER LIQUID
MATERIALS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
AND
My Invention relates to desiccating eggs and other liquid materials and in
apparatus therefor, the same constituting improvements upon the process and
apparatus described in Letters Patent No. 239,722, issued to me in the United
States of America April 5, 1881, and having for their object to secure a more
thorough mixture of the materials, a more homogeneous produce and facilitate and
expedite the operations.
In the Drawing the Figure is a part sectional elevation of sufficient of an egg.
drying apparatus to illustrate my Invention.
The outer casing A, has in it a carrier for the material to be dried. As shewn
said carrier is a band B, passing round the lower drum D, and upper drum D¹,
which with a moveable pan P, and tank T, are constructed and arranged in any
suitable manner, but preferably correspond to the like parts illustrated and described
in the Letters-Patent issued to me as aforesaid.
In connection with the travelling belt carrier I also use a disintegrating roller E,
which by contact with the material upon the surface of the belt crushes, agitates
and works and respreads the said material, thereby granulating or crystalizing the
Bame, reducing it to a uniform consistency and ensuring a more rapid desiccation.
The carrier, whether a drum or a belt as described, is revolved until a sufficient
amount of material is thereon, the pan is then lowered, and the carrier moved until
the material is in a viscid condition, as described in my aforesaid Patent.
In place of allowing the roller E, to be tur .ed by the movement of the belt B,
I prefer to impart a positive rotation to the roller E, by a driving belt b, as shown, or
otherwise, and in a direction the saine as that in which the belt B, travels, thereby
ensuring a more effective working and breaking up of the material.
At one side of the belt B, revolves a second carrier, shown as consisting of a
drum F, and within the belt revolves another drum G, the carrier F, being situated.
with its edge opposite and at a short distance from the carrier B, so that by a lateral

page_text: movement of the druin G, the outer face of the belt carrier will be brought in
contact with the carrier drum F.
The carrier F, is driven by a driving belt c, or otherwise, in a direction contrary
to that in which the carrier B, travels, the result being that the material carried
by the belt B, is transferred to the drum F, where it is further worked and dried
by the contact of a disintegrating roller E', turning in the same direction as the
drum.
A knife, or a series of knives or scrapers S, is arranged near the periphery of
carrier drum F, so as to receive therefrom the thoroughly worked and dried
material left upon the face of the drum, after the action of the disintegrator E', the
material uncovered by the knife falling upon a travelling belt H, which conducts
it to the drying chamber for final drying.
By this double working of the material it is reduced to a more homogeneous
condition, the albumen is thoroughly incorporated, a better granulation is secured
and the desiccation effected more rapidly.
It is most desirable to prevent too quick a hardening of the material upon the
surface of the belt B, and also to have the product as thoroughly dried as possible
before it is deposited upon the carrier belt H, I therefore direct the products of
combustion or heated air from the furnace through a flue x, first upon that portion
of the product which is in the act of removal by the scrapers S, thereby drying
the product, the gases being then diffused through the chamber and acting more
slowly upon the material carried by the belt B, and then passing to an outlet y,
below the inlet x, on the opposite side, I thus apply a strong heat to that portion
of the material which has been thoroughly worked and in a nearly dry condition
änd a diffused and reduced heat to the fresh portion of the material which must be
heated slowly in order to prevent the albumen from being solidified before being
thoroughly incorporated with the other portions.
In some instances the travelling belt H, may be passed directly around the
carrier drum F, the knives S, simply loosening the material upon the belt, I
however prefer the arrangement shown and above described.
Any suitable means may be employed for driving the various drums or rollers
and the disposition of the same within the drying chamber may be varied according
to circumstances.
It will be obvious that to secure a more thorough and effectual breaking up and
disintegration of the films of material, the number of carriers is increased, two or
more drums or carriers E, being employed. By this means the material is fed
continuously.
I do not limit myself to the precise construction and arrangement of parts
shown on the Drawing as these may be varied according to circumstances.
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
(1.) The within described improvement in treating eggs and other liquid or
semi-liquid substances, the same consisting in depositing the material upon a
moving carrier, subjected to heat, working the material upon said carrier, then
transferring the worked material to and working it upon one or more additional
carriers and then detaching it from the latter and subjecting it to a final drying
process, substantially as specified.
(2.) In the treating of eggs and other like substances, working the material first
upon one, and then upon another carrier under the influence of heated gas-s con-
ducted from the furnace first to the last carrier and then to the first, substantially as
specified.
(3.) The combination in a desiccating apparatus, of two or more carriers and two
or more disintegrators and means for bringing the first carrier after the material is
sufficiently worked in contact with and transferring it to the second, substantially
as specified.

page_text: (4.) The combination with the carrier B, of a disintegrating roll and means for
revolving the latter positively in the same direction as the carrier, substantially as
specified.
(5.) The combination of the carriers B, F, scrapers S, and gas inlet x, arranged
adjacent to said scrapers and outlet y, below the inlet and at the opposite side of
the apparatus, substantially as specified.
