We, HEINRICH HENCKE, JOHN PALM, and ERNST SEELIG dealing in partnership
as "Heinrich Hencke & Co." Manufacturers, in Darmstadt, Germany, do hereby
declare the nature of our said invention to be as follows:-
The object of this invention is an improved form of evaporator for treating
products when in a liquid state.
-
In preparing products in a liquid state it is necessary to evaporate as quickly
as possible a certain per centage of water in the same before bringing them upon
the rolling machine.
Our improved evaporator is in the form of a circular basin and is so constructed
as to be moved horizontally by a vertical shaft with which it is suitably connected.
The hot air is lead under the evaporator or basin by means of channels isolated
from each other. In order to produce a solid stuffing, and at the same time retain
an easy turning of the evaporator or basin, rails (preferably U shaped) and filled
with sand, are placed upon the walls of the channels and into which enters an
iron hoop.
.
•
To facilitate the turning of the evaporator or basin the outer and inner curbs of
the same are supported by wheels which are placed at regular distances upon the
peripheries.
•
At one side of the evaporator or basin are two openings, parallel to, and
adjoining each other, through one of these openings the hot air enters and after
traversing round under the evaporator or basin, discharges itself at the other
opening, the liquid material which has to be dried being brought upon the
evaporator or basin (near the first opening) in thin and regular layers and by
means of any suitable arrangement.
During the turning of the evaporator water is rapidly evaporated by means of
the hot surface and the material under treatment becomes thicker and more
disposed to burning, but at the same time and in the same proportion as the
material becomes thicker the surface becomes cooler so that after one completed
revolution the material is much evaporated without being burnt.
The evaporated material is removed by means of a scraper or any other suitable
arrangement and the evaporator or basin may be provided with a stirring arrange-
ment for the regular distribution of the material which has to be dried.

page_text: The liquidous material having been evaporated and dried to a certain extent
as above described it is brought upon the rolling machine described in Letters
Patent No. 6768 of 1884 where it is dried entirely.
Instead of this rolling machine which is composed of several pairs of rollers
rotating towards each other and placed above each other the following arrange-
ment may be used→
A large moveable cylinder heated by steam or air from the inside, on the
periphery of which a number of small cylinders (either heated or not heated)
move in opposite directions.
The material is brought upon the cylinder where it is at once caught by the
first roller which distributes it regularly and presses it out; the pressing and
evaporating is effected under the second and third rollers and so on in the same
manner as has been described in Patent No. 6768 of 1884-In this arrangement
however the material remains for a longer time in contact with the bot cylinder
surface and thereby a better effect is produced.
Scrapers of the form of knives are pressed by weights or otherwise against the
roller and remove the material from the cylinder; the material is then gathered
together and eventually brought upon another drying apparatus..
It is obvious that several of such roller systems may be used and placed one
beside the other or over each other and that they may be connected by means of
transport cloths or any other suitable arrangement.

We HEINRICH HENCKE, JOHN PALM, and ERNST SEELIG, dealing in partnership
as Heinrich Hencke & Co., Manufacturers in Darmstadt, Germany, do hereby
declare the nature of our said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The object of our invention is to manufacture an improved form and arrangement
of evaporating apparatus, for drying or reducing the moisture in fodder derived
from the refuse of breweries or any other products, when in a liquid or semi-fluid
state, previously to and in order that such products may be compressed or otherwise
treated, and rendered suitable for packing or transportation; and our invention is
intended to be used, though not exclusively, in connection with certain apparatus
described in the Specifications of certain Letters Patent granted to us No. 67688.
And in order that our said invention may be more particularly described and
ascertained, reference is hereby made to the accompanying drawings.
Fig. 1 is a sectional elevation of our improved drying apparatus: Fig. 2 is a
plan of the same, and Fig. 3 is an elevation of our improved rolling apparatus ;
being an improvement for some purposes, of that described in No. 67684
The drying apparatus shewn in Figs. 1 and 2, consists of a metallic structure, in
the form of a frustum of a cone, which is mounted upon anti-friction rollers L L,
in order that it may be caused to revolve upon its own centre without much
friction, its revolution being effected by any suitable motive power, applied in any
convenient manner.
Any convenient number of such supporting wheels L may be employed, eight
being shewn in the drawings.
J is a furnace suitably erected in masonry, the heated air from which is led in a
circular direction through the flue Z under the apparatus to its exit at Z³, from
whence it may pass to an ordinary chimney to produce a suitable draught.
Upon the walls at M annular iron channels of U-form are built-These are filled
with sand, and annular hoops, tongues or rings M' dip into these channels, and
thus form air-tight joints, whereby the escape of the heated air is prevented, as the
apparatus rotates.
A is an outlet pipe for the steam, and, through this outlet, passes, at 63, the steam
formed upon the evaporating plate o; the steam being either drawn in an upward
direction (such as, for instance, by means of an exhauster) or being conveyed partly
through the slot or opening formed between conical plates b b', below the plate b,
and partly through the slot or opening formed in the latter towards the highest
slot or opening in the pipe A.-Surrounding the pipe A an annular receiver a is
fitted into which the liquid required to be heated is placed and from whence it
descends, as shewn. As the shelves b and b' are formed, with inclined surfaces
and are completely closed at their peripheries by means of the wall D, the liquid
runs down and falls through the openings in the plate b to the shelf b¹. These

page_text: •
shelves bb¹ are heated by the steam, and hence the liquid flowing upon the
plates 661 is subjected to a preliminary heating, passing subsequently through the
collecting channel 62, whence it is conveyed to the evaporating plate O through
the pipe 6º.
As the apparatus revolves, the moisture is evaporated, and the partially or wholly
dried material arrives at P where the flue is much cooler, and a scraper or other
suitable device for removing the material is there placed, as shewn at P in Fig. 2.
After the material has been removed from the apparatus shewn in Figs. 1 and 2,
it is sometimes placed upon a cylindrical machine of the form shewn in No. 6768%;
or instead thereof, the rolling machine shewn in Fig. 3 may be used, for the purpose
of drying and pressing the material and preparing it for use.
In Fig. 3 R is a large cylinder, which is caused to rotate on its centre by any
suitable means, and is heated by steam or hot air. Small cylinders Z Z Z3 Z4 Z³
Ze are fitted as shewn. These cylinders may be also heated (but not necessarily)
by steam or hot air, and are caused to rotate by contact. e is a hopper into which
the material is placed, and from whence it passes to the surface of the cylinder and
rollers. The rollers distribute the material evenly upon the cylinder R, and at the
same time press the same; the heat and pressure being arranged to suit the degree
of dryness required; and the material may be kept in contact with the cylinder R
for a longer time than is usual with the rollers described in No. 676884.
Scrapers may be placed at F, having knife edges, and actuated by levers and
weights, for scraping any material from the cylinder which may adhere thereto.
It is obvious that a series of rollers may be used, when necessary; the material
being carried from one to the other by means of bands, webs, cloths, or other
equivalent devices.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The method of and means and appliances for making or producing fodder
from the waste products arising from manufacturing operations, substantially as
herein before described and shewn on the drawings.
2. The general construction combination and arrangement of apparatus together
constituting our improvements in the method of and apparatus for making fodder
from certain waste products, substantially as herein before described and shewn on
the drawings.
