Salt, and like Substances.,.
I JAMES BUCHANAN Junior of Caledonia Foundry Brasenose Road Liverpool, in the
County of Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
The object is to provide improved and efficient apparatus for drying and
granulating Sugar, Salt and like substances.
The invention relates to apparatus in which the Sugar, Salt, or liko substance is
caused to travel through a rotary cylinder or cone having an internal heating cylinder
or cone and consists :-
First. In constructing the internal and external cylinders or cones or either of them
of metal corrugated, fluted or grooved, longitudinally, transversely or spirally.
Second. In providing the internal and external cylinders or cones or either of
them with discs, plates or shelves secured in position, longitudinally, transversely,
diagonally or spirally.
Third. In carrying the apparatus on hollow gudgeons secured to the internal and
external cylinders or cones and free to rotate in suitable bearings.
Fourth. In fitting the internal cylinder or cone with a pipe secured to and rotating
with one of the hollow gudgeons.
Fifth. In providing the inlet end of the external cylinder or cone with a shield and
deflector secured thereto and with an inlet way for the substance to be dried and
granulated.
Sixth. In fitting the hollow gudgeons with stuffing boxes and inlet and outlet
pipes for steam, heated gases or products of combustion and with driving gear for
giving rotatory motion thereto at the required speed.

I, JAMES BUCHANAN Junior of Caledonia Foundry Brasenose Road Liverpool in
the County of Lancaster Engineer 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 object is to provide improved and efficient apparatus for drying and granulating
Sugar Salt and like substances.
The invention relates to apparatus in which the sugar, salt or like substances is
caused to travel through a rotatory cylinder or cone having an internal heating
Cylinder or cone and consists
First. In constructing the internal and external Cylinders or cones or either of
them of metal corrugated fluted or grooved longitudinally transversely or spirally.
Second. In providing the internal and external Cylinders or cones or either of them
with dises or with plates or shelves secured in position longitudinally transversely
diagonally or spirally.
Third. In carrying the apparatus on hollow gudgeons secured to the internal and
external Cylinders or cones and free to rotate in suitable bearings.
Fourth. In fitting the internal Cylinder or cone with a pipe secured to and rotating
with one of the hollow gudgeons.
Fifth. In providing the inlet end of the external Cylinder or cono with a shield
and deflector secured thereto and with an inlet way for the substance to be dried and
granulated.
Sixth. In fitting the hollow gudgeons with stuffing boxes and inlet and outlet pipes
for steam heated gases or products of Combustion and with driving gear for giving
rotatory motion thereto at the required speed.

carrying standards. 2. Internal Cylinder corrugated transversely and carried by
hollow gudgeons 3, 4, in bearings in the standards 1. 5 External Cylinder formed
with a plane surface and carried by arms 6 cast with or screwed to the hollow
gudgeons 3. The external Cylinder may be transversely corrugated as well as the
internal Cylinder; or the external cylinder may be transversely corrugated, and the
internal Cylinder have a plain surface, or the corrugations on either or both of the
Cylinders may be either diagonal or spiral or they may be as shown in Figure 3
fluted longitudinally. Instead of corrugations either the internal or external Cylinder
or both may be provided with discs as shown in figure 4, or with longitudinal or
spiral plates or projections as shown in figures 5 and 6; or the plates or projections
may be placed transversely or diagonally. The discs or plates would be applied to
the internal surface of the external Cylinder. 7 Indicates shoots which aro secured

page_text: between the arms 6 as shown in figure 7 to ensure rapid delivery of the dryed and
granulated sugar or substance. The bearing in the Standard carrying the receiving
end of the Cylinders is higher than that carrying the delivery end so that the
Cylinders are inclined from the receiving and delivery end and the sugar or
substance to be dryed and granulated is freely carried forward by the rotation of the
Cylinders when cones are used both bearings may be the same height. Tho
corrugations, discs, or plates assist the carrying forward of the substance, and prevent
such material from massing or balling: they also serve to prevent tho substance from
falling off the inner Cylinder too freely when dropped thereon by the rotation of the
apparatus and so subject it for a sufficient length of time to the heated surface of the
inner Cylinder as to ensure rapid drying. The hollow gudgeon 4 is fitted with a dip
pipo 8 to carry off water of condensation from the Cylinder 2. 9 Stuffing box and
inlet for Steam or heating gases to the Cylinder 2. 10 Stuffing box and outlet for
Steam or heating gases from the Cylinder 2. 11 Worm wheel and driving gear.
12 belt pulley made coned, or with steps so that the speed of rotation may be easily
altered. 13 deflecting plate secured to the external Cylinder to prevent sugar or
substance being treated from falling out of tho receiving end thereof. 14 Shield
secured to the standard 1 to prevent gases and moisture driven off from the Sugar or
material being dryed and granulated from leaving the Cylinders. 15 feed hoppers
passing through the Shield 14. 16 Chimney or flue opening to the Cylinder 5
through the shield 14 for carrying off the aforesaid gases and moisture. 17 fan
and connections for blowing air into the Cylinder 5 to assist the drying of the Sugar
or substance being treated. A tapper or hammer may be used to strike the outer
Cylinder and cause sufficient vibration to prevent any material from adhering thereto.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is
First. Constructing drying and granulating apparatus with corrugated fluted or
grooved cylinders or cones substantially as set forth.
Second. Constructing drying and granulating apparatus with cylinders or cones
provided with discs or plates substantially as set forth.
Third. Constructing drying and granulating apparatus with hollow gudgeons
secured to the internal and external cylinders or cones substantially as set forth.
Fourth. Fitting the internal cylinder of drying and granulating apparatus with
a dip pipe secured to one of the hollow gudgeons substantially in the manner and for
the purpose set forth.
Fifth. Providing drying and granulating apparatus with a deflector and shield
substantially as set forth.
Sixth. Constructing the gudgeons of drying and granulating apparatus with
stuffing boxes and inlet and outlet pipes and driving gear substantially as set forth.
Seventh. Drying and granulating apparatus substantially as herein set forth.
