' OF SURESNES, FRANCE.
DRYING APPABATUS.
No. &85,360.
To all 'whom 'it may concern:
Be it known that I, LON MoUnGEoN, a citizen of the Republic of France, residing in Suresnes, France, have invented certain new and useful Improvements in Drying Apparatus, of which the following is `a specification.
Drying of moist materials is avery frequent operation in most industres, and it is necessary, from the oint of view of economy, to be able to obtan complete and quick drying so as to avoid the accumulation of the material for a very long time, which occupies a considerable amount of space.
This invention relates to an apparatus for quick drying, enabling any moist materials to be dried, provided that they are neither in very large pieces nor in the form of a very fine powder. This apparatus enables the process to be carried out in practice in a very simple manner, the said process consisting in causing the material whch is to be dried to move in one direction in very thin layers at the same time subjecting it to the action of a hot fluid circulating in the opposite direction.
The apparatus according to this nvention is illustrated, by way of example, in the accompanying drawing Fgure l is a vertical section showing the complete apparatus. Fig. 2 is a horizontal cross-section on line A-A of Fig. 1. Figs. 3 and 4 are lans of disks mounted on the central spin e of the apparat'us. Fig. 5 is a detal vertical section of a modified form of the apparatus, and Figs. 6, 7 and 8 are sections on lines 6, 6, 7 7, 8, 8 respectively of Fig 5.
The apparatus chiefiy comprises a cylindrical tower a divided into chambers 1, 2, 3, 4 etc., by perforated fixed horizontal partitions b. The perforations in the said partitions are such that, while admitting hot air passing through the apparatus in the upward direction, they prevent direct passage from one chamber into the other of the material to be dried. Each horizontal partition has an opening in the center, and the edge of the said o ening is Secured to a cylinder c opened at bot ends.
Each cylinder c, as shown in Fig. 2, is dicompartments by radial partitions d d (1 d These radial artitions are connected to a central soe et e throu h which passes the vertical spindle f exten ing throughout the whole height of the The vertical spindle receives a apparatus.

rotary movement by means of any suitable ear.
On the said s indle are mounted:-
1. Perforate clisks g of a diameter smaller than that of the tower, provided underneath with scrapers h, which being driven by the spindle, move above the fixed partitions b; the said scrapers are arranged so as to push from the circumference towards the center the material Situated on the partitions b.
2. Disks 7; and i' with a sector cut out. The disks i and i each of which is provided with an openingj or j' are mounted one on each end of the cylinders c. The disksi and i' are keyed to the spindle f in such manner that the openings are at an angle of 180 relatively to each other. It follows therefrom that, if one cylinder c is considered, one of its compartments could never be opened at the same time at both its ends. In fact, if the open sector j of the upper disk i coinc'ides with the upper opening of'one of the compartments of the cylinder c, the sector j arranged at 180 relatively to the sectorj,w1lln'ot coincide with the bottom opening of the same Compartment, and vice-versa.
Above each of the disks g are Suspended from arms secured to the cylinder c and wall of the tower, fixed scrapers 0 arranged in such manner that the material falling on the disks g should be forced to travel from the center towards the circumference. At the bottom portion of the vertical tower is arranged an automatic extractor of dried material, for instance a screw conveyer. The moist material is introduced into the apparatus through the upper opening k. Hot air enters through the bottom opening l and escapes through the upper opening m.
The working of the apparatus is as follows 2- The hot air passes through the apparatus in the upward direction and the vertical spindle f rotates in a uniform manner at a s eed depending on the nature of the material to be treated. The material to be dried is introduced into the ap aratus throu h the opening k, falls on the ETS) horizonta partition b, the perforations of which are too small to allow the material to fall direct on the partimovable disk i, it fills successively the compartments of the cylinder c. The said conipartments are emptied also oWing to the sector j of the movable disk 73 arran ed at the bottom of the oylinder, but as aready stated above, a compartment cannot be emptied except When it is closed at the top by a solid portion of the disk i. The material escapng fron one of the con artments of the cylnder c falls on the mova le disk g, and the fixed scrapers 0 return the material towards the circunference of the disk Whence it falls on the second horizontal partition b Where it is subjected to the acton of the sera ers h as on the first horizontal partition, Whic brings it toward the center into the compartments of the second cylinder. The material thus travels in the downward direction in the a paratus, spreading in a thin layer on each liorizontal partition Where the rising hot air passes through it, While on the contrary the said material passes in a compaet mass 'from one parttion to another through the compartments of the difierent cylinders which are not accessible to the hot air. At
the bottom of the apparatus the dried Ina- *fixed partitions b 'and Would fill the central opening and the disks i Would be mounted on the arge bases of the truncated cones.
Having thus described my nvention, I claim:
1. In a drying apparatus, the combination of a partition having an opening, an openended cylinder fixed in said opening, a shaft passing through said cylinder, and disks on said shaft at opposite ends of said cylinder to control the passage of material through the latteri 2. ln a drying apparatus, the conbination of a fixed horizontal partition having an opening, a sha'ft passing through said opening, an open-ended cylinder fixed in said opening and divided into compartments, and means niounted on said shaft at opposite ends of the cylinder to control the passage of the material through said compartinents.
3. In a drying apparatus, the combination of a partition having an oening, an o enended cylinder fixed in said opening an dvided into a plurality of vertically extending con p artrnents, a rotary shaft passing through said cylinder, and disks on said shaft at the ends of said cylinder and having cut-outportions so arranged that When each compartment is open at one end it is closed at the opposite endi 4. In a drying apparatus, the combination of a horizontal partition having an opening, an open-ended cylinder having its upper edge fixed to the edge of said opening, partitions which divide said cylinder radially into a plurality of vertically disposed Compartments, an upright shaft passing centrally throu h said cylinder, and disks mounted on said s aft and extending over the ends of said cylinder, said disks having sector-shaped cut-away portions out of vertical alinement With each other.
In testiinony Whereof I have signed this specification in the presence of two subscribing witnesses.
