To all whom it may concern:
Be it known that I, PEDRO MARIA VELILLA, a citizen of Colombia, residing at Medellin, in the county of Medellin and Republic of Colombia, have invented certain new and useful Improvements in Drying Apparatus; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.
The present invention relates, generally, to improvements in drying apparatus; and, the present invention has reference more particularly to a novel construction of drying apparatus for drying any kind of granular material such as coffee beans, grain or similar material.
The present invention has for its principal object to provide a novel construction of drying apparatus, for the purposes above mentioned, in which a current of hot-air is caused to be circulated through the material operated upon by the said apparatus so that the moisture of said material may be carried olf or evaporated thereby.
A further object of the present invention is to provide means in connection with said novel construction of drying apparatus whereby the material to be dried is constantly shifted and kept in movement to permit the hot air circulating through said apparatus to come in contact with all parts of the mass of said material to be dried, and thereby further aiding in the proper circulation and passage of the hot-air through said apparatus.
A still further object of the present invenmtion is to provide a means for generating and conducting the current of hot-air into and through said drying apparatus.
Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of this invention.
With the various objects of my present invention in view, the same consists, primarily, in the novel drying apparatus hereinafter set forth and, the invention consists, furthermore, in the novel arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more Specification of Letters Patent.

fully described, and then nally embodied in the clauses of the claim, which are appended to and which form an essential part of the specification.
The invention is clearly illustrated in the accompanying drawings, in which:
Figure 1 is a front elevation of the novel construction of drying apparatus embodying the principles of my present invention, the hot-air generating furnace being illustrated in vertical cross-section to more clearly illustrate the bank of hot-air pi es contained therein. Fig. 2 is a detai central vertical section of said drying apparatus illustrating more particularly the interior construction of the same. Fig. 3 is a horizontal cross-section of said drying apparatus taken on line 3-3 in said Fig. 1, and

Secured upon said air-pipe 48, preferably between the arch-member 46 and said bearingplate 44, is a driving-pulley 50 by means of which said air-pipe 48 may be rotated. Secured upon the outer circumference or surface of said air-pipe 48, and extending upwardly from the bottom-plate 34 to a point below the top of said cylindrical shell 28,
is aconveyer-member 51 arranged in the K manner of an ascending spiral and adapted to revolve with said air-pipe 48. Arranged around said conveyer-member 51 is a cylindrical-wall 52 provided with a plurality of perforations 53. Said cylindrical-wall 52 is supported in its operative position by means of supporting-braces 54 which are secured thereto in any suitable manner, and the opposite ends of which are secured, in any suitable manner, to said cylindricalshell 28. Secured to the lower end of said cylindrical-wall 52 is an outwardly flaring conical plate or apron 55, the free edge of which terminates within a short distance from the inner surface of said bottom-shell 33 so as to provide a space 56 through which the material to be dried is permitted to pass to the space 57 where it can be taken up by the conveyer-member 51. This plate or apron 55 assures a perfect mixture of the material to be dried so that it may be uniformly heated and dried, and the said plate or apron 55 furthermore prevents the said material to be dried from becoming jammed or improperly fed to said conveyer member 51.
Having thus described the general 'construction of my novel drying` apparatus together with the various parts which go to make up the same, it remains to describe the operation of the same in carrying out the process of drying the material placed therein.
Assuming, for the sake of example, that it is desired to dry a quantity of coffee. In such a case the desired quantity of coffee beans are placed within the cylindrical shell 28 so that it fills the space between said cylindrical shell 28 and the cylindrical-Wall 52. The air-pipe 48, together with the conveyer-member 51 connected therewith, isf" then revolved by means of the driving pulley 50. The operation of said blower-fan 19 is then started. The said blower-fan 19 sucks air through the said air-pipes or ducts 12, which being surrounded by the burning gases and heat generated in the fire-box of said furnace 6 causes the air thus passing through the air-pipes or ducts 12 to be heated and passed into the collector-chamber 15. This heated air is then drawn from said collector-chamber 15 and forced by said blower-fan through the air-conduit 26 and down into the revolving air-pipe 48. In the meantime the coffee-beans flow downward by force of gravity through the opening or space 56 to the foot of said conveyer-member 5l. The said conveyer-member 51 carries the codec-beans upwardly within the cylindrical-wall 52 until the top thereof is reached, whereupon the said coffee-beans fall over the edge of the same and back into the cylindrical-shell 28. In this manner the coffee-beans are kept moving or circulating through the drying apparatus, and are thoroughly mixed so that all parts of the mass are brought in contact with the airpipe 48. The hot-air Within said air-pipe 48 finds its way through the perforations 49 and thence permeates the mass of coffeebeans carried by said conveyer-member 5l. The said hot-air then passes through the perforations 53 of the cylindrical wall 52 and finding its way through the mass of coffee-beans within said cylindrical-shell 28 nally escapes through the perforations 31 of said cylindricabshell 28. In this manner the moisture of the coffee-beans is taken up by the said hot-air and carried on or evaporated. Of course it will be readily understood, that if it is so desired, the upper portion or opening of said cylindrical-shell 28 may be provided with a closure such as doors or covers or the like.
I am fully aware that changes may be made in the arrangements and combinations of the various parts as well as in the details of the construction of the same without departing from the scope of my present invention as set forth in the appended claims. Hence, I do not limit my invention to the eX- act arrangements and combinations of the devices and parts as described in the foregoing specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
