Claims. (C1. 34-12) This invention relates to driers and in parspaced guide rails 8, supported by the vertical ticular to a continuous drier wherein the mateframe members 2 and by additional superstrucrial to be dried is carried on an endless supture as indicated in Figure 1. The material to port and during the course of the drying operabe dried is fed in a wet condition to the endless 5 tion is turned over by means of a rabbling device. conveyor 5 by means of a hopper 9, supported 5 In general the object of my invention is the above the endless conveyor by means of suitable provision of a drying chamber through which a superstructure. Secured to the superstructure at bed of discrete particles to be dried is passed, the opposite end of the drier is a hopper H into and which is provided with a plurality of spaced which the dried material is discharged. Mounted discs which serve to turn over the particles formintermediate the ends of the upper compartment 10 ing the bed, and thereby present new surfaces of the heating chamber l and between the lateral to the drying medium. walls l2 of the chamber, is a shaft l3. This More specifically the object of the invention shaft may be conveniently journaled in bearings is the provision of a rabbling device comprising ll carried by the lateral walls l2, and is designed 1 two sets of discs mounted on a shaft, the memto be driven by means of a pulley l5 secured to bers of each t being parallel nddisp s d lnterone r its ends and which in turn may be driven mediate the members of the other set, the discs by means of a motor Ii carried by the superof one set being disposed at an angle with resp'e'ct structure of the device as shown in Figure 1. to the discs of the other set. Since the drier per se including the endless congo Th i v t n possesses Other dvantageous veyor and pallet construction is well known to features, some of which With the foregoing, will the industry the details of its construction need be set forth at length in the following de'script b i tion where that form of the invention which has As shown in Figure 3 t haft l3 h b been selected for illustration in the drawings provided with two Sets f spaced discs The discs accmnllanymg and fuming Part the Pres" ll constituting the members of one set are each 25 cut specification is outlined in full.

It is to be noted that the discs n 80 Referring to the drawings: fie intermediate the discs Figure 1 is a diagrammatic side elevation of In Figure 4 two Sets of discs have again been an endless drier embodying the (Meets of my shown.

' preferable to the arrangement shown in Figure As the result of actual tests madewith this type of equipment, it has been found that the arrangement of discs as shown in Figure 4 is 3, and that the emt shown in Figure 8 is preferable to th arrangement shown in Figure 5. Inthearra ement showninl'lgure! the particles forming the bed of material are turned over without crushing the individual particles and without forcing them into and injuring the. supporting screen. In the arrangement shown in Figure 3-there is inclined to be a slight crushing. of the particles and in the arrangement shown in Figure 5 this action is even more pronounced, although in both of the latter modificationsthere is no tendency to force the material into the supporting screen.
