7 The present invention relates to improvements in dryingor carbomzmgapparatus of the type in which anumber of trays for supporting the material to be dried or carbonized are hinged at one edge, and are mounted to be rotatable about a central supporting axis,

being normally held horizontally by support ing rails which are interrupted at one point to allow the trays to swing down and Oilscharge their contents.

According to this invention a'central driv- 7 ing shaft is adapted to support a skeleton cellularframework, the floor of each individual cell being in the form of a tray pivoted on one radial'edge. 1

TheIinvention is more particularly described with reference to the drawings in which:

The carbonizing ordrying apparatus consists of a cylindrical chamber 1 provided at its top with an opening having a distributor'2 for feeding material, such as' pulverulent material to bercarbonized, to tiers of r y 7 3% afa i a aja y p a a a a p ported by a central shaft 15', and from the lower tier 3? of which the material is disrigid radial partitions accompanying with perforations their under surfaces adaptedto co-operate with a hired circular supporting rails 8, so

The lowerend of the casing-1 is closed by means of a conical end 5 provided with a conduit 4: connected to asource of hot gas, super heated steam or the like drying or carbonizing agent, which passes up through the material on the tiersof trays a, Z), 0 0, p, and escapes at an opening arranged inthe top 6 at the top of the c-hamber'l. Each tier of trays, a, b, c frame-work havin-gannul-ar rigid partitions 13,19, and 1. 18. To the edges of certain of these radial partitions are hinged pertorate'trays 2O (Fig.1?) by means of hingepins 21 These trays are provided 24 and have'rol'lers 23 on comprises a that'the trays are normally held horizontal for the support of the material upon them,

The leading edge of the gap in 8, i's preferably provided with a ramprail exten- .22 Of droppedposition smoothly again to the horizontal position sioni25,sot-hat the trailing edge has shown in Figure 9., a Material therefore, falling within the compartments or-cells of the frame work 14:

The material-will then be carried round on its tier also almost a complete revolution. until another gap in the supporting rail for r the trays of tier 6 occurs when the ma} terial willthen be discharged on to the tier 0." These discharge areas will be displaced by angularly from one say substantially 340 another, as for instance, shown diagram-Q matically in Figure 6 Where 9*, 9 9, 9 indicate the discharge areas of successive tiers. 1
