- the outer diameter of the additional twist blading corresponds to the outer diameter of the dust separator 12.
- the swirl blading generates and promotes a pre-swirl or swirl flow over a fluidized bed present in the process space 20, thereby assisting the required and desired on-going transport from the feed cell to the discharge cell, not only for fine particles.
- a centrifugal field is generated, in which the dust particles and entrained particulate materials are externally circulated and discharged through an opening.

- Preferred embodiments of the invention are also characterized in that at least two closure members are provided, wherein preferably the closure members are evenly distributed on a concentric circle around the shaft around.
- each closure member is movable from bottom to top along the third opening, preferably on a circular arc.
- each closure member in the n-th cell and the associated drive device are arranged outside of the container, so that the shaft between the drive device and the closure member passes through the outer contour of the container.

- the fourth opening is at least partially closed at least temporarily, preferably by a further closure member of the discharge.
- Preferred embodiments are further characterized by a wall between the nth cell and the first cell, this wall having no opening.
- n cells are arranged concentrically around the treatment device, preferably comprising a superheater.

- the invention also provides a method for removing at least fluids from a batch of particulate materials in a device according to the invention, characterized in that the residence time of the particulate material in the process space of the device is determined as a function of a fluidized bed differential pressure in the process space.
- each of the third opening closing closure member is first rotated from its respective closed position into a third opening, preferably completely releasing opening position, preferably at the third opening from bottom to top sweeping past, and then the closure member is held in the open position for a first certain period of time.

- At least one closure member initially closes the third opening either from top to bottom or from bottom to top.
- the invention also proposes that the process space is filled with a mixture of particulate materials in such a way and a fluidizing agent is supplied to the process space such that at least in the (n-1) -th cell the fluidized bed builds up at least up to the fourth opening.
- the invention is thus based on the surprising finding that during operation of the drying device with a continuous feed of particulate matter to be dried and a continuous discharge of dried materials, a fluidized differential pressure gradient is formed, which on the one hand is sufficient as a driving force for transport the fluidized particulate material to be dried from processing cell to processing cell and secondly provides for continuous particle movement in front of a closure member which is necessary only between the last processing cell in which the fluidized bed is spreading and the fluidized bed discharge cell when the closure member is not used for closing an opening of a wall between said last fluidized bed processing cell and the fluidized bed discharge cell, but for closing an opening of a space between besa Gter last processing cell and the discharge cell, so that it does not lead to jamming of particles and / or an accumulation of heavy fluidizable product in front of the closure member.
- the knowledge is used that, when the amount of supplied particulate materials of the fluidized bed is increased, the fluidized bed differential pressure increases, so that to ensure steady-state process conditions in the fluidized bed with approximately constant filling and product residence time adjustment of the discharge the at least partially at least fluid-free particulate materials have to be made in dependence on said fluidized bed differential pressure.
- This allows for a controlled amount of particulate materials in the fluidized bed, while optimizing the removal of the fluids from the particulate material. Further, even with momentary interruption or reduction of the supply of said mixture of particulate materials into the process space, it is ensured that the fluidized bed in the process space does not become depleted and thus maintained on fluidized materials.

- Figure 4 is a perspective view of a locking device of the device of Figures 1 to 3;
- FIGS. 5a to 5c show partial sectional views through a processing cell and a delivery cell of the device of FIGS. 1 to 3, with different positions of the closure device of FIG. 4;
- Figure 6 is a partial perspective sectional view of a known device.
- FIG. 7 shows a sectional view along line DD of FIG. 6.
- a drying device represents a further development of the device 1 described with reference to FIGS. 6 and 7, wherein identical parts are identified by the same reference symbols and will not be described again below. More specifically, the drying device 1 according to the invention, as shown in different perspective partial sectional views in FIGS. 1 to 3, differs from the known drying device 1 of FIGS. 6 and 7 essentially by a closing device 40, which is shown in detail in FIG is.
- the locking device 40 comprises according to Figure 4, a shaft 41 for connecting two closure members 42a, 42b with a drive device 43.
- the closure members 42a, 42b are arranged in cross-section on a circle which is concentric with the shaft 41, and uniformly along the circle distributed so that they are, so to speak, opposite.
- the drive device 43 of the closing device 40 is arranged outside the outer skin 3 of the drying device 1, while the closure members 42a, 42b are rotatably arranged in the discharge cell 17 via the shaft 41.
- the dispensing cell 17, which has no distributor plate, is not arranged directly adjacent to the last processing cell 16 with distributor plate (not shown) in the area of the closure members 42a, 42b, as can be seen, for example, in FIG Incoming floor reference is made to the figure 5a - 5c.
- FIGS. 1 to 3 that between the processing cell 16 and the discharge cell 17 there is arranged a gap, which is referred to as a loosening space 19 for reasons explained in more detail later.
- a boundary wall 19b is mounted on the wall 8a between said processing cell 16 and the discharge cell 17 in the region of the opening 8b, which is a recess of the wall 8a at the end facing the inflow bottom, so that the loosening space 19 via the opening 8b with said Processing cell 16 and via a further opening 19 a to the discharge cell 17 is connected.
- the loosening space 19 is bounded above and laterally by the boundary wall 19b and down through the distributor plate, see in particular the figures 5a to 5c.
- the opening 19a of the loosening space 19 can be closed via one of the closure members 42a, 42b, as shown for example in FIG.
- a fluidizing agent for example in the form of heated in the superheater 6 and the fan wheel in the bottom 5 through openings in the distributor plate 7 of down to the top blown steam, introduced into the process chamber 20, so a fluidized bed in the process chamber 20 is built up, and with it a fluidized bed differential pressure.
- This fluidized bed differential pressure is proportional to the amount of particulate materials in the fluidized bed.
- the driving force for the transport of material from the entry cell 15 to the discharge cell 17 consists in a permanent fluidized bed differential pressure difference, which adjusts in a continuous operation of the drying device 1 from the entry to the discharge out.
- the transport of material in this case runs from the entry cell 15 via the processing cells 16 in the discharge cell 17, through openings in the partitions 8, such as the opening 8b in the partition wall 8a between the last processing cell 16 with distributor plate 7 and the discharge cell 17 without distributor plate.
- materials must be able to flow out of the fluidized bed in accordance with the inflow of the materials, that is, leave the drying apparatus 1 through the opening 17a. This can be done in different ways.
- loosening of the particulate materials actually takes place in the loosening space 19, which prevents particularly coarse product particles from forming during a longer closing phase, for example by agglomeration, which can then no longer be discharged from the process space 20, but rather to a blockage in the loosening space 9 would lead.
- three variants of the discharge of material from the process space via the opening 17a are described:
- the closure member 42a is rotated from the closed position shown in Figure 5a to the opening position shown in Figure 5b, in a clockwise direction. This direction of rotation is important because it ensures that the closure member 42a sweeps past the opening 19a from bottom to top, so that coarser parts do not lead to jamming between the closure member 42a on the one hand and the wall 8a and / or the outlet bottom 7 on the other hand.
- the closure member 42b is then returned to its closed position and remains there for a fixed period of time.
- the speed of the rotary movement must be so great that the fluidized bed in front of the discharge cell 17 is not depleted of solid by a too long opening time of the loosening space 19. A speed of 10 to 20 revolutions per minute is desirable.
- a plurality of closure members may be appropriate to influence the opening times. If the flow of product from the processing cell 16 into the discharge cell 17 becomes too great, one of the closure members 42a, 42b may also be rotated to a partially open position, see, for example, Figure 5c, and remain in that position.
- the duration of the closed as well as the open state of the loosening space 19 is to be regulated as a function of a fluidized bed differential pressure. This is measured by two pressure sensors 44a, 44b, wherein the one pressure sensor 44a above the fluidized bed and the other pressure sensor 44b, as already Figures 1-3 removable, within the fluidized bed in close proximity above the Ausströmboden 7 of the processing cell 16 is arranged.
- the individual positions of the closure members 42a and 42b are targeted by the drive means 43, which may comprise a geared motor with positioner.
- the conveyor 30 may be used.
- the closure member 42a may, as shown in Figure 5c, be in a partially open position in which the lower edge of the closure member 42a is above the lower edge of the opening 19a of the loosening space 19. Due to the opening of the loosening space 19 thus given, particulate materials can pass from the processing cell 16 into the discharge cell 17 after passing through the loosening space 19, the quantity of which can be regulated as a function of a detected fluidized bed differential pressure by changing the position of the closure member 42a.
- the closure member 42a can fully open the opening 19a for a short period of time at a predetermined time, as shown in FIG. 5b, namely to allow discharge of any coarse particles present.
- a complete opening of the opening 19a thus finds a kind of "cleaning" of the loosening space 19 and thus also in the existing in front of the closure member 42a in its partial closed position fluidized bed.
- the required rotational movement of the closure members 42a, 42b also depends on the number of closure members.
- the opening 8c acts as a stationary weir, which allows particulate materials to enter the discharge cell 17 from the processing cell 16.
- Wall 19b delimiting wall wall 20 process space b opening 30 conveyor c opening 40 closing device
