Description of the invention: • Technical field to which the invention pertains The present invention relates to a device for processing a particulate material, a chamber for containing and processing the particulate material, and having a bottom portion of the two guide plates, the overlapping guide plates are two on the top and forming an annular groove between the two guide plates, through which the substantially horizontal component movement with radial outward direction can be introduced Handle the air. [Prior Art] Such a device has been disclosed, for example, by DE 102 48 116 B3. This known device is used to dry, granulate or coat the particulate material. The gaseous medium "treatment air" is introduced into the processing chamber from the bottom and enters the processing chamber in a substantially parallel manner through a plurality of slots between the overlapping guide plates. / Due to the overlap of the annular guide plates, a plurality of grooves are formed therebetween, and a flow of process air flowing radially from the inside to the outside is formed in the process chamber, and the air flow is deflected upward by the wall to which the treatment is applied. The material to be treated is transported during the process, but settles down at the center due to gravity and again hits the air cushion of the process air. If a certain large range of points I is applied to the process air, a spirally rotating swirling flow ring is gradually formed. If a large agglomerate is to be formed from a fine dusty powder, i.e., if the material is to be granulated, it is necessary to spray a viscous dielectric through the nozzle to the spiral ring. In the initially mentioned DE 102 48 116 B3, for example, a spray nozzle pointing obliquely upwards is embedded in the wall of the container enclosing the processing chamber. During the coating, the coating layer is applied as uniformly as possible to the existing 1302851 larger body. That is, the coating layer is to be sprayed.

For this purpose, it is known to eject liquid from a slotted nozzle, e.g. under high pressure, and to eject it by means of a jet air orifice which occurs on one side or on both sides of the liquid gap. A spray nozzle having a flow path having a circular cross section is also disclosed in X DE 102 32 863 A1. Depending on the angle of the spray and the angle of the wrap, a sprayed thin layer of a radial, conical or varying extent is produced. The spray angle is 1 different. The angle of the corner is 36G. In the case of the production of a substantially planar jet, which is widely used in the pharmaceutical field (4) technical towel, efforts to achieve the result are as uniform as possible 'that is, 'to achieve a very narrow particle size distribution of the particles, and in (4) The coating layer is as uniform as possible on the coated flakes contained in the device, that is, the lang has the same thick, paint layer. A considerable problem is that the material listeners that are drifting in an uncontrolled manner and that are wet and often secretive (4) wet together adhere to form unwanted masses.曰 = This, in the spiral service material belt, it is desirable to precisely define the flow conditions that allow the processing results to be obtained. In particular, it is desirable that after the injection, the particles in the envisaged flight path may be separated from each other and will not move toward each other to prevent the formation of undesired agglomerates. SUMMARY OF THE INVENTION ^02851 Thus the object of the present invention is to read for improvement so that it can be achieved and two:: the order of handling of the particulate material. The outward enthalpy of a coordinated surface with a good processing result and the bottom of the stream that causes the center of the air to flow from the inside can be surprisingly leading to particularly coordinated and particulate materials. Discharge through the annular groove = pad's pad on the bottom from the (four) outer radial radial, and guide the granular material to be radially outward into the gradually increasing available space; The materials are first separated from each other. The particulate material carried by the process air flowing upward on the wall, the treatment air is vertically upward. These particles of material separated from the outflowing process air are moved toward the center in a radial direction toward the center, and gravity acts on the fortune, reading down the gas of the process air passing down the bottom. Since the annular gap nozzle is read in the middle and it has a thin layer of a plane formed from the nozzle, the falling material can be evenly colored and then immediately moved radially outward in a lightly directed manner, That is, the particulate materials can be removed from each other. Thus, the particulate material is sprayed in a very specific manner by spraying a thin layer as it is being dropped, and is padded by the process air cushion and moved radially outward. The granule material, after splitting the sprayed thin layer, is operable to point to a horizontally radially outward 1302851 $-step path whose subsequent movement is a vertical upward movement and a return to the center again for the purpose of The particulate material dries the sprayed particles by treatment air and solidifies them accordingly before hitting the sprayed layer again. Since the sprayed lamina has a complex wrap angle, all of the particulate material falling at the center can be uniformly sprayed by the sprayed liquid. It has now surprisingly been found that this combination enables optimum treatment of the uniformity of the granular material. The annulus nozzles act in a position similar to the "amidshiPs" and "underbed". The particulate material that descends onto the sprayed layer is lapped by the process air and is specially coordinated. It is handled in a uniform manner. ... Even in the case of very large test batches weighing up to 650 kg, the ideal granulation, coating and drying process can be achieved. The air cushion on the bottom side completely excludes the underside of the part. The blasting substance, that is, all of the blasting substance is added to the granule material, so that no blast loss occurs, which is particularly important in the pharmaceutical field. • In still another embodiment of the invention, air is supported. a discharge opening is provided between the orifice of the annular gap nozzle and the bottom portion below to form a support pad on the underside of the sprayed thin layer. It is generally known to create a certain amount of work in the region immediately adjacent to the spout, and The vacuum causes the particulate material to accumulate near the injection port. In the case of the spray thin layer mentioned at the outset, it is natural that the particulate material is lowered at the center and guided horizontally. On the upper side, there is no problem, however, on the lower side of the sprayed layer, this vacuum zone gradually causes the accumulation of particulate material. The support air is provided by an additional row of 1302851 vents to provide an 'annular gap nozzle. This area on the underside of the orifice area is not blown by the abutment air. An additional effect is that the supporting air can actually be supported on the underside of the jetted planar spray layer, ie The abutment air prevents undesired downward movement of the sprayed lamina due to gravity or a spray cone formed in the cross section. This eliminates jet loss or loss of viscous particulate material applied to the upper side of the bottom. Possibility. In a further embodiment of the invention, the support air is supplied from the annulus nozzle itself and/or by process air. These measures enable the introduction of support air in a number of different ways. The discharge enthalpy can be provided on the ring nozzle itself. , (d) the air is discharged through the = discharge port to help form the support air. In addition or alternatively, some of the process air flowing through the bottom can be guided by the spray _ The lower side of the layer can thus help to form the support air. In a further embodiment of the invention, the annulus nozzle has an approximate conical head' aperture disposed along the circular face of the conical section.

At the orifice and at the bottom located below, the frustoconical wall has the advantage of supporting such a measure by the above-mentioned coordinated deflection movement by the extension of the frustum and (iv) through the area The 1302851 supports the air and the supporting air provides support on the underside of the thin layer of the nozzle. In still another embodiment of the invention, an annular groove for passing air is formed between the undersides of the frustoconical wall. The advantage of this measure is that the air enthalpy of the transfer of the particulate material to the bottom can be controlled particularly effectively, and if initiated in a specific manner, this transfer can be done directly in the area below the nozzle.

Coordinated flow from the combination of the selected annular gap and the annulus nozzle has been shown to be very effective in adding additional material. Therefore, it is possible to directly apply the powder from the center, for example, when the sprayed thin layer is formed, so that the powder can be added to the surface of the object to be treated in a strong (four) manner, the surface becoming dry by the nozzle. As a result, during the coating, you can ride the thick money that you are currently wearing. advantage. Another - quite large advantage is that, this substance is allergic to humidity, so it cannot be seen from the point of view that only the jet of the sulphate side active material gap nozzle is sprayed, and the additional ice is added from the center of the private end. . From the off-shooting parameter, since the upper-to-knot== is the amount of flow considered, it is possible to complete the feeding to the two-degree eclipse coordination in another embodiment of the present invention, between the plates, these The flow component of the guide element at the point where it passes: air = 1302851. - This, the known measure itself has the advantage that it is possible to move the component of the corresponding domain by the % of the guides, so as to form a uniform spiral vortex of the vortex-type granular material, which results in uniformity. The ground strikes a thin layer of spray. • In the case of no county control, the features mentioned above and the features to be explained below can be used not only for specific combinations, but also for other combinations or for themselves. [Embodiment] The apparatus for processing particulate material as shown in the first figure is generally represented by reference numeral 10. Device 10 includes a container 12 having an upstanding cylindrical wall surface 14. This wall 14 encloses a corresponding processing chamber 16. The processing chamber 16 has a bottom 18 and the flow lion is located below the bottom 18. • As disclosed, for example, by 肫102 48 116 B3, which was originally mentioned, the bottom 18 consists of a total of 10 annular guide plates placed one above the other. The service guide plates are placed one on top of the other such that the outermost annular guide plates connected to the wall 14 are the lowest, and then the other nine inner annular guide plates are placed on the guide plates. The block annular guide plates partially overlap the respective annular guide plates. For the sake of clarity, only a few guide plates are provided with reference numerals, for example two guide plates 22 and 23 arranged in such a way that one block is placed on top of the other. By placing one piece on top of the other and leaving 11 1302851 between the two guide plates 22, 23" in all cases, a ring #槽25' is formed between the two guide plates Μ, Μ through the ring The trough 25, the process air 28 having a substantially horizontal component motion, can pass through the bottom portion 18, which of course is known to be embedded from below in the center of the uppermost inner guide (4). The annular gap nozzle 3 has an orifice 32 having a total of three orifice gaps 33, 34 and 35. All three of the orifice gaps, the material and the 35 are oriented such that they are jetted substantially parallel to the bottom 18, i.e., η has approximately 36 turns horizontally. Surround angle. The jet air is ejected through the upper gap 33 and the lowermost gap 35, and the liquid to be ejected is ejected through the intermediate gap %. The annulus nozzle 30 has a rod-shaped body 36 that extends downwardly and includes corresponding passages and feed lines, as is known per se. The rim nozzle 30 can be designed, for example, like an atomizing nozzle from DE 102 32 863 A1. Such an annulus 30 can be formed to have, for example, a "rotating annular gap" in which the wall faces of the passages through which the liquid is ejected are rotated relative to each other to exclude slagging or agglomeration so that the ejection from the gap 34 can be performed throughout 360 Uniform on the surround angle. Therefore, the injection angle is 180 with respect to the longitudinal axis of the main body 36 of the annular gap nozzle. . The annulus nozzle 30 has a conical head 38 above the aperture 32. In the region below the orifice 32, there is a frustoconical wall 40 having a plurality of openings 42. It can be seen from Figure 1 that the lower side of the frustoconical wall 4 turns over the innermost guide plate 24, in such a way that on the underside of the frustoconical wall 4〇 and below and partially Between the guide plates 24 on which the wall faces 4 are overlapped, a groove 26 through which air can be processed is formed. 12 1302851 The flow conditions formed during the test operating state are shown in the right half of Figure 1. A planar spray thin layer 44 exits the orifice 32. While the opening 42 in the frustoconical wall 40 can be air or a hollow lion, the support air 46 is formed on the underside of the sprayed layer 44. Since the process air 28' passing through the plurality of slots 25, forms a radial flow in the direction of the wall surface 14 and deflects upwardly through the wall 14, as indicated by arrow 48. The process air 28 and the particulate material to be treated are now separated from one another, the process air 28 is discharged through the outlet, the vortex particulate material radially ramps up, and settles vertically downward in the direction of the conical head 38 of the annulus nozzle 30 due to gravity. . The descending material is smoothly transferred to the position and introduced onto the upper side of the sprayed layer 44 where it is treated by the sprayed particulate material. The jetted particulate material in the sprayed lamina 44 is separated from each other' of course because the space available for the particulate material after exiting the annular orifice 32 becomes quite large. In the region of the sprayed thin layer 44, the particulate material to be treated collides with the liquid particles and remains in this direction of movement, separated from one another, and the particulate material is treated uniformly and harmoniously in the process. Treatment, that is, they are dried. Portions similar to those in the first figure are shown in a perspective view in a second view, and the apparatus shown in the second figure is generally represented by a reference numeral 5〇. There is also a container 52 having an upright cylindrical wall %, which defines a processing chamber 56. As described above in connection with the description of the figure, the bottom portion 58 is composed of guide plates 62, 63 which are respectively placed on top of each other, for example, only two guide plates 62 and 63 are designated here. The inflow chamber 6 is then also located below the bottom 58. 13 1302851 It is shown here that the guiding elements 64 and 65 are arranged between the guide plates 62, 63 which result in the condition that not only the process air 68 passing between the guide plates 62 and 63 is exactly radial It flows outwardly and exerts a certain range of component motion on the process air 68 as indicated by the arrows. Also at this point, the corresponding annular gap nozzles 7 as described above are also arranged at the center. For example, a feed member 72 such as a pipe fed from the side is at the center

Orifice? The position of 4 can be adjusted vertically. This makes it possible, for example, to place the solid in the form of a powder 78 from the upper side of the spray thin layer of the plane ejected from the annular gap nozzle 70.
