    description
    Background Art The present invention relates to a granulation plant. The granulation plant is particularly modular and allows automated high-throughput granulation.
    Since in the production of granules currently mainly manual process steps are performed and these are costly and time-consuming, the automated high-throughput granulation described in this invention relates to the optimized and automated process flow of a granulation.
    [0003] The methods used so far in detail:
    High-shear granulation The already weighed and sieved powder for granulation is filled in a so-called high-speed mixer - which usually has a conical or cylindrical shape. This homogenizes the powder bed with a very high stirring frequency (horizontal movement in a circle and vertically). Subsequently, the granulation liquid is applied to the homogenized - still moving powder bed. The compaction of the granules takes place by the centrifugal forces and the weight of the overlying grains. Unlike the fluidized bed process, a build-up mechanism is first started, followed by a decomposition mechanism. This is done by compacting the moist granules, which are then crushed again by a high-speed chopper in the stirred tank. Then the still moist granules are sieved, then dried (i.d.R. in a fluidized bed system) and sieved again.
    Fluidized bed granulation After prior sieving and weighing of the powder, it is filled into a conically shaped product container. By a fan, an air flow (supply air) is generated, which puts the powder bed in a fluidized mass. The conical shape of the product container means that the air velocity at the bottom is maximum and decreases towards the top. This mixes the powder parts. Subsequently, a predefined amount of liquid (in cocurrent or countercurrent process) is sprayed onto the moving powder bed by means of a spray nozzle and the drying is initiated by changing the supply air temperature. Any particulate matter that may arise is captured by exhaust air filters and thus does not get into the outside air. By tapping the filter they are freed from adhering powder. The fluidized bed granulation can thus be divided into the phases preheating, granulation and drying. The product moisture changes significantly depending on the phase. After the granulation is finished, the granules are sieved again.
    Fluidized bed drying [0006] In the same principle of fluidized bed granulation, the previously granulated powder (for example in the high shear mixer) can be dried by means of a fluidized bed system with a corresponding supply air temperature. It only eliminates the addition of the binder.
    Coating process The coating of granules likewise usually takes place in the abovementioned fluidized bed.
    DISCLOSURE OF THE INVENTION The plant according to the invention is used in particular for automated high-throughput granulation. This plant is preferably designed for laboratory purposes and combines the manufacturing processes of wet granulation, in particular rapid mixed granulation and fluidized bed granulation in a plant. This results in automated high-she-gran granulation with a top-drive system including fluidized-bed drying and coating. Task of the machine is the production of various granules, advantageously in very small quantities. In contrast to the production of large quantities, the production of very small quantities in fully automated plants as well as high-throughput research is largely unexplored and is usually carried out manually. An additional unit can be used to produce both very small quantities and larger batches. Full automation leads to cost and time savings in the production of the granules.
    The plant for automated high-throughput granulation is developed inter alia to incorporate non-integrated process steps of the granulation in the process flow. This simplifies and speeds up process steps. The machine operates fully automatically, resulting in time and cost savings. In addition, the construction of a single machine saves space. Furthermore, new and different formulation developments and formulations can be produced. For this purpose, different powders in the granulation container are mixed and further processed by means of powder dosing. The granules produced can then be coated again, for example, or granulated with another powder.
    The inventive granulation plant comprises at least one housing element which extends between a bottom surface and a lid surface. The bottom surface and / or top surface preferably have openings through which materials or processing elements can be introduced into the housing element. Both a closure element and a stirring element comprising a housing closure can be attached to the bottom surface and to the lid surface, wherein in particular both elements can not be attached to the same surface at the same time. The closing element is used in particular for at least partially closing the opening on the bottom surface and / or lid surface. The stirring element also serves in particular to close such, but preferably also engages in the housing element in order to influence material arranged therein, in particular to stir and / or grind and / or comminute. The housing element also has in each case at least one holding device for the bottom surface and the top surface. About the holding device, the closing element or the stirring element on the housing element is firmly held. Particularly advantageously, the holding device for the bottom surface is independent of the holding device for the lid surface. Particularly advantageously, the holding devices for the bottom surface and the lid surface are formed identically. By holding devices, different elements can be attached to the housing element, whereby the granulation can be modular. In particular, therefore, a modular system is realized, which allows a simple and low-cost assembling a granulation from a variety of individual elements with desired functionality. Thus, the granulation advantageously for a laboratory operation.
    The dependent claims show preferred developments of the invention.
    Particularly advantageously, the closing element comprises a cover element for completely closing the bottom surface and / or lid surface. Thus, leakage of a content of the housing member is prevented. Likewise, no foreign body can enter the housing element. In particular, the housing element is completely sealed by the cover element. Alternatively or additionally, the closing element comprises a sieve element for sifting a content of the housing element. The screen preferably has an aperture of a predefined size so as to retain objects of greater dimension than the predefined size. Likewise alternatively or additionally, the closing element has a fluid-permeable element for introducing a fluid into the housing element. On the other hand, entry or exit of solids into or out of the housing element is prevented. Air can thus be injected particularly advantageously into the housing element, particularly advantageously in order to produce a fluidized bed. Finally, it is alternatively or preferably provided that the closing element has a filter element for collecting a content of the housing element. The filter element is particularly advantageous to use when also a fluid-permeable element is used as described above. This allows an introduction of fluid, in particular an injection of air, into the housing element, wherein the air can escape via the filter element, while the content of the housing element, in particular in powder, is retained by the filter. For this purpose, the fluid-permeable element is preferably attached to the bottom surface, while the filter element is attached to the lid surface or vice versa.
    Preferably, the housing element has a cylinder jacket-shaped outer wall. At the end faces of the cylindrical shape are the bottom surface and the lid surface. Such a design allows a simple composition of the individual components of the granulation.
    Advantageously, it is provided that the holding device comprises magnets with which the closing element and the stirring element are durable by magnetic force. Thus, a connection of the housing element and the end element and / or stirring element is made possible in a simple and low-effort manner. In particular, the granulation can be easily, quickly and with little effort disassemble and reassemble. Thus, a conversion can be easily made, so that the granulation plant is optimally suited for laboratory use. At the same time, it is ensured by the magnets that the closing element and / or stirring element are securely and reliably fastened to the housing element.
    The granulation preferably has a connecting element, via which two housing elements for fluid communication can be connected, the connecting element is used in particular for connecting the holding devices of two housing elements, wherein at the same time a junction of the housing elements is sealed against an environment. In addition, a termination element, in particular the screening element described above, may be attached to the connection point between the housing elements.
    In a preferred embodiment, the granulation system comprises a first housing element, a second housing element and a plurality of different termination elements and / or stirring elements. The housing elements and the end elements and / or stirring elements can preferably be composed variably to realize different functionalities. Furthermore, the granulation plant has a first station for performing a granulation step and / or a sieving step and a second station for performing a drying step. It is provided that the first station and the second station are formed by different combinations of the first housing element and / or the second housing element with the end elements and / or stirring elements. In particular, therefore, the first station and the second station are not present at the same time, but are formed from the housing elements, termination elements and stirring elements as needed. In particular, a product can thus always remain in one of the housing elements, while a different treatment of the product is made possible by the attachment of different end elements and / or stirring elements.
    Particularly advantageously, the first station is formed by providing the stirring element in the first housing element and / or the second housing element. The stirring element thus permits thorough mixing of substances within the first housing element and / or second housing element. In addition, the stirring element is advantageously used to support a screening process.
    Furthermore, it is particularly advantageously provided that in the first station, the first housing element for fluid communication with the second housing element is connected. In addition, a screen element between the first housing element and the second housing element is arranged. The stirring element is in particular mounted in the first housing element and thus serves to assist a screening process of a product which is located in the first housing element and which is to be screened into the second housing element.
    Advantageously, a fluid-permeable element and a filter element are also arranged on the first housing element and / or the second housing element in the second station. For this purpose, the first housing element and the second housing element are preferably connected via a connecting element. Advantageously, the fluid-permeable element is attached to the bottom surface of the second housing element, while the bottom surface of the first housing element is attached to the cover surface of the second housing element. On the cover surface of the first housing element, the filter element is mounted. Thus, a fluidized bed can be produced by blowing air into the first housing element and the second housing element through the fluid-permeable element, while the air can escape again via the filter element, but the contents of the first housing element and the second housing element are retained.
    Preferably, the granulation plant on a third station. The third station is for performing a granulation step and / or a coating step and / or a drying step. In particular, the first housing element and / or second housing element is formed at the third station as a fluidized bed system. In the third station, a fluid-permeable member and a filter element are disposed on the first housing member and / or the second housing member, wherein in the filter element, an injection nozzle for coating material is attached. Furthermore, the first housing element and the second housing element are preferably connected via a connecting element. In this way, said fluidized bed system is constructed. It is preferably provided that the bottom surface of the first housing element has the fluid-permeable element, while the cover surface of the second housing element has the filter element. Via the connecting element, the cover surface of the first housing element and the bottom surface of the second housing element are connected. Thus, a fluidized bed can be generated within the first housing element and the second housing element, wherein a coating material can be injected into the fluidized bed through the injection nozzle in the filter element. The filter element ensures that no product can escape from the first housing element and / or the second housing element. Only the injected to generate the fluidized bed via the fluid-permeable element air can escape through the filter element.

    EMBODIMENTS OF THE INVENTION FIG. 1 shows schematically a housing element 1 according to an embodiment of the invention. The housing element 1 is shaped like a hollow cylinder and has a bottom surface 2 and a cover surface 3. The bottom surface 2 and the top surface 3 are end surfaces of the case member 1. The case member 1 is provided on the end surfaces, i. opened at the bottom surface 2 and on the lid surface 3 and closed at the peripheral surface via an outer wall 11.
    By providing different elements on the bottom surface 2 and / or the top surface 3, different functions can be realized. In order to fasten the elements to the housing element 1, the housing elements 1 have a holding device 10. The holding device 10 comprises magnets in order to hold the elements on the housing element 1 by magnetic forces. Said element is in particular a cover element 4. This is shown in Fig. 2.
    FIG. 2 shows the housing element 1 from FIG. 1 in a sectional view, which has the cover element 4 on the bottom surface 2. For this purpose, the cover element 4 is fastened to one of the holding devices 10 of the housing element 1. In particular, the cover element 4 is ferromagnetic or comprehensive. Magnets to cooperate with the magnetic holder 10. Thus, a secure and reliable hold of the lid member 4 is ensured. The housing element 1 with the cover element 4 can thus be used as a cup.
    Fig. 3 shows a further view of the housing element 1, wherein two cover elements 4 are present. The cover elements 4 are thus attached to the bottom surface 2 and to the cover surface 3 of the housing element 1. For this purpose, each cover element 4 is connected to its own holding device 10 of the housing element 1, so that the cover elements 4 can be connected to the housing element 1 independently of one another and separated from the housing element 1. The inner volume of the housing element 1 is thus completely separated from the environment by the cover elements 4.
    An alternative element that can be attached to the bottom surface 2 or the lid surface 3 is a stirring element 8. This is shown in Figs. 4 and 5. 4 and 5 show different views of the housing element 1 with attached to the bottom surface 2 cover element 4 and inserted stirring element 8. The housing element 1 in such a configuration is particularly suitable for filling and mixing of different substances.
    The stirring element 8 has in particular to the shape of the outer wall 11 adapted wing elements 12. The wing elements 12 ensure that the entire cross-sectional area of the housing element 1 can be achieved, so that a reliable mixing of substances takes place. In addition, the wing elements 12 may have sharp areas to not only mix the granules but also to downsize.
    The stirring element 8 may also have a housing closure 9, as shown in Fig. 6. The housing closure 9 can be attached in particular to the cover surface 3, so that no substances can escape from the housing element 1 during a process of thorough mixing by means of the stirring element 8. The housing closure 9 is in particular connectable to one of the holding devices 10 of the housing element 1. The housing closure 9 may also have a filling unit 14 in order to add further substances during the mixing. In particular, binders can be added in this way simply and with little effort. In particular, the filling unit 14 is an opening or a spray head, so that the further substance, in particular a liquid, can either be added, added dropwise or sprayed. In particular, a uniform atomization and distribution can be achieved by the spray head.
    Furthermore, the stirring element 8 has a drive 13. In particular, the wing elements 12 are rotatable via the drive 13, in order thus to allow mixing of the substances within the housing element 1.
    Fig. 7 shows schematically a structure of a granulation plant according to an embodiment of the invention. The granulation system has a first housing element 1a and a second housing element 1b, which are in particular identical to the housing element 1 described above. In addition, the granulation system has a stirring element 8 as described above, which can be inserted into the first housing element 1a and / or the second housing element 1b. Furthermore, the granulation unit has at least one cover element 4 as described above, a first screen element 5a and a second screen element 5b different from the first screen element 5a for screening a content of the housing element 1, a fluid-permeable element 6 for introducing a fluid into the housing element 1 and Filter element 7 for collecting a content of the housing element 1. All of these elements can be assembled according to the modular principle in order to realize different functionalities of the granulation plant.
    The granulation plant has a first station 15, a second station 16 and a third station 17. All of these stations 15, 16, 17 perform different tasks during the granulation process. It is provided that the different stations 15,16, 17 takes place by different composition of the individual elements mentioned.
    The first station 15 serves to carry out a granulation step and / or a sieving step. The second station 16 serves to carry out a drying step. The third station 17 serves to carry out a granulation step and / or coating step and / or drying step. It is provided that the first station 15 is formed by providing the stirring element 8 in the first housing element 1a and / or the second housing element 1b. In the first station 15, moreover, the first housing element 1a is connected to the second housing element 1b for fluid communication. In this case, the first sieve element 5a or the second sieve element 5b is arranged between the first housing element 1a and the second housing element 1b. The first sieve element 5a and the second sieve element 5b are formed as an intermediate bottom which connects a holding device 10 of the first housing element 1a and the second housing element 1b so as to connect the first housing element 1a and the second housing element 1b for fluid communication.
    In the second station 16, a fluid-permeable element 6 and a filter element 7 are arranged on the first housing element 1a and / or the second housing element 1b. The first housing element 1a and the second housing element 1b are preferably connected via a connecting element 19. Thus, a fluidized bed in the second station 16 can be realized by introducing air through the fluid-permeable member 6 into the first housing member 1a and / or second housing member 1b, while through the filter member 7, the contents of the first housing member 1a and / or second housing member 1b is retained when the introduced air leaves the first housing element 1a and / or the second housing element 1b again.
    In the third station 17, a fluid-permeable element 6 and a filter element 7 are arranged on the first housing element 1a and / or the second housing element 1b. In the filter element 7, an injection nozzle 20 for coating material is attached, wherein the first housing member 1a and the second housing member 1b are preferably connected via a connecting member 19, thus enabling the third station to realize a fluidized bed. By the fluidized bed coating can be carried out easily and with little effort.
    In particular, the first station 15, the second station 16 and the third station 17 are not present at the same time. On the contrary, these stations 15, 16, 17 can be produced from the first housing element 1a and the second housing element 1b by different configurations of the first housing element 1a, the second housing element 1b, the cover elements 4, by different steps of the conversion 100, 200, 300, 400. of the first sieve element 5a, the second sieve element 5b, the fluid-permeable element 6, the filter element 7 and the stirring element 8 are produced.
    In particular, the granulation can have the following functions: - Powder dosing - Closing by continuous bottom unit - Mixing by stirrer-top combination - Binder addition by stirrer-top combination - Sieving as an intermediate bottom - Drying through fluid bottom - Filter unit - Add coating material [0037 ] In Fig. 7, the supply and removal of substances is shown by arrows. An air supply 1000, a powder feed 2000, a granulating liquid feed 3000, a coating material feed 4000, an air discharge 5000 and a product dispenser 6000 are shown.
    8 and 9 show schematically different processes in the granule production using the granulation system shown in Fig. 7.
    FIG. 8 shows a schematic sequence of a granule production via a high-speed mixer with subsequent fluidized-bed drying without coating, which proceeds as follows: First, the first station 15 of the granulation plant is used. For this purpose, the first housing element 1a is provided with a cover element 4, so as to form a cup. In this cup different powders are metered. In the embodiment shown in Fig. 8, two different powders are present, which are filled into the cup. In addition, it is shown in FIG. 8 that the stirring element 8 is connected to the first housing element 1a only after the powder has been introduced. In an alternative, the stirring element 8 may already be present during dosing of the powder.
    By placing the stirring element 8 with the housing closure 9, the first housing element 1a is closed. By activating the stirring element 8, the powder is set in motion and mixed.
    Once the powders are thoroughly mixed, a binder is metered in via the filling unit 14 of the housing closure 9 with stirring. This leads to the production of a granulate from the powders within the first housing element 1a. This is followed by a first changeover 100.
    The first conversion 100 takes place within the first station 15 and is used for screening, in particular for wet sieving of the granules. For this purpose, the stirring element 8 is removed together with the housing closure 9 and a first sieve element 5a is placed. Subsequently, the second housing element 1b is placed on the first housing element 1a, so that the first housing element 1a and the second housing element 1b are connected for fluid communication. The second housing element 1 b is also closed with a fluid-permeable element 6. Thereafter, the entire unit is rotated 180 °. After rotation, the lid member 4 is removed. The granules are now on the first sieve 5a.
    In order to start the wet sieving by means of the first sieving element 5a, the stirring element 8 is again used. By placing the stirring element 8 with the housing closure 9 on the first housing element 1a, granules can be set in motion by the wing elements 12 of the stirring element 8. As a result of the movements of the stirring element 8, the granules are screened into the second housing element 1b. The sieved powder thus falls on the lower unit, i. the fluid-permeable element 6.
    After successful screening, a second conversion 100 is performed to generate the second station 16. In the second station 16, the granules, which is located in the second housing element 1 b, are dried. For this purpose, the first housing element 1a and the second housing element 1b are separated to remove the first screen element 5a. In addition, the stirring element 8 is removed with the housing closure 9 and replaced by a filter element 7. Thus, the granulation plant is ready to perform the drying by fluidized bed. For this purpose, the fluid-permeable element 6 is connected to an air supply.
    The fluid-permeable element 6 is, in particular, such a housing closure element that has a plurality of nozzles through which air can be blown into the housing element 1. Thus, within the housing element 1, a fluidized bed can be generated.
    By warm process air, which is introduced via the fluid-permeable element 6 in the second housing element 1b and in the first housing element 1a, the sieved granules are set in motion and dried. At the same time, the filter element 7 prevents the granules from leaving the first housing element 1a and / or the second housing element 1b.
    After the granules have been dried, a third conversion 300 takes place in order to again realize the first station 15. In particular, a dry sieving should now take place. For this purpose, the filter element 7 is removed and replaced by a cover element 4. For dry screening, a second screen element 5b is inserted, which differs from the first screen element 5a. This generated unit is also rotated by 180 °. Now, the fluid-permeable element 6 can be removed and a stirring element 8 are placed with the housing closure 9. The structure is therefore identical to the structure during the wet sieving described above, except for the second sieve element 5b.
    By the stirring element 8, the granules are brought to a uniform grain size and falls through the second sieve 5b in the first housing element 1a. Subsequently, all elements are removed except for the first housing element 1 a and the cover element 4, so that the first housing element 1 a fulfills a function of a cup. The cup now contains the finished granules, which can be provided for further processing. The third station 17 shown in Fig. 7 is not needed in this case.
    FIG. 9 shows a schematic sequence of granule production via high-speed mixer with subsequent fluidized-bed drying with coating, which proceeds as follows: Until the step of the third conversion 300, the sequence is identical as shown in FIG. This means that the first station 15 and the second station 16 are constructed identically prior to the third changeover 300 as in FIG. 8. However, the granulation system is different from FIG. 8 with respect to the first station 15 after the third changeover 300.
    Thus, the filter module 7 is removed for the third conversion 300. The first housing element 1a and the second housing element 1b are separated and then joined together with a connecting element 19, wherein a second screen element 5b is provided between the first housing element 1a and the second housing element 1b. The second screen element 5b is preferably different from the first screen element 5a. The first housing element 1a, which is arranged above the second housing element 1b, is closed by a fluid-permeable element 6. The entire unit is now rotated by 180 °, so that the second housing element 1 b is arranged above the first housing element 1 a. Now, the fluid-permeable element 6 attached to the second housing element 1 b can be removed and replaced by a stirring element 8. A housing termination 9 of the stirring element 8 closes the second housing element 1 b. The granules are therefore located on the second screen element 5b within the second housing element 1b above the first housing element 1a. Thus, the first station 15 is again realized, whereby a processing of the granules with the stirring element 8 is made possible.
    Subsequently, by lowering the stirring element 8 with the housing closure 9, the granules are brought to a uniform grain size. The granules fall through the second sieve element 5b on the fluid-permeable element 6 and is thus in the first housing element 1a.
    After the granules have been collected in the first housing element 1a, a fourth changeover 400 takes place in order to realize a third station 17. For this purpose, the first housing element 1a and the second housing element 1b are separated and then reassembled with the connecting element 19 without the second screen element 5b, the top surface 3 of the second housing element 1b, which is located above the first housing element 1a, after the removal of the stirring element 8 and the housing closure 9 closed with a filter element 7. The filter element has an injection nozzle 20 for a coating material (coating material), so that the coating material can be injected into the first housing element 1a and the second housing element 1b. Thus, the third station 17 is realized, which allows a coating (coaten) of the granules.
    By adding warm process air through the fluid-permeable element 6 and by adding the coating material via the injection nozzle 20, the granules are coated. The granulation plant functions as a fluidized-bed plant, resulting in a low-cost and reliable coating of the granules.
    Subsequently, the finished granules can be output. For this purpose, the filter element 7 and the injection nozzle 20 are removed, instead a cover element 4 is attached to the second housing element 1b. By a 180 ° rotation of the entire unit, the finished granules are transported into the final container and can be provided for further processing. The end container is the second housing element 1b with the cover element 4. The first housing element 1a and the connecting element 19 are removed.
