Definitions
- the invention relates to a fluid bed apparatus with integrated spray drying and a method for its use.
- the invention also relates to a process for producing spray-dried powder material, the product properties of which can be varied in a targeted manner depending on the further use.
- granules are usually produced by spraying a solution or a suspension of one or more components into a spray tower charged with hot gas.
- the liquid components evaporate in the hot gas stream and solid particles are formed, which are more or less statistically shaped.
- Granulation in a fluidized bed is also known, in which the process air stream flows through a specially shaped inflow floor and thereby produces a fluidized bed of solid starting material.
- the spray liquid enters the swirl chamber in a finely divided manner through a nozzle system.
- the swirling particles are wetted, the surface is dissolved and the particles stick together. Solid is continuously removed at the end of the fluidized bed.
- a smaller amount of solids is fed in at the entrance and the spray liquid is finely distributed.
- a filter system ensures that no dust leaves the fluidized bed and that granulate particles with a minimum size are only removed at the outlet. Solid particles which are more or less statistically shaped also form in such a fluidized bed.
- a special embodiment consists in that a spray drying unit (B) is located vertically above a subsequent fluidized bed in a spray tower.
- the liquid medium is a solution, a dispersion or a suspension.
- a special variant of the method consists in that the recycled powdery material is crushed before the recycling.
- a gas selected from the group N 2 and C0 2 can be used as the spray gas, as the carrier and heating gas, air or an inert gas.
- the gas can be circulated, in which it is freed of particles by filters or with the aid of dynamic filters and is again fed or heated to the spray nozzles and introduced into the fluidized bed.
- liquid media used at different points in the system can have different compositions.
- the present object is achieved in particular in that particle sizes between 50 to 1000 ⁇ m can be set in a targeted manner by varying the parameters, spray pressure, liquid quantity, returned powder quantity, hot air flow and temperature of the hot air.
- the system is initially charged with powdered starter material via the filler neck (3).
- An air flow is generated in the spray drying room via the chambers (1).
- the introduced starter material is fluidized by this air flow and moves in the direction of the discharge flap (F).
- the powder flow receives this direction of movement when the air flow is generated by a corresponding perforation of the Conidurêt.
- the fluidized product can be opened by simply opening the lock flaps
- Discharge (F) At this point in the system, devices are created which either allow the product to be fed into a powder metering system or via a flight conveyor to the spray drying unit.
- An overflow (8) for the finished product is located at the discharge via the powder dosing system.
- the fan (E) of the spray drying unit serves both as a conveying means for the product and as a comminution unit for powder material to be returned.
- Returned powder material of the return line (9) is combined with the corresponding media liquid (5) spray air (6) and hot air (4) by the special design of the spray drying nozzle.
- the resulting powder or granulate is taken up by the fluidized bed and is transported on as described above.
- three granulation nozzles (C), as shown in Figure 1, one or more spray nozzles or spray drying nozzles or only one, two or more than three granulation nozzles can be attached to the corresponding point in the system. These additional nozzles can be located directly at the beginning of the fluid bed or moved further back.
- the choice of the location at which the powder material originally formed is sprayed once or several times depends, among other things, on the residual moisture content of the desired product. It goes without saying that a product with a particularly low residual moisture after the last spraying requires a longer residence time in the fluidized bed than one with a longer one.
- the various nozzles can be used to apply different compositions to the particle surfaces already formed, so that particles with a layered structure can be obtained. However, it can also be used to achieve a more uniform grain size distribution.
- system according to the invention can be operated not only with air as the carrier medium. It is also possible to use an inert gas, such as e.g. B. nitrogen, or to drive with carbon dioxide gas.
- the system is designed so that the parameters liquid quantity, spray pressure, recirculated powder quantity, hot gas quantity, hot gas temperature, warm air quantity, warm air temperature can be individually regulated. Therefore, the properties of the end product can be adjusted in terms of moisture, particle size and particle size distribution by the amount of powder returned, the amount of liquid fed in and the spray pressure.
- powdery products with particle sizes between 50 and 1000 ⁇ m can be produced in the system described.
- the particles can consist of a single chemical substance or have a layered structure of different substances or, depending on the chosen process parameters, have a more or less crystalline or predominantly amorphous structure, in the latter case the particles both from one and from a mixture can consist of different components.
- the formation of the particles can be particularly controlled by a spray nozzle integrated in the system, which is suitable for producing spray-dried granules.
- a spray nozzle integrated in the system, which is suitable for producing spray-dried granules.
- a corresponding embodiment of such a spray nozzle is shown in FIG. 2.
- This spray nozzle is a spray system that consists of a two-substance spray nozzle [(1), (2), (3)] that can be heated with hot water, which in turn has a coaxially arranged powder return (4) and a hot gas flow (5 ) Is provided.
- this spray system is that the powder comes into contact with the liquid droplets generated by the atomizing air directly at the outlet and is granulated or agglomerated. So that the granules do not stick together and the surface moisture can be removed, the spray and powder distribution is enclosed in a hot gas stream, where the energy required to evaporate the liquid is directly converted. After-drying takes place in the fluid bed.
