Full textThe humidity of the inlet air is one of the largest problems within granulation pro-cesses in the pharmaceutical industry. Is it not possible to condition the inlet air in reference to its absolute moisture, there often only remains the alternative to stop production. One topic of the existent dissertation deals with the question wether it is possible to produce granulates of comparable characteristics independent from the conditions of external air like temperature, pressure and moisture. On the other hand it is examined which influence several process and material parameters or rather their variations have on the final product and what that means for an automation of the process or the specification of production plant control and regulation. Based on the mass balance of a fluidized bed granulation the effects of different process and material parameters on a standard granulate are proved. On the one hand the re-sults of the different test series attest the reproducibility of granulate characteristics based on the calculations of the critical spray rate. Otherwise they point out the in-fluence of several process and material parameters on the quality of the end product. Based on these results important perceptions for an automated control system and regulation of the production plant can be deflected and adequate requirements for every single process parameter as well as for supervising sensors can be defined. The calculation of the practicability of batches is a significant foundation for a deci-cion in reference to batch planning and provides a basis for scaling up processes. Apart from that the algorithms are able to adapt the process parameters to the daily and annually variations of the inlet air. Theoretical studies to “adjustment of inlet air conditions” show, that thanks to the calculations it is possible to bring the free mois-ture to a defined level during spraying. This part of excessive water is responsible for agglomeration and therefore for the reproduction of granulates. The existing disser-tation represents an important step to an automated fluidised bed granulator. It shows approaches for possible proceeding and provides precious indications for re-quirements of measuring sensors as well as for control systems and regulation units

Full textThe aim of the present work was the implementation of a mass balance of a fluidized bed granulation process. By the use of an extensive instrumentation of a laboratory-scale fluidized bed granulator that operates with a top-spray methode (Glatt GPCG 1.1, Binzen, Germany) it is possible to measure the relative humidity, the temperature and the absolute pressure of the fresh as well as of the outlet air and in addition the volume flow. The calculation of the density of moist air allows the transfer to mass flows of air and of water. The current mass of water inside the granulation chamber is gathered by the difference of water transferred into and transported out of the granulator. The very precise determination of all relevant parameters is a prerequisite for such a kind of mass balance calculation. The relative humidity is measured with capacitive humidity sensors, which were subjected to a newly developed calibration methode. As the response time of the humidity sensors is a crucial process parameter, reference measurements with acoustic humidity sensors are conducted. The measurement of the volume flow of the fresh air is realized by an undamped propeller-type flowrate meter. For the calibration of this sensor air flow velocity profiles inside the tube are recorded with a hot-wire anemometer under several constant volume flow conditions. The integration of the air flow velocity over the whole tube cross section results in the effective volume flow. Turbulent flow is observed throughout the machine at each point of time. As condensed water can not be recorded by the sensing elements, it is a precondition for the mass balance calculation that the complete mass of water is in its gaseous state at the zone of the humidity sensors. By temperature-measurements at the wall of the tubes and the calculation of the dew point of the outlet air a water-condensation at this region can be excluded. By application of the mass balance calculation it can be shown that the mass of water inside the granulation vessel increases continuously during the spraying phase, to return to the initial value during three different drying stages. The results presented in this thesis provide the prerequisites for a comprehensive control system for fluidized bed granulators as well as the according granulation processes
