The present invention refers to a process for preparing a powder comprising the steps of providing at least one first component being in liquid form at ambient temperature, in particular having a viscous liquid consistency, such as for example an oil or having a waxy consistency at ambient temperature, in particular a component which is a solid or semi-solid at ambient temperature and which has an onset of melting in the temperature range from 15 0C to 40 0C, providing at least one second component having a melting point or melting range in the range from above ambient temperature to below the degradation temperature of said first component, in particular in the range from above ambient temperature to 120 0C, more in particular in the range from >40 °C to 120°C, even more in particular in the range from 50°C to 120°C, even further in particular in the range from 55°C to 120°C, forming a homogenous liquid mixture comprising said at least one first component and said at least one second component by stirring and heating the mixture to or keeping the mixture at a temperature in the range from above the melting point or melting range of said second component and below the degradation temperature of said first component, in particular in the range from above the melting point or melting range of said second component to 120 0C, transferring the liquid mixture to at least one spray congealing unit by at least one transfer unit, which is adapted to keep the mixture in its liquid form during its transfer, spray congealing said mixture, and isolating the powder obtained upon spray congealing. Further, the present invention refers to a process for the preparation of a solid dosage form comprising the powder resulting from the above process.La présente invention concerne un procédé de préparation dune poudre comprenant les étapes consistant à fournir au moins un premier composant qui soit sous forme liquide à température ambiante, ayant en particulier une consistance liquide v
