Beschreibung
Zusammenfassung:	The invention relates to a method for producing an anhydrous powder having a calcium nitrate content of between 92 and 99.9 weight %, a water content of between 0.1 and 8 weight %; and a particle size of between 0.05 and 1.5 mm, wherein the method comprises the step of subjecting a calcium nitrate solution having a water content of between 70 and 15 weight % and a calcium nitrate content of between 30 and 85 weight % to a drying step in an industrial turbo-dryer, resulting in the anhydrous calcium nitrate powder. The invention furthermore relates to such an anhydrous calcium nitrate powder and the use of an industrial turbo-dryer to produce such anhydrous calcium nitrate powder.
