Abstract (en)
[origin: WO02073108A1] The invention relates to a method for producing dry plant extracts in a gentle manner. A liquid plant extract is introduced into a vacuum drying installation comprising a multi-limb stirring machine having its own drive and extending through a cylindrical mixing and drying chamber, and a chopper which rotates by means of a stator. The liquid plant extract is dried at a jacket temperature of between 20 DEG C and 50 DEG C, a product temperature of between 20 DEG C and 40 DEG C, a pressure of between 0.5 and 1,000 mbar, a stirring rotational speed of more than 0 to 10 Upm, and a chopping rotational speed of between 200 and 800 Upm. The invention is characterised in that the liquid plant extract is sprayed into the mixing and drying chamber by means of at least one nozzle above the filling level of said mixing and drying chamber, when there is a pressure difference of > 100 mbar between the drying chamber and the reservoir. The nozzle(s) respectively produce a drop atomising cone >/= 30° in at least one spatial direction, the average drop size of the sprayed liquid plant extract being </= 300 µm and the transporting capacity of the nozzle(s) being smaller than or equal to the evaporative capacity of the drying installation.
