A viscous solution of gum resin with about 50% water has to be concentrated without changing
the quality of the solved material and by reaching a reasonable bulk density. On a double drum
drier, 120 mm diameter and 150 mm length with variable space, revolutions and surface
temperatures between 150 and 170°C, 50 kg/nrh of solid material and a film thickness of 0.5
mm could be obtained. The bulk density of 0.18 g/cm3 by producing a powder.
