Abstract:
This consists of the preparation of powdered still slops from concentrated liquid still slops dried and converted into a powder in a conventional dryer (1) and then fed to a powder collecting cyclone (4), featuring at the lower outlet aperture of the collecting cyclone (4) a circular or snail-shaped or logarithmic spiral-shaped device (7) fed with a cool, dry air draught which generates a downward suction effect counter to the upward suction effect of the collecting cyclone (4), bringing about the falling and separation of the powder from the draught of hot air which carries the same. The cool, dry air carries the powder to the exterior for bagging, and the hot air exits upwards via the collecting cyclone (4) towards the flue (6), using a device for the recovery of the heat which it still bears as much as possible.
