ABSTRACT:
Apparatus has a rotary drum provided with a heating jacket therearound. The drum is mounted on a base pivotally supported on a pedestal. The base can be caused to take different orientations so as to enable the drum to take different attitudes. While the drum is in a vertical position, a mixture of fine particles and a liquid is supplied into the drum through a supply passage formed axially in a rotary shaft which extends into the drum rotatably and axially slidably relative to the drum. The mixture is filtered through a filter disposed in the drum. Filter liquid is discharged to the outside. The particles are prevented from passing through the filter and remain in the drum. Thereafter, the particles are heated and dried by a heating jacket on the drum while the drum is caused to assume a horizontal position and being rotated. The drum is then inclined such that the initially upwardly directed end thereof is directed obliquely downward. Thereafter, an agitating blade and sweeping blades on the inner end of the rotary shaft is rotated and shifted axially, whereby the dried particles are agitated and swept, to be discharged to the outside.
