ABSTRACT:
A filter drying apparatus for cylindrical-type filter units having a frame and an adjustable means for rotating the filter unit at regulated set speeds, the area in which the filter is rotated being surrounded by a casing. Within the casing, adjacent the bottom thereof, is a freely rotatable lower cone-shaped member for supporting one end of the filter, and directly above the lower cone is a similar vertically adjustable cone-shaped member connected with the filter rotating means. These cone-shaped members are adapted to engage the filter unit, one at each end thereof, the cones being tapered at an angle of approximately 60.degree., and constructed of a semi-elastic material such as rubber, or a suitable plastic composition. Both cone members are tapered outwardly and downwardly from their tops, the lower cone member engaging the inner edge of the filter unit, and the upper cone member engaging the outer edge of the opposite end of the filter unit to rotate the same.
