PCT No. PCT/SE87/00403 Sec. 371 Date Mar. 2, 1989 Sec. 102(e) Date Mar. 2, 1989 PCT Filed Sep. 8, 1987 PCT Pub. No. WO88/01899 PCT Pub. Date Mar. 24, 1988.A method for application in conjunction primarily with so-called rotating filters of the kind which include a substantially cylindrical filter tube (1) which is provided with a permeable wall and which is sealingly journalled at preferably two axially spaced locations, preferably at the ends of the tube, and which is arranged for rotation about its longitudinal axis in a filter jacket (2), wherewith material to be filtered, the so-called feed, is supplied to a space or chamber (11) located between the filter jacket and the filter tube, and the filtered substance, the filtrate, being tapped-off from the interior of the filter tube. The method is particularly characterized by sealing and journalling the filter tube (1) in a manner adapted to substantial changes in temperature in the filter tube and that facilities are provided for sterilizing the filter. When applicable, the bearings and seals can be sterilized and lubricated and cooled by means of sterilizing media, and, when applicable, the filter tube (1) is caused to rotate at relatively high speeds. The invention also relates to a device for carrying out the method.
