Abstract
An improved cleaning apparatus and method is provided for cartridge filters in a fluid bed processor. A cleaning solution duct is coupled to the air pulse tube so as to supply a mixture of pressurized air and cleaning liquid to the inside of the filter cartridge. The pressure forces the cleaning solution and air outwardly through the filter cloth to remove particles from the interstitial pores of the cloth. The cleaning liquid also flushes the interior and the exterior surface of the cloth. The lower end of the filter includes a cap which is normally closed, and which can be opened to allow drainage of cleaning liquid from the interior of the cartridge filter.
