Abstract: An edible oil cleaner wherein a perforated plate is provided to define a filtering zone within a filter housing, a portion of a filter web paid out of a roll thereof pivotably supported in the housing is disposed to lie over the perforated plate, the web is inserted at its downstream part between nip rollers to be movable when subjected to a rotational force of the nip rollers, and a motor for rotating the nip rollers is intermittently energized in response to a detection of deterioration in the filtering function of the filter web portion on the perforated plate, whereby impurities are continuously automatically filtered off from the edible oil introduced into the filter housing to effectively prevent the oil from being oxidized and to remarkably improve its durability.
