Polishing & heel filter

A range of pulse tube filters are used as polishing or safety filtration of oil/bleaching clay upon completion of the main filtration process.
In batch filtration for different types of oil, the unfiltered rest volume (heel) should be as little as possible. For this reason, the polishing filter can be used to minimize the unfiltered rest volume.
At this stage, the flow rate is less critical. More important is the amount of the unfiltered rest volume, which together with the solids concentration, determines the size of the after filter.
Polishing or safety filtration is the most common final step in nearly all edible oil filtration processes.
