Abstract
A method for the adsorptive purification of vegetable and/or mineral oils and fats works with a multi-stage counter flow process. At least a part of the solid phase leaving the first separating stage is mixed in batches or continuously with a part of the purified oil or fat leaving the last separating stage. The mash thereby obtained is fed to a subsequent filter.
