The equipment used consisted of a Sebelin heating battery, with
capacity for six Soxhlet extractors. Its operating principle is the contact between the solvent and the oilseed mass. The solvent that is
stored in the heated balloon evaporates and condenses over the
solid material. When it condenses, it exceeds a certain volume and
flows back to the balloon along with the extracted oil content,
where it is heated and evaporated again
