will. In addition, the recess formed in this way with the filter offers a slight oil filtering, since now, after the oil has been removed from the container, the oil is cleaned by the Filter through it can be poured back into the container, so that after filtering, the device can be used again immediately is available. We recommend the filter made of a filter fleece and one on one side of the Filter fleece arranged mat having carbon dust built up, since good filtering is achieved in this way. In addition, an odor absorption of the oil vapor can be achieved via such a filter even during deep-frying, see above that these deep-fryers are in use with almost no odor nuisance.

To hold the fleece securely in the recess of the lid, it is recommended that the pot-like recess with a to close the insert provided with openings. It is advantageous here if the insert is rotatably arranged in the recess is, wherein the insert has at least one concentrically arranged annular contact surface with the filter, there over the annular contact surface during the rotary movement serving to fasten the insert a shifting or shifting of the fibrous filter fleece is avoided. Advantageous it is when the cover is provided with brackets arranged on two opposite sides of the recess, which extend into the recess in some areas, the annular insert having a flange on its circumference, which in different stages. This arrangement allows the insert to be securely held on the cover in which the flange is brought under the brackets. In addition, the various levels ensure that the use Filters of different strengths can also be held in the recess. The use with a provided as a handle serving cylindrical part, this
