Bowl shaped basket with a vertical rotating axle at the outside bottom center, equipped with a chip charging pipe, whose charging mouth opens within and at the basket bottom center with a gap, the inner surface of the bowl is so formed that the angle between the tangent to the surface and the rotating axis decreases as the diameter of the bowl, until to almost zero, or even minus at the brim. The time, oil wet chip is dispersed off out of the upper brim, can be taken as long enough, inversely as the rate of chips discharging. The basket is composed of rings each with a quadrilateral or trapezoidal section and of successibly increasing diameters, spot welded together one by one with a outwards divergent slit. The slit is never blocked by chips, and if chips might happen to block the entrance of the slit within the bowl, they can easily be taken off.
