Filling and emptying process for deep fat industrial fryer - utilises single channel for liq. transfer in both directions by displacement of piston, with oil filtered before returning to tank

摘要

Frying oil is stored in a cylindrical tank with a piston whose displacement fills and empties a vessel via concentric forwardand return channels terminated at an inlet and outlet. The inlet valve opens only under external pressure. The outlet is equipped with a filter having a handle for withdrawal. The vessel encloses a frying-pan with a grid base and a stainless steel deflector coextensive and integral with the door, which is opened and closed by jacks. Oil is recycled to the tank via a readmission aperture with a valve opening only under internal partial vacuum. The method may be used for feeding an industrial frying vessel.
