Abstract: A deep fryer apparatus particularly suitable to home use with a rotatable basket rotating within tray. Both the basket and the tray can be removed from a fixed tray within the housing. The axis of rotation of the basket is greatly inclined with respect to an oil bath contained in tray, so that the food contained in the basket is cyclically and progressively immersed in the oil bath. The bath is heated by adequate heaters, and the apparatus is monitored by control devices.The new deep fryer features high overall performance and low operating costs. This is due in particular to the small quantity of oil needed to form the oil bath, which is about one-half what is generally necessary, and to the reduced cooking time required as a result of the progressive and repeated elimination of food moisture.
