Abstract
Abstract A device for deep frying particularly a device for frying potato chips in oil comprises a trough for the frying oil having a ledge on at least one side thereof. A furnace casing encloses the furnace heating space below the trough and it includes a vertical wall which abuts against the edge of the ledge and which is sealed to the ledge such as by welding. A cover encloses the top of the trough and overlaps the exterior surface of the vertical wall. The cover is secured to the vertical wall such as by securing bolts in a manner defining a drip space for the cooking oil which collects on the cover and runs down along the side thereof through the drip space. A drain device is provided on the exterior of the vertical wall in a position to receive the drip oil which may be recycled to the cooking trough.
