Abstract: Frying ingredients are fry-cooked within a frying oil layer used for fry cooking, under the conditions meeting a relationship of HA/SA1/2=0.6 to 3.5, where SA denotes the surface area of the frying oil layer and HA denotes the height from the bottom to the surface of the frying oil layer.

Abstract: An apparatus for loading a powdered or granular material comprises a cylindrical chute, which is mounted in a manner to be movable in a vertical direction and through which passes the loading material, a screw type extruder for extruding the loading material from inside the chute, the extruder being mounted to a lower open end portion of the chute and capable of closing the lower open end of the chute, driving means for driving the extruder, a wire having one end fixed to the tip of the chute and having the other end fixed to a wind-up device through pulleys, and a load cell for detecting an amount of change in the thrust received by the extruder from the powdery or granular loading material. The wind-up device is operated on the basis of the value detected by the load cell.
