  • Publication number: 20080160145
    Abstract: A device for cracking open an egg is disclosed, comprising egg-size sensing means for determining the size of an egg positioned in the device, thereby providing for automatic calibration of the device to the specific size of an egg to be cracked. The calibration determines how much would the distance between the piercing members and the imaginary longitudinal axis of the egg be reduced before the piercing members stop their advancing towards the egg and start moving apart for cracking its shell open. The device can thus open eggs of different sizes, e.g. having widths between 40 and 50 millimeters, accurately without requiring special preparation or manual calibration. A method for cracking open an egg based on said device is also disclosed.

  • Patent number: 4980183
    Abstract: A method and apparatus for preparing a plurality of whole deviled eggs. The eggs are first oriented and stored collectively in a refrigerated area for a prolonged period of time in order to cause the egg yolk to float to a select side of each egg. The eggs are preferably oriented within a container turned upon its side to cause the sides of each egg to face upwardly. An egg carton is but one example. In this manner the egg yolks rise against the upward facing side. The oriented eggs are then steamed in a specialized platter to facilitate the hard cooking of the egg white in the preselected position. The egg yolk is then removed from the peeled egg through the thin portion of egg white exposed thereon. A whole deviled egg is then prepared by removing the egg yolk and stuffing the remaining whole egg with a preselect mix. The specialized platter is then used as a serving tray, wherein the bottom of each egg is flattened to prevent the egg from easily rolling over in the user's plate.

  • Patent number: 4308290
    Abstract: Peeling of the shells of boiled eggs is realized continuously, promptly and simply by introducing the boiled eggs into a cylinder through which water is flowing, the cylinder performing circular movememt about a substantially horizontal axis with the magnitude of the circular movement increasing gradually from an initial portion towards a terminal end portion. The boiled eggs are firstly made to collide with the inner surface of the cylinder by small circular movement of the cylinder, and rendered more elastic with the eggshells of fine fragments to the degree that the shell membrane remains unbroken. Next, the shell membrane is broken by applying a whirling water stream and a centrifugal force generated by large circular motion. The boiled egg contents are then separated from the eggshells so smoothly as to be slipped out of their shells.
