ABSTRACT:
A device for cracking open an egg is shown, having 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 shown.
