Abstract

Methods and apparatus for forming an opening in a shell of an avian egg such that the potential for cracking is greatly reduced are provided and comprise moving a punch (26) through an egg shell (20) at speeds equal to or greater than thirty inches per second. Punches may be driven via various devices including gravity-assisted devices (40), spring-assisted devices (50), solenoid-assisted devices (60), and fluid-assisted (e.g., compressed air, compressed nitrogen, liquid, etc.) devices (70). The shell of an egg (20) may be pierced without causing cracking by hurling one or more small projectiles (80) at the egg shell (20) at speeds in excess of thirty inches per second. A punch (26) may be mounted on a piezoelectric actuator (90) configured to vibrate at frequencies in a range of between about 1,000 Hz and about 100,000 Hz. These frequencies effectively cause a punch (26) to move at speeds in excess of thirty inches per second.
