Incubating egg life / death judgment device used in the hatching machine

摘要

PROBLEM TO BE SOLVED: To provide an egg life / death determination device during hatching which measures an eggshell temperature using a contact thermometer in an egg hatcher. An in-hatching egg life-and-death determination device 1 used in an incubator determines an internal state including at least alive-and-death of an in-hatching egg E measured by a contact thermometer 4 based on eggshell temperature information and environmental temperature information. judge. The eggshell temperature information is obtained from N (N is an integer of 2 or more) contact thermometers 4 that measure the eggshell temperature of the in-hatching egg E in the setter tray T accommodating a plurality of in-hatching eggs E. The environmental temperature information is obtained from M ambient temperature thermometers 5 (M is a positive integer smaller than N) arranged in the vicinity of the contact thermometer 4.
