Abstract
A pneumatically operated egg injection machine includes a sealed frame structure with a pair of in line parallel tracks through an injection section and a transfer section in series. An injection assembly includes a plurality of injectors gripped in a support plate to simultaneously inject vaccine into the same injection region irrespective of egg height and orientation. Fluid delivery systems meter prescribed vaccine dosages to the injecting needles with reduced turbulence, friction, heat and residence time to increase the delivered titer to the injected eggs. A transfer assembly lifts the injected eggs by causing a reduced pressure around the injection hole while maintaining the injection hole at atmospheric pressure. The injection assembly is sprayed with a sanitizing solution at the same time that the injected eggs are moved from the injection section to the transfer section.
