Abstract
Offal from a poultry hatchery, including new-born chicks, is processed into a form suitable for rendering or disposal as land fill by dumping same into a device including a pair of elongated, generally cylindrical, counter-rotating rollers. Each roller has external longitudinally extending corrugations which mesh with the corrugations on the other roller. The corrugations are configured so that, as the offal passes between the counter-rotating rollers, new-born chicks and live, unhatched embryos are killed instantly and other debris, such as egg shells, are crushed into a smaller form.
Claims5
A method for processing offal from a poultry hatchery, including new-born chicks, into a form suitable for rendering or disposal as land fill comprising the steps of
- providing a pair of elongated, generally cylindrical rollers, each roller having an outer periphery including a plurality of longitudinally-extending corrugations which are circumferentially spaced at uniform intervals and mesh with, but do not contact corrugations on the other roller as the rollers are counter-rotated, the corrugations having peaks and valleys which are configured so that the body of a new-born chick can fit into the space between the valley of a corrugation on one roller and the peak of a corrugation on the other roller just prior to meshing,
- counter-rotating the rollers,
- introducing the offal into the nip between the rollers,
- passing the offal between the rollers to instantly kill the new-born chicks therein and to crush other debris into smaller form, and
- discharging the processed offal from the rollers into a means for conveying same to a remote location.
