English Abstract

The present invention relates to an improved
hatcher structure which is more efficient than
conventional hatchers and which is easier to construct,
operate and service. In particular, the hatcher of the
present invention utilizes a restricted area, high
pressure zone of air to control the exhaust of air from
within the chamber and, in turn, control the intake of
cooler external air into the chamber and the mixing of
that air with the internal air. To achieve this control,
the hatcher of the present invention further utilizes a
mobile environmental adjustment system and an alignment
mechanism which ensures precise and consistent placement
of the environmental adjustment system within the chamber.
In addition, the present invention employs an improved
frame post and doorway seal which facilitate construction,
operation and maintenance and which promote internal
environmental consistency.
