Abstract: An egg incubator comprises on a front face, at least one door for the introduction thereinto of carriages with drawers containing eggs. Directing-distributing means direct a principal flow of stirring air towards said front face through which at least three series of carriages, of which one is a central series, are introduced into the incubator, and distribute by division, a part of said principal flow onto the series of carriages arranged on both sides of said central series of carriages. Moist air distributing means are constituted by a sort of inverted U whose downwardly directed arms are beneath the flow of stirring air, on the return of the latter, so that said moist air emerging from slots formed in said arms is drawn along by this return flow. It includes a vertical bank of ventilators, and a fresh air intake and temperature regulating unit associated with said vertical bank.

Abstract: The invention relates to an egg incubator of the tunnel type comprising an entrance at one end and an outlet at the other and two sets of rails receiving two rows of trolleys carrying egg drawers which tip under the action of tilting parallelograms.According to the invention, two sliding panels fitted with fans are each placed opposite a different row of trolleys, one at the entrance end, the other at the outlet end, in such manner as to create a longitudinal flow of stirring air, reversed by displacement of the panels during each charging or discharging.
