At the end of the evisceration line, carcasses have to be cooled and the cheapest system is the water chiller.

This system uses cold water: basically, birds are unloaded into the machine, which is equipped with a "screw" conveying them towards the exit; during this phase birds bathe in water which is maintained cold by means of ice or of a cooling system.

At the machine exit, birds move on to a dripping filter and possibly to a dripping/drying chain for an excellent final product.
