ABSTRACT:
A process and system of immersion poultry scalding employs counterflow recirculation of scald liquid in a counterdirection to that of the travel of the poultry at least at the bird exit station of the immersion tank. The liquid removed from the tank is filtered and cleaned, sanitized as it is superheated and heats make-up water added to the system to scald temperature before it is returned to the immersion tank. Immediately before reaching the exit station, the conveyor may be arranged for lifting the birds at least partially out of the scald liquid allowing the liquid in the bird feathers to drain before the birds are again immersed in the recirculated liquid at the exit station.
