The water temperature should be within 75 degrees Celsius and not lower than 72 degrees Celsius.

Preparation is scalding them in 140 degree water before putting them in the plucker. We submerge them in scalding water for 7 to 10 second intervals until you can easily pull out a few pin feathers which it is then ready for the plucker. Don't scald it too long or you will start to cook the meat.
