KNAThe challenge
Poultry processors need a repeatable way to prepare chickens and ducks for plucking without relying on manual temperature checks or uneven scalding.

Our response
KNA developed a gas-fired stainless steel scalder with PT100 temperature sensing and a REX-C100 controller to hold the water at the selected temperature. A gear-and-chain agitator creates gentle water movement that helps open feather follicles and shortens plucking preparation time.
Technical configuration
- 01water tank - stainless steel plate
- 02agitator - stainless steel plate
- 03hopper - stainless steel plate
- 04support frame - stainless steel hollow section
- 05transmission - gear and chain
- 06drain - 1.5 in
- 07drive - 1/2 HP geared motor
- 08temperature sensor - PT100
- 09temperature controller - REX-C100
- 10actuation - electric igniter and electric gas valve
- 11burner - gas
Results Achieved
The machine delivers repeatable poultry scalding for chickens and ducks, with more consistent water temperature, easier feather removal, and a production capacity of up to 100 birds per day.
