4. Operating Instructions
Follow these steps for efficient poultry plucking.
- Preparation of Poultry: Ensure the poultry is properly scalded before plucking. This loosens the feathers for optimal removal.
- Start the Machine: Turn on the machine using the power switch. The drum will begin to rotate.
- Activate Water Supply: Open the water supply to the built-in irrigation ring. The continuous water flow helps to rinse away feathers and dirt during the plucking process.
- Insert Poultry: Carefully lower the scalded poultry into the rotating drum. The 158 replaceable rubber fingers will efficiently pluck the feathers and remove dirt from the skin.
- Monitor Process: The plucking process is typically very fast, often within seconds. Monitor the poultry to ensure all feathers are removed.
- Remove Poultry: Once plucked, carefully remove the poultry from the drum.
- Shut Down: Turn off the water supply, then turn off the machine.

5. Maintenance and Cleaning
Regular cleaning and maintenance ensure the longevity and hygienic operation of your plucking machine.
- Daily Cleaning: After each use, disconnect the power supply and water. The quick-change tub allows for simple and fast cleaning. Rinse the stainless food-grade tub thoroughly with water to remove all feathers and debris. The stainless material inhibits bacterial growth and is easy to clean.
- Rubber Fingers: Periodically inspect the rubber fingers for wear or damage. Replace any worn or missing fingers to maintain plucking efficiency.
- Motor: The motor is designed to be maintenance-free. Keep the motor housing clean and free from debris. Do not attempt to lubricate or open the motor.
- Storage: Store the machine in a dry, clean place, protected from extreme temperatures and direct sunlight.
