4. Setup
4.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect the machine for any signs of shipping damage. If damage is found, do not operate the machine and contact your supplier immediately.
- Ensure all listed components are present.
4.2 Assembly (if required)
The Zipper ZI-GRM1100 typically requires minimal assembly, primarily attaching the support legs and wheels. Follow these general steps:
- Attach the support legs to the main body of the plucker using the provided hardware. Ensure all bolts are securely tightened.
- Mount the transport wheels onto the designated axles on the support frame.
- Verify that the machine is stable and all connections are secure before proceeding.
4.3 Placement and Connections
- Place the plucker on a firm, level surface in an area with good drainage, as water will be used during operation.
- Ensure the location is near a suitable electrical outlet (230 V, 50 Hz) and a water source.
- Connect a standard garden hose to the water inlet connection on the side of the drum. Ensure the connection is tight to prevent leaks.
- Plug the power cord into a grounded electrical outlet.
5. Operating Instructions
Follow these steps for safe and effective poultry plucking:
- Poultry Preparation: Ensure the poultry has been properly scalded. The recommended water temperature for scalding is approximately 55°C (130°F). Proper scalding loosens the feathers, making them easier to remove.
- Load Poultry: With the machine turned OFF and UNPLUGGED, carefully place up to two scalded birds into the plucking drum.
- Start Water Flow: Turn on the water supply to the plucker. A continuous flow of water helps to rinse away feathers and debris during operation.
- Start the Machine: Plug in the machine and turn on the power switch. The drum will begin to rotate, and the rubber fingers will start plucking the feathers.
- Plucking Process: The plucking process is typically very fast, often completed within 15 seconds for properly scalded birds. Observe the poultry to determine when most feathers have been removed.
- Stop the Machine: Once plucking is complete, turn off the power switch and unplug the machine. Turn off the water supply.
- Remove Poultry: Carefully remove the plucked poultry from the drum.
- Inspect and Finish: Inspect the poultry for any remaining feathers and remove them manually if necessary.
Note: Over-plucking can damage the skin. Monitor the process closely to achieve optimal results.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Zipper ZI-GRM1100 plucker.
6.1 Cleaning
- After Each Use: Immediately after each plucking session, disconnect the power and thoroughly rinse the inside and outside of the drum with water to remove all feathers and debris. The stainless steel drum is designed for easy cleaning.
- Use a brush if necessary to dislodge stubborn debris from around the rubber fingers.
- Ensure all water drains completely from the machine to prevent stagnation and bacterial growth.
- Wipe down the exterior surfaces with a damp cloth.
6.2 Inspection
- Rubber Fingers: Periodically inspect the rubber plucking fingers for signs of wear, cracking, or damage. Worn fingers can reduce plucking efficiency. Replace any damaged fingers promptly.
- Electrical Cord: Check the power cord for any cuts, fraying, or damage. Do not use the machine if the cord is compromised.
- Motor: The asynchronous motor is designed to be maintenance-free. Do not attempt to open or service the motor yourself.
6.3 Storage
- Store the plucker in a clean, dry place, protected from extreme temperatures and direct sunlight.
- Ensure the machine is completely dry before storing to prevent corrosion.
