Combined Poultry Scalding & Plucking Machine

Product Introduction: Combined Poultry Scalding & Plucking Machine

I. Product Overview

The combined poultry scalding and plucking machine consists of a self-discharging mixing scalding tank and a small plucking machine. It is mainly used for scalding and feather removal during poultry slaughtering. This product is especially suitable for small-scale processing plants, farmers’ markets, and individual operators.

Made of stainless steel, the product features beautiful appearance, economical durability, energy saving, and stable performance. It has been well received by domestic and international customers since its launch.

II. Product Combinations

Two combinations are available to meet different user requirements:

The following introduction is based on Combination 1 (Self-discharging mixing scalding tank + Small 9-roller plucking machine) .

III. Self-Discharging Mixing Scalding Tank

1. Structural Features & Working Principle

The scalding tank is equipped with steam heating pipes and electric heating devices at the bottom. For electric heating, thermal oil is used as the medium – the electric heating tubes heat the thermal oil, which then heats the water in the tank. For steam heating, the water is heated directly through steam pipes.

A main shaft with rubber bars and paddle-type lifters is installed in the middle of the tank. The operation is controlled via the electrical control panel:

• Main shaft rotates counterclockwise (scalding mode) : The poultry is scalded. The paddle-type lifters and rubber bars stir the water to ensure uniform scalding temperature.
• Main shaft rotates clockwise (discharging mode) : The scalded poultry is flipped out of the tank by the paddle-type lifters and transferred into the small plucking machine for feather removal.

IV. Small 9-Roller Plucking Machine

1. Structural Features & Working Principle

The small 9-roller plucking machine (commonly called “small 9-roller”) consists of a frame, plucking rollers, drive unit, electrical control box, discharge chute, and feather collecting hopper. It is especially suitable for small-scale poultry slaughterhouses and individual operators.

The roller structure features a central main shaft with eight driven rollers arranged in a C‑shape around it, all driven by a single power source. Since the main and driven rollers rotate in the same direction, different sprocket sizes are used to adjust their rotational speeds, enabling simultaneous feather removal and forward movement of the poultry.

During operation, the set of rollers near the discharge outlet is positioned upward to prevent poultry from moving forward prematurely. After the feathers are completely removed, the operator steps on a pedal to lower the rollers, releasing the defeathered poultry. Therefore, the machine works in batches; the number of birds processed per batch depends on the poultry type.

V. Installation & Commissioning

1. General Installation Procedure

1. Place the scalding and plucking machine in the designated position according to the drawings and the customer’s site conditions.
2. Level the machine and adjust the anchor bolts so that all supports bear load evenly and the machine is stable.
3. Connect the water supply pipe to the customer’s water mains.
4. Connect the steam inlet pipe to the customer’s steam network (for steam heating users only).
5. Install the electrical control box in a convenient, safe, and standard-compliant location.
6. Check the electrical components inside the control box for damage; verify that the motor power matches the control circuit.
7. A certified electrician should connect the main power and check the circuit according to the wiring diagram; verify that the motor rotation direction matches the indicated direction.
8. Check the water and steam pipes for leaks; repair any leaks or poor sealing immediately.

2. Service

Installation, commissioning, and after‑sales service can be carried out either by our company’s professional technicians or by the user under remote guidance from our customer service.

VI. Safe Use & Precautions

1. Before Use

• Read the instruction manual carefully before use to understand the basic structure and working principle.
• Before each shift, fill the scalding tank with an appropriate amount of clean water and heat it to the set temperature.
• Start the motor and other drive units before poultry enters the machine; allow them to run idle for at least 1 minute.

2. Operational Safety

• Do not touch the machine while it is running.
• Do not insert hands or any objects into the machine during operation.
• Do not touch cables, wires, heating tubes, or other live or high‑temperature parts.
• Only trained personnel are allowed to adjust or operate the machine.
• If there is no automatic water level controller, water must be added manually. A dedicated person must be in charge of the machine; multi‑person operation is prohibited.
