The poultry dip-and-scald tank is a critical piece of equipment used in the scalding process during poultry slaughter and processing. The following provides a detailed introduction from five aspects: equipment features, working principle, technical parameters, application scenarios, and purchasing recommendations.

### **I. Equipment Features**

1. **Durable material**

The main body is made of either stainless steel or carbon steel. Stainless steel has strong corrosion resistance and is suitable for long-term exposure to humid environments; carbon steel, while lower in cost, requires regular anti-corrosion treatment. Some high-end models use plates that are 5mm to 8mm thick to ensure the equipment’s stability.

2. **Precise temperature control**

Equipped with an automatic temperature-control system, the water temperature can be set between 60-68℃ (adjusted according to the poultry breed), preventing both “undercooked” and “overcooked” conditions and ensuring that feathers come off easily while maintaining a bright, vibrant color in the carcass.

3. **Stir well**

The motor drives a rubber roller or stirring device to flip the poultry during the scalding process, ensuring even heating and improving depilation efficiency. Some equipment employs a combination of airflow and mechanical stirring to further optimize performance.

4. **High degree of automation**

The integrated automatic conveying function allows cooked poultry to be transferred to the plucking machine via a chain or water-propulsion device, reducing the manual retrieval step and saving labor.

5. **Energy-saving and environmentally friendly**

It adopts a closed-box structure to reduce steam heat loss. Some models support steam heating, electric heating, or thermal oil heating; users can choose based on their energy availability.

### **II. Working Principle**

1. **Scalding After Bleeding**: After poultry is slaughtered and bled, it is manually or mechanically conveyed into a scalding tank.

2. **Constant-Temperature Stirring**: The water temperature is kept constant within the set range, and the stirring device ensures that the poultry are turned over, guaranteeing thorough heating of the feather roots.

3. **Automatic Conveying**: After scalding is complete, the poultry is conveyed via a conveyor system into the plucking machine to complete the plucking process.

### **III. Technical Parameters (Taking Common Models as Examples)**

| **Parameter** | **Value Range** |

|------------------|---------------------------|

| Power supply voltage | 380V |

| Power | 2200W–18000W (depending on model) |

| Work Capacity | 400-2000 units/hour |

| External dimensions | 3900×2100×1200mm (large) |

| Weight | 1500Kg |

| Heating Method | Electric Heating / Steam Heating / Thermal Oil Heating |

| Sheet thickness | 3mm (stainless steel) / 5mm (carbon steel) |

### **IV. Application Scenarios**

1. **Large-Scale Slaughterhouse**: Choose a model with strong processing capacity (e.g., 1,500–2,000 birds per hour) and pair it with a horizontal depilating machine to enable assembly-line operations.

2. **Medium-sized slaughterhouse operators**: Choose medium-sized equipment (capacity of 600–800 animals per hour) to balance efficiency and cost.

3. **Small-scale farm**: A small scalding tank (capacity of 400–500 birds per hour) is available for self-use needs.

### **V. Shopping Recommendations**

1. **Material Selection**:

- For humid environments or long-term use: Stainless steel is the preferred material.

- Limited budget and short-term use: Carbon steel material could be considered, but regular maintenance is required.

2. **Heating Method**:

- Sufficient steam supply: Choosing steam heating offers high efficiency and low costs.

- No steam source required: Electric heating or thermal oil heating can be selected, offering high flexibility.

3. **Capacity Matching**:

- Select the equipment model based on the daily slaughter volume to avoid overcapacity or insufficient capacity. For example, if the daily slaughter volume is 5,000, you should choose equipment with a hourly output of more than 1,000 birds.

4. **Brand and Services**:

- Prioritize brands that offer lifetime after-sales service to ensure the equipment operates reliably over the long term.

5. **Additional Features**:

- Need to save labor: Choose a model with automatic conveyor function.

- Precise temperature control required: Choose a temperature control system equipped with a digital display.

### **6. Market Reference Price**

。  

- **Medium-sized equipment**: 50,000–70,000 yuan (producing 800–1,500 units per hour).
