The Beijing Roasted Duck Scalding Machine is a specialized piece of equipment used for scalding the duck carcass during the preparation of Beijing roasted duck. Below is a detailed introduction to the Beijing Roasted Duck Scalding Machine:

### I. Working Principle

The scalding machine heats the duck body and sprays mist or hot water onto its surface, causing the pores to contract, the skin proteins to coagulate, and the gases beneath the skin to expand to their maximum extent. This results in a denser, tighter skin that helps speed up the drying of the duck carcass, gives it an attractive appearance, ensures even coloring during roasting, and produces a crispy, fragrant duck skin once cooked.

### 2. Operation Procedure

1. Cleaning the equipment: Before use, thoroughly clean the inside and surface of the scalding machine and wipe off any moisture.

2. Preparing the duck: Hang the ducks that need scalding, ensuring they are in a suitable condition for scalding.

3. Start the equipment: Turn on the power or air source switch of the hot-fix machine to bring it to normal operating condition.

4. Adjust the temperature and water flow: Set the temperature and water flow rate of the scalding machine according to the desired degree of scalding. As a general guideline, the temperature should be between 92°C and 95°C, and the water flow rate should be moderate to ensure even heating of the ducks.

5. Scalding operation: Place the duck into the scalding machine, where the equipment will automatically spray mist or hot water onto the duck’s surface. Depending on the machine’s settings, the scalding time typically ranges from a few seconds to several tens of seconds.

6. Remove the duck: Once the scalding process is complete, remove the duck from the scalding machine and proceed to the next step.

### 3. Equipment Features

1. High degree of automation: Modern embossing machines typically employ automated control systems that can automatically perform the embossing process, significantly boosting production efficiency.

2. Even heating: The duckling heating machine employs advanced heating technology to ensure uniform heating of the ducks, preventing localized overheating or underheating.

3. Easy operation: The hot-embossing machine has a simple and easy-to-understand operating procedure; operators only need to follow the equipment instructions to use it.

4. Energy efficiency and environmental protection: Modern hot-embossing machines typically feature energy-efficient and environmentally friendly designs, which can reduce energy consumption and minimize pollution.

### IV. Precautions

1. Before use, carefully read the instruction manual to ensure proper operation of the device.

2. During use, do not put your hands inside the hot-molding machine to avoid accidents.

3. After use, the equipment should be cleaned promptly to keep it hygienic and free of bacteria.

4. During operation, if the temperature of the scalding machine is too high or the speed is too fast, adjust it promptly to avoid damaging the ducks.

In summary, the Beijing roast duck scalding machine is an indispensable piece of equipment in the preparation of Beijing roast duck. By using and maintaining the equipment properly, we can ensure that the quality and taste of Beijing roast duck reach their optimal level.
