‌滚揉机的工作原理‌主要是利用物理冲击的原理，使肉在滚筒内上下翻动、相互撞击、摔打，从而达到按摩和腌渍的作用。滚揉机通常在真空状态下工作，通过真空泵将滚揉桶内的空气抽出，形成一定的真空环境。这种真空状态有助于肉品中的水分和腌渍液更好地渗透和分布，同时减少氧气的存在，有助于保持肉品的色泽和防止氧化。‌

滚揉机的具体操作过程‌包括以下几个步骤：

‌加料‌：开启真空泵，在达到一定的负压时，将吸料管连接上吸料。

‌抽真空‌：使用真空泵抽真空并保持真空度。

‌设置运行时间‌：滚揉机有专门的时间设置按钮，可以根据不同的需要来进行设置，时间从秒到小时不同设置。

‌间歇滚揉‌：滚揉机生产时会有一定的间歇，可以根据不同需要来自定义设置间歇时间和工作时间，拥有独立的时间控制按钮。

‌运行‌：将控制面板上的旋钮扳到“运行”，真空泵和充气旋钮扳到“开”，机器开始按设定方式运行。

‌结束与出料‌：当滚揉时间达到设定值时，滚揉机会自动停止工作。此时，可以等待滚揉桶内外的压力平衡后放出料，然后进行清洗和消毒处理。

‌滚揉机的应用领域‌主要包括食品加工行业，特别是在肉食制品和低温火腿的生产中。通过滚揉、按压和腌制的过程，真空滚揉机能够将嫩化后的原料肉与辅料、添加剂等在真空状态下均匀拌合，使蛋白质与盐水充分接触，增加肉块之间的粘合力，提高肉类的嫩度和水性，从而改善肉块品质。

The working principle of a rolling and kneading machine is mainly based on the principle of physical impact, which causes the meat to flip up and down, collide with each other, and fall inside the drum, thus achieving the functions of massage and pickling. Rolling machines usually work in a vacuum state, and the air inside the rolling drum is extracted by a vacuum pump to create a certain vacuum environment. This vacuum state helps to better penetrate and distribute moisture and marinade in meat products, while reducing the presence of oxygen, which helps maintain the color of the meat and prevent oxidation. ‌

The specific operation process of the rolling mill includes the following steps:

Feeding: Turn on the vacuum pump and connect the suction tube to the suction tube when a certain negative pressure is reached.

Vacuum pumping: Use a vacuum pump to evacuate and maintain the vacuum level.

Set running time: The rolling machine has a dedicated time setting button that can be set according to different needs, with different time settings ranging from seconds to hours.

Intermittent rolling: The rolling machine has a certain interval during production, and the interval time and working time can be customized according to different needs, with independent time control buttons.

Run: Turn the knob on the control panel to "Run", turn the vacuum pump and inflation knob to "On", and the machine will start running according to the set mode.

End and discharge: When the rolling time reaches the set value, the rolling machine will automatically stop working. At this point, the material can be released after the pressure inside and outside the rolling drum is balanced, and then cleaned and disinfected.

The application areas of rolling machines mainly include the food processing industry, especially in the production of meat products and low-temperature ham. Through the process of rolling, pressing, and marinating, the vacuum rolling machine can evenly mix the tender raw meat with auxiliary materials, additives, etc. in a vacuum state, allowing the protein to fully contact the salt water, increasing the adhesion between the meat pieces, improving the tenderness and water properties of the meat, and thus improving the quality of the meat pieces.
