The chemical reaction of stainless steel Baijiu tank usually needs to be carried out under certain temperature conditions, so the reaction kettle bears both pressure and temperature. There are usually several ways to obtain high temperatures: steam heating can be done by heating with steam at a temperature below atmospheric pressure; Use saturated steam within the range; When the temperature is higher, high-pressure superheated steam can be used. When water heating requires a low temperature, it can be used. There are two types of heating systems: open and closed.

敞开式较简单，它由循环泵、水槽、管道及控制阀门的调节器所组成，当采用高压水时，设备机械强度要求高，反应釜外表面焊上管与釜壁有间隙，使热阻增加，传热效果降低。

The open type is relatively simple, consisting of a circulating pump, water tank, pipeline, and a regulator that controls the valve. When high-pressure water is used, the mechanical strength of the equipment is required to be high. There is a gap between the welded pipe on the outer surface of the reaction kettle and the kettle wall, which increases the thermal resistance and reduces the heat transfer effect.

其次，操作或欲避免采用高压的加热系统时，可用其它介质来代替水和蒸汽，如矿物油、联苯醚混合剂（沸点、熔盐、液态铅等。因此，在电阻丝与反应釜体之间形成了不大的空间间隙。前三种方法获得高温均需在釜体上增设夹套，由于温度变化的幅度大，使釜的夹套及壳体承受温度变化而产生温差压力。

Secondly, when operating or avoiding high-pressure heating systems, other media such as mineral oil and steam can be used instead The mixture of diphenyl ether (boiling point, molten salt, liquid lead, etc.) forms a small spatial gap between the resistance wire and the reactor body. The first three methods of obtaining high temperature require adding a jacket on the reactor body. Due to the large amplitude of temperature change, the jacket and shell of the reactor are subjected to temperature changes and generate temperature difference pressure.

采用电加热时，设备较轻便简单，温度较易调节，而且不用泵、炉子、烟囱等设施，开动也非常简单，危险性不高，成本费用较低，但操作费用较其它加热方法高，热效率在以下，因此适用于加热温度在以下和电能较低的地方。

When using electric heating, the equipment is relatively light and simple, the temperature is easy to adjust, and facilities such as pumps, furnaces, and chimneys are not needed. It is also very simple to start, with low risk and cost. However, the operating cost is higher than other heating methods, and the thermal efficiency is below. Therefore, it is suitable for places where the heating temperature is below and the electricity price is lower.

在不锈钢白酒罐的加热系统中通常要进行化学反应，为保证反应能均匀而较快的进行，提率，通常在反应釜中装有相应的搅拌装置，于是便带来传动轴的动密封及防止泄漏的问题。

Chemical reaction is usually required in the heating system of stainless steel Baijiu tanks. In order to ensure that the reaction can be carried out evenly and quickly and improve efficiency, the reaction kettle is usually equipped with a corresponding mixing device, which brings about the problem of dynamic sealing of the drive shaft and preventing leakage.
