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.

敞開式較簡單，它由循環(huán)泵、水槽、管道及控制閥門的調(diào)節(jié)器所組成，當(dāng)采用高壓水時，設(shè)備機械強度要求高，反應(yīng)釜外表面焊上管與釜壁有間隙，使熱阻增加，傳熱效果降低。

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壓的加熱系統(tǒng)時，可用其它介質(zhì)來代替水和蒸汽，如礦物油、聯(lián)苯醚混合劑（沸點、熔鹽、液態(tài)鉛等。因此，在電阻絲與反應(yīng)釜體之間形成了不大的空間間隙。前三種方法獲得高溫均需在釜體上增設(shè)夾套，由于溫度變化的幅度大，使釜的夾套及殼體承受溫度變化而產(chǎn)生溫差壓力。

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.

采用電加熱時，設(shè)備較輕便簡單，溫度較易調(diào)節(jié)，而且不用泵、爐子、煙囪等設(shè)施，開動也非常簡單，危險性不高，成本費用較低，但操作費用較其它加熱方法高，熱效率在以下，因此適用于加熱溫度在以下和電能較低的地方。

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.

在不銹鋼白酒罐的加熱系統(tǒng)中通常要進行化學(xué)反應(yīng)，為保證反應(yīng)能均勻而較快的進行，提率，通常在反應(yīng)釜中裝有相應(yīng)的攪拌裝置，于是便帶來傳動軸的動密封及防止泄漏的問題。

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.
