As we mentioned earlier, the steaming bags of chain convenience stores are currently frozen steaming bags produced by the standard chemical plant. The frozen steaming bags can be divided into: all machine steaming bags: all machine operated bags; Semi machine steaming: part of the operation is machine operation and part is manual operation (for example, all fillings are machine operation, and the packing is made manually).

手工蒸包：标准化工厂，纯手工制作三种形式中，最好吃的毕然是第三种，但成本自然也是最高的。根据冷冻的操作工艺，蒸包在便利店操作的时候分为两种情况，一种是冷冻蒸包直接蒸制的方法；一种是先把冷冻蒸包冷藏解冻后蒸制的方法。第二种方法较第一种方法更能保存产品的品质与味道，所以我们这里重点介绍第二种方法。

Manual steamed bread: in the standard chemical plant, among the three forms of pure manual production, the best food is the third, but the cost is naturally the highest. According to the freezing operation process, there are two situations when steaming bags are operated in convenience stores. One is the direct steaming method of frozen steaming bags; One method is to refrigerate and thaw the frozen steamed bag before steaming. The second method can preserve the quality and taste of the product better than the first method, so we focus on the second method here.

特别注意：蒸包机每天晚上要放水清洁，否则很容易酸锅；每半个月要除一次水垢。

Special attention: the steamer should be cleaned with water every night, otherwise it is easy to sour the pot; Scale should be removed every half a month.

PS：冷冻蒸包当前随着便利店的大规模扩张，发达地区的个体便利店完全可以找到代理商操作了，大家在选择冷冻蒸包时特别要注意的就是，要选择有正规SC的厂家。同时，代理商一定是有冷冻产品配送的资质。最后，你也要准备好冷冻设备进行储存。这些都是非常重要的！

PS: at present, with the large-scale expansion of convenience stores, individual convenience stores in developed areas can find agents to operate. When choosing frozen steamed bags, we should pay special attention to the manufacturers with formal SC. At the same time, the agent must be qualified for the distribution of frozen products. Finally, you should also prepare refrigeration equipment for storage. These are very important!
