In March 2016, "convenient hot pot" appeared in the market as the prototype of convenient hot pot, and in December of the same year, the simple version of "convenient hot pot" began to become popular in micro-business channels. It was not until around March 2017 that the entry of professional hot pot brands such as Dalongyi, Xiaolongkan, and Dezhuang officially detonated the convenient hot pot market, and many brands intervened.
 
As one of the first professional hot pot brands to enter the convenient hot pot market, Dalongyi occupies a large share in the convenient hot pot market by virtue of its own popularity and deep consumption base, and is more guaranteed in taste than some non-professional brands. The instant hot pot produced by it is a peripheral product, similar to the hot pot base and dry dishes on sale, but the difference lies in the change of taste and side dishes. Compared with simple Malatang and Maocai takeaway, convenient hot pot can be heated and kept warm independently, but in essence, it is not much different from the taste and ingredients of products such as Malatang and Maocai. Although convenient hot pot is far from being comparable to traditional hot pot in terms of taste, the diversified scene extension does attract many loyal fans.
 
The soul of hot pot lies in the base, and convenient hot pot is no exception. In 2015, Da Long Yi began to sell hot pot base and chili dishes, which are provided by fixed manufacturers for a long time, and will also provide some ingredients to manufacturers according to the taste, such as Maowen peppercorns directly harvested from its raw material cultivation base in Maowen, Sichuan, which makes Dalongyi, as a catering brand, make up for its shortcomings in production capacity. Another protagonist of instant hot pot is the side dish, which has a shorter shelf life than other instant products due to problems such as dish preservation, storage, and transportation, usually between 6 months and 1 year. This makes the convenient hot pot limited in terms of dish matching, and Da Longyi has classic dishes such as potatoes, lotus root slices, fungus, and bamboo shoot slices on the dishes.
 
At this stage, Da Longyi's portable pot includes 5 flavors, namely Meat Duoduo, Beef Duoduo, Cai Duoduo, Stilt Beef and Tomato Brisket. Among them, the meat is the main model of Da Longyi, just like its name, the beef is large, the bottom of the butter pot is fragrant, and the spicy degree is moderate, and people who are not too spicy can also accept it. The sausage inside is the highlight, moderately sweet and salty, with a slight wine flavor, very chewy, which is a unique combination among all the convenient hot pots. Beef Duoduo is another more classic flavor in addition to Meat Duoduo, the bottom of the pot and the vegetarian vegetable package are the same as the meat Duoduo, the butter flavor is heavier, the spicinessness is similar, the meat dish is braised beef, how much more sausage buns than meat, and the taste is not as rich as meat. These two flavors also come with sesame oil and aged vinegar packets, which can be seasoned independently, which is a good choice.
 
Vegetable duoduo, stilted beef and tomato brisket are all in the bottom of the pan. Cai Duoduo is a vegetarian pot, the spiciness is similar to that of meat, and the vegetarian dishes are exactly the same, including potatoes, lotus root slices, kelp, fungus, bamboo shoot slices, the lotus root slices are crispy, and the vermicelli is flavorful, which performs well in the vegetarian pot, and vegetarian lovers can choose. Stilted beef and tomato brisket are not spicy flavors, lumpy beef and beef brisket are larger, the meat is with fascia, very chewy, but both are matched with fine powder, the heating time needs to be properly controlled, and it is easy to rot after cooking for a long time, which is not as chewy as the wide powder of several other flavors. These three are slightly inferior to the two flavors of Meat Duoduo and Beef Duoduo, and there are no sesame oil and aged vinegar packets.
 
The packaging material of Dalongyi portable pot is heat-resistant PP5 material, which is a food packaging plastic that meets safety specifications. At present, the plastic packaging used by regular manufacturers has passed the food safety packaging regulations, and no harmful substances will be produced during the heating process, so consumers can rest assured. The heating principle of instant hot pot is similar to that of instant rice, relying on quicklime to react with water to generate heat, and the key to its safety is actually the heating package and anti-scalding design. If the ventilation hole on the lid of the hot pot is blocked or the heating bag is broken, it may cause a small explosion or even burn people. Although the heating effect of the Dalongyi heating package is not outstanding, the sealing is not bad, the anti-scald design is average, and it is equipped with a universal thermal insulation gasket and anti-scald handle. The price of Dalongyi portable pot is basically the same as that of professional hot pot brands, with meat pot at about 37 yuan and vegetarian pot at about 27 yuan.
