Behind Haidilao's "hair belly shrinkage": the principle of reducing shrinkage in the hair making process will build smart catering to promote product standardization

China Net Finance news on October 24 (reporter Qiao Yi) many stores to cooperate with weighing, invite customers to visit the back kitchen, and promote the construction of smart catering... After the "hair belly shrinkage" incident in Haidilao's Zhengzhou store, stores around the country have taken multiple measures to ensure the production process.

Hair making process to restore "hair belly slimming"

On October 19, Haidilao was on Weibo hot search for "only 138g of hairy belly dishes marked as 200g", and then, Haidilao official micro apologized for the first time and made an explanation, saying that it was caused by employees' operation errors and putting the hairy belly plate into the freezer in advance and causing its water loss. Haidilao also said that it supports consumers to protect their rights according to law, and has taken the initiative to report to the market supervision department because it has not reached an agreement with consumers on the amount of compensation.

While this statement has been recognized by some consumers, some comments have expressed their confusion that "the water content of the hairy belly can be so large?" "It is recommended that Haidilao weigh publicly, intuitively and transparently."

It is understood that the city's wool belly is divided into fresh hair belly and dry hair belly, but no matter which one, it must be made before it can be eaten. According to industry insiders, if the fresh hair belly is directly into the pot and blanched, its taste is like chewing eraser, which is not only not conducive to digestion, but also difficult to swallow. "So 98%-99% of the hair belly sold on the market is dried hair belly, and the dry hair belly needs to be made before eating, taking the foaming process as an example, the weight of 5 different hair systems reaches 18% to 144%, which is a common phenomenon."

Talking about the loss of water in the hair belly, the industry insider explained that from a scientific point of view, in the process of low temperature preservation, the moisture of the food will continue to evaporate to the ambient air and gradually decrease, resulting in a reduction in weight. "This is a dry consumption process, when there is a vapor pressure difference between the surface of the food and the air around it, after the food absorbs the latent heat of evaporation or sublimation of latent heat, the water is evaporated or the ice crystals sublimate to form water vapor, and under the action of the pressure difference of water vapor, it is transferred to the air, and the air that absorbs the moisture rises due to the lighter density, and when it comes into contact with the evaporated gas, it is condensed into frost." After dehumidification, the air sinks due to the increase in density, and then comes into contact with food, repeating the above process. In this cycle, the moisture of the food will be continuously lost, and the weight will be reduced. ”

In response to the above problems, the financial reporter of China Net called Haidilao for verification. The relevant person in charge said that according to the post operation process, the hair belly needs to ensure that it is fresh and produced, and the storage time after plating should be within half an hour, but the dishes involved are actually prepared for the employees in advance, and they are placed in the freezer after being plated according to the portion, and the water loss occurs, resulting in inconsistencies with the number of grams produced.

"For the employee's operation mistake, Haidilao is deeply sorry." The person in charge told reporters that there is a strict post operation process within the company, and after the incident, it has carried out internal inspection for the first time, reviewed the post operation process, and urged employees to strictly comply with the operation specifications. "Next, Haidilao will take this incident as a warning, use the normalized supervision and feedback mechanism, strengthen the employees' awareness of standardized operation, and through internal training, improve the operation ability of employees to better meet customer needs."

Build smart catering to promote product standardization

In fact, in response to the standardization problem of the catering industry, Haidilao launched the construction of smart catering as early as 2018, exploring new technologies to change the cost structure of catering enterprises, using digital and intelligent means to improve customer experience, reduce costs and increase efficiency and ensure food safety. It is reported that at present, there are 6 stores in Beijing and 5 stores in Zhengzhou to promote the 5S visual management model.

"In the next step, we will continue to promote the construction of smart catering, explore the use of new technologies to promote product standardization, and reduce the risk of errors caused by manual operations to ensure product quality and improve food safety." According to the person in charge of the company, Haidilao will continue to take rectification measures in a timely manner and accept supervision from all walks of life by actively reporting the problems found in internal supervision and management on the basis of the bright cooking stove, at the same time, the stores in various regions will also promote the development of offline customer supervision activities according to the epidemic prevention deployment in their regions.

A search by a financial reporter from China Net found that at present, Haidilao has stores in Hunan, Shenyang, Jiangsu, Shandong and other places to invite customers to visit the haidilao kitchen. Taking the Weibo keyword "Haidilao Back Kitchen" as an example, many netizens have shared their experience of exploring the store on social platforms. In addition, there are also bloggers who take the scale to dine, and supervise and re-inspect the standard weight of the dishes on the spot.

In this regard, Haidilao said that the store will cooperate with consumers to complete the weighing of dishes and strictly demand themselves with supervision. "The company attaches great importance to the customer's consumer experience, thanks to the long-term attention and love of all sectors of society for Haidilao, help us find problems, put forward opinions, we will continue to improve, optimize, for the majority of customers to bring a better consumer experience."
