Development of beverage cans with automatic cooling/heating function

on the premise of continuously reducing energy consumption and pollution, iron printing cans are developing in the direction of high-grade, multi variety and deep processing to adapt to the international trend, such as the wide use of thin high-strength plates and chromium plated plates; Develop various interior coatings with different characteristics; Develop bottle cap products with various forms, easy to open, anti-counterfeiting and anti-theft functions, etc. Therefore, many new types of packaging have come out one after another

cold, refreshing or hot drinks can be drunk at any time and anywhere, which is not only the drinking method that consumers have always wanted, but also the opportunity to create business opportunities by developing this kind of beverage cans with automatic cooling/heating function

foreign self cooling cans

in the early 19th century, many people began to study self cooling cans. Although some packaging materials that claim to have self cooling function have been patented, these technologies and patents not only do not really solve the problem of effective self cooling of beverage cans, but also do not solve the environmental protection problems such as recyclable reuse and non pollution of the environment. At the same time, many problems in quality, safety, reliability and other aspects have not been solved. Therefore, we haven't seen a self cooling tank technology that can be industrialized so that people can really start using it and enjoy it anytime, anywhere

as early as last year, American self cooling tank Co., Ltd. (ccnv for short) announced that the era of truly starting to use self cooling tanks has arrived. This is not only a good news for consumers, but also a good opportunity for beverage manufacturers and packaging manufacturers to carry out product upgrading and technological upgrading, so as to expand product market sales. After nearly 9 years of research and investment of tens of millions of dollars, ccnv has finally developed and produced the world's first patented beverage can that truly realizes automatic refrigeration. When using self cooling cans, first of all, we introduce its hydraulic system, which is very convenient. As long as you press the plastic button at the bottom of the beverage can, the temperature of the beverage can can be reduced by 15 ℃ ~ 20 ℃ in 3 ~ 5 minutes

working principle of self cooling tank

self cooling tank mainly uses a patented technology of heat exchange system (HEU) to achieve the function of automatic cooling of beverage tank. HEU includes many components, such as beverage tank body, built-in HEU container, activated carbon, CO2 gas, etc. The working principle of HEU is very complex. HEU should keep the activated carbon adsorbing CO2 stable, and when the internal pressure of HEU drops, CO2 can be effectively released and achieve the function of heat absorption. Ccnv not only solves the problem that HEU is effectively used as a heat conversion device, but also enables HEU to be built into beverage cans. At the same time, it also solves the problem of energy conversion between two cans. The different air pressures it uses can ensure the safety of operators; The CO2 filling and release technology, as well as the elimination of the melting and release pollution of raw materials that determine the different sensors used, have reached the world's innovative level. In order to keep the beverage cool and refreshing for a long time after the cooling function of the self cooling tank is started, they adopted a HEU continuous cooling technology, which can keep the beverage tank in a low temperature state for a period of time. This function of rapid cooling and continuous heat preservation is beyond the traditional refrigerator and other refrigeration technologies

In order to make the self cooling tank technology meet the requirements of industrialization such as mass production, ccnv also designed and invented the self cooling tank equipment production line and product quality inspection procedures and equipment, with a design capacity of 150 per minute. The first production demonstration line of self cooling cans has been built in New Jersey, USA. They are working hard to formulate international technical standards for self cooling tanks. The invention technology of self cooling cans will bring new ideas and revolution to the world beverage packaging. Therefore, the company's products were rated as the 1997 can making honorary products by the American canned magazine, listed as environmental protection products by the U.S. Environmental Protection Agency, and recognized and used by NASA and the U.S. Department of Defense

domestic self cooling (self heating) beverage cans

domestic self cooling cans have also achieved gratifying results. Shanghai East China food and beverage industry research institute has successfully developed a new generation of "self cooling (self heating) beverage cans", which has been rated as a recommended product by the Chinese Society for food science and technology

Professor Huasheng, deputy director of Shanghai East China food and Beverage Industry Research Institute, said that this self cooling tank is actually an integral dynamic structure made of the principle of cold and heat absorption reaction. Through the knob switch outside the tank, it makes the liquid reagent react quickly with the refrigerant in the tank, so that the cooling or heating phenomenon occurs quickly in the outer cup, and then the temperature is transmitted to the beverage in the inner cup, so that the beverage can be reduced by 10 ℃ ~ 15 ℃ or heated to 43 ℃ ~ 50 ℃ within 1 ~ 2 minutes. In this way, consumers can drink the drinks they need in a short time. The edible part of this self cooling can product is packed with polypropylene plastic cups for food, ordinary polypropylene plastic cups for the outer layer, refrigeration materials in the interlayer, and corrugated boxes for finished drinks

after the launch of preliminary products, the "self cooling easy pull drink cans" are popular with the majority of consumers. Therefore, on the basis of the first generation products, the "self heating easy pull cans" and the second and third generation products of the "self cooling easy pull cans" will be launched one after another

according to experts' estimates, the cost of producing a bottle of this self cooling can beverage is 1.3 ~ 1.65 yuan, and the market price is 3 ~ 6 yuan. Of course, if the enterprise has a large output, the cost will be reduced, which is equivalent to the current beverage price, with a small price difference, which is easy for consumers to accept

market development of new cans

self cooling cans are a new product, which will create a new market for enterprises after development and promotion. In terms of the consumption of cans in China, the per capita consumption of cans in China is only 4.6 cans, which cannot be compared with 380 cans per capita in the United States, and the market potential is huge. In particular, China is a developing country. The popularity of refrigerators is not too high, the use of refrigerators is not wide enough, and the population mobility is large. The concept of getting cold drinks anytime and anywhere is very suitable for China. Self cooling cans can also reduce the investment cost of service facilities such as vending machines and hotels. At present, Heineken Heineken beer will become the first user of self cooling cans in Europe. It will purchase 85% of the output of self cooling cans in the first year of ccnv and take the lead in using self cooling cans on European beer packaging. Coca Cola, Pepsi and other beverage giants have also conducted cooperation negotiations with ccnv on the use and investment of self cooling can technology

in addition, Nestle UK has recently launched the 330ml new concept "automatically heated milk coffee can". Its principle is to place water and quicklime in the interlayer of the tank respectively and generate heat through chemical reaction. Therefore, the volume of the tank is reduced, and it can hold 210 ml of liquid drinks

when the finished product tank arrived at Nestle factory, the tank was not filled with chemical reactants. After the milk and coffee drinks are loaded into cans in the traditional way, the semi-finished products are transported to the nearby thermal energy processing plant for a series of complex loading work, and then the cans are sealed, labeled and boxed. This process includes quantitative filling of thermal reactants and sealing to ensure that quicklime water will not leak

for the convenience of consumers, a round pull ring is designed on the top of the jar. The heating process is controlled by the button at the bottom. About 3 minutes, the beverage can reach 60 ℃. In order to prevent consumers from being scalded by hot drinks. 9. After the experiment, press the power switch to close the wound. The outer layer of the can has a corrugated isolation layer and a specially designed shrink sleeve. The shrink sleeve has high transparency and is printed with 9-color photographic plate, which is very beautiful

in addition, self heating sake cans have emerged in Japan. There is an interlayer at the lower 1/5 of the tank, which contains quicklime and a small packet of water in the sealed plastic film. Before drinking, as long as a "attached" plastic stick is inserted from the hole in the lower part, the water will immediately be mixed with quicklime to generate a lot of heat. It only takes 3 minutes to heat a can of sake to 58 ℃

nearly 1trillion liters of beverages are produced every year in the world. These beverages use different packaging materials, such as glass, plastic, paper products, metal, etc. In the use of metal cans, 25% - 30% are sold through convenient small supermarkets and automatic cold drink vending machines, which is equivalent to nearly 60billion cans. At present, it is increasing at an annual rate of 5%. It can be seen that people are widely interested in the use of convenient metal cans. Self cooled cans can not only meet people's growing demand for convenient beverage packaging, but also have a value-added function, so its market prospect has great temptation. In the case of fierce market competition, whoever first owns the products with updated technology in all aspects of cans can occupy a certain opportunity in the cans Market and occupy a certain dominant position in the increasingly fierce market competition
