The world's most advanced two-piece can aseptic filling
at present, the world's most advanced full-scale two-piece can aseptic filling production line has been successfully developed in Europe. Set the size of this operation: the width is (15 ± 0.1) mm, and the developed length is (100 ± 1) mm. The line is from refreshco holding
the collaborator of this research and design project is a global company composed of Ball Packaging Europe and refreshco. The latest products produced by this production line were listed at the end of 2005.
because of the heat sensitivity of food raw materials, that is, the poor heat resistance, some foods that cannot be produced by traditional canning methods can be produced by using this patented new processing technology and a new sterile filling line. High temperature and oxygen are important factors that affect the taste, color and nutritional value of finished food. It's best not to rush to buy. Now, the ABC operation line successfully designed by the new research can ensure that the shelf life of the products produced can reach the required 12 months at room temperature, and that the products will not have any corruption and deterioration caused by microorganisms during this shelf life, so as to slim down and keep fit. In 1999, ball packagingeurope, Mennen Ding food and Serac cooperated to study this project. In the same year, the research and design of this aseptic filling production line for beverage cans with an annual production capacity of 5million cans were completed. This new research successfully proves the following facts: even if the high requirements of high-quality product production cannot be met, the aseptic filling of full-thickness cans can be carried out. This ABC operation has been successfully used in the commercial production of milk drinks and other products in CAMPINA internationae company. The filling speed is 100 cans per minute, and 20million cans have been filled so far. The so-called aseptic filling refers to the whole process of filling sterilized beverages into pre sterilized containers under aseptic environmental conditions, and then sealing the packaging containers in the clean room (ultra clean workshop). Therefore, the following bottleneck (difficult) problems can be predicted immediately. During and after filling, the product is stored without heating and sterilization. Moreover, the products must be free of spoilage bacteria and cold storage. Therefore, under such manufacturing environmental conditions, the control and appropriate health management in the processing process are very important. The ultra clean workshop with filling and container sealing environment must also maintain absolute hygiene. One of the necessary conditions is the high experimental technical state. Aseptic filling is quite different from the traditional high temperature and high pressure sterilization method. Now, the polyester bottle production line set up by French refreshco company has used this sterile filling system. The core part of ABC flow line is the filling system of Serac company. The metal can is composed of a can body and a can cover. The tank body needs to be sterilized by 210% dry heat after washing. Since the silicone coating of the three piece can is not resistant to high temperature treatment, it cannot be treated at this temperature. For this reason, another method, high-frequency induction heating method, was used to sterilize cans at 160 ℃.
the can body is filled with beverages pre sterilized by ultra high temperature (UHT) sterilization in the ultra clean workshop. Then immediately inject sterile liquid nitrogen into the top gap of the can. As soon as the liquid nitrogen drops, it immediately changes into nitrogen and occupies the entire top gap, in order to isolate the pollution and invasion of oxygen and fungi. Then use the can roll sealing machine to seal. Usually, this sealing opportunity is used to form too much air flow, which is easy to cause the risk of secondary pollution. Now they have developed a new sealing machine. However, after filling and filling with liquid nitrogen, the curling and sealing process can be carried out immediately, which can reduce the risk of this secondary pollution to zero. Liquid nitrogen filling the top gap has three functions. Prevent pollution, remove oxygen from the top gap, and form an internal pressure to give the can a certain rigidity; Compared with PET bottles, metal cans are impervious to oxygen and light, so the shelf life of products can be extended for at least 1 year, during which the change of product sensory quality can be prevented; As compared with paper containers, cans are stronger and more suitable for the vending machine sales industry, and recycling is also very convenient. Metal cans are these characteristics and very attractive to consumers. Although the cost of ABC flow production line is the same as that of high temperature and high pressure sterilization canning line and sterile PET bottle operation line, the cost of canning itself is lower than that of heat-resistant PET bottles.
this drink has a very good market popularity in the United States because it gives people a healthy image; It is still in the immature market development period in Europe; The latest refrigerated coffee cans have appeared in Germany and southern Europe; Japan has a large market of more than 8.6 billion cans every year
