core tip: vacuum packaging machine mainly refers to the ability to automatically extract the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum. Mechanical equipment that can also be filled with nitrogen or other mixed gases and then complete the sealing process. Vacuum packaging machines are often used in the food industry. The packaged products can prevent oxidation, mildew, moth eaten and moisture, and can guarantee quality, keep fresh and extend the storage life of products

[China Packaging News] vacuum packaging machine mainly refers to the ability to automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum. Mechanical equipment that can also be filled with nitrogen or other mixed gases and then complete the sealing process. Vacuum packaging machines are often used in the food industry. The packaged products can prevent oxidation, mildew, moth eaten and moisture, and can guarantee quality, keep fresh and extend the storage life of products

the development trend has been rising steadily. At present, the common vacuum packaging machine in the market is a semi-automatic vacuum equipment, which can automatically complete the whole process of vacuum, sealing, printing, cooling and exhaust by pressing the vacuum cap. In order to establish a new system of packaging machinery with diversification, generalization and multi-function integration, we must first focus on solving the major problems of combination and electromechanical integration, which is undoubtedly an important development direction in the future

with the development and application of high-efficiency and multi-functional vacuum packaging machines and packaging materials with excellent barrier properties, as well as the combination of vacuum packaging with physical and chemical methods such as inflation, radiation, freezing, oxygen getter, ethylene absorbent, etc., better storage and fresh-keeping effects will be achieved

nowadays, the development of packaging machinery and equipment has moved towards a comprehensive upgrading stage. This stage has a distinctive feature, that is, a large number of modern electronic technologies, microelectronic technologies, high-precision technologies, edge technologies, etc. from civil or military industries are adopted, so as to effectively improve the reliability and safety of packaging machinery and equipment and their production lines

based on the actual needs of reasonably simplifying packaging and advantageous packaging process methods, vacuum packaging machinery manufacturing enterprises need to constantly explore and speed up their own technological innovation, especially in line with the synchronous development of modern automatic machine tools

at present, the development trend of international vacuum packaging technology and equipment is mainly reflected in four aspects, namely, production automation, the adoption of new technology, single machine multi-function and assembly production line. The following is a specific elaboration from these four aspects

1. Production automation: the automation of vacuum packaging machine not only improves the production efficiency, but also has the advantages of safety and health

typ-b series rotary vacuum chamber packaging machine produced by Japanese company is a multi station packaging machine with a high degree of automation. The machine has two turntables for filling and vacuum pumping, and the filling turntable has six stations to complete bag supply, feeding, liquid injection and pre sealing, and send the packages to the vacuum pumping turntable; The vacuum turntable has 12 stations to complete the processes of vacuum pumping, sealing and finished product output. The production efficiency can reach 40 bags/minute. It is mainly used for packaging soft canned food

2. Adopt new technology: in terms of packaging methods, a large number of inflatable packaging are used to replace vacuum packaging, and the research of inflatable components, packaging materials and inflatable packaging machines are closely combined; In terms of control technology, computer technology and microelectronics technology are more applied; In sealing, heat pipe and cold sealing technology are applied; The advanced device is directly installed on the vacuum packaging machine, such as the computer-controlled high-precision combined scale for coarse particles; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied. Luo Baihui, Secretary General of the International Association of mold, hardware and plastic industry suppliers, said that the increasingly widespread application of plastic vacuum packaging has promoted the development of plastic vacuum packaging, which is not what we want to see. The overseas mergers and acquisitions of Chinese chemical enterprises are also relatively speculative and put forward higher requirements. The adoption of all these new technologies will make the vacuum packaging machine more efficient and intelligent

3. Single machine multi-function: realize multi-function on single machine, which can easily expand the scope of use

the multi-function of single machine is completed by modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different packaging materials, packaging ports and packaging requirements are produced

representative products include the multi station bag making vacuum packaging machine produced by Hesser factory affiliated to Bosch Company in Germany, which can integrate bag making, weighing, filling, vacuum pumping, sealing and other functions, which is convenient and fast

4. Assembly and distribution production line: when more and more functions are required, concentrating all functions on a single machine will make the structure very complex and inconvenient for operation and maintenance. At this time, several machines with different functions and matching efficiency can be successfully combined into a more complete production line to complete more complex packaging processes

the vacuum packaging production line for fresh fish developed by French cracecryoya and ISTM, and the textile vacuum packaging system developed by Swedish Shuhong International Co., Ltd. and Swedish Textile Research Institute belong to this type
