core tip: in recent years, food hygiene conditions that do not meet the standards have been constantly exposed by the media, and food safety problems have become increasingly serious and have endangered human health. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, the achievement of vacuum packaging has its own intellectual property rights. This new technology of packaging was born, and it was quickly distributed. Weiner and other senior executives of ISRI attended the forum

[China Packaging News] in recent years, the substandard food hygiene has been constantly exposed by the media, and the problem of food safety has become increasingly serious and has endangered human health. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, vacuum packaging, a new technology, has emerged and developed rapidly. With the development of economy and the leap of industrial level, the market has higher and higher requirements for packaging. Vacuum packaging machines are playing an increasingly important role in the field of circulation. At present, the competition of packaging machinery is becoming increasingly fierce. In the future, packaging machinery will cooperate with the trend of industrial automation, promote the overall level of packaging equipment, and develop multi-function, high efficiency and low consumption

the best feeling of desktop vacuum packaging machine empty packaging technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used in vacuum packaging. Since then, vacuum packaging has developed rapidly

China's vacuum packaging technology was developed in the early 1980s, while vacuum inflatable packaging technology began to be used in a small amount in the early 1990s. With the promotion of small packaging and the development of supermarkets, its scope of application is becoming more and more extensive, and some will gradually replace hard packaging, and the prospect is very promising

the vacuum packaging machine loads the food into the packaging bag, extracts the air in the packaging bag to reach the predetermined vacuum, then fills in nitrogen or other mixed gases, and then completes the sealing process

the characteristics of vacuum packaging are as follows:

1. The lower worktable adopts imported stainless steel plane structure, which can not only easily clear the liquid or sundries dripping on the worktable during the working process, but also prevent corrosion and rust caused by packaging acid, alkali, salt and other items

2. The upper working room is made of imported stainless steel, with large volume, light weight, high strength and corrosion resistance. All heating elements are installed in the upper working room, which can avoid short circuit and other faults caused by the influence of packaging items (especially liquids), and improve the reliability of the whole machine

3. Among them, dz-500/2s, dz-600/2s, dz-400/2s, dz-600/2s and dz-800/2s all adopt four-bar structure. There is an upper working room that works in turns to carry out the work of two stations, which is convenient to operate, efficient and energy-saving

4. The packaging process of several models is automatically controlled by the electrical system. For different packaging requirements and different packaging materials, this machine is equipped with self selected adjustment buttons such as air extraction time, heating time, heating temperature, etc., which are convenient for adjustment and can achieve the best packaging effect.

in the food industry, vacuum packaging is widely used, and various cooked products such as chicken legs, ham, sausage, etc; Vacuum packaging is increasingly used in pickled products, such as all kinds of pickles, bean products, preserved fruits and other foods that need preservation. After vacuum packaging, according to relevant experts from the Zihuan branch of the China Institute of standardization, the multi axis extrusion experimental machine in China's high-efficiency Electromechanical market only accounts for 10% ⑴ 5% of the total market, and 90% of these high-efficiency electromechanical products are used for export, which has a long shelf life and greatly extends the shelf life of food
