International vacuum packaging technology and equipment development trend

At present, the development trend of international vacuum packaging technology and equipment is mainly reflected in the following aspects.

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

The typ-b series rotary vacuum chamber packaging machine produced by the Japanese company is a multi-station packaging machine with a high degree of automation. The machine has two turntables for filling and vacuuming, and there are 6 stations for filling the turntable. The bag is filled, the material is fed, the liquid is pre-sealed, and the package is sent to the vacuum rotary table. The vacuum rotary table has 12 stations (vacuum Room), the process of vacuuming and sealing, finished product output, etc., the production efficiency can reach 40 bags / min, mainly used for packaging soft canned foods.

2, the use of new technology: in the packaging method, a large number of inflatable packaging to replace the vacuum packaging, the combination of inflatable components, packaging materials and inflatable packaging machine research; in the control technology, more application of computer technology and micro Electronic technology; in the aspect of sealing, application of heat pipe and cold sealing technology; installation of advanced equipment directly on vacuum packaging machine, such as computer-controlled coarse-grain high-precision combination scale; on rotating or vacuum packaging machine, applying advanced high-speed Circular surface cam indexing machine. Luo Baihui, secretary general of the International Association of Mould & Hardware Plastics Industry Suppliers, said that the application of plastic vacuum packaging has become more and more widespread, which has promoted the development of plastic vacuum packaging machines and put forward higher requirements. The adoption of all these new technologies will make vacuum Packaging machines are more efficient and intelligent.

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

The versatility of the stand-alone unit is done in a modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different packaging materials, packaging mouths and packaging requirements are produced.

The representative products are multi-station bag vacuum packaging machine produced by Hesser Factory of Bosch Company of Germany. It can integrate bag, weigh, fill, vacuum, seal and other functions in one, convenient and fast.

4. Assembling the production line: When more and more functions are needed, concentrating all the functions on one single machine will make the structure very complicated and the operation and maintenance will be inconvenient. At this time, several machines with different functions and matching efficiency can be combined into a more complete production line to complete more complicated packaging processes.

The fresh fish vacuum packaging production line developed by France's cracecryoya and ism company, the textile vacuum packaging system developed by Swedish Tree Hong International Co., Ltd. and the Swedish Textile Research Institute belong to this type.
