COVID-19 continues.
During the quarantine period, it was inconvenient to go out, which made instant food usher in a sales peak, especially self-heating food with self-heating function. The heating bag that comes with self-heating food is mainly composed of iron powder, aluminum powder, coke, activated carbon, quicklime, and other materials. Then through the continuous oxidation of iron powder, aluminum powder, etc., heat is released, to cook the food.
Now, the market for self-heating food is becoming more and more active, the competition is becoming more and more fierce, and the situation of survival of the fittest will inevitably appear. Quality is the strong competitiveness of production enterprises, which also means that in the future, self-heating food production enterprises have higher requirements for vacuum packaging equipment. Packaging equipment manufacturers need to improve the technical content of equipment, promote the development of new products, and win more customers. of attention.
To ensure the quality of food and prolong the shelf life of ingredients, food packages in self-heating food are usually packaged with vacuum packaging equipment. The technology and performance of vacuum packaging equipment are continuously improved to promote the quality of self-heating food.
Vacuum packaging technology is widely used in food work, and the market size of equipment is very considerable. The vacuum packaging machine can automatically extract the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum degree. Vacuum packaging machines are divided into internal vacuum packaging machines and external vacuum packaging machines, as well as the often-mentioned automatic vacuum packaging machines. The internal vacuum packaging machine is divided into a single-chamber vacuum packaging machine, a double-chamber vacuum packaging machine, a vertical vacuum packaging machine, and a continuous rolling vacuum packaging machine. At present, the most commonly used vacuum packaging machines on the market are stretch film vacuum packaging machines, continuous vacuum packaging machines, and bag-feeding automatic vacuum packaging machines.
Customers can choose according to their product properties: small bag packaging and solid products can use an internal vacuum packaging machine; large bag packaging should choose an external vacuum packaging machine; powder or granular products should choose a vertical packaging machine; products with moisture content To choose a concave vacuum packaging machine.
For the manufacturers of vacuum packaging machines, it is also for us to speed up the development and application of new technologies and new materials, manufacture high-precision and large-scale vacuum packaging equipment, improve packaging quality, and speed up packaging. Secondly, we must also strengthen the safety, sanitation, and energy-saving level of equipment, to achieve green production.
At present, the development trend of international vacuum packaging technology and equipment is mainly reflected in four aspects, that is, the trend of intelligence, the adoption of new technologies, and single-machine multi-function and assembled production lines.
1.Tend to be intelligent. In the case of not achieving the intelligence of the packaging production process, improving the automation of production equipment not only improves production efficiency but also has the advantages of safety and hygiene.
2. Adopt new technology. In terms of packaging methods, a large number of air-filled packaging is used to replace vacuum packaging, and the research on air-filled components, packaging materials, and air-filled packaging machines is closely combined; in the controller, more computer technology and microelectronic technology are used; Heat pipe and cold sealing technology; install advanced devices directly on the vacuum packaging machine, such as a combination scale for counting particles.
3. Single multi-function. To achieve multi-function on a single machine, it is convenient to expand the scope of use and to switch different modules to produce a vacuum packaging machine suitable for different packaging materials and packaging requirements.
4. Assemble the production line. When more and more functions are required, several machines with different functions and matching efficiency should be combined into a fully-engineered production line to complete more complex packaging processes.
