As an assembly team leader who has worked in our factory for eight years, the most common question asked by customers every day is: "Lao Wang, how much pressure should be adjusted for the vacuum generator of your packaging machine?" Today, I will talk to you about this tip from the bottom of my heart.
Speaking of the core component of the vacuum generator, it is the "heart and lung function" of the packaging machine. Last year, when we upgraded the production line for a fast food company in the Yangtze River Delta, their technical director Lao Zhang made a mistake - he adjusted the vacuum pressure value 30% higher than the industry norm, and as a result, the soup was sucked out when the chicken feet were packaged. Do you think that the vacuum adjustment is a matter of millimeters?
According to the industry data accumulated by our factory over the years (of course, the specific values must be kept confidential), the pressure setting of food packaging equipment is indeed particular. For brittle materials such as puffed food, the pressure value is usually two levels lower than that of liquid packaging; and for high-broth products such as sauces and marinated products, the pressure stability must meet the standards of industrial-grade vacuum systems to ensure a tight seal.
Once I went to a hot pot base factory in the southwest to debug equipment, and their workshop director Lao Li shared an experience: the local altitude difference will affect the baseline value of the vacuum generator. This reminded us that now each machine will be tested for altitude adaptation before leaving the factory to ensure that customers can use it as soon as they get it. Don't mention it, last year more than a dozen customers in the Yunnan-Guizhou Plateau reported that the vacuum adjustment had never been so smooth.
Speaking of common misunderstandings, some masters always think that the higher the pressure value, the better. Just last week, a case was handled: a Shandong customer adjusted the pressure of seafood vacuum packaging to the equipment limit, and as a result, two vacuum pumps burned in three days. In fact, our engineers found through on-site testing that setting the mid-range value according to the industry benchmark can not only ensure the vacuuming effect, but also extend the life of the equipment by more than 20%.
The third-generation intelligent vacuum system newly developed by our factory solves this pain point. The built-in pressure stability self-test module can automatically match the optimal parameter range according to the material characteristics. After a pre-prepared food company in Guangdong tried it last month, the qualified rate of finished products soared directly from 92% to 98.6%. The factory manager called to add an order for ten units.
Recently, when doing technical training for a freeze-dried fruit and vegetable company in North China, their equipment section chief asked a good question: "Will the thickness change of packaging bags in different batches affect the pressure setting?" This is exactly the advantage of our new generation of vacuum generators-through dynamic pressure compensation technology, it can automatically adapt to the packaging material changes of ±0.05mm, which is something that ordinary equipment cannot do.
In the final analysis, vacuum degree adjustment is both a technical job and an experience job. The industry database that our factory is building has already included the pressure reference ranges of 27 common materials. Next time you encounter adjustment problems, you may want to ask our engineers to remotely test the machine, which is guaranteed to be more accurate and efficient than the manual adjustment of the master.
I remember attending the industry exhibition last month, and several colleagues came to ask about our vacuum generator pressure calibration solution. If you ask me, the trick of this business is just eight words: respect science and make use of experience. Next time if you are not sure about the pressure value setting, you are welcome to come to the factory for field testing at any time - our test workshop has hundreds of samples, and we will adjust the golden parameters that best suit your product!
