As a technician who has been deeply involved in the packaging machinery industry for twelve years, what makes me most proud every day is watching those "iron guys" in the workshop running - especially the nut vacuum packaging machine that our factory has been promoting in the past three years, which has become the "nut preservation expert" in the mouths of old customers. Last week, when Mr. Zhang from the cashew processing factory in Shandong came to inspect the goods, he joked: "Your equipment is simply a 'time pauser' in the nut industry!"
You may be curious, what is the secret of our nut vacuum packaging machine? In fact, the core lies in the word "vacuum". After three years of market research, our R&D team found that the biggest headache for many nut companies on the market is the problem of oxidation and deterioration. Although traditional packaging equipment can also vacuum, for wrinkled nuts such as pecans and almonds, conventional equipment will always leave "dead corners" in the packaging bag.
In order to solve this pain point, we have specially developed a dual-circulation vacuum system. Simply put, it is like giving nuts two "deep breaths": the first time to quickly extract the air in the large bag, and the second time to use the micro-pressure mode to completely exhaust the residual gas hidden in the wrinkles of the kernel. Last year, when the macadamia nut processing plant in Yunnan was tested, the shelf life of the finished product using our equipment was extended by 30% compared with the competitor's products, and the crispness can be maintained after unpacking.
Now let's talk about the operation issues that you are most concerned about. Many bosses are worried that the operation of automated equipment is complicated. In fact, our nut vacuum packaging machine is specially designed with a "fool mode". The new packer Xiao Li was able to operate independently on the first day of use. The Chinese smart screen that comes with the equipment will prompt in real time: "The current cashew packaging recommends vacuuming for 45 seconds" and "It is recommended to switch to flexible packaging mode when pine nut particles are detected." The production line that was just renovated for a Zhejiang customer last week directly reduced the workstations that originally required 6 people to 3 people on duty.
Speaking of customization, we have to mention the mixed nut customers in Inner Mongolia that we served last year. They required to pack three mixed materials of walnut kernels, pumpkin seeds, and dried cranberries at the same time. Our engineering team installed a visual recognition system and a flexible weighing module on the basis of the standard nut vacuum packaging machine. Now their production line can automatically identify the proportion of different materials and accurately control the proportion of dried fruits in each bag, with an error of less than 3 grams.
Customers often ask: "Will vacuum packaging crush nuts?" This is one of the highlights of our equipment. By simulating the buffering principle of manual bagging, an air pressure balance device is designed in the vacuum pumping link. It is like wrapping the nuts with a layer of "air protection film", which not only achieves the vacuum effect, but also avoids mechanical pressure from damaging the kernels. The 6 devices that were just shipped to Vietnam last month are specially used to pack thin-skinned walnuts. The customer took a video during the acceptance inspection - the integrity rate of the walnut kernels in the bag was close to 98%.
From the perspective of Lao Wang, a quality inspector, the most gratifying thing is the iteration and upgrade of the nut vacuum packaging machine over the years. From the initial adjustment of parameters more than a dozen times a day to the continuous operation of 8 hours without jamming, the equipment stability is getting stronger and stronger. The energy-saving model launched this spring saves 15% of electricity compared with the old model at the same production capacity, which is not a small amount for companies that have to pack more than a dozen tons of nuts every day.
Some colleagues may question: Can your equipment really adapt to various specifications? Let's put it this way, from the small bags of daily nuts of Daily Youxian to the 1 kg family pack of Costco, our nut vacuum packaging machine can respond flexibly. The production line that was just debugged for a customer in Jiangxi last month was still packaging 200g of spicy peanuts in the morning, and switched to 500g of original mixed nuts in the afternoon. The whole parameter adjustment process did not exceed 20 minutes.
Recently, the workshop is assembling the eighth batch of equipment sent to Xinjiang, which is specially used for seasonal packaging of fresh walnuts. Looking at these "iron guys" that are about to go to all parts of the country, I often tell new employees: "Our nut vacuum packaging machine is not just a machine, but also a quality guardian for tens of millions of nut companies." If you are also looking for a packaging solution that can lock in freshness and is efficient, you are welcome to come to the factory at any time to see how these "breathing" smart devices work.
