Have you ever encountered such troubles? The freshly roasted coffee beans are fragrant, but less than a month after bagging, the flavor is greatly discounted. Customers complained that the coffee was sour, the aroma was lost, and the backlog of inventory led to a reduction in profits... Behind these pain points, there is actually the most easily overlooked enemy in coffee packaging-oxygen.
Among the hundreds of coffee brands received by our factory, more than 80% of customers have had headaches for coffee oxidation problems. Although traditional vacuum packaging can isolate some oxygen, coffee beans will still be exposed to air during the packaging process, and the residual oxygen content of ordinary packaging machines is as high as 3%-5%, which is the culprit that accelerates the oxidation of coffee oil and the loss of flavor.
“Breathing” nitrogen replacement makes the coffee packaging machine a flavor guardian
Our third-generation coffee packaging machine uses dynamic nitrogen replacement technology, which is like installing an “artificial lung” on the coffee bag. When the coffee powder falls into the packaging bag, the equipment will first perform 3 cycles of nitrogen flushing to compress the oxygen content in the bag to less than 1%. Compared with the traditional single nitrogen filling, this breathing replacement can accurately control the residual oxygen content and prevent the coffee aroma from being taken away by the “vacuuming”.
Three major process upgrades to solve the problem of freshness preservation
.Dual-channel freshness-locking system : The coffee packaging machine simultaneously injects food-grade nitrogen during the filling process, and forms a nitrogen protective layer through the airflow guide design to isolate the static adsorption generated by the friction between the coffee powder and the inner wall of the packaging bag.
.Intelligent oxygen content monitoring: The infrared sensor equipped in each device detects the residual oxygen value in real time. When the value exceeds 1.2%, the secondary replacement program is automatically triggered, which is 40% more stable than the general industry standard.
.Adaptive sealing technology: According to the expansion characteristics of coffee beans from different origins, the packaging machine can intelligently adjust the heat sealing temperature to ensure that the seal is tight and leak-free. Even customers in plateau areas with an altitude of 3,000 meters have reported that "there is no problem of bulging bags again."
Customer case: Flavor miracle from 30 days to 18 months
A boutique coffee brand in Yunnan once lost the high-end market due to flavor loss during transportation. After switching to our coffee packaging machine, their anaerobic fermented beans were stored at room temperature for 18 months, and the cupping score remained at 85+. The person in charge sighed: "Now we dare to accept cross-border orders. There were zero complaints about the containers sent to Northern Europe last year. Customers said that they could smell the citrus aftertaste the moment they opened the bag."
Why choose our coffee packaging machine?
In the test, our engineers found that the oxidation rate of coffee will increase exponentially when the residual oxygen content is 2%. To this end, we improved the inclination design of the nitrogen filling nozzle to match the nitrogen flow rate with the coffee powder sedimentation rate. This patented technology increases the freshness-locking efficiency by 60%. Now, our coffee packaging machines have served small and medium-sized roasting workshops in 23 countries. Some customers even put the equipment in the store for fresh baking and packaging, using nitrogen fresh-keeping bags as "mobile billboards".
