When receiving the acceptance video sent by an Indonesian customer last month, the workshop director Lao Wang slapped his thigh and said, "It''s done! This coffee packaging machine is more adaptable to the climate than the locals in the rainy season!" In the video, the equipment that is still discharging materials stably in the rainy day is exactly the third-generation moisture-proof model we developed for humid environments.
This story started in the rainy season last year. At that time, a boutique coffee brand in Southeast Asia came to the door and said that their existing coffee packaging machine would go on strike as soon as the rainy season came, and the workshop hygrometer pointer often danced in the red line area. Our after-sales team flew over and saw that there were always water droplets hanging on the seal of the packaging bag, and the problem of coffee powder getting damp and agglomerated was more serious than imagined-this is not a production workshop, it is simply a greenhouse in the tropical rainforest.
"Your coffee packaging machine must be able to swim." The joke of the customer''s production manager has become the focus of our R&D department. Traditional moisture-proof means are not enough here. Ordinary sealing systems are like a raincoat with a hole when they encounter a continuous humidity of 90%. Our redesigned dual-circulation dehumidification module can form a dry airflow barrier inside the equipment. Now the humidity of the working cabin can be suppressed to below the safety line during the preheating stage.
The most troublesome problem is the sealing problem of packaging bags. In a humid environment, the heat sealing knife is prone to produce microbubbles. Our engineers got inspiration from the vacuum packaging of seafood and installed an instantaneous cooling device on the coffee packaging machine. This month, Bali customers reported that the sealing qualification rate is now stable at a high level in the industry, and the coffee powder can be kept as dry and fluffy as when it was just ground in the rainy season.
The key to this breakthrough is the transoceanic video conference at two o''clock in the morning. At that time, the customer''s workshop suddenly lost power, and the humidity sensor of the coffee packaging machine misjudged after restarting. Our technical director Lao Chen took the team to remotely debug for three hours despite the time difference, and finally found that the local unique salt spray corrosion affected the circuit board. Now this moisture-proof system has been specially treated with three protections. During the typhoon season in the Philippines last month, the same equipment could still start normally after a 36-hour power outage.
There was an interesting episode during the customer acceptance. They deliberately placed a pot of tropical plants next to the equipment, saying that they wanted to simulate the most extreme humid environment. As a result, our coffee packaging machine operated stably while breathing out water vapor, but the fern wilted in two days because the workshop was too dry. Now their workshop is hung with the humidity monitor we gave them, and the pointer on the dial always stays steadily in the green area.
This cooperation has brought not only technological breakthroughs, but also allowed us to understand the special needs of tropical areas. Now this moisture-proof technology has been iterated into a mobile solution. Last month, a car-mounted coffee packaging machine was installed for a cooperative in the mountainous area of Yunnan. I heard that their mobile coffee workshop can shuttle through the rainforest and encapsulate sun-dried coffee powder with a dewy scent on site.
During a recent return visit, the Indonesian customer pointed to the Javanese operating instructions newly posted on the equipment and said: "Your moisture-proof system understands the weather here better than the local employees." Although this was a joke, it revealed the true meaning of our research and development - a good coffee packaging machine should not be restricted by the environment, but should be like a coffee tree, taking root and growing in any land.
From tropical rainforests to plateau mountains, these coffee packaging machines that operate stably in humid environments are rewriting industry perceptions. Next month, we will take this moisture-proof solution to participate in international exhibitions, and the booth has specially designed an artificial rainfall experience area. Welcome everyone to experience the coffee powder packaged in the heavy rain - of course, it is in our special transparent packaging bags, so that you can see with your own eyes how the water vapor is blocked outside the bag.
By the way, the Indonesian customer recently placed an additional order, saying that they want to equip their island experience store with a mini moisture-proof model. It seems that in the world of coffee, conquering humidity is equivalent to getting the golden key to open the tropical market. The coffee packaging machines produced by our factory are becoming the "stabilizing force" in the workshops of customers in more humid areas.
