When handling a vacuum bag with an air valve, a small household vacuum packaging machine can accurately extract air to create an ideal vacuum environment with its unique design and technology. It provides a strong guarantee for the needs of household food preservation.
First, it is equipped with a highly sensitive vacuum sensor. After the vacuuming process begins, the sensor monitors the changes in air pressure in the vacuum bag in real time. As the air is gradually extracted, the sensor accurately captures the downward trend of the air pressure value. Once the air pressure approaches the preset ideal vacuum value, for example, between 0.08 and 0.1 standard atmospheric pressure (adjustable according to the preservation requirements of different items), the packaging machine will quickly adjust the vacuum power according to the sensor feedback, slow down the vacuum speed, avoid excessive vacuuming to damage the items in the bag, and ensure that it can be stably maintained at an accurate vacuum level.
Secondly, the performance and design of the vacuum pump are crucial. Small household vacuum packaging machines usually use high-efficiency and low-noise vacuum pumps. This vacuum pump has stable vacuum flow and pressure output characteristics. After connecting to the vacuum bag with air valve, the vacuum pump can accurately adjust the suction force according to the structural characteristics and flow characteristics of the air valve. It can generate a sufficiently strong negative pressure to overcome the resistance of the air valve and smoothly extract the air in the bag. At the same time, the operation of the vacuum pump is precisely controlled by the intelligent control system. In the initial stage of the vacuum, a large amount of air is quickly extracted with a large power, and the power is gradually reduced as the vacuum degree rises, ensuring that the entire vacuum process is smooth and accurate until the ideal vacuum environment is reached.
Furthermore, the connection part between the packaging machine and the air valve is specially designed. The connection part ensures a tight seal with the air valve to prevent air leakage during the vacuum process, thereby ensuring the accuracy of the vacuum. The shape and material of the connecting part can fit the air valve well, so that the air can only be extracted through the vacuum channel of the packaging machine, and will not leak from the connection gap. Moreover, after the vacuum is completed, the connection part can be quickly separated from the air valve, while ensuring that the air valve is tightly closed to prevent the outside air from entering the vacuum bag again and maintain the ideal vacuum state that has been achieved.
In summary, the small household vacuum packaging machine uses advanced vacuum sensors, efficient and stable vacuum pumps and specially designed connecting parts to achieve precise control of air extraction when processing vacuum bags with air valves, successfully creating an ideal vacuum environment, and providing a reliable and efficient preservation solution for households to store various easily oxidized and perishable items, greatly extending the shelf life of items and improving the quality of family life.
