The upper packaging of the vacuum packaging machine is made of stainless steel, with high strength, corrosion resistance, large volume and light weight. The heating elements are all installed in the upper working room, which can avoid short circuit and other faults caused by the impact of packaged items (especially liquids), and improve the reliability of the whole machine. Liquids or sundries dripping on the workbench can also prevent corrosion and rust caused by packing acid, alkali, salt and other items. The whole machine adopts a stainless steel frame structure to ensure that the overall quality of the equipment is balanced and greatly increase the service life of the equipment. The upper studio can work in two working positions, which is easy to operate, high efficiency and save energy. The packaging process is automatically controlled by the electrical system. For different packaging requirements and different packaging materials, there are adjustment knobs such as extraction time, heating time, and heating temperature, which are easy to adjust to achieve the vacuum effect. So, how to operate Xiaokang rice vacuum packaging machine?
The steps of vacuum packaging machine are as follows:
1. Turn on the power: Turn the power selection switch as required, that is, the power indicator is on. The power selection switch points to vacuum for vacuum sealing, and points to vacuum inflation for vacuum inflation sealing;
2. Place the plastic bag containing the items in the vacuum chamber. The mouth of the bag is neatly placed on the heat seal (if inflated packaging, at least one nozzle should be inserted into the mouth of the bag);
3. Press down the cover, and the suction (vacuum) indicator on the panel lights up. The vacuum pump starts pumping, and the cover is automatically sucked. The vacuum knob can adjust the vacuum level according to the packaging requirements. When adjusting, the visual scale is from low to high, and the amplitude is small;
4. When the pumping time reaches the set time (ie the required degree of vacuum), the pumping is finished, the pumping indicator is off, and the pumping indicator is on, indicating that the pumping started. The inflation knob can adjust the length of inflation time (ie, the amount of inflation), the method is the same as above. If inflation is not required, set the power switch to the vacuum position, the program will automatically enter the vacuum packaging, and the inflation indicator will go out;
5. Enter the sealing process. The panel is equipped with heat-sealing time and temperature adjustment knobs to adapt to different thickness materials. When adjusting the time and temperature, the rotation range should be small to prevent the heat-sealing temperature from suddenly increasing.
6. When the set heat-sealing time is reached, the heat-sealing indicator goes out and ends as the heat-sealing, that is, the vacuum chamber enters the atmosphere through the solenoid valve until the lid is automatically lifted and the vacuum inflation packaging process is all over.
