Nov 01, 2018

Vacuum packaging technology is often used in the food industry. After vacuum packaging, food can resist oxidation, so as to achieve long-term preservation.Therefore, it has been widely used. What should be paid attention to when using vacuum packaging machine?Let me tell you a little bit about that.


1. The oil level of the vacuum pump should be 3/4 of the oil window height during operation. If it is lower than 1/2 of the oil window height, it should be filled with high speed vacuum pump oil in time.Please refer to the instructions of vacuum pump for operation.


2. The machine should be placed horizontally and the environment should be well ventilated. The machine must be equipped with a protective grounding line and regularly check if the connection points are in good contact to ensure personal safety.


3. The heating time and temperature must be set in a proper place before the machine works. The principle of starting from low to high should be mastered.


4. Abnormal noise is generated when the machine is working, and the pointer of the vacuum gauge is not moving, indicating that the vacuum pump may be operating in the wrong direction. The phase of its three-phase power supply may be inconsistent with the ex-factory phase.At this point, you only need to replace any two of the three-phase power supply (single-phase power supply does not have this phenomenon).


5. Check the surface of ptfe paint cloth on the sealing part regularly for foreign matter or unevenness to ensure the sealing quality.Replace in time if there is any damage.


6. Check whether the screws in each part of the machine are loose, and whether the vacuum chamber can move around flexibly.A suitable amount of lubricating oil should be added to the moving parts and oil holes.


7. In case of emergency, press the emergency stop button and the machine cover can be opened by itself.


8. The machine should be cut off after work.
