Even if metal is hard,it is easy to become oxidized,when the metal products oxidize,the appearance and the usage will both be affected.To resolve this problem,vacuum packager is also used in packaging metal.

10.What is the structure of vacuum packager?

After reading the previous text,I guess you are more interested about the vacuum packager,the next part is to tell the structure of it.In the basic case,vacuum packager consists of the following components:

vacuum package

Upper and lower vacuum chamber and sealing ring

Generally,vacuum packager is a cavity structure,consists of the upper and lower vacuum chamber and the sealing ring which is between the two chamber.

Hot pressing sealing device

This device is installed in the vacuum chamber,it is composed of heat seal chamber frame,reset device,hot pressing frame and hot sealing chamber.

Vacuum pump,vacuum gauge and vacuum solenoid valve

Vacuum pump is equal to the heart of the vacuum packager because it’s the extraction air device of the machine.

Vacuum gauge is to monitor the vacuum index of the packaging products.

The vacuum solenoid valve is a special valve installed on the vacuum pump,it is connected to the same power supply with the vacuum pump, and the opening and stopping of the vacuum pump directly controls the opening and closing of the solenoid valve.

Time relays, transformers and contactors

There are always two time relays,one is to control the time of vacuum,the other one is to control the time of heat-sealing.

A transformer is a static electrical device. It is according to the principle of electromagnetic induction, a certain level of AC voltage and current into the same frequency of another level of voltage and current equipment.

Contactor is actually a kind of electromagnetic switch, can automatically break the high current circuit.

11.What is the working principle of vacuum packager?

Well,after understanding the structure of vacuum packager,next part is the working principle,in other words,what’s the technology support of vacuum packager.

vacuum package

To explain this question,we have to talk about microorganism,which results in the spoilage of the products.As well as known,the survival of microorganism is depended on oxygen of the air.How about making it lose the oxygen?

Now you can see the working principle of the vacuum packager is so simple,just extracts the air of the packaging pouch,then the microorganism loses its main living environment,the rate of their growth and reproduction are dramatically reduced, or even suppressed .So,the purpose of using vacuum packager is achieved.

12.What is the working process of vacuum packager?

In fact,there are four parts of the whole working process of vacuum packager:vacuum,heat-seal,gas returning and circulation.

vacuum packageVacuum

At the first step,the cover of the vacuum chamber is closed,and then the vacuum pump begins working,at the same time,the vacuum process is started. As this operation goes on,the vacuum index is increased,when it reaches the rated vacuum degree,the vacuum pump stop working.


The second step is the heat-seal,the outer air enters the heat seal chamber through the air inlet,at that moment,the gas in the heat seal chamber is expanding because of the pressure difference between the vacuum chamber and the heat seal chamber.

As a result,the upper thermopress frame begins to move down and press the mouth of packaging pouch,meanwhile,the heat seal transformer starts working and the seal operation is finished.

Gas returning

Next,the air enters the vacuum chamber,the vacuum index return to zero,the hot press frame is reset,then the cover of vacuum chamber is opened.


If the vacuum packager is a double chamber vacuum packager,according to the procedure steps, the vacuum chamber is moved to another vacuum chamber, and the next working cycle is starts,the left and right chambers work alternately to achieve  the cycle repeats.

13.How to use a vacuum packager?

Simply speaking,the operation steps of the vacuum packager is not complex,it is easy for you to use a vacuum packager.vacuum package

Firstly,you should switch the power supply,choose the correct power switch according to your demand,after that,the power indicator is on.

Secondly,put the packaging pouch in the vacuum chamber,pay attention to the mouth,it should be put on the heat sealing strip neatly.

Then,you should close the cover of vacuum chamber,and adjust the knob of vacuum operation to control the vacuum degree according to the packaging requirement.

Next,when it is at the end of the extracting air process, the inflating operation begins, and you can control the length of time by adjust the knob of inflating operation.

After the above steps,the machine enters the heat-sealing part,you should adjust the time and temperature,a vital point is that you need to adjust the knob in a small range.

Finally,when the heat-sealing operation is finished,the cover of the vacuum packager will be opened,it means that the operation process is finished,you can prepare for the next cycle.

14.What are the operation key points of vacuum packager?

vacuum packageAlthough the operation step of vacuum packager is not difficult,there are still some key point you should pay attention to when you use the vacuum packager.

What’s more,the vacuum packager has its own performance range,you can’t make it work overload,too much work may cause damage to the machine itself.

And please don’t maintain the vacuum packager while it is in operation,because when it is in operation,the machine is electric,it is not suggest to maintain it in such a condition.

The last but important,when you need to replace the accessories or reinstall the machine,you should turn off the power supply before the operation.

All above is the key points of operation,during the use of vacuum packager,you should memorize these points all the time,so that you can protect your machine and extend its service life.

15.How to maintain a vacuum packager?

vacuum packageIt is interesting that the machine is similar to human,if you don’t maintain it,it also has a temper and then breaking down.For this reason,you need to maintain the vacuum packager regularly,the maintaining methods are as follows:

The most crucial one is that the vacuum packing machine should be used in the environment where the temperature is -10℃ -50 ℃, the relative humidity is no more than 85%, and there is no corrosive gas, no dust and no explosive danger in the surrounding air.

To ensure the vacuum pump can work normally,you should check the oil of it termly,if there’s moisture in the oil or the oil turns black,you should replace with new oil.

Don’t forget,the magazine filter should be removed and washed every one to two months.

When the vacuum packager has worked for continuous three months,you should add lube to the connecting parts of the machine.

In addition,the sealing strip should be kept clean,or the quality of sealing will be greatly compromised .

In order to avoid collision,don’t place the vacuum packager obliquely in the process of transport.And when install the vacuum packager,you should guarantee the machine can be put on floor stably.

In the operation process,you should ventilate the vacuum packager before turning on the power,on the contrary,at the end of operation,you need to turn off the power firstly.

16.How to deal with the malfunctions while using vacuum packager?

vacuum packageWhereas,it is inevitable that the machine may be out-of-order,what can you do when it’s broken-down?Just as the follow text:

The first situation is that the vacuum degree is low,there are several possible reasons.If the oil of vacuum pump is polluted,too little or too thin,you need to wash the vacuum pump,and add new oil.If the time of extraction is too short,you need to extend it;

If the exhaust filter is blocked,you need to wash or change it;If there is air leakage,you need to turn off the power,and then check whether the solenoid valve, pipe joint, vacuum pump suction valve or the surrounding gasket of the studio have air leakage. 

The second situation is that the heating part occurs malfunctions.On the one hand,it doesn’t heat,you need to check the heater strip,time relay,heating wire and other heating device to find out which part is faulted,then change it.

On the other hand,when the heating device doesn’t stop,if the time relay is out of contact, adjust or replace it. If the AC contactor doesn’t reset, repair or replace it.

The third situation is that there is aloud noise. If the vacuum pump coupling is worn or broken,you need to replace it. If the exhaust filter is blocked or installed in an incorrect position,you need to clean or replace the exhaust filter and install it correctly.If there is oil leakage,check the solenoid valve.

And there are another situation is that the oil returning valve is blocked,you need to remove and wash it.

17.How to choose a proper vacuum packager?

vacuum packageActually,you already have a relatively comprehensive understanding of vacuum packing machine,now you only need to learn how to choose a vacuum packager.Well,there are many types vacuum packager on the market,to find a proper one,you need to consider the follow factors:
