In the food industry, single-chamber vacuum packaging machines are becoming more and more popular, such as: meat products, seafood, fruits and vegetables, pickles, chilled meat, sauces, condiments, preserved fruits, grain, soy products, etc. Vacuum packaging is increasingly being used. The products packaged in the single-chamber vacuum packaging machine can prevent moisture, oxidation, mildew, and insects, extend the product shelf life, and improve product quality.
We all know that the single-chamber vacuum packaging machine has the functions of vacuuming and heat sealing, but what should we do when we are unable to seal after using the machine? How should it be solved?
First, can not seal, the possible reasons for existence are as follows:
1. The control panel heat seal switch is not selected, or the heating power is not turned on.
2. The heating element of the packaging machine is damaged, or the power supply connection of the heating element is broken.
3. There is a problem with the panel setting and the heating time is set to 0.
4. There is a problem with the control unit and the heating time relay is damaged.
5. Battery valve failure: The sealing solenoid valve is not working, the air bag is not bulged (or the air bag is damaged).
Second, the sealing of the packaging bag is uneven, there are air bubbles in the sealing line, and the sealing is not firm. The possible reasons are as follows:
1. The vacuum chamber sealing strip is not clean enough, there are dirty things or other foreign objects.
2. The set heating time or temperature is too low to seal well.
3. The airbag is not strong enough to cause the sealing line to be pressed tightly.
4. The cooling time set by the control panel is not enough, resulting in a narrowing of the sealing line and bubbles.
5. The heating strip is damaged and the surface is not flat enough.
In general, if there is a problem with the machine, you must first turn off the power of the machine. The machine usually has an emergency stop device. When there is a problem with the machine, you can press this button. This will ensure safe maintenance. If the repair is not possible, you can supply it. Business to solve.

Vaccine For Prevention Of Rabies
Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals
