What is nitrogen packing machine?

Nitrogen packing machine is a kind of vacuum nitrogen filling packing machine, which enhances the pressure resistance of the products, and has the functions of gas barrier, freshness preservation, moisture-proof, anti-corrosion, and antioxidant.

What is Nitrogen-filled packaging?

Nitrogen-filled packaging refers to the packaging of foodstuffs in bags filled with inert gases such as nitrogen, carbon dioxide, etc., and then completed with the sealing process.

Oxygen in the air accounts for about 21%, and nitrogen-filled packaging makes the oxygen content in the bag down to 2%~5%.

Working principle of nitrogen packing machine

Nitrogen packaging machine is a kind of machinery and equipment, whose main function is to match the goods with good protective packaging, to reliably keep the packaged goods in a consistent gas environment, and to reduce aging. This kind of machinery and equipment is developed when the traditional packaging method cannot meet the requirements. The common principle lies in the use of targeted gases as fillers, adding a certain amount of gas to the body to form a protective air environment.

The article is put into the packaging container and the air inside the container is encapsulated to the inside of the article; then the container can be injected with a -certain amount of nitrogen, and the air inside the container can be pumped out using a suction machine until the air pressure inside the container drops to the required level of air pressure. During this process, the items will be protected by pure nitrogen gas, thus realizing the long-term preservation of the items.

Nitrogen filling machine is very easy to use and can be adjusted according to the form of packaging, which reduces the moisture in the packaging, and the air pressure of the items can be controlled according to the need, thus better protecting the items' durability.

Working process of nitrogen packing machine

The working process of a nitrogen filling machine for food packaging is mainly divided into the following steps.

a. Users put the items to be packed into the container of the nitrogen filling packaging machine.

b. Adjust the parameters of the nitrogen packing machine according to the different sizes of the articles.

c. Select the appropriate nitrogen filling temperature and turn on the nitrogen filling switch.

d. Start the vacuum pump to extract the outside air and suck the air into the container.

e. Inside the container, put the nitrogen into the container, so that the goods are completely wrapped.

f. Release the pressure and turn off the vacuum pump.

g. Open the valve in the packaging machine to complete the package, ready to be taken away to the user.

Feature of nitrogen packing machine

a. The vacuum system of the vacuum packing machine with nitrogen flushing replaces the vacuum pump with the vacuum generator, the equipment operates safely and reliably without being clogged by impurities in the air and reduces noise pollution.

b. Heat sealing system can be free to choose hot melt packaging materials, sealing length can be adjusted according to customer packaging needs between 500 ~ 1000MM.

c. The nitrogen system of the nitrogen vacuum packaging machine has high purity of nitrogen and more stable performance.

d. The use of packaging materials with excellent barrier properties (airtightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid the weight loss of food, and loss of flavor, but also prevent secondary pollution.

e. The gas inside the vacuum packaging container of vegetables will be excluded, due to the acceleration of heat conduction, therefore improving the efficiency of heat sterilization, but also to avoid the expansion of the gas and the rupture of the packaging container. In the food industry, vacuum packaging applications are very common, a variety of cooked foods such as chicken thighs, ham, sausage, grilled fish fillets, and beef jerky; pickled products such as a variety of sauces and soybean products, dried fruits and other food products that need to be preserved more and more use of vacuum packaging. After a long time of food packaging vacuum preservation, greatly extends the shelf life of food.

f. Packing machine with nitrogen does not contain part of the air (oxygen) inside the packaging container, and can effectively prevent food spoilage.

Advantage of nitrogen packing machine

Draw out the air inside the bag to reach a predetermined degree of vacuum, and then filled with nitrogen, and then complete the sealing process. There are several advantages of using nitrogen food packaging machine.

a. Vacuum nitrogen-filled packaging is beautiful and generous in appearance and can be visualized to its true form. Vacuum packaging shape is broken, it is not easy to check the real shape of its packaging products, packaging grade is not high.

b. Vacuum nitrogen packaging makes the pressure difference between inside and outside the balance of air will not be able to gradually penetrate the bag through the bag microporous, to prevent premature corruption of fresh products metamorphosis.

c. Vacuum nitrogen filling packaging is most suitable for fragile and afraid extruding materials, such as flowers, crisps, leisure food, and so on.

d. For some water-containing food or material, after vacuum packaging, due to the role of differential pressure in the bag, food or material oil and water seepage will affect the internal quality of food or material and external appearance.

e. For some fried food or fruit and vegetable crisps, the use of a food nitrogen generator for vacuum nitrogen packaging can effectively prevent food rancidity or extrusion to extend the storage time.

Application of nitrogen packing machine

Nitrogen flush packaging machine can be used for pet food and animal feed; slowing down the oxidative rancidity of fats and oils, and prolonging the shelf life. Nitrogen flushing and sealing machine can also be used for liquids, semi-fluids, solid particles, powders, pastes of food, fresh fruits, vegetables, rice, sugar, flowers, potato chips, chemicals, precious herbs, fertilizers, precious paintings and calligraphy, electronic components and all kinds of moth-proof, anti-corrosion, moisture-proof, mildew-proof, antioxidant, and so on. The products are packed in vacuum or vacuum nitrogen to extend the shelf life.

Vacuum nitrogen sealing machine is also particularly suitable for all kinds of fresh fruit and food, medicine and chemical industry, the local specialty industry, electronic components, and other industries. In these industries, nitrogen gas flushing sealing machine can achieve anti-oxidation, anti-corrosion, anti-mold, moisture preservation, and storage effect. In addition, it is best to use it in a place with high cleanliness requirements, and it can increase the inflatable function.

Use of nitrogen packing machine

a. Connect the nitrogen source, after connecting the knob is turned up, the amount of nitrogen is also adjusted. There is also an adjustment switch behind the packer on the top of the device, rotate it to the right to adjust the size, and rotate it to the right to increase. After adjusting it to the right, press it down to work.

b. The bag mouth of the product bag must be set inside the inflatable nozzle, the inflatable nozzle set in the product bag inside the set, after putting on the pressure strip, after putting on the good so that you can carry out the packaging work.

c. There is an inflatable switch next to the panel of the packaging machine. When you turn on the nitrogen filling switch, it is first vacuum and then nitrogen filling, and then sealing. If you turn off the inflatable switch, then it is a direct vacuum directly on the sealing and not in the nitrogen.

d. At the time of work, the inflatable volume between the range of 0.03-0.04 inflatable is the best effect. You need to adjust the inflation time and the vacuum time.

Precaution of nitrogen packing machine

a. Take care of the bag before and after inflation. Don't let sharp objects scratch it to prevent air leakage. It is necessary to operate the nitrogen packing machine on a clean table. If there are buttons, zippers, and other hard objects in the stored items, please fold them inside before putting them into the collection bag. When storing in the cabinet or other places, you should also pay attention to the storage location so there are no sharp objects to ensure that the bag is intact.

b. Items should be placed inside the bag as much as possible, at least 3-5 cm from the nitrogen-filled food vacuum packaging machine seal. Large items do not force into.

c. It is important to ensure that the sealing part is clean. If fibers and dust enter, it will reduce the sealing performance. It is recommended to use water-soaked gauze to wipe clean before closing. After closing the nitrogen-filled food vacuum packaging machine, please use your hand to hold the slide in the seal back and forth a few times to ensure that the sealing of the two bands buckles into the groove to ensure the sealing effect.

d. When using the pump, screw the screw interface of the nitrogen flush sealer to the bottom, and press it against the white rubber gasket of the pumping port to ensure that there is no air leakage at the interface. Generally, a large bag needs to be pumped in 3 to 5 minutes, about three to five hundred pumping will have an obvious flattening phenomenon. When using the pump, be careful to pump continuously without stopping.

e. After pumping, please check the seal again to make sure it is sealed.
