The concave vacuum packaging machine is based on the original packaging machine of the same specification to deepen the vacuum chamber, and at the same time, the concave design can prevent the soup and water from flowing out of the equipment. An overflow port is provided at the bottom of the lower groove. It can be cleaned up regularly. Generally, the vacuum pumps equipped with this machine are relatively large, at least 60 cubic meters per hour or more.
Recessed vacuum packaging machine is suitable for: meat processing, aquatic products, seafood processing, preserved fruits, grains, soybean products, medicinal materials, electrical appliances, vegetable processing, chemical products and other solid, semi-solid, powder and other objects for vacuum packaging. It can prevent the product from oxidation, mildew, corruption, and moisture-proof to extend the storage period of the product.
The main advantages are:
1. Part of the air (oxygen) in the package is eliminated, which can effectively prevent food from spoiling.
2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can prevent food weight loss and taste loss, and prevent secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat transfer, which can improve the efficiency of heat sterilization and avoid the packaging container from rupturing due to the expansion of gas during heat sterilization. In the food industry, vacuum packaging applications are very common, various cooked products such as chicken legs, ham, sausages, grilled fish fillets, beef jerky, etc.; preserved products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh Increasingly, vacuum packaging is used. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of the food.
In addition to controlling the growth and reproduction of microorganisms, the vacuum deoxygenation of the recessed vacuum packaging machine has another important function to prevent food oxidation. Because fats and oils contain a large amount of unsaturated fatty acids, they are oxidized by the action of oxygen, which makes the food taste and deteriorate. In addition, oxidation also causes the loss of vitamin A and C, and the unstable substances in food pigments are affected by oxygen to darken the color.
What is the specific situation to choose a concave vacuum packaging machine?
1. The liquid exceeds one-half of the bag. Under normal circumstances, there is some moisture in the bag that does not need to use the recessed model. Only when the moisture exceeds one-half of the bag, the recessed model is required. The specific recessed size is determined by the size of the article.
2. Thick items. This is a situation that everyone does not understand very much. Normally, solid products do not need to use concave models, but if the items are thicker, the sealing line cannot be at the end of the item when the platform type vacuum packaging machine is used for sealing. When centering, you need to use a concave model to ensure the position of the sealing line, so as to achieve a perfect packaging effect.
3. Sauce products. The first point we talk about liquid is mainly the product containing liquid, such as mustard tuber Flow to the sealing position, thereby affecting the sealing effect, in this case, it is necessary to use a recessed vacuum packaging machine.
